CHANGE OF FINANCIAL YEAR END


Energy Fuels Inc. (Energy Fuels or the
Company) changed its fiscal year-end from September 30 to December 31,
to better align the Companys year-end with the year-ends of its major uranium
customers, certain material subsidiaries and industry peers. As a result of this
change, the Companys most recent financial year is the fifteen (15) month
period beginning on October 1, 2012 and ending on December 31, 2013.





CURRENCY


All amounts stated in this Annual Information Form
(AIF) are in United States dollars, unless otherwise indicated.

SHARE CONSOLIDATION


Effective November 5, 2013, the Company amended its Articles to
consolidate the issued and outstanding common shares of the Company on the basis
of one post-consolidation common share for every 50 pre-consolidation common
shares (the Share Consolidation). All data for periods prior to
November 5, 2013 relating to numbers of common shares, prices of common shares,
number of stock options and warrants, exercise prices of stock options and
warrants and conversion prices of convertible debentures set forth in this AIF
have been adjusted to give retroactive effect to the Share Consolidation. For
the purpose of giving retroactive effect to the Share Consolidation, the Company
has rounded fractional shares to the nearest whole share and rounded fractional
price information to the nearest cent, with fractions of 0.5 or greater rounded
up and fractions of less than 0.5 rounded down. As a result of such rounding
actual amounts may differ. Unless otherwise indicated, references in this AIF
(but not necessarily the documents incorporated by reference herein) to
Common Share are to the common shares of the Company after giving effect to
the Share Consolidation.

In certain cases, forward looking statements can be identified
by the use of words such as plans, expects or does not expect, is
expected, is likely, budget, scheduled, estimates, forecasts,
intends, anticipates or does not anticipate, continue, or believes,
and similar expressions, or variations of such words and phrases or statements
that certain actions, events or results may, could, would, might or
will be taken, occur or be achieved.

Forward-looking statements are based on the opinions and
estimates of management as of the date such statements are made. Energy Fuels
believes that the expectations reflected in this forward-looking information are
reasonable, but no assurance can be given that these expectations will prove to
be correct, and such forward-looking information included in, or incorporated by
reference into, this AIF should not be unduly relied upon. This information
speaks only as of the date of this AIF.

Readers are cautioned that it would be unreasonable to rely on
any such forward looking statements and information as creating any legal
rights, and that the statements and information are not guarantees and may
involve known and unknown risks and uncertainties, and that actual results are
likely to differ (and may differ materially) and objectives and strategies may
differ or change from those expressed or implied in the forward looking
statements or information as a result of various factors. Such risks and
uncertainties include risks generally encountered in the exploration,
development and operation of mineral properties and processing facilities such
as:

- risks associated with mineral and resource estimates, including the risk
  of errors in assumptions or methodologies
- risks associated with estimating production, forecasting future price
  levels necessary to support production, and the Companys ability to increase
  production in response to any increases in commodity prices or other market
  conditions;
- uncertainties and liabilities inherent in mining operations;

3

---

- geological, technical and processing problems, including unanticipated
  metallurgical difficulties, ground control problems, process upsets and
  equipment malfunctions;
- risks associated with labour costs, labour disturbances and unavailability
  of skilled labour;
- risks associated with the availability and/or fluctuations in the costs of
  raw materials and consumables used in the Company's production processes;
- risks associated with environmental compliance and permitting, including
  those created by changes in environmental legislation and regulation and
  delays in obtaining permits and licenses that could impact expected production
  levels or increases in expected production levels;
- actions taken by regulatory authorities with respect to mining and
  processing activities;
- risks associated with the Companys dependence on third parties in the
  provision of transportation and other critical services;
- title risks;
- the adequacy of insurance coverage;
- uncertainty as to reclamation and decommissioning liabilities;
- the ability of the Companys bonding companies to require increases in the
  collateral required to secure reclamation obligations;
- the potential for, and outcome of, litigation and other legal proceedings,
  including potential injunctions pending the outcome of such litigation and
  proceedings;
- the ability of Energy Fuels to meet its obligations to its creditors;
- risks associated with the Companys relationships with its business and
  joint venture partners;
- failure to obtain industry partner, government and other third party
  consents and approvals, when required;
- competition for, among other things, capital, acquisitions of mineral
  reserves, undeveloped lands and skilled personnel;
- incorrect assessments of the value of acquisitions;
- risks posed by fluctuations in exchange rates and interest rates, as well
  as general economic conditions;
- risks inherent in the Companys and industrys forecasts or predictions of
  future uranium and vanadium price levels;
- fluctuations in the market prices of uranium and vanadium, which are
  cyclical and subject to substantial price fluctuations;
- risks associated with asset impairment as a result of decreases in uranium
  prices;
- risks associated with lack of access to markets and the ability to access
  capital;
- the market price of Energy Fuels securities;
- public resistance to nuclear energy or uranium mining;
- uranium industry competition and international trade restrictions; and
- the other factors discussed under Risk Factors in this AIF.

Actual results and developments are likely to differ, and may
differ materially, from those expressed or implied by the forward looking
statements contained in this AIF.

Such statements are based on a number of assumptions which may
prove to be incorrect, including, but not limited to, the following
assumptions:

- that there is no material deterioration in general business and economic
  conditions;
- that there is no unanticipated fluctuation of interest rates and foreign
  exchange rates;
- that the supply and demand for, deliveries of, and the level and
  volatility of prices of uranium, vanadium and the Companys other primary
  metals and minerals develop as expected;

4

---

- that uranium and vanadium prices required to reach, sustain or increase
  expected or forecasted production levels are realized as expected;
- that the Company receives regulatory and governmental approvals for the
  Companys development projects and other operations on a timely basis;
- that the Company is able to operate its mineral properties and processing
  facilities as expected;
- that existing licenses and permits are maintained and renewed as required;
- that the Company is able to obtain financing for the Companys development
  projects on reasonable terms;
- that the Company is able to procure mining equipment and operating
  supplies in sufficient quantities and on a timely basis;
- that engineering and construction timetables and capital costs for the
  Companys development and expansion projects and restarting projects on
  standby, are not incorrectly estimated or affected by unforeseen
  circumstances;
- that costs of closure of various operations are accurately estimated;
- that there are no unanticipated changes in collateral requirements for
  surety bonds;
- that there are no unanticipated changes to market competition;
- that the Companys reserve and resource estimates are within reasonable
  bounds of accuracy (including with respect to size, grade and recoverability)
  and that the geological, operational and price assumptions on which these are
  based are reasonable;
- that environmental and other administrative and legal proceedings or
  disputes are satisfactorily resolved; and
- that the Company maintains ongoing relations with its employees and with
  its business and joint venture partners.

All written and oral forward looking statements or information
attributable to the Company or persons acting on the Companys behalf are
expressly qualified in their entirety by the foregoing cautionary statements.

Forward looking statements speak only as of the date the
statements are made. You should not put undue reliance on any forward looking
statements.

The Company cautions that the foregoing list of assumptions,
risks and uncertainties is not exhaustive. Additional information on these and
other factors which could affect operations or financial results are included
under the headingRisk Factors. The forward-looking
statements and forward-looking information contained in this AIF and the
documents incorporated by reference herein are expressly qualified by this
cautionary statement. The Company does not undertake any obligation to publicly
update or revise any forward looking statements to reflect actual results,
changes in assumptions or changes in other factors affecting any forward looking
statements or information except as expressly required by applicable securities
laws. If the Company does update one or more forward looking statements, no
inference should be drawn that the Company will make additional updates with
respect to those or other forward looking statements.

Statements relating to "Mineral Reserves" or "Mineral
Resources" are deemed to be forward-looking information, as they involve the
implied assessment, based on certain estimates and assumptions, that the Mineral
Reserves and Mineral Resources described may be profitably produced in the
future.

CAUTIONARYNOTETOUNITEDSTATESINVESTORSCONCERNING ESTIMATESOFMINERALRESERVES ANDMINERALESTIMATES


This AIF has been prepared in accordance with the requirements
of Canadian securities laws, which differ from the requirements of United States
securities laws. Unless otherwise indicated, all reserve and resource estimates
included in this AIF, and in the documents incorporated by reference herein,
have been prepared in accordance with Canadian National Instrument 43-101 -
Standards of Disclosure for Mineral Projects (NI 43-101) and the
Canadian Institute of Mining, Metallurgy and Petroleum classification system. NI
43-101 is a rule developed by the Canadian Securities Administrators (the
CSA) which establishes standards for all public disclosure an issuer
makes of scientific and technical information concerning mineral projects.

Canadian standards, including NI 43-101, differ significantly
from the requirements of the United States Securities and Exchange Commission
(the SEC), and reserve and resource information contained or
incorporated by reference in this AIF, and in the documents incorporated by
reference herein, may not be comparable to similar information disclosed by
companies reporting under United States standards. In particular, and without
limiting the generality of the foregoing, the term resource does not equate to
the term reserve. Under United States standards, mineralization may not be
classified as a reserve unless the determination has been made that the
mineralization could be economically and legally produced or extracted at the
time the reserve determination is made.

The SECs disclosure standards normally do not permit the
inclusion of information concerning Measured Mineral Resources, Indicated
Mineral Resources or Inferred Mineral Resources or other descriptions of the
amount of mineralization in mineral deposits that do not constitute reserves
by United States standards in documents filed with the SEC. United States
investors should also understand that Inferred Mineral Resources have a great
amount of uncertainty as to their existence and as to their economic and legal
feasibility. It cannot be assumed that all or any part of an Inferred Mineral
Resource will ever be upgraded to a higher category. Under Canadian rules,
estimated Inferred Mineral Resources may not form the basis of feasibility or
prefeasibility studies. United States investors are cautioned not to assume
that all or any part of Measured or Indicated Mineral Resources will ever be
converted into mineral reserves. Investors are cautioned not to assume that all
or any part of an Inferred Mineral Resource exists or is economically or
legally mineable.

Disclosure of contained pounds or contained ounces in a
resource estimate is permitted disclosure under Canadian regulations; however,
the SEC normally only permits issuers to report mineralization that does not
constitute reserves by SEC standards as in place tonnage and grade without
reference to unit measures. The requirements of NI 43-101 for identification of
reserves are also not the same as those of the SEC, and reserves reported by
the Company in compliance with NI 43-101 may not qualify as reserves under SEC
standards. Accordingly, information concerning mineral deposits set forth herein
may not be comparable to information made public by companies that report in
accordance with United States standards.

GENERALDEVELOPMENTOFTHEBUSINESS


THREEYEARHISTORY

Fiscal Year Ended September 30, 2011

During the year ended September 30, 2011, the Company completed
a public offering for net proceeds of Cdn$10.84 million net of cash costs. A
total of 460,000 units were issued at a price of Cdn$25.00, with each unit
comprised of one Common Share and one-half of one warrant. Each whole warrant
entitles the holder to purchase one Common Share at a price of Cdn$32.50 per
share until March 31, 2015. The proceeds were used to continue advancing the
licensing and construction planning process for the Piñon Ridge Mill, to
maintain existing permits and facilities, for resource expansion on mineral
properties and to continue evaluation and possible acquisition of additional
mineral properties as part of Energy Fuels uranium property consolidation
strategy.

On January 5, 2011 the Company received conditional approval,
and on March 7, 2011 final approval, from the CDPHE for a Radioactive Materials
License (the Piñon Ridge License) for the 500 ton per day Piñon Ridge
Mill facility, allowing Energy Fuels to build and operate a conventional uranium
mill. On October 26, 2011, the Company received approval from the United States
Environmental Protection Agency (the EPA) for construction of the
tailings impoundment and evaporation pond facilities for the Piñon Ridge
Mill.

The Company expanded its uranium property position adjoining
the Energy Queen mine by acquiring two Utah School and Institutional Trust Lands
Administration (SITLA) Leases and 13 unpatented claims from Uranium One
Inc. in November 2010. In February 2011, the Company issued 20,921 Common Shares
valued at $1.21 million to purchase the rights for ten unpatented mining claims
(the Hollie Claims), located in Emery County, Utah from Titan Uranium
USA, Inc. The Hollie Claims are located about 150 highway miles from the White
Mesa Mill and are surrounded by the Companys San Rafael Uranium Project.

Energy Fuels also assembled sufficient contiguous historical
resource acreage to begin permitting its Sage Plain uranium and vanadium project
in the Uravan Mineral Belt with Utahs Division of Oil, Gas, and Mining
(UDOGM). In November 2010, CPP, in which Energy Fuels held a 50%
interest at that time, acquired 94 contiguous unpatented mining claims (1,942
acres) in the Sage Plain area of Utah and Colorado at the south end of the
Uravan Mineral Belt, along with a Utah SITLA Lease on two nearby properties (733
acres). They are located in close proximity to two other SITLA Leases that were
already owned by CPP and are about 54 highway miles from the White Mesa Mill.
The properties were acquired for a nominal cash payment and overriding
royalties. In February 2011, the Company issued 21,298 Common Shares valued at
$1.01 million to purchase the mining lease and all related data for the Calliham
mine, located in the Sage Plain area. The property was contributed to CPP after
Energy Fuels joint venture partner, Lynx-Royal JV LLC (Lynx-Royal),
agreed to a plan to reimburse Energy Fuels for the contribution. On July 27,
2011, Energy Fuels paid $0.50 million to purchase the mining lease (Crain
Lease) and all related data for the Crain Property, located in the Sage
Plain area, from Uranium Energy Corporation. The property was contributed to the
CPP joint venture after Lynx-Royal agreed to the contribution and paid EFRC
$0.25 million for its share of the cost. In October 2011, Energy Fuels purchased
a 20-year mining lease in the Sage Plain District from privately held Nuclear
Energy Corporation for $1.50 million (the Skidmore Lease). The Skidmore
Lease is located on approximately 709 acres in San Juan County, Utah, and
includes large portions of the historic Calliham mine that is adjacent to the
Calliham Lease, the Crain Lease, and other mining claims and SITLA Leases
already owned or controlled by Energy Fuels through CPP. All of these
properties now comprise the Sage Plain project. See Mineral Projects - Sage
Plain below.

Energy Fuels did not have any properties in production during
FY-2011, and therefore produced no U3O8 or V2O5 during the fiscal
year.

Fiscal Year Ended September 30, 2012

During the year ended September 30, 2012, the Company and Titan
Uranium Inc. (Titan) entered into a Business Combination Agreement
dated December 5, 2011 whereby Energy Fuels agreed to acquire, by way of a plan
of arrangement, all of the outstanding common shares of Titan. The acquisition
was completed on February 29, 2012. Titans principal asset was the Sheep
Mountain Project in Wyoming. The Company issued an aggregate of 1,781,280 Common
Shares in connection with the acquisition of Titan.

On March 1, 2012, Energy Fuels completed the Updated
Preliminary Feasibility Study dated April 13, 2012 for the Sheep Mountain
Project (2012 PFS), which reported the Probable Mineral Reserve for the
Sheep Mountain Project at 18.4million lbs. U3O8 contained in 7.5 million tons at
an average grade of 0.123% eU3O8. Total Indicated
Resources are 12.9 million tons containing 30.3million lbs. U3O8 at an average grade of 0.117%e U3O8,
which includes the Probable Mineral Reserve number described above. See Mineral Projects  Sheep
Mountain Projectbelow.

On June 21, 2012, the Company completed a private placement of
710,010 subscription receipts at a price of Cdn$11.50 per subscription receipt
for gross total proceeds of $8.01 million. Each subscription receipt was
exchangeable upon completion of the acquisition of Denisons US Mining Division
described below for one Common Share and one-half of one warrant. Each whole
warrant entitles the holder to purchase one additional Common Share at a price
of Cdn$13.25 until June 22, 2015. The Company used the net proceeds of Cdn$7.11
million for working capital and general corporate purposes related to operations
of the US Mining Division, defined below.

On June 29, 2012, the Company completed the acquisition of all
of the mining assets and operations located in the United States (the US
Mining Division) of Denison Mines Corp. (Denison). The Company
acquired the US Mining Division through the acquisition of all of the issued and
outstanding shares of Denisons subsidiaries, Denison Mines Holdings Corp.
(DMHC) and White Canyon Uranium Limited (WCUL), and the
assignment of all amounts owing to Denison or any affiliate of Denison (other
than DHMC, WCUL or any direct or indirect subsidiary of DMHC), in exchange for
the issuance of an aggregate of 8,508,817 Common Shares. Upon completion of the
acquisition, two additional directors were appointed to the Board of Directors
of Energy Fuels. After completion of the acquisition, Energy Fuels changed the
name of DMHC to Energy Fuels Holdings Corp. (EF Holdings). The transaction was accounted for as a business combination with
the Company identified as the acquirer, owing to the fact that post-transaction
Energy Fuels now met the criteria of a business.

10

---

As a result of the Denison acquisition, the Company acquired
the White Mesa Mill (the Mill), an operating mill central to its existing
Colorado, Utah and Arizona holdings, as well as significant producing,
developmental and exploration properties in the same area, including the Henry
Mountains Project, the Daneros Mine, the La Sal Properties and the Arizona Strip
Properties. See Mineral Projectsbelow. The Mill, along with the
properties in the proximate area, represents the Companys cash generating
unit.

On July 3, 2012, the Company entered into an underwriting
agreement with a syndicate of underwriters whereby the underwriters agreed to
purchase, on a bought deal basis, 22,000 floating-rate convertible unsecured
subordinated debentures (Debentures) at a price per Debenture of
Cdn$1,000 for total gross proceeds of $21.55 million. The transaction closed on
July 24, 2012, and the Company received net proceeds of $19.19 million, net of the
underwriters fees and expenses. The principal amount of the Debentures are
convertible into Common Shares at a conversion price of Cdn$15.00 per share. The
Company used the net proceeds of the offering for sustaining capital for the
Company's existing mine operations, mine permitting and development of the
Company's existing properties, repayment of certain indebtedness, and for
working capital and general corporate purposes. The Debentures mature on June
30, 2017 and are convertible into Common Shares at any time prior to maturity at
a conversion price of Cdn$15.00 per Common Share.

As a result of the acquisition of the US Mining Division from
Denison on June 29, 2012, Energy Fuels became a producing company. Energy Fuels
uranium production in the period from the acquisition (June 29, 2012) through
September 30, 2012 was 310,480 pounds of U3O8. During this same period, uranium
sales totaled 447,000 pounds of U3O8 at an average realized price of $55.83 per
pound of U3O8. There was no vanadium produced or sold during this same
period.

At the time of the acquisition, the Company was producing
uranium ore at its Arizona 1 Mine in Arizona and Daneros Mine in Utah, and was
producing uranium and vanadium ore at its La Sal Complex in Utah, which includes
the Beaver and Pandora mines.

Also at the time of the acquisition, the Company was developing
and refurbishing its Pinenut mine in Arizona.

Period from October 1, 2012 to December 31, 2013

During the period from October 1, 2012 to December 31, 2013,
the Company acquired the interests of Aldershot Resources Ltd.
(Aldershot) in the Sage Plain Project for $0.75 million in cash, the
cancellation of debt owed by Aldershot to Energy Fuels, and 70,551 shares of
Common Stock. In the transaction, Energy Fuels acquired Aldershots ownership
interest in CPP and ASP, two 50/50 joint ventures between subsidiaries of Energy
Fuels and Aldershot. CPP holds a portion of the properties in the Sage Plain
Project area, including the Calliham lease, the Crain lease, four SITLA Leases
and 94 unpatented mining claims on land managed by the U.S. Bureau of Land
Management (BLM). As a result of the acquisition, Energy Fuels now owns
100% of the Sage Plain Project, which is located about 15-miles northeast of
Monticello, Utah and about 54 road miles from Energy Fuels White Mesa Mill. In
addition, Energy Fuels acquired Aldershots interest in ASP which holds several
prospective exploration properties in northern Arizona. See Mineral Projects
 Sage Plain Projectbelow.

During the quarter ended December 31, 2012, the Company placed
the Daneros Mine and the Beaver and Pandora mines in the La Sal Complex on
standby status due to lower uranium spot market prices.

On January 28, 2013, Energy Fuels acquired a 16.5% interest in
Virginia Energy Resources Inc. (Virginia Energy) (TSX.V:VUI;
OTCQX:VEGYF) as part of a non-brokered private placement financing. Energy Fuels
acquired 9,439,857 common shares of Virginia Energy at a price of Cdn$0.42 per
share, for an aggregate subscription price of $4.16 million. The subscription
price was satisfied by a combination of $0.25 million of cash and the issuance of
437,028 common shares of Energy Fuels.

Shaft sinking operations at the Companys Canyon Project in
Arizona commenced in early April 2013, and were placed on standby in November
2013, due to market conditions and to simplify and lessen the expense of
litigation. Up to that point, the shaft had been sunk to a depth of 280 feet,
and all surface development on the project had been completed, including the
head-frame, the hoist, the evaporation ponds, environmental monitoring
facilities and all buildings. The Company agreed to maintain such activities on
standby until the earlier of a decision by the Arizona District Court on the
merits of the current litigation at the Canyon Project or December 31, 2014. See
Legal and Regulatory Proceedings  Canyon Project below.

On June 11, 2013, the Company entered into a definitive
arrangement agreement to acquire by way of a plan of arrangement all of the
issued and outstanding shares of Strathmore Minerals Corp. (Strathmore). The
transaction was completed on August 30, 2014. See Significant Acquisitions 
Acquisition of Strathmore Minerals Corp. below.

On June 13, 2013, the Company announced the completion of a
bought deal private placement of units of the Company (Units) pursuant
to an underwriting agreement with Dundee Securities Ltd., Haywood Securities
Inc. and Cantor Fitzgerald Canada Corporation. A total of 947,616 Units were
issued at a price of Cdn$7.00 per Unit for total gross proceeds of $6.52
million. Each Unit consists of one common share of the Company and one-half of
one common share purchase warrant. Each whole warrant entitles the holder
thereof to acquire one common share of the Company at a price of Cdn$9.50 at any
time until June 15, 2015.

On June 26, 2013, Energy Fuels Common Shares began trading in
the United States on the OTCQX under the symbol EFRFF. The Companys Common
Shares traded on the OTCQX until they were approved for listing on the NYSE MKT.
See below for discussion of NYSE MKT listing.

On October 16, 2013, the Company completed a public offering
(Offering) of 625,000 common shares at a price of Cdn$8.00 per share
for aggregate gross proceeds of $4.83 million. The Offering was conducted by way
of a short form prospectus dated October 9, 2013 through a syndicate of
underwriters comprised of Dundee Securities Ltd., Cantor Fitzgerald Canada
Corporation and Haywood Securities Inc. (the Underwriters). In
addition, 30,963 compensation warrants were issued to the Underwriters.

The Company changed its fiscal year-end from September 30 to
December 31, to better align the Companys year-end with the year-ends of its
major uranium customers, certain material subsidiaries and industry peers. As a
result of this change, the Companys most recent financial year is the 15-month
period beginning on October 1, 2012 and ending on December 31, 2013.

In order to facilitate a listing of the Companys Common Shares
on the NYSE MKT, effective November 5, 2013, the Company completed a
consolidation of its Common Shares on the basis of 50 pre-consolidation Common
Shares for each one post-consolidation Common Share. The Share Consolidation was
approved by the shareholders of the Company at a special meeting of shareholders
held on October 30, 2013 The Common Shares of Energy Fuels began trading on the
Toronto Stock Exchange (TSX) on a post-consolidated basis on November
5, 2013.

on the NYSE MKT stock exchange, under the ticker symbol UUUU.

On December 17, 2013, Energy Fuels announced that it had
entered into a Strategic Relationship Agreement (SRA) with Korea
Electric Power Corporation (KEPCO). KEPCO is the largest electric
utility in South Korea, responsible for 93% of South Koreas electricity
generation and the development of nuclear projects worldwide. The key objectives
of the SRA are to establish a long-term and strategic collaborative relationship
and to promote the development of each companys businesses. The SRA addresses a
number of areas of interest for both Energy Fuels and KEPCO, including the
development of Energy Fuels Wyoming projects, KEPCOs seat on the board of
directors of Energy Fuels, visitation and secondment rights, and future
qualified bidding by Energy Fuels on uranium concentrate supply contracts for
KEPCO and its affiliates.

Other Events Since December 31, 2013

Effective February 15, 2014, Mr. Graham G. Moylan resigned from
his position as Chief Financial Officer of the Company in order to pursue an
investment banking opportunity. Mr. Daniel G. Zang, previously, the Companys
Vice President, Controller and Chief Accounting Officer assumed the role of
Chief Financial Officer of the Company effective February 16, 2014. Mr. Zang has
many years of experience as Chief Financial Officer, Controller, Chief
Accounting Officer and other positions with a number of public and private
companies, including Controller and Treasurer of General Moly, Inc. and Vice
President and Controller of Cyprus Copper Company, an operating division of
Cyprus Minerals Company that earned annual revenues in excess of  $1
billion.

On March 3, 2014, the Company completed the replacement of its
$28.17 million regulatory bonding portfolio, utilizing three different qualified
sureties. As a result of replacing the bonds, the Company released $12.34
million of previously restricted cash. Prior bonding arrangements, covering all
of the Companys mines and mills, required the Company to post 100% cash
collateral to back the currently outstanding $26.78 million undiscounted
decommissioning liability.

SIGNIFICANTACQUISITIONS

Acquisition of Strathmore Minerals

On August 30, 2013, Energy Fuels acquired, by way of a plan of
arrangement (the Arrangement), all of the issued and outstanding shares
of Strathmore Minerals Corp. ("Strathmore"). Energy Fuels filed a
business acquisition report dated September 27, 2013 in respect of the
acquisition of Strathmore. Under the Arrangement, Strathmore shareholders
received 0.0294 Common Shares of Energy Fuels for each common share of
Strathmore held. In total, Energy Fuels issued 3,665,395 Common Shares to
shareholders of Strathmore, plus 63,024 Common Shares to certain officers and
directors of Strathmore in satisfaction of Strathmores restricted share units.
Haywood Securities Inc. and Dundee Securities Ltd. acted as joint financial
advisors to Energy Fuels.

Effective as of the closing of the Arrangement, Energy Fuels
increased the size of its board of directors to eleven (11) directors. Steven
Khan, the former President and a Director of Strathmore, and Eun Ho Cheong, the
Vice President Overseas Resources Project Development for Korea Electric Power
Corporation (KEPCO) were appointed as directors. Mr. Cheong resigned as
a director effective January 13, 2014, and was replaced by Tae Hwan Kim, General
Manager of Overseas Resources Project Development for KEPCO.

13

---

The Arrangement enabled Energy Fuels to acquire the following
key projects: a 60% interest in the Roca Honda Project, a uranium development
project located in northwest New Mexico; the Gas Hills Project, a uranium
development project located in central Wyoming, the Juniper Ridge Project, a
uranium development project located in south central Wyoming; and the Copper
King Project, a gold/copper project located in southeast Wyoming.

Under the Arrangement, the Company acquired a subsidiary of
Strathmore, called Roca Honda Resources LLC (through Strathmore US) which holds
a 60% interest in the Roca Honda Project. The other 40% of Roca Honda Resources
LLC is held by affiliates of Sumitomo Corporation of Japan. The Roca Honda
Project is one of the largest and highest grade uranium development projects in
the United States. An NI 43-101 Preliminary Economic Analysis (PEA) was
prepared by Roscoe Postle Associates for the Roca Honda Project in August 2012,
which can be found on SEDAR. The report estimates that the project contains 2.08
million tons of Measured and Indicated Mineral Resources with an average grade
of 0.404% U3O8 containing 16.8 million lbs. of U3O8. In addition, the report
estimates that the project contains another 1.45 million tons of Inferred
Mineral Resources with an average grade of 0.411% U3O8 containing 11.9million
lbs. of U3O8. The PEA also shows attractive project economics including a nine
year mine life, estimated operating costs of $24/lb. and annual production of
2.6million lbs. of U3O8 per year. The Company believes that significant
synergies could be achieved by trucking resources from the Roca Honda Project to
the Companys White Mesa mill near Blanding, Utah, rather than constructing a
new mill in New Mexico.

Strathmore had previously been permitting and developing the
Gas Hills Project in a strategic venture with KEPCO. The Company believes that
synergies can be achieved by combining aspects of the Gas Hills Project with the
Companys Sheep Mountain Project, located only 28 miles away. An NI 43-101
Technical Report for the Gas Hills Project was prepared by Chlumsky, Armbrust
& Meyer LLC in March 2013. The report estimates that the project contains
2.3 million tons of Indicated Mineral Resources with an average grade of
0.13% U3O8 containing 5.4 million lbs. of U3O8. In addition, the report estimates
that the project contains another 3.9 million tons of Inferred Mineral Resources
with an average grade of 0.07% U3O8 containing 5.5 million lbs. of U3O8.

The Company is evaluating the development of the Juniper Ridge
Project as a stand-alone uranium project or as part of a regional uranium
project with the Sheep Mountain and/or Gas Hills projects. The Company has
received an independent technical report containing an updated mineral resource
estimate and preliminary economic assessment for the Juniper Ridge Project (the
Juniper Ridge Technical Report), prepared in accordance with NI 43-101.
The Technical Report is dated January 27, 2014, and has been filed on the
Companys website and under its profile on SEDAR. The Technical Report was
prepared by Douglas L. Beahm, P.E., P.G. and Terrence P. McNulty, P.E., D.Sc.,
each of whom is an independent qualified person under NI 43-101. According to
the Technical Report, the project has 5.23 million tons of Indicated Mineral
Resources containing 6.12million lbs. of eU3O8 with an
average grade of 0.058%. Furthermore, the Technical Report estimates that the
project has 107,000 tons of Inferred Mineral Resources containing 182,000 lbs.
of eU3O8 with an average grade
of 0.071% . Mineral resources are reported at a minimum thickness of two feet; a
minimum grade of 0.02% eU3O8; and a minimum Grade time Thickness (GT) of 0.10.
According to the PEA, the Juniper Ridge Project has a net present value of $21.3
million (at an 8% discount rate) and is expected to generate an internal rate of
return of 22% prior to US income tax. The PEA assumes an open pit mine operation
with heap leach uranium recovery having a 10-year mine life; average annual
production of 515,000 lbs. of U3O8; and an averageuranium price of
US$65/lb. for the assumed period of production (2019-2028). The project is
expected to require initial capital expenditures of US$33.3 million.

14

---

Under the Arrangement, the Company also acquired Wyoming Gold
(through Strathmore, Strathmore US, and Saratoga Gold). Wyoming Gold holds the
Copper King Project, a gold/copper project located in southeastern Wyoming. An NI 43-101 Technical Report on the
Copper King project was prepared by Mine Development Associates in August 2012.
The report estimates that the project contains 59.75 million tons of measured
and indicated mineral resources with average grades of 0.015 oz/ton Au and
0.187% Cu containing 926,000 oz. of Au and 223 million lbs. of Cu. The report
also estimates that the project contains 15.62 million tons of inferred mineral
resources with average grades of 0.011 oz/ton Au and 0.20% Cu containing 174.000
oz of Au and 62.53 million lbs. Cu.

ENERGYFUELS
      BUSINESS


OVERVIEW

Energy Fuels is engaged in uranium mining, milling,
development, permitting and exploration with an operating uranium mine, mines on
standby, projects in permitting and development, and exploration properties
located in the United States. Energy Fuels assets include its 100% ownership of
the White Mesa Mill in Utah. Energy Fuels also produces vanadium as a co-product
from some of its mines in Colorado and Utah. In addition, Energy Fuels recycles
other uranium-bearing materials, not derived from conventional ore, referred to
as "alternate feed materials", for the recovery of uranium, alone or in
combination with other metals, at its White Mesa Mill.

The Company entered the uranium industry in 2007 with a mission
to build a fully-integrated uranium and vanadium production company through
exploration, development, mining, milling and sales: primarily targeting
immediately economic uranium properties on the Colorado Plateau and in the
broader western United States.

The Companys principal assets as of December 31, 2013 include

For the short-term, given the stagnant low spot price of
uranium discussed above, Energy Fuels intends to cut back production quantities
to approximately 500,000 pounds of U3O8 for FY-2014 and has
securedpurchases of uranium. These sources of uranium along with
present finished goods on hand will allow the Company to meet all of its
contractual commitments through at least December 31, 2015. During the first
half of FY-2014 Energy Fuels will continue to mine at the Pinenut mine. Mining
at the Companys Arizona 1 mine was placed on standby in February 2014, upon
depletion of the currently economic uranium resource at that time. During the
first half of FY-2014 the Company intends to continue processing alternate feed
materials as well as mill and process stockpiled ore from the Pinenut and
Arizona 1 mines at the White Mesa Mill. The Company then expects to place all
mine production and mineral processing at the White Mesa Mill on standby during
the second half of FY-2014. The Company will continue to receive alternate feed
materials at the White Mesa Mill for future processing.

With respect to its sales strategy in the short-term, as a
result of the relatively weak uranium spot price, Energy Fuels will primarily
focus on sales pursuant to its term contracts, which require deliveries of
800,000 lbs. during FY-2014, of which 300,000 pounds will be from purchased
material. The Company expects its sales to result in average realized prices of
$58.42/lb., which would be well-above the expected spot market price. At
current prices, the Company does not expect to produce any product for sale at
spot prices, nor does the Company expect to sell any existing product at spot
prices. Also, if low prices continue, the Company may not restart mineral
processing activities at the White Mesa Mill during 2015. The Company intends to
closely monitor U3O8 prices, and may change operating plans under actual or
expected market conditions as necessary.

Though prices in the short and medium term are under intense
pressure from excess supplies, as reported in the The Ux Consulting Company, LLC
(UxC), Uranium Market Outlook  Q1 2014, in the longer term, Energy
Fuels believes prices will improve and intends to continue to strengthen its
position as a leading uranium company in the United States, through business
development activities, including development of existing projects, as market
conditions warrant. Energy Fuels will also look to further acquire uranium
properties in the United States, if favorable opportunities arise. Environmental
and permit compliance and maintenance activities will continue at the White Mesa
Mill in order to maintain the facility to be able to restart mineral processing
operations as required. Energy Fuels currently intends to maintain several mines
on standby and continue to permit other new projects, thereby positioning the
Company to increase production as market conditions warrant.

The Company utilizes various industry forecasts to assist in
its business planning, evaluation of existing and future mining projects, and
assessment of its valuation of long-lived assets. In March 2014 UxC published
its Uranium Market Outlook  Q1 2014. In this report UxC reduced its annual
price projections for the period from 2014 to 2025 compared with their Q4 2013
report (published in December 2013). The Company is currently evaluating the
revised forecast, along with other industry forecasts, to determine the
Companys expectation of future uranium prices. In the event the Company
concludes that a significant deterioration in expected future uranium prices has
occurred, the Company will assess whether an impairment allowance is necessary
which, if required, could be material, and may adjust its operations.

MARKETING

The Uranium Industry

Over the medium- to long-term, nuclear power capacity and power
generation are growing, while uranium production will likely struggle to meet
this growing demand. As a result, it should be expected that prices will need to
rise to higher, sustained levels to support the new mines that will be required
to meet increasing demand. However, in the short- to medium-term, there is
uncertainty about uranium prices as a result of ample worldwide uranium
inventories and the slower-than-expected restart of Japans nuclear reactors. As
a result of current market conditions, many producing uranium mines have been
placed on standby, and uranium development projects are being delayed around the
World.

Future Uranium Demand

World net electricity consumption is expected to increase by
69% by 2035, according to the World Energy Outlook 2013 (the "WEO 2013"),
a report issued by the International Energy Agency. Total demand for electricity
is projected to increase on average by 2.2% per year from 19,004 terawatt-hours
in 2010 to 32,150 terawatt-hours in 2035. This increased demand appears to be
driven by both economic and population growth. China and India account for over
49%, and OECD countries make up less than 17% of the new demand. As a result of
high fossil fuel prices, energy security concerns, improved reactor designs and
climate change concerns, new nuclear capacity is expected to be a significant
part of meeting this growth in electricity demand.

According to the World Nuclear Association (WNA), as
of February, 2014, there are 434 nuclear reactors operable worldwide in 30
countries, generating 374.3 gigawatts of electricity. Of perhaps greater
significance, 70 nuclear reactors are under construction in 14 countries
including 49 under construction in China, India, South Korea and Russia. The 70
reactors under construction are expected to require over 100 million pounds of
U3O8 for initial cores and an additional 38 million pounds of U3O8 annually once
they are in operation. China, in particular, has a very aggressive new build
program underway, including 28 reactors under construction and 176 on order,
planned or proposed. Overall, there are 483 new reactors on order, planned or
proposed around the World.

Nevertheless, the industry continues to feel the after-effects
of the March 2011 Japanese earthquake and tsunami, and resulting nuclear
incident. However, while some countries, such as Germany, have announced
intentions to reduce their reliance on nuclear power, most countries have
reaffirmed their support for nuclear power. Japan is expected to begin to
restart some of its existing reactors during 2014, and political support for
nuclear power in Japan continues to increase. Seventeen reactors in Japan have
applied for restarts. However, the process has been slower than expected. Due to
the slow restart of Japans nuclear fleet, stockpiles of uranium in that country
have built to significant levels. The loss of ongoing demand in Japan along with
the inevitable build-up of inventory resulting from Japanese delivery
commitments under long term contracts have imposed both a real and a
psychological overhang on the uranium market. Many estimates for Japanese
reactor restarts during 2014 can be found in the financial press. Most expect at
least some restarts during the year, but Energy Fuels estimates the actual
number is probably somewhere between two units and six units. Any restarts at
all should bolster the uranium market, and this effect is believed by the
Company to have been seen in late February 2014 with a resurgence in uranium
equity values.

18

---

Significantly, the governments of China, India, South Korea and
Russia have all announced their intention to move ahead with their nuclear
plans. In addition, several non-nuclear countries are moving ahead with their
plans, such as Saudi Arabia which plans to build up to 16 reactors, Poland with
plans to build 6, and the United Arab Emirates which has two under construction
and contracts for two more. The 70 new reactors now under construction worldwide
are expected to require approximately 38 million pounds of uranium per year, and
those that are on order, planned or proposed are expected to require
approximately 268 million pounds of uranium per year. Contrasting this with
expected 2014 global reactor demand of just over 171 million pounds clearly
illustrates the growth anticipated in the uranium business.

Primary Uranium Supply

Uranium supply is the biggest variable in the supply-demand
equation. During the time that the accumulated inventories from over production
in the 1970s were being drawn down, primary mine production accounted for only
approximately 50% of demand. A number of new mines have been brought into
production over the last few years while others are in various stages of
development. However, production now accounts for approximately 90% of demand,
and more mines will be required to meet the increasing future demand and to
replace mines that are being depleted.

UxC has estimated in its Uranium Market Outlook  Q1 2014
that existing mine production plus new planned and potential mine production
will increase primary uranium supply from 154 million pounds in 2013 to 200
million pounds in 2020. Kazakhstan was earlier perceived to be increasing
production by as much as 21% between 2012 and 2020. However, current estimates
by UxC place that Kazakh production growth at only about 10%. In order to reach
these estimated primary uranium supply levels to the extent not filled by
current production and secondary sources, it is anticipated that a number of
large new mines, around the world, will also need to be developed and brought
into production. It is reasonable to expect that prices will need to increase
appreciably to support the additional production and significant capital
expenditures required to develop and build the mines to meet these production
forecasts.

Secondary Uranium Supply

Primary mine production currently supplies approximately 90% of
demand. The balance of demand is supplied from secondary sources such as
remaining excess commercial inventories, reprocessing of spent fuel, and
inventories held by governments. The down-blending of highly-enriched uranium
(HEU) from nuclear weapons programs was by far, the most significant of
the secondary supplies, providing 18 to 24 million pounds per year. The HEU
program was officially terminated at the end of 2013. As excess inventories due
to the Japanese reactor shutdown are brought into balance, it is expected that
the supply gap created by the HEU termination will have to be made up from new
primary mine production or other secondary sources.

Excess commercial inventories, which were once one of the major
sources of secondary supplies during the period from the early 1970s to the
early 2000s, are believed to have largely been consumed (other than the
stockpiles of uranium in Japan that have accrued as a result of the Fukushima
incident). However, some government inventories, particularly in the U.S. and
Russia, remain. The disposition of these inventories may have a market impact
over the next 10 to 20 years, although the rate and timing of this material
entering the market is uncertain. The market is however currently being affected
by the release of DOE material related to continued cleanup operations at USEC
Inc.

Reprocessing of spent fuel is another source of secondary
supply, but is expected to satisfy only 3% to 4% of demand. Expansion of this
secondary source would require major investments in facilities, which the
Company believes could only be supported by a significant increase in long-term
uranium prices.

19

---

The shutdown of nuclear reactors in Japan as a result of the
Fukushima incident has also resulted in a reduction in enrichment demand, which
has allowed enrichment facilities to use their excess capacity to produce more
fuel from the same amount of uranium feed, at little or no additional cost. UxC
estimates that this will effectively place 12  18 million pounds per year of
additional U3O8 into the market for as long as excess capacity remains in the
enrichment business.

However, in the longer term, UxC expects that secondary sources
of supply will fall from 52 million pounds to 29 million pounds per year from
now to 2020.

Uranium Prices

Most of the countries that use nuclear-generated electricity do
not have a sufficient domestic uranium supply to fuel their nuclear power
reactors. Their electric utilities must secure their required uranium supply by
entering into medium- and long-term contracts with foreign uranium producers and
other suppliers. These contracts usually provide for deliveries to begin two to
four years after they are signed and provide for delivery from four to ten years
thereafter. In awarding medium- and long-term contracts, electric utilities
consider, in addition to the commercial terms offered, the producers uranium
reserves, record of performance and costs, which are important to the producer's
or suppliers ability to fulfill long-term supply commitments. Electric
utilities procure their remaining requirements through spot and near-term
purchases from uranium producers and other suppliers, including other utilities
holding excess inventory and governments.

While long-term demand is steadily growing, short-term demand
is affected in large part by utilities uncovered requirements. To the extent
that they have uncovered demand in the near term, they generally will purchase
on the spot market, which in turn affects the spot price. Currently, there is
relatively little uncovered demand, so utility buying is primarily discretionary
and price driven.

Historically, spot prices are more volatile than long-term
prices. The spot price began 2013 at $43.50 per lb. and fell steadily throughout
the first half of the year reaching the $35.00 per lb. level in late July where
they have generally remained.

The long-term price ranged from $56.00 per pound U3O8 at the
beginning of 2013, and cycled between $55.00 and $57.00 until September. At the
end of September 2013, long-term prices fell to $50.00 per pound where they are
currently. Long-term prices are driven more by production costs and future
supply-demand forecasts than by customer inventories, but even long-term prices
have fallen due to the lack of long term contracting activity by the
utilities.

Competition

Uranium production and marketing are international in scope and
characterized by a relatively small number of companies operating in only a few
countries. The top eight producers accounted for about 82% of the worlds
primary mine supply in 2012.

About 80% of the worlds production came from five countries,
namely Kazakhstan, Canada, Australia, Niger, and Namibia. Kazakhstan passed
Canada in 2009 as the largest producer, a role Canada had held for 17 years.

Marketing Uranium

20

---

The uranium market is truly global in scope. The value of the
commodity is so high per unit weight that it can literally be shipped anywhere.
A shipping drum of U3O8 will have a typical gross weight of about 920 pounds, of
which about 850 pounds will be U3O8. At a price of $35.00 per pound, a short ton
of U3O8 would have a market value of $70,000. Typical freight costs for an
overseas uranium shipment would represent only 1 - 2% of the current spot market
value of the product delivered.

Energy Fuels has sold its uranium under a combination of
long-term and spot contracts. The long-term contracts have a variety of pricing
mechanisms, including fixed prices, base prices adjusted by inflation indices
and/or spot price or long-term contract reference prices. Time of delivery
during a year under long-term contracts is at the discretion of the customer, so
the Companys delivery obligations may vary markedly from quarter to quarter.
Spot sales were priced at or near published industry spot prices.

During the 15 months ended December 31, 2013, approximately 80%
of Energy Fuels total sales volume was sold under long-term contracts, with the
remainder sold in the spot market. The Company currently has three long-term
contracts in place. One contract is for 350,000 pounds (±10%) per year from 2010
to 2015 inclusive. This agreement also provides for the purchase of 350,000 lbs.
per year after 2015 subject to certain conditions. The second contract is for
delivery of 1,100,000 pounds of U3O8 over a period of six years beginning in
2011. The third contract was re-negotiated in 2013 and now provides for the
delivery of 300,000 pounds of U3O8 per year for 2014 through 2017 inclusive.

Energy Fuels will continue to seek long-term contracts at
prices sufficient to support the development of its mineral assets as well as to
seek out spot sales opportunities that make financial sense for the Company.

Sales of U3O8 for 2014 are expected to be 800,000 pounds in FY
2014, all pursuant to existing long-termcontracts at an average realized price
of $58.42 per pound. The Company may consider additional U3O8 sales as market
conditions and concentrate supplies warrant.

Vanadium

In the past, Energy Fuels has sold its vanadium both as both V2O5 and as ferrovanadium (FeV) throughspot sales to
industry end-users and trading companies. Vanadium sales by Energy Fuels during
FY-2013 were 1.5 million pounds. However, because all of Energy Fuels vanadium
producing uranium mines are currently on standby due to low uranium prices,
there will be no vanadium sales in 2014.

OPERATIONS

White Mesa Mill

The White Mesa Mill is a fully licensed uranium and vanadium
processing facility located in southeastern Utah, near the Colorado Plateau
District, the Henry Mountains Complex, the Ambrosia Lake District, the Arizona
Strip and the White Canyon district. The Mill is approximately six miles south
of the city of Blanding, Utah. Access is by U.S. Highway 191.

Construction of the Mill began in 1979, and
conventionally-mined uranium/vanadium ore was first processed in May 1980. The
Mill uses sulfuric acid leaching and a solvent extraction recovery process to
extract and recover uranium and vanadium. The Mill has been operated on a
campaign basis since its initial start-up due to variable uranium market
conditions.

21

---

In addition to the conventional ore circuit, the Mill has a
separate vanadium co-product recovery circuit. The Mill also has a third circuit
for the processing of certain types of alternate feed materials, which was built
in 2009. This circuit enables the Mill to process both conventional ore and
alternate feed materials simultaneously. See Operations  White Mesa Mill 
Alternate Feed Materialsbelow.

The Mill is licensed to process an average of 2,000 tons of ore
per day and to produce up to 8.0 million pounds of U3O8 per year. In full
operation, the Mill employs approximately 150 people.

Current Condition and Operating Status

In late 2006, the previous owner of the White Mesa Mill, began
a program to refurbish the mill. The refurbishment program included the purchase
of mobile equipment, restoration of the vanadium roasting, fusion and packaging
circuits, replacement of major pumps and component drives, modernization of the
mills instrumentation and process control systems, and completion of the
relining of tailings Cell 4A. The total cost of the refurbishment program was
approximately $31.0 million and was completed in 2008.

In April 2008, the Mill began processing uranium/vanadium
conventional ore and producing uranium concentrate in the form of U3O8.
Production of vanadium began in July 2008 after completion of the refurbishment
of the vanadium circuit. Processing of conventional ore continued through the
end of March 2009 when the Mill was shut down for approximately thirty days for
relining of the semi-autogenous grinding Mill and other critical maintenance
activities. Processing of conventional ore recommenced near the end of April
2009; however, conventional ore processing was discontinued near the end of May
for the remainder of 2009 due to the decline in uranium prices. The Mill began
processing conventional ore again in March 2010 and continued through to June
2011. Conventional ore processing recommenced in November 2011 and continued
until early March 2012, at which time conventional ore processing ceased for
routine maintenance at the Mill. Conventional ore processing recommenced at the
Mill in August 2012 and continued until early June 2013. The White Mesa Mill is
expected to begin processing conventional ore again in May 2014 until July 31,
2014. The alternate feed circuit is expected to process materials until April of
2014.

Energy Fuels acquired the Mill on June 29, 2012. All production
after that date has been for the account of Energy Fuels. From June 30, 2012
through December 2012, the Mill processed approximately 16,016 tons of ore from
the Arizona 1 Mine, 25,543 tons from the Daneros Mine, 16,046 tons from the
Pandora Mine (La Sal Complex), and 32,122 tons from the Beaver Mine (La Sal
Complex).

During calendar 2013 the Mill processed 18,370 tons of Arizona
1 ore, 2,052 tons of Pinenut ore, 11,181 tons of Daneros ore, 41,782 tons of
Pandora ore, 40,669 tons of Beaver ore, and 8,894 tons of purchased ore. See
Operations  White Mesa Mill  Ore Purchase and Toll Millingbelow.

The processing of four different alternate feed materials has
occurred since June 29, 2012, using the separate alternate feed circuit built in
2009, as well as the main Mill circuit after conventional ore processing was
completed in June of 2013

Production at the Mill over the past six years is shown below.
(Note, only production since June 30, 2012 has been for the account of Energy
Fuels).

    Production since June 30, 2012 has been for the
      account of Energy Fuels. Production prior to that date was for the account
      of the previous owner.


Mill License

The Mill operates under a Radioactive Materials License issued
by the State of Utah (the White Mesa License). The White Mesa License
came up for renewal on March 31, 2007. A License Renewal Application was
submitted to the Utah Department of Environmental Quality (UDEQ),
Division of Radiation Control (the DRC) on February 28, 2007. The White
Mesa License renewal process remains underway. The White Mesa License remains in
effect in its current form during the renewal process.

Tailings Disposal & Evaporation Ponds

Synthetic lined cells are used to contain tailings and
solutions for evaporation. The Company operates two tailings cells during normal
operations. As each tailings cell is filled, the water is drawn off and pumped
to an evaporation pond and the tailings solids are allowed to dry. As each
tailings cell reaches final capacity, reclamation begins with the placement of
interim cover over the tailings. Additional cells are excavated, and the
overburden is used to reclaim previous cells. In this way, there is an ongoing
reclamation process.

In June 2007, refurbishment of Cell 4A, which was originally
built in 1989, commenced. The refurbishment was completed in August 2008 and an
operating permit from the DRC was issued in September 2008. The cell has been in
operation since that time and provides approximately 2.0 million tons of
tailings capacity.

23

---

The licensing process for tailings Cell 4B was commenced in
2009. In late October 2009, UDEQ issued its approval to commence the earthwork
for Cell 4B. Approval to complete the earthwork and commence placement of the
cell liners was received in June 2010. Construction of the cell was completed in
December 2010 and final approval to begin use of the cell was received in
January 2011. Cell 4B is currently only being used for additional evaporation
capacity and will provide approximately 2.0 million tons of tailings
capacity.

Environmental

In 1999, some chloroform contamination was detected in the
groundwater at the White Mesa Mill site that appears to have resulted from the
operation of a temporary laboratory facility located at the site prior to and
during the construction of the Mill and from septic drain fields that were used
for laboratory and sanitary wastes prior to construction of the Mills tailings
cells. Elevated concentrations of nitrate and chloride were also observed in
some monitoring wells at the Mill site in 2008, a number of which were
up-gradient of the mills tailings cells. In addition, the Mill has reported
consecutive exceedances of Groundwater Compliance Limits (GWCLs) under
the Mills Groundwater Discharge Permit (GWDP) for several constituents
in several wells, and there is a decreasing trend in pH in a number of wells
across the Mill site that have caused the pH in a number of compliance
monitoring wells to have dropped below their GWCLs. These exceedances and pH
trends include wells that are upgradient of the Mill facilities and are
currently being evaluated. See Mineral Projects  Environmental and Safety
Matters in the United Statesbelow.

Alternate Feed Materials

The White Mesa License gives the Company the right to process
other uranium-bearing materials known as alternate feed materials pursuant to
an Alternate Feed Guidance adopted by the U.S. Nuclear Regulatory Commission
(NRC). Alternate feed materials are uranium-bearing materials, which
usually are classified as waste products by the generators of the materials.
Requiring a routine amendment to the White Mesa License for each different
alternate feed, the Company can process these uranium-bearing materials and
recover uranium, in some cases, at a fraction of the cost of processing
conventional ore. In other cases, the generators of the alternate feed materials
are willing to pay a recycling fee to the Company to process these materials to
recover uranium and then dispose of the remaining by-product in the mills
licensed tailings cells, rather than directly disposing of the materials at a
disposal site. By working with the Company and taking the recycling approach,
the suppliers of alternate feed materials can significantly reduce their
remediation costs, as there are only a limited number of disposal sites for
uranium-bearing materials in the United States. Alternate feeds are particularly
attractive to Energy Fuels because they carry no associated mining costs.

To date, the Mill has received 15 license amendments,
authorizing the Mill to process 18 different alternate feed materials. Of these
amendments, nine involve the processing of feeds provided by nuclear fuel cycle
facilities and private industry, and one has involved the processing of material
from the United States Department of Energy (DOE). These ten feed
materials have been relatively high in uranium content and relatively low in
volume. The remaining five amendments have been to allow the Mill to process
uranium-bearing soils from former defense sites, known as FUSRAP sites, which
were being remediated by the U.S. Army Corps of Engineers. These materials are
typically relatively low in uranium content but relatively high in volume.

In the United States, Energy Fuels is involved primarily in
eight mining districts: the Colorado Plateau, the Henry Mountains, White Canyon,
the Arizona Strip, Crooks Gap, Gas Hills, Poison Basin, and Grants Districts.
The mineral properties that are currently material to the Company are: the La
Sal Complex (Energy Queen, Beaver, and Pandora Mines) the Whirlwind Mine, and
Sage Plain Project, in the Colorado Plateau District; the Tony M Mine and the
Bullfrog property (both in the Henry Mountains Complex), in the Henry Mountains
District; the Daneros Mine, in the White Canyon District; the Arizona 1 Mine
(now on standby due to the depletion of the economic resources), the Pinenut
Mine, the Canyon Project, and EZ1 and EZ2 properties, in the Arizona Strip
District; the Sheep Mountain Project in the Crooks Gap District of central
Wyoming, the Gas Hills Project in the Gas Hills District of central Wyoming, the
Juniper Ridge Project in the Poison Basin District of south central Wyoming; and
the Roca Honda Project, in the Grants District in northwest New Mexico. The
mines are shown on the map and are described in further detail below.



Colorado Plateau

In June 2006, Denison, the previous owner and operator of some
mines on the Colorado Plateau, announced that it was restarting mining activity
in the United States with the re-opening of several mines in the Colorado
Plateau District. Over a twelve month period, Denison reopened five mines in the
Colorado Plateau District. In late 2008, Denison began rehabilitation of the
Beaver mine and this mine began shipping ore to the White Mesa Mill in February
2009. As a result of declining uranium prices, Denison placed the Topaz mine on
standby in

January 2009. In March 2009, Denison placed the Rim and
Sunday/St. Jude mines on standby, followed by the West Sunday mine which was
placed on standby in October 2009. In October 2012, Energy Fuels placed the
Beaver mine on standby, due to decreases in commodity prices. The Pandora mine
was placed on standby in December 2012. All of the mines are maintained so that
they can be restarted with little relative effort or development costs. The
Whirlwind Project was refurbished by the Company in 2008. The Energy Queen and
Sage Plain Projects have not operated in recent years. See Mineral Projects
- Whirlwind, Mineral Projects  La Sal Complex, Mineral Projects  Sage
Plain Project, Non-Material Mineral Properties  Sunday Complex below.

Henry Mountains

The Tony M mine commenced mining in 2007 and continued through
March 2009, at which time the mine was placed on standby, due to market
conditions. During that period, mined ore, as well as ore from historic stockpiles at the site, was shipped to the White Mesa
Mill. The mine remains on care and maintenance at this time. See Mineral
Projects  Henry Mountains Complex below.

Arizona Strip

Mining of the Companys Arizona 1 Mine commenced in December
2009, and continued until the mine was placed on standby in February 2014 due to
the depletion of the currently identified  resource. Mining at the Companys Pinenut Mine
commenced in July of 2013 and is expected to continue until mid-2014 at which
time ore production is expected to be placed on standby. Development at the
Canyon Project was suspended in November of 2013. See Mineral Projects 
Arizona Strip below.

Daneros

The first ore from the Daneros Mine in the White Canyon
District was delivered to the White Mesa Mill in December 2009, when the project
was owned by Utah Energy Corp. and a toll milling campaign was conducted in the
second half of 2010. In June 2011, Denison acquired Utah Energy Corp. and
continued to operate the mine. The Daneros Mine is now owned by Energy Fuels,
and ore from the mine was delivered to the White Mesa Mill until the mine was
placed on standby in October 2012. See Mineral Projects  Daneros Mine
below.

Sheep Mountain

No ore has been mined at the Sheep Mountain Project in Wyoming
since the Companys acquisition in February 2012. The last mining on the
property occurred in the 1980s. See  Mineral Projects  Sheep Mountain
Project below.

Gas Hills

No ore has been mined at the Gas Hills Project in Wyoming since
the Companys acquisition in August 2013. The last mining on the property
occurred in the 1980s. See Mineral Projects  Gas Hills Project below.

Juniper Ridge

No ore has been mined at the Juniper Ridge Project in Wyoming
since the Companys acquisition in August 2013. The last mining on the property
occurred in the 1970s. See Mineral Projects  Juniper Ridge Project
below.

Roca Honda

No ore has been produced from the Roca Honda Project in New
Mexico since the Companys acquisition in August 2013 No commercial mining has
ever occurred on the property. See Mineral Projects  Roca Honda
Project below.

Ore Purchase and Toll Milling

In July 2007, an ore purchase program was initiated to provide
additional mill feed for the White Mesa Mill, including a schedule listing the
price to be paid per ton and adjusted periodically in response to changing
factors such as uranium and vanadium prices, milling cost, and uranium and
vanadium recoveries. The Company expects to continue this program, as market
conditions warrant.

The Mill received 2,423 tons in 2008 at an average grade of
0.19%U3O8 and 1.0% V2O5. In
2009, a total of 9,077 tons were received at an average grade of
0.32%U3O and 0.66% V2O5 from
11 different mines. 110 tons of ore were received under the ore purchase
program in 2010, and 589 tons were received in 2011. 1,602 tons of ore were
received under this program in FY-2012, with the ore lots closed out and paid
for in October 2012, at an average grade of 0.265% U3O8. In FY-2013, the Company purchased 8,500
tons of ore at an average grade of 0.23%U3O8 from
two sources in Colorado and Utah.

Mineral Exploration

Energy Fuels holds a number of exploration properties in the
Colorado Plateau, White Canyon, Gas Hills, Wyoming, Grants, and Arizona Strip
Districts. Exploration drilling has been conducted in the Colorado Plateau and
Wyoming Districts in recent years, with the majority of the work directed toward
brown fields drilling to extend active mining areas.

Energy Fuels has conducted intermittent exploration drilling on
18 different projects in the period from February 2007 through December 2013.
The projects include: the Whirlwind Mine; Energy Queen Mine, the Torbyn property
(on Tenderfoot Mesa); the Farmer Girl property; HC claims and DOE Lease C-G-26
(on Calamity Mesa)  New Verde Mine; DOE Lease C-CM-24 and the Henry claims (on
Club Mesa); Willhunt claims (contiguous with the Sunday Mines Complex); the Luke
claims (since abandoned); the DOC claims (since abandoned); the MCT claims
(since abandoned); the MO claims (since abandoned); Bush Canyon (since
abandoned); the Sage Plain Project (includes drilling on the Sage claims,
Calliham lease, Crain lease, and Skidmore lease); Hop Creek (since abandoned);
amd four breccia pipe targets in Arizona (Cyclone, Weap, Wu and Pocket). In
addition, prior to Energy Fuels acquisition of these projects, Denison
performed exploration drilling on a number of the properties in the US Mining
Division, including the Sunday Complex and La Sal Complex and underground core
drilling at Arizona 1 Mine. The Companys predecessors conducted exploration
drilling at several additional properties, including Sheep Mountain (by Titan)
and Juniper Ridge and Gas Hills (by Strathmore).

In 2014, limited exploration drilling is planned at Arizona 1
Mine and Pinenut Mine (underground core drilling). In the Arizona Strip
District, Energy Fuels holds 100% interest in several claims blocks, all of
which host confirmed breccia pipes features. Mineralization has been encountered
in past drilling on a number of these features, and additional deep drilling is
required to confirm mineral resources. Energy Fuels plans to drill six deep
exploration holes in the future, to confirm a known discovery and to support
mineral resource estimation, on a breccia pipe known as DB-1, although no
drilling is planned for FY-2014. See Mineral Projects  Non-Material Mineral
Properties  Exploration Properties below.

Other Projects

In addition to the foregoing, the Company has conducted
operations in the following two projects:

Sheep Mountain Project:

The Company is permitting the Sheep Mountain Project, an
underground and open pit uranium development project located in Wyoming. In
FY-2013, the Company submitted a revised Plan of Operations (PO) to the
BLM, which included redesign of the heap leach processing area and potential
transportation of the ore to an off-site processing facility. The revision is
expected to give the Company more flexibility in processing of the resource. The
Environmental Impact Statement (EIS) for the project is being prepared
by the BLM and a third-party contractor. A revision to the Wyoming mine permit
was submitted to the Wyoming Land Quality Division in January 2014 and is
currently being reviewed by the agency. Baseline studies and design of the
processing and heap leach facility have been completed for the NRC license
application. Submittal of the license application has been temporarily deferred
as the Company evaluates alternatives for processing the ore.

The Company is also conducting care and maintenance activities
on the Sheep Mountain Project site and collecting baseline data. See Mineral
Projects  Sheep Mountain Projectbelow.

Roca Honda Project:
The Roca Honda project is at an advanced stage of permitting. The Draft
Environmental Impact Statement (DEIS) was completed by the USFS in April 2013,
and the company expects the Final Environmental Impact Statement (FEIS) to be
published in early 2015. Other major permits required for Roca Honda include a
Permit to Mine issued by the New Mexico Mining and Minerals Division, a
Discharge Permit issued by the New Mexico Environmental Department, and a Mine
Dewatering Permit issued by the New Mexico State Engineers Office. The Mine
Dewatering Permit was approved in December 2013. The two other major permits are
in the agency review stage with a draft Discharge Permit expected in the first
half of 2014, and the Permit to Mine expected after approval of the FEIS in mid-
to late-2015. Permit approvals from the U.S. Army Corps of Engineers and the
U.S. Environmental Protection Agency are also required for discharge of treated
mine water associated with mine development and operation. Applications for
these two permits are also presently undergoing agency review. The Company is
also conducting care and maintenance activities on the Roca Honda Project site.
See Mineral Projects  Roca Honda Project below.Henry Mountains Project:
The Company is currently preparing mine plans for permitting purposes for the
Bullfrog portion of the project, and plans to initiate baseline studies of the
property in the spring of 2014. The approved permitting schedule is based on
having the BLM Plan of Operations (PO), the UDOGM Large Mine Notice of Intent
(NOI), and other required state and federal permit applications submitted in
4th Quarter 2014. The Company is also conducting care and maintenance activities
on the Henry Mountains Project site. See Mineral Projects  Henry Mountains
Project below.

Piñon Ridge Mill:

The Company has permitted the proposed Piñon Ridge uranium and
vanadium mill located in the Paradox Valley of Colorado. This proposed 500 tpd
mineral processing facility would be the first uranium mill constructed in the
U.S. in over 30 years. In FY-2012, the Company assisted the State of Colorado in
defending a legal challenge to the Piñon Ridge License (which was granted in
March 2011) from nongovernmental organizations. In June 2012, a court ruled in
favor of the State and Company on the ten substantive environmental, health and
safety claims. However, the court also set aside the Piñon Ridge License pending
the completion of an administrative hearing, which occurred in November 2012. In
April 2013, the State of Colorado reissued the Piñon Ridge License. The Company
is now defending a new legal challenge from non-governmental organizations.

The Company is conducting care and maintenance activities on
the Piñon Ridge Mill site. See Mineral Projects  Piñon Ridge Millbelow.

Notes:

(1) White Mesa  Ore
Stockpile includes stockpiled U3O8 which has been mined from the Arizona 1 and
Pinenut Mines, wheremineral reserve and mineral resource estimates
have been prepared in accordance with NI 43-101.(2)
Mineral Resources that are not Mineral Reserves do not have demonstrated
economic viability.(3) The Measured and Indicated
Mineral Resources were estimated at various block cut-off grades specifically
appropriate to the deposit type.(4) The Inferred
Mineral Resources were estimated at various block cut-off grades specifically
appropriate to the deposit type.(5) The Sheep Mountain
Indicated Mineral Resource includes Probable Mineral Reserves of 18,365,000 lbs.
eU3O8 in 7,453,000 tonsat a grade of 0.123%.(6) Other  includes defined resources on the Willhunt, Torbyn and
Farmer Girl exploration projects.(7) The Arizona 1 Mine
was placed on standby in February 2014 due to the depletion of the economic
resources.(8) The number shown represents the  total mineral resources for the Roca Honda Project.  Energy Fuels controls 60% of the project.

Notes:(1)
    Includes all production from October 1, 2012 to
      Dec. 31, 2013.(2)
    Mineral Resources that are not Mineral Reserves do not
      have demonstrated economic viability.(3)
    Large areas of the original resource were inaccessible to
      reconciliation due to the nature of the mining method (open stoping). This
      number represents an estimate of that part of the original resource
      removed based on production sent to the mill.(4)
    Noneconomic/unrecoverable at market conditions prevalent
      at Dec. 31, 2013.(5)
    Reflects adjustment due to deviation error discovered as
      mining began. Also reflects economic conditions requiring elevation of
      0.2% U3O8cut-off to 0.3%
      U3O8.(6)
    The Sage Plain project is held by Colorado Plateau
      Partners LLC, which, as at September 30, 2011 and September 30, 2012 was a
      joint venture owned as to 50% by a subsidiary of the Company and as to 50%
      by a subsidiary of Aldershot Resources Ltd. On October 1, 2012, the
      Company acquired Aldershots 50% interest in CPP, thereby acquiring 100%
      of the Mineral Resources. See Mineral Projects  Sage Plain
      Project below.(7)
    Henry Mountains  includes the Bullfrog (Indian Bench and
      Copper Bench deposits) and Tony M (Southwest and Tony M deposits). See
      Mineral Projects  Henry Mountains Complex below.(8)
    Other includes defined resources on the Willhunt,
      Torbyn and Farmer Girl exploration projects.(9)
    As Redd Block and Energy Queen share a common boundary,
      calculations resulting in the resource at Redd Block have resulted in an
      engineering/classification change for Energy Queen. The table reflects the
      results with resources apportioned according to the boundary placement.(10)
    The Arizona 1 Mine was placed on standby in February 2014
      due to the depletion of the economic resources.

The Henry Mountains Complex

The Henry Mountains Complex is 100% owned by Energy Fuels. It
is comprised of the Bullfrog property, hosting the Indian Bench and the Copper
Bench deposits, and the Tony M property, hosting the Southwest deposit and the
Tony M deposit and mine.

Except as noted, the following description of the Henry
Mountains Complex is based on the technical report dated June 27, 2012 entitled
Technical Report on the Henry Mountains Complex Uranium Property, Utah,
U.S.A., prepared by William E. Roscoe, Ph.D., P.Eng., Douglas H. Underhill,
Ph.D., C.P.G. and Thomas C. Pool, P.E. of Roscoe Postle Associates Inc.
(RPA) in accordance with NI 43-101 (the Henry Mountains Technical
Report). Each of the authors of the Henry Mountains Technical Report is
independent of Energy Fuels and a qualified person for purposes of NI
43-101. The report contains mineral resource estimates for the Indian Bench,
Copper Bench, Southwest and Tony M deposits.The Henry Mountains
Technical Report is available on SEDAR at www.sedar.com.



Property Description and Location

The Henry Mountains Complex is a single contiguous property
located in eastern Garfield County, Utah, 15 to 20 miles north of Bullfrog Basin
Marina on Lake Powell and approximately 40 air miles south of the town of
Hanksville, Utah. It is situated three miles west of Utah State Highway 276. The
Henry Mountains Complex includes the Bullfrog property (which includes the
Copper Bench and Indian Bench deposits) located to the north and the Tony M
property located to the south (which includes the Southwest and Tony M
deposits).

The Henry Mountains Complex is comprised of 202 unpatented BLM
mining claims totaling approximately 3,665 acres and one 640 acre SITLA Lease.
All Henry Mountains property holdings are in good standing. All unpatented
mining claims are subject to an annual federal mining claim maintenance fee of
$140 per plain plus approximately $10 per claim for county filing fees.
Unpatented mining claims expire annually, but are subject to indefinite annual
renewal by filing appropriate documents and paying the fees described above. The
SITLA Lease renews annually for as long as the annual rental payment ($640) and
the advanced minimum royalty payment is made. The surface rights are owned by
the federal government and administered by the BLM, with the exception of the
SITLA Lease which has associated State surface rights. Seventeen of the claims,
comprising a portion of the Tony M property, are subject to an escalating annual advance minimum royalty based on the
uranium spot price, and a 4% yellowcake royalty, less taxes and certain other
deductions. There is also a vanadium production royalty which is a 2% gross
royalty less certain deductions. The SITLA Lease has an annual rental of $640
and is subject to royalties set by the State of Utah including: an escalating
annual advance minimum royalty based on the uranium spot price; a uranium
royalty of 8% of gross value less certain deductions; and a vanadium royalty of
4% of gross value less certain deductions. However, the vanadium grade is too
low to be economic at current or reasonably foreseeable market conditions.

There are no outstanding environmental liabilities to which the
project is subject.

When Denison operated the Tony M Mine in 2007-2008, a number of
surface facilities were constructed, including a power generation station,
compressor station, fuel storage facilities, maintenance building, offices, and
dry facilities. An evaporation pond which was originally constructed when the
Tony M Mine was in operation in the 1980s, and which is used for storage and
evaporation of mine water, was reconstructed by Denison to allow for dewatering
of the mine.

Please see Mineralization section below for the
location of all known mineralized zones and mineral resources. Please see
Permitting section below for the current status of permitting and
approvals for the project.

Accessibility, Climate, Local Resources, Infrastructure and
Physiography

Road access to the Henry Mountains Complex is by paved Highway
276, running between Hanksville and Bullfrog Basin Marina, Utah. A gravel road,
maintained by Garfield County and extending west from Highway 276, provides
access to the southern end of the property. An unimproved county road passes by
the portal of the Tony M mine and extends northerly across the property. A
network of unimproved, dirt exploration roads provide access over the property
except for areas of rugged terrain. The Bullfrog Basin Marina airstrip is
located approximately 15 miles south of the Henry Mountains Complex. The Henry
Mountains Complex is located in a relatively remote area of Utah, and
infrastructure is somewhat limited. The distance to Energy Fuels White Mesa
Mill is 117 miles.

During operation of the Tony M Mine, electricity was generated
locally, as is the case for Ticaboo. Skilled labour can be recruited from the
region, which has a tradition of uranium mining. Materials and supplies are
transported to the site by truck about 275 miles from Salt Lake City, and about
190 miles from Grand Junction, Colorado. The distance to the Energy Fuels White
Mesa Uranium-Vanadium Processing Facility near Blanding, Utah, is 117 miles.

The climate is distinctly arid, with average annual
precipitation of approximately eight inches. Local records indicate the
temperature ranges from a minimum of -10°F to a maximum of 110°F. The vegetation
consists primarily of small plants, including some of the major varieties of blackbrush, sagebrush, and rabbit brush. A few small junipers are also present.
Year-round operations are expected.

Relief over the combined Bullfrog and Tony M properties is
about 2,250 feet. The elevation ranges from 4,550 feet above sea level at the
portal of the Tony M mine, near the southern end of the property, to 6,800 feet
above sea level over the northern end of the properties. The terrain is typical
canyon lands topography, with some areas deeply dissected by gullies and
headwalls of canyons and the rest consisting of gently sloping gravel benches
covering the northern half of the properties.

The Tony M Mine is accessed by a double entry system with two
parallel declines spaced 50 ft. apart on centres. The portals of the two 9 ft.
high by 12 ft. wide main haulageways are located on the northwesterly side of
Shootaring Canyon near the south center of Section 16 T35S R11E SLM with a sill elevation of about 4,546 ft. asl. The declines follow a minus
three percent grade (i.e., 3 ft./100 ft.) along a trend of N22°W. They generally
follow the long axis of the mineralized trend and extend approximately 10,200
ft. from the portal. The declines intersected the natural water table about
5,300 ft. from the portal. Plateau Resources Ltd. (Plateau) developed
over 18 miles of underground workings in the Tony M Mine. In 1985, when pumping
was suspended, the mine was allowed to flood. When U.S. Energy Corporation
(USEC) abandoned the Tony M property in the late 1990s, the portals to the mine
were closed and the ventilation shafts were capped as part of mine closure and
reclamation activities. Following rehabilitation work at the Tony M Mine and
re-establishment of surface facilities in 2006, Denison received operational
permits, reopened the mine and commenced mining in September 2007. Production
from exiting workings in the mine ramped up to approximately 400 tons per day by
October 2008. In November 2008, Denison announced that the operations at the
Tony M Mine would be suspended due to uranium and economic market conditions.
Denison announced the Tony M Mine will be on care and maintenance until it
determines that the mine is once again economically viable.

Surface rights held are sufficient for expected mining
operations and waste disposal areas. No milling operations are expected to occur
on the site. Therefore, no areas for tailings storage, heap leach pads or
processing plants are expected to be required.

History

The Bullfrog property was initially explored by Exxon Minerals
Company (Exxon), while the Tony M property was explored and developed
by Plateau Resources Inc. (Plateau), at that time a subsidiary of
Consumers Power Company of Michigan.

Denison acquired the Bullfrog property when it purchased
substantially all of the uranium producing assets of Energy Fuels Nuclear
(EFN) in 1997. In February 2005, Denison acquired the Tony M property,
thus bringing it under common ownership with the Bullfrog property. Energy Fuels
acquired the Bullfrog and Tony M properties on June 29, 2012, when it acquired
the US Mining Division from Denison.

Prior to 2005, all exploration, mine development, and related
activities for the two properties were conducted independently. The Bullfrog and
Tony M properties are therefore discussed separately, except where correlations
and comparisons are made.

Bullfrog Property:

Exxon conducted reconnaissance in the area in 1974 and 1975,
and then staked its first Bullfrog claims in 1975 and 1976. A first phase
drilling program conducted in 1977 resulted in the discovery of what became
known as the Southwest uranium deposit. Additional claims were subsequently
staked and drilling was continued by Exxon. Several uranium and vanadium zones
were discovered in the Southwest and Copper Bench and Indian Bench areas. With
the declining uranium markets of the early 1980s, Exxon prepared a
prefeasibility report and then discontinued development of the property.

From July 1982 to July 1983, 112 drill holes were completed by
Atlas Minerals Corp., (Atlas) under a purchase option with Exxon,
delineating the Southwest and Copper Bench deposits on approximately 100 foot
centers. From July 1983 to March 1984, a core drilling program was completed
throughout the Bullfrog property with 133 rotary drill holes to delineate the
Indian Bench deposit on approximately 200 foot centers.

In late 1992, EFN purchased the Bullfrog property from Exxon
and conducted a geologic review and internal economic analysis of the property.
In 1997, Denison became the owner of the Bullfrog property, and Energy Fuels
became owner of the Bullfrog property in June 2012.

Tony M Property:

Exploration drilling in the Shootaring Canyon area was
initiated by Plateau during 1976 in the vicinity of outcropping uranium
mineralization. In February 1977, drilling commenced in what was to become the
Tony M mine. More than 2,000 rotary drill holes totalling about one million feet
were drilled.

Development of the Tony M mine started in September 1977. By
mid-1984, nearly 17 miles of underground workings had been developed in the Tony
M mine. During development of the Tony M entryways and crosscuts, a total of
237,441 tons of material with an average grade of 0.121% U3O8 was extracted and
stockpiled.

In 1989, 30 to 40 rotary holes were drilled to delineate zones
of high grade uranium mineralization.

More recent mining activity is described under Mineral
Projects  Henry Mountains Complex  Mining Operationsbelow.

Geological Setting

The Henry Mountains Complex uranium deposits occur within the
Salt Wash Member of the Morrison Formation, located within the Colorado Plateau.
The Morrison Formation is a complex fluvial deposit of Late Jurassic age that
occupies an area of approximately 600,000 square miles, including parts of 13
western states and small portions of three Canadian provinces, far to the north
and east of the boundary of the Colorado Plateau.

The Bullfrog and Tony M deposits consist of two extensive
elongate, tabular zones containing a large concentration of mineralization.
Together the Southwest deposit of the Bullfrog property and the Tony M deposit
extend for a distance of about three miles along a north-south trend and have a
maximum width of about one-half mile. The larger Indian Bench and Copper Bench
deposits within the Bullfrog property extend about 3.5 miles along a
northwesterly trend.

Mineralization in the Bullfrog property deposits occurs over
three stratigraphic zones of the Salt Wash Member of the Morrison Formation,
while mineralization at the Tony M property occurs over four zones. The
Southwest deposit (like most of the adjacent Tony M property) occurs in the
lowermost 35 feet to 40 feet of the Salt Wash Member sandstone. Mineralization
forming the Copper Bench and Indian Bench deposits occurs between about 60 feet
and 100 feet above the base of the Salt Wash Member.

The depth below the surface to the base of the three deposits
ranges from about 475 feet (Southwest deposit) to nearly 1,100 feet in both the
Copper Bench and Indian Bench deposits.

Exploration

Surface drilling using rotary tricone technology, together with
radiometric gamma logging, was the primary exploration method used to discover
and delineate uranium on the Bullfrog and Tony M properties.

During development of the Tony M mine, Plateau also conducted
an intensive mine geology program to collect detailed information on the
occurrence of uranium, including its thickness, grade, and lateral extent. This
was done through geological mapping, together with face and rib scanning, as
well as gamma probing of short up and down holes extending to about eight feet.
Probing was also done using long-hole drilling to test target zones up to about
150 feet from mine openings. The results of this program were recorded on a
systematic set of cross sections through the Tony M mine developed at a scale of 10 feet to the inch. RPA did not have access to the
detailed information collected underground in the Tony M mine.

39

Denison carried out no work on the Bullfrog and Tony M
properties, with the exception of a review of available data and critical
evaluation, until the end of 2005 when certain activities including underground
reconnaissance and permitting were initiated. See Operations  U.S. Mines 
Henry Mountains Complexabove.

Energy Fuels has carried out no exploration work on the
property since acquisition in June 2012.

Mineralization

The uranium/vanadium mineralization in the Henry Mountains
Complex is similar to ores observed elsewhere in the Colorado Plateau. It occurs
as intragranular disseminations within the fluvial sand facies of the Salt Wash
Member. It also forms coatings on sand grains and organic associated masses.
Coffinite is the dominant primary uranium mineral in the mineralized horizons,
with uraninite occurring in only trace amounts.

Vanadium occurs as montroseite (hydrous vanadium oxide) and
vanadium chlorite in primary mineralized zones located below the water table,
(i.e., the northern portion of the Tony M property). Above the water table to
the south, vanadium chlorite is absent, while montroseite and a suite of
secondary uranium/vanadium minerals are present.

In the southern Henry Basin, including the Henry Mountains
Complex Property, the Salt Wash Member ranges from 400 ft. to 510 ft. thick. In
the northern part of the Tony M deposit, core hole 91-8-14c intersected 444 ft.
of the Salt Wash Member. The lower Salt Wash sandstones are finer grained, while
the upper Salt Wash sandstones consist of more coarse grained clastics. The
lower Salt Wash is approximately 150 ft. thick in the Property area, thinning
and becoming less sandy northward from the project area. Sandstones comprise 80%
of the sequence, with siltstones and mudstones making up the remainder.
Significant uranium mineralization occurs only in this lower unit. Figure 7-4
shows a representative stratigraphic section from the Property. The Tony M
deposit is developed in the lowermost 35 ft. to 40 ft. of the Salt Wash, while
mineralization in the Southwest deposit reaches 60 ft. above the Salt Wash
Member base. The sand sequence occurring in the Tony M deposit also occurs in
the Southwest deposit. Mineralization of the Frank M deposit occurs between 60
ft. and 100 ft. above the base of the Salt Wash Member and is correlative with
the Copper BenchIndian Bench deposit. The lower 100 ft. of the Salt Wash Member
have been subdivided into an upper and a lower unit, and each of these subunits,
in turn, have been subdivided into upper, middle, and lower horizons. The Tony
MSouthwest deposit occurs in the lower, middle, and upper mineralized horizons
of the lower 40 ft. thick sand unit. Each of the horizons is 10 ft. to 15 ft.
thick. The analysis of the mineralization, however, shows that a high percentage
of the mineralization occurs within two units designated in the Henry Mountains
Technical Report as the Lower Lower and the Upper Lower units, with the Middle
Lower unit included in the Upper Lower unit. The Copper BenchIndian Bench
deposit occurs in the upper, middle, and lower horizons of the Upper unit (i.e.,
60 ft. to 100 ft. above the base).

The Henry Mountains Complex vanadium-uranium deposits consist
of two extensive elongate, tabular zones containing a large concentration of
mineralization. The Tony MSouthwest deposit extends for a distance of
approximately 2.5 miles along a north-south trend and has a maximum width of
about 3,000 ft. The larger Copper Bench-Indian Bench deposit extends
approximately 3.5 miles along a northwesterly trend to the northeast of the Tony
MSouthwest deposit. More specifically, the mineralization making up the
indicated and inferred resources documented in this report form high grade zones
within the two mineralized trends. The Tony MSouthwest deposit occurs within an
arcuate zone over a north-south length of about 15,000 ft. and a width ranging from 1,000 ft.
to 3,000 ft.. The Copper Bench-Indian Bench deposit extends northwesterly over a
length of approximately 15,000 ft. and a width of 1,000 ft. to 2,500 ft.
Mineralization occurs in a series of three individual stratiform layers included
within a 30 ft. to 62 ft. thick sandstone interval. Mineralization in the Tony M
deposit occurs over three stratigraphic zones of the Salt Wash Member of the
Morrison Formation, when a minor zone in the Tidwell is included in the lower
zone. The Tony M-Southwest deposit occurs in the lowermost 35 ft. to 62 ft. of
the Salt Wash Member sandstone. Mineralization within the Upper Lower unit is
offset to the east as compared to mineralization in the Lower unit.
Mineralization forming the Copper BenchIndian Bench deposit occurs between 60
ft. and 100 ft. above the base of the Salt Wash Member.

Drilling

The mineralization on the Property is approximately horizontal,
and all of the drilling was vertical. Deviation surveys were conducted on most
drill holes in the Southwest deposit, providing an indication of how far the
holes have drifted from vertical. The vertical holes provide a reliable estimate
of the thickness of the deposits.

Bullfrog Property:

Most of the drilling done on the Southwest, Copper Bench, and
Indian Bench deposits on the Bullfrog property was conducted by rotary drilling
using a tricone bit. Additional drilling was done to collect core samples.

The Indian Bench deposit is delineated by drilling on
approximately 200 foot centers, while the Southwest and Copper Bench deposits
were drilled on 100 foot centers. In some areas, the rugged terrain made access
difficult, resulting in an irregular drill pattern. A total of 2,232 drill holes
were completed on the Bullfrog property.

The mineralization is approximately horizontal on the Bullfrog
property, so vertical holes provide a reliable estimate of the thickness of the
deposits.

Tony M Property:

In February 1977, drilling commenced in what was to become the
Tony M deposit. Plateau drilled more than 2,000 rotary drill holes totalling
about 1.0 million feet. The holes were drilled using rotary tricone technology.
The rugged terrain over much of the Tony M property made drilling access
difficult, resulting in an irregular drill pattern. The drilling includes 24
core holes. The core holes provided samples of the mineralized zone for chemical
and amenability testing and to determine geologic and engineering properties of
the mineralized zone.

Records indicate that a total of 81 core holes were drilled in
the Southwest, Copper Bench, and Indian Bench deposits, while 25 core holes were
drilled in the vicinity of the Tony M deposit Drilling on the Tony M area
includes 24 core holes completed by Plateau and one core hole completed by
NFS/BP Exploration Inc. Of the 25 holes, only 11 are located within the
mineralized area comprising the Tony M deposit. The core holes provided samples
of the mineralized zone for chemical and amenability testing, as well as flow
sheet design for the Ticaboo uranium processing facility (or mill). The samples
were also used to determine geologic and engineering properties of the
mineralized zone. RPA did not have access to core for the Tony M deposit. Energy
Fuels, Denison, and predecessor IUC carried out no surface drilling on the
properties.

Sampling and Analysis

Bullfrog Property:

Downhole gamma logging of surface holes was done on the
Bullfrog property. Standard logging suites included radiometric gamma,
resistivity and self potential measurements, supplemented by neutron-neutron
surveys for dry holes. Deviation surveys were conducted for most of the holes.

Assays of samples from core drilling were collected by company
geologists and submitted to various commercial labs for analysis. Results of
these analyses were compared to eU3O8 values from gamma logs to evaluate
radiometric equilibrium, logging tool performance, and validity of gamma
logging.

Mineral Resource estimates for the Bullfrog property are based
on the eU3O8% gamma log conversionvalues used to identify the
mineralized zone, its thickness and calculate an average grade. The procedures
implemented to identify the minimum grade and cut-off GT product for Mineral
Resource estimation are described below under the heading Cut-Off Grade and
Mining Considerations.

Tony M Property:

The same suite of logging surveys and procedures as employed at
the Bullfrog property were conducted for the Tony M property. Assays of samples
from core drilling were collected and submitted for analysis. Confirmation
assays of chemical U3O8% were completed on drill core samples for comparison and
calibration with eU3O8% values from gamma logging.

Status of Chemical Equilibrium of Uranium

Bullfrog Property:

Exxon conducted analyses of samples from core drilling in the
Southwest and Copper Bench deposits and found that the radioactive
disequilibrium of potentially economic grade intercepts in cores, measured as
the ratio of chemical U3O8% to log radiometric equivalent (eU3O8%), varied from
0.80 to 1.35 and averaged 1.06, close to the equilibrium value of 1.0. Other
investigations had identified no significant disequilibrium problem.

Tony M Property:

Plateau conducted an extensive investigation of the state of
chemical disequilibrium of uranium in the Tony M deposit. In 1989, a previous
operator reported that an analysis of results from 1,763 samples, including
1,137 composite samples collected from buggies coming from the Tony M mine, was
completed in 1983. Based on that analysis, it was concluded: (i) the state of
disequilibrium varies from location to location within the deposit; (ii) with
the exception of one small area in the southern part of the deposit, the
equilibrium factor is positive; (iii) low grade material with less than
0.06% U3O8 is depleted in uranium; and (iv) higher grade material containing more
than 0.06% U3O8 is enriched in uranium.

Roscoe Postle Associates Inc. (RPA) is of the opinion
that based on the information available, the original gamma log data and
subsequent conversion to eU3O8% values are reliable but slightly conservative
estimates of the uranium U3O8% grade. Furthermore, there is no evidence that
radiometric disequilibrium would be expected to negatively affect the uranium
resource estimates of the Henry Mountains Complex.

Data Verification

Based on its review of the grade and thickness of uranium
mineralization determined in the original gamma logs and a comparison with the
computer generated GT composites, RPA is of the opinion that the original gamma
log data and subsequent conversion to eU3O8 values are reliable. Furthermore,
RPA reviewed the chemical analyses of core from diamond drill holes
from the Bullfrog property and is of the opinion that the gamma logging results
for the Bullfrog property provide a reliable, but conservative, estimate of the
uranium content. The review suggests that the mineral resource estimate may
underestimate the uranium content of the Bullfrog property by up to about 5%.

42

Security of Samples

Procedures followed during exploration were well documented and
at the time followed best practices and standards of companies participating in
uranium exploration and development. Onsite collection of the downhole gamma
data and onsite data conversion limit the possibility of sample contamination or
tampering.

Mineral Resource Estimation

In the Henry Mountains Technical Report, RPA audited the 1993
EFN mineral resource estimate of the Copper Bench and Indian Bench deposits on
the Bullfrog property and the Southwest deposit on the Tony M property, accepted
them as a current Mineral Resource estimate and classified them as Indicated
Mineral Resources and Inferred Mineral Resources in accordance with CIM
definitions.

The basis for this Mineral Resource estimation is the gamma
logs from 1,801 rotary drill holes located on the Southwest, Copper Bench and
Indian Bench deposits. This represents about 80% of the 2,232 total holes
drilled on these deposits. A total of 81 core holes were drilled to recover
samples for chemical and geologic analysis and to establish stratigraphic
relationships. All of the drilling and analyses were conducted by past owners,
prior to Energy Fuels tenure. See Mineral Projects  Henry Mountains
Complex  Drillingabove.

The grades of the mineralized zones were calculated on a
polygonal block-by-block basis. The pounds of eU3O8 for each polygon were then
tabulated along with the area and calculated volume for each block. The total
number of tons and pounds of eU3O8 contained in the blocks were summed to
provide a total inventory for each of the three deposits. Average grades for
each deposit were estimated from the grades of the drill hole intersections used
in the Mineral Resource estimate weighted by tonnage.

In the preparation of the Henry Mountains Technical Report, RPA
audited the Mineral Resource estimates of the Tony M and Southwest deposits
prepared by Denison using the contour method in 2008 and accepted them as a
current Mineral Resource estimate, and has classified them as Indicated and
Inferred Mineral Resources in accordance with CIM definitions.

The results of 1,671 drill holes were used to prepare the
Mineral Resource estimates for the Tony M and the Southwest deposits. A total of
32 core holes were drilled to recover samples for chemical and geologic analysis
and to establish a stratigraphic relationship. All of the drilling and analyses
were conducted by past owners, prior to Energy Fuels tenure. See Mineral
Projects  Henry Mountains Complex  Drillingabove.

Notes:(1)
    The Mineral Resource estimates comply with the
      requirements of NI 43-101 and the classifications comply with CIM
      definition standards.(2)
    The Tony M and Southwest Mineral Resources were estimated
      at a cut-off grade of 0.10% eU3O8over a minimum
      thickness of 2 feet and a minimum GT of 0.2 feet-%.(3)
    The Indian Bench and Copper Bench Mineral Resources were
      estimated at a cut-off grade of 0.20% eU3O8, a
      minimum thickness of 4 feet and a minimum GT of 0.8 feet-% that does not
      include any intervals with less than a 0.5 foot intercept of 0.08%
      U3O8.


Cut-Off Grade and Mining Considerations

The selection of a 0.20% eU3O8 cut-off for the Copper Bench and
Indian Bench was made by RPA based on evaluations of current mining and
processing costs made by both Denison and other operators in the region.

The 0.20% eU3O8 cut-off maximizes the tonnage of higher grade
mineralization while maintaining strong positive value. Based on the extensive
review of the drilling, RPA noted that lowering the cut-off criteria will
increase total tonnage by increasing the number of drill hole intercepts meeting
the cut-off, while also increasing the apparent continuity of mineralization
between adjacent drill holes.

For the Tony M and Southwest deposits, Energy Fuels established
minimum grade, thickness and GT parameters based on conventional Colorado
Plateau mining practices and recent operating costs at the Tony M mine.

As an initial step for compositing the drill hole assays,
minimum grades of 0.10%, 0.08%, 0.05% and 0.03% eU3O8 were used over a minimum
thickness of two feet, with a two foot minimum for exclusion of waste intervals.
This resulted in minimum GT values of 0.20 feet-%, 0.16 feet-%, 0.10 feet-% and
0.06 feet-%, respectively. The two-foot thicknesses are based on the mining
technique of split shooting, which is commonly used in the Colorado Plateau
District. For inclusion of blocks in the Mineral Resource estimate, Energy Fuels
used a cut-off grade of 0.10% eU3O8.

Upon receipt of the initial exploration permit, the previous
operator engaged Dynatec Mining Corporation (Dynatec) as its mine
contractor for the Tony M operation. In May 2007, Dynatec began limited
rehabilitation work on the existing Tony M workings.

Permitting

Bullfrog Property:

The Company is currently preparing mine plans for permitting
purposes and plans to initiate baseline studies of the property in the spring of
2014. The approved permitting schedule is based on having the BLM Plan of
Operations (PO), the UDOGM Large Mine Notice of Intent (NOI),
and other required state and federal permit applications submitted in
4th Quarter 2014.

Tony M Property:

The original Tony M mine permit was allowed to lapse.
Subsequently, the previous operator filed for exploration permits with UDOGM and
the BLM. These permits were granted by UDOGM and the BLM on December 2, 2005 and
March 6, 2006, respectively, which enabled the previous operator to regain
access, inspect and begin rehabilitation of the Tony M underground workings. The
previous operator also began the permitting process for the Tony M mine. The
permit application was submitted in November 2006 and a Record of Decision
(RoD) and approved Plan of Operations were received in September 2007.

The PO was challenged by the Center for Water Advocacy and the
Utah Chapter of the Sierra Club, which requested a Utah State BLM Director
Review and a stay of the decision approving the Final PO for the Tony M mine. On
November 21, 2007, the BLM State Director issued a decision vacating the
previously issued permit and remanded the case to the Field Office in order that
the Environmental Assessment (EA) for the Tony M Mine PO could be
amended and a new RoD issued. As a result of this decision to vacate and renew,
the request for stay was considered moot. The new decision was issued by the BLM
on November 23, 2007 approving the PO for the mine. The new decision was once
again appealed by the Center for Water Advocacy and the Utah Chapter of the
Sierra Club. The Utah State Director issued a decision denying the appeal and
upholding the PO on February 19, 2008.

Permit applications for a Phase 2 expansion were submitted to
the BLM and UDOGM in 3rd Quarter 2008, but the previous operator
subsequently requested that agency review of the applications be deferred given
the market conditions at that time. The Company is planning to re-submit the
applications in 2014, but for a much smaller expansion plan consisting of
additional ventilation shafts, associated access roads, and expansion of the
evaporation pond.

Mining Method

With the receipt of the operating permit in September 2007,
Dynatec shifted from rehabilitation work to mining of the Tony M deposit. As of
the end of 2007, 9,368 tons of ore grading 0.10%U3O8
had beenshipped to the White Mesa Mill from the Tony M mine. The reason
for the initial low grade was that it was related to development work to access
the higher grade deposits.

In addition to re-opening the mine, the previous operator also
constructed a number of surface facilities including a power generation station,
compressor station, fuel storage facilities, maintenance building, offices and
dry storage. An evaporation pond, which was originally constructed when the Tony
M mine was in operation in the 1980s, and which is used for storage and
evaporation of mine water, was reconstructed to allow for dewatering of the
mine. All surface facilities are well-maintained and in good condition.

45

---

In 2008, 87,421 tons grading 0.15% U3O8 were shipped to the
White Mesa Mill, as well as 64,755 tons of ore from the historic stockpiles,
grading 0.11% U3O8. In November 2008, the previous operator announced that
operations at the Tony M mine were being placed on temporary standby due to high
operating costs and the weakening of the uranium spot price. Shipping of ore
from the historic stockpiles continued after the mine was placed on standby.

In March 2009, shipping of the historic ore stockpile to the
White Mesa Mill was completed with 29,737 tons of ore grading
0.11% U3O8, shipped.The vanadium grades were
too low to be recovered under the market conditions at that time.

The mine remains on care and maintenance.

Metallurgical Process

Metallurgical testing included leach amenability studies,
settling, and filtration tests. Drill core from the Bullfrog deposits was tested
by Atlas in 1983 to determine metallurgical parameters. Amenability results for
a strong acid leach indicated overall recoveries of 99% U3O8 and 90% V2O5.
Additional testing of a mild acid leach and an alkaline leach gave recoveries of
97% U3O8and 40% V2O5for both. Acid consumption for the strong acid leach was 350
pounds per ton. In 1982, the Shootaring Canyon mill processed some 27,000 tons
of mineralized material from the Tony M Mine, but details were not available to
RPA. A USNRC report lists a recovery of 90% for the milling operation. From
November 2007 to December 2008, a total of 162,384 tons at 0.131% eU3O8containing
429,112 pounds U3O8were trucked to the White Mesa Mill at Blanding, Utah, for
processing. Of this material, 90,025 tons at 0.165% eU3O8(297,465 pounds) were
extracted by Denison from the Tony M Mine and 72,359 tons at 0.091% eU3O8(131,647
pounds) came from stockpiled material mined by previous operators.

The White Mesa Mill is located six miles south of Blanding in
southeastern Utah. Its construction by EFNI was based on the anticipated
reopening of many small low-grade mines on the Colorado Plateau, and the mill
was designed to treat 2,000 tons of ore per day. The mill has operated at rates
in excess of the 2,000 tons per day design rate. Construction commenced in June
1979 and was completed in May 1980. The mill has been modified to treat higher
grade ores from the Arizona Strip, as well as the common Colorado Plateau ores.
Processing of Arizona Strip ores is typically at a lower rate of throughput than
for the Colorado Plateau ores. The basic mill process is a sulphuric acid leach
with solvent extraction recovery of uranium and vanadium. Run-of-mine ore is
reduced to minus 28 mesh in a six-foot by 18-ft. diameter semiautogenous
grinding (SAG) mill. Leaching of the ore is accomplished in two stages:
a pre-leach and a hot acid leach. The first, or pre-leach, circuit, consisting
of two mechanically agitated tanks, utilizes pregnant (high-grade) strong acid
solution from the countercurrent decantation (CCD) circuit which serves
both to initiate the leaching process and to neutralize excess acid. The
pre-leach circuit discharges to a 125-ft. thickener where the underflow solids
are pumped to the second stage leach and the overflow solution is pumped to
clarification, filtration, and solvent extraction circuits. A hot strong acid
leach is used in the second stage leach unit, which consists of seven
mechanically agitated tanks having a retention time of 24 hours. Free acid is
controlled at 70 grams per litre and the temperature is maintained at 75oC.
Leached pulp is washed and thickened in the CCD circuit, which consists of eight
high capacity thickeners. Underflow from the final thickener at 50% solids is
discharged to the tailings area. Overflow from the first thickener (pregnant
solution) is returned to the pre-leach tanks. The solvent extraction (SX)
circuit consists of four extraction stages in which uranium in mpregnant
solution is transferred to the organic phase, a mixture consisting of 2.5%
amine, 2.5% isodeconal, and 95% kerosene. Loaded organic is pumped to six stages
of stripping by a 1.5 molar sodium chloride solution, and thence to a continuous
ammonia precipitation circuit. Precipitated uranium is settled, thickened,
centrifuged, and dried at 1,200F. The final product at about 95% U3O8is packed
into 55-gallon drums for shipment

Roca Honda Project

Except as noted, the following description of the Roca Honda
Project is based on a technical report entitled "Technical Report on the Roca
Honda Project, McKinley County, New Mexico, U.S.A." dated August 6, 2012,
prepared by Patti Nakai-Lajoie, P.Geo., Robert Michaud, P.Eng., Stuart Collins,
P.E., and Roderick Smith, P.Eng., all of Roscoe Postle Associates (RPA)
in accordance with NI 43-101 (the Roca Honda Technical Report). The
technical report includes an updated mineral resource estimate and the results
of a Preliminary Economic Assessment ("PEA") for the uranium resources
outlined to date at the Roca Honda Project in New Mexico. Each of the authors of
the Roca Honda Technical Report is a qualified person and is independent of
the Company within the meaning of NI 43-101.

The Roca Honda Project was acquired by the Company on August
29, 2013 as a result of the acquisition of Strathmore by Energy Fuels. See
General Development of the Business  Significant Acquisitions  Acquisition
of Strathmore Minerals Corp. above.



Property Description and Location

The Roca Honda Project is a 60%-40% joint venture among Energy
Fuels and affiliates of Sumitomo Corporation of Japan (Sumitomo). The
project is held in an entity called Roca Honda Resources, LLC, a Delaware
limited liability company (RHR), of which Energy Fuels indirect
wholly-owned subsidiary Strathmore Resources (US) Ltd. (Strathmore US)
holds a 60% interest and Sumitomo holds a 40% interest. RHR was established on
July 26, 2007, when Strathmore Minerals Corp. (Strathmore) formed a
limited liability company with Sumitomo and transferred the Roca Honda property
into RHR.

The Roca Honda Project is located approximately three miles
northwest of the community of San Mateo, New Mexico, near the southern boundary
of McKinley County and approximately 22 road miles northeast of Grants, New
Mexico. The property is located in the east part of the Ambrosia Lake
sub-district of the Grants Mineral Belt in northwest New Mexico and comprises
nearly all of Sections 9, 10, 16 and a sliver of Section 11, all in Township 13
North, Range 8 West (T13N-R8W), New Mexico Principal Meridian.

The Roca Honda property covers an area of 1,886.5 acres,
including 63 unpatented lode mining claims in Sections 9, 10 and 11 covering an
area of 1,248.5 acres on and a New Mexico State General Mining Lease, as amended
(the Roca Honda State Lease) located in Section 16. Strathmore acquired
the mining claims on March 12, 2004, from Rio Algom Mining LLC (Rio
Algom), a successor to Kerr-McGee Corporation (Kerr-McGee), which
staked the claims in 1965. The claims have been continuously maintained since
1965. Mining claims RH 252, RH 279, RH 306, and RH 333, located in the southern
portion of Section 10, partially overlap the northern part of Section 15, which
is privately-owned land. The overlapping portion of these claims are not
valid. However, the overlapping portions of the claims do not constitute any
part of the Roca Honda Project or its Mineral Resources. The Roca Honda property
boundary only extends to the Section 15 boundary.

47

---

The 63 unpatented, contiguous mining claims, covering an area
of 1,248.5 acres, are located on Sections 9, 10, and 11, which are federally
owned lands within the Cibola National Forest administered by the US Forest
Service (USFS). The claims are listed in the U.S. Bureau of Land
Management (BLM) Mining Claim Geographic Index Report (LR2000)
with a location date of June 29 and 30, 1965. The latest assessment year is 2013
and the LR2000 shows the claims as Active. Holding costs for the 63 claims
include a claim maintenance fee of US$140.00 per claim payable to the BLM before
September 1 of each calendar year and the recording of an affidavit and Notice
of Intent to Hold with the McKinley County, New Mexico Clerk, costing
approximately $10.00 per claim. All Roca Honda property holdings are in good
standing. Unpatented mining claims expire annually, but are subject to
indefinite annual renewal by filing the appropriate documents and paying the
fees as described above.

The Roca Honda State Lease (No. HG-0036-002) is located on
Section 16 and covers an area of 638 acres. The surface of Section 16 is leased
to Fernandez Company, Ltd. (Fernandez) as rangeland for grazing. The
area covered by the Fernandez lease is also referred to as Lee Ranch. The
lease has a primary, secondary, tertiary, and quaternary term, each with rentals
to be paid in advance. The lease is currently in the tertiary term of five years
(expiring on November 29, 2014). If minerals are not produced or mined during
the tertiary term, the lease may be extended by the lessee for a quaternary term
of five years (expiring on November 29, 2019) and for so long as minerals are
produced or mined. The lease contains a 5% gross returns royalty to the State of
New Mexico, less smelting or reduction costs, for production of uranium, which
is designated as a special mineral in the lease. If there is no production or
mining during the primary, secondary or tertiary terms, then advance royalties
are required during the quaternary term, in addition to annual rentals, as
follows: US$10 per acre in the 11th year (November 30, 2014 to
November 29, 2015), and increasing by US$10 per acre per year for the next four
years of the quaternary term until the lease expires on November 29, 2019.

There is a New Mexico mining royalty payable on the value of
mineral production for New Mexico state leases. The royalty is based upon the
operating cash flow less a development allowance, depreciation and a processing
allowance. New Mexico mining and private royalties on value of minerals
extracted includes Landowner Access (1%), Section 9 Gross Royalty (1%), and
Section 16 New Mexico State Lease Royalty (5%).

There are no outstanding environmental liabilities to which the
project is subject.

Old drill roads were previously established across the
property, and an electrical line transects the northern half of Section 16 in
the project area. The line continues on the west side of the project area into
Section 17, where it terminates, and on the east side of Section 16 through the
northwest quarter of Section 15 and along the southern section boundary of
Section 10. Three monitor water wells were drilled by RHR in 2007, and are
located on Section 16.

Please see Mineralization section below for the
location of all known mineralized zones and mineral resources. Please see
Permitting section below for the current status of permitting and
approvals for the project.

Accessibility, Climate, Local Resources, Infrastructure and
Physiography

The Roca Honda Project is currently accessed by public roads,
highways and across private land held by Fernandez. It is located approximately
17 air miles and 22 road miles northeast of Grants, New Mexico.

48

---

The southern portion of the project, on Section 16, can be
reached by traveling north from Milan on New Mexico State Highway 605 toward the
town of San Mateo to mile marker 18 and then north on a public gravel road.
Access rights from Highway 605 onto Section 16 are subject to negotiations with
the surface lease-holder, Fernandez. The previous access agreement expired on
December 31, 2012, but a long-term access agreement across the Fernandez
properties is in process, and the landowner is currently allowing access on a
limited basis. The north part of the project can be reached by traveling 23.5
miles from Milan, New Mexico, on paved public Highway 605, and then west on US
Forest Service roads to the southeast corner of Section 10. There are numerous
drill roads that provide access to different portions of Sections 9 and 10, many
of which will require maintenance. Surface rights held are sufficient for
expected mining operations and waste disposal areas. No milling operations are
expected to occur on the site. Therefore, no areas for tailings storage, heap
leach pads or processing plants are expected to be required.

The climate in the Roca Honda project area may be classified as
arid to semi-arid continental, characterized by cool, dry winters, and warm, dry
summers. On average, the Roca Honda property receives approximately 11 inches of
precipitation annually, most of which occurs during thunderstorms in July and
August. Winter is the driest season with an average of approximately 13 inches
of snow falling annually, mostly during December through February. Grants, New
Mexico has an annual average temperature of 50°F, with an average summer high of
87°F and low of 52°F, and average winter high of 47°F and low of 18°F.
Year-round operations are expected.

The community of Grants, New Mexico, located in Cibola County,
is the largest community near the Roca Honda Project. As of the 2010 census,
there are 8,772 people residing in Grants, where supplies can be obtained and
personnel experienced in open pit and underground mining, construction and
mineral processing are available.

There is no infrastructure on the Roca Honda property other
than old drill roads and an electrical line that transects the northern half of
Section 16. A monitoring well network of three wells, completed in the Westwater
Canyon Member of the Morrison Formation, was installed in 2007 and 2008 by RHR.
Other items installed by RHR include a permanent electrical weather station and
a high volume TSP and PM10 air samplers. Three, dry man-made impoundments are
also located on Section 16. More than 400 historic drill exploration holes were
completed on the property from the late 1960s to the early 1980s.

The Roca Honda Project area is sparsely populated, rural and
largely undeveloped. The predominant land uses include low density grazing and
cultivation, and recreational activities such as hiking, sightseeing, and
seasonal hunting. The Roca Honda property has moderately rough topography in
Sections 9 and 10 and consists of shaly slopes below ledge-forming sandstone
beds, as mesas, that dip 7° to 11° northeast. Elevations range from 7,100 feet
to 7,800 feet. Section 9 consists mostly of steep slopes in the west and south,
with a large sandstone mesa in the north central part. Section 10 consists
mostly of the dip-slope of a sandstone bed that dips from 8° to 11° east.
Section 16 has less topographic relief, with elevations ranging from 7,100 to
7,300 feet and easterly dipping slopes. Vegetation in the Roca Honda project
area consists of grasses, piñon pine and juniper trees.

History

Kerr-McGee staked the Roca Honda unpatented mining claims in
Sections 9 and 10 on June 29-30, 1965. Kerr-McGee, its subsidiaries, and its
successor-in-interest, Rio Algom, held the claims until the property was
acquired by Strathmore on March 12, 2004. Section 16, on which the Roca Honda
State Lease sits, is owned by the State of New Mexico. State mining leases have
been issued to various companies over the years; including Rare Metals
Corporation in the 1950s who performed the first drilling on Section 16,
Western Nuclear which held leases from 1968 to 1971 and 1979-1994. Quivery
Mining Company, a wholly-owned subsidiary of Kerr-McGee, acquired lease no.
Q-1414 in 1990 with a 15-year term. However, Kerr-McGee cancelled this lease
prior to expiration in 2000. David Miller, the former CEO of Strathmore,
acquired the current lease in November 2004 and assigned it to Strathmore.
Currently, the unpatented mining claims and the lease are held by RHR.

Kerr-McGee performed a rotary drill hole exploration program
beginning in 1966. The drill holes were taken through the Westwater Canyon
Member and several feet into the underlying Recapture Member (non-host). In
Section 9, the first drill hole was completed in 1966, and discovery was made on
August 2, 1970, encountering high-grade mineralization. From that time to
September 1977, 184 drill holes were completed in Section 9. From 1979 to 1982,
three additional drill holes were completed. A total of 388,849 feet of drilling
was completed in these 187 holes.

In Section 10, the first hole was completed in 1967, and
discovery was made on March 19, 1974, encountering high-grade mineralization.
From that time to 1977 170 drill holes were completed. Between 1979 and 1985,
five additional holes were completed. A total of 450,838 feet of drilling was
completed in these 175 holes.

In Section 16, the first drilling was completed in the 1950s
by Rare Metals, which drilled 13 holes. Subsequently, Western Nuclear began a
drill program in 1968 and their second drill hole intercepted high-grade uranium
mineralization. From 1968 to 1970, Western Nuclear drilled 63 holes totaling
121,164 feet. A number of resource estimates were prepared for the property over
the years, each of which are detailed in the NI 43-101 report for the Roca Honda
project.

In January 1978, Kerr-McGee proposed a Roca Honda mine plan
using a shaft with a maximum depth of 2,750 feet. The mine plan assumed that
excess water would be a major factor in underground mining. A 14-foot diameter
shaft was sunk to a depth of approximately 1,700 feet on Section 17 (adjacent to
Section 16). Section 17 is currently held by Uranium Resources Inc.
(URI) That shaft was abandoned prior to mining due to falling uranium
prices.\

No ore production has previously occurred on the property.

Geologic Setting

The Roca Honda Project area is located in the southeast part of
the Ambrosia Lake sub-district of the Grants uranium district and is near the
boundary of the Chaco slope and the Acoma sag tectonic features. This
sub-district is in the southeastern part of the Colorado Plateau physiographic
province and is mostly on the south flank of the San Juan Basin. Less than five
miles to the east and south of the project area, Neogene volcanic rocks of the
Mt. Taylor volcanic field cap Horace Mesa and Mesa Chivato.

Rocks exposed in the Ambrosia Lake sub-district include marine
and non-marine sediments of Late Cretaceous age, unconformably overlying the
uranium-bearing Upper Jurassic Morrison Formation. The uppermost sequence of
conformable strata consists of the Mesaverde Group, Mancos Shale, and Dakota
Sandstone. All rocks that outcrop at the Roca Honda project area are of late
Cretaceous age. Geologic structures on the property are associated with regional
reformation that occurred during the late Cretaceous, following deposition of
the geologic strata seen on the property. There is no evidence of recent
activity. The primary structures are high-angle, north to northeast trending
normal faults that cut across the western portion of Sections 9 and 16, with no
major faults evident on Section 10.

The uranium found on the Roca Honda project is contained in
five sandstone units of the Westwater Canyon Member (Jmw). Zones of
mineralization vary from approximately one foot to 32 feet thick, 100 feet to
600 feet wide, and 100 feet to 2,000 feet long. Uranium mineralization in the
project area trends west-northwest, consistent with trends of the fluvial sandstone
structures of the Westwater Canyon Member, and the general trend of
mineralization across the Ambrosia Lake sub-district.

50

---

Uranium mineralization consists of unidentifiable
organic-uranium oxide complexes. The uranium in the project area is dark gray to
black in color and is found at depths of approximately 1,650 to 2,600 feet below
the surface. Admixed and associated with the uranium are enriched amounts of
vanadium, molybdenum, copper, selenium, and arsenic, in order of decreasing
abundance. Primary mineralization pre-dates, and is not related to, present
structural features. There is a possibility of some redistribution and stack ore
along faults; however, it appears that most of the Roca Honda mineralization is
primary. Paleochannels that contain quartz-rich, arkosic, fluvial sandstones are
the primary mineralization control associated with his trend. Previous mining
operations within the immediate area suggest that faults in the Roca Honda area
associated with the San Mateo fault zone post-date the emplacement of uranium.
Therefore, it can be expected that mineralized zones in the Roca Honda area are
offset by faults.

Primary mineralization deposits are generally irregular,
tabular, flat-lying bodies elongated along an east to southeast direction,
ranging from thin pods a few feet in thickness and length to bodies several tens
of hundreds of feet long. Primary mineralization in the Ambrosia Lake
sub-district consists mostly of uranium-enriched humic matter that coats sand
grains and impregnates the sandstone, imparting a dark color to the rock.

Exploration

Historical exploration consisted of drilling, as the uranium
deposits in the Ambrosia Lake and Roca Honda have no surface expression and
require drilling for discovery and delineation. There are no surface methods for
detecting uranium deposits at the depths exhibited on the Roca Honda property.

RHR has conducted additional exploration work, including:
reinterpretation of historic drill logs during 2006 and 2007; preparation of a
baseline data report in 2009 (revised in 2011) to support a mine permit
application (including archaeological, biological, air, radiometric, soil,
meteorological, and water surveys); installation of monitor wells and pump
testing; aerial surveys; groundwater flow modeling; geotechnical survey, and the
completion of a drill hole at the Section 16 shaft location.

Exploration potential exists in Section 16, as the potential
quantity and grade of mineralization are conceptual in nature. There has been
insufficient exploration in Section 16 to define a Mineral Resource, and it is
uncertain if further exploration will result in the reclassification of the
exploration target as a Mineral Resource.

A few widely spaced holes in the central part of Section 16
contain mineralization in the A and B1 sands, above 0.1% U3O8 across a minimum
thickness of six feet. Six mineralized intersections are located in the A sand, and appear to align along an approximate 100° azimuth
trend, parallel to the A zone trend identified in the north part of Section 16.
This includes 0.56% U3O8 over a 15-ft thickness, intersected by the recent RHR
hole, S2-Jmw-CH-07. Although this an isolated intersection in the central part
of Section 16, potential for additional mineralization exists along the
approximated trend. Potential also exists eastward, where Hole 16055 intersected
0.145% U3O8 over an 11-ft thickness. Hole 16058 is another isolated hole in the
central part of Section 16, which intersected 0.136% U3O8 over a 15-ft thickness
in the B1 sand. Potential exists for additional mineralization east and west of
this intersection, and parallel to the adjacent potential A zone trend.
Available data from Section 17 (west of Section 16) and Section 15 (east of
Section 16), indicate this trend extends beyond Section 16 into each of these
sections. Based on maximum lengths and widths determined from existing A and B1
zone mineralization models, a tonnage factor of 15-ft3/st, and an average 6-ft
thickness, total exploration potential is estimated at 600,000 tons to 800,000
tons at 0.30% to 0.40% U3O8, containing approximately four million pounds U3O8.
Exploration potential is located in Section 16. The potential quantity and
grade of the central part of Section 16 are conceptual in nature. There has been
insufficient exploration to define a Mineral Resource, and it is uncertain if
further exploration will result in the reclassification of the exploration
target as a Mineral Resource.

Drilling

Drilling on the Roca Honda project has been conducted in phases
by Rare Metals, Kerr-McGee, Western Nuclear and RHR from 1966 to 2011, and
consists of 443 drill holes totaling 970,954 feet. A drill summary table by
section is included below.

- Section 9: Kerr-McGee (1966 to 1982), 187 holes, 388,849 feet
- Section 10: Kerr-McGee (1967 to 1985), 175 holes, 450,838 feet
- Section 16: Western Nuclear (1968 to 1970), 63 holes, 121,164 feet
- Section 16: Rare Metals (1950s), 13 holes, unknown footage
- Section 16: RHR (2007), 4 holes, 8,050 feet
- Section 16: RHR (2011), 1 hole, 2,053 feet

Previous drilling on the Roca Honda property was performed by
Kerr-McGee on Sections 9 and 10, and by Rare Metals and Western Nuclear on
Section 16 using rotary mud drilling with truck-mounted drills contracted by
local drilling companies. Kerr-McGee files contain detailed records of drilling
results. Drill logs are available for three holes completed by Rare Metals in
the 1950s. For the Western Nuclear drilling, complete files of drill summary
sheets containing intercepted grade, thickness, zone, and alteration (oxidation)
for each mineralized interval is available.

Kerr-McGee files contain detailed records of probe truck
equipment characteristics for each logging unit, including truck number, probe
number, crystal size, dates of use, k factors, calibration tests, and resulting
factors. Each gamma log contains a footer with a calibration run and a header
sheet with the rerun factors and probe unit number. An initial program of 13
drill holes was completed by Rare Metals in the 1950s on Section 16. The name of
the contract drilling company is not available; however, records indicate
Century Geophysical conducted geophysical logging of holes. Drill logs are
available for three holes, however, recorded collar locations and downhole data
are questionable. Western Nuclear drilled Section 16 using Clyde Jones Drilling
Company. Logging was performed by Geoscience Associates, Inc. (Geoscience), an
independent contract logging operator, based in Denver, Colorado. Geoscience
recorded calibration, instrument number, and k-factor on their logs and header
sheets attached to each lot. Calibration runs were recorded on all available
reduced-size logs. A complete file of drill summary sheets containing
interpreted grade, thickness, zone and alteration (oxidation) for each
mineralized interval is available. Drill hole drift surveys are also recorded;
however, original surveys are not available. A geologist examined the drill
cuttings in the field and recorded lithology and alteration on a drill log form.
Holes were drilled through the Westwater Canyon Member and into the underlying
Recapture Member. Upon completion of drilling, the hole was logged with a
gamma-ray, spontaneous-potential, and resistivity probe by either a contract
logging company or by Kerr-McGee. After running the log, a drift tool
(film-shot) was lowered into the drill hole for survey at 50-ft to 100-ft
intervals. In Section 9, the first drill hole was completed in July 1966.
Discovery was made in drill hole number 7, completed on August 2, 1970, which
encountered potentially economic mineralization at a depth of 1,900 ft. A total
of 184 drill holes were completed by September 1977. Subsequently, three drill
holes were completed from 1979 to 1982, with a total of 388,849 ft completed in
187 holes. In Section 10, the first drill hole was completed in October 1967.
Uranium was discovered in drill hole number 6, completed March 19, 1974,
mineralization at a depth of 2,318 ft. A total of 170 drill holes were completed
by October 1977. Subsequently, five drill holes were completed between 1979 and
1985, with a total of 450,838 ft completed in 175 holes. In Section 16, the
first drill holes were completed in the late 1950s and intersected uranium mineralization in drill hole number 3. In
August 1968, Western Nuclear completed the first of a series of drill holes,
encountering uranium mineralization in the second hole drilled. Western Nuclear
drilled 63 holes totaling 121,164 ft. through 1970, not including six abandoned
holes totaling 7,835 ft that did not reach the target bed.

RHR drilled four pilot holes, on Section 16, of which three
were completed as monitor wells totaling 8,050 ft for environmental baseline and
monitoring purposes in Section 16 from June through November 2007. One drill
hole was located outside of known mineralization and three holes were located
within mineralized areas. Drill sites were also chosen based on proximity to
existing roads in order to limit disturbance. Drilling was conducted by Stewart
Brothers Drilling, based in Grants, New Mexico. The entire thickness of the
Westwater Sandstone, except for zones with no recovery, was cored in the pilot
holes for these wells. The cores are PQ diameter (3 9/32 in.) and were taken
principally for laboratory testing of hydraulic conductivity, effective
porosity, density, and chemical analysis. The four pilot holes were probed by
Jet West Geophysical Services, LLC (Jet West), Farmington, New Mexico, for
gamma, resistivity, deviation, standard potential, and temperature. RHR has
developed and implemented stringent standard operating procedures for lithologic
logging of cuttings and core, and core handling (Strathmore 2008). In November
2011, a core hole was drilled at the Section 16 shaft location. The hole was
drilled to a depth of 2,053 ft. Core retrieved from this hole is currently being
used in geotechnical studies. The RHR logging procedure provides a uniform set
of instructions on how to describe cuttings and core samples, establish accurate
and consistent geologic descriptions, and ensure that proper steps, quality
controls, and required documentation are performed. A systematic methodology for
the description of lithology will ensure consistency in descriptions between
individual loggers. The RHR Lead Geologist is responsible for implementing this
procedure. Drill hole cuttings are collected at regular intervals (typically
five feet) during the drilling of a boring or well. Cuttings are collected by
the driller or designate. A portion of the cuttings are set aside for logging in
piles laid out from left to right, in groups of four piles, containing cuttings
over a total of 20 ft. Each group of four piles is separated by a space then
followed by another group of four piles. After a total of 20 piles have been
completed, a new row of cuttings is started. The Field Geologist logs the
cuttings after they have been collected and enters the data on standard logging
forms. The description of cuttings and core includes stratigraphic assignment,
lithologic type, color, matrix composition, inclusion composition, texture,
induration, alteration, presence of fractures, and other characteristics
including any unusual conditions. Rock Quality Designation (RQD) of core is
included in the standard operating procedure and measured to provide information
on the mass quality of the rock. RHR employed the services of Jet West
Geophysical Services, LLC, headquartered in Farmington, New Mexico, for all
gamma logging of its drill holes. Jet West used its own internal company
procedures to calibrate and operate the gamma-ray probe, and provided a digital
and graphic log of the readings for each drill hole. An RHR project geologist
was onsite during these activities. RHR drill hole collar locations were
surveyed in 2008 by Apogen Technologies R&D, based in Los Alamos, New
Mexico, and resurveyed in 2010 by Land Surveying Company, LLC, based in Santa
Fe, New Mexico. Both companies surveyed drill hole collars in State Plane
coordinates, NAD 83, New Mexico Western Zone 3003.

Jet West conducted downhole surveys using a deviation tool,
which utilizes an accelerometer and magnetic compass to determine tool
inclination and corrected direction from magnetic to true north. Downhole
measurements were taken at 20-ft, 25-ft, or 50-ft spacing. Easting, northing,
and elevation points were also computed for each azimuth and dip measurement.
Jet West conducted periodic checks on the deviation tool for operational
accuracy.

When completing the four monitor well pilot holes on the Roca
Honda property, RHR cored the Westwater Sandstone in each of the holes. Core
recovery measurements were taken following the core logging procedure and
recorded on the lithologic log. Core recoveries within the RHR drill holes are
as follows:

53

---

- S1: Over the interval from 1880 ft to 2,092 ft, core recovery varied
  locally from approximately 62% to 100% in the Jmw A sand exclusive of two
  intervals (1,909.4 ft to 1,916 ft and 2,005.6 ft to 2,007 ft) that had 0%
  recovery. Below the Jmw A, core recoveries in the A-B1 shale to Jmw B sand
  range from 77% to 100%.
- S2: Over the interval from 1,651 ft to 1,855 ft, core recoveries within
  the Jmw A sand varied from 55% to 97%, with 0% recovery from 1,743 ft to 1,756
  ft, 1,774 ft to 1,778-ft, 1,809.9 ft to 1,814 ft, 1,818.5 ft to 1,834 ft,
  1,835.1 ft to 1,836.5 ft, and 1,848 ft to 1,855 ft. Below the Jmw A sand, 0%
  to 50% recovery was recorded down to the B1-B2 shale.
- S3: Recoveries of 91% to 93% were recorded in the Jmw A sand and 98% to
  100% below in the A-B1 shale and Jmw B2 sand. Recovery was not recorded below
  Jmw B2. No recovery of core from 1,840 ft to 1,942 ft.
- S4: Over the interval from 1,775 ft to 2,004.9 ft, no recovery from
  1,812.0 ft to 1,825.0 ft, 1,860.0 ft to 1,861.0 ft, 1,886.3 ft to 1,902.5 ft,
  1,921.7 ft to 1,922.5 ft, and 1,961.0 ft to 1,975.0 ft. Recoveries of 50% to
  100% were recorded in the A-B1 shale to Jmw D sand. Jmw A sand was not
  recorded on the lithologic log.

Pilot hole S-1 was cored and chemically assayed, but due to
hole stability issues a gamma-log was not run. S-1a was drilled approximately
30-ft from S-1. Core was not retrieved, but a gamma-log of the mineralized zone
was run. The purpose of drilling S-1 and S-1a was to retrieve core and install a
monitoring well. Issues encountered during the drilling of S-1 led to the
decision to drill, log and install a well without coring S-1a. Pilot holes S-2,
S-3, and S-4 were cored. Chemical assays were conducted for all mineralized zone
core.

Mineralization

The uranium found in the Roca Honda mine project area is
contained within five sandstone units of the Westwater Canyon Member. Zones of
mineralization vary from approximately one foot to 32 ft thick, 100 ft to 600 ft
wide, and 200 ft to 2,000 ft long. Uranium mineralization in the project area
trends west-northwest, consistent with trends of the fluvial sedimentary
structures of the Westwater Canyon Member, and the general trend of
mineralization across the Ambrosia Lake subdistrict. Core recovery from the 2007
drilling program indicates that uranium occurs in sandstones with large amounts
of organic/high carbon material. Non-mineralized host rock is much lighter
(light brown to light grey,) and it has background to slightly elevated
radiometric readings. Uranium mineralization consists of unidentifiable
organic-uranium oxide complexes. The uranium in the project area is dark grey to
black in color and is found between depths of approximately 1,650 ft to 2,600 ft
below the surface. Although coffinite and uraninite have been identified in the
Grants Mineral Belt, their abundance is not sufficient to account for the total
uranium content in a mineralized sample. Admixed and associated with the uranium
are enriched amounts of vanadium, molybdenum, copper, selenium, and arsenic in
order of decreasing abundance. Primary mineralization pre-dates, and is not
related to, present structural features. There is a possibility of some
redistribution and stack ore along faults; however, it appears that most of the
Roca Honda mineralization is primary. Redistributed, postfault, or stack
mineralization occurs in the Ambrosia Lake subdistrict of the Grants Mineral
Belt, but is not apparent in the Roca Honda area.

Paleochannels that contain quartz-rich, arkosic, fluvial
sandstones are the primary mineralization control associated with this trend.
Previous mining operations within the immediate area suggest that faults in the
Roca Honda area associated with the San Mateo fault zone post-date the
emplacement of uranium, therefore, it can be expected that mineralized zones in
the Roca Honda area are offset by faults. The mineralization is typically
confined to sandstones in the Westwater Canyon Member, although there is some
overlap into the shales that divide the sandstones, and also some minor
extension (less than 10 ft) into the underlying Recapture Member. The
mineralization is contained in the Westwater Canyon Member sandstones across the project area, but in Sections 9
and 16, the mineralization is typically found in the upper sandstones (A, B1,
and B2). In Section 10, the A and B1 sandstones pinch out in some areas due to
thickening of the overlying Brushy Basin Member. Mineralization in the middle
and western portions of Section 10, and it is typically in the lower sandstones
(sands C and D). Sedimentary features may exhibit control on a small scale. At
the nearby Johnny M mine, a sandstone scour feature truncates underlying black
mineralization, indicating nearly syngenetic deposition of uranium
mineralization with the sandstone beds. Uranium mineralization in places is
related to clay-gall (cobbles) layers within the host sandstone.

54

---

The presence of pyrite and bleaching alteration is also
important. Alteration bleaching forms a halo that encloses mineralization. The
bleaching caused by the removal of reddish ferric-iron pigmentation imparts a
light grey color to the sandstone, and a greenish rim on red-colored claystone
cobbles or galls.

Sampling and Analysis

All mineralized intercepts used for historical resource
estimates were calculated by Kerr-McGee from gamma-ray logs probed for each
drill hole. Each log consists of gamma-ray, resistivity, and
spontaneous-potential curves plotted by depth. The equivalent U3O8 (eU3O8)
content was calculated by Kerr-McGee following the industry-standard method
developed originally by the U.S. Atomic Energy Commission (the AEC), a
precursor to todays U.S. Nuclear Regulatory Commission (the NRC).

Uranium grade is determined radiometrically by measuring the
radioactivity levels of certain daughter products formed during radioactive
decay of uranium atoms. Most of the gamma radiation emitted by the nuclides in
the uranium decay series is not from uranium, but from daughters in the series.
Where daughter products are in equilibrium with the parent uranium atoms, the
gamma-ray logging method will provide an accurate measure of the amount of
parent uranium that is present. A state of disequilibrium may exist where
uranium has been remobilized and daughter products remain after the uranium has
been depleted, or where uranium occurs and no daughter products are present.
Where disequilibrium exists, the amount of parent uranium present can be either
underestimated or overestimated. Therefore, it is important to obtain
representative samples of the uranium mineralization to confirm the radiometric
estimate by chemical methods. Based on Kerr-McGees extensive operating
experience in the Ambrosia Lake sub-district, there were no historical concerns
regarding disequilibrium for gamma ray results. Additionally, RHR cores showed
no major negative disequilibrium.

RHR completed four pilot holes in 2007 and one geotechnical
hole in 2011. RHR has developed stringent in-house standard operating procedures
for core handling and decontamination of small equipment used for sampling.
Detailed results of the RHR drilling are contained in the NI 43-101 report for
Roca Honda.

The standard operating procedures provide guidance for proper
and consistent core collection practices, and to ensure that proper core
handling procedures, quality control, and required documentation are undertaken.
The RHR Lead Geologist was responsible for implementing the core handling and
sampling procedures. The RHR Field Geologist was responsible for ensuring that
all standard operating procedures were conducted in accordance with Strathmore
standards, under the direction of the RHR Lead Geologist. The Field Geologist
observed the core from the time it was pulled from the hole until it was
transported to a locked storage facility adjoining RHRs Grants geology office.
Core intervals selected for sampling were split in half lengthwise with a
hydraulic splitter. One half was sent for analysis, with the other half logged
and archived with the remaining core. Core samples were inserted into sample
bags labelled with the well identification, core run number, date, and core
interval. Core intervals sampled for laboratory analysis were sealed to preserve
the natural state of the core. A sample block is placed in the location of the
sampled core and labelled with the boring or well identification, date, depth
intervals, sample identification, sample type, and the name of the individual or
organization receiving the sample. Each core box is photographed using a digital
camera and includes a color bar, scale and label containing the borehole
designation, box number, box interval, and the date of the photograph. All
photography logs and photographs are archived by RHR. Core Box and Custody
Record Forms are completed before the core box is closed and sealed. All records
and forms are reviewed by the Field Geologist for accuracy and completeness.

Pilot hole S-1 was cored and assayed, but it was not possible
to run a gamma-log. Pilot hole S-1a was drilled approximately 30 ft from S-1,
but was not cored. Pilot holes S-2, S-3, and S-4 were cored. The gamma-ray probe
intercepted zones of moderate to significant uranium mineralization in S-1a,
S-2, and S-3.

RHR has completed four pilot holes for monitor wells and cored
the Westwater Sandstone in each of the holes. The cored intervals are listed in
Section 10 Drilling under Recovery. RHR also completed a geotechnical hole in
2011 that is not included in the resource data base. Selected intervals of core
were split and sampled for multi-element chemical analysis (uranium, vanadium,
organic carbon) by inductively coupled plasma mass spectrometry (ICP-MS) and
atomic emission spectrometry (ICP-AES) or for hydrologic studies. Chemical
analyses were performed by Energy Laboratories, Inc. (ELI), Casper, Wyoming, by
ICP-MS and ICP-AES methods, and by The Mineral Lab, Inc., Lakewood, Colorado,
using X-ray fluorescence methods (XRF). Uranium is reported as U (ppm), and
converted to % U3O8 (ppm U* 1.17924/10,000) . Additional sampling continued in
2008. Samples were taken adjacent to the 2007 core samples. Closed can analyses
were also conducted on samples for comparison with ICP and XRF results. The
closed can method involves calculating the radiometric assay of the sample by
determining the amount of gamma radiation given off by the daughter products of
natural uranium radioactive decay. The difference between the radiometric
assay and the chemical assay determined using ICP and XRF is what is referred
to as disequilibrium. The core sample results are summarized on Pages 11.8 to
11.11 in the Roca Honda Technical report.

It is important to establish an understanding of the expected
state of equilibrium of uranium in the Roca Honda deposit. As previously
discussed in this section, chemical equilibrium of uranium versus radiometric
values is nearly in balance or slightly positive for mineralization in the
Westwater Canyon Member in the southeastern part of the Ambrosia Lake
subdistrict of the Grants Mining District. RHR has results of analyses of
chemical equilibrium from four samples from three core holes (totaling 17-ft of
mineralized core) located in Section 16. Results indicate positive average
equilibrium (chemU3O8/ eU3O8)for the four samples. Based on a review
of available reports describing the state of chemical equilibrium for uranium in
the vicinity of the Roca Honda deposit and in similar deposits with primary type
uranium mineralization, RPA considered it probable that the Roca Honda deposit
taken as a whole, will have an average state of equilibrium that is slightly
favorable with regard to chemical uranium versus eU3O8. RPAis of the
opinion that there is a low risk of negative equilibrium (chemical uranium lower
than radiometrically determined uranium) in the Roca Honda deposit. Additional
sampling and analyses are recommended to supplement results of the limited
disequilibrium testing conducted by RHR.

Security of Samples

RHR implemented and followed strict standard operating
procedures as documents in Standard Operation Procedure 006 Sampling handling,
packaging, shipping, and chain of custody (2008). The Standard Operating
Procedure outlines the preparation of environmental and waste characterization
samples for shipment to the offsite analytical laboratory, and the chain of
custody procedures to follow from the sample collection stage to the entry of
results into the RHR database.

Mineral Reserve and Resource Estimates

RPA prepared an updated NI 43-101 compliant Mineral Resource
estimate for the Roca Honda deposit in the Roca Honda Technical Report. The
following table summarizes the total Mineral Resources for the Roca Honda
Project. The Mineral Resource estimate and classification are in accordance with
the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards
on Mineral Resources and Mineral Reserves (CIM definitions) incorporated in NI
43-101.

There are currently no Mineral Reserves for the Roca Honda
project.

RHR generated lithology wireframe models for the hangingwall
and footwall of the Jmw A, Jmw B1, Jmw B2, Jmw C, and Jmw D sand units across
the Roca Honda property. Integrated stratigraphic grid models based on modelling
algorithms were generated in Vulcan® for lithology surface wireframes using the
drill hole intervals corresponding to the respective sand unit horizons. RPA
reviewed the lithology surfaces and noted that the modelling algorithms do not
always adhere to the sand unit intervals in the drill holes. Small local
variances exist, and are most noticeable where mineralization is located
adjacent to, but outside of a sand unit wireframe model, yet the drill hole log
indicates that the mineralization is located inside the sand unit. Although
there are no overall significant discrepancies between the models and the logged
lithology intervals, RPA recommends revising the lithology surfaces in the
future, once additional drill data have been collected. The Roca Honda property
was subdivided into two modelling zones based on sand unit and mineralization
extents. The Northeast zone includes mineralization in the C and D sands in
Section 10. The Southwest zone includes mineralization in the A and B sand units
crossing the Section 9, 10, and 16 boundaries. Block model and modelling
boundaries are illustrated in Figure 14-1. All mineralization surfaces were
generated by RPA in ARANZ Geo Limiteds Leapfrog® version 2.1.1.209. Mineralized
drill hole intervals were selected by sand unit, with a minimum thickness of six
feet and a minimum grade of 0.1% U3O8. Additional intervals below the minimum
thickness and grade were selected in holes adjacent to the mineralized holes, to
restrict the extent of the wireframe models. Surfaces were generated for the
hanging wall and footwall of mineralized zones within each sand unit. These
surfaces were used to create solids for each mineralized zone. A 0.1% U3O8 grade
contour was created around mineralized intervals with a minimum thickness of six
feet in plan view. Solids were generated from the grade contours and used as
boundaries to cookie cut individual mineralization solids.

Roca Honda mineralization wireframes contain a total of 197
mineralization intercepts from 105 drill holes. Grade statistics are shown in
the Roca Honda Technical Report.

All mineralization intercepts located inside the mineralization
wireframes were used together to determine an appropriate capping level for all
mineralized zones. Mineralization intercept data were analyzed using a
combination of histogram, probability, percentile, and cutting curve plots. All
mineralization intercepts flagged inside the mineralization wireframes are plotted in
Figure 14-7. Although drill hole 10124 contains a high grade of 2.35% U3O8,
located in the C sand, it is located adjacent to and along the same horizon as
other high grade mineralization intercepts. RPA is of the opinion that high
grade capping is not required at this time, however, capping should be reviewed
once additional data have been collected.

Run-length composites were generated at six foot lengths inside
the domain wireframes and flagged by mineralization domain. The Southwest zone
composite database includes a small percentage of composites less than 1.5 ft.
These accounted for a small percentage of the total composites and will not
significantly affect the resource estimate. RPA recommends reviewing and
removing all small length composites in future resource composite databases.

Two composite databases were generated for resource estimation,
rhr_sw_6ft.cmp.isis for the A and B zones and rhr_ne_6ft_.cmp.isis for the C and
D zones. Detailed statistics for the final composite database are presented in
the Roca Honda Technical report.

Two Roca Honda non-rotated block models were generated in
Vulcan®. The NE_Ore_Body.bmf includes mineralization in the C and D sand units.
The SW_Ore_Body.bmf includes mineralization in the A, B1, and B2 sand units.
Parent blocks are 50-ft (x) by 50-ft (y) by 30-ft (z) in size. Blocks inside
mineralization wireframes were limited to a maximum of 10-ft (x) by 10-ft (y) by
6-ft (z) with one foot by one foot by one foot sub-blocks generated along
mineralization domain wireframe boundaries. Block model extents are listed in
the Roca Honda Technical Report.

No records of sampling for bulk density determinations were
found from work performed prior to RHRs recent core drilling project. Fitch
assumed a tonnage factor of 15 ft3/st for the June 30, 2010 resource estimate
(Fitch 2010). This is the typical tonnage factor used by most operators
including Kerr-McGee in the Ambrosia Lake subdistrict and the Mt. Taylor
deposit, for mineralized intervals in the Westwater sandstone unit. This tonnage
factor was derived by the AEC and the major operators from years of actual
mining and milling based on over 300 million pounds of U3O8 that was produced in
the Ambrosia Lake subdistrict. The recently completed density determinations by
RHR of 11 core samples from the four pilot holes S1, S2, S3, and S4 yield an
average tonnage factor of 15.9 ft3/st for mostly barren sandstone of the
Westwater Canyon Member. One sample, RH07-0009 is from a mineralized interval
and has a tonnage factor less than (i.e. density greater than) 15 ft3/st. Fitch
(2008) recommended carrying out density determination of the remaining core
samples containing uranium mineralization to better characterize the specific
gravity for subsequent resource estimations. RPA concurs with this
recommendation, but suggests additional density determinations should be carried
out using mineralized material, to confirm and support future resource
estimates.

Block grades were estimated using the Inverse Distance Cubed
(ID3) method. Domain models were used as hard boundaries to limit the extent of
influence of composite grades within the domains. Suitable variograms could not
be generated for individual or combined domain models due to the small number of
contained sample composites. Search ranges were determined visually based on
continuity of mineralization and drill hole spacing. Search directions were
determined visually for each domain. Isotropic search ranges in the major and
semi-major directions following the trend of individual domain models were
applied. Minor search ranges were also determined visually and were shorter.
Search directions and trends are listed the Roca Honda Technical Report. Two
grade estimation passes were run with the major, semi-major, and minor search
ranges increased by a factor of 1.5 in the second estimation run. Estimation
flags were stored for each estimation run based on increasing search distances.
The number of samples and holes were stored in separate block variables for use
in determining resource classification. Octant restrictions were not enforced in
order to preserve local grades. Only the closest composites to block centroids
(adhering to defined trends) were used. Grade estimation parameters are listed
in the Roca Honda Technical Report.

Visual validation comparing mineralization intercepts and
composite grades to block grade estimates showed reasonable correlation with no
significant overestimation or overextended influence of high grades apparent. A
vertical longitudinal section through the C4 model is presented in the Roca
Honda Technical Report. Final block grades were compared to nearest neighbor
block grades by domain. Nearest neighbor grade estimates were run with
run-length composites generated across the thickness of the mineralization
models. The comparison showed good correlation with less than 10% difference in
average grade for most domains. A few domains showed larger grade differences.
B2_6 had higher average nearest neighbor grades due to widely spaced high grade
composites influencing a higher number of blocks. B1_9 contained only one hole,
with a higher run-length composite grade compared to lower grade six-foot
composites. No significant discrepancies were identified with the block grade
validation.

Roca Honda resource classification within mineralization
domains is primarily based on drill hole spacing and continuity of grade, and
was manually completed after review of the geology and mineralization. Blocks
estimated by drill holes with a maximum spacing of approximately 100-ft, and
well established geological and grade continuity, were classified as Measured
Resources. Blocks estimated by drill holes with a maximum spacing of
approximately 200-ft, and sufficient geological and grade continuity, were
classified as Indicated Resources. Manual adjustments were made to eliminate the
unusual artifacts generated from the estimation passes. Inferred Resources have
been defined by the wide spacing of drill holes and resultant uncertainty in
geological and grade continuity.

Mining Operations

To arrive at the Mineral Resources that are potentially
mineable at the Roca Honda project, RPA used a diluted cut-off grade of 0.110%
eU3O8, a minimum mining thickness of six (6) feet, the historical mining
recovery of 85% for the step room-and-pillar mining method and 90% recovery for
the drift-and-fill mining method. Measured and Indicated Mineral Resources that
are potentially mineable are estimated to be 2.033 million tons at a diluted
grade of 0.365% U3O8. Inferred Resources that are included in the PEA are
estimated to be 1.400 million tons at a diluted grade of 0.355% U3O8. Mineral
Resources that are potentially mineable are based on an underground mine design
and stope schedule. The mineralization is relatively flat-lying, and will be
mined with a combination of step room-and-pillar and drift-and-fill stoping.

In the Roca Honda Technical Report, RPA indicated that the
mining plan is relatively simple, and the mining conditions are expected to be
fair after the ground is sufficiently dewatered.

Feasibility and Resource Studies

The economic analysis contained in the Roca Honda Technical
Report is based, in part, on Inferred Mineral Resources, and is preliminary in
nature. Inferred Resources are considered too geologically speculative to have
mining and economic considerations applied to them and to be categorized as
Mineral Reserves. There is no certainty that the reserves development,
production, and economic forecasts on which this PEA is based will be
realized.

A pre-tax cash flow projection has been generated from the LoM
schedule and capital and operating cost estimates. A summary of the key criteria
is provided below.

- There is a New Mexico mining royalty payable on the value of mineral
  production for New Mexico state leases. The royalty is based upon the
  operating cash flow less a development allowance, depreciation and a
  processing allowance.
- New Mexico mining and private royalties on value of minerals extracted as
  shown below:

- Landowner Access (1%);
- Section 9 Gross Royalty (1%); and
- Section 16 New Mexico State Lease Royalty (5%).

Cash Flow Analysis

Considering the Project on a stand-alone basis, the base case
undiscounted pre-tax cash flow without toll milling and including contingency
totals $713 million over the mine life, and payback occurs early in the fifth
year of production. The annual uranium production during operation is 2.6
million pounds per year and a maximum annual production of 3.9 million
pounds.

The pre-tax IRR is 19.2% and the pre-tax net present value
(NPV) is as follows:

- $713.1 million at a 0% discount rate;
- $350.8 million at a 5% discount rate;
- $220.1 million at an 8% discount rate; and
- $106.0 million at a 12% discount rate.

The net revenue per pound of product is expected to be $73.55,
and the operating cost per pound of product is expected to be $23.82.

Permitting

The Roca Honda project is at an advanced stage of permitting.
The Draft Environmental Impact Statement (DEIS) was completed by the
USFS in April 2013, and the company expects the Final Environmental Impact
Statement (FEIS) to be published in early 2015. Other major permits
required for Roca Honda include a Permit to Mine issued by the New Mexico Mining
and Minerals Division, a Discharge Permit issued by the New Mexico Environmental
Department, and a Mine Dewatering Permit issued by the New Mexico State
Engineers Office. The Mine Dewatering Permit was approved in December 2013. The two other major permits are in the agency
review stage with a draft Discharge Permit expected in the first half of 2014,
and the Permit to Mine expected after approval of the FEIS in mid- to late-2015.
Permit approvals from the U.S. Army Corps of Engineers and the U.S.
Environmental Protection Agency are also required for discharge of treated mine
water associated with mine development and operation. Applications for these two
permits are also presently undergoing agency review.

Processing

In November 2006, Strathmore purchased 620 acres of land in the
Ambrosia Lake area known as Peña Ranch for a potential conventional mill
development. The planning process for the construction of a mill in New Mexico
to support the Roca Honda resource began in 2007. Initial site studies for the
mill and tailings, as well as mill process design studies were completed.

With Energy Fuels acquisition of Strathmore in August 2013,
studies are underway to evaluate trucking all or a portion of the Roca Honda
Projects resources to the White Mesa Mill, thereby avoiding the time and cost
of constructing a new mill in New Mexico.

Energy Fuels has a 100% interest in a number of breccia pipe
uranium deposits in the Arizona Strip District of northwestern Arizona,
including: Arizona 1, Canyon, Pinenut, EZ 1, EZ 2, WHAT, DB 1, Kanab North,
John, Lisa, Otto, Why and Not. These breccia pipe deposits, in addition to
another deposit in Arizona called Moonshine Springs, were acquired by Denison
from Pathfinder Mines Corp. (Pathfinder) in 2007. Moonshine Springs is
a sandstone hosted deposit near the surface, gradually becoming deeper toward
the north. All of these properties were subsequently acquired by Energy Fuels in
its June 2012 acquisition of Denisons US Mining Division.

The Arizona Strip is an area largely bounded on the north by
the Arizona/Utah state line; on the east by the Colorado River and Marble
Canyon; on the west by the Grand Wash Cliffs; and on the south by a midpoint
between the city of Flagstaff and the Grand Canyon. The area encompasses
approximately 13,000 square miles.

Since 1980, when mine development first began at the Hack
Canyon II mine, the Arizona Strip has produced in excess of 19 million pounds of
uranium from seven mines. Of these mines, Hack Canyon I, II, and III, Pigeon and
Hermit are depleted and have been reclaimed. In addition, the Kanab North mine
is depleted and in reclamation. The Arizona 1 mine was placed on standby by the
Company in February 2014 due to the depletion of the economic resource.

62

---

Ore from the Arizona Strip mines is hauled by truck from the
mine sites to the Companys White Mesa Mill. The Arizona 1 and Pinenut Mines are
approximately 307 road miles, and the Canyon Project is 325 road miles from the
Mill.

The Arizona Strip mines are held by Energy Fuels on unpatented
claims located on land managed by the BLM and U.S. Forest Service
(USFS), except for the Moonshine Springs deposit, which is held by a
combination of mineral claims and a mineral lease. There is a 3.5% yellowcake
royalty on the Canyon property.

Mining operations began at Arizona 1 in late 2009 and continued
until February 2014 at which time the project was placed on standby. At Pinenut,
mine development activities began in late 2010. Ore production commenced in the
summer of 2013 and is expected to continue until mid-2014 at which time ore
production is expected to be placed on standby. At Canyon, all surface
facilities for shaft sinking are in place, and (subsequent to the filing of the
Technical report) shaft sinking commenced in February 2013, at a depth of 50
feet below the surface. Development progressed to a depth of 280 feet during
2013. In November 2013, shaft sinking at Canyon was placed on standby.
Reclamation has begun at the Kanab North mine and all that remains is to remove
surface waste rock, grade the surface and re-vegetate. The EZ Complex is
currently in the permitting process. The What, DB-1, Why, John, Not, Lisa, Otto
and Moonshine Springs properties have no development on site or plans for
permitting at this time.

Property Description and Location

Prior to its bankruptcy in 1995, EFN located and developed to
various stages, numerous uranium mineralized breccia pipe structures in
northwestern Arizona, between Utah and the Grand Canyon, an area termed the
Arizona Strip. Most of Energy Fuels breccia pipes are between the town of
Fredonia, on the Arizona-Utah state line, and Grand Canyon National Park. One
deposit, Canyon, is located south of the national park.

Arizona 1 is located in Mojave County, Arizona, about 45 miles
southwest from Fredonia, Arizona by unsurfaced road. Energy Fuels property
position consists of 10 unpatented mining claims covering approximately 207
acres, located on land managed by the U.S. Bureau of Land Management
(BLM).

Pinenut consists of 10 unpatented mining claims encompassing
207 acres, located on land managed by the BLM. It is located 45 miles south of
Fredonia in Mojave County, Arizona and is accessible via an unsurfaced road.

The Canyon project is in north central Arizona, 153 miles north
of Phoenix and six miles south of Tusayan, Arizona in the Kaibab National
Forest, Coconino County and is accessible by an unsurfaced road. The Canyon site
consists of nine unpatented mining claims encompassing approximately 186 acres,
located on land managed by the U.S. Forest Service (USFS). There is a
3.5% yellowcake royalty on the Canyon property.

The EZ Complex is also located in Mohave County, Arizona, about
30 miles southwest of Fredonia, Arizona. The EZ Complex is comprised of 12
unpatented mining claims covering approximately 248 acres, located on land
managed by the BLM. There is a 1.0% yellowcake royalty on the EZ Complex
properties.

Holding costs for the Arizona 1, Pinenut, Canyon and EZ
properties are minimal and consist entirely of annual fees for unpatented mining
claims ($140 per claim per year) and county filing fees ($10 per claim per
year). Unpatented mining claims expire annually, but are subject to indefinite
annual renewal by filing appropriate documents and paying the fees described
above. In addition, holders of unpatented mining claims are generally granted
surface access to conduct mineral exploration and mining activities.

There are no outstanding environmental liabilities to which the
project is subject.

Arizona 1 is a fully developed mine, with the production shaft
having been completed for about 1,250 ft. of its proposed final 1,650 ft. depth.
In February 2014, the Arizona 1 was placed in standby due to the depletion of
the economic resource. Drill stations were cut near the current shaft bottom and
some 40,000 ft. of drilling, including 34,000 ft. of percussion and 6,000 ft. of
core drilling, were completed from that point. The mine is located in Sections
22 and 23, T36N, R5W, Mojave County, Arizona, about 45 mi. southwest of Fredonia
by unsurfaced road. A headframe, hoist, compressor, and fully-sunk shaft are in
place. Haulage distance from Arizona 1 to the White Mesa mill at Blanding, Utah,
is 307 mi.

The Canyon Project is a partially developed mine with: a
headframe, a hoist, a compressor and a partially sunk shaft. The site is located
in Sections 19 and 20, T29N, R3E, Coconino County, Arizona. The haulage distance
from Canyon to the White Mesa mill at Blanding, Utah, is 325 mi.

Pinenut is a fully developed underground mine which produced
25,807 tons of ore at an average grade of 1.02% U3O8 containing 526,350 pounds
U3O8 in 1989. The Pinenut Mine was placed into production by Energy Fuels in the
summer of 2013. A hoist, headframe, fully developed shaft and compressor are in
place. Pinenut is located in an unsurveyed portion of T36N, R4W, Mojave County,
Arizona, about 45 mi. south of Fredonia by unsurfaced road. The haulage distance
from Pinenut to the White Mesa mill at Blanding, Utah, is 317 mi.

There is no infrastructure currently on the EZ property. The
proposed disturbance for the EZ property will be between 20 acres and 40 acres.
A series of permits and approvals will be required from the BLM, ADEQ, Mohave
County and other agencies.

Please see Mineralizationsection below for the
location of all known mineralized zones and mineral resources. Please see
Permittingsection below for the current status of permitting and
approvals for the project.

Accessibility, Local Resources, Physiography and
Infrastructure

Climate in northern Arizona is semi-arid, with cold winters and
hot summers. January temperatures range from about 7° F to 57° F and July
temperatures range from 52° F to 97° F. Annual precipitation, mostly in the form
of rain but some snow, is about 12 inches. Vegetation on the plateaus is
primarily open piñon juniper woodland and shrubs. Mining operations can be
conducted on a year around basis.

The region north of the Grand Canyon is very sparsely
populated. Due to the inaccessibility and low population, infrastructure is not
well developed. The nearest commercial centers to the Kanab and Fredonia area
are the towns of St. George and Cedar City, Utah, both approximately 88 miles to
the northwest by road. The White Mesa Mill is approximately 275 miles by road
from Fredonia and about 325 miles by road from the Canyon Project.

History

Uranium exploration and mining of breccia pipe uranium deposits
started in 1951 when a geologist employed by the U.S. Geological Survey noted
uranium ore on the dump of an old copper prospect on the South Rim of the Grand
Canyon of Northern Arizona. The prospect was inside the Grand Canyon National
Park, but on fee land that predated the park. A mining firm acquired the
prospect and then mined a significant high grade uranium deposit, called the
Orphan Mine. By the time mining ended in the early 1960s, 4.26 million pounds of
U3O8 and some minor amounts of copper and silver had been produced.

64

---

After the discovery of the first deposit in the 1950s, an
extensive search for other deposits was made by the government and industry, but
only a few low grade prospects were found. Exploration started again in the
early 1970s. In the mid-1970s, Western Nuclear Inc. (Western Nuclear)
acquired the Hack Canyon prospect located about 25 miles north of the Grand
Canyon and found high grade uranium mineralization offsetting an old shallow
copper/uranium site. In the next few years, a second deposit was found
approximately one mile away.

EFN acquired the Hack Canyon property from Western Nuclear in
December 1980. Development started promptly, and the Hack Canyon mine was in
production by the end of 1981.

The Kanab North deposit was discovered in 1981, but development
did not begin until late 1984. Kanab North was fully developed in 1988 and
operated until December 1990 when it was placed on standby.

Production totalled about 2.8 million pounds of U3O8 at an
average grade of just over 0.50% U3O8. The site was placed in reclamation by the
Company in late 2013.

EFN explored the Arizona 1 deposit with a total of 253 drill
holes, including: 18 core holes from underground drill stations with a total
footage of 6,122 feet; 17 rotary holes from surface with a total footage of
25,289 feet; and 218 long holes from underground drill stations with a total
footage of 36,189 feet. Mine development of the Arizona 1 ore body began in 1990
but was suspended in 1992, with the shaft at a depth of 1,254 feet.

The Canyon deposit is located on mining claims that EFN
acquired in 1982. Drilling completed by EFN in 1983 identified a significant
deposit. EFN drilled an additional 36 holes from May 1983 through April 1985 to
delineate the uranium mineralization and to determine placement of the mine
shaft and water supply well. Additional drilling of six holes was completed in
1994. Development of the site was discontinued as a result of low uranium
prices.

The Pinenut Mine was developed in 1989 after 29 holes were
drilled from the surface. A shaft was then sunk to 1380 feet and five
development drifts were excavated. Four hundred and eighty three long holes were
drilled to define the ore body and mining of a large, high grade ore zone was
commenced on the lowest level. In 1991, due to dropping uranium prices, the mine
was put on standby.

The EZ Complex was drilled in the 1980s by Pathfinder.
Pathfinder drilled 81 holes for a total of 139,118 feet. Pathfinder entered into
a joint venture with EFN and prepared mineral resource estimates for the two
deposits in 1988. At the time of International Uranium Corporations
(IUC) acquisition of EFNs mining properties in 1997, the
EFN/Pathfinder joint venture was terminated and control of the EZ 1 and EZ 2
projects reverted back to Pathfinder. Denison acquired the EZ 1 and EZ 2
projects from Pathfinder in 2007.

EFN identified and investigated more than 4,000 circular
features in northern Arizona. About 110 of the most prospective features were
explored by deep drilling, and approximately 50% of those drilled were shown to
contain uranium mineralization. Ultimately, nine deposits were deemed worthy of
development. Total mine production from the EFN breccia pipes from 1980 through
1991 was approximately 19.1 million pounds U3O8 at an average grade of just over
0.60% U3O8.

Most of the EFN assets were acquired by Denisons predecessor
IUC in 1997 and by the Company in June 2012 upon acquisition of the US Mining
Division. Since that time, Denison and then Energy Fuels has maintained ownership of the Kanab North, Pinenut, Arizona
1, and Canyon deposits. All other EFN breccia pipe prospects were dropped by
Denison. In addition to the EFN breccia pipe deposits, Denison acquired several
additional breccia pipe deposits (EZ 1, EZ 2, WHAT, WHY, NOT, John, Lisa, Otto
and DB 1) and one sandstone type deposit (Moonshine Springs) from Pathfinder,
all of which were acquired by Energy Fuels as part of the US Mining
Division.

Geological Setting

Parts of two distinct physiographic provinces are found within
Arizona: the Basin and Range province in the southern and western edge of the
state, and the Colorado Plateau province in most of northern and central
Arizona. The Arizona Strip lies within the Colorado Plateau province.

Surface exposures within the Arizona Strip reveal sedimentary
and volcanic rocks ranging in age from upper Paleozoic to Quaternary; the area
is largely underlain by Mississippian through Triassic sedimentary rocks.
However, exposed within the Grand Canyon are older rocks reaching Precambrian in
age.

Arizona 1, in common with all other breccia pipes within the
Arizona Strip, was believed by EFN to have had its origin as a solution collapse
of the Redwall Limestone. This collapse worked its way upward through the
overlying formations where the throat diameter is on the order of 200 feet to
300 feet. Vertical displacement in the throat averages about 175 feet. Uranium
mineralization is distributed irregularly over a depth interval of approximately
650 feet mainly at the level of the Hermit Shale formation to a maximum depth of
about 1,400 feet from surface.

At the Canyon deposit, the surface expression of the pipe is a
broad shallow depression in the Permian Kaibab Formation. The pipe is
essentially vertical with an average diameter of less than 200 feet, but it is
considerably narrower through the Coconino and Hermit horizons (80 feet). The
cross sectional area is probably between 20,000 and 25,000 square feet. The
deposit extends for at least 2,300 feet from the Toroweap limestone to the upper
Redwall horizons. The ultimate depth of the deposit is unknown at this time.

Mineralization extends vertically over about 1,700 vertical
feet, with ore grade mineralization found mainly in the Coconino, Hermit, and
Esplanade horizons and at the margins of the deposit in fracture zones. Sulphide
zones are found scattered throughout the deposit but are especially concentrated
(sulphide cap) near the Toroweap Coconino contact, where the cap averages 20
feet thick and consists of pyrite and bravoite, an iron-nickel sulphide. The ore
assemblage consists of uranium-pyrite-hematite with massive copper sulphide
mineralization common in and near the ore zone. The strongest mineralization
appears to occur in the lower Hermit-upper Esplanade horizons in an annular
fracture zone.

Uranium mineralization in the EZ 1 and EZ 2 deposits is located
primarily in the Coconino and Hermit horizons.

Deposit Types

Paleozoic sedimentary rocks of northern Arizona are host to
thousands of breccia pipes. These deposits are known to extend from the
Mississippian Redwall Limestone to the Triassic Chinle Formation, which makes
about 4,000 feet of section. However, because of erosion and other factors, no
single deposit has been observed cutting through the entire section. No deposit
is known to occur above the Chinle Formation or below the Redwall Limestone.

66

Breccia pipes within the Arizona Strip are vertical or near
vertical, circular to elliptical bodies of broken rock. Broken rock is comprised
of slabs and rotated angular blocks and fragments of surrounding and
stratigraphically higher formations. Hence, many geologists consider these
deposits to have been formed by solution collapse of underlying calcareous
rocks, such as the Redwall Limestone. Surrounding the blocks and slabs making up
the breccia is a matrix of fine material comprised of surrounding and overlying
rock from various formations. The matrix has been cemented by silicification and
calcification for the most part.

Breccia pipes are comprised of three interrelated features: a
basinal or structurally shallow depression at surface (designated by some as a
collapse cone); a breccia pipe which underlies the structural depression; and
annular fracture rings which occur outside of, but at the margin of the pipes.
Annular fracture rings are commonly, but not always, mineralized. The structural
depression may range in diameter up to 0.5 miles or more, whereas breccia pipe
diameters range up to about 600 feet; the normal range is 200 feet to 300 feet.

Mineralized breccia pipes found to date appear to occur in
clusters or trends. Spacing between breccia pipes ranges from hundreds of feet
within a cluster to several miles within a trend. Pipe location may have been
controlled by deep seated faults, but karstification of the Redwall Limestone in
Mississippian and Permian times is considered to have initiated formation of the
numerous and widespread breccia pipes in the region.

Exploration

Denison did not carry out any exploration on the properties
since the acquisitions in 1997 and 2007, respectively, nor has the Company to
date. Please see Historyabove for information on historic drill
programs.

Mineralization

In the breccia pipe deposits, uranium occurs largely as blebs,
streaks, small veins, and fine disseminations of uraninite/pitchblende.
Mineralization is mainly confined to matrix material, but may extend into clasts
and larger breccia fragments, particularly where these fragments are of Coconino
sandstone. In addition to uranium, an extensive suite of elements is reported to
be anomalously concentrated in mineralized rock within breccia pipes throughout
northern Arizona. Within many pipes, there is a definite mineralogical zoning in
and around the uranium ore body.

The breccia pipes are surrounded by bleached zones,
particularly notable in the Hermit Formation where unaltered red sediments
contrast sharply with grey-green bleached material. Both age dating and
disequilibrium determinations indicate that remobilization of uranium has
occurred. Uranium concentrations in the upper levels of a deposit tend to be in
equilibrium, but with depth disequilibrium in the ore bodies increases in favour
of the chemical assays.

Uranium mineralization within Arizona 1 extends significantly
in the vertical dimension. Continuous drill hole intersections of several tens
of feet with grades exceeding 1.00% eU3O8 or more are not uncommon. The maximum
continuous surface drill hole intersection was 92.5 feet at an average grade of
1.55% eU3O8. On average, the 17 drill holes from surface which had intersected
uranium mineralization recorded 75 feet of 0.62% eU3O8.

Uranium mineralization at the Pinenut deposit includes ore
bearing intercepts, the uppermost of which is at an elevation of 4563 ft. above
sea level (depth from surface = 879 ft.); and the lowermost of which occurs at
4074 ft. (1,372 ft. depth)

67

---

The uppermost part of the mine consists of several isolated ore
bodies which may be associated with a ring fracture system. Other, less
prolific mineralized material occurs within the pipe body proper but remains
isolated and sporadic down to elevation 4440 ft.

Below 4440 ft. elevation and to the bottom of the
mineralization the central part of the ore body remains consistent. At its
widest it measures 220 ft. in long dimension and 140 ft. in short dimension.
This main section tapers slowly down to dimensions 100 ft. by 40 ft. at an
elevation of approximately 4220 ft., below which historical mining has removed
all ore grade material.

Uranium mineralization at Canyon is concentrated in three
stratigraphic levels: Coconino, Hermit/Esplanade, and a lower zone.
Mineralization extends vertically from a depth of 600 feet to over 2,100 feet.
Intercepts range widely up to several tens of feet with grades in excess of
1.00% eU3O8. Twenty-two drill holes from surface encountered uranium
mineralization averaging 100 feet of 0.45% eU3O8.

Uranium mineralization in EZ1 occurs at two distinct vertical
intervals. The Upper zone is contained within a 400-foot interval 1,170 to 1,560
feet below surface and at its widest point has a diameter of approximately 183
feet. The Lower zone is at a depth of 1,812 to 2,143 feet and at its widest
point has a diameter of 45 feet. At EZ2, the mineralization occurs in three
distinct zones: an Upper, Middle and Lower zone. The larger Upper zone is
mushroom shaped and is approximately 300 feet wide at its widest point and
occurs from 952 feet to 1,153 feet below surface. The Middle zone is made up of
two central deposits surrounded by multiple ring deposits. The Middle zone array
of deposits occurs between depths of 1,194 to 1,356 feet. The Lower zone also is
a mushroom shaped deposit from 1,417 to 1,512 feet.

Drilling

Shallow drilling was often conducted to locate the centre of
the collapse feature as a guide to the throat of the underlying breccia pipe.
The basic tool for exploring breccia pipes in northern Arizona is deep rotary
drilling supplemented by core drilling, to a depth of 2,000 feet or more from
surface. Prospective pipes were usually first tested with three drill holes. If
no mineralization was present, the effort was abandoned.

Exploration drilling of breccia pipes is a difficult process.
Substantial depths, approximately 2,000 feet, small targets, approximately 200
feet in diameter, and non-homogeneous rock formations combine to limit the
accuracy of the drilling process. The presence of cavernous and brecciated
sediments near the present land surface can result in loss of circulation of
drilling fluid; as a result, much drilling is conducted blind. Periodic spot
cores are taken to determine whether or not holes are within the target
structure or have drifted away from the pipe. Indeed, most pipes cannot be
completely drilled out from the surface due to deviation from desired targets.
All drill holes are surveyed for deviation and logged with gamma logging
equipment.

If surface drilling provides sufficient encouragement that a
mine can be developed, on that basis a vertical shaft is sunk or drilled to its
ultimate depth and underground drill stations are established at various levels
to provide platforms for further exploration and delineation drilling. Drilling
from underground stations typically utilizes large bore percussion drills. The
resulting drill holes, out to as much as approximately 300 feet or so, are then
gamma logged and surveyed as a supplement to surface drilling.

Energy Fuels drilling activities at the Arizona 1 and Pinenut
mines have focused on underground drilling. No recent drilling has occurred at
the Canyon or EZ properties.

EFN explored the Arizona 1 pipe with a total of 253 drill
holes, including: 18 core holes from underground drill stations with a total
footage of 6,122 ft.; 17 rotary holes from surface with a total footage of 25,289 ft., and 218 long holes from underground
drill stations with a total footage of 36,189 ft. Thus, total drill footage
drilled at Arizona 1 amounts to about 67,600 ft. Mine development of the Arizona
1 deposit began in 1990 but was suspended in 1992, with the shaft at a depth of
1,254 ft. Denison recommenced development work on the Arizona 1 deposit in April
2007 and restarted mining operations in 2009 when the air quality permit was
received. The Canyon deposit is located on mining claims that EFN acquired from
Gulf Mineral Resources Company (Gulf) in 1982. Gulf drilled eight
exploration holes at the site from 1978 through May 1982 but found only
low-grade uranium in this pipe. Additional drilling completed by EFN in 1983
identified a major deposit. EFN drilled a further 36 holes from May 1983 through
April 1985 to delineate the uranium mineralization and to determine placement of
the mine shaft and water supply well. Additional drilling of six holes was
completed in 1994.

Sampling Method and Approach

All the historical drill holes on Energy Fuels Arizona Strip
breccia pipe properties were gamma logged and surveyed for deviation. These data
provide the basic building blocks from which quantities of mineralized material
are estimated. Core holes were drilled to supplement this data, to provide
information for determination of disequilibrium, and to accommodate material for
metallurgical testing. This process was consistent with industry standards at
the time and the work carried out by EFN is judged by RPA to have been of
superior quality.

All of the basic data for calculation of quantities and grades
of mineralized material for the Arizona 1, Pinenut, Canyon, and EZ1 and EZ2
deposits was derived directly by gamma log interpretation. Numerous checks were
completed on this data by means of chemical assays, closed-can assays, and
various beta gamma analyses.

RPA noted in the two technical reports that all gamma log
grades listed and discussed utilize an eU3O8 characterization. The e preceding
U3O8 indicates that the respective grades are equivalent U3O8grades based on an assumed direct correlation between gamma-ray intensity,
as measured by the gamma logging tools, and uranium content. Such is not always
the case and the correlation must always be checked by chemical and radiometric
assays of core samples or by direct neutron activation means. EFN performed
extensive checks on core and the available results seem to confirm the general
correlation, but detailed test results are not available for review. In laymans
terms, the e prefix indicates that somewhat less reliance can be placed on the
reported grades than if sufficient data was available to provide greater
assurance on the correlation. It is at least partially for this reason that
Mineral Resources listed herein are classified as Inferred.

Industry standards for uranium exploration in the western
United States are based almost completely on the gamma logging process with a
number of checks, including: (i) frequent calibration of logging tools, (ii)
core drilling and chemical analysis of core as a check on gamma log values and
the potential for disequilibrium; (iii) possible closed-can analysis as an
adjunct to chemical assays; and (iv) possible gamma logging by different tools
and/or companies.

EFN used the GAMLOG computer program to interpret gamma-ray
logs. The GAMLOG program was developed by the AEC. The essence of the method is
a trial and error iterative process by which U3O8 grades are determined for a
series of 1/2-foot or 1-foot layers which can be considered to comprise the zone
under analysis. The objective of the iterative process is to find a grade for
each separate layer such that an imaginary set of separate gamma-ray anomalies
(one from each separate layer) could be composited to form an overall anomaly
which would closely match the real anomaly under analysis. Data verification in
uranium exploration in the western United States takes the form of a combination
of logging tool calibration, chemical assays on core, and various checks by
other logging units and outside laboratories. Most of this verification process
is internal and company specific. Independent verification has not been part of the industry standard process. EFN
operations in the Arizona Strip were judged by RPA in both technical reports to
have met or exceeded industry standards. Complete sets of basic drill hole data,
such as gamma logs and chemical assay data for the Arizona 1, Canyon, Pinenut
and EZ breccia pipe deposits, were not available for RPAs inspection. However,
some of the gamma logs and chemical assay data that were available for
inspection by RPA confirm the validity of a vast majority of these data. The
checks by RPA included reinterpretation of selected gamma logs and comparison of
chemical assay data with log interpretations. Certain items of data could not be
confirmed due mainly to lack of a complete set of chemical assay data for core
holes. Notwithstanding the foregoing, most mismatches in data or interpretation
seemed to err on the conservative side; i.e., lower grade, less tons, fewer
pounds. RPA noted, however, that for the Arizona 1 deposit, where substantial
information is available from both surface and underground drilling, the two
data sets show a pattern of divergence, with surface gamma log results showing
generally higher values than gamma log results for the underground drilling.
Certainly, the surface gamma logging tools and procedures were in all respects
standard for the period, with no major bias expected. Nevertheless, a comparison
of available chemical assay data with gamma log interpretations suggests the
possibility of overestimation of uranium grades by surface hole gamma logs. This
potential overestimation is tempered somewhat by questions from EFN personnel
concerning the validity of chemical assays for this particular data set.
Re-assay data available to RPA do not seem to diverge greatly from the original
data. Underground gamma logging at Arizona 1 is understood to have utilized
newly developed tools which may or may not have been as well calibrated as the
surface tools. Given, however, that the underground gamma results are generally
lower than the surface gamma results, any potential bias seems to be
conservative. Thus, surface gamma data at Arizona 1 is not fully supported by
either underground data or by chemical assay data. A potential exists,
therefore, that grades developed by surface gamma logging could be overstated.
The situation is reversed at both Canyon and Pinenut where available data
indicate substantial grade understatement by gamma logging in comparison to
chemical assays. Available chemical assay data at Canyon and Pinenut show
chemical grades to be in the order of 60% higher than gamma logging grades. It
should be stressed that chemical assay data for all pipes is incomplete,
unverified and, in some cases, conflicting. This situation contributes
substantially to the use of an Inferred classification for Mineral Resources
within all pipes. RPA concludes that, although not all data were available for
checking, EFN followed standard industry practices of the time and that the
results of those practices are likely to be a reasonable guide to mineralization
available for resource estimation and exploitation. RPA is of the opinion that
available data are insufficient to make a definitive judgment on the differences
between gamma values and chemical assays. We recommend that Energy Fuels attempt
to pursue these discrepancies in greater detail in order to clarify the
situation.

Security of Samples

There are no specific provisions for security of data or
samples other than those employed for confidentiality. The previous property
owners are deemed to have met or exceeded industry standards for the exploration
process.

Mineral Resource and Mineral Reserve Estimates

Initial Mineral Resource estimates were prepared for the
Arizona 1, Canyon, Pinenut and EZ Complex deposits using historical drill hole
data provided by Energy Fuels. RPA interpreted a set of cross sections and plan
views to construct 3-D grade-shell wireframe models at 0.2% eU3O8. Variogram
parameters were interpreted and eU3O8 grades were estimated in the block model
using kriging. The grade-shell wireframes were used to constrain the grade
interpolation. All blocks within the 0.2% eU3O8 grade-shell wireframes,
regardless of grade, were included in the Mineral Resource estimate. There are
no Mineral Reserves estimated at any of the five deposits at this time. In June
2012, RPA estimated the Inferred Mineral Resources as shown below.

    The Arizona 1 Mine was placed on standby in
      February 2014 due to the depletion of the economic resources.


The Mineral Resource estimates for the EZ1, EZ2, and Canyon
mines may be materially affected by with mineral withdrawal described in
Energy Fuels Business  Government Regulations  Land Tenure below. In
the event the EZ1, EZ2, and/or Canyon properties are found to not have valid,
existing rights, the Mineral Resource estimates for those properties may be
reduced to zero.

Cut-off Grade

In its feasibility studies of the various Arizona Strip breccia
pipes compiled during the 1980s and 1990s, EFN typically used a cut-off grade of
0.15%U3O8.A reasonable cut-off grade for long
term sustainable market conditions would be approximately 0.20% U3O8. This
cut-off grade was applied by RPA to all the breccia pipe deposits.

Mineral Resource and Reserve Update

Since the Mineral Resource estimates were prepared by RPA, the
Mineral Resources have been updated for the Pinenut and Canyon operations by the
Company. Furthermore, at Arizona 1, mining operations have been underway since
late 2009. In February 2014, the Arizona 1 Mine was placed on standby due to the
depletion of the economic resources. As a result of the updates and the mining
operations, the following illustrates the current Mineral Resource estimates for
the Arizona Strip properties.

The Arizona 1 Mine was substantially developed in the 1990s
with the production shaft completed to 1,250 feet of the proposed final 1,650
foot depth. Drill stations were cut near the current shaft bottom, and about
40,000 feet of drilling was completed from those stations. The previous owner
decided to ramp down from the bottom of the existing shaft rather than deepen
the shaft to access the lower parts of the ore body. A headframe, hoist and
compressor are in place. As of February 2014, ore production at Arizona 1 has
been placed on standby due to the depletion of the economic resource.

The Arizona 1 deposit was mined using a combination of long
hole and shrinkage stoping methods at a mining rate of up to 300 tons per day,
four days per week. In 2010, Arizona 1 produced approximately 21,500 tons at an
average grade of 0.56% U3O8, in 2011 produced 39,900 tons at an average grade of
0.66% U3O8. Subsequent to the Technical report, production in 2012 amounted to
about 30,300 tons at an average grade of 0.62% U3O8. In calendar 2013 the mine
produced almost 16,300 tons at a grade of 0.58% U3O8. From 2009 through December
31, 2013 the Arizona 1 Mine has produced 107,936 tons at an average grade of
0.615% U3O8, containing approximately 1,327,500 lbs U3O8. An additional 3,651
tons of ore were produced in early 2014, prior to the mine being placed on
standby on January 28, 2014. There will remain an estimated resource of
approximately 26,000 tons at a grade of 0.257% eU3O8for 134,000 lbs. uranium. The
mine is now on care and maintenance.

The Pinenut Mine is a producing underground uranium mine. The
Pinenut Mine was partially developed in the late 1980s, and a limited amount of
selective mining was conducted. A shaft was sunk to a depth of 1,350 feet and a
high grade pod was mined in late summer 1988, yielding 25,500 tons grading 1.03%
U3O8containing 526,000 pounds. Following extraction of the high grade pod, the
mine was placed on standby in 1989. In November 2010, a production decision was
made on the Pinenut Mine. Expansion of the storm water storage pond and
rehabilitation of the surface facilities were completed in 2011. Following
filing of the Technical Report, first ore production resumed in June 2013. From
the resumption of mining to the end of calendar year 2013, production amounted
to about 7,700 tons at an average grade of 0.527% U3O8.Uranium production is
expected to total approximately 693,000 pounds U3O8.The amount expected to be
produced in FY 2014 is 84,000 pounds.

The Canyon Project is a fully-permitted and partially-developed
uranium mine. Surface facilities were constructed in 1986, and the shaft was
collared and sunk to approximately 50 feet, prior to the mine being placed on
standby in 1992. After the Technical Report was written, Energy Fuels resumed
development of the Canyon Project in 2013. Activities included refurbishment of
the evaporation pond and recertification of site mechanical and electrical
installations. Shaft sinking begin in February 2013, with a total of 224 feet of
shaft advanced during FY 2013. The development was stopped in November 2013 due
to the continuing low market price of uranium and a stipulation entered into
with the Plaintiffs in a case challenging the Canyon Project. See Legal and
Regulatory Proceedings  Canyon Projectbelow.

The Kanab North mine remains on care and maintenance and a
closure plan has been approved for reclamation of the mine site. Reclamation is
currently underway.

There are no infrastructure or mining operations in place at
the EZ Complex or other of Energy Fuels Arizona Strip properties.

Permitting

Prior to 2009, the Arizona 1 Mine had received all permits
necessary to mine, with the exception of an air quality permit. The air quality
permit was issued by the Arizona Department of Environmental Quality
(ADEQ) after a period of public comment in September 2009. This permit
is expected to be renewed in 2014. The Arizona 1 Mine has an Individual Aquifer
Protection Permit with ADEQ and an approved PO with the BLM. A National
Emissions Standards for Hazardous Air Pollutants (NESHAPs) application for radon
emissions was submitted to the EPA in April 2013 when it became apparent that
the life of mine ore production would exceed the exemption threshold of 100,000
tons. The application was approved by the EPA on July 1 2013.

The Pinenut Mine and Canyon Project are located on public lands
managed by the BLM and USFS, respectively. Both mines have approved POs with
these agencies. In September 2009, the groundwater General permits were received
for the stormwater storage ponds for both mines. Air Quality Permits for the
Pinenut and Canyon projects were issued by ADEQ in March 2011. EPAs approval of
the Pinenut Mine NESHAP for radon emissions was obtained in April 2011.

The BLM had previously accepted the PO for the EZ1/EZ2 deposits
as complete; however, the PO is currently being revised to reflect a new mining
plan in which the EZ1 deposit will be mined first rather than concurrently with
the EZ2 deposit. The revised PO will need to be determined complete by the BLM
and a Mineral Examination will need to be completed by the BLM for the project
before an Environmental Impact Study (EIS)can be initiated.

In July 2009, the BLM issued a Notice of Proposed Withdrawal
(2009 Notice). See Government Regulation  Land Tenure  United
States below. In January 2012, the Secretary of the Interior implemented
the withdrawal of approximately one million acres of public land in the Arizona
Strip from mineral entry proposed in the 2009 Notice, subject to valid existing
rights. To confirm the rights to proceed with development and mining on its
existing valid rights, the USFS completed a Mineral Examination for the Canyon
Project, which confirmed that the mineral claims underlying the Canyon Project
are valid existing rights. Mineral examinations have been completed on the
Arizona 1 and Pinenut mines as well. Mineral examinations need to be completed
by the BLM for the EZ Complex and other = Company projects within the withdrawal
area, prior to further permitting on those projects.

Metallurgical Testing

Mill amenability tests on mineralized material from core
drilling at Arizona 1 prior to 1993 indicated that 96% extraction could be
attained with a leach retention time of 48 hours. Acid consumption was 540
pounds per ton of material with the addition of 1.75 pounds of sodium chlorate.

Test work completed on samples from the Canyon pipe during 1984
indicated 99% leach extraction with 25 g/l of free acid at a pH of 0.8. Leach
retention time was 48 hours at 70oC with a sodium chlorate addition of 16 pounds
per ton.

Details on Pinenut amenability were not available at the time
of the Arizona Strip Technical Report, but some 25,800 tons of material at an
average grade of 1.02% U3O8 from Pinenut were processed at the White Mesa mill
at Blanding, Utah, during 1989 and 1990. On the basis of the results from that
milling, EFNI expected to recover 96% of the uranium contained in the remaining
material.

---

Mining Methods

The Arizona 1 and Pinenut deposits are mined using a
combination of long hole and shrinkage stoping as described in Section 6
History contained in the Arizona Strip Technical Report. The Pinenut mine is
projected to operate through the 2ndquarter of 2014, at which time
the project is likely to be placed on standby. The Arizona 1 Mine was placed on
standby in February 2014 due to the depletion of the economic resources.

Recovery Methods

All mineralized material produced from the Arizona 1, Pinenut
and Canyon deposits on the Arizona Strip will be processed at Energy Fuels
White Mesa mill at Blanding, southeastern Utah. The White Mesa mill is located
six miles south of Blanding. EFNI anticipated reopening of many small low-grade
mines on the Colorado Plateau, and the mill was designed to treat 2,000 short
tons of ore per day. Construction commenced in June 1979 and was completed in
May 1980. Due to uranium market variability, the mill has frequently operated on
a campaign basis in order to provide intervals for stockpiling sufficient ore to
operate the mill at capacity. Treatment of higher grade ores from the Arizona
Strip required certain minor modification to the leaching circuit and is at a
rate somewhat lower than nominal capacity. The basic mill process is a sulphuric
acid leach with solvent extraction recovery of uranium and vanadium. Run-of-mine
ore is reduced to minus 28 mesh in a six-foot by 18-ft. diameter semiautogenous
grinding (SAG) mill. Leaching of the ore is accomplished in two stages:
a pre-leach and a hot acid leach. The first, or pre-leach, circuit, consisting
of two mechanically agitated tanks, utilizes pregnant (high-grade) strong acid
solution from the countercurrent decantation (CCD) circuit which serves
both to initiate the leaching process and to neutralize excess acid. The
pre-leach circuit discharges to a 125-ft. thickener where the underflow solids
are pumped to the second stage leach and the overflow solution is pumped to
clarification, filtration, and solvent extraction circuits. A hot strong acid
leach is used in the second stage leach unit, which consists of seven
mechanically agitated tanks having a retention time of 24 hours. Free acid is
controlled at 70 grams per litre and the temperature is maintained at 75°C.
Leached pulp is washed and thickened in the CCD circuit, which consists of eight
high capacity thickeners. Underflow from the final thickener at 50% solids is
discharged to the tailings area. Overflow from the first thickener (pregnant
solution) is returned to the pre-leach tanks. The solvent extraction (SX)
circuit consists of four extraction stages in which uranium in pregnant solution
is transferred to the organic phase, a mixture consisting of 2.5% amine, 2.5%
isodeconal, and 95% kerosene. Loaded organic is pumped to six stages of
stripping by a 1.5 molar sodium chloride solution, and thence to a continuous
ammonia precipitation circuit. Precipitated uranium is settled, thickened,
centrifuged, and dried at 1,200°F. The final product at about 95% U3O8 is packed
into 55-gallon drums for shipment.

Current and Contemplated Exploration and Development
Activities

Energy Fuels plans to continue mining at the Pinenut mine until
mid-2014, at which time the mine is expected to be placed on standby. No
additional exploration activities are expected at this project. Sustaining
development is expected to continue to occur.

At the Canyon Project, shaft-sinking activities were placed on
standby in November 2013. Pursuant to a stipulation entered on litigation
occurring in connection with the Canyon Project, the Company has agreed to not
perform any shaft sinking activities until December 31, 2014, or such time that
a decision on the merits of the litigation has been rendered by the District
Court. The Company expects to maintain the surface facilities on care and
maintenance. The Company is not planning to perform any exploration activities.

At the Arizona 1 Mine, ore production has ceased due to the
depletion of the economic resource. The Company plans to complete additional
drilling to determine if additional resources remain on the property. If not,
the mine will be placed into reclamation.

The Company will continue permitting and assessment activities
at the EZ Complex. The BLM is currently conducting a Mineral Examination of the
project, which has to be completed before preparing an EIS.

The Daneros Mine

Unless otherwise stated, the following description of the
Daneros Mine is derived from a technical report entitled The Daneros Mine
Project, San Juan County, Utah, U.S.A., dated July 18, 2012, prepared by
Douglas C. Peters, Certified Professional Geologist, of Peters Geosciences,
Golden, Colorado in accordance with NI 43-101 (the Daneros Mine Technical
Report). The author of the Daneros Mine Technical Report is a qualified
person and is independent of the Company within the meaning of NI 43-101. The
Daneros Mine Technical Report is available on SEDAR at www.sedar.com.

Project Location and Description

The Daneros Mine is located in the White Canyon District, which
is an historic uranium district located in southeastern Utah within the Colorado
Plateau District. The White Canyon District generally encompasses the local
geographic areas of Red, White and Fry Canyons, and Elk Ridge along State
Highway 95 between Blanding and Hite, Utah. Energy Fuels holds a 100% interest
in various groups of mining claims and SITLA Leases comprising its White Canyon
District holdings, including the Daneros Mine and adjoining historical mine
sites, such as the Spook, Bullseye, Lark and Royal properties, which can be
developed in conjunction with the Daneros project. The White Canyon District
holdings also include the Companys exploration properties named Geitus,
Hideout, Blue Jay, and Marcy Look.



The total acreage of the project area is 4,300 acres. The
mining claims are maintained by making annual payments of US$140 per claim to
BLM due September 1st each year and a nominal filing fee at the county level,
within 30 days of the BLM filing, of about $10 per claim. Work expenditures are
not required. Holders of unpatented mining claims are generally granted surface
access to conduct mineral exploration and mining activities. Unpatented mining
claims expire annually, but are subject to indefinite annual renewal by filing
appropriate documents and paying the fees described above. However, additional
mine permits and plans are generally required prior to conducting exploration or
mining activities on such claims. EFIs holdings in the White Canyon District
include the actively producing Daneros Mine and adjoining and nearby exploration
properties.

A number of the claims bear production royalties. Claims
hosting Daneros deposit are subject to royalties ranging between 15% of "market
value" of the ore and 2.5% of gross proceeds as described in further detail in
the Daneros Mine Technical report. Other claims are owned by EFI without
encumbrances.

The Daneros Mine portal area is accessed by a gravel-covered
side road off of Radium King Road (a county-maintained gravel road). The mine
facilities consist of a modular trailer for the mine office, two reinforced mine
portals, a generator building, and an equipment storage and maintenance
building. Two ventilation shafts daylight on the topographic bench above the
mine. The bench above the mine, where past drilling also had been conducted, is
accessed by a dirt road connecting to the mine access road south of the mine
portal area.

Please see Mineralization section below for the
location of all known mineralized zones and mineral resources. Please see
Permitting section below for the current status of permitting and
approvals for the project.

Accessibility, Climate, Local Resources, Infrastructure and
Physiography

The Daneros Mine is located 4.8 miles from Fry Canyon, Utah and
is accessed via Radium King Road for approximately 14 miles, which is maintained
by San Juan County. The Daneros Mine was developed and placed into active
production by Utah Energy Corporation (UEC), the U.S. operating entity
for WCUL at the time (both UEC and WCUL are now wholly-owned subsidiaries of
Energy Fuels with UEC now known as EFR White Canyon Corp., and WCUL in the
process of being deregistered). The ore shipping distance from Daneros to the
Companys White Mesa Mill is 65 miles along county roads and state highways.

The semi-arid climate of the White Canyon area is characterized
by large daily and yearly temperature ranges and total annual precipitation of
approximately 10 to 16 inches, mostly as sporadic, intense summer thunderstorms
typical of the Colorado Plateau region. Winter snowfall is moderate and rarely
stays on the ground very long. Weather conditions pose no impediment to year
round work on the property.

Apart from previous mining activities, the only commercial land
use purposes are cattle grazing and tourism activities such as hiking and
mountain biking. Due to a shortage of water and thin soils, much of the White
Canyon area is unsuitable for agriculture.

The project area is remotely located relative to water and
power infrastructure. Housing for mine workers is mostly in camp trailers in Fry
Canyon or they commute from Blanding, Utah 65-miles to the east or farther.
Blanding is a town large enough to host regional industrial activities including
stores and supply houses of sufficient size and inventory to meet most of the
needs of an operation the size of the Daneros mine.

The project area is located along a north-south trending canyon
which is a tributary to Red Canyon, also known as Bullseye Canyon. The Red
Canyon drainage flows westerly for approximately 25 miles to the Colorado River
where it joins Lake Powell at the head of Good Hope Bay. The mine portal area
comprises steeply sloping, rocky ground and scree along the eastern slope of
Bullseye Canyon. Very steep to vertical, and at times overhanging, cliffs 400
feet high rise from the slope about 250 feet above the portal.

Vegetation in the project area consists of sagebrush, juniper
and piñon in the hills and slopes, while desert grasses, forbs, and shrubs are
evident within the valley floors and on the mesa tops. Elevations in the region
range from about 5,300 feet at the Fry Canyon townsite to over 7,000 feet on the
surrounding mesa tops. The mine portal is at about 5,750 feet above sea level.

Sufficient surface rights are in place for contemplated mining
operations and waste storage. Since no milling activities are contemplated on
the project, no areas are required for tailings storage, heap leach pads, or
processing plant sites.

History

The White Canyon mining district has a long history of
exploration and mining. From 19491987 production from the district was
2,259,822 tons at an average grade of 0.24% U3O8 for
a total of 11,069,032 lbs. placing it second, behind Lisbon Valley, for
uranium production from the Chinle Formation on the Colorado Plateau.

Prospecting for copper in the White Canyon area is thought to
have begun possibly as early as 1880 by early gold prospectors. During 1906 and
1907 there was intense activity for copper exploration in the area when there
was an unusually high price for copper, but no production resulted. The
properties in the area remained idle again until 1946 when miners shipped two
truckloads of copper ore from the Happy Jack Mine to a smelter in Garfield, Utah
but they were rejected due to uranium content. In 1948 a truckload of ore was
sent to the U.S. Atomic Energy Commission (AEC) Mill in Monticello,
Utah and it was rejected due to its copper content. In August 1949 Vanadium
Corporation of America (VCA) began operating a small mill in White
Canyon that could recover copper and uranium and that opened up uranium mining
in the White Canyon area. From 1948 until 1951, White Canyon and the nearby Red
Canyon and Deer Flat areas were subject to intense exploration. Production
slowly increased until 1953 when it nearly tripled over previous years. The AEC
White Canyon Mill was closed in December 1953 and producers started shipping to
an ore buying station built by the AEC in 1954 on a site near the Happy Jack
Mine. The number of active mines during 1954 in the White Canyon District
increased from 19 to 36. On July 31, 1957, the AEC closed its White Canyon
Buying Station after purchasing 179,635 tons of ore averaging 0.25% U3O8 and
containing 915,696 pounds U3O8. The stockpiled ore was later sold to Texas-Zinc
Minerals Corporation (Texas-Zinc).

In the summer of 1956, Texas-Zinc began operating their mill at
Mexican Hat, Utah. The mill initially processed 775 tons of ore per day and was
expanded to 1,000 tons per day in 1958. Due to changes in the AEC buying
program, reducing its procurement program, production in the district started to
decline in 1959. In June 1959, five uranium companies were merged to form Atlas
Minerals, a subsidiary of Atlas Corporation. Atlas Minerals acquired Texas-Zinc
Minerals in July 1963 and continued to operate the Mill in Mexican Hat through
its subsidiary, A-Z Minerals Corporation. Due to reduced buying by the AEC AZ
Minerals closed the Mexican Hat Mill in February 1965. The closing of the
Mexican Hat Mill and previous closing of the AEC ore-buying station and closing
of the AEC facility at Monticello, Utah, left the independent operators in the
district with the only market for their low-vanadium ores at the Atlas Minerals
mill at Moab, Utah, a 110-mile longer haulage which caused production to
continue its decline. The AEC ore procurement program ended on December 31, 1970
and during the early 1970s minimum production was recorded from the district.
Production from the district started picking up again by 1974 when the demand
for uranium picked up due to nuclear power generation. Atlas Minerals started
buying ore from independent producers. Exploration and production once again
increased in the White Canyon District. In 1974, Utah Power and Light Company
(UP&L) began to acquire properties in the White Canyon District, which
included 100% interest in the Spook-Bullseye property and 60% interest in the
Lark-Royal property both located near the Daneros property in Red Canyon.
UP&L conducted exploration drilling from 1975 through 1983, drilling a total
of 2,417 holes, which resulted in the discovery of several new uranium deposits.
UP&L never started mining operations in the White Canyon District due to the
collapse of the uranium price by 1982. By 1987 the last mines in the White
Canyon district closed due to declining economics, socio-political factors and
competition from lower cost producers. Following 1987, the properties were idle
and little or no exploration activity took place in the White Canyon District.
In 1993 UP&L dropped their mining claims in the White Canyon District. In October 1993, Eugene and Merwin Shumway staked the Daneros and
Geitus claims that covered two of the deposits UP&L had discovered. Eugene
and Merwin Shumway quitclaimed their claims to predecessors of White Canyon
Uranium (WCU), Wilene and Mike Shumway, Terry Leach, and James Lammert in March,
1994. No exploration or development took place between 1994 and 2005. From 2005
to 2007, these predecessors of WCU began acquiring properties with known
historic mineral deposits in the White Canyon District. In 2007, Utah
Commodities Pty, Ltd. who later changed their name to White Canyon Uranium
Limited, which operates in the United States through its wholly owned subsidiary
Utah Energy Corporation, acquired 100% interest of the Daneros and Geitus
claims. In December 2008, White Canyon purchased 33 claims, known as the
Lark-Royal Project, an extension of the Daneros Project, from Uranium One.

Between 1975 and 1985, Utah Power & Light conducted several
phases of drilling leading to definition of the Lark, Royal, and Bullseye
deposits near the modern day Daneros Mine. Following the Utah Power & Light
era, the properties were idle and little or no exploration activity took place
in the White Canyon District. With the resurgence in the uranium market in the
2005  2007 period, predecessors of WCUL began acquiring properties, with known
historic mineral deposits, in the White Canyon District. After consolidating a
portfolio of properties and prospects, WCUL initiated confirmation and
definition drilling at the Daneros Mine in June 2007. Based on the success of
this initial drilling, 38 more holes were drilled in 2008, providing the basis
for mineral resource estimates relied upon by WCUL to commence mine development
work at Daneros.

In January 2010, Denison entered into a toll milling agreement
with UEC, which was then a wholly-owned subsidiary of WCUL. See Energy
Fuels Business  Operations  Ore Purchase and Toll Milling above.

In 2011, Denison acquired all of the issued and outstanding
shares of WCUL. In June 2012, Energy Fuels acquired all of the issued and
outstanding shares of WCUL as part of its acquisition of the US Mining Division,
including the Daneros Mine and WCULs subsidiary UEC (which is now called EFR
White Canyon Corp.)

The assets of UEC are comprised of all of its mining claims and
mineral leases in Utah, which includes 547 claims and five Utah state leases,
totaling about 5,670 hectares (14,000 acres), all in southeastern Utah. The land
holdings of the Company in the White Canyon District include 341 unpatented
mining claims and two SITLA Leases, in total about 3,000 hectares (7,400 acres).
Mining claims are maintained by making annual payments of $140 per claim, and
the SITLA Leases generally cost $1 per acre annually.

A number of the properties bear production royalties. Claims
hosting a portion of the Daneros Mine are subject to royalties ranging between
15% of market value of the ore and 2.5% of gross proceeds. A portion of the
area mined in 2012 was free of any royalty. The exploration properties also have
royalties in some cases, including SITLA Leases which provide for royalties of
8% on uranium and 4% on vanadium.

Geological Setting

Major uranium deposits of the east-central Colorado Plateau
District occur principally in two fluvial sandstone sequences. The older is
located at or near the base of the Upper Triassic Chinle Formation and the other
occurs in the Late Jurassic Salt Wash Member of the Morrison Formation. Nearly
all of the ore deposits in the White Canyon District occur in fluvial channel
deposits of the Shinarump Member of the Chinle Formation.

79

---

The Shinarump Member consists of predominantly
trough-crossbedded, coarse-grained sandstone and minor gray, carbonaceous
mudstone and is interpreted as a valley-fill sequence overlain by deposits of a
braided stream system. Uranium mineralization appears to be related to
low-energy depositional environments in that uranium is localized in fluvial
sandstones that lie beneath organic-rich lacustrine-marsh mudstones and
carbonaceous delta-front sediments. The reducing environment preserved in these
facies played an important role in the localization of uranium.

Exploration

The White Canyon District includes unpatented mining claims and
SITLA Leases covering historical mineral deposits in the Elk Ridge and Deer
Flats areas. Exploration Notices for surface drilling were obtained by UEC for
the Geitus, Blue Jay, and Marcy Look areas. Energy Fuels is evaluating historic
information on these areas to assess plans for exploration drilling.

Exploration Notices have also been approved for brown fields
drilling around the Daneros mine. These Notices cover the Daneros and the Lark
and Royal claim areas. Energy Fuels is reviewing plans for additional surface
drilling in the Daneros mine area.

Mineralization

Uranium deposits consist of closely-spaced, lenticular ore pods
which are generally concordant with bedding in paleochannel sediments. Single
ore pods range from a few feet to a few hundred feet in length and from less
than one to more than 10 feet in thickness. Deposits range in size from a few
tons to more than 600,000 tons. The Shinarump deposits generally have low
vanadium content, and are therefore not processed for vanadium recovery.
Historical production from the White Canyon District exceeds 11 million pounds
U3O8.

The ore production from Daneros for 2010, 2011 and 2012 is
shown below:

Energy Fuels placed the Daneros mine on standby on October 17,
2012, pending improvements in commodity prices. It remained in that status
throughout 2013.

Drilling

Between 1975 and 1985 Utah Power & Light (UP&L)
explored within and around Bullseye Canyon area resulting in a number of
promising uranium discoveries. The area in and around Bullseye Canyon, where
Daneros is located, has been a target of this exploration drilling since that
time. Also during the AEC exploration programs, companies were encouraged to
mine exploration drifts along promising geologic trends or channels. As part of
this exploration drifting, a company would drill exploration long-holes
underground, to better define a chosen mineralized zone. Several of these
prospects around the EFI property were drilled in this manner. The Spook
Prospect, the Bullseye Prospect and the Cove (Lark) Prospect were all mined and
drilled in this manner along the Cairns Channel (Texas Zinc and Minerals Map of 1961). Between 1975 and 1985 Utah Power & Light
(UP&L) explored within and around Bullseye Canyon. UP&L drilled 595
diamond drill holes with an average depth of 510 feet and, following industry
standard procedures, logged all holes using down-hole geophysical (gamma) probes
to identify radioactive horizons. Anomalous horizons were sampled and analyzed
for uranium. WCU began drilling programs in Bullseye Canyon during 2007. The
first program drilled 8 holes within the five Daneros claims. A second program,
in 2008 drilled 16 diamond drill holes and 1 rotary drill hole. Finally, a third
program, also in 2008, drilled 11 diamond drill holes and 9 rotary drill holes.

Energy Fuels received an electronic database from WCUL
containing both the results of their recent drilling programs (Daneros holes) as
well as a spread-sheet containing name, location and interval grade data of the
historic UP&L data. The UP&L data were in the Utah State Plane
coordinate system (UT-S, NAD 27) and the Daneros collar data was in UTM Zone
12-S meters, NAD83. Energy Fuels maintains all its drilling, mining and survey
data in Utah State Plane NAD83, South zone feet for all its projects in southern
Utah. Therefore, it was necessary to convert all data, both recent and historic
to the current coordinate system. The database received contained a confusing
set of tables of these two data sets, as both datasets had had their drill hole
collars converted from state plane to UTM (by previous workers). Energy Fuels
used its own state certified surveyors to survey in the collars of as many of
the drill holes as they could find. All the DAN holes were easily found as well
as several of the historic drill hole collars on the east side of Bullseye
Canyon. The surveyed Daneros collars were compared to the surveyed collars
provided by WCU for the DAN drill holes and were found to agree. Energy Fuels
also received and electronic file; UPL_Drillholes_Formatted_Final_LK.xlsx
which contained the collar information for the UP&L drill holes in their
original coordinate system; UT-S. AutoCAD Civil 3D was then used to convert the
drill hole collars of the historic drill holes to the current coordinate system
and compared the results to the current survey of several historic drill hole
collars. After slight adjustments for rotation between the two state plane
coordinate systems, it was found that the converted drill hole collars fell
within two feet of the surveyed collars. Energy Fuels considers its conversion
method, as well as its survey method, sound, and as a result considers the
historic UP&L data set satisfactory for use in the Daneros Mine Technical
Report.

Energy Fuels has combined both the recent drilling by WCU with
the appropriate historic drill hole data from UP&L to create the database
used for the Daneros Mine Technical Report. All historic drill holes notin the immediate vicinity of the Daneros claim group have been removed from
consideration. No hard copy information could be found (drill logs) for the
historic UP&L drill hole data therefore the data could not be verified.
Energy Fuels imported the dataset into Vulcan 3D Mine Modelling software and ran
validation checks on the down hole data (repeating intervals, overlapping
intervals, increasing values, etc.) as well as the collars (2D checks for unique
coordinate locations and 3D checks for collars at the surface) and minimal
corrections were needed to make the data set sound. The data set was then used
to create the following resource estimate for the Daneros Prospect.

All down hole grade data used for the Daneros Mine Technical
Report is based on gamma probe results. Energy Fuels received the raw data file
for the Daneros drill hole set from Hawkins Geophysical. The data were processed
using Gamlog which converts cps (counts per second) data into equivalent eU3O8.
All factors affecting the gamma flux down hole are accounted for using the
Gamlog program and the results are industry standard acceptable.

Sampling and Analysis

Industry standards for uranium exploration in the western
United States are based almost completely on the gamma logging process with a
number of checks, including: 1) frequent calibration of logging tools, 2) core
drilling and chemical analysis of core as a check on gamma log values and the
potential for disequilibrium; 3) possible closed-can analysis as an adjunct to
chemical assays; and 4) possible gamma logging by different tools and/or companies. Energy Fuels used
the GAMLOG computer program to interpret gamma-ray logs. The GAMLOG program was
developed by the U.S. Atomic Energy Commission. The essence of the method is a
trial-and-error iterative process by which U3O8 grades aredetermined
for a series of 1/2-foot or 1-foot layers which can be considered to comprise
the zone under analysis. The objective of the iterative process is to find a
grade for each separate layer such that an imaginary set of separate gamma-ray
anomalies (one from each separate layer) could be composited to form an over-all
anomaly which would closely match the real anomaly under analysis. Energy Fuels
accepts the validity of the GAMLOG program. There are no specific provisions for
security of data or samples other than those employed for confidentiality. The
previous property owner, Denison Mines, is deemed to have met or exceeded
industry standards for the exploration program.

All uranium exploration technical information is obtained,
verified and compiled under a formal QA/QC assurance and quality control program
in the southwestern United States. The following details the protocols used by
all Energy Fuels staff and consultants.

Exploration for uranium deposits in the southwest United States
typically involves identification and testing of permeable sandstones within
reduced sedimentary sequences. The primary method of collecting information is
through extensive drilling and the use of down hole geophysical probes. The down
hole geophysical probes measure natural gamma radiation, from which an indirect
estimate of uranium content can be made. The radiometric (gamma) probe measures
gamma radiation which is emitted during the natural radioactive decay of
uranium. The gamma radiation is detected by a sodium iodide crystal, which when
struck by a gamma ray emits a pulse of light. This pulse of light is amplified
by a photomultiplier tube, which outputs a current pulse. The gamma probe is
lowered to the bottom of a drill hole and data is recorded as the tool is
withdrawn up the hole. The current pulse is carried up a conductive cable and
processed by a logging system computer which stores the raw gamma counts per
second (cps) data. If the gamma radiation emitted by the daughter products of
uranium is in balance with the actual uranium content of the measured interval,
then uranium grade can be calculated solely from the gamma intensity
measurement. Down hole cps data is subjected to a complex set of mathematical
equations, taking into account the specific parameters of the probe used, speed
of logging, size of bore hole, drilling fluids and presence or absence of and
type of drill hole casing. The result is an indirect measurement of uranium
content within the sphere of measurement of the gamma detector.

The basis of the indirect uranium grade calculation (referred
to as "eU3O8" or "equivalent U3O8") is thesensitivity of the sodium
iodide crystal used in each individual probe. Each probe's sensitivity is
measured against a known set of standard "test pits," with various known grades
of uranium mineralization, located at the DOE's Grand Junction, Colorado office.
The ratio of cps to known uranium grade is referred to as the probe "K-Factor",
and this value is determined for every gamma probe when it is first manufactured
and is also periodically checked throughout the operating life of each probe.
Application of the K-Factor, along with other probe correction factors, allows
for immediate grade estimation in the field as each drill hole is logged.

Core samples are collected for a number of purposes:
verification of lithology as determined from geophysical logging and examination
of drill cuttings; determination of uranium content as a general check of gamma
probing to determine if gamma measurement and chemical uranium content are close
to balance ("radiometric disequilibrium"); whole rock analysis; and specific
geochemistry for uranium species and other minerals of interest. Typically core
is only taken over select intervals of interest as identified from logging of
drill holes. This reduces the amount of core through barren zones or horizons of
no interest and greatly reduces overall exploration costs.

Core diameter is typically 21⁄2  31⁄4 inches. For zones selected
for laboratory analyses, one half of the core will normally be used. The minimum
length of core submitted is usually one foot and the maximum length per sample is two feet. Sample intervals are selected by
geologists in the field based on lithology, oxidation/reduction, and uranium
grade (from gamma logging and from hand-held gamma counters). Core samples are
prepared at White Mesa. Samples are crushed and then ground to -200 mesh. The
sample pulps are split to 250 to 300 grams for laboratory work.

Drill hole logging is conducted by Energy Fuels in-house
personnel, in general. The logging capabilities are designed specifically to
meet Energy Fuel's logging requirements in the southwest United States. The
tools, and a complete set of spares, were manufactured by Mount Sopris
Instrument Company in Golden, Colorado. EFI has retained the services of a
senior geophysical consultant to oversee training, implementation, and quality
control protocols for the southwest United States' operations. All tools are
checked and calibrated before being used, and a variety of system checks and
standards are also established for routine checking and calibration of tools.

Drill hole logging data is stored on digital media in the
logging truck at the exploration sites. The digital data is periodically brought
in from the field locations to the Egnar, Colorado field office. The raw and
converted logging data are copied and then sent via e-mail to Energy Fuel's
Denver office, where all data is checked and reviewed. Samples of core are
chosen on the basis of radiometric data collected during core logging. This
radiometric data is obtained by using a hand held scintillometer. The general
concept behind the scintillometer is similar to the gamma probe except the
radiometric pulses are displayed on a scale and the respective count rates are
recorded manually by the geologist logging the core. The hand-held
scintillometer provides quantitative data only and cannot be used to calculate
uranium grades. However, it does allow the geologist to identify uranium
mineralization in the core and to select intervals for geochemical sampling.

Additional samples are collected above and below the horizons
of interest in order to "close-off" sample intervals. Sample widths are selected
according to radiometric values and lithologic breaks or changes. All reasonable
efforts are made to ensure that splitting of the core is representative and that
no significant sampling biases occur. Once the sample intervals are identified,
an exclusive sample number is assigned each interval and recorded by the on-site
geologist.

After the geological logging of the core and sample selection,
all of the selected sample intervals of drill core are split longitudinally at
the drill site. One half of the core is placed in a new sample bag along with a
sample tag corresponding to the sample number. The other half of the core is
re-assembled in the core box and stored for future reference. Samples are stored
at the Egnar, Colorado office under the supervision of the project geologists
and delivered to either White Mesa or an analytical lab for preparation. As
standard procedure, field duplicates are included in assay suites sent to the
laboratories, and reference samples are used to verify laboratory controls and
analytical repeatability.

Mineral Resource Estimate

Energy Fuels published an Inferred Mineral Resource for the
Daneros property on July 19, 2012, soon after the property was acquired from
Denison, reporting 156,000 tons of mineralized material at an average grade of
0.263% eU3O8 for a total of 824,100 lbs. of U3O8. The current resource estimate, after taking
into account production from 2010 through October 17, 2012, is 155,724 tons at
an average grade of 0.212% eU3O8 for a total of 661,000 lbs. of U3O8.

Energy Fuels has prepared resource estimates for the Daneros
Project, located in Bullseye Canyon of southeastern Utah. This resource estimate
was prepared using both historical as well as recent data. The Daneros Mine
Technical report presents the raw data and model wireframe creation methods. The
suitability of the interpolation technique and search strategies is also
presented. Energy Fuels created a wireframe model of the mineralized zone based
on the outside bound of a 0.15% eU3O8 GT contour as well as the stratigraphic boundaries within which the known
mineralization occurs; the Shinarump Sandstone member of the Triassic Chinle
Formation. The raw data in the DAN database was composited over 2 foot
run-length intervals to generate a preliminary database necessary to create a
preliminary block model. A 0.15% eU3O8 grade-shell was created and superimposed
upon the boundaries of the GT contour and the stratigraphic surfaces to create a
wireframe model of the mineralized zone in which to place the following block
model and grade interpolation. The Energy Fuels Daneros database contains two
sets of drill holes totaling 300 drill holes, totaling 141,087 feet. Drill holes
in the DAN series have had downhole as well as collar surveys, down-hole gamma
and resistance surveys and, where available, have had their core assayed. The
second set of drill holes are named the 125 series and the LR series holes.
This last set of holes is historic in nature and their locations, as well as
their reported gamma-logged intervals are historic and the down-hole data
contained could not be verified.

83

---

The historic database was received in both paper form, as a
table, as well as in electronic form as an excel spreadsheet compiled by WCU.
Several collars of the historic holes were surveyed by Energy Fuels surveyors
and the group was adjusted in Vulcan to reflect the translation between UT-S
(NAD 27, Utah South, State Plane) and UT83-SF (NAD 83, Utah South, State Plane)
coordinate systems. After the adjustment, several holes were checked to validate
the collar locations. All surveyed collars fell within a two foot radius of the
adjusted collars and Energy Fuels considers this acceptable accuracy for placing
the collars of the second, historic set of drill holes. Energy Fuels finds the
complete database acceptable for use in the resource estimation. All drill holes
in both sets makeup the drill hole database for the inferred resources reported
herein. The database is made up of the four files; DAN_COLLARS_CLN.csv,
DAN_GRADE_CLN.csv, DAN_SURVEY_CLN.csv and DAN_STRAT_CLN.csv. EFI imported these
files into Vulcan 3D Mine Modeling software to perform the resource estimation.
The database was verified with the following checks; unique collar location,
proximity to the surveyed surface, overlapping intervals and increasing and
decreasing values (depth, from and to). All drill holes passed all validations
before the database was considered sound. The 1,251 eU3O8 values reflect gamma
readings along the length of the drill holes. The readings were taken at regular
0.5 foot intervals for the Daneros dataset. It is assumed that the 125 and
LR datasets were also logged in the same manner, however, grade was only
reported for the mineralized interval. As of 07-17-12 the operating costs for
uranium production from Daneros are approximately $300.00 per ton of ore grade
material. Energy Fuels assumes a reasonable price for their product, U3O8 at
$60.00/lb .. Therefore, 0.25% U3O8 is considered a reasonable cutoff grade.
Energy Fuels considers the base of the Shinarump Sandstone to be the lowest
horizon at which economic mineralization occurs in the Bullseye Canyon area and
therefore represents a solid boundary beyond which (above) compositing of the
Daneros database should begin. The data were composited on two foot run-length
intervals within the solid model of the Shinarump Sandstone and not beyond. In
this manner only that material within the model is considered for the resource
estimate. The GT contour provided a convenient guide showing where the most
promising mineralized intercepts were located relative to one another. There are
several population breaks present with the most significant being at the
approximately the 97th percentile corresponding to a grade of 0.8% eU3O8. Energy
Fuels considers this a reasonable capping level to avoid the adverse effects of
high grade outliers on the data population. Grades above 0.8% eU3O8 were
assigned this value and remain a part of the working dataset. Capping the raw
grade dataset at 0.8% eU3O8 set back fifty values or 4% of the individual data
in the dataset. Energy Fuels used Vulcan 3D Mine Modeling software to create the
resource estimate. A block model was created where each block was 50 ft by 50 ft
by 5 ft, with 5 ft by 5 ft by 2.5 ft subblocks. The model origin is at 2021000
ft. E, 10177000 ft. N, and 5730 ft. elevation in the Utah State Plane Coordinate
System, NAD 83, South zone. The preliminary block model is oriented at 42
degrees azimuth to reflect the direction of the suspect channel splay and
extends for 10,000 ft in the northeast direction, 10,000 ft in the northwest
direction and 400 ft in elevation. The final block model was restricted to
within the gradeshell. Average grades of the blocks. For Daneros, the respective
values are 0.15 %, 0.227 % and 0.244 %. It is recommended that further study is
done with respect to the search strategy and interpolation method.

The ore mined from the Daneros Mine has been successfully
milled at the White Mesa Mill. The milling operation involves grinding the ore
into a fine slurry and then leaching it with sulfuric acid to separate the
metals from the remaining rock. Uranium and vanadium are then recovered from
solution in separate solvent extraction processes. The uranium is precipitated
as a U3O8 concentrate, yellow cake, which is dried and sealed in 55-gallon
steel drums for transport off-site. The White Mesa Mill owned by Energy Fuels is
located six miles south of Blanding, Utah, 65 road miles from the Daneros Mine.
Its construction by Energy Fuels Nuclear Inc. was based on the anticipated
reopening of many small low-grade mines on the Colorado Plateau, and the mill
was designed to treat 2,000 tons of ore per day. The mill has operated at rates
in excess of the 2,000 tons per day design rate. Construction commenced in June
1979 and was completed in May 1980. The mill has been modified to treat higher
grade ores from the Arizona Strip, as well as the common Colorado Plateau ores.
Processing of Arizona Strip ores is typically at a lower rate of throughput than
for the Colorado Plateau ores. The basic mill process is a sulphuric acid leach
with solvent extraction recovery of uranium and vanadium. Since 1980, the mill
has operated intermittently in a series of campaigns to process ores from the
Arizona Strip as well as from a few higher grade mines of the Colorado Plateau,
and alternate feed materials during intervals when mine production is small or
nonexistent. Overall, the mill has produced approximately 30 million pounds U3O8
and 33 million pounds V2O5. Run-of-mine ore is reduced to minus 28 mesh in a
six-foot by 18-ft. diameter semiautogenous grinding (SAG)mill.
Leaching of the ore is accomplished in two stages: a pre-leach and a hot acid
leach. The first, or pre-leach, circuit, consisting of two mechanically agitated
tanks, utilizes pregnant (high-grade) strong acid solution from the
countercurrent decantation (CCD)circuit which serves both to initiate
the leaching process and to neutralize excess acid. The pre-leach circuit
discharges to a 125-ft.thickener where the underflow solids are pumped to the
second stage leach and the overflow solution is pumped to clarification,
filtration, and solvent extraction circuits. A hot strong acid leach is used in
the second stage leach unit, which consists of seven mechanically agitated tanks
having a retention time of 24 hours. Free acid is controlled at 70 grams per
litre and the temperature is maintained at 75°C. Leached pulp is washed and
thickened in the CCD circuit, which consists of eight high-capacity thickeners.
Underflow from the final thickener at 50% solids is discharged to the tailings
area. Overflow from the first thickener (pregnant solution) is returned to the
pre-leach tanks. The solvent extraction (SX) circuit consists of four extraction
stages in which uranium in pregnant solution is transferred to the organic
phase, a mixture consisting of 2.5% amine, 2.5% isodeconal, and 95% kerosene.
Loaded organic is pumped to six stages of stripping by a 1.5 molar sodium
chloride solution, and thence to a continuous ammonia precipitation circuit.
Precipitated uranium is settled, thickened, centrifuged, and dried at 1,200°F.
The final product at about 95% U3O8 is packed into 55-gallon drums for
shipment.

Mining Operations

UEC gathered the necessary environmental data and obtained the
approvals to open an underground uranium mine at Daneros. A Plan of Operations
(PO) was submitted to the BLM and approved in May 2009, following which
UEC commenced active mine development, including driving a decline into the main
Daneros deposit. The first loads of ore from the Daneros Mine were delivered to
the White Mesa Mill in December 2009, and a toll milling campaign was conducted
in the second half of 2010. The Daneros Mine is now operated by Energy Fuels,
and, prior to being placed on standby, ore from the mine was delivered to the
White Mesa Mill and processed for Energy Fuels account.

The initial mine plan at Daneros involved driving twin declines
(with the second decline for emergency escape and ventilation) into the center
of the Daneros deposit and developing away from the entry point. Random room and
pillar mining is employed, as is typical for the deposits in the local region.
Mining utilizes rubber tired loaders and small trucks to transport ore to the
surface, where it is loaded into over-the-road trucks, covered by a secure
tarpaulin and transported to the White Mesa Mill.

Permitting

The primary permits required for mining operations at Daneros
include a Mine Permit issued by UDOGM and a PO approved by the BLM. The BLM PO
required document preparation and public notice of an EA. The permits obtained
by UEC were for the initial stage of operations and contemplated eventual
expansion of the mining operations, with the inclusion of additional surface
area for support facilities. The Daneros Mine does not discharge any water, so
no discharge permit is required.

Following approval of the PO by the BLM, an appeal of the BLM
approval was filed by Uranium Watch and associated non-government organizations.
The appeal was ultimately denied by the Utah BLM State office, and appealed by
Uranium Watch (and others) to the Department of Interior Board of Land Appeals,
which denied the appeal on September 26, 2012.

Permitting for mine expansion began in 2012 with the submittal
of a construction application to the Utah Division of Air Quality
(UDAQ) and EPA for radon emissions. This application, which was
approved in 2nd Quarter 2012 requires monitoring and annual reporting
of radon emissions from the mines ventilation system. An air permit application
was submitted to UDAQ for other regulated air emissions (e.g., fugitive dust,
volatile organic compounds) in 4th Quarter 2012. In 1st
Quarter 2013, an amended PO and a Large Mine NOI were submitted to the BLM and
UDOGM, respectively. An EA is currently being conducted for the proposed mine
expansion.

Current and Contemplated Exploration and Development
Activities

Energy Fuels has no current exploration plans at the Daneros
Mine. The mine is fully permitted and developed. The Company is maintaining the
project on care and maintenance. Additional permitting is ongoing as described
above.

The Sheep Mountain Project

Unless otherwise stated, the following description of the Sheep
Mountain Project is derived from a technical report entitled Sheep Mountain
Uranium Project, Fremont County, Wyoming, USA, Updated Preliminary Feasibility
Study, National Instrument 43-101 Technical Report, dated April 13, 2012 and,
prepared by Douglas L. Beahm, P.E., P.G., Principal Engineer of BRS Engineering
in accordance with NI 43-101 (the Sheep Mountain Technical Report, also
referred to herein as the 2012 PFS). The author of the Sheep Mountain
Technical Report is a qualified person and is independent of the Company
within the meaning of NI 43-101. The Sheep Mountain Technical Report is
available on SEDAR at www.sedar.com.

Overview

The Sheep Mountain Project was acquired on February 29, 2012,
as a result of the merger transaction between Energy Fuels and Titan. Titan
acquired the Sheep Mountain Project in two transactions in 2009. A 50% working
interest was acquired when Titan completed a business combination with Uranium
Power Corp. (UPC) on July 31, 2009. UPC is now a wholly-owned
subsidiary of Energy Fuels. At that time, UPC and UPCs US subsidiary (then
called UPC Uranium (USA) Inc. and now called Energy Fuels Wyoming Inc.) became
wholly-owned subsidiaries of Titan. The remaining 50% was owned by Uranium One
Inc. which was UPCs joint venture partner for the property. On October 1, 2009,
Titan acquired Uranium One Inc.s 50% interest in the property, giving Titan a
100% interest. On February 29, 2012, Energy Fuels acquired Titan (and its
subsidiaries) at which point the Sheep Mountain Project became 100% owned by the
Company. See General Development of the Business  Significant Acquisitions
 Acquisition of Titan Uranium Inc. above.



Project Description and Location

The Sheep Mountain Project is located eight miles south of
Jeffrey City, Wyoming within the Wyoming Basin physiographic province at the
northern edge of the Great Divide Basin in central Wyoming. The project is
located in portions of Sections 8, 9, 15, 16, 17, 20, 21, 22, 27, 28, 29, 30,
31, 32, and 33, Township 28 North, Range 92 West. The mineral properties are
comprised of 192 unpatented mining claims (the Company added 13 claims to the
179 reported in the Technical Report) on land administered by the BLM,
approximately 640 acres of State of Wyoming leases and approximately 630 acres
of private lease lands. In February 2012, Energy Fuels purchased 320 acres of
private surface overlaying some of the Federal minerals covered by 18 of the
claims. The combination of land holdings (including the 13 new claims) comprises approximately 4,675 acres and gives
Energy Fuels mineral rights to resources as defined in the Congo Pit and the
Sheep Underground mine areas.

87

---

To maintain these mineral rights, The Company must comply with
the state lease provisions including annual payments with respect to the State
of Wyoming leases; private leases; BLM and Fremont County, as well as Wyoming
filing and/or annual payment requirements to maintain the validity of the
unpatented mining lode claims as follows. Mining claims are subject to annual
filing requirements and payment of a fee of $140.00 per claim or an aggregate
annual cost of $25,060.00 for the unpatented mining claims currently held.
Unpatented mining claims expire annually, but are subject to indefinite annual
renewal by filing appropriate documents and paying the fees described above. ML
0-15536 will expire on 1/1/2024. Annual Payments to maintain ML 0-15536 are
$2,560 per year. Private lease will expire 11/20/2015 (and for as long as
minerals are being produced). The private lease may be extended for an
additional ten year term by the Company making a delay rental payment of
$10,000. Properties covered by Private Lease include: Township 28 North, Range
92 West, 6th PM; Section 20: S1⁄2SW1⁄4; Section 29: NW1⁄4, SW1⁄4SW1⁄4; Section 30: SE1⁄4NE1⁄4,
E1⁄2SE1⁄4; Section 31: E1⁄2NE1⁄4; Section 32: E1⁄2NE1⁄4; Section 33: S1⁄2NW1⁄4. Payments $10,000
per year as annual delay rentals. Per examination of original private lease
dated 11/20/1975 between McIntosh Cattle Company and Western Nuclear Inc.

The project is subject to an overall sliding scale royalty of
1% to 4% due to Western Nuclear, based on the Nuclear Exchange Corporation
Exchange Value. This royalty is currently at its maximum rate of 4%. A Royalty
under a private lease is due to McIntosh (to Ellen Fox and Jennifer McIntosh, as
heirs) of 7.5% of the mined value of uranium ores in raw, crude form (which
equals 50% of the average sales price of uranium concentrate made during the
previous month). According to a Surface Owners Agreement, to William and
Jennifer McIntosh, 1% of the proceeds received from the sale of all uranium
mined, shipped and sold from claims under the surface owned by the grantors. Per
the Surface Owners Agreement dated 1/27/1970 between Bessie McIntosh, Phyllis
DeWalt, William McIntosh, and John McIntosh (grantors) and Western Nuclear Inc.
(grantee), amended on 4/14/1981 by Amendment of Surface Owners Agreement
between William and Jennifer McIntosh (as successors to grantors above) and
Western Nuclear Inc. and ratified by Ratification of Surface Owner's Agreement"
on 4/16/2007 by Ellen Fox (as heir of William McIntosh) and US Energy (as
successor to Western Nuclear). Under Wyoming state lease ML 0-15536, there is a
royalty of 5% of the quantity or gross realization value of the U3O8, based on
the total arms-length consideration received for uranium products sold for
shipping point.

Additional information regarding land tenure is described in
the Sheep Mountain technical Report.

A Plan of Operation (PO) was submitted and has been accepted
as complete by the U.S. Bureau of Land Management (BLM), and preparation of an
Environmental Impact Statement (EIS) is underway with completion anticipated
for mid-2013. The Company has submitted a revision of its existing Mine Permit
381C to the Wyoming Department of Environmental Quality (WDEQ). The permit
revision will address improvements to the mine plan, including the proposed
uranium recovery facility. Development of an application to the NRC for a
combined Source Material and By-product Material License to construct and
operate the uranium recovery facility is at an advanced stage of development.
This license will allow the Company to process the uranium ore and produce
yellowcake at the Sheep Mountain Project site. Due to various delays and
planning evaluations, the Company now plans to submit the license application in
mid-2014 unless other processing options become better choices. The subsequent
review and approval process for this license by NRC is anticipated to take
approximately 24 months.

The Company is subject to liabilities for mine and exploration
reclamation at the Sheep Mountain Project. The Company maintains four (4) bonds
with the State of Wyoming as security for these liabilities. The Company files
annual reports with the State of Wyoming, and the amount of the bonds may be
adjusted annually to endure sufficient surety is in place to cover the
full cost of reclamation. Uranium mining in Wyoming is subject to both a gross
products (county) and mineral severance tax (state). At the federal level:
aggregate corporate profit from mining ventures is taxable at corporate income
tax rates, i.e. individual mining projects are not assessed federal income tax
but rather the corporate entity is assessed as a whole. For mineral properties:
depletion tax credits are available on a cost or percentage basis whichever is
greater. The percentage depletion tax credit for uranium is 22%, among the
highest for mineral commodities, IRS Pub. 535.

Accessibility, Climate, Local Resources, Infrastructure, and
Physiology

The Sheep Mountain Project is located at approximate Latitude
42°24 North and Longitude 107° 49 West, within the Wyoming Basin physiographic
province in the Great Divide Basin at the northern edge of the Great Divide
Basin. The project is approximately eight miles south of Jeffrey City, Wyoming.
The nearest commercial airport is located in Riverton, Wyoming approximately 56
miles from Jeffrey City on a paved two-lane state highway. The project is
accessible via 2-wheel drive on existing county and two-track roads.

The Sheep Mountain Project falls within the intermountain
semi-desert weather province, with average maximum temperatures ranging from
31.1 °F (January and December) to 84.9 °F (July), average minimum temperatures
ranging from 9.1 °F (January) to 49.2 °F (July), and average total precipitation
ranging from 0.36 -inches (January) to 2.04 -inches (May). The Company has
established an on-site remote weather station and has recorded temperature,
precipitation (rain and snow), barometric pressure, and wind speed since 2010.
The topography consists of rounded hills with moderate to steep slopes.
Elevations range from 6,600 feet to 8,000 feet above sea level. The ground is
sparsely vegetated with sage and grasses and occasional small to medium sized
pine trees at higher elevations. Year-round operations are contemplated for the
Sheep Mountain Project.

Telephone, electric and natural gas service adequate for the
planned mine and mineral processing operations have been established at the
Sheep Mountain Project. Electric service and a waterline have been extended via
right-of-way issued by the BLM in 2011 to both the Sheep 1 and 2 shafts.
Adequate water rights are held by the Company for planned mining and mineral
processing operations but need to be updated with the Wyoming State Engineer
with respect to type of industrial use, points of diversion, and points of use.

The Company believes that sufficient surface rights are in
place for all contemplated mining operations including tailings storage areas,
waste disposal, heap leach pads, and potential processing sites.

History

Uranium was first discovered in the Crooks Gap district, which
includes the Sheep Mountain Project, in 1953 (Bendix, 1982). While the original
discoveries were aided by aerial and ground radiometric surveys, exploration
activities were primarily related to drilling and exploratory trenching. Three
companies dominated the district by the mid-1950s: Western Nuclear Inc.
(Western Nuclear), Phelps Dodge Corporation (Phelps Dodge),
and Continental Uranium Corporation (Continental). Western Nuclear
built the Split Rock mill at Jeffrey City in 1957 and initiated production from
the Paydirt pit in 1961, Golden Goose 1 in 1966, and Golden Goose 2 in 1970.
Phelps Dodge was the principal shareholder and operator of the Green Mountain
Uranium Corporations Ravine Mine which began production in 1956. Continental
developed the Seismic Pit in 1956, the Seismic Mine in 1957, and Reserve Mine in
1961 and the Congo Decline in 1968. In 1967, Continental acquired the Phelps
Dodge properties and in 1972, Western Nuclear acquired all of Continentals
Crooks Gap holdings. During the mid-1970s Phelps Dodge acquired an interest in
Western Nuclear which began work on the Sheep Mountain I in 1974, the McIntosh Pit in 1975, and Sheep
Mountain II in 1976. Western Nuclear ceased production from the area in 1982.
Western Nuclear production from the Sheep Mountain I is reported to have been
312,701 tons at 0.107%U3O8.Subsequent to the
closure of the Sheep Mountain I by Western Nuclear, during April to September
1987, Pathfinder Mines Corporation (Pathfinder) mined a reported 12,959
tons, containing 39,898 lbs. of uranium at an average grade of 0.154%
U3O8 from Sheep Mountain I. U.S. Energy-Crested
Corp. (USECC) acquired the properties from Western Nuclear in 1988 and
during May to October 1988, USECC mined 23,000 tons from Sheep Mountain I,
recovering 100,000 lbs. of uranium for a mill head grade of 0.216% U3O8. The
material was treated at Pathfinders Shirley Basin mill, 130 miles east of the
mine. The Sheep Mountain I mine was allowed to flood in April 2007. In December
2004, UPC (then known as Bell Coast Capital) acquired a 50% interest in the
property from USECC in late 2007. USECC later sold all of its uranium assets to
Uranium One Inc. Titan acquired UPCs 50% interest in the property when it
acquired UPC by a plan of arrangement in July 2009. Titan acquired Uranium One
Inc.s interest in the Sheep Mountain Project in September 2009.

Geological Setting

A primary component of the geology for the Sheep Mountain
Project is the Battle Spring Formation. Battle Spring is Eocene in age. Prior to
deposition of the Battle Spring Formation and subsequent younger Tertiary
formations, underlying Paleocene, Cretaceous, and older formations were deformed
during the Laramide Orogeny. During the Laramide Orogeny, faults, including the
Emigrant Thrust Fault at the northern end of the project area, were active and
displaced sediments by over 20,000 feet. Coincident with this mountain building
event, Paleocene and older formations were folded in a series of echelon
anticlines and synclines, generally trending from southeast to northwest. The
Battle Spring Formation was deposited unconformably on an erosional landscape
influenced by these pre-depositional features. Initial stream channels
transporting clastic sediments from the Granite Mountains formed in the
synclinal valleys. The geologic setting of the Sheep Mountain Project is
important in that it controlled uranium mineralization by focusing movement of
the groundwaters which emplaced the uranium into the stream channels which had
developed on the pre-tertiary landscape. The Battle Spring Formation and
associated mineralization at Sheep Mountain is bounded to the east by the
western flank of the Sheep Mountain Syncline and to the west by the Spring Creek
Anticline. To the north the system is cut off by erosion. To the south the
Battle Spring continues into the northern portions of the Great Divide Basin.
Mineralization occurs throughout the lower A Member of the Battle Spring
Formation and is locally up to 1,500 feet thick. The upper B Member is present
only in portions of the project and may be up to 500 feet thick. Although
arkosic sandstone is the preferred host, uranium has been extracted from all
lithologies. Grade and thickness are extremely variable depending on whether the
samples are taken from the nose or the tails of a roll front. Typically the
deposits range from 50 feet to 200 feet along a strike, five feet to eight feet
in height, and 20 feet to 100 feet in width. Deposits in the Sheep Mountain area
occur in stacked horizons from 7,127 feet in elevation down to 6,050 feet in
elevation.

Exploration

During the National Uranium Resource Evaluation (NURE)
program conducted by the DOE in the late 1970s and early 1980s, the project
area and vicinity were evaluated. This evaluation included aerial gamma,
magnetic, and gravimetric surveys, soil and surface water geochemical surveys
and sampling, and geologic studies and classification of environments favorable
for uranium mineralization. Additional information on exploration is included in
the Drillingsubsection below.

Mineralization

Most of the mineralization in the Crooks Gap district occurs in
roll-front deposits. Roll fronts have an erratic linear distribution but are
usually concordant with the bedding. Deposits have been discovered from the surface down to a depth of 1,500 feet. The two major
uranium minerals are uranophane and autunite. Exploration drilling indicated
that the deeper roll-type deposits are concentrated in synclinal troughs in the
lower Battle Spring Formation. Three possible sources for uranium have been
suggested: post-Eocene tuffaceous sediments, leached Battle Spring arkoses, and
Precambrian granites. Structural controls of uranium occurrences along roll
fronts include carbonaceous siltstone beds that provide a local reducing
environment for precipitation of uranium-bearing minerals, and abrupt changes in
permeability along faults, where impermeable gouge is in contact with permeable
sandstones.

Drilling

Approximately 4,000 holes were drilled in the project area
historically (prior to 1988), most of which were open-hole rotary drilling,
reliant upon down-hole geophysical logging to determine %eU3O8. However, some
core drilling for chemical analysis was also completed. The drill maps show hole
locations at the surface and downhole drift, the thickness and radiometric grade
of uranium measured in weight percent U3O8, elevation to the bottom of the
mineralized intercept, collar elevation, and elevation of the bottom of the
hole.

In 2005, UPC completed a drilling program consisting of 19
holes totaling 12,072 feet. Two of the 19 holes were located in Section 28 with
the purpose of confirming the mineralization within the Sheep Underground mine
area. The remaining 17 holes were completed in the planned Congo Pit to test
both shallow mineralization and to explore a deeper mineralized horizon. This
2005 drilling has confirmed the presence of mineralization in the shallow
horizons of the Congo Pit area and has identified and extended roll front
mineralization in the 58 sand along strike.

Following the acquisition of UPC by Titan, five holes were
drilled in the Congo Pit area in 2009 for a total of 1,700 feet. These were
completed by rotary air drilling to depths exceeding 300 feet using a top drive
rotary drilling rig. The drill cuttings were collected continuously during the
drilling process, in two foot increments. Over 500 pounds of mineralized
material was collected for metallurgical testing. In situ mineral grades for
2009 drilling were determined by geophysical logging including both conventional
gamma logging and state of the art Uranium Spectrum Analysis Tool. Titan, now
known as Energy Fuels Wyoming Inc. also drilled in the Congo Pit area in 2010
and 2011. There were a total of 142 holes drilled between 2009 and 2011, which
total about 44,000 feet.

The Congo mineralized thickness ranges from one foot to over 19
feet. Grade varies from the minimum grade cutoff of 0.1% eU3O8to a maximum
reported grade of 1.87% eU3O8.

The Sheep Underground data set is composed of a total of 485
drill holes based on data from 483 historic drill holes and two confirmatory
drill holes completed in 2005. Of the 485 drill holes, only 33 were barren and
452 contained mineralization of at least 0.5 -feet of 0.05% eU3O8. Sheep
Underground mineralized thickness ranges from 0.5 feet to over 26.5 feet. Grade
varies from the minimum grade cutoff of 0.05% eU3O8to a maximum reported grade of
2.19% eU3O8.

Estimated trend width and length were based on the geologic
model and actual mine workings as follows. The Sheep typical trend width is
approximately 100 ft. The mine maps available for the Sheep area show
development drifts, ready for extraction, with widths greater than 100 ft. In
the limited areas where full extraction occurred, mined out rooms were 50 to 100
feet or in some cases wider. The Sheep trend length varies from a few hundred
feet to a maximum length of about 5,500 feet based on correlation of geophysical
logs.

Sampling and Analysis

The majority of the sample data available for the evaluation of
resources for the Sheep Mountain Project is the historic geophysical log data.
Titan has the complete hard copy data set which was passed through the chain of
property title from Western Nuclear Corporation; through US Energy Crested
Corporation (USECC); through the joint venture between UPC and U1; to
Titan through its acquisition of UPC and acquisition of U1s share of the
property; and ultimately to Energy Fuels, though its acquisition of Titan. For
the Congo Pit, Sheep Underground, and Sun Mc areas, the majority of the hard
copy logs were reviewed both for data verification and for geologic
interpretation. The majority of the Sheep Underground logs were also available
as scanned images. In addition, the data includes an extensive collection of
detailed mine and drill maps, both surface and underground. The underground maps
show the extent of mining by date and include rib and longhole data. All
pertinent maps with respect to mine design, extent of mining, drill maps, and
mapping related to the mine permit have been scanned and rectified digitally.
This data is stored at BRS Riverton, Wyoming office Mineral resource and
reserve estimates for the Sheep Mountain Project are based on radiometric data.
As discussed in Sections 14 and 24 of the Sheep Mountain Technical Report,
available data indicates that variations in radiometric equlibrium are local in
their effect which impacts the mining grade control program but does not
appreciably affect the overall mineral resources or reserves. Confirmatory
drilling in accordance with NI 43-101 began in 2005. The author did not observe
this drilling but has reviewed the geologic and geophysical log data and finds
the data to have been collected in accordance with current industry practice and
to be reliable. This data confirms historical drilling results and is current
and applicable to this Preliminary Feasibility Study.

With respect to the 2009 drilling program completed by Titan,
drilling and sampling was observed by and/or completed by Titan and BRS
personnel, including the author and employees under his direct supervision.
Drill samples were collected not for verification of radiometric assay but for
overburden testing per WDEQ regulations and for metallurgical testing. Drill
samples for overburden testing were split with a standard rifling splitter with
half of the sample sent to Energy Laboratories Inc. of Casper, Wyoming, an
independent certified commercial analytical laboratory, for testing in
accordance with WDEQ guidelines and the remainder was sealed in plastic bags and
is currently stored in an on-site warehouse facility. Drill samples for
metallurgical testing were stored and sealed in new 5 gallon plastic buckets.
Samples within the mineralized zones as determined by gamma and USAT logging
were delivered to Lynteks facility in Denver, Colorado for further assay and
testing by BRS personnel. A chain of custody was established. Representative
sample splits were prepared for chemical assay and were delivered to Energy
Laboratories Inc. of Casper, Wyoming, an independent certified commercial
analytical laboratory, for assay utilizing standard protocol and adhering to a
chain of custody. These assays were used in the selection of samples for
metallurgical testing. In addition to the samples from the Congo Pit drilling,
mineralized stockpiles from mine material at the Sheep I shaft was sampled,
assayed, and utilized for metallurgical testing. Seven samples of the Sheep I
stockpile were collected ranging in grade from 0.022 to 0.067 %U3O8 and
averaging 0.045 % U3O8. Bottle roll leach tests have been completed for
composite samples selected to represent mineralization at both the Congo Pit and
Sheep Underground. The remaining samples, with the exception of reserves sample
splits, were utilized in the column leach testing for heap leach amenability.
Assays of blind duplicates of select samples and check assays, at Hazen
Research, a separate and independent commercial laboratory were completed. The
results of the assays compared favorably. The assay data was generally not used
to verify the radiometric data as this had already been done using the USAT
data. A general comparison of assay data to USAT data was completed and the
results were comparable. Radiometric equilibrium determinations are discussed in
Section 24. No samples were collected during the 2010 drilling program. Drill
cuttings were logged in the field. All holes were logged by a commercial
geophysical logging company. Geophysical log data was provided in both hard copy
and electronic format with the down-hole count data converted to 1⁄2 foot
equivalent %U3O8 grades. In 2011 both rotary and reverse circulation drilling
was completed. Bulksamples from the reverse circulation drilling have been
retained in sealed containers stored at the site for further metallurgical
testing but no chemical assays have been completed as of the effective date of
the Sheep Mountain Technical Report. The reader should note that it is common
industry practice for the exploration and evaluation of uranium mineralization
in the US to rely upon downhole geophysical log data for the determination of
the thickness and grade of mineralization. The sampling and assay methods
described herein were for the purposes of developing bulk composite samples for
metallurgical testing and environmental testing. Downhole geophysical log data
was converted to equivalent uranium assays in half foot increments for
geophysical logs with digital data. Geophysical logs with only analog data were
interpreted using standard methods set out originally by the AEC. The primary
method employed for this project is referred to as the half amplitude method. In
the case of the half amplitude method the sample thickness is determined by the
log signature and while interpreted to the nearest half foot the thickness of
the sample varies. The author of the Sheep Mountain Technical Report was trained
in this methodology through a short course conducted by Century Geophysical
Corporation of Tulsa, Oklahoma and has extensive experience in the
interpretation of geophysical logs.

Mineral Resource and Mineral Reserve Estimates

The mineral resource estimation geological interpretation
methods methodology described herein have been employed by the author while
working at similar operating uranium mines in the Gas Hills. The mining methods
and factors recommended have been employed successfully at the project in the
past. Successful uranium recovery from the mineralized material at Sheep
Mountain and similar areas such as the Gas Hills has been demonstrated via both
conventional milling and heap leach recovery. The project is a brown-field
development located in a state which tends to favor mining and industrial
development. The project has been well received locally and will also provide
substantial revenues to both Fremont County and the State of Wyoming in addition
to providing long term employment for the region. The author was not aware of
any factors including environmental, permitting, taxation, socio-economic,
marketing, political, or other factors which would materially affect the mineral
resource estimate, herein. The estimate of mineral resources for the Sheep
Underground and the Sun Mc area are unchanged from the previous reports (BRS,
2011). With respect to the open pit area: mineral resources for the Congo, North
Gap and South Congo areas were combined into a single comprehensive mineral
resource model. Additional areas of mineralization, based on historical data,
are known within the project area but have not been included in the mineral
resource estimate at this time.

The mineral resource estimates presented herein have been
completed in accordance with CIM Standards and NI 43-101. Based on the drill
density, the apparent continuity of the mineralization along trends, geologic
correlation and modeling of the deposit, a review of historic mining with
respect to current resource projections, and verification drilling, the Mineral
Resource estimate herein meets CIM criteria as an Indicated Mineral Resource.

This estimate includes deletion of the portions of the mineral
resource model which falls within the historic mine limits which equated to
approximately 25% of the initial resource estimate. Historic mining limits were
imported into the resource model by individual sand horizons in three
dimensions. The extent of mining was taken to be the actual mapped underground
mine limit or the GT boundary representing the historical mining cutoff (8 feet
@ 0.095 or a GT of 0.76), whichever was greatest. Although in many cases the
mine maps showed remnant pillars, none of these areas were included in the
mineral resource estimate. Thus, the estimate of current mineral resources is
conservative with respect to the exclusion of areas affected by historic mining.
Estimated mineral resources for potential open pit areas were diluted to a
minimum mining thickness of two feet.

Geologic interpretation of the mineralized host sands was used,
along with the intercepts that met the minimum cutoff grade and thickness, to
develop a geologic model in which to estimate the mineral resources at the Sheep
Mountain Project. The three-dimensional locations along the drill hole drift of
all mineralized intercepts were plotted in AutoCAD TM. Each intercept was
evaluated based on its geophysical log expression and location relative to
adjacent intercepts. Whenever possible, geophysical logs were used to correlate
and project intercepts between drill holes. Intercepts that met the minimum
grade cutoff but were isolated above or below the host sand horizons; where data
sets were incomplete; which did not fully penetrate the host sand were excluded
from the mineralized envelope. The mineralized envelope was created by using the
top and bottom of each intercept that was within the geologic host sands. The
intercepts that were used to make this envelope were then used in the resource
estimate GT method. Drill spacing within the Project is not uniform due in part
to the steep and irregular surface terrain and in part to the somewhat random
drift or deviation of the drill holes from vertical. Drill spacing in the Congo
(open pit areas) range from roughly 50 foot centers to greater than 100 foot
centers. Drill spacing at Sheep Underground area varies from roughly 200 foot
centers to over 400 foot centers. Drilling depths at Congo are typically less
than 400 feet in the northern portions of the area to generally over 600 feet to
the south. Drilling depths at Sheep exceed 1,000 feet but are typically less
than 1,500 feet. Drilling depths at Sun Mc are variable depending on terrain but
are typically less than 1,000 feet. In development of the initial geologic
envelope, both surface drill data and data from underground mine maps was
reviewed. For the Sheep Underground and other underground mines, such as the
Seismic and Reserve mines adjacent and partially within the limits of the
planned Congo Pit, the underground development and cross cut drifts were
typically on 100 foot centers. Mining within the development drifts and cross
cuts was completed by random room and pillar methods, extracting the mineralized
material meeting the mine cutoff applicable at the time and leaving the lower
grade material as pillars. In most cases entire 100x100 foot or larger blocks
were mined and/or, in the case of the Sheep Underground, delineated by face
sampling and longhole drilling but not yet mined. The current geologic and
resource model is a 3D model based on geologic interpretation of 18 mineralized
zones in the Congo area and 17 mineralized zones in the Sheep area. Mineralized
zones from Sheep were projectable down dip to the Sun Mc Area. The estimate of
mineral resources and/or mineral reserves for the Sheep Underground Sun Mc area
in unchanged from the previous Technical Report (BRS, 2011). For the Sheep
Mountain Technical Report, the North Gap, South Congo, and Congo mineralized
zones as reported by BRS, 2011 were combined into a single unified mineral
resource model. Based on the former, once the data were separated by zone an
initial area of influence of 50 feet (maximum 25 foot radius or 50 foot
diameter) was applied to each drill hole by zone at its drifted location to
establish an initial geologic limit to the projection of mineralization.
Refinement of the geologic limit and projection of mineralization along trend
was then based on specific correlation and interpretation of geophysical logs on
a hole by hole basis. This interpretation was completed BRS staff and personally
reviewed by the author of this technical report. The mineral resource estimate
was completed using the GT (Grade x Thickness) Contour Method on individual
mineralized zones as defined in a full 3D geological model of the deposit. The
Contour Method, also known as the Grade x Thickness (GT) method, is a
well-established approach for estimating uranium resources and has been in use
since the 1950s in the US. The technique is most useful in estimating tonnage
and average grade of relatively planar bodies where lateral extent of the
mineralized body is much greater than its thickness, as was observed in drilling
of the Congo and Sheep deposits. For tabular and roll front style deposits the
GT method provides a clear illustration of the distribution of the thickness and
average grade of uranium mineralization. The GT method is particularly
applicable to the Congo and Sheep deposits as it can be effective in reducing
the undue influence of high-grade or thick intersections as well as the effects
of widely spaced, irregularly spaced, or clustered drill holes, all of which
occur to some degree in the Congo and Sheep deposits. This method also makes it
possible for the geologist to fit the contour pattern to the geologic
interpretation of the deposit. The GT contour method is used as common practice
for Mineral Reserve and Mineral Resource estimates for similar sandstone-hosted
uranium projects (Estimation of Mineral Resources and Mineral Reserves,
adopted by CIM November 23, 2003, p 51.). It is the opinion of the author that
the GT contour method, when properly constrained by geologic interpretation,
provides an accurate estimation of contained pounds of uranium. The uranium
quantities and grades are reported as equivalent U3O8 (eU3O8), as measured by
downhole gamma logging. The industry standard protocol for reporting uranium in
sandstone hosted deposits in the US has been validated for the Sheep Mountain
Project by test drilling at the deposit, as well as by correlation with previous
mining activities.

In the fall of 2009, five rotary percussion holes were drilled
on the property to study disequilibrium. Downhole logging of the drill holes was
completed using standard gamma technology as well as a Uranium Spectral Analysis
Tool (USAT), both supplied by Century Wireline of Tulsa OK. The USAT tool gives
a direct measurement of uranium content and therefore allows determination of
the equilibrium state of the uranium mineralization intersected in the hole. A
total of 34 intervals were measured, showing an overall moderate positive
disequilibrium (thus the true chemical grade of the mineralization is slightly
higher than the equivalent grade determined by the gamma tool). The results of
the resource estimates were not adjusted to account for this positive
disequilibrium. Equilibrium data does show some local distribution of uranium
values within mineralized zones. The ore control program recommended for this
project, as described in Section 16 of the Sheep Mountain Technical Report, will
account for such variations.

The estimate of mineral reserve for the Sheep Underground is
unchanged from the previous reports (BRS, 2010 and 2011). With respect to the
open pit mineral reserves, mineral resources for the Congo, North Gap, and South
Congo areas were combined into a single comprehensive mineral resource model.
Open pit mine designs and sequencing was completed for all areas, and the
resultant mineral reserve estimate reflects the current open pit mine designs
and economic evaluations.

Below is a summary of the total Probable Mineral Reserve
estimate for the Sheep Mountain Project:

GT
      minimum

    18,365,00
    7,453,000
    0.123


The Probable Mineral Reserves are fully included in the total
Indicated Mineral Resources for the Congo Pit and are not additive to that
total. The Probable Mineral Reserve is that portion of the Indicated Mineral
Resource that is economic under current cost and pricing conditions. This
estimate includes deletion of the portions of the mineral resource model which
falls within the historic mine limits. Historic mining limits were imported into
the resource model by individual sand horizons in three dimensions. The extent
of mining was taken to be the actual mapped underground mine limit or the GT
boundary representing the historical mining cutoff (7 feet @ 0.10 or a GT of
0.7), whichever was greatest. Although in many cases the mine maps showed
remnant pillars, none of these areas were included in the mineral reserve
estimate. Both the estimated mineral resources and mineral reserves were diluted
to a minimum mining thickness of two feet. The reported Probable Mineral Reserve
is that portion of the reported Indicated Mineral Resource that is within the
current open pit design. The cutoff grade of 0.05% eU3O8 at a minimum mining
height of 2 foot equates to a 0.10 GT cutoff. The following table summarizes the
portion of the Congo Pit that is economically mineable and meets the open pit
cutoff criteria.

As the operating cost per ton varies substantially between the
open pit and underground it is appropriate to have separate grade cutoff
criteria for the two operations. The following table provides a calculation of
breakeven cutoff grades for both the open pit and underground mines based on
current cost forecasts and a sales price of $65 per pound. The costs per ton
reflect operating costs only and do not include capital write off. The
calculation of breakeven cutoff grade allows for a constant tail or loss in the
mineral processing of 0.01 %U3O8. Note that staff and support costs are included
in the open pit mining costs. Incremental underground mining costs are solely
related to underground mining and mineral processing costs.

From this evaluation, and other factors such as minimum mining
thickness, the mine design cutoffs were set above the minimum breakeven cutoff
grades at:

- Open Pit

- Minimum 2 foot thickness
- Minimum grade .05 %U3O8
- Minimum GT 0.10

- Underground

- Minimum 6 foot thickness
- Minimum grade .075 %U3O8
- Minimum GT 0.45

96

---

Based on these parameters, the average grade mined from a
combined open pit and underground operation is estimated at 0.123 e%U3O8. As
mining proceeds, mineralized material encountered below the mine GT cutoff,
which has to be excavated as part of the mine plan and would otherwise be
disposed of as mine waste, could be salvaged at grades as low as the calculated
breakeven grades of 0.024 %U3O8 and 0.046 %U3O8 for the open pit and underground
mines, respectively. Without an increase in sales price or a decrease in
operating costs, material salvaged at lesser grade would not be profitable. The
mineral reserve as stated herein does not include the potential mineralized
material, which may be salvaged, which meets the breakeven grade cutoff but is
less than the design GT cutoff.

Mining Operations

The Sheep Mountain Project was operated as an underground and
open pit mine at various times in the 1970s and 1980s. 5,063,813 tons of ore
was mined and milled, yielding 17,385,116 pounds of uranium at an average grade
of 0.17%U3O8. Mining was suspended in 1988 and
the mine has been on care and maintenance since that time.

Feasibility and Resource Studies

On March 1, 2012, Energy Fuels announced the results of the
2012 PFS for the Sheep Mountain Project which updated a previous prefeasibility
study on the property prepared in 2010. The 2012 PFS increased the Probable
Mineral Reserve to 18.4 million lbs. U3O8 (7.5 million tons at an average grade
of 0.123% eU3O8). Total Indicated Resource is 12.9 million tons containing 30.3
million lbs. U3O8 at an average grade of 0.117% eU3O8, which includes the
Probable Mineral Reserve of 18.4 million lbs. U3O8(7.5 million tons at an
average grade of 0.123%eU3O8). Under the 2012 PFS, the base plan design provides
for concurrent development of both the underground and open pit deposits. The
base plan generates an expected pre-tax Internal Rate of Return (IRR)
of 42%, with an expected pre-tax Net Present Value (NPV) of $201
million at a 7% discount rate, and an expected pre-tax NPV of $146 million at a
10% discount rate. Initial Capital Expenditures (CAPEX) are expected to
be $109 million.

The Company is considering a modified plan which would be
expected to require a much reduced initial CAPEX of $61 million. The modified
plan initially develops the open pit only, and delays producing the underground
deposit until the 5th year of operations. The modified plan would be expected to
generate a pre-tax IRR of 35%, with pre-tax NPVs of $174 million at a 7%
discount rate and $118 million at a 10% discount rate.

Highlights of the 2012 PFS base plan include:

- 2012 PFS estimates are based on estimated capital and operating costs for
  a uranium mine, utilizing both conventional open pit and underground mining
  methods and heap leach recovery, with a maximum annual capacity of 1.5 million
  lbs. of U3O8;
- The financial model is based on a long-term uranium price of $65.00/lb.
  based on historical average prices over the three years prior to the date of
  the 2012 PFS, and supported by published reports of securities analysts at the
  time;
- Updated Probable Mineral Reserve of 7,453,000 tons at an average grade of
  0.123% eU3O8, containing 18,365,000 lbs. of
  U3O8, compared to the originally reported (April 12,
  2010) 6,393,000 tons at an average grade of 0.111%
  eU3O8, containing 14,186,000 lbs. of
  U3O8, an increase of 29.6% in Probable Mineral Reserve
  over the 2010 prefeasibility study;
- Initial mine life: 15 years, compared to the originally reported 11 years;
- Open pit stripping ratio: 8.1 bank cubic yards per pound mined;

- Estimated capital cost: $109 million including allowances for contingency
  and risk, compared to the originally reported $118 million;
- Estimated operating cost: $32.31 per lb. recovered, as compared to the
  originally reported $28.67 per lb. recovered;
- Estimated pre-tax NPV at a 7% discount rate: $201 million, as compared to
  the originally reported $101 million; and
- Estimated pre-tax IRR: 42%, as compared to the originally reported 25%.
- Estimated pre-tax payback period: 3 years, at a discount rate of 5%, as
  compared to the originally reported 5 years at the same discount rate.

Pre-tax NPV and IRR sensitivities are as follows:

In summary, the primary changes in the 2012 PFS that improve
economics as compared to the previous 2010 prefeasibility study:

- Use of a $65/lb. selling price rather than the $60/lb. price used
  originally;
- Open pit pounds nearly doubled, based on the increased Probable Mineral
  Reserve;
- Mine life was extended by 4 years with the expanded Probable Mineral
  Reserve; and
- Average grade for the project increased from 0.111% eU3O8to 0.123% eU3O8.

The 2012 PFS was prepared by a group of consultants led by BRS
Inc., an independent engineering consulting firm based in Riverton, Wyoming, in
collaboration with Western States Mining Consultants and Lyntek Inc. This group
also prepared the 2010 prefeasibility study. The 2012 PFS was filed on SEDAR on
April 13, 2012.

Permitting

In June 2010, Titan commenced baseline environmental studies to
support an application to the NRC for a Source Material and By-product Material
License. Work was also initiated on a revision to the existing WDEQ Mine Permit
as well as a Plan of Operations (PO) for the BLM. Baseline studies
included wildlife and vegetation surveys, air quality and meteorological
monitoring, ground and surface water monitoring, radiological monitoring, and
cultural resource surveys.

Submission of the PO to the BLM was made in June 2011. The PO
was accepted as complete by the BLM, and an EIS was initiated in August 2011.
Energy Fuels revised the PO in July 2012, consistent with the modified plan
presented in the 2012 PFS. In July 2013, the PO was again revised to reflect a
new waste rock disposal layout for the open pit mine and an improved and more
economical heap leach and processing facility. The revised PO also included the
option of transporting ore off-site for processing. Work on the EIS is ongoing
with a draft EIS scheduled to be released for public comment in 2014.

In October 2011, Titan submitted a draft revision to its
existing Mine Permit 381C to WDEQ. WDEQ then provided Titan with review comments
as part of its courtesy review. The permit revision was completed in 2013 and
resubmitted in January 2014. The revision includes expansion of surface and
underground mining operations and an updated reclamation plan consistent with
current reclamation practices.

Development of an application to the NRC for a combined Source
Material and By-product Material License to construct and operate the uranium
recovery facility is in an advanced stage of preparation. This license will
allow Energy Fuels to process the uranium ore and produce yellowcake at the
Sheep Mountain Project site. The draft application to NRC for a Source Material
license was reviewed in detail by the NRC in October 2011. The NRC audit report
identified areas where additional information is to be provided. Energy Fuels
anticipates the final application will be submitted in 2014. The review and
approval process for this license by the NRC is anticipated to take
approximately 3 years. Energy Fuels is also evaluating off-site processing
options for this project.

Gas Hills Project

Unless stated otherwise, the following description of the Gas
Hills Project is derived from a technical report entitled National Instrument
43-101 Technical Report Update of Gas Hills Uranium Project Fremont and Natrona
Counties, Wyoming, USA, dated March 22, 2013 (the Gas Hills Technical
Report), prepared by Richard L. Nielsen, PhD., CPG, Thomas C. Pool, P.E.,
Robert L. Sandefur, P.E., and Matthew P. Reilly, P.E., in accordance with NI
43-101 (the Gas Hills Technical Report). The technical report includes
an updated NI 43-101 compliant mineral resource estimate. Each of the authors of
the Gas Hills Technical Report is a qualified person and is independent of
the Company within the meaning of NI 43-101. The Gas Hills Technical Report is
available under Strathmores profile on SEDAR at www.sedar.com.

The Gas Hills Project was acquired on August 29, 2013 as a
result of the merger transaction between Energy Fuels and Strathmore. See
General Development of the Business  Significant Acquisitions  Acquisition
of Strathmore Minerals Corp. above.



Property Description and Location

The Gas Hills project, located in Fremont and Natrona Counties,
Wyoming, totals approximately 19,000 acres and consists of 918 unpatented lode
mining claims, one State of Wyoming mineral lease, and one private mineral
lease. The properties are in central Wyoming within Townships 31-33 North,
Ranges 89-91 West, 6th Principal Meridian.

Of the 918 claims, 763 are unpatented lode mining claims owned
100% by the Company and are located on public lands administered by the U.S.
Bureau of Land Management (BLM). Ninety-four (94) of the claims are
located on split estate lands where the surface is privately owned, but the
federal government owns the mineral rights. The claims are listed in the BLM
Mining Claim Geographic Index Report (LR2000) with a location date of
June 29 and 30, 1965. The latest assessment year is 2013 and the claims are
shown as Active. Holding costs for the claims include a claim maintenance fee
of US$140.00 per claim payable to the BLM before September 1 of each calendar
year and the recording of an affidavit and Notice of Intent to Hold with the
Fremont or Natrona County, Wyoming clerk (as applicable) at a cost of about $10
per claim. Unpatented mining claims expire annually, but are subject to
indefinite annual renewal by filing appropriate documents and paying the fees
described above

Strathmore entered into an agreement with Elmhurst Financial
Group Inc. (Elmhurst) on October 31, 2007 to purchase 155 unpatented lode
mining claims located in the Rock Hill part of the Gas Hills Project and
additional nearby claims were staked on behalf of Elmhurst, of which 178 are
still held by the Company. A net production royalty of 5% was assigned to
Elmhurst on these claims. No other royalties encumber any other claims in the
Gas Hills project.

Strathmore acquired the State of Wyoming Mineral Lease No.
0-42121 (the Wyoming State Lease) on April 2, 2007. The lease covers
approximately 320 acres in Section 36, Township 33 North, Range 90 West. The
Wyoming State Lease is in place until it expires on April 1, 2017. The Wyoming
State Lease has a royalty of 5% payable to the State of Wyoming.

On July 28, 2010, Strathmore entered into a mineral lease
agreement with James D. Sherlock, Mary Freezer and Donna Robeson as Trustees for
South Pass Land and Livestock Company for two parcels of land: 40-acres at the
Jeep Project and 40-acres at the Day Loma Project (the Sherlock Lease).
The Sherlock Lease is effective for an initial 10-year period with indefinite
10-year renewal periods. The mineral owner was granted a 5% net production
royalty. As the mineral lease holder does not hold title to the surface of these
two parcels, Strathmore entered into a Surface Use and Access Agreement
(SUA) with the surface holder, Philp Sheep Company. The SUA also
includes additional lands at the Loco Lee and Rock Hill projects where
Strathmore controls the mineral rights but not the surface estates.

The majority of uranium deposits targeted for eventual
production lie at depths from surface to approximately 450 feet in the main part
of the Gas Hills Project. Depths to mineralization reach 1,200 feet below the
prospective Beaver Rim to the south. Significant previous drilling and mine
production has occurred on and adjacent to the Companys claims in the Gas
Hills. These surface disturbances mainly consist of drill roads, drill sites,
haul roads, spoil dumps, and reclaimed, mined-out open-pits. On the Companys
claims, the drill pits have been reclaimed as required by State law. All
physical work performed by the company is covered by bonds filed with the
Wyoming Department of Environmental Quality (WDEQ) and the BLM. Several
legacy reclamation programs of historic mining activities are ongoing in the Gas
Hills area, including on lands controlled by the Company. These programs are
carried out by the WDEQ and its Abandoned Mine Lands Division (AML)
with cooperation from the BLM. In addition, several former mill tailings sites
on adjacent lands have been or will be reclaimed and transferred to the U.S.
Department of Energy (DOE) for long-term care and maintenance. All of
this reclamation activity is performed at the sole cost of the state and federal
government.

Prior to any exploration or drilling activities in the Gas
Hills project, the Company is required to apply for drilling permits with the
WDEQ Land Quality Division (WDEQ-LED) and the BLM. Prior to the
issuance of any permit, a reclamation bond is posted by the Company. Strathmore
applied for and was granted eight drilling permits covering parts of six
properties in the Gas Hills project. The State has combined some of the permits.
Reclamation of the disturbed areas has resulted in significant reductions in the
bonds. EFR has four permits still open; drilling can resume at any time, but
will require increasing the bonds.

Accessibility, Climate, Local Resources, Infrastructure and
Physiography

The Gas Hills project is highly accessible via public roads and
highways. The Gas Hills uranium district is near the geographic center of
Wyoming. It is partly in Fremont County and partly in Natrona County, midway
between the cities of Casper and Riverton. Altitude ranges from about 6,000 feet
to over 8,000 feet. A steep north-facing escarpment from 400 to 500 feet high
above the surrounding lands, called the Beaver Divide, extends from the
southwestern part of the district to the east-central and southeastern parts.
The areas north and south of the Beaver Divide are gently rolling semi-arid
sagebrush-covered desert.

Climate in the Gas Hills uranium district is continental
semi-arid, with annual precipitation of 8-12 inches, mostly falling in the form
of late autumnal to early spring snows. The summer months are typically hot, dry and clear except for infrequent rains.
Because of the dry climate, almost all of the streams in the area are ephemeral,
flowing only during storm events or spring snow melt. Winters are cold and
summers are hot. Year-round open-pit mining operations were successfully carried
out previously in the Gas Hills uranium district. Studies have found most common
native vegetation is sagebrush and to a lesser extent, rabbit brush. No
threatened or endangered plants were found on the properties. Mule deer and
pronghorn antelope are common in the region, as are nesting raptors. Small
rodents and rabbits are common. The Greater Sage Grouse, present in the general
area of the project, is being considered for listing as a threatened or
endangered species.

Extensive natural resources production in Wyoming provides a
highly skilled labor force in the region. Population centers within two hours of
the Gas Hills Project include Casper, Riverton, Lander and Rawlins, where labor,
equipment and supplies may be obtained. Paved roads from these cities extend to
the edge of the Gas Hills Project area. Access and haul roads within the project
are graded gravel and are maintained by the State, County and mining companies
operating in the area. Functioning power lines, natural gas lines, telephone and
fiber optic cable are present or and near the Gas Hills Project area. Several
wells producing water for domestic and industrial uses are on or close to the
Gas Hills Project area.

History

The Gas Hills uranium district has historically been one of the
major uranium mining and production regions of the United States. Total
district-wide production totaled approximately 100 million lbs. of uranium from
the mid-1950s to the late 1980s. Following the initial discovery of uranium in
the district in 1953, a staking rush ensued, thousands of mining claims were
staked within a few months, and exploration exposed numerous near-surface
oxidized deposits. Shipments of ore were sent to Edgemont, South Dakota, or to
Vitros mill in Salt Lake City, Utah. By 1959, there were five uranium mills
operating in the region: Lucky Mc, Split Rock, Susquehanna, Federal-American
Partners, and Globe, Inc. In the early-1980s, the spot price of uranium
dropped, and the Wyoming uranium mills were placed on standby and eventually
dismantled. The last mill production in the Gas Hills uranium district occurred
in 1988 at Lucky Mc. Extensive mill site mine reclamation occurred from the late
1980s until the present time.

More than 100,000 exploration and development holes were
drilled in the Gas Hills from the mid-1950s to 1979. Since 1990 only a few
hundred holes have been drilled, nearly all by Strathmore and Cameco. The
various mining companies that explored for and developed uranium deposits in the
Gas Hills during the 1950s-1980s used various estimation methods and terms for
their estimates. Essentially all companies determined uranium values in drill
holes with a gamma-ray probe. Tonnages were determined by various methods: some
were done by polygons constructed around mineralized drill holes, other
estimates were termed statistical where various circles of influence were
constructed around mineralized drill holes and then statistically summed.
Companies routinely used 16 cubic feet per ton for the tonnage factor.

The Day Loma uranium mineralization was discovered in the
1950s and was later owned by Western Nuclear Inc., later acquired by
Phelps-Dodge. Mining by open pit and underground continued to 1977 and resulted
in the total production of 498,381 tons with a grade of 0.248%, yielding
3,284,593 pounds of U3O8. In 1978, Energy Fuels Nuclear (no relation to the
Company) entered into an agreement to purchasethe Day Loma
properties from Western Nuclear and initiated an aggressive drill program in
1978. In April 1979, Pathfinder Mines completed 200 holes at Day Loma,
confirming additional mineralization.

Three mining companies, Gas Hills Uranium, Federal Resources,
and Radorock Uranium, formed a partnership and constructed the central Gas Hills
uranium mill. Through various reorganizations, this group later became known as Federal-American Partners
(FAP). FAP signed an agreement with the Tennessee Valley Authority
(TVA) in the early 1970s to develop uranium ores in the Gas Hills
area. In the early 1980s TVA acquired all of the mining interests of FAP and
subsequently sold them to Power Resources Inc. (PRI, which was later
acquired by Cameco Corporation) in 1991. Cameco maintained many of the claims
until the early 2000s, when they dropped their rights to mineralization deemed
too shallow for in-situ recovery (Loco-Lee and Bullrush), in addition to those
claims considered too close to previously mined open pits (Andria, George-Ver,
Day Loma, Sunset) and mineralization at greater depths (Beaver Rim).

The Loco-Lee deposit lies adjacent to the Day Loma property and
was part of the FAP property. Loco-Lee was sold to PRI/Cameco. Cameco dropped
the mineral rights to Loco-Lee, which were later staked by Strathmore. Past
production figures for Loco-Lee are not available. American Nuclear reportedly
drilled 1,508 holes in Day Loma that provided information for the historical
tonnage and grade estimates. Although, not complete, Strathmore was able to
acquire information on 652 holes from Cameco. FAP designed a Loco-Lee pit in
preparation for mining, and it is evident from shape and extent of the proposed
pit that many of the missing holes contain significant uranium mineralization.

Bullrush consists of several separate uranium deposits about
one to two miles west of George-Ver at the northwestern extreme of Strathmores
Gas Hills area. They are located on property that once was part of FAP, Western
Nuclears (acquired later by FAP), and Union Carbides historical land
positions. There has been significant historical production from the property,
predominantly by open-pit methods and to a lesser extent by underground mining.
The FAP portion was sold to PRI in 1991. Cameco dropped the mineral rights to
Bullrush, and these were later staked by Strathmore. FAP had previously acquired
the Western Nuclear mineral rights in the 1960s. Production records are very
limited; however, by 1961 Western Nuclear mined 105,300 tons grading 0.196% for
412,000 pounds of uranium from four shallow open-pit mines. Later, FAP mined
additional deposits on their portion (Bullrush, Sagebrush, Tablestakes) of the
current property; final production numbers are unknown. On the west side of the
Bullrush Property, Union Carbide developed uranium deposits by open-pit mining.
Their George pits were excavated in the early 1980s to a depth of ~200-250
feet; final production numbers are unknown.

Jeep is a relatively small uranium deposit located about three
miles southwest of Day Loma. It is located on property that once was part of the
FAP land position. There has been no historical uranium production from this
property.

The Rock Hill deposits located in the northeast part of the Gas
Hills project area lie north of Camecos planned in-situ mining area. The
deposits were discovered in the 1950s as surface outcrop radiometric anomalies.
In the 1960s Vipoint Mining Companys (Vipoint) drilling defined
several near surface uranium deposits. Adobe Oil and Gas Company
(Adobe) in 1975 entered into an agreement with Vipont to develop an
open pit mine. During 1977-1981, Adobe drilled about 500 development holes in
addition to 50 core holes to delineate two deposits (Rock Hill and Red Horse)
adjacent to several mined by Union Carbide and Utah Intl/Pathfinder. Total past
production from the Rock Hill property is unknown.

Strathmores property includes portions of the Beaver Rim area,
which is located to the south of the target areas previously discussed herein.
CAM estimated that approximately 500 to 750 holes were drilled above Beaver Rim
prior to 1980. Cameco is currently drilling on their side of the Beaver Rim
property line in an area known as the Allegretti uranium trend. The Allegretti
claim group was previously owned by Adobe. Uranium mineralization in the Wind
River formation was located by drilling in six horizons, each containing roll
type uranium mineralization. Two separate areas about 5,000 feet apart were
explored by historical drilling. Twenty exploration holes were drilled in the
north area, some of which were located on Strathmore property. Of the twenty holes, 18
encountered evidence of mineralization on four levels. The depth of
mineralization is about 1,200 feet.

Geologic Setting

The host for uranium mineralization in the Gas Hills District
is the Eocene Wind River Formation, a continental fluvial sedimentary sequence
consisting of arkosic sandstones with lesser amounts of siltstone, carbonaceous
mudstone, and tuffaceous sandstone.

The uranium deposits are roll-front type, crescent-shaped in
vertical cross section, and with a linear sinuous pattern in plan view. Reduced
uranium minerals, uraninite and a little coffinite are concentrated in the
sandstone matrix in the crescent roll. A concave contact separates the roll from
adjacent bleached and oxidized host rock barren of uranium. This contact is the
roll-front. Upper and lower boundaries of mineralization generally are beds of
impermeable mudstone. Individual rolls can be a few feet to tens of feet thick.
In plan, rolls can be traced for several thousand feet.

Roll-type uranium deposits are formed where oxidized and
soluble uranium is carried down a permeable sandstone bed to a point where it
meets reducing conditions. Uranium is reduced and deposited as uraninite and
coffinite along the roll-front.

Application of current and historical exploration information,
and known geological controls on mineralization, suggest that additional U3O8
could be present in already-identified trends, in addition toareas
where sparse drill information is available, such as the exploration area south
of Beaver Rim, where geological conditions appear favorable. The potential
quantity and grade in these targets is conceptual in nature; exploration
activity has not been sufficient to define a mineral resource, and it is
uncertain if further exploration will result in the targets being delineated as
a Mineral Resource under NI 43-101. The exploration targets identified in the
Gas Hills Technical Report are not reported as a part of any Mineral Resource or
Mineral Reserve. The targets either contain known mineralization as determined
by historical exploration activities or lie adjacent to known uranium
mineralization. Characteristics of each target such as grade, length of the
mineralized trend, width or thickness can only be projected from nearby areas
containing well defined mineralized bodies. These are potential exploration
targets.

Exploration

Strathmores exploration activities focused primarily on the
George-Ver, Frazier LaMac, Loco-Lee, Day Loma, Bull-Rush, Rock Hill, Andrea,
Sunset, Table-Stakes areas within the main Gas Hills area. All of these
properties have a significant historical resource and at least several hundred
historical holes in each property. Beginning in 2007 and continuing to the
present, Strathmores exploration for uranium in the Gas Hills has involved
confirmation drilling of previously-explored areas, along with some step-out
drilling in other areas. Definition of the water table, preliminary
metallurgical tests, and design of a proposed heap-leach pad and recovery plant
were initiated by Strathmore. Exploration and confirmation drilling, in addition
to permitting activities were completed as part of a US$8 million program
formally announced by Strathmore on June 26, 2012 as a part of a strategic
venture with Korea Electric Power Corporation (KEPCO).

Strathmore utilized a prompt-fission-neutron (PFN)
logging tool, gamma-ray probing tools, and select chemical assays for the
measurement of uranium in the Gas Hills project. Equivalent uranium values,
expressed as eU3O8, were obtained from down-hole gamma-ray probes, assuming that
uranium and its daughter products are in radiogenic equilibrium. The probes were
standardized and calibrated using test pits operated by U.S. Department of
Energy, located in Casper, Wyoming and Grand Junction, Colorado.

104

---

Many drill holes completed subsequent to November 11, 2011 were
logged using a PFN logging tool which gives a direct reading of uranium
content.

Strathmore carried out confirmation and development drilling on
the Day Loma, George-Ver, Loco-Lee, Jeep and Rock Hill properties. Each of these
areas has been the site of past mine production and have historical mineral
tonnage estimates. Most of the holes were rotary-drilled, with some
reverse-circulation holes and a few cored sections. Strathmore drilling for each
of the five areas is summarized below.

Day Loma

Strathmore initiated drilling at Day Loma during 2010,
consisting of seven rotary confirmation holes and two monitor wells for
base-line water quality tests. All holes encountered uranium mineralization
varying from 0.012 to 0.355% eU3O8. In 2011, an additional 34 holes were
drilled, including three holes drilled by a reverse circulation rig. These holes
were logged by both gamma-ray and PFN probes. All holes encountered
mineralization ranging from 0.011% to 0.293% eU3O8.

George-Ver

Drilling at George-Ver took place from 2007 to 2010. A total of
25 holes were drilled including seven core holes. Uranium mineralization varies
from 0.007% to 0.261%eU3O8. Generally, chemical assays of core are higher than
the gamma-ray probe measurements.

Loco Lee

The Loco-Lee property was drilled with 15 holes in 2010 and
2011 with three being core. Gamma-ray probe readings vary from 0.019 to
0.404%eU3O8. The 11 holes drilled in 2011 also were logged with a PFN probe to
obtain disequilibrium information. The PFN readings generally were greater than
the gamma-ray probe.

Jeep

Strathmore drilled 40 development holes at the Jeep property in
2007. All holes were logged by standard gamma-ray probe, and readings of up to
0.058% eU3O8were obtained.

Rock Hill

Twelve holes were drilled by a reverse circulation rig at the
Rock Hill property in 2011 to confirm historical drill data and collect bulk
samples for metallurgical needs. Holes were logged with a standard gamma-ray and
PFN probes. Generally PFN probe readings were higher in uranium values than
provided by gamma-ray probes, and vary from 0.01% to 0.104%eU3O8.

CAM concluded from its study of all PFN and gamma readings data
from Strathmores drilling that disequilibrium effects are present and that
actual amount of uranium in the drilled deposits may be greater than those
indicated by the gamma-ray probe.

Mineralization

Uranium mineralization in the Gas Hills is present in bodies
usually referred to as rolls. In vertical cross section, they are irregularly
crescent shaped. Rolls are the result of oxidized and soluble uranium being
transported by ground water to a location within a permeable sandstone host
where a reaction within a reducing environment occurs and insoluble reduced
uranium minerals are deposited. The contact between oxidized and reduced
conditions is called the roll front.

In the body of the crescent, individual rolls range from a few
inches to many feet in vertical thickness. Average thickness of a well
mineralized roll is 10 to 15 feet; many rolls thicker than 20 feet have been
mined. The upper and lower horns of the crescent thin away from the body of the
crescent. In the Gas Hills, the lower horn normally is greatly extended and thins
gradually, whereas the upper horn is short and thins abruptly.

105

---

On the concave side of a crescent-shaped mineralized body,
relatively light gray colored altered host rock is present. The contact is a
slightly irregular narrow zone, and the change from uranium-bearing to bleached
or altered rock normally takes place within a distance of three inches or
less.

On the convex side of a crescent shape mineralized body,
relatively dark greenish-gray unbleached (unaltered) rock is present. The
contact between uranium-bearing and unbleached or unaltered rock is an extremely
irregular interfingering, mostly gradational feature but the contact between
individual fingers of mineralized rock and unbleached host may be moderately
sharp. The fingers of mineralized rock point in the direction of unbleached
rock; this direction can be thought of as the direction in which the roll is
facing.

Upper-limb mineralization dies out away from the body of the
crescent in an abrupt manner somewhat similar to that of the contact between
uranium-bearing and bleached rock on the concave side of the crescent. In
contrast, lower limb mineralization normally terminates gradually in the way
that ore terminates on the convex side of a roll.

Rolls ordinarily are stacked en echelon, forming
multiple mineralized bodies. A series of stacked rolls can be thought of a
frontal system. The number of rolls and vertical separation between them can be
large or small, and as a result, mineralization may occur through a large
stratigraphic interval. In the central Gas Hills district, ore has been found in
a stratigraphic interval almost 300 feet thick.

Un-oxidized mineralization is dark, and usually the darker the
ore the higher the grade. The uranium minerals are very fine grained uraninite
and a little coffinite. The only non-silicate gangue minerals present in
significant amounts are fine-grained pyrite and marcasite, and they are
intimately mixed with uranium minerals.

Uranium is not distributed uniformly throughout a roll, rather,
it is typically concentrated in the body of the crescent close to the concave
side. High-grade mineralization locally contains several percent U3O8per ton. The grade progressively decreases away from the high-grade zone.

Drilling

Prior to the Companys acquisition, Strathmores drilling was
successful in better-defining mineralized areas and in defining NI 43-101
compliant mineral resources, as discussed in the following sections. CAM visited
Strathmores active drilling sites in the main lower Gas Hills district and in
the Beaver Rim area on April 24, 2012, August 7, 2012, and November 7  9, 2012
and verified the drilling procedures described below.

Strathmores practice was to drill holes using 43⁄4 to 51⁄4-inch
diameter bits by conventional rotary drill rigs using air, foam or circulating
drilling mud. The cuttings were collected over 5 foot intervals and laid out on
the ground in rows of 20 samples (100 feet) by the driller. The site geologist
examined cuttings in the field to determine rock type and geochemical
alteration. The geologist also determined when the drill hole is terminated.
Logging trucks are at the drill site and the holes were logged with a gamma
probe and a probe containing a gamma detector and a PFN probe.

In May 2011, Strathmore started drilling in the Gas Hills,
specifically on the Day Loma, George-Ver, Loco-Lee, Bullrush, and Rock Hill
properties, using a reverse-circulation drill rig. A total of 41 holes were
drilled and logged with gamma and PFN tools during the summer 2011. Samples were
collected for mine and mill permitting requirements. This method allows bulk
samples to be collected from surface to total depth (varies from 100-450 feet).
The retrieved mineralized samples are substantial in size and can be used for
mill amenability and column leach testing to determine the ideal leachant and
mill scenario. Holes drilled for environmental monitoring of water are
designated with a number followed by MW in the Gas Hills Technical Report and
are included in the numbering sequence that includes all holes. All holes,
including MW holes were logged by gamma probes, and at times, by the PFN probe.
Late in 2011 and throughout the 2012 drilling campaign, Strathmore searched for
historic drill holes in the principal target areas in the field. When found,
these holes were reamed or re-drilled and logged with gamma ray probe and with
the PFN tool. Locations of the holes were established with GPS surveying. These
recovered historic holes are identified by WO in the respective hole number
within the Gas Hills Technical Report. Beginning in May 2012, prior to the
effective date of the Gas Hills Technical Report, Strathmore used GAA Wireline
Inc. to log holes, and to verify the Strathmore gamma and PFN readings.

Strathmore drilled 60 rotary holes and three core holes in the
Bullrush area in 2012. All holes were logged with a gamma ray probe and a PFN
tool. Eleven confirmation rotary holes and one core hole were drilled in the
area of the historic pit designed by FAP. Strathmore drilled 49 rotary
exploration holes and two core holes in the Bullrush West-29 target area. These
holes were drilled in a grid pattern, with lines spaced 200 feet apart and holes
located at intervals of 200 feet along the lines.

In October 2010, Strathmore initiated drilling on the Day Loma
Property. Nine holes were drilled; seven confirmation holes and two monitor
wells. The seven holes were drilled to confirm mineralization at the Property
and to extend the southeast trend into untested areas. The two monitor wells
were drilled for baseline water quality data collection and analysis as required
for mine permit submittal, and were all logged for uranium. Two areas within the
Day Loma area are considered to have potential for commercial uranium
mineralization. One area lies immediately east and south of the old open pit
mine, called the Day Loma Southeast Extension target. Thirty-eight holes were
drilled in this area, including one core hole in 2012. The second exploration
target area drilled was the Northeast target and 25 holes were drilled in this
area, including one core hole in 2012. Other holes were drilled across the
greater property to confirm the mineralization indicated by the historical
database.

Drilling at the George-Ver property in 2011 and 2012 was
concentrated in three areas located north, west, and South of the historic Lucky
Mc open pit. Twelve rotary holes and seven core holes were drilled in the area
located north and northwest of the old Lucky Mc open pit. The holes were logged
with both gamma probe and PFN tools. Twenty-four rotary holes were drilled west
of the old open pit and 17 rotary holes were drilled south of the old Lucky Mc
open pit. All rotary holes were logged with gamma-ray and PFN probes.

Sixty-five rotary holes and seven core holes were drilled at
Loco-Lee in 2011 and 2012. Thirty-eight rotary holes and six core holes were
drilled to confirm mineralization in the known area of extensive historic
drilling located to the northeast of the old open pits. These holes were drilled
on a grid with lines spaced 100 feet apart and holes located 100 feet apart
along the lines. In addition, thirteen exploration rotary holes also were
drilled in a potential mineral target area north and west of the known
mineralized area with extensive historic drilling.

Strathmore started drilling the Rock Hill Property in April
2011. Twelve holes were drilled by reverse-circulation across the Rock Hill
deposit to confirm existing historical drilling, retrieval of samples for
overburden characterization (mine permit requirement), and for recovery of
mineralized samples for mill amenability and column leach tests. The holes are
located very close to the claim boundary against adjacent land controlled by
others. Strathmore probed each of the twelve 2011 holes, using their standard
gamma and PFN logging tools. Strathmore drilled 26 more confirmation rotary
holes and four core holes in 2012 at the Rock Hill deposit; each of the holes
was logged by gamma and PFN probes. An additional eight (8) confirmation rotary holes were drilled to the
southwest of the Rock Hill mineralization in an area previously mined by Utah
International and planned for mining by Union Carbide.

107

The Tablestakes Project Area is located southeast of
Strathmores past-proposed Gas Hills uranium recovery facility. Part of the
target is an area called Amazon by FAP. Strathmore drilled 13 holes in this
Amazon target area in 2012. Holes are widely spaced and drilled on grid lines
spaced 400 feet apart, and holes located 400 feet apart on the grid lines. Six
(6) additional holes were drilled to the west, in an area of pit highwalls not
mined previously by Union Carbide and FAP. All holes were logged with gamma and
PFN logging probes.

Strathmore carried out exploration drilling at several targets
south of the Beaver Rim Divide during the summer and autumn of 2012. Location,
geologic favorability and previous historic drill testing justified additional
exploration in the area. Strathmore drilled 12 rotary exploration holes in the
West Diamond target and three rotary exploration holes in the East Diamond area.
Nineteen rotary exploration holes were drilled in the South Black Mountain
target area. All holes were logged with the gamma probe and several with the PFN
tool. No core holes were drilled south of Beaver Rim.

Please refer to the Gas Hills Technical Report for the results
of all drilling.

Sampling and Analysis

Sedimentary uranium deposits are most efficiently sampled by
measuring the quantity of radiation emitted along the length of a drill hole and
converting those measurements into equivalent grade and thickness of uranium
mineralization. Such measurements are typically obtained through the process of
down-hole logging with various instruments, supplemented by chemical assays.

Historical Data

The bulk of the drilling on the property was undertaken prior
to 1980, and is considered historical under NI 43-101. Sedimentary roll
uranium deposits were historically sampled by measuring the quantity of
radiation emitted along the length of a drill hole, and converting these
measurements into equivalent grade and thickness of uranium mineralization.
Standard logs consist of recordings of gamma, self-potential and resistivity.
Equivalent U3O8 content was calculated from gamma logs using industry-

standard methods developed by the U.S. AEC. Some check analyses
were done by fluorimetric chemical analyses and closed-can radiometric analyses.
Any differences between the two analyses would indicate a radiogenic
disequilibrium situation where gamma logs did not provide an accurate analysis
of the quantity of uranium present. Chemical analyses for uranium were
historically done at ISO-certified laboratories.

Strathmore Data

Between 2007 and November 11 2011, Strathmore, logged all its
holes with gamma-ray probes. A few core holes were drilled to supplement the
gamma data, and to provide material for metallurgical testing. Strathmore
implemented PFN logging, and select core assaying, in addition to gamma logging.
PFN analysis assesses the quantity of uranium present surrounding a drill hole
directly by measuring neutrons fissioned from the U235isotope, thus
aiding in determining any disequilibrium which may be present.

Data Verification

Validation of the drill hole database is a key element in
preparation of an NI 43-101 report. The drill hole database for the Gas Hills
project consists of thousands of historical drill holes with gamma logs, mostly
from the 1970s, but also with some from as early as the 1950s. It is recognized
that gamma logs are indirect measurements of the amount of uranium present and
must be validated. Typically, this process consists of comparing equivalent
uranium determined from gamma log interpretations with chemical analyses of rock
core recovered from core holes. This process is subject to some degree of
uncertainty because the gamma logs and the chemical assays are obtained
from different samples: core from the drill hole itself and gamma readings from
the material surrounding the hole.

CAM undertook a rigorous statistical comparison of Strathmores
drilling results with those of historical operators, as shown in Section 12 of
the Gas Hills Technical Report. The comparison also included comparison of
historical chemical assays of historical drill core with gamma logs of the cored
intervals, and comparison of Strathmores gamma and PFN logging of the
dual-probed intervals. As a result of these studies, CAM concluded that the
historical drilling at Day Loma and Rock Hill, augmented by Strathmores
drilling, were suitable for use in Mineral Resource estimation. There was not
sufficient comparative data from George-Ver, Loco Lee, or Jeep to allow
estimation of compliant Mineral Resources in these three areas.

Metallurgical Studies

The Companys concept is to mine uranium-bearing material by
open-pit and underground methods, heap-leach the mined material, and recover
uranium by ion exchange. Strathmore previously contracted Lyntek Inc. of Denver,
Colorado, to conduct preliminary metallurgical tests by bottle-roll and
column-leach to assess uranium recoveries. Eight composite samples were prepared
from drill cuttings obtained from drilling at Bullrush-Tablestakes, Day Loma,
George-Ver, Loco-Lee and Rock Hill properties. These were submitted to
InterMountain Labs in Sheridan, Wyoming and to Lyntek for metallurgical test
work. Results of preliminary bottle-roll tests indicate average recoveries of
89.2%; overall reagent consumption is low.

Security of Samples

The historical sampling, logging, and gamma-probing were
subject to the normal industrial security controls typical of the 1950s to
1970s. Strathmores security practices involved: awareness of chain-of-custody
issues, limited access to logging tools through locked storage as approved by
the NRC, and continuing calibration of logging tools to assure that no tampering
occurred. All drill hole physical samples were locked in storage until sent for
laboratory testing.

Beginning in May 2012, Strathmore utilized third-party
independent PFN and gamma logging provided by GAA Wireline Inc of Casper,
Wyoming. GAA operated their own logging equipment and at times, provided loggers
who operated Strathmores company-owned PFN logging truck. GAA provided
calibration documentation of test pit runs, which were also reviewed by CAM.

The Gas Hills Project contains no NI 43-101 Mineral Reserves.

Key assumptions in the resource estimate are as follows:

- CAM reviewed gamma ray, PFN, closed can and chemical assay data for all
  five properties. For Day Loma and George-Ver CAM found that PFN, closed can
  and chemical assay data supported the assumption that the gamma ray eU3O8
  could be used for calculation of indicated and inferred resources. For
  Bullrush, Rock Hill and Loco Lee the data are suitable for estimation of an
  inferred resource but believes that additional chemical, closed can and
  associated PFN and gamma ray data are required for the estimation of indicated
  and measured resources.
- CAM reviewed the geometry in three dimensions of mineral intercepts above
  the grade of 0.035 and a minimum thickness of 1 foot. A content of 0.035%
  eU3O8 corresponds to a contained uranium value of $35 per ton at a $50 uranium
  price. A foot is about the minimum thickness that can be selectively mined by
  open pit methods. This review indicated that likely open pit minable
  mineralization is confined by elevations or depths. These elevations or depths
  were used to define limits for a potentially open pit minable resource.
- Day Loma and George-Ver were historically mined by open pits and by
  underground workings. The areas of historic mining were excluded from resource
  tabulation based on the plan footprint of historic mining. Depending on
  backslope and vertical extent of underground workings, this may be
  conservative.
- Grade thickness and thickness contour maps were constructed using all the
  data and a zero nugget linear variogram. This gives a smooth contour map which
  honors the data. The contour maps were consistent with usual roll front
  deposit geometry but all contour maps showed the connectivity associated with
  potentially minable mineral deposits.
- Limits of mineralization in plan for each of the 5 areas were provided by
  Strathmore. CAM reviewed these and found them to be reasonable so resource
  reporting was additionally constrained to within these areas.
- Based on a the variogram ranges of a minimum about 200 feet and review of
  grade thickness contour maps CAM classified resources as inferred if values
  were interpolated up to 400 ft and extrapolated to 200 feet and were not
  indicated. Resources were classified as indicated if values were interpolated
  up to 282 ft and extrapolated to 141 ft. Note that indicated must also have an
  acceptable equilibrium factor.
- A specific volume of 16.9 cubic feet per ton is suitable for the
  estimation of tonnage and contained pounds. This is based on current
  measurements. Although additional specific volume information should be
  obtained, CAM believes this value is suitable for estimation of an inferred
  and indicated resource.

Using grade thickness contours to calculate resources is
accepted engineering practice for roll front uranium deposits (e.g. NI 43-101
resource report on Sheep Mountain for Titan Uranium, March 2011). If a
contouring algorithm which honors the data is used, the results in terms of
totals are often not dissimilar to the widely-used Nearest-Neighbor method.
However, there is no single contouring package which seems to be preferred in
uranium. CAM examined several different contouring algorithms available in the
public domain and commercially. CAM finally settled on estimation using all the
data with a zero nugget linear variogram. The underlying mathematics of this
estimation technique is the same as kriging but the zero nugget linear variogram
assures that the input data is honored. This is a linear estimator and may be
mathematically shown to give exactly the same total resource as if the roll
fronts were split into individual rolls or by flitches or benches and estimated
using the same contouring algorithm for each unit. This statement, while
mathematically correct, requires careful attention to how individual intercepts
are split between individual rolls or by flinches or benches and how cutoffs are
applied.

Although grade-thickness and thickness maps are very useful as
an aid in visualizing the plan geometry of the roll fronts, a smooth contour map
which honors the data may present the following issues:

- It is possible to have values on the contour map that are greater than the
  maximum or less than the minimum. Typically values greater than the maximum
  are not unreasonable but however in some cases values on the contour map will
  be less than zero.
- If one vertically combines contour maps for several different zones the
  resulting map may not be the same as if one vertically combined the data and
  then re-contoured the totals. This is not a problem with linear estimators
  such as contouring all the data with a zero nugget linear variogram (used for
  the resource estimate), inverse distance and nearest neighbor.
- The behavior of values in front of the nose of the roll is significantly
  different than values behind the nose.
- A smooth contour map that honors the data is inconsistent with the
  geostatistics of roll front uranium which normally has a fairly high nugget.
  Part of this problem is a hit-or-miss nature when drilling near the nose of
  the roll. This inconsistency is also due to the fact that roll front uranium
  data is not covariance stationary (a fundamental geostatistical assumption:
  i.e. one averages things separated by a distance in certain directions and
  then assume these averages apply to everything in the dataset.) This was also
  alluded to in item 3.
- Manual contouring is very time-consuming with the amount of data
  associated with roll front uranium deposits and has a risk of bias.

Mining Operations

Mining operations have been carried out on areas of the Gas
Hills Project at various times in the 1950s to the 1980s as discussed above.
No current mining is occurring on the project.

Permitting

The Gas Hills Project consists of proposed open pit mines with
ore to be processed onsite or at a centrally-located processing facility. The
Company recently completed baseline studies for the Project. Most of the mining
activities proposed for the Project are on Federal lands administered by the
BLM. Strathmore previously submitted a Mine Permit Application and Plan of
Operations (PO) to the WDEQ-LQD and the BLM, respectively, in August
2013. The BLM completed public hearings to advance work on the Environmental
Impact Statement (EIS) pursuant to the National Environmental Policy
Act (NEPA). In late 2013, Energy Fuels requested that WDEQ-LQD cease
review of the Mine Permit Application and that the BLM temporarily delay the EIS
process until the company can fully assess the Projects economics. In March
2014, Energy Fuels withdrew the PO because it became apparent that the mining
and processing plans would need to be significantly revised to optimize the projects economic potential. Energy Fuels continues to
cooperate with the AML Division of the WDEQ to advance reclamation of historic
mining features within the Project area.

La Sal Project

Unless stated otherwise, the following description of the La
Sal Project is derived from a technical report entitled "Technical Report on La
Sal District Project (Including the Pandora, Beaver, and Energy Queen Projects),
San Juan County, Utah, U.S.A.", dated March 25, 2014, prepared by Douglas C.
Peters, CPG, of Peters Geosciences, in accordance with NI 43-101 (the La Sal
Technical Report). The La Sal Technical Report includes an updated NI
43-101 compliant Mineral Resource estimate. The author of the La Sal Technical
Report is a qualified person and independent of the Company within the
meaning of NI 43-101. A copy of the La Sal Technical Report is available under
the Companys profile on SEDAR at www.sedar.com.

Energy Fuels had previously filed an NI 43-101 Technical Report
for the Energy Queen mine in March 2011 entitled Updated Technical Report on
Energy Fuels Resources Corporations Energy Queen Project San Juan County, Utah
March 15, 2011by Douglas C. Peters. The Energy Queen property is
located near the west end of the La Sal Mineral Belt, about three-to-five miles
west of the town of La Sal, Utah. In June 2012, Energy Fuels acquired the US
assets of Denison Mines Corp. (Denison), including the Pine Ridge, Pandora,
Snowball, La Sal, and Beaver mines in the eastern part of the La Sal Mineral
Belt, as well as property between the Beaver and Energy Queen mines, referred to
in this section and in the La Sal Technical Report as the Redd Block.

Peters Geosciences was retained by Energy Fuels to prepare a
new Technical Report to support disclosure of Mineral Resource estimates for the
combined properties now controlled by Energy Fuels in the La Sal Mineral Belt,
herein referred to as the La Sal project. The La Sal Technical Report replaced
the Energy Queen Technical Report; however, it, in part, relies on information
previously disclosed in the Energy Queen Technical Report.



Project Description & Location

The La Sal project consists of four core mineral properties,
from east-to-west, the Pandora/ Snowball, Beaver/La Sal, Redd Block, and Energy
Queen, all located in San Juan County, Utah near the town of La Sal. Other
properties within the La Sal Project include the Pine Ridge property, east of
Pandora, and unpatented mining claims and a Utah State Mineral Lease west of the
Energy Queen mine. The property stretches for 11 miles in an east-west direction
and covers all, or parts of the following Sections: Sections 31, 32, and 33,
T28S, R25E; Sections 4, 5, 6, and 7, T29S, R25E; Sections 25, 26, 31, 32, 33,
34, 35, and 36, T28S, R24E; Sections 1, 2, 3, 4, 5, 6, 7, 11, and 12, T29S,
R24E; Section 36, T28S, R23E; and Sections 1, 2, and 12, T29S, R23E, SLBM, San
Juan County, Utah.

The La Sal project is held by Energy Fuels subsidiaries, EFR
Colorado Plateau LLC and Energy Fuels Resources Corporation under private surface use and access leases,
private mineral leases, Utah State Mineral Leases, San Juan County surface use,
access, and mineral lease, and 272 unpatented mining claims on land managed by
the U.S. Bureau of Land Management or U.S. Forest Service, that are either owned
by Energy Fuels (110 claims), leased by Energy Fuels (129 claims), or under an
option to lease or purchase (33 claims). The total land package consists of
approximately 10,600 acres. The unpatented claims cover about 4,300 acres, the
eight Utah State leases total approximately 2,800 acres, the San Juan County
leased land contains just over 263 acres, and the six separate surface access
and nine private parcel mineral leases apply to a total of 3,200 acres. The La
Sal Project consists of four core properties, from east-to-west,
Pandora/Snowball, Beaver/La Sal, Redd Block, and Energy Queen. Other properties
within the La Sal Project include Pine Ridge east of Pandora and unpatented
mining claims and a Utah State Mineral Lease west of Energy Queen. The property
covers all, or parts of the following Sections: Sections 31, 32, and 33, T28S,
R25E; Sections 4, 5, 6, and 7, T29S, R25E; Sections 25, 26, 31, 32, 33, 34, 35,
and 36, T28S, R24E; Sections 1, 2, 3, 4, 5, 6, 7, 11, and 12, T29S, R24E;
Section 36, T28S, R23E; and Sections 1, 2, and 12, T29S, R23E, SLBM, San Juan
County, Utah.

All La Sal Project property holdings are in good standing.
Unpatented mining claims expire annually, but are subject to indefinite annual
renewal by filing the appropriate documents and paying the fees as described
above. Annual holding costs consist of rental fees to the BLM at
$140/year/claim, due on or before September 1st each year. An affidavit of the
payment to the BLM must be filed with the appropriate County each year for a
nominal fee of about $10 per claim. This applies to all unpatented claims
whether owned or leased by Energy Fuels.

Claims Owned by Energy Fuels:

Beaver/La Sal Area: Energy Fuels owns 21 unpatented claims
covering parts of the Beaver/La Sal and Snowball Mines. These are Snowball 1 and
2; Beaver 22-28; Robin 1-5; Fisher and Fisher 1-3; Chuck 1 and 2; and Cal
Fraction. The claims lie in Section 35, T28S, R24E, Section 31, T28S, R25E, and
Section 1, T29S, R24E.

Energy Queen Area: Energy Fuels owns 56 unpatented claims
covering part of the Energy Queen Mine Mineral Resources and west of the Energy
Queen property. In March 2009, Energy Fuels purchased 29 claims from BZU
Holdings (Mesa Uranium) in section 1, T29S, R23E. These are the RM/Judas group
and include RM 2, 4, 6, 8, 10, 12, and 14, RM 16-20, RM 22-25, RM 27-30, and
Judas 2-8. There are no royalties on these claims. The Sunnyside 3-8,
Rattlesnake 3, 4, 7, and 8, Buck #1, and Jude #1 and #2 were purchased by Energy
Fuels from Uranium One in December 2010. They lie in Sections 1 and 12, T29S,
R23E. Uranium One reserved an overriding royalty of 1% on these claims which
also are burdened by a 2.5% royalty due to a previous owner of the claims.
Energy Fuels purchased the Judas 10-13, HEC 23, DOD 1-3, and Daisy 1-8 claims in
March 2012 from Kimmerle Mining LLC. Energy Fuels will owe a production royalty
(4% net smelter return) to the seller on those claims. These claims lie in
Section 31, T28S, R24E, Sections 1 and 12, T29S, R23E, and Sections 6 and 7,
T29S, R24E.

Pine Ridge Area: In April 2011, Denison purchased 37 claims on
Pine Ridge from six separate claim owners. Due to some overlap and other
irregularities, Denison amended the Notice of Location with the BLM on 18 of the
claims. Energy Fuels abandoned the other 19 claims and replaced them with 15 new
claims covering essentially the same ground. All of these claims are held
without encumbrances and lie in Section 33, T28S, R25E and Section 4, T29S,
R25E.

Claims Leased by Energy Fuels:

Pandora Claims: Energy Fuels is successor to the Mining Lease
of June 16, 1967 and its several amendments between Robert H. Sayre, Jr. and
American Metal Climax, Inc. and its successors (to Atlas in 1973; to Umetco in 1988) applicable to 104 Pandora
unpatented claims. The claims lie in Sections 1 and 12, T29S, R24E, Section 31,
T28S, R25E, and Sections 5, 6, and 7, T29S, R25E. Production from these claims
is subject to a royalty to Sayres successors of 10% of the contained value of
uranium and vanadium, less certain allowable deductions. Energy Fuels has made
all payments due for production up through December 2012 when the Pandora Mine
ceased production and went into a standby status. No annual advance royalties
are due. The annual BLM fees are the responsibility of Energy Fuels.

Martha Claims: A Mining Lease between Robert H. Sayre, Jr. and
Atlas dated July 11, 1973 applies to 10 Martha unpatented claims at the east end
of the Pandora claims. Energy Fuels is successor to this lease. The terms of the
Mining Lease, with respect to production royalty, are the same as the Pandora
Mining Lease (above). Some production occurred on the Martha claims at the
eastern end of the Pandora Mine. Energy Fuels has made all royalty payments due
for production up through December 2012 when the Pandora Mine ceased production
and went into a standby status. The Martha claims lie in Section 31, T28S, R25E
and Section 5, T29S, R25E. The Mining Lease does not include any requirement for
annual advance royalties. The annual BLM fees are the responsibility of Energy
Fuels.

Mike Claims: The Mike claims are the subject of a Mining Lease
between various individuals who are all part owners of the six Mike claims and
Denison, dated August 1, 2011. That lease supersedes the original 1970 lease
between Umetco and the owners. The claims lie in Section 1, T29S, R24E.
Production royalties are on a sliding scale for both uranium and vanadium
depending on the respective commoditys market price. The uranium royalty varies
from 3% to 8% and the vanadium royalty from 2% to 6% less allowable deductions.

lease is now held by Energy Fuels. The current term of the lease runs through
December 31, 2014; it is renewable for as long as minimum royalty and rental
fees are paid. The surface of approximately 384 acres of the western part of the
lease parcel is owned by Charles Hardison Redd. Energy Fuels has a surface
access agreement with Redd. The eastern part of ML-18301 surface is owned by SITLA. Rights to necessary surface use are granted by the
mineral lease. The eastern part of the Beaver/La Sal Mine lies within this
lease. The lease is held by paying in advance an annual rental of $1.00 per acre
and an annual minimum royalty based on the previous January through Novembers
average uranium and vanadium market prices. Energy Fuels has made the rental
payment of $640 and the minimum royalty payment in the amount of $11,471for the
2014 lease year. Rentals and annual minimum royalties are credited against
actual production royalties for the year in which they accrue. The production
royalty on this and other Utah SITLA Leases is 8% on uranium and 4% on
vanadium.

Private Mineral Leases:

Superior Uranium - Energy Queen Mining Lease: Energy Fuels
Resources Corporation entered into a 30-day option to lease the Energy Queen
surface rights with Markle Ranch Holdings, LLC on November 15, 2006. A lease was
signed on December 15, 2006 for a term of twenty years, which is extendable if
mineral production is on a continuing basis. The lease gives Energy Fuels the
right to use any of the 702 acres for exploration, development, or mining
purposes. Rental is at the rate of $50.00 per acre for those acres disturbed by
such activities, currently about 60 acres, and $10.00 per acre for the remaining
undisturbed acreage. Markle also will be paid 1% of market value for any
material mined on adjoining properties, if such minerals are removed by use of
the mine shaft located on the Markle property. Energy Fuels also entered into a
30-day option to lease the Energy Queen mineral rights from Superior on November
15, 2006. A Mining Lease Agreement was signed on December 13, 2006 for a term of
twenty years, which is extendable if mineral production is on a continuing
basis. The mineral lease and surface lease cover the same 702 acres located in
most of Section 6 and the N 1⁄2 NE 1⁄4 and NE 1⁄4 NW 1⁄4 Section 7, T29S, R24E. There
are annual payments due on the lease anniversary dates of $50,000, which are
advance royalties that will be credited against production royalties. Production
royalty will be paid on a sliding scale for both uranium and vanadium from 4% to
8%.

Redd Royalties Block 1-A Mining Lease: The leased parcel
referred to as Redd 1-A covers 160 acres in the SE 1⁄4 Section 31, T28S, R24E,
immediately north of the Energy Queen Mine. This was once part of a much larger
mining lease dated June 1, 1971 between Union Carbide Corporation and Redd
Ranches, a partnership of 11 members of the Redd family. The other parcels were
released in November 1999.

117

---

Through a succession of assignments, Energy Fuels became owner
of the Mining Lease with the acquisition of Denison in June 2012. An advance
royalty of $3.00 per net mineral acre is paid annually to hold the lease.
Payment is current to hold the lease until July 1, 2014. It is the intent of
Energy Fuels to continue to hold this lease. No mining has occurred on this
parcel yet. Production royalty will be 12.5 % of gross value.

Redd Royalties Block 1-B Mining Lease: The lease referred to as
the Redd 1-B was entered at the same time and in the same form as the Redd 1-A
lease described above, but covering different parcels of land. The Redd 1-B
Mining Lease applies to 1,400 acres lying in the following sections: E 1⁄2 SE 1⁄4,
SE 1⁄4 NE 1⁄4 Section 34 and W 1⁄2 NW 1⁄4 Section 35, T28S, R24E; in Section 2, T29S,
R24E all but the W 1⁄2 NW 1⁄4; the SE 1⁄4, E 1⁄2 SW 1⁄4 and E 1⁄4 NE 1⁄4 of Section 3, T29S,
R24E; and the N 1⁄2 Section 11, T29S, R24E. An annual advance royalty of $6,000 is
paid to hold this lease. Payment is current to hold the lease until July 1,
2014. It is the intent of Energy Fuels to continue to hold this lease. The
production royalty is 12.5 % of gross value.

Redd Royalties La Sal Unit Mining Lease: This lease was entered
into on February 5, 2008 between Denison and Redd Royalties for a 20-year term
to cover some of the land previously part of the Redd 1-A that had been released
from the 1-A lease in 1999. The leased land lies in the following parcels: NE 1⁄4
Section 31, T28S, R24E; S 1⁄2 NE 1⁄4, SE 1⁄4 Section 4, T29S, R24E, and the SE 1⁄2
Section 5, T29S, R24E. It totals about 683 acres. The annual advance royalty to
hold this lease is dependent on the previous 12 month weighted average Ux
Consulting Long Term U3O8 Price (Ux Long-Term price).
At the recent average Ux Long-Term price of greater than $50/lb, the
current annual payment is $13,500. Payment has been made to keep the lease
current until February 5, 2015. No mining has occurred on the subject land. When
it does occur, a market value production royalty will be due on a sliding
scale ranging from a uranium royalty of 4% when the Ux Long Term price is less
than $50/lb. to 10% when the Ux Long-Term Price is greater than $150/lb. The
vanadium market value royalty varies from 2% at a Ryans Notes published value
for V2O5 of less than $3.00/lb. up to 6% if the Ryans Notes published value for
V2O5 ismore than $20.00/lb.

Redd Royalties Pine Lodge Unit Mining Lease: On January 31,
1968, Union Carbide entered a mining lease with Redd Ranches, a partnership of
11 members of the Redd family, for the rights to more than 3,680 acres north and
east of La Sal, Utah. Partial drops occurred along with assignments resulting in
the current lease held by Energy Fuels applicable only to 60 acres described as
SE 1⁄4 SW 1⁄4, E 1⁄2 SW 1⁄4 SW 1⁄4, Section 31, T28S, R25E. Holding costs amount to an
annual $12.00 per net mineral acre, which has been paid until February 2, 2015.
A production royalty is due at the rate of 15% of gross value.

Redd Royalties West Pine Lodge Unit Mining Lease: Denison began
a Mining Lease with Redd Royalties on February 5, 2008 to cover an area
previously in the Pine Lodge Unit (above) that had been dropped from the older
lease. The current lease held by Energy Fuels applies to 100.4 acres described
as W 1⁄2 NE 1⁄4 SW 1⁄4; NW 1⁄4 SW 1⁄4 and Lots 2 and 3, Section 31, T28S, R25E. The annual
advance royalty to hold this lease is dependent on the previous 12 month
weighted average Ux Long-Term price. Annual advance royalties have been paid to
hold this lease current until February 5, 2015 in the amount of $2,000. No
mining has yet occurred on the subject land. When it does, a market value
production royalty will be due on a sliding scale ranging from a uranium royalty
of 4% when Ux Long-Term price is less than $50/lb. to 10% when Ux Long Term
price is greater than $150/lb. The vanadium market value royalty varies from
2% at a Ryans Notes published value for V2O5of less than $3.00/lb. up to 6% if
the Ryans Notes published value for V2O5 is more than $20.00/lb.

Redd Royalties portion of Redd-Mullins Mining Lease: Union
Carbide entered a lease with Katheryn Anne Redd Mullins and ten other members of
the Redd family on April 16, 1973. It covered 50% of the mineral ownership of
280 acres located in S 1⁄2 SW 1⁄4 and S 1⁄2 SE 1⁄4 Section 33, T28S, R24E and SE 1⁄4 SW 1⁄4 and W 1⁄2 SE 1⁄4 Section 34, T28S, R24E. (See Crawford-Keller
and Barton Estate, below for description of the other 50% mineral ownership of
these parcels.) The lease has undergone assignments and amendments. An annual
advance royalty equal to $30.00 per net mineral acre ($4,200) has been paid to
hold this lease current until April 16, 2014. It is the intent of Energy Fuels
to continue to hold this lease beyond that date. The production royalty on the
50% mineral ownership on this leased land is like that due on the other older
leases, such as Redd 1-A. Production royalty is 12.5% of gross value.

Crawford-Keller portion of Redd Mullins Land: A 20-year mining
lease was entered between Denison and the Erma Crawford Family Trust on April 1,
2008. It applies to the Crawfords 25% mineral ownership of 240 acres of land
situated in S 1⁄2 SW 1⁄4 and SW 1⁄4 SE 1⁄4, Section 33, T28S, R24E and SE 1⁄4 SW 1⁄4 and W 1⁄2
SE 1⁄4, Section 34, T28S, R24E. The annual advance royalty to hold this lease is
currently paid in the amount of $625/year each to two individuals through April
1, 2015. This amount is based on a sliding scale determined by the 12-month
weighted average Ux Long-Term price. Production royalty here is variable, based
on a market value ranging from a uranium royalty of 3% when Ux Long Term price
is less than $50/lb. to 8% when Ux Long-Term price is greater than $150/lb. The
vanadium market value royalty varies from 2% at a Ryans Notes published value
for V2O5 of less than $3.00/lb. up to 6% if the Ryans Notes published value for
V2O5 is more than $20.00/lb.

Barton Norton Estate portion of Redd-Mullins Land: Denison
entered a Mining Lease with Joel Norton, representative of the Thora Barton
Norton Estate on April 25, 2008. The lease covers a 50% mineral ownership on 40
acres located in the SE 1⁄4 SE 1⁄4 Section 33, T28S, R24E. The other 50% mineral
right resides with Redd Royalties, described above in the Redd-Mullins Mining
Lease (Section 4.4.7) . The annual advance royalty payment to hold the Barton
Norton mineral lease is based on the weighted average Ux Long-Term price in the
previous 12 months, currently $4,000. The advance royalty is paid through April
25, 2014. It is the intent of Energy Fuels to continue to hold this lease beyond
that date. Production royalty here is variable, based on a market value
ranging from a uranium royalty of 3% when Ux Long-Term price is less than
$50/lb. to 8% when Ux Long-Term price is greater than $150/lb.

San Juan County Mineral Lease: A Metalliferous Mineral Lease
between San Juan County, Utah and Hecla Mining Company was signed April 17,
1967. This gave Hecla the right to explore and mine some 262.69 acres located in
the S 1⁄2 S 1⁄2 Section 32, T28S, R24E and most of the NW 1⁄4 Section 5, T29S, R24E.
Two small private parcels in the NW 1⁄4 Section 5 are excluded. A very small
parcel, 0.18 acre in Section 10, T29S, R24E, is included in the lease. Hecla
assigned 50% interest in the lease to Union Carbide in December 1976 as part of
the Hecla-Union Carbide joint venture. The Hecla-Union Carbide JV operated the
Hecla Shaft (now the Energy Queen Shaft) immediately to the west of Section 5 on
the Superior Uranium Lease. The lease is held by an annual payment of $1.00 per
acre. Energy Fuels has paid the lease to maintain it through December 31, 2014.
It is the intent of Energy Fuels to continue to hold this lease beyond that
date. An amendment to the lease in January 1968 changed the production royalty
to match that used by the State of Utah on its metalliferous leases. When the
Energy Queen Mine (Hecla Shaft) ceased operation in 1983, a development drift
had advanced into the County land by a few tens of feet. Very little, if any,
ore was produced at that time. The drift was developing toward mineral resources
that are part of the Redd Block Mineral Resources described later in this
section. The mineral lease allows for surface use necessary for exploration and
mining.

There are no currently outstanding environmental liabilities to
which the project is subject other than for reclamation for which bonds are in
place.

Permanent structures existing at the Energy Queen site include
the headframe and a metal building containing an office, shop, showers,
warehouse, and the hoist. The compressor is located in a separate building. One
cased vertical ventilation hole was established into the mine working level. A
small water treatment building and settling ponds are located on the San Juan
County land in Section 5. During earlier operations, water was treated with barium chloride to remove
radium.

The Beaver and La Sal Mine are accessed through the La Sal
decline with rubber-tired equipment. Men and supplies enter through this portal.
The principal shop, offices, and warehouse facilities used by all mines in the
district are housed at the surface facilities of the La Sal Decline. There are
large fenced yards as well as buildings for equipment and supply storage. It is
used as a central receiving site for bulk and large orders which are then
distributed to the other Energy Fuels mines in the district and other parts of
the region. The shop areas include facilities specific to electrical equipment,
drills, mobile diesel equipment, and welding. Engineering, geology, safety,
environmental, and mine supervisory and clerk offices are located here. There
are also staff and mine crews dry rooms. Ample ore stockpile space is available
for easy truck load-out for transporting ore to the White Mesa Mill. Electrical
lines and substations exist and are adequately sized for any future production
potential of the Mineral Resources. The La Sal Mine is dry, so no water
treatment facilities are needed.

The surface infrastructure at the Beaver Shaft location
consists of the hoist house, hoist, and headframe. The shaft is 690 feet deep to
the underground haulage level at the loading pockets top grizzlies and 750 feet
total depth. There are three pockets, two of 70 ton capacity and one of 90 ton
capacity. This arrangement allows for separation of ore and waste. The skips
dump into an ore bin from which the ore is trucked a short distance to a
stockpile and subsequently loaded in to the trucks for haulage to the Energy
Fuels Mill. The shaft conveyance system is certified for man trips, although the
routine access for personnel is through the La Sal decline. Another building
houses the compressors which supply compressed air for the underground workings
in the Beaver Mine. Power lines and substations are in place. The Beaver Mine is
a dry mine, therefore, no water treatment facilities exist.

Access into the Pandora Mine is through a decline with
rubber-tired equipment. Surface facilities here are less than at the other
mines. It consists of a small office and shop buildings. A third building with a
dirt floor is used for storage of materials and equipment. Power lines exist to
the mine with enough capacity for the required load of potential future mining.
The Pandora Mine is a dry mine.

In 1980, Umetco was planning to sink another shaft to access
the Redd Block Mineral Resource. The project did not progress too far. The
infrastructure at the Redd Block associated with a possible new shaft consists
of a cleared and leveled site large enough for future construction of all
surface facilities that would be required. The power line and transformers are
installed and the concrete base for a compressor building has been poured. As
mining progresses, a water table in the Salt Wash sandstone host horizon will be
between the current Beaver western mine advance and the east end of the Redd
Block Mineral Resources. Seven monitor wells were installed by Denison around
this proposed shaft site.

Accessibility, Climate, Local Resources, Infrastructure, and
Physiography

The all-weather Utah State Highway 46 is within the Project
boundary for the western 8 miles. Unpaved Forest Service roads access the
eastern part of the Project. All other portions of the Project are accessible
via County or private dirt roads. Surface facilities sufficient to conduct
mining operations exist at the Pandora, La Sal, Beaver, and Energy Queen Mines,
with the exception of the head frame and hoist needing to be refurbished at the
Energy Queen. A water treatment facility will be needed to mine the Energy Queen
and Redd Block deposits. The mines are already serviced by adequate power lines
and other utilities.

The area is semi-arid. Temperatures range between an average
low of 41oFto an average high of 72oF. Less than 10 inches
of precipitation falls per year. Winters are not too severe, although there are
numerous snow storms, the temperature drops below 0oF at times, and
snow can accumulate to over a foot in the lower areas and more than two feet at
times on Pine Ridge. All elevations within 4 miles of the center and west end of the property support moderate growths of
sage and rabbitbrush along with other brush, forbs, cactus, yucca, and grasses.
Higher elevations contain juniper and piñon pine in the rocky soils along with
scrub oak, aspen, and ponderosa pine on Pine Ridge to the east.

La Sal, Utah is a small town, currently home to about 200
people. It has been a hub to area ranchers, uranium and copper miners, and oil
drillers for many years, as well as a supply stop for recreationists. A small
grocery store and post office are located on the highway. The bulk of the
residential sites are within the first mile south of the highway and two miles
west of the store. The State of Utah and San Juan County both have road
maintenance shops in La Sal. Larger population centers of Moab and Monticello,
Utah are 22 miles north and 34 miles south, respectively, from La Sal Junction
on Highway 191. Before the cessation of mining at the Beaver and Pandora Mines
in late 2012, many of the workers also came from the Nucla-Naturita and the Dove
Creek areas of Colorado, each about 55 miles away to the east and south,
respectively. Larger cities with industrial supply houses include Cortez,
Colorado 100 miles to the south and Grand Junction, Colorado about 140 miles to
the north.

The region of the La Sal District Project central area is
characterized by a broad shallow valley of hay fields and pasturelands at an
elevation between 6,400 and 7,000 feet. Hills occur at the west end and even
higher elevations of about 7,800 feet are reached at Pine Ridge on the east end.
The north side of the La Sal area slopes south and southwest, radially away from
the La Sal Mountains, which attain an elevation of 11,817 feet at South
Mountain, six miles to the north (even higher elevations are found farther north
at Mt. Peale, 12,721 feet). The slope consists of bouldery gravels shed from the
mountains, variably covered by wind-blown sandy loam. Underlying sedimentary
rocks dip to the southwest, ranging from steep dips near the mountains to
shallow dips near Highway 46. The shaft at the Energy Queen Mine is near to and
on the south side of the axis of a northwest-trending syncline, so the
underlying rocks are dipping slightly to the northeast with northeasterly dip
increasing progressively southward within the Energy Queen lease. In the area of
the Beaver Mine, the rocks dip about 2.5° to the southwest. The near-surface
gravels are thinner and finer-grained in the Energy Queen Lease area; however,
near the Beaver Mine, the gravels attain a thickness locally of over 120 feet.

History

Numerous underground mines near outcrops in the eastern part of
the La Sal trend (in the La Sal Creek Canyon District) were mined for vanadium
and uranium during the early 1900s. Deeper deposits of the central La Sal trend
(in the area of the La Sal Project) were discovered in the 1960s and developed
for production in the 1970s through vertical shafts and declines. The La Sal
project and La Sal Creek District production through 1980 amounted to about
6,426,000 pounds U3O8 (average grade of 0.32% U3O8) and nearly 29,000,000 pounds
V2O5 (average grade of 1.46%) (Kovschak and Nylund, 1981). Most production in
the district was derived from fluvial sandstones, mainly in the upper part of
the Salt Wash Member of the Morrison Formation of Jurassic age. Sandstone lenses
in the overlying Brushy Basin Member of the Morrison Formation host
uranium-vanadium deposits in some locales. Sometime after World War II
(approximately 1948-1954), exploration work on Morrison Formation outcrops in
the west end of the district resulted in the discovery of the Rattlesnake mine
(open pit) two miles west-southwest of the Energy Queen shaft (U.S. Atomic
Energy Commission, 1959), on claims now owned by Energy Fuels. The Pandora mine
was operated by Atlas Minerals in the 1970s and early 1980s. Umetco Minerals
(Union Carbide) operated the Snowball, La Sal, and Beaver mines during the same
time period. The Energy Queen mine, then known as the Hecla Shaft, was started
in 1979 by the Union Carbide/Hecla Joint Venture. The mine stopped production in
1983 due to inadequate uranium prices. GEUMCO (General Electric Uranium Mining
Company) operated the Pine Ridge mine in the late 1970s, producing from a
sandstone lens in the Brushy Basin Member of the Morrison Formation. Pine Ridge
was acquired by Minerals Recovery Corporation in 1981 which developed a decline
to the Salt Wash Member of the Morrison Formation, but halted operations before
any significant production. Low uranium and vanadium prices forced all production throughout the district to cease
about 1991. Ores from these mines have been successfully processed at the now
dismantled Uravan Mill (Umetco), the now dismantled Moab Mill (Atlas), and the
operating White Mesa Mill, now owned by Energy Fuels.

Denison began producing from the Pandora Mine in 2006 and later
from the Beaver Shaft/La Sal decline following its acquisition of International
Uranium Corporation. The production by Denison, and Energy Fuels following its
acquisition of Denisons US assets, between 2006 and 2012 at the Pandora was
290,000 tons of ore. From 2008 through mid-2012, Denison drilled 225 exploration
and fill-in (confirmation) holes in the project area. Energy Fuels drilled
another 27 holes on the Energy Queen property and the State land to the
northwest of the Energy Queen from 2007 through 2012. Due to declining uranium
prices, production ceased in October 2012 at the Beaver/La Sal and in December
2012 at the Pandora. Both mines were put on a standby status and are currently
maintained in conditions that would allow them to be placed back into production
within a few months time.

Geologic Setting

The Colorado Plateau covers nearly 130,000 square miles in the
Four Corners region of the U.S. The La Sal project and other properties held by
Energy Fuels lie in the Canyon Lands Section in the central and east-central
part of the Colorado Plateau in Utah and Colorado. The Plateaus basement rocks
are mostly Proterozoic metamorphics and igneous intrusions. The area was
relatively stable throughout much of the Paleozoic and Mesozoic Eras with minor
uplifts, subsidences, and tiltings resulting in fairly flat-lying sedimentary
rocks ranging from evaporites, limestones, and marine clastic sediments, through
eolian sandstones, to detritus of fluvial systems.

The significant uranium deposits in the La Sal project occur in
the late Jurassic Morrison Formation. The Morrison comprises two members in the
La Sal area. The lower member, the Salt Wash, is the main uranium host. The
upper part of the Morrison is the Brushy Basin Member; it is from 350 to 450
feet thick. The Salt Wash, approximately 300 feet thick, consists of about equal
amounts of fluvial sandstones and mudstones deposited by meandering river
systems flowing generally toward the east. The Brushy Basin was deposited mostly
on a large mud flat, probably with many lakes and streams. Much of the material
deposited to form the Brushy Basin originated from volcanic activity to the
west. The majority of the uranium production has come from the upper sandstones
of the Salt Wash Member known as the Top Rim (historically referred to as the
ore-bearing sandstone or OBSS), which ranges from about 60 feet to 100 feet
thick.

Light-brown and gray sandstones and conglomerates of the
200-foot thick Cretaceous Burro Canyon Formation overlie the Brushy Basin. These
crop out in the eastern part of the La Sal project (over the Pine Ridge,
Pandora, and La Sal/Snowball areas). This formation contains interbedded green
and purplish mudstones with a few thin limestone beds. The Burro Canyon
Formation is exposed covering the Brushy Basin at the west end of the La Sal
project, on the State sections and claims west of the Energy Queen. Locally,
silicification altered the limestones to chert and some of the sandstones to
orthoquartzite. Orthoquartzite cobbles and boulders litter the Brushy Basin
slopes. In the central part of the La Sal Project (Beaver Mine, Redd Block, and
Energy Queen), the Burro Canyon is covered by a layer of alluvium and gravels
shed from the La Sal Mountains to the north. These gravels vary in thickness
from a thin veneer to over 120 feet thick.

The La Sal District uranium-vanadium deposits are similar to
those elsewhere in the Uravan Mineral Belt. Host rocks within the areas
surrounding the La Sal Project consist of oxidized sediments of the Morrison
Formation, exhibiting red, hematite-rich clastic rocks. Individual deposits are
localized in areas of reduced, gray sandstone and gray or green mudstone (Thamm,
et al., 1981). The Morrison sediments accumulated as oxidized detritus in the
fluvial environment. However, there were isolated environments where reduced conditions existed, such as oxbow lakes and
carbon-rich point bars. During early burial and diagenesis, the through-flowing
ground water within the large, saturated pile of Salt Wash and Brushy Basin
material remained oxidized, thereby transporting uranium in solution. When the
uranium-rich waters encountered the zones of trapped reduced waters, the uranium
precipitated. Therefore, deposits vary greatly in thickness, grade, size, and
shape. Vanadium may have been leached from iron-titanium mineral grains and
subsequently deposited along with or prior to the uranium.

122

---

The uranium- and vanadium-bearing minerals occur as
fine-grained coatings on the detrital grains, they fill pore spaces between the
sand grains, and they replace some carbonaceous material and detrital quartz and
feldspar grains. The primary uranium mineral is uraninite (pitchblende)
(UO2) with minor amounts of coffinite (USiO4OH).
Montroseite (VOOH) is the primary vanadium mineral, along with vanadium claysand
hydromica.

Exploration

Outcrops within a few miles of the La Sal project were explored
by prospectors in the early 20thcentury for their radium and
vanadium content. Prospecting was mostly done by exploring outcrops of the
Morrison Formation in the canyon walls of the east end of the La Sal Trend and
other parts of the Uravan Mineral Belt farther east and the Chinle outcrops to
the south. Beginning about 1936, when several mills were built in the region to
process the vanadium ores, prospecting intensified in the areas of the outcrops.
Shallow drilling on the benches above the outcrops was beginning. Uranium
exploration in the region began in the mid-1940s resulting in the discovery of
the Rattlesnake deposit in about 1948. Improvements in equipment led to
increased amounts and depths of drilling. The USGS conducted extensive uranium
exploration and geologic evaluation in the entire region from the late 1940s,
resulting in numerous publications. The Rattlesnake deposit is the only
outcropping uranium deposit on the Energy Fuels La Sal Project property. All
other exploration on the Project has been by drilling, described below. During
the operation of the underground mines, longhole drill programs are essential to
explore for mineralized material not found by the surface holes. This is
especially helpful if the surface hole spacing is larger than about 100
feet.

Mineralization

The uranium- and vanadium-bearing minerals occur as fine
grained coatings on the detrital grains, they fill pore spaces between the sand
grains, and they replace some carbonaceous material and detrital quartz and
feldspar grains. The primary uranium mineral is uraninite (pitchblende) (UO2)
with minor amounts of coffinite (USiO4OH). Montroseite (VOOH) is the primary
vanadium mineral, along with vanadium clays and hydromica. Traces of metallic
sulfides occur. In outcrops and shallow oxidized areas of older mines in the
surrounding areas, the minerals now exposed are the calcium and potassium uranyl
vanadates, tyuyamunite, and carnotite.

Some stoping areas in the Beaver/La Sal and Pandora/Snowball
Mines are well over 1,000 feet long and several hundred feet wide. The Indicated
Mineral Resources of the Redd Block and Energy Queen mine identified through
drilling are of similar size. Individual mineralized beds vary in thickness from
several inches to over 6 feet. Throughout much of the La Sal District there are
three horizons in the Top Rim that host the mineralization. They are 25-40 feet
apart.

Kovschak and Nylund (1981) report no apparent disequilibrium
problems in the other mining episodes of the La Sal area. Mining and milling by
Denison and Energy Fuels shows that well-calibrated gamma probes used by the
mining personnel equate well to the mill head grades indicating no significant
disequilibrium exists. This is generally true of the Salt Wash uranium deposits
because of the age of the mineralization and the hydrologic history of the host
rocks. Therefore, Energy Fuels has no reason to
anticipate any disequilibrium conditions within the unmined portions of the deposits on the project property.

123

Drilling

The area at and around the several mines on the La Sal project was extensively drilled from the late 1960s through early 1980s. The targets were the upper sandstones of the Salt Wash Member of the Morrison Formation. The drilling down dip from the
Rattlesnake mine discovered mineralization locally in Section 1, T29S, R23E (mostly mined-out since then; Energy Fuels has not reviewed any information on the historic drilling in Section 1). Throughout the 1960s and into the 1970s, drilling
progressed westward from the head of La Sal Creek canyon discovering Morrison uranium deposits under several hundred feet of cover (Pandora, La Sal, and Snowball mines). Drilling continued westward and intensified in the later 1970s, discovering
large uranium-vanadium deposits which were developed by vertical shafts (Beaver Shaft and Hecla Shaft). The Redd Block deposit was located and mostly defined in the late 1970s.

In 2008, following the dormant period after Umetco stopped mining at the Beaver and Pandora Mines in 1991, Denison began a drill project at the Pandora mine in an attempt to extend ore being followed in the underground mining operation. The historic
drilling provided the best guide to drill offset holes. From 2008 to 2012, Denison drilled a total of 220 rotary and core holes over the Pandora, Beaver/La Sal Mines and the Redd Block areas. These holes were drilled to verify historical drilling
data and to test the favorable ground adjacent to the mines. Holes were drilled on approximately 100 foot centers where the terrain allowed.  Drill site preparation, drilling operations, and site reclamation were contracted to Reliance Resource LLC.
Denison’s exploration drilling at the La Sal Complex in 2008 and 2009 focused on the East Pandora mining area, southwest and northeast of the existing workings. One hole was drilled to offset a historical mineralized hole and the hole was
cored through the upper level sandstone to assay both uranium and vanadium. During the two year exploration campaign significant mineralization was intercepted in and around the Pandora mine. During 2010, Denison completed 60 rotary holes in close
proximity to mine workings around the Beaver mine and 11 holes at East Pandora. All surface drilling was restricted to areas of private surface ownership. Most of the holes were drilled in relatively close proximity to current mine workings with the
purpose being to identify targets that could be quickly accessed, or to infill areas close to the mine with very spare historical drilling. In 2011 a total of 68 holes were completed, including nine monitor wells. Four holes were cored in the West
Beaver area to assay for both uranium and vanadium. In 2012, a total of 40 rotary holes were drilled in the Redd Block area. No core was taken for the assay analysis. These holes were drilled along the east-west trend of mineralization in the La Sal
project and offset historic mineralization drill hole.

Before purchasing Denison’s USA assets, Energy Fuels drilled 27 holes on the Energy Queen property and the State land to the northwest of the Energy Queen from 2007 through 2012. Energy Fuels’ drilling was done at 100 feet or greater
centers. The purpose of the exploration drilling for Energy Fuels was to verify some of the older drilling, to obtain more stratigraphic information for mine planning of the Energy Queen mine, and to add more resources to the mine inventory.
Drilling, logging and final reclamation were conducted similar to Denison’s exploration program. Energy Fuels’ drilling discovered uranium grades comparable to historical drill holes.

Twenty holes were drilled by Energy Fuels at the Energy Queen from October, 2007 to January 2008 totaling 14,450 feet. Energy Fuels’ drilling proved strong east-west and north-south trending mineralized areas in the Salt Wash member of the
Morrison Formation. The following conclusions can be drawn by analyzing this current phase of drilling using the two cross-sections:

- Uranium and vanadium values and thicknesses discovered in the Energy Fuels drilling correlate well with the old (circa 1980) drilling done by Union Carbide.

124

---

- Carbon trash zones in the favorable 45-60-foot thick sandstone (this is
  commonly referred to as the ore-bearing sandstone or OBSS) were an important
  mechanism to fix the uranium- vanadium mineralization.
- Mineralization occurs in a favorable sand (OBSS); it is thick (~60 feet)
  with most of the mineralization forming within 25 feet of the base of the sand
  (~5790 foot elevation). Drill hole EQ-07-16 has a second mineralized zone 47
  feet above the base of the sand (~5825 foot elevation). This is in line with
  the La Sal-Pandora main channel trend.
- Mineralization occurs in favorable sand (OBSS), about 45 feet thick. Holes
  EQ-07-15, 16, and18 have second mineralized zones above the base of the sand.
  Mineralization formed in this thinner sand is controlled by carbon trash
  (usually at the top of the trash zone) and the position of the altered
  mudstones. Mineralization occurred near the base of the OBSS in the north
  extents. Two strongly mineralized zones occur in the central portion, and in
  the south extents, the strong mineralization occurs in the upper portion of
  the OBSS. This is equivalent to the La Sal- Rattlesnake Pit Trend.
- Both channels are strong and well developed, as indicated by an average
  drill offset distance of over 100 feet (from old mineralized holes in the
  preferred direction along course). Alteration is strongest on the top and
  middle splits of the OBSS sand.
- The OBSS sand sub-unit is located 40 -60 feet below the contact with the
  Brushy Basin Member of the Morrison Formation. The uppermost part of the Top
  Rim of the Salt Wash Member lacks lateral continuity, is split by mudstone, is
  finer, and is less permeable. It ranges from semi- favorable to unfavorable
  for mineralization.

Sampling, Analysis and Security of Samples

EFR has not conducted widespread and definitive sampling
related to exploration on the La Sal Project. The equivalent uranium content
(eU3O8) can easily be estimated radiometrically with properly calibrated Geiger
Counters and scintillation instruments. During underground mining, samples are
often collected where the appearance of the rock suggests it is ore-grade, but
the radioactivity is low. This usually represents low uranium content but higher
vanadium content. The samples are assayed for both uranium and vanadium.
Standard industry laboratory practices are used for chemical assaying of uranium
and vanadium.

Core from drill holes is logged for its lithology, scanned with
a Geiger Counter, and any zone of mineralization is split along the axis of the
core. One half is sent for assaying and the other half is retained with the
other core. These tasks were mostly performed by personnel of Union Carbide who
were experienced in uranium exploration, sampling, and analytical methods, and
the summary data appear to be in conformity with technological standards at the
time. EFR and Denison follow similar practices on recent core and will continue
such practices on future core samples.

Conventional rotary drilling produces sand-sized particles
which cannot be assigned an exact footage interval by the time they reach the
surface. Mixing with cuttings from higher in the drill hole can occur;
therefore, they do not yield samples adequate for grade estimation. Instead,
downhole electric and radiometric logging is relied on for rotary holes.
However, assaying of cuttings from ore zones can give an approximate V2O5:U3O8
ratio.

Mineral Resources

Since the La Sal project covers a length of eleven miles and
includes several mines from east to west, the project was divided into four
blocks: Pandora, Beaver/ La Sal, Redd Block and Energy Queen. The mineral
resource estimation for the La Sal project is based on the gamma logs from 1,993
historic rotary drill and core holes, 247 holes drilled by Energy Fuels and
Denison from 2007 to 2012, and approximately 500 underground long holes. Mineral
Resource estimates have been calculated using a modified polygonal method. A
minimum composite intercept GT value (grade X thickness) of 0.10% ft eU3O8 was
used as a cutoff. The mineralization in the La Sal project is interpreted as
being hosted in the Top Rim sandstone of the Salt Wash Member of the Morison
Formation. Total thickness of the host sandstone is between 60 and 100 feet.

Mineral Resource estimates have been made for the La Sal
Project. The Mineral Resources are classified as defined in the National
Instrument 43-101 and in accordance with CIM Standards on Mineral Resources and
Mineral Reserves. They are grouped by logical mining unit subareas and
summarized as follows:

Mining assumptions were used in determining a cut-off grade for
the resource estimates. Mining dilution is 1 foot of waste for mineralized
thicknesses less than 6.0 feet or an appropriate fraction of a foot (if the
intercept is greater than 6 feet) up to 7.0 feet. A resuing or split-shooting
mining approach will be followed to minimize dilution when extracting thin
zones. In the split-shooting method, the mineralization is usually thin (a few
feet in thickness). The eventual stope height will be 7 feet or greater, but at
the time of mining the waste above or below the mineralized horizon is blasted.
This waste layer may be one or more feet thick. After the waste is blasted and
removed, the mineral zone is blasted and removed, thus reducing the amount of
dilution to the mineralized rock. At times, the mineralized zone is blasted
before the waste. For the remaining Mineral Resources in the Project areas, 7.0
feet is the assumed minimum stope height. Mineralized intercepts greater than
7.0 feet are not diluted for resource calculations. It is conservative to use
waste at zero grade for the dilution because there is often lower-grade material
adjacent to the target mineralized zones.

The Mineral Resource estimate for the La Sal Project is
reported by mine areas. Since the Project covers a length of eleven miles and
includes several mines from east to west, the project was divided into four
blocks: Pandora, Beaver/ La Sal, Redd Block and Energy Queen (Plate). The
Mineral Resource estimate for the Energy Queen was presented in the Energy Queen
Technical Report and was revised with new drill holes in the La Sal Technical
Report. Changes to the Energy Queen Mineral Resource from the previous report
are not readily apparent, but result from applying a smaller area of influence
to the drill hole intercepts, using a higher cutoff criteria, and including the
SE 1⁄4 Section 31, T28S, R24E

The Mineral Resource estimation for the La Sal project is based
on the gamma logs from 1,993 historic rotary drill and core holes, 247 holes
drilled by Energy Fuels and Denison from 2007 to 2012, and approximately 500
underground long holes. Mineral Resource estimates have been calculated using a
modified polygonal method. A minimum composite intercept GT value (grade X
thickness) of 0.10% ft eU3O8 was used as a cutoff. The mineralization in the La
Sal project is interpreted as being hosted in the Top Rim sandstone of the Salt
Wash Member of the Morison Formation. Total thickness of the host sandstone is
between 60 and 100 feet. All available geologic data (resistivity, conductivity,
grade, deviation, lithology and stratigraphy) are loaded into Rockworks software
to generate cross sections and to correlate ore horizons between adjacent drill
holes. Cross sections through mineralized zones within the target sandstone
horizon are created with composited grade intercepts and available lithology
data.The sandstone interval in each drill hole is then divided into three zones
within the Top Rim, U1, U2, and U3 from bottom to the top. The interpretation of
mineralized composition is used as the basis for mineral resources
estimation.

In the La Sal Technical Report, a Measured Mineral Resource is
estimated by an area of influence (circle of 50 feet radius) which is assigned
to each drill-hole intercept. Intercepts in surface rotary and core holes, and
underground long holes, were assigned as Measured Resource. Where portions of
polygons are closer than 100 feet, the polygons are altered to half the distance
between holes. The contained metal associated with that drill-hole is calculated
from the thickness, grade and area of influence of the drill-hole intercept.

An Indicated Mineral Resource block is drawn between two drill
holes or among several drill holes which have to meet two criteria: first,
mineralization between and among drill holes has to correlate well within the
same zones (U1. U2. U3), within which the mineralization is believed to be
continuous between drill holes. Secondly, the distance between two drill holes
cannot be over 200 feet apart. Otherwise an Inferred Mineral Resource will be
assigned. No Indicated or Inferred Resources will be calculated between two
holes when mineralization intercepts in these two holes are on different
horizons which does not support the mineralization continuity. The grade and
thickness assigned to a polygon of either Indicated or Inferred Resource blocks
is the smallest grade and thickness of the particular drill holes intercepts
that define each block. Therefore, the Indicated and Inferred Mineral Resource
reported here is conservative.

A density factor of 14 cuft/ton was used in the La Sal
Technical Report. One foot mining dilution is used when the intercept is less
than seven feet thick, otherwise no dilution is assigned. 7.0 feet is the
assumed minimum stope height. Mineralized intercepts greater than 7.0 feet are
not diluted for resource calculations. It is conservative to use waste at zero
grade for the dilution, because there is often lower-grade material adjacent to
the target mineralized zones. The average V2O5:U3O8 ratio from both Pandora and
Beaver/ La Sal mines is 5.25:1 from the recent Energy Fuels Mill head grades
and this ratio is used for the Vanadium Mineral Resources estimate.

Historically, good agreement between polygonal estimation and
as-mined reserves has been found when drill-hole areas of influence are limited
to drill-hole spacings of 100 ft. A review of more recent estimations,
particularly NI43-101 Technical Report compliant resources in the uranium
industry supports the use of this 100 ft. drill-hole separation limitation.

Mining Operations

Mining operations are currently on standby. The mining of all resources in the La Sal project have been by conventional underground methods for over 40 years and, once mining resumes, will continue by such methods. These methods have been used very
successfully in the region for over 100 years. The nature of the Salt Wash uranium-vanadium deposits require a random room and pillar mining configuration. The deposits have irregular shapes and occur within several close-spaced, flat or
slight-dipping horizons. It often rolls between horizons. The use of rubber-tired equipment allows the miners to follow the ore easily in the slight dips and to ramp up or down to the other horizons. The deposits are accessed from the surface via
declines depending on the depth to mineralization and geologically suitable sites for portals, as is the case for the La Sal and Pandora/Snowball mines. Deposits may also be accessed through vertical shafts such as at the Beaver and Energy Queen
Mines. Depending on ground conditions, the shafts will be lined with concrete or with steel and timber-lagging methods. Most recently, the Beaver Shaft was used for hoisting ore, ventilation, and a secondary escape. It is connected underground to
the La Sal mine which provided men and equipment access to the Beaver mine areas. The Salt Wash sandstones are usually quite competent rock and require only moderate ground support. The overlying Brushy Basin mudstones are less competent, so the
declines are often supported by square set timber or steel arch and timber lagging, as is the case at the La Sal and Pandora mines.  The Salt Wash uranium deposits are usually thinner than the mining height needed for personnel and equipment access.
Therefore, the mineralized material is often mined by employing a split-shooting method, which serves to separate ore and waste as it is broken.

Mineral Processing and Metallurgical Testing

The La Sal Trend has a long history of uranium and vanadium production. Deposits from this district have been successfully milled at several historic mills in the region including Union Carbide’s (Umetco) mill at Uravan, Colorado, the Climax
Uranium mill in Grand Junction, Colorado, the Atlas mill at Moab, Utah and Energy Fuels’ White Mesa Mill in Blanding, Utah.  Samples of mineralized material were collected from the Energy Queen Mine waste rock dump. These were used along with
samples from other mines in the region for preliminary testing of amenability to the proposed Piñon Ridge Mill leaching conditions. These results and the historic milling of district ores suggest at this point that the Energy Queen deposit
will present no unforeseen problems with either metallurgical testing or processing. Testing of Energy Queen mineralized material should be performed after the mine is dewatered and rehabilitated to the point that representative samples can be
obtained from in-place rock.

Between November 2012 and April 2013, the Mill processed uranium/vanadium ores from stockpiles of the several previous months’ mining at Beaver /La Sal and Pandora/Snowball Mines.  Recovery rates were greater than 95% for uranium and greater
than 70% for vanadium.

Mining Methods

The mining of all resources in the La Sal Project have been by conventional underground methods for over 40 years and, once mining resumes, will continue by such methods. These methods have been used very successfully in the region for over 100
years.  The nature of the Salt Wash uranium-vanadium deposits require a random room and pillar mining configuration. The deposits have irregular shapes and occur within several close-spaced, flat or slight-dipping horizons. It often rolls between
horizons. The use of rubber-tired equipment allows the miners to follow the ore easily in the slight dips and to ramp up or down to the other horizons. The Salt Wash uranium deposits are usually thinner than the mining height needed for personnel
and equipment access. Therefore, the ore is mined by a split-shooting method.

128

---

The split-shooting mining method involves assessing each face
as the stopes advance by the mine geologist, engineer, mine foreman, or
experienced lead-miner. Because the grades and thickness of the typical Salt
Wash uranium-vanadium deposits are highly variable, they are usually
unpredictable from one round to the next. (A round is a complete mining cycle of
drill-blast-muck-ground support, if needed to be ready to drill again; a normal
round advances a face about 6 feet.)

Typically, the thickness of the mineralized material is less
than the height needed to advance the stope. As the stope face is being drilled,
the blast holes are probed with a Geiger Counter probe in order to estimate the
U3O8 grade. The uranium-vanadium mineralization is usually dark gray to black.
The mineralization sometimes rolls, pinches or swells, or follows cross-beds
within the sandstone. Therefore the miner will also use drill cutting color as a
criterion to help guide blast hole direction and spacing. This irregular habit
of the deposit can result in holes collared in mineralized material ending in
waste, or, conversely, holes collared in waste will penetrate mineralized
material much of their length.

Based on the results of the assessment of the blast holes
drilled in the face, the round will be loaded and shot in two or more stages.
Depending on the location and thickness of the mineralized material in the face
(there may be multiple mineralized layers); the miner will attempt to blast
either only mineralized material or only waste rock. They will muck it out as
clean as possible, then shoot the remaining rock and muck it cleanly. In
resource estimates, one foot of waste is added to the mineralized material for
dilution because of this method. The amount of waste rock shot before or after
the mineralized material results in typical stope heights of eight-to-nine feet.
The minimum height needed to advance the stope is about seven feet, so any
mineralized drill-intercept greater than seven feet does not receive dilution in
resource estimate calculations.

As with the split-shooting method of mining, resuing mining
involves very selective separation of the waste rock from the ore. Ore grade
material is determined by probing drill holes in the face of the stope. In
resuing, waste is blasted or otherwise removed from one side of the ore zone.
The ore in that zone is then extracted, thereby leaving any waste on the other
side of the ore zone in place. If additional stope space is needed or a second
ore zone occurs behind the remaining waste, that waste is removed without
dilution to the ore zones. The lower limit of waste volume that can be extracted
without disturbing ore is a function of the precision with which waste areas of
the drill pattern can be selectively blasted without unduly increasing mining
costs.

Mining assumptions were used in determining a cutoff grade for
the resource estimates. Mining dilution is 1 foot of waste for mineralized
thicknesses less than 6.0 feet or an appropriate fraction of a foot (if the
intercept is greater than 6 feet) up to 7.0 feet. A resuing or split-shooting
mining approach will be followed to minimize dilution when extracting thin
zones. In the split-shooting method, the mineralization is usually thin (a few
feet in thickness). The eventual stope height will be seven feet or greater, but
at the time of mining the waste above or below the mineralized horizon is
blasted. This waste layer may be one or more feet thick. After the waste is
blasted and removed, the mineral zone is blasted and removed, thus reducing the
amount of dilution to the mineralized rock. At times, the mineralized zone is
blasted before the waste. For the Energy Queen Mine, 7.0 feet is the assumed
minimum stope height. Mineralized intercepts greater than 7.0 feet are not
diluted for resource calculations. It is conservative to use waste at zero grade
for the dilution, because there is often lower-grade material adjacent to the
target mineralized zones. Vanadium assays are available for some of the drill
holes. Where no data exist on vanadium content, the intercept is assigned a
value based on the historical Umetco Minerals resource estimate for the property
which averages a V2O5:U3O8 ratio of 4.25:1 based on historic assays of core.
This ratiocannot be guaranteed and must be used only as a historical
estimator for vanadium mineralization potential.

Recovery Method

The White Mesa Mill is a fully licensed uranium and vanadium
mill located in southeastern Utah, near the Colorado Plateau District, the Henry
Mountains Complex, the Arizona Strip and the White Canyon uranium districts. The
Mill is approximately six miles south of the city of Blanding, Utah. Access is
by U.S. highway 191.

Construction of the White Mesa Mill began in 1979, and
conventionally-mined uranium/vanadium ore was first processed in May 1980. The
Mill uses sulfuric acid leaching and a solvent extraction recovery process to
extract and recover uranium and vanadium. The Mill has been operated on a
campaign basis since its initial start-up due to variable uranium market
conditions.

In addition to the conventional ore circuit, the White Mesa
Mill has a separate vanadium co-product recovery circuit. The Mill also has a
third circuit for the processing of certain types of alternate feed materials,
which was built in 2009. This circuit enables the Mill to process both
conventional ore and alternate feed materials simultaneously.

The Mill is licensed to process an average of 2,000 tons of ore
per day and to produce up to 8.0 million pounds of U3O8 per year. In full
operation, the Mill employs approximately 150 people.

Between November 2012 and April 2013, the Mill processed
uranium/vanadium ores from stockpiles of the several previous months mining at
Beaver /La Sal and Pandora/Snowball Mines.

Permitting

The Energy Queen and Redd Block IV mines are located on private
land and were permitted with UDOGM in the early 1980s by Union Carbide. The
Energy Queen was developed and put into production, but the Redd Block IV
project was discontinued soon after the start of construction. A mine and
reclamation plan amendment for the Energy Queen was approved by the UDOGM on
September 22, 2009. This amendment allows the Company to install water treatment
and other new surface facilities to support mine production of up to 250 tpd.
Water discharge permits to allow initial and ongoing discharge of underground
mine water were also approved by the UDEQ in 2009. Energy Fuels initiated
permitting plans for additional mine expansion in 2012, but then deferred these
plans when the Redd Block IV resource was acquired in the Denison acquisition.
Engineering studies are being conducted to determine if the Redd Block IV
resource can be mined economically from the Energy Queen Mine shaft and surface
facilities. If this proves to be the case, the Energy Queen UDOGM permit would
be updated to include the Redd Block IV area as well as other resources that
have been acquired since the 2009 amendment. A Small Source Exemption that is in
place for air emissions would also need to be replaced with an air permit
because of the increased surface disturbance.

The Pandora, Beaver, La Sal and Snowball mines are permitted
with the State of Utah and the BLM/ USFS for current operations. Energy Fuels is
in the process of obtaining combined permits for expansion of the Pandora,
Beaver, and La Sal mines with both UDOGM and the BLM/USFS. Both permit
amendments are in the late stage of permitting. A draft EA was issued for the La
Sal Mines Complex by the BLM and USFS in 2012. A final EA is expected to be
issued in mid-2014. All other permits needed for mine expansion, including the
required air permit, are in place.

Juniper Ridge Project

Unless otherwise stated, the following description of the
Juniper Ridge Project is derived from a technical report entitled "Juniper Ridge
Uranium Project, Carbon County, Wyoming, USA," dated January 27, 2014, prepared
by Douglas L. Beahm, P.E., P.G. and Terrance P. McNulty, P.E., D.Sc., in
accordance with NI 43-101 (the Juniper Ridge Technical Report). The
Juniper Ridge Technical Report includes an updated NI 43-101 compliant Mineral
Resource estimate and Preliminary Economic Assessment (PEA). Each of
the authors of the Juniper Ridge Technical Report is a qualified person and is
independent of the Company within the meaning of NI 43-101. A copy of the
Juniper Ridge Technical Report is available under the Companys profile on SEDAR
at www.sedar.com.

The Juniper Ridge Project was acquired on August 29, 2013 as a
result of the acquisition of Strathmore by Energy Fuels. See General
Development of the Business  Significant Acquisitions  Acquisition of
Strathmore Minerals Corp. above.

Project Description and Location

The Juniper Ridge project is located in southwest Wyoming,
between 6 and 10 miles west of the town of Baggs. Mineral rights associated with
the project include 197 unpatented lode mining claims (the Juniper Ridge
Claims) and one (1) Wyoming State Mineral Lease No. 0-41095 of 640-acres
(the Juniper Ridge Lease). In total, these holdings comprise 4,710
acres. Mineral ownership of the Juniper Ridge Claims resides with the U.S.
federal government, administered by the BLM. Some of the Juniper Ridge Claims
are a split estate with the minerals held by the U.S. and the surface held by
private owners. Mineral ownership of the Juniper Ridge Lease resides with the
State of Wyoming, administered by Wyoming State Lands. The surface of the
Juniper Ridge Lease is held by the U.S. Legal surveys of unpatented claims are
not required. The Juniper Ridge Lease is valid through April 1, 2015, subject to
renewal for successive terms. The Juniper Ridge Claims were originally located
by Strathmore in 2008.



The Juniper Ridge Lease is for an initial term of ten (10)
years, beginning on April 2, 2005, and expiring on April 1, 2015. For the first
five years of the term (prior to commercial mining), the annual rental was $1.00
per acre ($640.00 per year), payable in advance. For years six to ten (the
current period), the annual rental is $2.00 per acre ($1,280 per year), payable
in advance. The State may increase the rental to any rental it believes is fair
and equitable. The Juniper Ridge Lease includes a royalty of five percent (5%)
of the gross value of the uranium bearing ore mined and removed from the land
covered by the Juniper Ridge Lease (the Juniper Ridge Royalty). After a
lease goes into production, the State may reduce the royalty as necessary to
allow the lessee to undertake operations or continue operations with a
reasonable expectation that the operations will be profitable.

131

---

In 2010, Strathmore entered into an agreement to convey the Juniper Ridge Project to Crosshair Energy Corporation (“Crosshair”), as detailed in a news release dated November 1, 2010 which can be found on Crosshair’s profile
on SEDAR.  The Crosshair transaction included a royalty payable to Strathmore. However, Crosshair failed to complete the purchase agreement, the property reverted back to Strathmore in December 2012, and the royalty was cancelled.

Except for the Juniper Ridge Royalty, no royalties, agreements or encumbrances exist on the Juniper Ridge Project. There are no significant factors known by the Company that may affect title, access or the right to perform work on the property.

Mine development will require a number of permits depending on the type and extend of development. Major permits are expected to include a mining permit issued by the WDEQ-LQD and a Plan of Operations approved by the BLM (likely requiring an EIS).
In the event mineral processing occurs on the property (versus transporting the resource to another processing facility), a source materials license from the NRC will be required. No environmental permits have been obtained to date for the Juniper
Ridge Project.

All Juniper Ridge property holdings are in good standing. All unpatented mining claims are subject to an annual federal mining claim maintenance fee of $140 per plain plus approximately $10 per claim for county filing fees. Unpatented mining
claims expire annually, but are subject to indefinite annual renewal by filing appropriate documents and paying the fees described above. The 1872 Mining Law grants certain surface rights along with the right to mine provided the surface use is
incident to the mine operations. In order to exercise those rights the operator must comply with a variety of State and Federal regulations. For the mine operations, Energy Fuels has and/or can obtain, through permitting and licensing of site
activities, sufficient surface rights for the planned operations.

There are no outstanding environmental liabilities to which the project is subject. There is little existing infrastructure on the property.

Please see “Mineralization” section below for the location of all known mineralized zones and mineral resources. Please see “Permitting” section below for the current status of permitting and approvals for the
project.

Accessibility, Climate, Local Resources, Infrastructure, and Physiography

The Juniper Ridge Project is highly accessible via public roads and highways, located between six and ten miles west of the town of Baggs, Wyoming and approximately 3-miles north of the Colorado-Wyoming border.  The project is accessible via
two-wheel drive on existing county and two-track roads by proceeding one mile north of Baggs on Highway 789, then west on Carbon County Road 144 (Poison Buttes Road), toward Poison Buttes.  After approximately six miles, the road crosses into the
Juniper Ridge Project for the next four miles. Mining personnel and supplies can be obtained from towns in the region including Baggs, Rawlins, Rock Springs and Craig, Colorado.

Historic climate records were available through a National Weather Service cooperative station in Baggs until 2000. The Juniper Ridge Project falls within the intermountain semi-desert weather province within the Green and Bear Drainage. Although
winter conditions can be severe, including local ground blizzards, such conditions are not expected to preclude year-round mining or processing operations. The average annual maximum temperature is 58.6° F, and the average annual minimum
temperature is 27.5° F, with maximum monthly average temperatures of 47.6° F to 85.9° F in July and minimum monthly average temperature of 5.8° F to 32.2° F in January. Average annual
precipitation is 10.2 inches, with a maximum depth of snow cover of 2 inches in
November to January.

The Juniper Ridge Project is located within the Wyoming Basin
physiographic province within a small closed subsidiary basin on the southeast
flank of the greater Washakie Basin. The elevation of the property is between
6,000 and 7,000 feet above mean sea level. The topography is characterized by
gently rolling hills which are cut by ephemeral streams draining into the Little
Snake River, located approximately 3 miles south of the property. The dominant
vegetation consists of juniper trees, native grasses, sagebrush and other shrubs
typical of the continental, arid climate of the western United States. The
Juniper Ridge Project is easily accessed. However, project development and
operations will require the installation of some infrastructure, including
utilities and water supplies. Utility services, including natural gas,
electricity and communications are located in Baggs. Water can be obtained from
locally permitted and constructed wells or from nearby surface water sources,
including the Little Snake River. Water rights for both surface and groundwater
are administered by the Wyoming State Engineers Office and are subject to prior
water rights.

History

Uranium was first discovered in the Juniper Ridge project area
in 1951, and commercial uranium mining occurred intermittently from 1954 to
1966. Seven companies mined uranium from twelve open pits and two shallow
underground mines. During this time, a total of 156,000 tons of mineralized
material with an average grade of 0.172% U3O8 was mined resulting in production
of 536,000 lbs. of uranium. Some of the companies that operated in the region
included Shawano Development Corporation, Trace Elements (later acquired by
Union Carbide Corporation), Teton Minerals, Parker-Thomas, and Leckenby.
Underground mining was conducted by Basin Engineering Company under contract
with Teton Minerals. Mined ores were shipped to a variety of nearby mills
including Union Carbides mills located in Rifle and Maybell, Colorado, Western
Nuclears Split Rock mill near Jeffrey City, Wyoming, and ore buying stations
administered by the U.S. Atomic Energy Commission (the AEC), a
pre-cursor to todays U.S. NRC. Site activities were limited during what is
referred to as the Stretch Out period beginning in the mid-1960s and
continuing into the early 1970s. During this period, AEC supply contracts were
phased out, and private utilities began to enter the uranium mining market. In
1973, Homestead Mineral Corporation (HMC) controlled most mining claims
and leases in the area, with the exception of those properties held by Union
Carbide. Also in 1973, Minerals Exploration Company, in a joint venture with
Urangesellschaft (UG), acquired the Juniper Ridge property from HMC. In
1981, AGIP Mining Group (AGIP) acquired the property from UG, after
which mineral leases and claims were allowed to expire during the ensuing
two-plus decade lull in the uranium market.

In 2005, Strathmore, through Miller and Associates, acquired
the Juniper Ridge Lease and located the lode mining claims that comprise the
Juniper Ridge Project. On January 30, 2007, Strathmore entered into a joint
venture with Yellowcake Mining Inc. to develop the property, which was later
dissolved in December 2008. On November 1, 2010, Crosshair entered into an
agreement to acquire the property from Strathmore. However, Crosshair failed to
complete the terms of the agreement, and the property reverted to Strathmore.

Geological Setting

The geological setting within the Juniper Ridge Project is well
documented in the professional literature as well as in internal historical
reports from past operators. The Juniper Ridge Project is located within a small
subsidiary basin of the southeast flank of the Washakie Basin, encompassing the
majority of the outcropping of the Browns Park Formation which was preserved in
the basin over an area of approximately ten square miles. This basin and the larger
Powder Spring Basin, about 15 miles to the west, appear to be small tectonic
grabens down-dropped post-Eocene, but pre-Browns Park in time.

133

---

The dominant structure of the area, directly related to the
grabens, are the east-west trending, high-angle, normal faults. These faults are
mapped as bounding the north side of the basins, but in all probability they
bound the south side as well. Although these east-west faults trend into the
Poison Basin, they do not appear to affect the Miocene rocks, and thus are dated
as being pre-Miocene.

While formations ranging in age from Cretaceous to Quaternary
are exposed at the surface in the vicinity, only Eocene and Miocene formations
play a significant role in the location and tenure of mineralization. Upper
Eocene and Miocene age sediments fill the Poison Basin. Oligocene rocks are
absent, having been completely eroded away before the Miocene deposition.
Miocene rocks lie unconformably on the upper Eocene rocks in the basin and host
the known uranium mineralization within the project area.

Exploration

The initial discovery of mineralization was based on ground
radiometric surveys reported in 1953. Since that time, most exploration work has
focused on drilling which is discussed in Drillingsection below.

The most recent of the historic technical studies (Pincock,
Allen, & Holt, 1986) state that the study was based on radiometric sampling
(geophysical logging) from 5,423 drill holes in the vicinity of the property
comprising 868,000 feet, of which 4,871 of these drill holes were located on the
AGIP mineral properties. The previous historic feasibility study (Pincock,
Allen, & Holt, 1978) states that their mineral resources/reserve estimates
were based on radiometric assays from 3,935 drill holes.

The previous historic technical studies and reports also
address radiometric equilibrium. The data available over time for evaluation of
radiometric equilibrium also varied. In 1982, an internal project summary report
(Beahm, 1982) radiometric equilibrium was evaluated based on data from 200 core
holes. For that study, only core holes with greater than 80% sample recovery
were included and only samples with uranium grades greater than 0.04% U3O8 were
used. This study reported a positive disequilibrium factor of 1.017:1 (chemical
to radiometric). The subsequent feasibility study (Pincock, Allen, & Holt,
1986) evaluated individual core samples representing a total of 321.5 feet of
core, but does not specify the number of core holes from which the samples were
taken. Independent sampling and assaying of core and independent radiometric log
determinations were completed by the authors of the 1986 report. They concluded
that while there was some bias in the estimation of mineralized thickness based
on radiometric interpretation, there was no bias in grade. The older feasibility
study by UG (Pincock, Allen, & Holt, 1978) evaluated radiometric equilibrium
based on 125 mineralized intervals from three separate geographical areas at a
0.02% minimum grade U3O8. This study recommended an adjustment of grade by an
overall negative disequilibrium factor of 0.90.

The historic data utilized to evaluate radiometric equilibrium
in these reports is generally not available for incorporation into this
Technical Report. Current data with respect to radiometric drilling is available
from some 549 recent drill holes.

Mineralization

Uranium mineralization occurs within an eolian stratigraphic
unit of the Miocene Browns Park Formation. The host unit consists of tuffaceous,
feldspathic sandstone which exhibits small to large scale festoon and planar
cross-bed sets ranging up to several feet in thickness. Generally, uranium
mineralization is of the roll-front type, common to the uranium basins in
Wyoming. Localization of uranium appears to relate to permeability and the
presence of pyrite or hydrogen sulphide. The depth of mineralization averages slightly over 100 feet, but ranges from
near the surface to a maximum of 292.5 feet depending on the location within the
basin and the local topography. The deposit is relatively flat lying with
formation dip of less than 5°. The dip of the formation is highest at the
margins of the basin and flatter near the center. The average thickness of
mineralization above a 0.02% eU3O8 cutoff grade is in excess of 10 feet. Two
general areas of mineralization occur within the project, separated by less than
two miles.

134

---

Historic feasibility reports (AGIP, 1986 and UG, 1978) discuss
the continuity of mineralization. These reports express some concerns relative
to the continuity of mineralization, especially with respect to grades necessary
to support mining. AGIPs 1986 report states that continuity at very low grades
(i.e., cutoff of about 80 ppm) is excellent, and mineralization appears nearly
continuously for several thousand feet throughout much of the property area.
However, the degree of continuity decreases with an increasing grade. At grades
above 500 ppm, continuity of uranium mineralization may range from tens of feet
to several hundred feet. Continuity of most mineralized zones is generally less
than 50 feet. Past operations have compensated for the variability in grade by
delineating areas to be mined by drilling on 50-foot centers and instituting
rigorous in-pit grade control programs.

Uranium mineralization within the project is sandstone hosted
and was deposited along a geochemical solution front, as is typical of
roll-front mineralization and similar to other Wyoming sandstone hosted uranium
deposits. The source of uranium is described as syngenetic, as alteration of the
tuffaceous volcanic materials within the Browns Park Formation and/or the
immediately overlying North Park Formation liberated uranium which was
transported by groundwater and concentrated along oxidation/reduction interfaces
within the formation.

Drilling

Available drill data consists of radiometric equivalent data
(eU3O8) for 2,167 historic drill holes and uranium spectral analysis tool
(USAT) assay data for 400 drill holes completed during the 2011 drill
program and 149 drill holes completed in 2012 (all by Crosshair). For the 2011
drill program, downhole logging of the drill holes was completed using standard
gamma technology as well as a USAT, supplied by third party vendor, Century. The
2012 drilling was intended to better define and expand the mineral resource.
Thus, the current database consists of 2,716 drill holes of which approximately
80% are historic and 20% are more recent.

All drill holes, both historic and recent, were shallow (less
than 300 feet) and drilled vertically. The Browns Park Formation is relatively
flat, with dip varying from 5° on the margins to flat in the center. Both grade
and GT distribution are log normal. However, the range was not extreme with a
grade above cutoff ranging from 0.02% eU3O8 to a maximum of approximately 1%
U3O8 and GT above cutoff ranging from 0.10 to just over 5.

Sampling and Analysis

The primary data collected for the project is downhole
radiometric, USAT geophysical log data, and the lithological descriptions of the
drill cuttings. For the 2011 and 2012 drill programs, downhole geophysical
logging was provided by a recognized commercial vendor, Century. The geophysical
log data was provided to Crosshair in electronic format. Lithologic
descriptions, along with drill hole number and survey coordinates, were recorded
on-site with a data recorder. Qa/Qc of the data was completed by the project
manager, and the electronic data transferred to Crosshairs data server with
weekly back up. Seventeen core holes were completed during the 2011 drilling
program primarily to provide samples for metallurgical testing. Following field
lithologic description, the core was placed into plastic sleeves which were sealed to prevent oxidation. The core was then
placed into standard core boxes and temporarily stored in a secure facility
leased from Grieve Enterprises in Baggs, Wyoming.

The author of the Juniper Ridge Technical Report observed the
core storage and examined some of the core which had been collected. The core
samples were sealed in plastic bags to prevent oxidation and stored in core
boxes which were labeled as to the hole number and footage interval. At that
time, no core had been prepared or shipped for assay; however, the basic
protocol of maintaining a chain of custody and obtaining assays from a certified
lab was discussed. No core data was available at the time the Juniper Ridge
Technical Report was prepared. This was not necessary for the mineral resource
estimate as the estimate is based on radiometric equivalent data with the USAT
data utilized to evaluate radiometric equilibrium.

In summary, the data needed for completion of the mineral
resource estimate provided herein was collected and preserved to generally
accepted industry standards and in the authors opinion is appropriate for the
stated purpose of the Juniper Ridge Technical Report.

Data sources for the estimation of uranium mineral resource for
the Project include radiometric equivalent data (eU3O8) for 2,167 historic drill
holes, radiometric equivalent data (eU3O8) and USAT assay data for 400 drill
holes completed during the 2011 drilling program, and radiometric data for 149
drill holes completed in 2012. For the 2011 and 2012 drilling programs, downhole
geophysical logging of the drill holes was provided by a recognized commercial
vendor, Century Wireline of Tulsa, Oklahoma.

In addition to the historical radiometric drill data, 400 drill
holes were completed in 2011 and an additional 149 drill holes in 2012. As with
previous mineral owners, the commercial geophysical logging services of Century
were employed. The 2011 drilling program was intended to verify historic
drilling and replace historic data for drill holes shown on the maps but for
which the radiometric data was not available. The 2012 drilling was intended to
better define and expand the mineral resource. As a result, the current database consists of 2,716 drill holes of which
approximately 80% are historical and 20% are recent.

136

---

Of the 400 drill holes completed in 2011, sixty-nine were
completed within 25 feet of a drill hole with historic radiometric data. With
respect to GT above a cutoff of 0.02% eU3O8:

- Ten 2011holes varied by less than 0.1 GT as compared to historic data.
- Twenty-three 2011 drill holes had a GT that was lower than historic drill
  data by more than 0.1 GT but less than 1.0 GT.
- Eighteen 2011 drill holes had a GT that was higher than historic drill
  data by more than 0.1 GT but less than 1.0 GT.
- Twelve 2011 drill holes had a GT that was lower than historic data by more
  than 1.0 GT.
- Six 2011 drill holes had a GT that was higher than historic data by more
  than 1.0 GT.
- Overall the GT from the 2011 drill holes were slightly lower than the
  comparative historic data.

It is the opinion of the author of the Juniper Ridge Technical
Report that the variances in the comparison of historic and recent data are
related primarily to variations related to continuity of grade rather than
variations in assay methodology and/or equipment. Section 7- Geologic Setting
and Mineralization, discusses the continuity of grade observed in the deposit
and provides an example of the grade variation in closely spaced drilling from
the 2011 program.

In conclusion, it is the authors opinion that current
radiometric database consisting of a mixture of historic and recent dill data is
reliable for the purpose of estimating mineral resources for the following
reasons:

- The historic and current radiometric data were developed by a commercial
  geophysical logging company. The same commercial logging company, Century
  Geophysical Corporation, was employed for both the historic and current
  drilling programs and is one of the principal companies providing such logging
  services for the uranium industry in the US.
- The companies which previously controlled the project area were involved
  in uranium exploration in the US and abroad. These companies followed
  generally accepted industry practices.
- The historic radiometric data was vetted and verified independently for
  two separate technical studies commissioned by the previous owners of the
  Project area.
- The procedures employed during the 2011 drilling program were observed and
  reviewed by the author and followed generally accepted industry practices.
- The 2012 drill data was reviewed by the author and was found to be
  consistent with the 2011 drill data.
- The author has direct personal knowledge as to the veracity of the
  historic database having managed the database during the period of 1982
  through 1986.

Although the results and general conclusions of previous
studies of radiometric equilibrium are known, the historic data utilized to
evaluate radiometric equilibrium in these reports is generally not available.
The current data for evaluation of radiometric equilibrium is available from the
400 drill holes completed in 2011 for which there is both radiometric equivalent
data and USAT data available. USAT logging is a commercially available product.
Calibration of the USAT tool and comparison to chemical assays is provided in
Appendix B of the Juniper Ridge Technical Report. It is the opinion of the
author of the Juniper Ridge Technical Report that this method of assessing
radiometric equilibrium is appropriate and reliable for this project and that
the volume of data is sufficient to reasonably determine radiometric equilibrium
conditions for the purposes of estimating mineral resources.

The initial plane surveying system was established using
standard plane surveying techniques by UG and maintained by AGIP. The survey
control system was created prior to the advent of current GPS technology. When
the author managed the project on behalf of AGIP, all surveying of drill holes,
mining claims, and control for aerial mapping was completed by an independent
Professional Licensed Surveyor (PLS) and all surveying was completed within
accepted mapping standards. Initial drill hole locations were staked out by the
surveyor and the final locations of all drill holes surveyed following drilling.
The surveyor utilized total station survey equipment which provided a digital
record of coordinates and elevation accurate to a few tenths of a foot.

Recent drill hole surveys were completed using a Trimble pro XH
with a pole mounted tornado antenna. Field data was post-processed with Trimble
Pathfinder Office and referenced to three fixed public reference stations.
Recent drill hole surveys were not tied into the on-site control net although
both surveys report coordinates and elevations in the NAD 83 Wyoming State Plane
system. The recent survey methodology should yield sub meter accuracy with
respect to both coordinates and elevation but has not been verified.

The density of mineralized material used in the historic
technical studies, (Pincock, Allen, & Holt, 1986) and (Pincock, Allen, &
Holt, 1978) was 16.3 and 17 cubic feet per ton, respectively. Although there was
some test data available for the determination of density, the data were not
specifically provided in the reports nor were they available for this study. The
previous studies both recommended further testing to determine the density. For
the purposes of the Juniper Ridge Technical Report, the author recommends a
density factor of 16 cubic feet per ton based on direct personal experience with
mining operations in similar sandstone hosted deposits in Gas Hills, Wyoming and
Maybell, Colorado.

The maximum variance in the estimation of mineral resources
based on density in the range of 16 to 17 cubic feet per ton is approximately
6%.

Security of Samples

The core samples were sealed in plastic bags to prevent
oxidation and stored in core boxes which were labeled with the hole number and
footage interval. At that time, no core had been prepared or shipped for assay;
however, the basic protocol of maintaining a chain of custody and obtaining
assays from a certified lab was discussed. No core data was available at the
time the Juniper Ridge Technical Report was prepared. This was not necessary for
the mineral resource estimate as the estimate is based on radiometric equivalent
data with the USAT data utilized to evaluate radiometric equilibrium. In
summary, the data needed for completion of the mineral resource estimate
provided herein was collected and preserved to generally accepted industry
standards and is appropriate.

Mineral Resource and Reserve Estimates

Based on drill density and verification drilling completed in
2011 and 2012, the Mineral Resource estimate for the Juniper Ridge Project meets
the criteria for either Indicated Mineral Resources or Inferred Mineral
Resources, in accordance with CIM Standards on Mineral Resources and Reserves.
No current Prefeasibility or Feasibility Study has been completed for the
Juniper Ridge Project, thus no Mineral Reserves have been reported.

The results of the Juniper Ridge Technical Report estimate that
the project has total Indicated Mineral Resources of 5,280,108 lbs. of eU3O8
contained in 4,598,296 tons with an average grade of 0.057% eU3O8. In addition,
the results of the Juniper Ridge Technical Report estimate that the Juniper
Ridge Project contains 182,100 lbs. of eU3O8 contained in 107,436 tons with an
average grade of 0.085% eU3O8. The authors of the Juniper Ridge Technical Report
utilized a 0.1 GT cutoff based on their experience with successful open pit mining of similar deposits, including
Maybell, Colorado and Gas Hills, Wyoming, which used similar cutoff
criterion.

The recommended base case for estimated mineral resources, as
highlighted in the forgoing tabulation, is the 0.1 GT cutoff. This
recommendation is based upon the experience of the author of the Juniper Ridge
Technical Report with successful open pit mining of similar deposits, including
Maybell, Colorado and Gas Hills, Wyoming, which employed a similar cutoff
criterion and the findings of the PEA.

The primary resource calculation method utilized in the Juniper
Ridge Technical Report is the Grade Thickness (GT) contour method which complies
with the best practice guidelines specific to uranium for the estimation of
mineral resources and mineral reserves adopted by the CIM November 23, 2003 and
it is applicable to this type of deposit.

The mineral resource estimate represents a two dimensional
estimate based on the total GT, by hole, meeting cutoff criteria. The cutoff
criteria applied included: minimum radiometric equivalent grade of 0.02%eU 3O8,
a minimum thickness of 2 feet to account for mine dilution, and a minimum GT of
0.10. Drill data reflecting the thickness (T), grade (eU3O.), and GT was summed
for all intercepts meeting cutoff criteria by hole. GT and T were then contoured
using standard algorithms based upon the geological interpretation of the
deposit. From the contoured GT ranges, the contained pounds of uranium were
calculated by multiplying the measured areas by GT and density. Similarly, the
total tonnage was calculated by contouring thickness and multiplying by area to
obtain cubic feet, then converting to tonnage by applying the density factor.
Tonnage by GT range was estimated based on the ratio of GT areas to total
tonnage and the results summed. A density factor of 16 cubic feet per ton was
utilized in the mineral resource calculation. As discussed in Section 12, Data
Verification, this factor is recommended by the author based on his direct
mining experience in deposits of similar geologic age and genesis.As stated in
Section 10, currently available drill data consists of: radiometric equivalent
data (eU3O8) for 2,167 historic drill holes, radiometric equivalent data (eU3O8)
and USAT assay data for 400 drill holes completed during the 2011 drilling
program, and radiometric equivalent data (eU3O8) for 149 drill holes competed in
2012.

GT contour maps for Juniper Ridge East and West are provided in
the Juniper Ridge Technical Report. Due to the observed variability of grade, as
previously discussed, the projection of mineralization was limited to a maximum
of 25 feet. The spacing of drill data within the areas for which mineral
resources are projected is 100 feet or less. Based on the density of data and
interpretation of geologic continuity, the mineral resource, as calculated, is
considered to meet CIM criteria as an indicated mineral resource.

Evaluation of radiometric equilibrium was based on 258 drill
holes, with natural gamma and USAT data, completed in 2011 which met the cutoff
criteria utilized in the mineral resource calculation. While the average
disequilibrium factor was slightly less than 1 (0.94), the disequilibrium factor
varies by area, ranging from 0.84 to 1.04 with the higher factors corresponding
to the more highly mineralized areas of the deposit. For the purposes of
assessing the overall mineral resources for the Project, it is recommended no
correction for radiometric equilibrium be applied.

With regard to the socioeconomic and political environment,
Wyoming mines have produced over 200 million pounds of uranium from both
conventional and ISR mine and mill operations. Production began in the early
1950s, and continues to the present. The state has ranked as the number one US
producer of uranium since 1994. Wyoming is generally favorable to mine
developments provided established environmental regulations are met (refer to
Wyoming Politicians, Regulators Embrace Uranium Miners With Open Arms, Finch,
2006).

Mine development would require a number of permits depending on
the type and extent of development, the major permits being the mining permit
issued by the State of Wyoming Department of Environmental Quality, Land Quality
Division and the Plan of Operations approved by the BLM. Mineral processing for
uranium would require a source materials license from the US Nuclear Regulatory
Commission. To the
author’s knowledge, these environmental permits have not been obtained. To obtain these permits, it is likely that an Environmental Impact Statement (EIS) would be required.

Portions of the project area are split estate which means that the surface ownership is held privately while the minerals are federal. In these areas, agreements with surface owners will be necessary for mining. Such agreements are currently in
place for the most recent drill program.

To the author’s knowledge, there are no other significant factors that may affect access, title, or the right to perform work on the property.

Mining Operations

Mining operations have been carried out on areas of the Juniper Ridge Project at various times during the 1950’s to the 1970’s. No current mining is occurring on the project.

Feasibility Studies

An economic analysis (“PEA”) of the Juniper Ridge Project is included in the Juniper Ridge Technical Report.  The PEA assumes constant US dollars and a commodity price of US$65.00 per pound. Operating costs include all direct
taxes and royalties, but do not include US Federal Income Tax. The results of the PEA demonstrate that the Juniper Ridge project is expected to generate an Internal Rate of Return (“IRR”) of 22% and a Net Present Value
(“NPV”) of $21,255,000 using an 8% discount rate, after all production related tax and federal income taxes. The PEA demonstrates a pre-tax IRR of 26% and $25,696,000 NPV.  A range of IRR’s and NPV’s were
calculated in the Juniper Ridge Technical Report utilizing different discount rates and uranium prices.

The project is expected to require capital expenditures of $37.5 million, including initial CAPEX of $33.3 million.  First production is assumed to occur in 2019.  In addition, the project is expected to have operating expenses of
US$38.84 per pound of uranium. A total of 5.1 million lbs. of uranium is expected to be mined from the project over a 10-year life, with initial production of 312,000 lbs. in 2019 and maximum production of 665,000 lbs. in 2024.

Permitting

Mine development would require extensive baseline studies and acquisition of several major permits, depending on the type and extent of development. These permits include the mining permit issued by the WDEQ-LQD and the Plan of Operations and EIS
approved by the BLM. Mineral processing for uranium would require a source materials license from the NRC. Portions of the project area are split estate which means that the surface ownership is held privately while the minerals are federal. In
these areas, agreements with surface owners will be necessary for mining. Such agreements are currently in place for exploration drilling.

Mineral Processing and Metallurgical Testing

Current metallurgical testing has not been completed.  However, the deposit has been mined and the product from that mining shipped to conventional mills and recovered.  As documented in Section 6-History, commercial uranium mining occurred
intermittently from 1954 until 1966. Mined product was shipped to a variety of mills including: Union Carbide’s mills located in Rifle and Maybell, Colorado, Western Nuclear’s Split Rock mill near Jeffrey City, Wyoming, and AEC ore
buying stations (Anctil, 1987). These uranium mills were acid leach facilities.

This historical production from the project demonstrates that
uranium is recoverable from the mineralized material. The results of previous
owners metallurgical studies are summarized in the following (Pincock, Allen,
& Holt, 1978) and (Pincock, Allen, & Holt, 1986). While the actual
metallurgical studies are not available, the following table is a summary of
their findings.

Factors which affect mineral processing recoveries and costs
include:

- The grade of the mined material. Thus, the higher the mill feed grade the
  higher the percentage recovery.
- The calcium carbonate concentrations, which in some areas are in the range
  of 6 to 8% (AGIP, 1982).
- If alkaline lixiviant is used, recoveries are expected to be lower than if
  acid lixiviant is used. Alkaline lixiviants have a tendency to cause the clay
  fraction in the leach material to swell which may not be desirable depending
  on the methodologies for mineral processing and tailings disposal.
- In situ recovery is not favorable due to several factors which include
  relatively low permeability of the host rock, lack of confining
  lithostratigraphic units, and because a substantial portion of the
  mineralization occurs above the water table.

The Whirlwind Mine

Unless otherwise stated, the following description of the
Whirlwind Mine is derived from a technical report dated March 15, 2011 entitled
Updated Technical Report on Energy Fuels Resources Corporations Whirlwind
Property (Including Whirlwind, Far West, and Crosswind Claim Groups and Utah

Property Description and Location

The Whirlwind Property is comprised of (i) the Whirlwind claim
group, (ii) the Far West Claim Group, (iii) the Crosswind claim group, and (iv)
Utah State Metalliferous Minerals Lease ML 49312.

The Whirlwind Mine project is located in the Beaver Mesa
district of the Uravan Mineral Belt, along the Colorado-Utah state line four
miles southwest of Gateway, Colorado. The current land position consists of 176
unpatented claims, the Whirlwind, Crosswind, and Far West groups, covering
approximately 3,520 acres, and a 320 acre Utah SITLA Lease ML-49312 for a total
of about 3,680 acres (Energy Fuels dropped 40 of the Far West claims after the
Technical Report was written.) The property is held under four mining leases
with 10-year to 20-year terms, which can be extended. The area was claimed at
earlier times by Umetco Minerals Corporation (Umetco), Atlas, Climax
Uranium, and Pioneer Uravan Inc. (Pioneer Uravan), as well as smaller
companies including Beaver Mesa Uranium, Inc. and Rajah Ventures, Ltd.Unpatented mining claims expire annually, but are subject to indefinite
annual renewal by filing appropriate documents with federal and local
authorities, and paying the fees that total approximately $150 per claim.



The Whirlwind claim group consists of 57 unpatented lode claims
located in the Beaver Mesa mining district, some four miles southwest of
Gateway, Colorado and straddling the Colorado-Utah border. The claims lie in
sections 35 and 36, T51N, R20W, NMPM and sections 1, 2, 11, and 12, T50N, R20W,
NMPM, Mesa County, Colorado and in sections 8, 9, 17, 20, and 21, T25S, R26E,
SLPM, Grand County, Utah. The area encompassed by the claims is approximately
1,085 acres and is covered by the U.S. Geological Survey (USGS) Dolores Point
North 71⁄2 minute topographic quadrangle map.

The Far West claim group contains 74 claims covering approximately 1,480 acres. This group lies to the west and north of the Whirlwind group (which contains a few claims named Far West, also). These claims cover all or part of sections 4, 5, 7, 8,
9, 17, 18, 19, 20, and 21, T25S, R26E, SLPM, Grand County, Utah and parts of sections 25 and 26, T51N, R20W, NMPM, Mesa County, Colorado. They lie on the USGS Dolores Point North and Dolores Point South topographic quadrangles.

The Crosswind claim group is contiguous with the east side of the Whirlwind group. These 45 claims are located in section 6, T50N, R19W, sections 1 and 2, T50N, R20W, Section 31, T51N, R19W, and section 36, T51N, R20W, NMPM, Mesa County, Colorado.
These claims also fall on both the Dolores Point North and Dolores Point South quadrangles.

The land covered by the claims is administered by the BLM. The claim groups surround a half section (about 320 acres) of Utah State Land (section 16, T25S, R26E). Energy Fuels signed an agreement with Energy Metals and its successor, Uranium One, in
May 2008 to acquire this parcel, and that acquisition has been completed. The north central portion of the Whirlwind group borders a 60 acre parcel of private land on three sides (west, south, and east). The northeastern part of the Far West group
borders the north side of the private parcel. The Whirlwind claims were staked over a period of time ranging from January, 2005 through September, 2006. Amendments were made to a few claims to correct defects in descriptions. The Whirlwind Mine
portal is located at latitude 38° 38’ 32” N, longitude 108° 2’ 54” W, at an elevation of 7,050 feet. The Far West property was staked between December 5 and December 29, 2006. Two claims were added to the group on
April 19, 2007 to close a gap immediately north of the Whirlwind Mine portal for mine permit purposes. The Crosswind claims were mostly staked from March 19, 2005 through April 18, 2005, with the last four staked September 4, 2006.

The claims were properly staked on the ground and filed with the two counties and the BLM. The BLM maintenance fees have been paid up through the 2011 payment year. Energy Fuels entered into an option to lease the Whirlwind group (Whirlwind Tunnel,
Whirlwind #2-22, 25-45, Far West 1-13) with Little Maverick Mining Company on September 1, 2006 for 120 days. The lease was signed on December 11, 2006 for a term of twenty years, which is extendable if mineral production is on a continuing basis.
The total advanced royalty paid to Little Maverick over five years will be $3,000,000. Production royalty will be paid on a sliding scale for both uranium and vanadium from 5% to 8.5% of spot price market value, depending upon market prices.
Little Maverick also will be paid a haulage and usage royalty of 1% or 2%, depending on the price of U3O8 and V2O5.

The term of the S&S Mining Company lease for the Far West, et al. group (Far West #15-34, 37-112, Christmas 1-10, and Whirlwind 140-147) is also 20 years (which is extendable if mineral production is on a continuing basis). It was signed on
March 21, 2007. The payment to the Lessor at the time of signing was $400 per claim for the 112 claims in the group ($44,800). The lease contains a production royalty nearly identical to the Whirlwind property, the exception being the top
rate is 8% of market value. Energy Fuels has an exploration and development work commitment of $25,000 per year beginning after the first anniversary date for each of the next three years. There are no annual advanced royalties due for this
property.

The lease between Energy Fuels and High Country Mining Company covering the Crosswind claim group (Crosswind #40-84) was signed March 21, 2007. Its term is also 20 years, which is extendable if mineral production is on a continuing basis. Payment at
signing consisted of $333,334 cash plus $125,000 worth of stock. There is no work commitment contained in this agreement, however, the Lessor has the first right for drilling and ore hauling contracts. The State of Utah reserves a production
royalty on lease ML-49312 of 8% on uranium and 4% on vanadium. Uranium One retained an overriding royalty varying from 2 to 4% on uranium as the spot price varies from $50 to greater than $95 per pound U3O8 and 2 to 4% on vanadium as that
price varies from less than $8 per pound to greater than $22 per pound V2O5.

There is an annual work commitment of $30,000 as part of this
lease assignment from Uranium One. Energy Fuels is responsible for payment of
the Utah annual advanced royalty ($500) and the annual claim rental fees to the
BLM ($140/claim), permitting and bonding fees to the applicable state and county
agencies, and reclamation costs for all of the leases.

All lands held by Energy Fuels for the Whirlwind Mine are
current and in good standing.

Accessibility, Climate, Local Resources, Infrastructure and
Physiography

The Whirlwind Mine portal is centrally located for the combined
properties, being in the north central part of the Whirlwind claim group. It is
accessed by driving 0.8 mile on Colorado Highway 141 south of the Gateway,
Colorado post office to Mesa County Road 4 4/10, the road that goes south into
John Brown Canyon, then by following Road 4 4/10 for 7.4 miles to the
intersection with Mesa County Road 5/10, and then proceeding north and west on
Road 5/10 for 3.2 miles to the mine site. These county roads are mostly graded
dirt with short graveled sections. They are not presently maintained by the
county for their entire lengths during winter months. However, snowfall is
usually manageable for year-round access by a private concern. Energy Fuels made
improvements to Road 5/10 during 2007 and will be responsible for winter
maintenance. A fabric/metal frame shop building was erected in 2007. Phone and
power lines are within a few hundred feet of the portal area; however the power
lines are not energized. Energy Fuels will use generators until the transmission
line to the area is upgraded. Water needed for underground mining is anticipated
to be encountered in the form of ground water during the development and
extraction phases. Presently, groundwater inflow is approximately the amount
needed for mining purposes. Additional water, if needed, can easily be hauled to
the site.

Gateway, Colorado is a very small town currently undergoing a
transition from agriculture to a tourist-based economy. Recently completed
construction at the Gateway Canyons Resort includes a grocery store,
recreational store and tour center, hotel/resort, restaurant, car museum, small
convention center, and employee housing for part of the facility staff.
Additional resort type facilities are being built, and many more are planned by
Gateway Canyons Development. Mine personnel and supplies are available from
Grand Junction (52-miles) and Montrose, Colorado (95-miles).

The region is characterized by mesas cut by deep canyons. There
are narrow benches on the mesa shoulders in some areas and near-vertical,
500-foot cliffs elsewhere. Elevations within the claim group range from 7,900
feet in the southwestern part to 6,800 feet near the canyon rim in the northeast
part. The elevation at Gateway, Colorado, where Highway 141 crosses the Dolores
River, is approximately 4,560 feet.

The area is semi-arid. All elevations support moderate growths
of juniper and piñon in rocky soils along with sage and other brush, forbs, and
grasses. Where soils are rich at the higher elevations and on northern slopes,
there are stands of ponderosa pine and oak brush.

History

This district has seen production of radium, vanadium, and
uranium ores since early in the 20th century. Numerous underground mines on the
Whirlwind property, and surrounding areas within one mile of the claim group
perimeter, have produced in excess of 7,000,000 lbs. U3O8 and nearly 24,000,000
lbs. V2O5. Production is derived from fluvial sandstones, mostly in the upper
part of the Salt Wash Member of the Morrison Formation of Jurassic age. The last
production was in 1990, which ceased due to inadequate uranium prices.

In addition to the older mines on the property, the Whirlwind
Mine was started in 1979 by Pioneer Uravan. It was known then as the Urantah
Mine. Pioneer Uravan stopped the project in 1981, shortly after completion of
the access decline, with only minor production. Drilling by Pioneer Uravan and
others, plus Energy Fuels drilling in 2007, 2008, 2011, and 2012 (10 holes in
Section 16 after the Technical Report was prepared), point to remaining
Indicated Resources at the Whirlwind Mine and adjoining leases of approximately
1,003,320 lbs. U3O8 and 3,293,338 lbs. V2O5. This is contained in about 169,130
tons of undiluted material at a grade of 0.30% U3O8 and 0.97% V2O5. There are
significant, but unquantified resources remaining in the drift ribs and pillars
of several old mines within the three claim groups. The potential to
substantially increase the reported resource is quite reasonable. In addition to
the Indicated Mineral Resource, the Whirlwind Technical Report discusses the
areas which contain a total Inferred Mineral Resource of 2.00 million lbs. U3O8
and 6.47 million lbs. V2O5.

Geological SettingThe Colorado Plateau
covers nearly 130,000 square miles in the Four Corners region, where the state
boundaries of Colorado, New Mexico, Arizona, and Utah meet. The Whirlwind and
other properties currently held by Energy Fuels lie in the Canyon Lands Section
in the central and east-central part of the Plateau in Utah and Colorado. The
Whirlwind Mine is also located in the northern end of the Uravan Mineral Belt.
The Colorado Plateaus basement rocks are mostly Proterozoic metamorphic and
igneous intrusions.

Exploration and Development

Work has proceeded on the permitting, design, and
rehabilitation of the Whirlwind Mine, including acquisition and refurbishment of
mining equipment and timbering, bolting, and arch-set replacement to ready the
Whirlwind decline for production. A mining permit application was prepared and
submitted on July 2, 2007, to the Colorado Division of Reclamation, Mining and
Safety (CDRMS). A PO was submitted to the BLM July 5, 2007. A water
discharge permit has been issued for the Whirlwind Mine and construction of a
water treatment plant and settling tanks has been completed. On September 10,
2008, the Whirlwind permitting process was completed with the approval by the
BLM of the PO for the Whirlwind Mine. Construction of all surface facilities
(clearing, top soil stockpiling, drainage control structures, etc.) necessary
for mine development and production to begin has been completed. The mine was
put on standby, and pumping ceased in December 2009.

Mineralization

The uranium and vanadium bearing minerals occur as fine grained
coatings on the detrital grains, they fill pore spaces between the sand grains,
and they replace carbonaceous material and some detrital grains.

The primary uranium mineral is uraninite (pitchblende) (UO2)
with minor amounts of coffinite (USiO4OH). Montroseite (VOOH) is the primary
vanadium mineral, along with vanadium clays and hydro mica. Traces of metallic
sulfides occur. In outcrops and shallow oxidized areas of the older mines, the
weathered minerals now exposed are the calcium and potassium uranyl vanadates,
tyuyamunite and carnotite. The remnant deposits in the ribs and pillars of the
old mines show a variety of oxidized minerals common in the Uravan Mineral Belt.
These brightly-colored minerals result from the moist-air oxidation of the
primary minerals. Minerals from several oxidation stages are seen in the Packrat
Mine (which is a part of the Whirlwind Mine area), including corvusite, rauvite,
and pascoite. Exposures in the Whirlwind rarely show the colorful oxides because
it was standing full of water until recently.

Some stopes in old mines are over 1,000 feet long and several
hundred feet wide. More often they are 400 feet to 600 feet long and 100 feet to
200 feet wide. The Indicated Resources of the Whirlwind Mine are of similar size. Individual mineralized beds vary in
thickness from several inches up to four feet to five feet. Locally, two or more
mineralized horizons separated by thin waste layers will make a thick mineable
zone of 15 feet to 18 feet.

Drilling

Much of the drilling on the Whirlwind property was performed by
previous operators. Although not actually counted, it is believed that over
1,000 holes have been drilled on the Whirlwind property, and the Crosswind
property has a similar number.

Energy Fuels conducted a drilling project in the summer of 2007
to verify some of the older drilling, explore for additional resources, and to
obtain stratigraphic information for mine planning, particularly for a proposed
drift to connect the Whirlwind Mine to the Packrat mine (one of the historic
mines in the Whirlwind group). This project consisted of 14 holes in Colorado on
the Whirlwind 2, 3, 4, and 13 claims and 14 holes in Utah on the Whirlwind 7, 7
Extension, 8, and 14 claims. The holes totaled 18,580 feet of drilling.
Twenty-five of the holes penetrated the Burro Canyon, Brushy Basin, and Top and
Middle rims of the Salt Wash. The other three holes, numbers WW-07-12, WW-07-13,
and WW-07-14 stopped after penetrating the Top Rim sandstones of the Salt Wash,
which is the host horizon of the bulk of the known resources. Cuttings were
logged with particular attention to sandstone color, carbon content, and
interbedded mudstone characteristics. The holes were probed using a natural
gamma tool along with resistivity and spontaneous potential logs when the holes
contained water. An induction tool was used in holes that were dry. All holes
were also logged with a deviation tool. It is believed that previous operators
also used this method, or a close variant of it. The Colorado Plateau logging
tools were calibrated at the DOE test pits in Grand Junction, Colorado in May of
2007. A follow-up calibration run at the Grand Junction pits in October 2007
showed no statistical difference between calibrations.

In October 2008, Energy Fuels conducted a drilling project on
the Colorado and Utah portions of the Whirlwind property and a portion of the
Far West lease located within the Whirlwind property permit boundary. Eleven
holes, totaling 3,060 feet, were completed in the Far West lease area and served
to meet the work commitment of the Far West lease, explore for resources in the
Lumsden Mine area (one of the historic mines in the Whirlwind group), and give
stratigraphic information in the vicinity of a planned monitor well. There were
three barren holes, four with mineralization from trace to 0.01%, and three with
mineralization between 0.02 and 0.06% . The other hole found 2.5 -0.12%, but
this intercept was in a Brushy Basin sandstone, some 120 feet to 130 feet above
the Top Rim.

There were ten holes, totaling 6,600 feet, drilled on the
Colorado portion of the Whirlwind lease. Three holes were exploring east of the
Whirlwind deposit, closer to the decline. These were barren with thin Top and
Middle Rim sandstones. The other seven holes were offsets in the area of a good
hole drilled in 2007, WW-07-10 (1.5 -0.53%) . Of these, three encountered
ore-grade intercepts, the best being 1.5 -0.67% in the Top Rim. Two found
low-grade mineralization and the other two had a trace. Three of these holes
also found the Middle Rim to be very favorable, including mineralization up to
0.03% .

Five holes were drilled on the SITLA Lease on Section 16. Two
holes were completed by the end of October 2008, totaling 1,340 feet. A third
hole was abandoned because the down-hole hammer broke. An offset to this and two
other holes were drilled in early November (2,060 feet.) to conclude the 2008
drilling at the Whirlwind property. This third hole encountered 1.0 -0.11% U3O8
in the Top Rim along with 2.0 -0.02% a couple feet above. Holes four and five
were drilled just west of the B Area part of the Whirlwind property. Hole 4
had 1.5 -0.13% U3O8and 1.5 -0.04% U3O8 in the Top Rim. The last hole drilled
was barren.

---

Five more holes were drilled in Section 16 in 2011. One of
these encountered a well mineralized interval (1.0 -
0.46%U3O8).Seven holes were also drilled in
the southern part of the Far West group. This area was found to be unfavorable
so the claim block was reduced by 40 claims. After the Technical report was
written, ten more holes were drilled on Section 16 in 2012 further defining
favorable ground, although no significant mineralization was found.

Sampling, Analysis and Data Verification

Energy Fuels has not conducted widespread and definitive
sampling on the Whirlwind and adjoining properties. Previous underground
activity, which resulted in driving the decline and short development headings,
did encounter strong mineralization in one area, but this has not been available
for sampling until recently due to water in the mine. However, the estimation of
resources in the Whirlwind Technical Report has relied upon documentation from
earlier operators. Energy Fuels has employed a conventional combination of
channel sampling, radiometric scanning, and long-hole drilling since the
completion of the rehabilitation of the Whirlwind Decline early in 2008.
Exploration drilling from the surface will continue to be mostly rotary with
down hole electric and radiometric logging, with an occasional core hole likely.

Mineral Resource Estimates

The Whirlwind Technical Report covering all the leased claims
comprising the Whirlwind Mine property estimated an Indicated Mineral Resource
of 169,129 tons of mineralized material grading 0.29% U3O8 and 0.86% V2O5
containing 1.0 million lbs. of U3O8 and 3.3 million lbs. of V2O5. The Whirlwind
Technical Report also states that the Inferred Resources on the Whirlwind Mine
property are 437,100 tons grading 0.23% U3O8 and 0.72% V2O5 containing 2.0
million lbs. of U3O8 and 6.47 million lbs. of V2O5.

Mineral resources were calculated by the polygonal method by
Energy Fuels. Polygons are drawn as perpendicular bisectors between drill holes
or as 100-ft by 100-ft square areas of influence for isolated holes or areas of
equidistant holes on 100-ft centers. The drilling is often on 100 foot centers,
and therefore, many polygons enclose approximately 10,000 square feet of area.
Of course the polygons are smaller where drill spacing is closer, and some may
be slightly larger in clusters of holes with irregular spacing. The polygons are
terminated at the boundaries of other property owners for the generation of the
resource estimate

For the in situresource estimate, the thickness and
grade assigned to each polygon equals that of the intercepts recorded in the
center hole of the polygon. A tonnage factor of 14 cubic feet per ton is used
for Salt Wash deposits. Mining dilution is 1 foot of waste for mineralized
thicknesses less than 6.0 feet or an appropriate fraction of a foot (if the
intercept is greater than 6 feet) up to 7.0 feet. A resuing or split-shot mining
approach will be followed to minimize dilution when extracting thin zones. In
the split-shot method, the mineralization is usually thin (a few feet in
thickness). The eventual stope height will be seven feet or greater, but at the
time of mining the waste above or below the mineralized horizon is blasted. This
waste layer may be one or more feet thick. After the waste is blasted and
removed, the mineral zone is blasted and removed, thus reducing the amount of
dilution to the mineralized rock. At times, the mineralized zone is blasted
before the waste. For the Whirlwind Mine, 7.0 feet is the assumed minimum stope
height. Mineralized intercepts greater than 7.0 feet are not diluted for
resource calculations. It is conservative to use waste at 0% uranium grade for
the dilution because there is often lower-grade material adjacent to the target
mineralized zones. Vanadium assays are available for only a few of the drill
holes. Where no data exist on vanadium, the intercept is assigned a value based
on the historical district average V2O5:U3O8 ratio of 3.24:1. This ratio
cannot be guaranteed and must be used as a historical estimator for vanadium
mineralization potential.

148

---

As with the split-shooting method of mining, resuing mining
involves very selective separation of the waste rock from the ore. Ore grade
material is determined by probing drill holes in the face of the stope. In
resuing, waste is blasted or otherwise removed from one side of the ore zone.
The ore in that zone is then extracted, thereby leaving any waste on the other
side of the ore zone in place. If additional stope space is needed or a second
ore zone occurs behind the remaining waste, that waste is removed without
dilution to the ore zones. The lower limit of waste volume that can be extracted
without disturbing ore is a function of the precision with which waste areas of
the drill pattern can be selectively blasted without unduly increasing mining
costs.

A cutoff of 0.06% U3O8 has been used in all resource estimates
for the Whirlwind and related properties that are based on historic or EFR
drilling results. This cutoff is somewhat subjective and was chosen based on
experience of EFR staff and on the basis of the lowest grade intercepts that are
likely to be mined based on a tentative mine plan and location of such
intercepts in or adjacent to development entries that will be mined regardless
of the grade of involved mineralized sandstone. Assumptions involved in use of
this cutoff are as follows:

| | 1. | Development entries will be made to access indicated and
      measured resources of sufficient size to warrant mining to their locations
      and room-and-pillar mining of the resources. Such entries will follow the
      historic random pattern of mining areas that is driven by the localized
      nature of areas of mineralization.

| | 3. | Measured vanadium grades, in combination with uranium
      grade, can be high enough to warrant mining a resource area even if the

| | 4. | The thickness of the drill intercept in mineralized
      material makes some areas attractive because of available volume of

Mining Operations

Rehabilitation of the Whirlwind Mine was completed in 2007 and
2008. This included acquisition and refurbishment of mining equipment and
timbering, bolting, and arch-set replacement to ready the Whirlwind decline for
production. Construction of the mine facilities were also completed with the
installation of an equipment shop, shower room, office and water treatment
plant. Additionally, mine ventilation equipment and utilities are installed and
roof bolting and ground control work is complete underground. The mine was
placed on standby in November 2008. Pumping ceased in December 2009 and the mine
has refilled with water to near historic levels. It is expected to take about 90
days to pump the water from the mine once operations resume.

Permitting

The Whirlwind Mine has all local, state, and federal permits
needed to mine. A permit application to treat and discharge mine water was
submitted in May 2007 and approved by CDPHE in August 2007. A water
treatment plant and settling tanks were completed in the fall of 2007 under approved exploration plans. In July 2007, mine permit applications were submitted to CDRMS and Mesa County. A PO was also submitted to the BLM in July 2007. Mesa County
approved a Special Use Permit and CDRMS approved a 112D Large Mine Permit for the project in February 2008.

On September 10, 2008, the Whirlwind permitting process was completed with the approval by the BLM of Energy Fuels’ PO for the Whirlwind Mine with a Finding of No Significant Impact. The mine is currently on standby and environmental
monitoring and reporting continues to be conducted at the mine in accordance with permit conditions.

The Sage Plain Project

Unless otherwise stated, the following description of the Sage
Plain Project is derived from the technical report dated December 16, 2011
entitled Technical Report on Colorado Plateau Partners LLC (Energy Fuels
Resources Corporation and Lynx-Royal JV) Sage Plain Project (Including the
Calliham Mine and Sage Mine), San Juan County, Utah and San Miguel County,
Colorado prepared by Douglas C. Peters, Certified Professional Geologist, of
Peters Geosciences, Golden, Colorado in accordance with NI 43-101 (the Sage
Plain Technical Report). The author of the Sage Plain Technical Report is a
qualified person and is independent of the Company within the meaning of NI
43-101. A copy of the Sage Plain Technical Report is available under the
Companys profile on SEDAR at www.sedar.com.

In 2011, EFRC along with Lynx-Royal JV, LLC
(Lynx-Royal), its CPP joint venture partner at the time and subsidiary
of Aldershot Resources Ltd. (Aldershot), acquired several close-spaced
and contiguous leases and mining claims in the area of southeastern Utah and
southwestern Colorado known as the Sage Plain district. In October 2012, Energy
Fuels purchased Aldershots 50% of the JV, and EFRC is now sole owner and
operator of CPP.



Project Description and Location

The Sage Plain Project is located near the southwest end of the
Uravan Mineral Belt. The property lies about 15 miles northeast of Monticello,
Utah. It consists of three private mineral leases, four Utah SITLA Leases, and
94 unpatented mining claims on land administered by the BLM. There are two
historic uranium-vanadium mines within the project area, the Calliham Mine
(which accesses the three private leases) and the Sage Mine (which produced from
the unpatented claims). The combined 5,635 acres of the property is comprised of
approximately 1,680 acres of fee land, about 2,013 acres of SITLA Leases and
approximately 1,942 acres of BLM land covered by the unpatented claims in San
Juan County, Utah and San Miguel County, Colorado. Unpatented mining claims
expire annually, but are subject to indefinite annual renewal by filing
appropriate documents with federal and local authorities, and paying the fees
that total approximately $150 per claim.

Most of the project (the private leases and SITLA Leases, plus
44 of the unpatented claims) is located in San Juan County, Utah and the other
50 unpatented claims are located in San Miguel County, Colorado. All of the
property, except one private lease, is held by CPP. CPP was formerly a 50:50
joint venture between subsidiaries of Energy Fuels (EFRC) and Aldershot
(Lynx-Royal). On October 1, 2012, Energy Fuels acquired all of Aldershots
interest in CPP, and is now the sole owner of CPP. The other private lease is
held solely by EFRC. Therefore, the Company now owns and controls the entire
Sage Plain Project.

The two historic mines have been idle for about 20 years. Both mines were operated in the 1970s to early 1980s by Atlas. The Calliham Mine was acquired by Umetco in 1988 and operated briefly in 1990-1991. Both mines ceased production due to
depressed uranium and vanadium prices.

The various parcels of the project were acquired in stages. Energy Fuels was the successful bidder on two SITLA Leases in 2007. A third SITLA Lease was awarded to the Company in March 2011. These were subsequently assigned to CPP. CPP purchased 94
claims and another SITLA Lease from Uranium One Inc. in November 2010. Energy Fuels purchased a lease on the private Calliham parcel in February 2011 from Nuvemco, LLC and the Crain lease in July 2011 from UEC. Both of these leases were assigned to
CPP. The final acquisition in the project area, the Skidmore lease covering land owned by J.H. Ranch, Inc., was acquired in October 2011 from a private group that had an option to lease with J.H. Ranch. Lynx-Royal declined to participate in this
acquisition. Therefore, EFRC retained 100% ownership of the Skidmore lease. In May 2012, the Company acquired 80-acres from Umetco that contains the historic portal to the Calliham mine. On October 1, 2012, the Company acquired all of
Lynx-Royal’s interest in CPP. See “General Development of the Business – Recent Developments Since September 30, 2012”. As a result, the Company now owns 100% of CPP and the Sage Plain Project.

All claims, leases and other land holdings at the Sage Plain Project are current and in good standing. Below is a description of each parcel in the project:

Calliham Lease: Nuvemco LLC entered into a Mining Lease with members of the Calliham family on March 8, 2007. EFR purchased the lease outright from Nuvemco in February 2011. It was assigned to CPP. The term of the lease is perpetual, as long as the
lessee is in compliance with the terms of the lease. The lease requires an annual advanced royalty of $10,000 be paid to the lessor. The lease is paid for until March 8, 2012. The lessor reserves a production royalty at the rate of 5% of the
value of the uranium and 8% of the value of the vanadium based on the price received for the sale of ore. The lease covers the mineral rights on approximately 320 acres in the NW 1⁄4 NW 1⁄4 section 33 and SW 1⁄4, S 1⁄2 NW
1⁄4, and SW 1⁄4 NE 1⁄4, section 28, T32S, R26E, SLPM.

Crain Lease: Uranium Energy Corp. (“UEC”) entered into a Uranium and Mineral Lease with Nadine Crain on April 19, 2005 for all of section 27, T32S, R26E, SLPM, being 640 acre in area. UEC paid $25,000 for the primary term,
which was for five years. The lease was renewed at the expiration of the primary term for a second five year term by UEC paying $50/acre (in effect until April 19, 2015). The lessor reserves a production royalty of 6 1⁄4% of the net
proceeds received for uranium in ores and 5% for vanadium in raw, crude form before any processing or beneficiation. Energy Fuels purchased the lease from UEC on July 27, 2011 and it was assigned to CPP. CPP will pay UEC an overriding royalty of 4%
on the gross proceeds for uranium and vanadium produced from the property after the first 225,000 lbs. of U3O8 is produced.

Skidmore Lease: A privately held corporation, Nuclear Energy Corporation, LLC (“NUECO”), secured an option to lease several mineral lands in the district from J.H. Ranch, Inc. (“JHRI”) in March 2011. On the 10th
of October 2011, NUECO entered into a mining lease with JHRI covering surface and mineral rights in the E 1⁄2 section 29, SE 1⁄4 SW 1⁄4 and SW 1⁄4 SE 1⁄4 section 21, NE 1⁄4 NW 1⁄4, N 1⁄2 NE 1⁄4, SE
1⁄4 NE 1⁄4, and N 1⁄2 SE 1⁄4 section 28, T32S, R26E, SLPM. The lease also covers surface rights in the SW 1⁄4 SW 1⁄4 section 21 and NW 1⁄4 NW 1⁄4 section 28, T32S, R26E where the minerals are owned by the
federal government. Energy Fuels entered into an agreement with NUECO to purchase the lease on this portion of the JHRI property (referred to as Skidmore) adjacent to the Calliham property on October 7, 2011. Subsequently, the lease was assigned to
EFR on October 13, 2011. The primary term of the lease is for 20 years and is renewable. EFR will make payments allocated as 75% advanced royalties and 25 % rental that increase over time, varying from $125,000 in October 2011, $150,000 on
the first anniversary, $200,000 on the second anniversary, and $250,000 on the third and fourth anniversaries. Payments will
then fall to $10/acre/year. A production royalty will be due JHRI at 12.5% of the fair market value of crude ore. JHRI is also entitled to a small wheeling fee (toll) for any ore produced from any of the other leases that crosses the Skidmore
property in the underground mine haulage drifts. This lease is not part of CPP.

Sage et al. Claims: The 94 claims were staked in accordance with state and federal rules in November 2004 through May 2005, as the price of uranium was beginning to increase, by a private individual, Jim C. Butt. Butt leased the claims to Plateau
Resources Limited, Inc. in June 2005. Butt then sold the claims (terminating the lease) to Plateau Resources in March 2006, retaining a royalty of 2.5% . The claim ownership passed to Uranium One Exploration USA, Inc. in April 2007. CPP bought the
claims and a Utah State lease as a single transaction from Uranium One on November 22, 2010. Besides the annual BLM claim maintenance fee ($140) and annual county recording fees ($10), the royalty in favor of Jim Butt is the only encumbrance
on the claims. There are 40 Sage claims in sections 28, 33, 34, and 35, T32S, R26E, SLPM, San Juan County, Utah. In San Miguel County, Colorado there are 13 Red Ant claims, 15 Bear claims, 4 Black Spider claims, 8 Governor claims, and 10 Refund
claims (50 total) in sections 25 and 26, T43N, R20W and sections 19, 29, 30, 31, and 32 T43N, R19W, NMPM. The claims are all on BLM land with the land in Utah managed by the Monticello Field Office and the land in Colorado managed by the Dolores
Field Office. All federal and county claim fees are paid through August 31, 2014.  All unpatented mining claims expire annually.  However, they are renewable indefinitely for successive one year periods.

SITLA Leases ML-51145, 51146, and 51963: Energy Fuels acquired these three mineral leases from the State of Utah through normal offerings via sealed bids, the first two in November 2007 and the third in February 2011. They cover the SE 1⁄4
section 16, all of section 32, and the N 1⁄2 and SW 1⁄4 of section 16, respectively, in T32S, R26E, SLPM. No data from past exploration has been located. These parcels were acquired because of their location near the Calliham Mine and the
farther north Silver Bell and Wilson Mines. The lack of data precludes estimating any mineral resources for these parcels, but they are good exploration targets with high potential of discovering mineral resources with drilling. The annual cost to
hold these combined leases is presently $1,640. SITLA leases carry a production royalty on the gross value of ore, f.o.b. the mine at a basis of 8% on the uranium and 4% on the vanadium.

SITLA Lease ML-49301:  This lease was purchased by CPP along with the Sage et al. claims from Uranium One in November 2010. It covers all of section 16 (640 acre) and the fractional section 2 (93 acres), T33S, R26E, SLPM. Historic drill data are in
the Company’s position for this lease. Like the other SITLA leases it carries a production royalty on the gross value of ore, f.o.b. the mine, at a basis of 8% on the uranium and 4% on the vanadium. The lease was initially granted to Jim C.
Butt in March 2004. Butt then assigned the lease to Plateau Resources in July 2006, retaining a royalty to Butt of 1.0% . Subsequently, the lease passed to Uranium One Exploration USA, Inc in April 2007. The additional 1.0% royalty to Butt is Energy
Fuels’ obligation when production begins from this parcel.

There are two historic uranium-vanadium mines within the project area, the Calliham Mine which accesses the three private leases, and the Sage Mine which produced from the claims. The Calliham Mine has been totally reclaimed. Because the portal
closure consisted of back-filling for a short distance, it can easily be reopened and rehabilitated. The portal and reclaimed waste rock pile are located on private land that is not part of the Calliham lease. Energy Fuels acquired this land from
Umetco Minerals in 2012. The Sage Mine has an old permit through the State of Utah Division of Oil, Gas, and Mining (DOGM) still in effect, but has been inactive for about 20 years. Therefore, the permit will require an update before work can
resume. It has not been reclaimed, but a large dirt pile was used to cover the portal to prevent access. Both mines are partially flooded, but can be dewatered once permits are obtained. Historic data indicate neither mine encountered enough water
to be problematic when operating. See sections 6, 16, 18,
and 20 of the Sage Plain Technical Report for more detail on the history of the mines, the future plans for rehabilitation, development, and production, and the current permitting process.

Accessibility, Climate, Local Resources, Infrastructure, and Physiology

The Sage Plain Project can be accessed from the north, south, and east on paved, all-weather roads. The nearest towns with stores, restaurants, lodging and small industrial supply retailers are Monticello, Utah, 26 road miles to the south and west,
and Dove Creek, Colorado, 20 road miles to the southeast. U.S. Highway 491 connects Monticello, Utah to Dove Creek and Cortez, Colorado. There are two routes north from this highway to the project. From the highways, access to the Sage Plain Project
is from maintained county roads. The region has a long history of mining, ranching, farming, and oil and gas production. Therefore, even though the regional towns are small, they have adequate services and supplies to support a mineral project like
the Sage Plain Project.

The area is semi-arid. Meteorological data from the Northdale, Colorado station 10-miles south of the Sage Plain Project, show a recent 30-year normal mean temperature of 46 degrees F (range 31 to 61 degrees F).  The mean annual precipitation for
the same 30 years has been 12.26 inches.  Year-round operations may occur at the Sage Plain Project. All elevations within four miles of the Sage Plain Project property support moderate growths of sage and rabbit brush along with other brush, forbs,
cactus, yucca and grasses. There are localized stands of juniper and piñon pine in the rocky soils and many patches of scrub oak where it has never been cleared.

The region has a long history of mining, ranching, farming, and oil and gas production. Therefore, even though the regional towns are small, they have adequate services and supplies to support a project the size of the proposed Calliham and Sage
Mines. Energy Fuels expects to be be able to hire much of its mine labor from within the region. The regional grid of electrical transmission and distribution lines simultaneously supported the mines at the Sage Plain Project area plus the large
Deremo Mine operated by Umetco Minerals, 2 miles to the southeast, and the Silver Bell and Wilson Mines, 1 1⁄2 miles to the north.

The region of the Sage Plain Project is characterized by a relatively flat plain that is drained by three major regional rivers. Most of the private land is gently sloping, cut by small ephemeral streams that are tributary to Summit Canyon. The
unpatented claims are located in the head of Summit Canyon and along the benches on the south side of that canyon easterly to its confluence with Bishop Canyon. The land south of Summit Canyon, including SITLA Lease ML-49301, drains to Coal Bed
Canyon. The flatter part of the project sets at elevations ranging from 6,870 feet at the south edge of ML-49301 to 7,165 on the Crain lease.  The claims along Summit and Bishop Canyons cover much steeper terrain with elevations ranging from 6,500
feet to 7,380 feet.

The Company believes it has sufficient surface rights for contemplated mining operations, including waste disposal areas. No mineral processing is expected to occur on the property. Therefore, no land is required for tailings storage, heap leach
pads, or processing plants.

History

The uranium-vanadium deposits of the region were discovered in
the Morrison Formation 32 miles north of the Sage Plain Project in Roc Creek
Canyon, Montrose County, Colorado in 1881. The first economic shipments of ore
were in 1898. The carnotite deposits in the Salt Wash Member of the Morrison
Formation along the Dolores River canyon and Summit Canyon near Slick Rock,
Colorado were discovered around 1900, about 10 miles north of Sage Plain. Most
of this early production focused on extracting uranium-vanadium concentrates and
radium.

There was little activity in the region until the demand for
vanadium increased in the mid-1930s. Shattuck Chemical Company built a mill at
Slick Rock in 1931 and International Vanadium Corporation built a mill in Dry
Valley. Ore is estimated to have averaged about 0.15% U3O8 and 1.34% V2O5. North
Continent Mines Company bought the Slick Rock mill and enlarged it in 1934 and
operated it until 1943. In the early 1940s, the federal government formed the
Metals Reserve Company to facilitate vanadium production. As a result, many new
mines opened in the Salt Wash formation and more mills were built, including one
at Monticello, Utah. Almost all of the uranium in the ore went to the tails at
mills until 1943 when uranium became the focus. More deposits were found in the
Salt Wash and mines remained open into the 1950s and early 1960s in the Sick
Rock and Dry Valley districts near Sage Plain. Union Carbide built an upgrading
mill at Slick Rock in 1956 and operated it until 1970. Between 1948 and 1977,
the Slick Rock district produced over 4.1 million tons of ore at grades that
averaged 0.25% U3O8 and 1.8% V2O5.

The two mines located on the Sage Plain Project were operated
in the 1970s to early 1980s by Atlas. The Calliham mine was explored in the
early 1970s by Hecla. The Crain lease to the east of the Calliham mine was
explored by Truchas and later in the 1970s by Pioneer Uravan. The Calliham
lease was acquired by Atlas and went into production in March 1976. Atlas
departed the uranium business in the mid-1980s. The Calliham mine was acquired
by Umetco in 1988 and operated briefly in 1990-1991 during a spike in vanadium
prices. Umetco was also operating the Silver Bell and Wilson mines nearby.
During Umetcos tenure, the Calliham mine produced 13,300 tons of ore averaging
0.21% U3O8 and 1.29% V2O5. This ore was milled at the White Mesa Mill in
Blanding, Utah (now owned by the Company). The Sage mine reportedly produced
3,000 tons of ore in 1990, but historic production numbers are not known at this
time.

Geological Setting

The Sage Plain district, also referred to as the Egnar district
or Summit Point district, is a portion of the greater Slick Rock district. It is
the southwest continuation into Utah of the Uravan Mineral Belt. Here, the host
sandstones of the Salt Wash Member of the Jurassic-aged Morrison Formation are
not exposed. They are covered by Cretaceous-aged sediments or the upper Morrison
Formations Brushy Basin Member. Therefore, discovery of economic deposits here
lagged many years behind the production from the same host rocks elsewhere in
the Slick Rock district a few miles to the northeast in Colorado. At Slick Rock,
mining and milling of radium-uranium-vanadium ores has occurred since 1901. This
part of the Uravan Mineral Belt has a significantly higher ratio of V2O5:U3O8 in
the ore than the deposits farther north.

Exploration

Outcrops within a few miles of the Sage Plain Project were
explored by prospectors in the early 20th century for their radium and vanadium
content. Uranium exploration began in the mid-1940s. Exploration by drilling
progressed to the mesa tops as drilling equipment improved in the 1950s and
1960s. The deposits in the Sage Plain area were found and developed by other
operators in the late 1960s and early 1970s. The area around the Companys Sage Plain
Project was extensively drilled in the 1970s and early 1980s.

During the operation of the underground mines, extensive
stoping occurred. In addition, extensive long-hole drilling occurred. Much of
the Mineral Resource in the Calliham mine was identified in this manner. In
2011, CPP (now a wholly-owned subsidiary of the Company) conducted a 17 hole
rotary drill program (~11,300 feet). Seven holes were drilled at the Sage mine
to confirm historic map data and explore for a possible east-west channel. Two
holes testing the historically defined mineralized body confirmed the historic
map data and one exploration hole intersected high-grade mineralization between
the mine workings and the western mineralized body. Ten holes were drilled
across the Calliham mine properties to confirm historic map data and expand
known mineralization. Eight out of the ten holes had significant mineralization,
indicating historic map data to be correct.

Mineralization

The uranium- and vanadium-bearing minerals in the Salt Wash
Member of the Morrison Formation occur as fine-grained coatings on the detrital
grains, they fill pore spaces between the sand grains, and they replace some
carbonaceous material and detrital quartz and feldspar grains. The primary
uranium mineral is uraninite (pitchblende) (UO2) with minor amounts of coffinite
(USiO4OH). Montroseite (VOOH) is the primary vanadium mineral, along with
vanadium clays and hydromica. Traces of metallic sulfides occur. In outcrops and
shallow oxidized areas of older mines in the surrounding areas, the minerals now
exposed are the calcium and potassium uranyl vanadates, tyuyamunite, and
carnotite. Minerals from several oxidation stages can be seen, including
corvusite, rauvite and pascoite. The Sage and Calliham mines have been standing
full of water for at least ten years, so no direct observations have been made
of the mine workings. Some stoping areas in the Sage and Calliham mines, as well
as the nearby Deremo mine to the east and Silver Bell and Wilson mines to the
north, are well over 1,400 feet long and several hundred feet wide. Individual
mineralized beds can vary in thickness from several inches to over ten feet.

Drilling

Most of the drilling on the Calliham and Sage mine properties
was performed by previous operators, including Hecla, Atlas, Pioneer Uravan, and
Truchas. There have been approximately 313 holes drilled on the Calliham lease,
300 on the Crain lease, 487 on the Skidmore lease, and 199 on the claims near
the Sage mine. The Company has in its possession several maps showing the
locations of holes on and surrounding the Sage Plain Project. The Company
acquired the gamma and lithologic logs for these holes when it acquired the US
Mining Division. The Atlas, Pioneer Uravan and Umetco drill maps and mine maps
with longhole data are deemed to be accurate.

The Company has conducted two drilling projects, one on the
Sage mine claims and one across the three Calliham mine leases to verify some of
the historic map data. Seven holes were drilled by CPP (now wholly-owned by the
Company) on the Sage mine claims in October 2011 totaling 4,873 feet. The
drilling was successful in meeting the objectives of confirming the accuracy of
the historical data and verifying a historically defined mineral body. One hole
intercepted 2.0 feet of 0.407% eU3O8. Another hole intercepted mineralization
greater than 1.0 foot of 0.16% eU3O8.

Ten holes were drilled by CPP across the three Calliham leases
in December 2011 totaling 6,465 feet. This drilling was also successful in
meeting the objectives of confirming the accuracy of the historic data and
expanding known mineralized areas. Four holes intercepted mineralization greater
than 1.0 foot of 0.20% eU3O8 and four other holes intercepted mineralization
greater than 1.0 foot of 0.10% eU3O8.

All holes drilled by CPP were probed using a natural gamma tool
along with resistivity and spontaneous potential logs when the holes contained
water. An induction tool was used in holes that were dry. All holes were also
logged with a deviation tool. Even though the digitally recorded data displays
estimated U3O8 content, the gamma logs were interpreted and mineralization
calculated using the proven AEC method. It is believed that previous operators
also used this method, or a close variant of it.

Sampling and Analysis

Energy Fuels has not conducted widespread and definitive
sampling on the Sage Plain Project. Previous underground mining activity, which
resulted in development drifting and production at the two mines, will not be
available for sampling until the mines are dewatered and the declines
rehabilitated. The estimations of resource have relied on documentation from
earlier operators and the 2011 drilling program. CPP employed a conventional
combination of rotary drilling, geologic logging, and downhole electric and
radiometric logging in its field program.

Mineral Resource Estimate

Historic drilling from the surface by previous operators
(including Hecla, Atlas, Truchas, Pioneer Uravan, and Umetco), long-hole
drilling within the underground mines, and verification and fill-in exploration
drilling in 2011 by CPP suggest remaining Measured and Indicated Mineral
Resources at the Sage Plain Project of approximately 2,833,795 lbs. U3O8 and
17,829,289 lbs. V2O5. This is contained in roughly 642,971 tons of material at
an in-place grade of 0.220% U3O8 and 1.39% V2O5. Additionally, Inferred Mineral
Resources are estimated at 49,136 tons with an in-place grade of 0.184% U3O8 and
1.89% V2O5 (181,275 lbs. U3O8 and 1,854,034 lbs. V2O5). This resource estimate
for the Sage Plain Project is divided into the particular leases and claims for
reporting in the Sage Plain Technical Report. The resources of the Calliham,
Crain, and Skidmore leases are accessible through the Calliham Mine. The Sage
Mine will be used to access the resources on the Sage claims. Mineral resources
on the other claims and those on the SITLA Leases will likely require new mine
entries to be exploited.

As noted above, the Company acquired 100% of CPP (and the Sage
Plain Project) effective October 1, 2012. However, the mineral resource estimate
was prepared prior to the Companys acquisition. Therefore, the resources are
broken down according to the ownership interest of the former partners as of
September 30, 2012. As of October 1, 2012, Energy Fuels owned all of the
Measured and Indicated Mineral Resources listed below, being 642,971 tons
containing 2,833,795 lbs. U3O8 (0.22% eU3O8) and 17,829,289 lbs. V2O5 (1.39%V
2O5). As of October 1, 2012, Energy Fuels owned all of the Inferred Mineral
Resource, being 49,136 tons containing 181,276 lbs. U3O8 (0.184% eU3O8) and
1,854,034 lbs. V2O5 (1.89% V2O5).

Mineral resource estimates have been calculated by a modified
polygonal method. The older drilling was often on 50-150 foot spacing in the
well mineralized parts of the Sage Mine area. For the well mineralized parts of
the Calliham and Skidmore leases, the drill hole spacing is usually 75-200 feet.
On the Crain lease the drilling is usually 100-200 feet spacing in the
mineralized areas, as is the case on ML-49301. Elsewhere on all properties
drilling was done on wide-spacing initially (500-1,000 feet). Where favorable
criteria were found, the operators tightened the pattern or did offsets at
100-200 feet resulting in several clusters of closer-spaced holes scattered
around the entire property. The 2011 drilling program on the Sage Plain Project
properties partially consisted of offset holes on spacings of 30-60 feet from
historic holes. There were a few exploration holes, especially on the Sage Mine
claims, in areas where historic drill holes are several hundred feet apart.

Where hole-spacing is closer than 100 feet, a perpendicular
bisector method was used to create the polygons. Where hole spacing is greater
than 100 feet, the holes used for mineral resource estimations are
shown on the maps as squares of 100’ X 100’ (10,000 square feet). However, to remain conservative, a 50-foot influence distance centered on the hole has been used. Therefore, all polygons that exceed an area equal to a 50-foot radius
circle (7,854 square feet) have been reduced to that area for tonnage calculations in the Mineral Resource blocks. Even though mineralization in these deposits can be highly variable over short distances in the deposit, past mining experience has
shown that there is enough continuity over stoping distances or even a few contiguous resource polygons that production matches resource estimates quite well. At locations where drifting or stoping has removed portions of polygons, there have been
appropriate reductions to the resources assigned those polygons. Next to mine workings, polygons based on holes drilled from the surface often overlap with polygons drawn on the underground longholes. Where this occurs, the surface hole polygon was
trimmed and the longhole data used for the smaller polygon(s) adjacent to the mine. The distance of influence used for longhole intercepts never exceeds 40 feet from the hole.

158

---

In some areas there are two or more mineralized horizons separated by more than two feet of waste. Where this occurs, there are two or more polygons drawn for the same hole. These may be of the same shape or different overlapping shapes, depending
on the mineralization in the nearest neighboring holes used to define the polygons. The polygons that are adjacent to mine workings or are within a few hundred feet of the workings (so that they can be developed when the mines are reopened) and are
clustered with other polygons are considered Measured Mineral Resources. For the in situ resource estimate, the thickness and grade assigned to each polygon equals that of the intercepts recorded in the center hole of the polygon. A tonnage factor
of 15 cubic feet per ton is used for Salt Wash deposits.

Indicated Mineral Resource blocks were drawn where mineralization correlates well and similar geological conditions are believed to be continuous between drill holes that are over 100 feet apart. The Indicated Mineral Resource blocks are individual
holes or groups of holes that are separated from mine workings by a few hundred feet more than the Measured Mineral Resource blocks. The grade and thickness for the indicated blocks are weighted averages of the particular drill holes’
intercepts that define each block.

Indicated Mineral Resource blocks are drawn where mineralization correlates well and similar geological conditions are believed to be continuous between drill holes that are over 100 feet apart. The Indicated Mineral Resource blocks are individual
holes or groups of holes that are separated from mine workings by a few hundred feet more than the Measured Mineral Resource blocks. The grade and thickness for the indicated blocks are weighted averages of the particular drill holes’
intercepts that define each block.

Inferred Mineral Resource blocks are partially drilling-confirmed, geologically favorable areas where other deposits could occur in the defined channels. Mineral trends often follow the directions of the sandstone channels. The Sage Plain Project
has three areas where the mineralization found in wide-spaced holes suggests Inferred Mineral Resources may exist.

Sandstone thickness, the gray color, and pyrite and carbon contents of sandstones, along with gray or green interbedded or underlying mudstone, indicate areas of sandstones that are favorable for containing uranium-vanadium mineralization. These
conditions allow geological definition of Inferred Mineral Resources, in conjunction with some drilling data, and Exploration Targets where no drilling data are available or are too far away to be considered relevant to defining Inferred Resources.
Mining assumptions were used in determining a cutoff grade for the resource estimates. The minimum mining thickness for this type of sandstone uranium deposit is considered to be 2 feet. Uranium grades of 0.00% are used to dilute any intercept less
than 1 foot to meet the 2 feet minimum. Mining dilution is considered to be 1 foot of waste for mineralized thicknesses greater than 1 foot, but less than 6.0 feet or an appropriate fraction of a foot (if the intercept is greater than 6 feet) up to
7.0 feet. A resuing or splitshooting mining approach will be followed to minimize dilution when extracting thin zones. The eventual stope height will be 7 feet or greater to allow the
mine to advance. At the time of mining, the waste above or below the mineralized
horizon, or waste separating two mineralized streaks, is blasted separately.
This waste layer usually must be more than two feet thick to be considered worth
shooting separately. Depending on the waste-ore configuration in the face, the
mineralized zone may be blasted before the waste or vice-versa. For the Calliham
and Sage Mines, 7.0 feet is the assumed minimum stope height. Mineralized
intercepts greater than 7.0 feet are not diluted for resource calculations. It
is conservative to use waste at zero grade for the dilution, because there is
often lower-grade material adjacent to the target mineralized zones.

159

---

Vanadium assays are available for some of the drill holes.
Where no data exist on vanadium content, the intercept is assigned a value based
on the historical Umetco Minerals resource estimate for the various properties
(Umetco, 1991). These V2O5:U3O8 ratios range from 4.75:1 up to 8.95:1. The
combined properties of the Calliham Mine and the Sage Mine average 6.25:1. This
is the ratio used for resource estimation where no data occurs. This ratio
cannot be guaranteed and must be used only as a historical estimator for
vanadium mineralization potential.

A cutoff of 0.07% U3O8, after the dilution has been applied, is
used in all resource estimates for the Sage Plain Project properties that are
based on historic or current drilling results. This cutoff is somewhat
subjective and was chosen based on experience of Energy Fuels staff and on the
basis of the lowest grade intercepts that are likely to be mined based on a
tentative mine plan and location of such intercepts in or adjacent to
development entries that will be mined regardless of the grade of involved
mineralized sandstone. Assumptions involved in use of this cutoff are as
follows:

| | 1) | Development entries will be made to access Indicated and
      Measured Mineral Resources of sufficient size to warrant mining to their
      locations and room-and pillar mining of the resources. Such entries will
      follow the historic random pattern of mining areas that is driven by the
      localized nature of areas of mineralization.                                                                
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| | 2) | Entries can and will intercept some lower grade material
      that would not necessarily be economically mineable as standalone
      resources.                                                                                                                                                                                                                                                                       
| | 3) | Vanadium grade, in combination with uranium grade, can be
      high enough to warrant mining a resource area even if the uranium contents
      in all holes in that area would not be sufficient to make the
      mineralization mineable through uranium content alone.                                                                                                                                             
| | 4) | The thickness of the drill intercept in mineralized
      material makes some areas attractive because of available volume of
      mineralization even when relatively low grade for uranium.                                                                                                                                                                                                                          
| | 5) | Any mineralized material below the cutoff grade that is
      mined during development or room-and- pillar extraction will be considered
      waste regardless of contained uranium and vanadium values.                                                                                                                                                                                                               
| | 6) | Indicated or Measured Mineral Resources may still prove
      to be uneconomic to mine upon performance of a full feasibility analysis
      or due to economic or mining conditions at the time mining proceeds
      towards such resource areas. The inverse also could be true. A substantial
      increase in the price of uranium or vanadium could result in a lower
      cutoff being in effect during mining.
| | 7) | Minimum mining thickness is 2 feet using the
      split-shooting or resuing mining methods.

Permitting

The Sage Plain Project contains two historic producing mines,
and by the Fall of 2011, Energy Fuels had assembled sufficient contiguous
historical resource acreage to begin the process of obtaining permits for
both the Calliham and Sage mines. The Calliham Mine will require permits from UDOGM, UWQD, and UAQD for mining/reclamation, water treatment and discharge, and air emissions, respectively. The project is located on private land and will not require
any permits with federal agencies. The Sage Mine has an approved Small Mine NOI with UDOGM and exploration permit with the BLM. This mine will require a permit amendment with UDOGM to expand the mine plus permits for water discharge and air
emissions. A PO will also need to be submitted to the BLM and an EA completed for the project. Much of the baseline work needed for the permit applications was completed in 2012, including biological and cultural resource surveys, groundwater
monitoring, and geotechnical analysis for surface installations. Permitting work on these two mines was temporarily suspended in September 2012 because the environmental staff needed to focus on permitting several other mines that had recently been
acquired in the Denison acquisition. Energy Fuels anticipates that the permitting work on the mines will resume later in 2014.

Contemplated Exploration or Development Activities

No current exploration or development activities are planned for the Sage Plain Project at this time.

Copper King Gold/Copper Project

Unless otherwise stated, the following description of the
Copper King Project is derived from the technical report dated August 24, 2012
entitled, Technical Report on the Copper King Project prepared by Paul Tietz,
C.P.G. and Neil Prenn, P. Eng. of Mine Development Associates (MDA) in
accordance with NI 43-101 (the Copper King Technical Report). Each
author of the Copper King Technical Report is a qualified person and
independent of the Company within the meaning of NI 43-101. A copy of the
Copper King Technical Report is available under Strathmores profile on SEDAR at
www.sedar.com.

Location and Ownership

The Copper King project is located in southeastern Wyoming,
approximately 32km west of the city of Cheyenne, on the southeastern margin of
the Laramie Range. The property covers about five square kilometers that include
the S1⁄2 Section 25, NE1⁄4 Section 35, and all of Section 36, T.14N., R.70W.

Strathmore acquired its interest in the Copper King Project in
May 2012 through an agreement to acquire all of the issued and outstanding
shares of Saratoga Gold Company Ltd. (Saratoga). The property is held
through two State of Wyoming Metallic and Non-Metallic Rocks and Minerals Mining
Leases (the Copper King Leases) that extend through February 1, 2023
and February 1, 2024. The current total rental payments are $2,240 annually with
a production royalty ranging from 5 to 10% once production has commenced,
although the Wyoming State Board of Land Commissioners has the authority to
reduce that percentage. Both Copper King Leases can be renewed for successive
10-year terms. An easement agreement providing access has been negotiated with
Ferguson Ranch Inc. on the S1⁄2 Section 25, T.14N., R.70W., and also the W1⁄2
Section 30, T.14N., R.69W. Prior to mining development, a surface impact payment
would have to be negotiated with the lessee, which annual payment would then be
split between the State of Wyoming and the surface lessee based on a sliding
scale.



There are no outstanding environmental liabilities to which the
project is subject.

Accessibility, Climate, Local Resources, and Infrastructure

The Copper King Project is located in Laramie County, Wyoming, about 32km west of Cheyenne, Wyoming. Access to within 1.5km of the property is provided by paved and maintained gravel roads, although driving conditions might be difficult in the
winter. The surface of S1⁄2 Section 25 and NE1⁄4 Section 35 is privately owned. An easement agreement providing access has been negotiated with Ferguson Ranch Inc. on the S1⁄2 Section 25, T.14N., R.70W., and also the W1⁄2 Section
30, T.14N., R.69W. Annual payments on the easement agreement are $10,000. The agreement has been renewed for the current year.

Annual precipitation averages 43cm, of which the majority falls as winter snows, which may hamper transportation for short periods after heavy snowfalls. Otherwise, the project should be able to sustain year-round operations. Summer temperatures are
mild; subfreezing temperatures are common during the winter. Overall, temperatures range from -37° C in the winter to 32° C in the summer.

Lodging, supplies, and labor are available in Cheyenne, a city of about 59,500 (2010 census). A paved road is within 8km that provides direct access into Cheyenne, which is served by Interstates 80 and 25 along with a full-service airport. The Union
Pacific main line runs through Cheyenne, and a smaller trunk line passes by the property about 13km to the northeast. Interstate 80 and the main line of the Union Pacific Railroad lie about 6km to the south of the Copper King property, although
there is no direct maintained access to this portion of the transportation corridor.

High-voltage power lines are located about 2.4km from the project, and local power lines serve the scattered residences along Crystal Lake Road.

There is ample ground east and south of the Copper King project area for mining infrastructure with a large flat area south of the mineralized area and still on the State section.

There are no significant water sources on the property. South Crow Creek and Middle Crow Creek, both perennial streams, lie 1.6km to the south and north. A large nearby reservoir, Crystal Lake Reservoir, lies 1.2km to the northwest within Curt Gowdy
State Park. Previous site reports (Nevin, 1973; Mountain Lake Resources, 1997) indicate that the city, specifically the Cheyenne Board of Utilities, would be receptive to a proposal to sell water for mine use from this and other nearby reservoirs.
Were to production commence, these permissions would need to be renewed and verified.

Groundwater is <46m deep at the project site, and deep wells, or the dewatering of a future open-pit, could serve as an adequate water source for the mine. No hydrological studies have been completed to date on the property.

There is some low-density residential development east and west of the Copper King Project. From about six to 11km east of the Copper King mine there are 30 to 40 scattered homes. About 1.6km west of the mine are about five to eight scattered homes
with 15 to 20 homes along Crystal Lake Road 4km west of the mine. The Ferguson Ranch is a working ranch located about four km northeast of Copper King mine.

The Company believes that the project has sufficient surface rights to engage in all contemplated mining operations, including potential waste disposal areas. No milling is contemplated on the site, therefore no land is required for tailings, heap
leach pads or processing sites.

History

Limited exploration and mining were conducted on the Copper King property in the late 1880s and early 1900s. Approximately 272 tonnes of material were reported to have been produced from a now inaccessible 48m-deep shaft with two levels of
cross-cuts. A few small adits and prospect pits with no significant production are scattered throughout the property.

Since 1938, at least nine historic (pre-Strathmore) drilling campaigns by at least seven companies plus the U. S. Bureau of Mines (“USBM”) have been conducted at the Copper King Project. The current project database contains 91
drill holes totaling 11,429m that were drilled before Saratoga acquired the property.

The most recent drilling on the property was conducted by Saratoga, who completed a drill exploration program on the property in 2007 and 2008. Thirty-five diamond core drill holes were completed for a total of 7,762m. The focus of the work was to
confirm and potentially expand the mineralized body outlined in the previous drill campaigns, increase the geologic and geochemical database leading to the creation of the current geologic model and resource estimate, and to provide material for
further metallurgical testing.

Neither Strathmore nor Energy Fuels has conducted exploration on the Copper King Project to date.

Geologic Setting

The Silver Crown mining district, within which the Copper King project is located, is underlain by Proterozoic rocks that make up the southern end of the Precambrian core of the Laramie Range. Metavolcanic and metasedimentary rocks of
amphibolite-grade metamorphism are intruded by the approximately 1.4 billion year old Sherman Granite and related felsic rocks. Within the project area, foliated granodiorite is intruded by aplitic quartz monzonite dikes, thin mafic dikes, and
younger pegmatite dikes. Shear zones with cataclastic foliation striking N60°E to N60°W are found in the southern part of the Silver Crown district, including at Copper King. Copper and gold mineralization at Copper King occurs primarily in
unfoliated to mylonitic granodiorite. The granodiorite typically shows potassium enrichment, particularly near contacts with quartz monzonite. At Copper King, mineralization is associated with a N60°W-trending shear zone.

The Copper King deposit is thought by some to be a Proterozoic porphyry gold-copper deposit (Hausel, 1992, 1997; Carson, 1998), and is included in a list of undeveloped porphyry copper deposits by Long (1995). Others (Klein, 1974) categorized the
Copper King deposit as a structurally controlled base and precious metal deposit in a Precambrian shear zone.

Exploration

Limited exploration and mining were conducted on the Copper King property in the late 1880s and early 1900s. Approximately 272 tonnes of material were reported to have been produced from a now inaccessible 48m-deep shaft with two levels of
cross-cuts. A few small adits and prospect pits with no significant production are scattered throughout the property.

Since 1938, at least nine historic (pre-Strathmore) drilling campaigns by at least seven companies plus the U. S. Bureau of Mines (“USBM”) have been conducted at Copper King. The current project database contains 91 drill holes
totaling 11,429m that were drilled before Saratoga acquired the property. There are only limited, third-party references to four historic holes, and therefore these four holes are not included in the database. Also, one of the core holes re-entered
and then deepened an earlier hole and so is considered just one hole, with one surface collar location,
within the current database. All but six of the drill holes are within the
current resource area.

MDA has very little information on sampling or analytical
procedures for most of the pre-Saratoga drilling campaigns. With the exception
of limited check assaying, there is no evidence of quality assurance/quality
control measures having been taken by all but the most recent previous
operators.

However, drilling by five different operators since 1970 has
generally confirmed the mineralization identified by the drilling of two
companies and the USBM prior to 1970, which lends confidence to the drilling
results.

Other work conducted at Copper King by previous companies has
included ground and aeromagnetic surveys as well as induced polarization
(IP) surveys along with geochemical sampling, geologic mapping, and a
number of metallurgical studies.

The most recent drilling on the property was by Saratoga, who
conducted a drill exploration program in 2007 and 2008. Saratoga completed 35
diamond core drill holes for a total of 7,762m. The focus of Saratogas work was
to confirm and potentially expand the mineralized body outlined in the previous
drill campaigns, increase the geologic and geochemical database leading to the
creation of the current geologic model and resource estimate, and to provide
material for further metallurgical testing.

The Company (including Strathmore) has conducted no exploration
on the Copper King project to date.

Mineralization

The Copper King deposit consists of a near-surface, central
core of high-grade (>1.71g Au/t) mineralization, 175m long, 50m wide, and
150m thick, associated with moderate to pervasive silicification and
near-vertical thin, sulfide-bearing quartz veins and stockwork. The high-grade
core is surrounded by a large envelope of low-grade disseminated mineralization,
760m long along its N60oW strike, up to 300m wide at the widest part,
and over 330m in thickness. The low-grade mineralization is open along strike,
both to the northwest and southeast, and also at depth, where historic core
holes have encountered mineralization to a depth of at least 305m. Gold and
copper mineralization within the lower-grade portion of the deposit is uniformly
consistent in tenor both along strike and at depth. Historic and Saratoga drill
holes have intercepted >250m of continuous gold and copper mineralization in
which over 90% of the individual gold assays range between 0.3g Au/t and 1g
Au/t. grade and copper values range between 0.1% Cu and 0.3% Cu.

Drilling

As of the effective date of the Copper King Technical Report,
120 drill holes totaling 18,105m occur within the Copper King deposit area and
are in the current database. The drill total includes 62 core holes totaling
11,276m (62% of total drill footage), 30 conventional rotary holes totaling
3,383m, 23 reverse circulation (RC) holes totaling 2,219m, and 5 holes
started with RC but finished with core that total 1,227m. Both vertical and
angle holes have been drilled, and the maximum vertical depth is 305m. All of
the drill holes were continually sampled down-hole with most of the historic
drilling on predominantly 1.5m or 3m intervals, while the Saratoga sampling was
predominantly at 1.5m intervals. All 120 drill holes, including collar location,
down-hole orientation, and analytical results, are in the current project
database. Limited data exist concerning drill procedures or collar surveys for
the drilling prior to that of Saratoga. Except for one pre-Saratoga core hole,
MDA has no evidence that any of the other holes drilled on the Copper King
property by previous operators were down-hole surveyed. All Saratoga drill-hole
collars were professionally surveyed, and all Saratoga holes have down-hole
survey data.

The Copper King drill-hole assay database contains 8,357 gold
assays and 8,225 copper assays. Sixty percent of the analytical data within the
current database are from the Saratoga drill program. MDA has validated the
majority of historic drill data using the previous operators internal
drill-hole location and assay records, not from first-party sources, which would
include original laboratory assay certificates.

The Saratoga data have been validated against original source
material, including collar survey files, original driller-recorded down-hole
survey data, and digital assay data direct from the laboratories. Saratogas
quality assurance/quality control measures included the use of standards and
blanks along with pulp duplicate and pulp-re-assay testing, the latter using a
second umpire laboratory.

The Company (including Strathmore) has conducted no drilling on
the property to date. Historic drilling on the property is summarized below.

Saratogas 2007 and 2008 drill results confirmed the high-grade
mineralization and also confirmed the presence of mineralization across the
length and breadth of the deposit. All of the 2007 and 2008 holes which were
cored were down-hole surveyed for deviation. Other data collected on many of the
holes in this program were core photography, RQD and core- recovery
measurements, geologic logging, and
sampling. Core recoveries averaged over 90% with many long intervals at over 95%. Some of the core was exposed to the weather, onsite, due to limited covered space.

Sampling and Analysis

To date, 120 drill holes totaling 18,105m occur within the Copper King deposit area and are in the current database. The drill total includes 62 core holes totaling 11,276m (62% of total drill footage), 30 conventional rotary holes totaling 3,383m,
23 reverse circulation (“RC”) holes totaling 2,219m, and 5 holes started with RC but finished with core that total 1,227m. Both vertical and angle holes have been drilled, and the maximum vertical depth is 305m. All of the drill holes
were continually sampled down-hole with most of the historic drilling on predominantly 1.5m or 3m intervals, while the Saratoga sampling was predominantly at 1.5m intervals. All 120 drill holes, including collar location, down-hole orientation, and
analytical results, are in the current project database.

The Copper King drill-hole assay database contains 8,357 gold assays and 8,225 copper assays. Sixty percent of the analytical data within the current database are from the Saratoga drill program. The Saratoga data have been validated against
original source material, including collar survey files, original driller-recorded down-hole survey data, and digital assay data direct from the laboratories. Saratoga’s quality assurance/quality control measures included the use of standards
and blanks along with pulp duplicate and pulp-re-assay testing, the latter using a second umpire laboratory.

Saratoga sampled the 2007 and 2008 drill core on approximate 1.5m intervals, although sample intervals did range from 0.3 to 3m as warranted by the geology. Due to the pervasive alteration and potential for mineralization observed throughout all
drill holes, the core was continuously sampled with no gaps in the sample sequence. The samples were collected principally by sawing the core in half, though some intervals, due either to the hardness of the rock or the unavailability of the saw,
were split with a hydraulic splitter. One half of the core was bagged and sent for assay, while the remaining half was placed back into the core box and put into storage. Energy Fuels maintains all remaining core from these programs in locked
storage.

The Saratoga core samples from the 2007 drill program were shipped to ALS Minerals (“ALS”, formerly called ALS Chemex) in Elko, Nevada for sample preparation and then on to the ALS facility in Sparks, Nevada, for analysis for gold
and a 33-element geochemical suite. Final results were received in December 2009. The ALS sample preparation and analysis methods requested by Saratoga were “AA23” for gold and “ME-ICP61” for the geochem suite. The detection
level for the analysis was 5 ppb Au, while the upper precision level was 10 ppm Au. Samples assaying over 10 ppm were re-assayed using a fire assay with gravimetric finish technique (ALS lab code “Au-GRA21”), which has an upper precision
level of 1,000 ppm Au. The “ME-ICP61” analytical geochem procedure consists of a four-acid digestion and analysis by inductively coupled plasma (“ICP”) followed by atomic emission spectroscopy (“AES”). The
reported range for copper values using this technique is between 1 and 10,000 ppm Cu. Samples with initial values over 10,000 ppm Cu were re-run using the same analytical techniques optimized for accuracy and precision at high concentrations (ALS
lab code “CU-OG62” with an upper precision of 40 percent Cu).

After completion of analyses and temporary storage at ALS, all of the pulps and selected coarse reject samples from mineralized intervals were retrieved by Saratoga and are currently in storage in Elko, Nevada. Energy Fuels continues to maintain all
remaining core rejects and sample pulps from these programs in locked storage, in Elko, NV.

Neither Strathmore nor Energy Fuels have done any drilling on the property to date.

Security of Samples

The drill crew, upon filling a core box, placed a wooden top over the core, and the box was secured using strapping tape. At the end of each drill shift, the core was transported by the drill crew into Cheyenne, WY, a distance of about 32km, and
placed in a locked commercial storage unit. The storage unit is located within a secure, gated facility. About once per week, the core were transported on a trailer to a logging and sampling facility in Casper, Wyoming, a distance of about 320km.
After being logged and sampled, the remaining half-core was placed in a locked storage unit within a secure, commercial storage facility in Casper.

All remaining 2007 core holes were transported 320km to Dubois, Wyoming, for storage and further core processing. Sampling was conducted within an open-sided ranch shed on private property owned by Norm Burmeister, an officer with Saratoga. The core
facility was within a fenced area. After sampling was complete, the core was transported to a commercial storage facility and stored on racks in a locked storage unit. These same procedures were used for the 2008 drilling.

The Saratoga core is currently stored in two facilities. The initial 11 drill holes from the 2007 campaign and the core from all eight holes of Saratoga’s 2008 drilling are in a secure storage facility in Cheyenne, Wyoming, along with
remaining unsampled core from Compass’s holes. Saratoga’s 16 remaining 2007 core holes are in a secure storage facility in Dubois, Wyoming.

At the time of their report, MDA was of the opinion that the sampling methods, security, and analytical procedures were adequate for mineral resource estimation.

Data Verification

Data verification undertaken by previous operators on the Copper King project is not documented in a manner that meets 43-101 standards. No quality assurance/quality control (“QA/QC”) measures were used on holes drilled prior to 1972,
and with the exception of the check assays, MDA was unable to verify that any additional QA/QC measures were taken in drill programs after 1972.

Saratoga’s QA/QC program implemented for the 2007 and 2008 drilling included analytical standards and blanks inserted into the drill-sample stream, duplicate assaying of selected coarse-reject samples by the primary assay laboratory, and
re-assaying of original pulps by an umpire laboratory.

MDA, in 2006 and 2007, collected six surface and 25 core samples for data verification purposes. Four of the core samples were from Compass’s 1994 drill program, while 21 were from selected intervals in Saratoga’s 2007 drilling.

Database Audit

There were virtually no original historic data available to MDA with which to audit the database. MDA did verify the drill-hole locations and values of those samples from ASARCO’s holes A-1 through A-5, Copper King’s holes C-6 through
C-11, and the USBM’s holes B-1 through B-3 by crosschecking values in the database with those reported in Soule (1955), but no original assay certificates were available for these or any other drill holes except Compass’s holes CCK-19
and the cored portion of CCK-24. MDA verified the assay values in the database for Compass’s holes CCK-19 and CCK-24 by crosschecking the values in the database with those shown on the assay certificates, and no errors were found. MDA verified
gold values for the best gold intercepts in the holes drilled by Henrietta by crosschecking assays included on geologic logs against values in the database. Only one error was found and corrected in the database.

168

---

MDA did find spreadsheets with assays said to be from Barringer
Labs for Mountain Lakes eight drill holes and entered those assays into the
database.

MDA compiled the drill-hole collar, survey, and assay data from
the 2007-2008 Saratoga drill programs directly from original sources. The
original collar survey data files and the down-hole survey drillers notebooks
were provided by Saratoga, while the assay data were digital data direct from
the laboratories. After compiling the data, the data were audited against the
original sources by randomly checking values and specifically checking down-hole
survey data that appeared anomalous. Six individual down-hole surveys were
removed from the database due either to uncertain depths or atypical azimuth
values. In all cases, the atypical azimuth values coincided with anomalously
high magnetic field readings.

Quality Assurance/Quality Control (QA/QC)

The check assay analyses have shown good agreement between the
ALS duplicate pulp analyses on the original ALS coarse rejects and also between
the ALS pulp re-assays of the original American Assay samples. No significant
biases or assay variability issues were found within these data. There are
concerns, primarily within the copper analyses, with the December 2009 American
Assay pulp duplicate and pulp re-assay check analyses. Further examination and
follow-up analytical work are warranted to determine the specific problem within
these data, though any resolution of these issues would not materially affect
the current resource model or stated resource.

In the context of the large bulk-tonnage nature of the deposit
and the consistency of gold and copper grades, both within and between drill
campaigns, it is not believed that the occasional failures observed in the
Saratoga standards create a significant concern in the estimation and
classification of the resource.

MDA collected six surface samples from within the footprint of
the historic resource, while an additional four samples were taken from three
Compass core holes that were in storage in Cheyenne, WY. The MDA samples were
kept in MDAs possession until they were delivered to ALS for analysis. The
samples were assayed for gold by standard fire assay/AA finish procedures, while
an additional suite of 27 elements was analyzed using a four-acid digestion and
AA analysis. The assay results from the 10 MDA samples, as shown in the
following table, confirmed the presence of significant gold and copper
mineralization within the Copper King project area.

Five of the surface samples assayed greater than 3.43g Au/t
with a high of 9.634g Au/t. Copper values were all 0.25% or greater with a high
of 1.3% . The samples were from both dump and outcrop collected over a 122m
strike along the main trend of the mineralization. It should be recognized that
the surface samples were primarily select samples of highly altered, silicified
intrusive rock that contained significant silica veinlets. Copper oxides with
very minor sulfides were present in many of the samples. It is likely that
sampling of the less altered rock away from the strongly silicified main trend
would result in lower gold and copper values.

MDA also sampled the 2007 drilling as shown on the following
table, also confirming the presence of significant gold and copper
mineralization within the 2007 Saratoga drill holes.

As duplicate check assays, the MDA results from this small
sample population showed high variability within the higher-grade ranges for
gold. Six sample pairs had a >30 percent difference, with five of the six
assaying >1.71g Au/t, and the highest-grade sample (17.622g Au/t) showing a
125 percent difference. These results indicate the potential within the deposit
for erratic, potentially coarse free gold, especially within the shallow oxide
and mixed oxide/sulfide mineralization. Copper values were more consistent with
just two samples with >30 percent difference. The MDA gold values also have a
significant high bias versus the original assays with an average 18 percent
increase in gold content for the MDA samples. Only three MDA samples had lower
gold values than the original assays. There is no apparent bias for the copper
analyses. The cause of the gold bias has not been determined, and further
duplicate analyses are warranted.

Summary Statement on Data Verification

The data verification procedures support the geologic
interpretations and confirm the database quality. Therefore, the Copper King
database is adequate for use in estimating and classifying a Mineral Resource.
Principal findings from the data verification are:

| | 1) | The Saratoga collar, down-hole survey, and assay
      databases are of high quality with only minor errors noted and
      corrected.

| | 2) | The drill data support the geologic interpretations and
      style of mineralization used in the resource model.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
| | 3) | The QA/QC data indicate that the gold and copper data are
      sufficiently accurate for use in Mineral Resource estimation.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
| | 4) | The limited quantity of original drill data results in a
      restriction of Mineral Resource classification to Inferred and Indicated
      only for the pre-Saratoga drilling. In the context of the large
      bulk-tonnage nature of the deposit and the consistency of gold and copper
      grades, both within and between drill campaigns, it is not believed that
      the lack of original data creates a significant concern in the estimation
      and classification of the resource. MDA recommended that a comprehensive
      program of quality assurance duplicate sampling, including pulp, coarse
      reject, RC rig, and quarter core, be continued throughout the life of the
      project.

Metallurgical Testing

Neither Energy Fuels nor Strathmore have conducted
metallurgical testing to date. However, the previous owner, Saratoga Gold, did a
fairly extensive test set of which the samples are currently controlled by
Energy Fuels and kept at the Riverton Office.

Mineral Resource Estimates

Historic Resource Estimates

At least seven historic mineral resource/reserve estimates have
been calculated for the Copper King property as shown on the following table.
The reader is cautioned that these historic resource estimates were made prior
to the implementation of NI 43-101 reporting requirements, do not conform to
those requirements, and should not be relied on as being indicative of a
resource or a reserve with demonstrated economic viability.

climate.


The apparent large range of tonnes and grades of these historic
estimates is likely due to varying metal and cut-off grades and terminology
definitions.

Current Resource Estimates

A summary of the total Copper King stated resources are
tabulated in the following two tables. The stated resource is fully diluted to
6.1m by 6.1m by 6.1m blocks (20ft by 20ft by 20ft) and is tabulated on a AuEq
cutoff grade of 0.514g AuEq/t (0.015oz AuEq/ton). All material, regardless of
which metal is present and which is absent, is tabulated. Because multiple
metals exist, but do not on a local scale co-exist, the AuEq grade is used for
tabulation. Using the individual metal grades of each block, the AuEq grade is
calculated using the following formula:

g AuEq/t = g Au/t + (2.057143 * %Cu)

This formula is based on prices of $1,000.00 per ounce gold,
and $3.00 per pound copper. No metal recoveries are applied, as this is the in
situ resource.

The Copper King resource contains oxide, mixed oxide-sulfide, and sulfide rock types. At the stated AuEq cutoff grade of 0.51g AuEq/t (0.015oz AuEq/ton), approximately 80% of the resource is sulfide material with the remaining 20% split evenly
between the oxide and mixed rock types.

For the Copper King deposit, the most important observation that can be presented to the reader is the even, consistent distribution of gold and copper, albeit generally low-grade, throughout this potential open-pit deposit. Approximately 85% of the
total resource is classified as Measured or Indicated due to the consistent nature of the mineralization and the current drill spacing. Additional drilling within the currently defined deposit is not expected to materially change the existing
resource.

Adjacent Properties

Although there are formerly active mines and prospects in the Silver Crown mining district, modern exploration has been focused on the Copper King mine area. There are no known mineral deposits or advanced mineral exploration projects on property
adjacent to Copper King.

Other Relevant Data And Information

Hausel (1997) had speculated that the known resource at the Copper King deposit might be increased based on the presence of geochemical and geophysical anomalies. He cited a large (305m by 610m with a 450-gamma magnitude) magnetic anomaly in a
gravel-covered area 1,372m southeast of the Copper King deposit that resembles the magnetic signature over Copper King. The covered anomaly yielded anomalous values in mercury, zinc, and arsenic in overlying soil samples. Hausel (1997) also reported
that there is geological and geophysical evidence for sulfides existing down plunge to the southwest and to the east of the Copper King deposit. Finally an IP survey showed a moderate to weak metal-factor anomaly that trends east-northeast of the
principal area of mineralization (Klein, 1974).

Interpretation And Conclusions

Copper King is a gold-copper deposit hosted within Precambrian foliated intrusive rocks and apparently controlled by a N60oW-trending shear zone. Most of the mineralization is in silicified, re-healed, mylonitic granodiorite, while lesser
amounts of primary copper minerals are present in younger felsic and mafic intrusive dikes. There is a general spatial relationship between mineralization and the dikes, though both might have been localized within the shear zone and not genetically
related. Mineralization is present as disseminated sulfides and within thin quartz vein stockworks, with malachite, chrysocolla and native copper, present at the surface and chalcopyrite, pyrite, minor bornite, pyrrhotite, and native copper at
depth. Chalcocite is dominant within a mixed oxidation zone that occurs at the oxide/sulfide interface. Within the near-surface high-grade core of the deposit, the mixed zone forms a keel that can be up to 100m deep beneath the approximate 30m oxide
zone. Gold occurs as free gold in grains 10 to 250 microns in size. In the better-mineralized areas, quartz occurs in numerous veinlets, and there is a direct quantitative relationship between the quartz veinlets, chalcopyrite, and gold content.

Successive drilling campaigns by various operators, including Saratoga’s 2007-2008 drill program, have resulted in the deposit being drilled out on approximate 15 to 20m centers within the near-surface high- grade core and to over 60m centers
at depth and along strike within the lower-grade shell. The Copper King deposit is defined by 120 drill holes totaling 18,105m, with over 60% of the drilling being core.

The SGS metallurgical test results indicate that gold and copper can be recovered from the sulfide and mixed oxide/sulfide portions of the Copper King deposit using standard flotation processes and that a marketable copper concentrate, containing
significant gold, can be produced.

It is proposed that the Copper King gold-copper deposit be mined by open pit methods with copper and gold recovery by flotation. This study assumed material would be processed at a rate of 10,000 tons per day. The ore-grade material would be crushed
in or near the mine and transported to the plant located close to the mine. The pre-tax economic analysis of the project shows a 31.2% internal rate of return, and a Net Present Value (5%) of $159.5 million.

Permitting

To date, no concentrated environmental studies have been performed on the Copper King property. No known environmental liabilities exist on or near the Copper King property at the time. There are no apparent fatal flaws or excessive permitting
requirements that would be prohibitive to obtaining a future Mining Permit; however, careful planning and coordination with the Wyoming Department of Environmental Quality would streamline the permitting process and allow for the early
identification of ways to address items of critical concern like groundwater hydrology.

Non-Material Mineral Properties

This section describes additional non-material mineral
properties in the Western U.S. and Newfoundland held by the Company. As these
projects are not considered material to Energy Fuels business, the Company is
pursuing the potential sale, joint venture, trade or other transaction involving
one or more of these projects.

The Company holds additional non-material mineral properties in
the Western U.S. and in Saskatchewan as follows:

Other Colorado Plateau Projects:

Overview:

The Company holds the Rim mine, Van 4 mine, and the Sunday
Complex, which includes the Sunday/St. Jude, West Sunday, Topaz and Carnation
mines. All of these mines are permitted and on standby. However, they will
require varying degrees of additional development and permitting for expansion
prior to being put back into production. They are located approximately 65 to
152 road miles from the Companys White Mesa mill. Haulage of the ore from the
mines to the mill is along County, State and U.S. highways.

The uranium/vanadium deposits in the Colorado Plateau District
are hosted by sandstone formations which resulted from deposition of clastic
material by braided streams. The shape and size of the mineralized zones are
extremely variable. As a result, exploration and mining have historically
involved conducting exploration to find a zone and then merely following its
erratic path, with little exploration other than development drilling in the
course of following the mineralization. The sporadic and ill-defined nature of
these deposits has traditionally resulted in a limited amount of operational
resources being dedicated to delineating future mineral resources or mineral
reserves prior to mining.



Operations:

The Sunday/St. Jude, Topaz, and West Sunday mines are all
accessed by declines from the surface. The Rim mine is a combination of a shaft
and decline access but at the present time is only accessed through the decline.
The Van4 property includes a shaft and associated surface facilities, which need
renovation. The mine is connected to the Ura decline on claims in Bull Canyon to
the southwest, not owned by Energy Fuels. It has been on standby for many years.
Denison completed reclamation of two of the ventilation holes in 2008 and 2010.
The Sunday/St. Jude, West Sunday, and Rim mines are mature operating, or
formerly operating mines, with extensive underground workings. The Topaz mine is
relatively new with the initial development drift completed in 2007. The mining
method at all of these properties is random room and pillar in which no set pillar
pattern is established but rather both the size of the rooms and the pillars are
variable and are defined by the deposit geometry. A typical room is about 20
feet wide with pillars as small as 12 feet square in highly mined areas.

The uranium-vanadium deposits in these mines occur in the upper
and middle sandstones of the Salt Wash Member of the Morrison Formation. Only
the Rim Mine deposits have an unusually high V2O5: U3O8 ratio; the last milled
at the White Mesa Mill had a 10:1 ratio.

For the majority of these properties, Energy Fuels is in
possession of much historic mine and drill data as well as up to date mine maps.

Because of the limited thickness of the mineralization, mining
must be selective in order to maintain a satisfactory production grade. This is
done by following the mineralized zones closely and by the technique of split
shooting wherein the ore and waste are blasted separately in a two-stage
operation.

As a result of declining uranium prices, Denison placed the
Topaz mine on standby in January 2009. In March 2009, Denison placed the Rim and
Sunday/St. Jude mines on standby, followed by the West Sunday mine which was
placed on standby in October 2009. The Van #4 Mine has been on standy for many
years.

The ore production by mine for 2007 through September 2012 is
shown below.

*Production from all mines since June 30, 2012 has been for the
account of Energy Fuels. All other production has been for the account of the
previous owner, Denison Mines Corp.

No Mineral Reserve or Resource estimates have been prepared in
accordance with NI 43-101 for any of these mines. The uranium grades shown above
are based on probe grades taken when the ore arrives at the White Mesa Mill. The
vanadium grades are based on historical uranium/vanadium ratios.

Permitting:

The Sunday, West Sunday, Saint Jude, Carnation, and Topaz Mines
and the Van 4 Mine are located in Colorado. These mines have existing permits
with the BLM and the CDRMS. In 2008, Colorado revised its Mined Land Reclamation
Act to define all uranium mines in the state as Designated Mining Operations
(DMOs). DMOs are required to submit an Environmental Protection Plan
(EPP) that identifies the methods the operator will utilize for
protecting human health, wildlife, property and the
environment from potential toxic or acid forming material associated with the operations. The EPP must be submitted to the Colorado Division of Reclamation, Mining and Safety (“CDRMS”) for review and, after approval by CDRMS, will
be subject to public comment.

The EPPs for the Sunday Complex and the Van 4 mine were filed in 2009 and subsequently approved by CDRMS on May 10, 2012. Pursuant to the Sunday Complex EPP, groundwater monitoring wells were installed at the mine and ore pad liners must be
installed prior to recommencement of mining.

In February 2009, the BLM approved an amended Plan of Operations (“PO”) for the Topaz mine, which included all of the mines in the Sunday Complex.  The amendment provided for additional surface expansion, construction of new vent
shafts, and future exploration drilling. The BLM also determined that there was a Finding of No Significant Impact (“FONSI”), as a result of its Environmental Assessment (“EA”) of the project. CDRMS had already
approved the conversion of the Topaz mine 110 permit to a 112 permit, which will allow additional disturbance as needed for development and production at Topaz.

For the Rim Mine, the mine and permits were transferred to Energy Fuels Nuclear in 1994, then to International Uranium (1997), then to Denison Mines (2007), and finally to Energy Fuels in 2012. Denison restarted the mine in 2008. The mine was
dewatered, but only several thousand tons of ore were mined before it was shut down. Dewatering continued until Energy Fuels shut the pumps down in the Fall of 2012. The original mine permits were for 13.3 acres; however, agency inspections in 2009
identified additional areas of disturbance. An updated Large Mine NOI, which doubled as a Plan of Operations, was submitted to both DOGM and the BLM in 2010 for 16 acres of disturbance. This plan was approved and the bond was increased
proportionally. The current bond amount is about $113,000. The facility has a surface water discharge permit that dates back to the early 1980s, but does not require a ground water discharge permit based on the local geologic conditions. A Small
Source Exemption is in place for air emissions. Radon emissions have been reported to DAQ using alpha track methods; however, Energy Fuels and DAQ do not have a copy of the original Umetco construction application and EPA approval documents from the
late 1980s. Energy Fuels plans to submit a new construction application to DAQ prior to restarting the mine. Energy Fuels recently received a Notice of Violation for radium exceedances in the discharge water during 2012 from WQD; however, the
exceedances are minor and may be due to laboratory error. Existing major permits at the mine include:

- Large Mine NOI M-037-006 (DOGM)
- Plan of Operations SJ-84-IP (BLM)
- UPDES Permit UT0023922 for surface water discharge (DWQ)
- Small Source Exemption DAQE-EN01422520001-10 for air emissions (DAQ)

The Van #4 Mine Permit (M-97-032 with DRMS) is currently in good standing and bonded for $75,057. Amendment AM-1, which incorporated the approved EPP, was issued on May 30, 2012. The permit has been transferred over the years from IUC to Denison
Mines (USA) Corp. to Energy Fuels Resources (USA) Inc. BLM’s Uncompahgre Field Office in Montrose occasionally inspects the site and the Plan of Operations for the mine is the same as the 1997 DRMS application. Permit compliance is currently
limited to an annual stormwater inspection; stormwater improvement work was completed in 2010 and 2012. The air permit with APCD was recently allowed to lapse, as the company does not have any immediate development or operation plans for the mine.
The mine does not have EPA approval for radon emissions; however, this approval may not be needed to restart mining, as the life-of-mine production will likely be less than 100,000 tons. Existing major permits at the mine include:

- BLM Plan of Operations COC-62522 (same as DRMS Permit M-97-032)
- DRMS 110d (Small Mine, DMO) Mine Permit M-97-032e

In March 2009, the Sheep Mountain Alliance, the Colorado
Environmental Coalition, the Information Network for Responsible Mining and the
Center for Biological Diversity jointly filed a petition to the BLM State
Director for review of the approved PO and the FONSI and requested a stay of the
Record of Decision (ROD). The petition focused on BLMs alleged failure
to review indirect and cumulative impacts, as well as inadequate review of water
quality impacts.

The BLM State Directors Office completed its review of the ROD
regarding approval of the amendment of the PO for the Sunday Mines in September
2009. The stay was denied; however, the State Director remanded the ROD back to
the local field office for further study and analysis. The majority of the data
collection requirements mandated by the remand decision have been fulfilled and
the reports of findings have been submitted. Four monitoring wells were
installed in late 2012 and 2013 and are being monitored on a quarterly basis.
Once sufficient ground water data has been collected, the PO will be updated and
a new EA will be prepared.

The Van 4 mine was originally permitted by Union Carbide in the
late 1970s and early 1980s with the CDRMS and BLM as part of a much larger
project. The mine was re-permitted with the CDRMS and BLM in 1999 as a smaller
project. These permits are in good standing and a reclamation bond of $75,057 is
in place. The mine would require additional permits, including an air permit,
before mining could be restarted.

The Rim Mine was developed in the early 1970s by Atlas Minerals
and was permitted in the late 1970s and early 1980s with DOGM and the BLM when
their respective environmental programs were implemented. The original mine
permits were for 13.3 acres; however, agency inspections in 2009 identified
additional areas of disturbance. An updated Large Mine NOI and Plan of
Operations were submitted to DOGM and the BLM, respectively, in 2010 for 16
acres of disturbance. These plans were approved and the bond was increased
proportionately. The facility has a surface water discharge permit that is in
good standing; however, dewatering operations were discontinued in early 2013. A
Small Source Exemption is in place for air emissions.

The Company considers the Sunday Complex, Rim mine and Van 4
mine to be non-material properties.

San Rafael Project:

Energy Fuels has filed a technical report dated March 21, 2011
entitled NI 43-101 Technical Report on the San Rafael Uranium Project
(Including the: Deep Gold Uranium Deposit and the Down Yonder Uranium Deposit)
Emery County, Utah, prepared by O. Jay Gatten, Utah Professional Geologist in
accordance with NI 43-101 (the San Rafael Technical Report). The author
of the San Rafael Technical Report is a qualified person and is independent
of the Company within the meaning of NI 43-101. A copy of the San Rafael
Technical Report is available under the Companys profile on SEDAR at
www.sedar.com. The San Rafael Uranium Project, located in east-central
Emery County, Utah, is owned by the Company through its subsidiaries Magnum USA
and EFRC. The Company added additional properties to the San Rafael Project area
through its acquisition of Titan. These properties are known as the Green River
South properties, and are located south of the San Rafael Project area. The
Company sold its ownership position in the Green River South property to
Aldershot in August 2013. For purposes of the San Rafael Technical Report, no
economic evaluation of the mineral resources was performed. Thus, the following
estimate is solely a Mineral Resource. The combined Indicated Mineral Resource
for the entire San Rafael Project comprises a resource of 758,000 tons @ 0.225%
eU3O8 containing 3,404,600 lbs. of U3O8 and an Inferred Mineral Resource of
453,800 tons @ 0.205% eU3O8 containing 1,859,600 lbs. of U3O8. Using the
historic District average recovered U3O8: V2O5 ratio of 1:1.35, this same
tonnage could yield Indicated Mineral Resources of approximately 4,596,000
pounds

V2O5 at an average grade of 0.30% V2O5. The same Inferred
Mineral Resource tonnage could yield approximately 2,510,000 pounds V2O5 at an
average grade of 0.28% V2O5.

The Company considers the San Rafael Project to be a
non-material property.

Willhunt:

Energy Fuels has filed a technical report dated October 10,
2008 entitled Amended Technical Report On Energy Fuels Resources Corporations
Willhunt Property, San Miguel County, Colorado, prepared by Douglas C. Peters,
Certified Professional Geologist, of Peters Geosciences, Golden, Colorado, (the
Willhunt Technical Report). A copy of the Willhunt Technical Report is
available under the Companys profile on SEDAR at www.sedar.com. Energy Fuels
has leased the Willhunt property (40 unpatented claims) from Ur-Energy since
September 14, 2006. The drilling program concentrated mainly on expanding the
deposits that have been drilled previously. The historic drill hole data and the
Energy Fuels drilling show two clear mineralized sandstone channels trending
NW/SE, paralleling the ridge. A total of 15 holes were drilled in August 2008,
totaling about 9,500 feet. The depths ranged from 540 to 680 feet. Results were
generally favorable. This drilling was after the Willhunt Technical Report was
initially filed, and not discussed in the Report Technical. Drill indicated
resources were expanded considerably. The drilling produced five ore holes, one
sub ore hole and two mineralized holes. This resulted in approximately 66,000
lbs. of U3O8 and 330,000 lbs. of V2O5 (not considered compliant at this time)
that have not been added to the reported 43-101 resources. The 2008 drilling
confirmed the continuance of the channel in the exploration areas of the
Report. Since this is a non-material property, the Report has not yet been
updated. The Willhunt property is contiguous with the Sunday Mine Complex
property.

The Company considers the Willhunt project to be a non-material
property.

Farmer Girl:

Energy Fuels has filed a technical report, dated October 8,
2008 entitled Amended Technical Report On Energy Fuels Resources Corporations
Farmer Girl Property, Montrose County, Colorado, prepared by M. Hassan Alief,
Certified Professional Geologist, Alinco GeoServices, Inc. Lakewood, Colorado
(the Farmer Girl Technical Report). A copy of the Farmer Girl Technical
Report is available under the Companys profile on SEDAR at www.sedar.com.
Energy Fuels has leased the Farmer Girl property (29 claims) from Monogram
Mining since October 1, 2006. Two drill projects have been completed on the
Farmer Girl claims in 2007 and 2008. The 2007 Energy Fuels drilling is described
in the Farmer Girl Technical Report. In 2008 subsequent to the Farmer Girl
Technical Report, 12 holes were drilled. Results were generally favorable. Of
the 12 holes drilled, five holes had a one foot zone ranging from 0.23 to 0.36%
eU3O8. Another two holes had five feet of 0.03% eU3O8 showing a favorable
environment. This resulted in approximately 18,000 lbs. of U3O8 and 85,000 lbs.
of V2O5 additional, above the reported NI 43-101 resources, though not
considered compliant since the report has not been updated yet. The 2008
drilling confirmed the presence of mineralization in the exploration target
areas. More drilling is needed to enlarge the known resources in order to make a
decision as to go forward with permitting. Energy Fuels has approved drilling
permits for another 15 holes.

The Company considers the Farmer Girl project to be a
non-material property.

Torbyn:

Energy Fuels has filed a technical report, dated January 7,
2009 entitled Amended Technical Report On Energy Fuels Resources Corporations
Torbyn Property, Mesa County, Colorado, prepared by M.

Hassan Alief, Certified Professional Geologist, Alinco GeoServices, Inc. Lakewood, Colorado (the “Torbyn Technical Report”). A copy of the Torbyn Technical Report is available under the Company’s profile on SEDAR at
www.sedar.com. Energy Fuels has leased the Torbyn (Tenderfoot Mesa) property (70 claims) from Rimrock Exploration and Development, Inc. since July 1, 2006. Four drill projects have been completed on the Torbyn claims in 2007, 2008, 2009 and 2012.
The 2007 Energy Fuels drilling is described in the Torbyn Technical Report. Subsequent drilling (12 holes drilled in 2008 total 4,755 ft. and in 2009, six holes were drilled which total 2,350 feet) added resources in the exploration target areas
defined in the Report by approximately 51,500 lbs. of U3O8
and 206,000 lbs. of V2O5 which is not considered compliant at this time.  The drilling in 2012 was designed to look for extensions of
the mineralization in three directions near the mine, finding the sandstone to be very favorable in one of those directions. More drilling is needed to enlarge the known resources near this mine in order to make a decision as to go forward with
permitting.

The Company considers the Torbyn project to be a non-material property.

Other New Mexico Projects:

Nose Rock Project:

The Nose Rock project is a uranium development project located
within the Grants Mineral Belt in the State of New Mexico northeast of the town
of Crownpoint. The Nose Rock project as a whole consists of approximately 5,000
acres of land, including 102 federal lode mining claims and six (6) State of New
Mexico Mineral Leases.

On March 19, 2009, Strathmore filed on the SEDAR website at
www.sedar.com, the technical report entitled "Technical Report on Section
1, T18N, R12W, Nose Rock Uranium Property, McKinley County, New Mexico," dated
February 9, 2009, prepared by M. Hassan Alief, M.Sc., CPG, in accordance with NI
43-101 (the Nose Rock Technical Report). A copy of the Nose Rock
Technical Report is available under Strathmores profile on SEDAR at
www.sedar.com. The author of the Nose Rock Technical Report is a qualified
person and is independent of the Company within the meaning of NI 43-101.



The Nose Rock project was acquired by the Company on August 29,
2013 as a result of the acquisition of Strathmore by Energy Fuels. See
General Development of the Business  Significant Acquisitions  Acquisition
of Strathmore Minerals Corp. above. Strathmore acquired the property
through mineral leases or by claim staking.

The Company considers the Nose Rock project to be a
non-material mineral property.

Dalton Pass Project:

The Dalton Pass project is a uranium development project
located in the western part of the Grants Mineral Belt in the State of New
Mexico. It consists of approximately 1,320 acres of federal lode mining claims.

On March 19, 2009, Strathmore filed on the SEDAR website at
www.sedar.com, the technical report entitled "Technical Report on Section
32, T17N, R13W, Dalton Pass Uranium Property, McKinley County, New Mexico,"
dated January 30, 2009, prepared by M. Hassan Alief, M.Sc., CPG,, in accordance
with NI 43-101 (the Dalton Pass Technical Report). A copy of the Dalton
Pass Technical Report is available under Strathmores profile on SEDAR at

The Dalton Pass project was acquired by the Company on August
29, 2013 as a result of the acquisition of Strathmore by Energy Fuels. See
General Development of the Business  Significant Acquisitions  Acquisition
of Strathmore Minerals Corp.above. Strathmore acquired the property
through claim staking.

The Company considers the Dalton Pass project to be a
non-material mineral property.

Church Rock Project:

The Church Rock project is a uranium development project
located in the State of New Mexico. It consists of approximately 640 acres of
federal lode mining claims.

The Church Rock project was acquired as a result of the
acquisition of Strathmore by Energy Fuels. See General Development of the
Business  Significant Acquisitions  Acquisition of Strathmore Minerals Corp.above. Strathmore acquired the property through claim staking.

An historical measured and indicated mineral resource estimate
for the Church Rock project reported by Kerr-McGee in 1979 totaled 10.9 million
pounds eU3O8 based on 6,050,000 tons at an average grade of 0.09% eU3O8. Kerr
McGee's measured and indicated mineral resource categories are most likely
comparable to CIM Measured and Indicated mineral resource categories. In 1995,
Rio Algom LLC, the successor company to Kerr-McGee, prepared a resource estimate
utilizing Kerr-McGee's methodology, but using a higher cut-off grade of 5 feet
of 0.10% . Rio Algom calculated an historical measured resource estimate
totaling 5,426,000 lbs eU3O8 based on 2,532,000 tons at an average grade of
0.11% eU3O8, an indicated resource estimate totaling 76,000 lbs eU3O8 based on
34,000 tons at an average grade of 0.11% eU3O8, and a total measured &
indicated resource estimate of 5,502,000 lbs. eU3O8 based on 2,564,000 tons at a
grade of 0.11% eU3O8.

The Company cautions readers that the Company is not treating
either of these two historical resource estimates as current mineral resources.
The Kerr-McGee and Rio Algom historical measured and indicated resource
estimates stated above were completed prior to the implementation of NI 43-101.
Given the extensive mineral production in the Church Rock and Crownpoint areas
(approximately 16 million pounds), the experience and reputation of the
companies, and the quality of their historical work, the Company believes these
historical resource estimates to be relevant and reliable. However, a qualified
person has not completed sufficient work to verify and classify these historical
resource estimates as current Mineral Resources, and the Company is not treating
the historical resource estimates as current Mineral Resources or Mineral
Reserves. Additional work including confirmation drilling, sampling and chemical
assay verification, and other technical support work as deemed necessary, is
required in order to verify the historical estimates as a current mineral
resource.

The Company considers the Church Rock project to be a
non-material mineral property.

Marquez Project:

The Marquez Project is a uranium development project located in
the eastern part of the Grants Mineral Belt in northwestern New Mexico. It
consists of approximately 14,501 acres of a private mineral lease. It was
extensively explored during the 1970s, including 384 drill holes completed, and
was being developed as a full-scale underground uranium mine by Kerr McGee and
the Tennessee Valley Authority. However, the project was later abandoned in the
1980s due prolonged weak uranium prices. Strathmore acquired rights to the
Marquez property in 2007.

Exploration Properties

Department of Energy (DOE) Lease Tracts:

Energy Fuels was the successful bidder in May 2008 on four of the DOE tracts offered for lease in the Uravan Mineral Belt in western Colorado (C-SR-16A, C-CM-24, C-G-26, and C-G-27). Three other leases were acquired by Energy Fuels, the second
highest bidder, in 2009 when the initial lessee did not renew (C-SR-12, C-AM-19A and C-AM-20). A fourth lease was assigned to Energy Fuels from the initial lessee, Zenith Minerals, in 2010 (C-AM-19). A lawsuit filed against DOE in November 2008 by
nongovernmental organizations alleged DOE should have performed an EIS on each individual lease tract instead of a Programmatic Environmental Assessment (PEA) on the combined leases. The court ruled in favor of the plaintiffs in June 2011. In the
ruling, the court ordered the preparation of a Programmatic Environmental Impact Study, which is currently underway. The court also stayed the leases in June 2011, prohibiting any surface disturbing work until the EIS is completed. DOE therefore
suspended the annual lease payments until the final decision on the EIS. DOE will also add onto the end of the lease initial term the length of time it takes from the stay until the Final EIS record of decision (“ROD”), assuming
the decision allows work to resume. The draft EIS was made available for public comment in February, 2013. Presently, DOE estimates that on March 21, 2014 the Final EIS will be made available for publishing in the Federal Register and the ROD will
be issued no later than April 28, 2014. If the ROD allows the leasing program to continue, no annual payments to continue to hold the leases will be due until a year after the ROD since the lease payments were made for a year in advance at the same
time the suit stayed the leases. There is the potential for mineralization on these leases.

The Company considers these properties to be non-material.

HC Claims (Calamity Mesa):

Energy Fuels has leased the HC claims on Calamity Mesa (45 claims) from Rimrock Exploration and Development, Inc. since March 8, 2007. Three drill projects have been completed on the HC claims in 2007, 2008, and 2009. The 2007 project focused on
exploring near the southwest end of the historic New Verde mine. The other two projects were in the area just south of the historic resource north of the New Verde mine on the adjoining DOE lease, C-G-26.  Energy Fuels has maps by the previous
operator showing the mine workings and historic drilling. It will remain a low-priority exploration project until the DOE EIS is complete.

The Company considers these properties to be non-material.

Yellow Cat (Ethan and YC claim groups, plus Utah State leases):

The Ethan exploration project (27 claims) was purchased from Future Energy in 2006. Future Energy retained a 2% overriding royalty. The Company also acquired a Utah (SITLA) Mining Lease in 2012 through the competitive bid process.  The 58 YC claims
are contiguous, as are the two other SITLA Leases. Denison acquired the claims and leases from WCUL in 2011. Historic drilling, mostly by Pioneer Uravan in the 1970’s has identified a moderate-sized deposit in the Salt Wash on this claim
group. There has been no exploration by Energy Fuels to date, but the larger property is retained for the good potential due to location near historic mines and other historic drilling.

The Company considers these properties to be non-material.

Mag Pie/Dry Creek:

Energy Fuels entered a Mining Lease Agreement with Sutherland
Brothers Drilling in December 2010 covering 118 claims, of which 61 are still
held. The property was originally offered to Energy Fuels by Zenith Minerals;
however, Zenith Minerals still owed a rather large final installment to
Sutherland Brothers. Zenith Minerals returned the property to Sutherlands,
allowing for the Energy Fuels acquisition, with Zenith Minerals retaining a 2%
overriding royalty. The property is on the north side of Gypsum Valley and
includes several historic producing mines, including some of the Mexico group
and the Sego mine. The Company terminated the lease in June 2013. To the east of
the Mag Pie property is the Dry Creek claims. One hundred claims were staked by
Denison covering a prospective area with minor historic exploration drilling,
some showing favorable conditions for uranium deposition. In August 2013, the
Company dropped all but the most prospective 18 claims.

The Company considers these properties to be non-material.

Avocet:

Denison staked five claims in 2007 in an area known to contain
a small historic deposit based on drilling by Cotter Corporation. The property
is about 41⁄2 miles southeast of the Whirlwind Mine.

The Company considers these properties to be non-material.

West Lisbon JV (Mesa-BZU); DAR-RAD claims:

Energy Fuels and Mesa Uranium Corporation (along with its
subsidiary, BZU Holdings, Inc.) formed a joint venture, called West Lisbon LLC,
in May 2008 for future exploration on a group of 60 claims (the DAR group)
located north and west of the north end of the Lisbon Valley uranium district.
Energy Fuels is the manager for both exploration and mining on the joint venture
properties. The most prospective target is the basal channel sandstones and
conglomerates of the Triassic Chinle formation, known as the Moss Back member.
The Moss Back has produced approximately 70,000,000 lbs. of U3O8 from historic
mines in the Lisbon Valley/Big Indian District. The underlying Permian Cutler
formation is also prospective, consisting of interbedded sandstones and
mudstones. There has been about 8,000,000 lbs. of uranium produced from the
Cutler in the same district. An angular unconformity exists between the Chinle
and the Cutler with the Cutler dipping steeper to the west than the Chinle beds.
Deposits in the Cutler form where Cutler sandstones are in contact with the Moss
Back, and continue short distances down dip of the contact. The Chinle and
Cutler target horizons range from about 1,000 feet to 1,350 feet deep. Historic
wide-spaced exploration drilling by Energy Fuels Nuclear in the late 1980s
encountered scattered mineralization (from 0.02% up to 0.22% eU3O8) in 50% of
the holes drilled on land now covered by the DAR claims.

On December 1, 2010, an amendment was made to add 34 more
claims to the West Lisbon LLC. The RAD claims were staked by BZU Holdings in
April 2007. Mesa offered these to West Lisbon LLC under the same terms as the
DAR; that is a 50:50 shared expenditure agreement to conduct exploration. The
RAD claims lie contiguously along the east side of the DAR group. This is the
up-dip direction where the target horizons are somewhat shallower. The RAD group
boundary is less than 1⁄2 mile west of the historic producing North Alice
(slightly over 4.5 million pounds historic production), Far West, and Radon
mines.

Due to the lack of data, Energy Fuels does not carry any
historic resources on the DAR claims, nor on the newly acquired RAD group.
Vanadium occurs in both the Chinle and Cutler at concentrations too low to be
economic in the northern Lisbon Valley District. No exploration drilling is
planned until there is a sustained higher price for uranium.

The Company considers these properties to be non-material.

Cedar Mountain:

Energy Fuels acquired control of this project in the 2009
acquisition of Magnum USA. It is an exploration play. It consists of one SITLA
LEASE in Section 36, T18S, R10E, S.L.M., and 29 federal lode mining claims. The
Cedar Mountain property lies just west of the north-plunging axis of the San
Rafael Swell, about 20 miles northwest of the San Rafael Project area. The
deposit lies wholly in Section 36, which is a plateau capped by the Buckhorn
Conglomerate. Below the Buckhorn is the Brushy Basin Member of the Jurassic
Morrison Formation composed of fine-grained clastic rocks including claystone,
limy claystone and mudstone, mudstone, siltstone, and sandstone. The uranium
mineralization is situated in the upper portion of the Brushy Basin. A total of
61 holes have been drilled in the area of the deposit. Mineralized intercepts
range from 1.5 - to 68-feet thick, but average about 25-feet thick. Corrected
grades (due to disequilibrium) range as high as 0.16% eU3O8, but average about
0.052% eU3O8. Holes containing material grading up to 0.6% eU3O8 and 0.7% eU3O8
exist west of and below the plateau rim and have not been off-set.
Mineralization is about 100 to 120 feet below the surface.

The Company considers these properties to be non-material.

Arizona Strip Properties

On June 30, 2008 the Company along with Royal USA Inc. (a
subsidiary of Aldershot) completed the formation of the Arizona Strip Partners
LLC (ASP), a joint venture created to explore uranium properties on the
Arizona Strip located in Northern Arizona. The Company acquired Royal USA Inc.s
interest in the joint venture on October 1, 2012 (See Mineral Projects 
Sage Plain Project), giving the Company a 100% interest in ASP. ASP
currently owns a number of mining claims in Arizona that are in the exploration
stage, and have no underground or surface facilities. No exploration
expenditures are planned for these claims in FY 2014.

The Company considers these properties to be non-material.

Burnt Pond, Newfoundland:

Energy Fuels holds a 100% interest in the Newfoundland property
known as Burnt Pond which is prospective for both zinc and copper, consisting of
20 mining claims totalling 725 hectares. The property is located approximately
38 kilometers east of Buchans and approximately 55 kilometers west of Grand
Falls in the Tally Pond Belt of volcanic and sedimentary rocks of central
Newfoundland. In April 2008, the Burnt Pond mining claims were transferred to
Energy Fuels Exploration, Inc. a 100%-owned subsidiary of Energy Fuels Inc.

In August 2008, Energy Fuels personnel reviewed core data
samples held by the Canadian Government and were granted permission to access
raw data from a forthcoming survey to be completed by adjacent property holders.
Following the review and interpretation of such data, the Company explored the
possibility of optioning the property to another mining company for further
exploration. There is no expenditure commitment on this property. The annual
cost to maintain this property is approximately $600.

Due to uncertainty regarding the ability to sell the property
or enter into a joint venture with another mining company operating in the same
area, the Company chose to write-off all costs incurred to date in the amount of
$0.68 million.

Quality Assurance and Quality Control Procedures and
Protocols

The following section details the Quality Assurance and Quality
Control (QA/QC) procedures and protocols for all exploration programs
operated by Energy Fuels.

All uranium exploration technical information is obtained,
verified and compiled under a formal QA/QC assurance and quality control program
in the southwestern United States. The following details the protocols used by
all Energy Fuels staff and consultants.

Processes for Determining Uranium Content by Gamma Logging

Exploration for uranium deposits in the southwest United States
typically involves identification and testing of permeable sandstones within
reduced sedimentary sequences. The primary method of collecting formation is
through extensive drilling and the use of down hole geophysical probes. The down
hole geophysical probes measure natural gamma radiation, from which an indirect
estimate of uranium content can be made.

The radiometric (gamma) probe measures gamma radiation which is
emitted during the natural radioactive decay of uranium. The gamma radiation is
detected by a sodium iodide crystal, which when struck by a gamma ray emits a
pulse of light. This pulse of light is amplified by a photomultiplier tube,
which outputs a current pulse. The gamma probe is lowered to the bottom of a
drill hole and data is recorded as the tool is withdrawn up the hole. The
current pulse is carried up a conductive cable and processed by a logging system
computer which stores the raw gamma cps data.

If the gamma radiation emitted by the daughter products of
uranium is in balance (equilibrium) with the actual uranium content of the
measured interval, then uranium grade can be calculated solely from the gamma
intensity measurement. Down hole cps data is subjected to a complex set of
mathematical equations, taking into account the specific parameters of the probe
used, speed of logging, size of bore hole, drilling fluids and presence or
absence of and type of drill hole casing. The result is an indirect measurement
of uranium content within the sphere of measurement of the gamma detector.

The basis of the indirect uranium grade calculation (referred
to as "eU3O8" for "equivalent U3O8") is the sensitivity of the sodium iodide
crystal used in each individual probe. Each probe's sensitivity is measured
against a known set of standard "test pits," with various known grades of
uranium mineralization, located at the DOEs Grand Junction, Colorado office.
The ratio of cps to known uranium grade is referred to as the probe "K-Factor,"
and this value is determined for every gamma probe when it is first manufactured
and is also periodically checked throughout the operating life of each probe.
Application of the K-Factor, along with other probe correction factors, allows
for immediate grade estimation in the field as each drill hole is logged.

It is recognized that gamma logs are indirect measurements of
the amount of uranium present and must be validated. Typically, this process
consists of comparing equivalent uranium determined from gamma log
interpretations with chemical analyses of rock core recovered from core holes.
This process is subject to some degree of uncertainty because the gamma logs and
the chemical assays are obtained from different samples: core from the drill
hole itself and gamma readings from the material surrounding the hole. The age
of the sandstones and the uranium minerals in the deposits, coupled with the
groundwater regime, results in disequilibrium rarely being a problem in the
Colorado Plateau ores or in New Mexico. Analysis of chemical equilibrium of
uranium for the Grants Mineral Belt from historic drill reports and years of
production indicates that various relationships are present. In most areas and
deposits, uranium is in equilibrium, or is slightly enriched relative to gamma
determinations. Based on Kerr-McGees extensive operating experience in the Ambrosia Lake
sub-district, there were no historical concerns regarding disequilibrium for
gamma ray results at the Roca Honda deposit. Additionally, RHR cores showed no
major negative disequilibrium. The Wyoming roll front-type deposits are
considerably younger and have experienced more recent groundwater flow than the
Colorado Plateau deposits and are more prone to disequilibrium issues

188

---

At the Wyoming properties, two additional down-hole logging
methods have been employed. At Gas Hills, Strathmore used a Company-owned
Prompt-Fission-Neutron logging tool (PFN), gamma-ray probing tools, and select
chemical assays from core drilling, for the measurement of uranium in the Gas
Hills. Equivalent uranium values, expressed as eU3O8 are obtained from down-hole
gamma-ray probes, assuming that uranium and its daughter products are in
radiogenic equilibrium. The probes are standardized and calibrated using test
pits operated by U.S. Department of Energy, located in Casper, Wyoming and Grand
Junction, Colorado. PFN analysis assesses the quantity of uranium present
surrounding a drill hole directly by measuring neutrons fissioned from the U235
isotope, thus aiding in determining any disequilibrium which may be present.
This eliminates the uncertainties due to measuring the gamma radiation resulting
from decay of uranium daughter products, which may be subjected to selective
remobilization due to the varying chemical properties of each daughter element.
PFN also samples a larger sample than the typical 3 diameter core that is
obtained for chemical analysis. Many historic drill holes completed prior to
November 2012 have been logged using the PFN logging tool. It is anticipated
that, through regular ongoing use of PFN with its associated calibration checks
and continuing checks against existing or historical core holes, a background of
validity can be achieved which will reduce the number and frequency of future
chemical-assaying.

At the Sheep Mountain Project, in situ mineral grades for the
2009 drilling were determined by geophysical logging including both conventional
gamma logging and state of the art Uranium Spectrum Analysis Tool (USAT).
Crosshairs used USAT at Juniper Ridge on the 2011 drilling project, too. USAT is
a Century Geophysical logging service that directly measures uranium if
disequilibrium conditions exist. USAT employs a High Purity Germanium detector
that measures Protactinium 234, the second daughter element after Uranium 238.
USAT ignores the high volume gamma rays of Bismuth 214, Lead 214, and Radium 226
that the sodium iodide crystals measure. USAT does not need to be calibrated at
calibration pits, it is calibrated against a low-power, lab-style source. Like
PFN, it is sampling the rock surrounding the bore hole with a radius of
influence of about one foot.

Core Sampling, Processing, and Assaying

Core samples are collected for a number of purposes:
verification of lithology as determined from geophysical logging and examination
of drill cuttings, determination of uranium content as a general check of gamma
probing to determine if gamma measurement and chemical uranium content are close
to balance (this is referred to as "radiometric disequilibrium"), whole rock
analysis, and specific geochemistry for uranium species and other minerals of
interest. Typically core is only taken over select intervals of interest as
identified from logging of drill holes. This reduces the amount of core through
barren zones or horizons of no interest and greatly reduces overall exploration
costs.

Core diameter is typically 21⁄2  31⁄4 inches. For zones selected
for laboratory analyses, one half of the core will normally be used. The minimum
length of core submitted is usually one foot and the maximum length per sample
is two feet. Sample intervals are selected by geologists in the field based on
lithology, oxidation/reduction, and uranium grade (from gamma logging and from
hand-held gamma counters).

Core samples collected in Colorado, Utah, and Arizona are
prepared at the White Mesa Mill in Blanding, Utah. Samples are crushed and then
ground to -200 mesh. The sample pulps are split to 250 to 300 grams for
laboratory work. The samples collected in Wyoming have been sent to commercial
labs for analyses in accordance to industry standards. At Roca Honda,
RHR completed four pilot holes in 2007 and one geotechnical hole in 2011. These
samples were analyzed at a commercial lab, Energy Labs in Casper, Wyoming

Quality Assurance and Quality Control Measures

Drill hole logging is conducted by Energy Fuels in-house
personnel. The logging capabilities are designed specifically to meet Energy
Fuels logging requirements in the southwest United States. The tools, and a
complete set of spares, were manufactured by Mount Sopris Instrument Company in
Golden, Colorado. Energy Fuels has retained the services of a senior geophysical
consultant to oversee training, implementation, and quality control protocols
for the southwest United States operations. All tools are checked and
calibrated before being used in the southwest United States and a variety of
system checks and standards are also established for routine checking and
calibration of tools.

Drill hole logging data is stored on digital media in the
logging truck at the exploration sites. The digital data are periodically
brought in from the field locations to the Egnar, Colorado field office. The raw
and converted logging data are copied and then sent via e-mail to Energy Fuels
Denver, Colorado office, where all data is checked and reviewed.

The PFN truck is stored at the Riverton, Wyoming office. It and
the natural gamma logging tools are routinely calibrated at the Casper, Wyoming
test pits maintained by the DOE. The gamma logging equipment is the same make
and type as the units used in Colorado and Utah.

Samples of drill core are chosen on the basis of radiometric
data collected during core logging. This radiometric data is obtained by using a
hand held scintillometer. The general concept behind the scintillometer is
similar to the gamma probe except the radiometric pulses are displayed on a
scale and the respective count rates are recorded manually by the geologist
logging the core. The hand-held scintillometer provides quantitative data only
and cannot be used to calculate uranium grades. However, it does allow the
geologist to identify uranium mineralization in the core and to select intervals
for geochemical sampling.

Additional samples are collected above and below the horizons
of interest in order to "close-off" sample intervals. Sample widths are selected
according to radiometric values and lithologic breaks or changes. All reasonable
efforts are made to ensure that splitting of the core is representative and that
no significant sampling biases occur. Once the sample intervals are identified,
an exclusive sample number is assigned each interval and recorded by the on-site
geologist.

After the geological logging of the core and sample selection,
all of the selected sample intervals of drill core are split longitudinally at
the drill site. One half of the core is placed in a new sample bag along with a
sample tag corresponding to the sample number. The other half of the core is
re-assembled in the core box and stored for future reference. Samples collected
in Utah or Colorado are stored at the Egnar, Colorado office under the
supervision of the project geologists and delivered to either the White Mesa
Mill or Activation Laboratories Ltd. for preparation. As standard procedure,
field duplicates are included in assay suites sent to the laboratories, and
reference samples are used to verify laboratory controls and analytical
repeatability. The Wyoming sample splits are stored in Riverton at the Company
office. Chemical analysis for the Gas Hills drilling was performed by Hazen
Research of Golden, Colorado and Intermountain Labs of Sheridan, Wyoming. Core
samples are stored at various locked storage facilities in Wyoming and at the
Company office.

RHR has developed stringent in-house standard operating
procedures for core handling and decontamination of small equipment used for
sampling.

regular reporting to the Board regarding the Companys compliance and the
results of the Companys monitoring.

White Mesa Mill

The White Mesa Mill processed conventional ore through March
2012, at which time processing ceased for maintenance work. Conventional ore
processing recommenced at the Mill in August 2012 and continued until early June
2013. The alternate feed circuit was operating throughout FY-2012 and FY-2013.
The White Mesa Mill is expected to begin processing conventional ore again in
May 2014 until July 31, 2014. The alternate feed circuit is expected to process
materials until April of 2014. The Mill operations registered zero lost time
accidents in 2013.

Prior to Energy Fuels acquisition of the US Mining Division,
chloroform contamination in the shallow aquifer the White Mesa mill site was
discovered. The contamination appears to have resulted from the operation of a
temporary laboratory facility that was located at the site prior to and during
the construction of the mill facility, and from septic drain fields that were
used for laboratory and sanitary wastes prior to construction of the mills
tailings cells. In April 2003, Denison commenced an interim remedial program of
pumping the chloroform contaminated water from the groundwater to the mills
tailings cells. This action enables Energy Fuels to begin cleanup of the
contaminated areas and to take a further step towards resolution of this
outstanding issue. Pumping from the wells continued in 2013. Energy Fuels is
continuing to work with the State of Utah to develop a long-term Corrective
Action Plan (CAP). A draft of the CAP is currently being prepared by
the State. While the investigations to date indicate that this chloroform
contamination appears to be contained in a manageable area, the scope and costs
of final remediation have not yet been determined and could be significant.

Elevated concentrations of nitrate and chloride were observed
in some of the monitoring wells at the White Mesa Mill site in 2008 a number of
which are upgradient of the mills tailings cells. Pursuant to a Stipulated
Consent Agreement with UDEQ, Denison retained INTERA, Inc., an independent
professional engineering firm, to investigate these elevated concentrations and
to prepare a Contamination Investigation Report for submittal to UDEQ. The
investigation was completed in 2009, and the Contamination Investigation Report
was submitted to UDEQ in January 2010. INTERA concluded in the Report that: (1)
the nitrate and chloride are co-extensive and appear to originally come from the
same source; and (2) the source is upgradient of the mill property and is not
the result of Mill activities. UDEQ reviewed the Report, and concluded that
further investigations were required before it could determine the source of the
contamination and the responsibility for cleanup. Such investigations were
performed in 2010 and 2011, but were considered to be inconclusive by UDEQ. As a
result, after the investigations, it was determined that there are site
conditions that make it difficult to ascertain the source(s) of contamination at
the site, and that it was not possible at that time to determine the source(s),
causes(s), attribution, magnitudes of contribution, and proportion(s) of the
local nitrate and chloride in groundwater.

191

---

For those reasons, UDEQ decided that it could not eliminate
mill activities as a potential cause, either in full or in part, of the
contamination. The Company and UDEQ have therefore agreed that resources are
better spent in developing a CAP, rather than continuing with further
investigations as to the source(s) and attribution of the groundwater
contamination. Pursuant to a revised Stipulated Consent Agreement, Denison
submitted a draft CAP for remediation of the contamination to UDEQ in November
2011. The CAP proposes a program of pumping the nitrate contaminated groundwater
to the mills tailings cells, similar to the chloroform remedial program. UDEQ
approved the CAP on December 12, 2012. In accordance with the CAP, in 2013 the
Company commenced pumping nitrate/chloride contaminated water from four
monitoring wells for use in mill processing or discharge into the Mills process
or tailings cells. Although the contamination appears to be contained in a
manageable area, the scope and costs of final remediation have not yet been
determined and could be significant.

During 2011, 2012, and 2013, the White Mesa Mill reported
consecutive exceedances of groundwater compliance limits (GWCLs) under
the White Mesa Mills Groundwater Discharge Permit (GWDP) for several
constituents in several wells, and there are decreasing trends in pH in a number
of wells across the site that have caused the pH in a number of compliance
monitoring wells to have dropped below their GWCLs. These exceedances and pH
trends include wells that are up-gradient of the Mill facilities, far
down-gradient of the Mill site and at the site itself. These consecutive
exceedances of GWCLs have resulted in violations of the GWDP. Source Assessment
Reports were submitted in 2012 and 2013 addressing each exceedance and the
decreasing trends in pH at the site. UDEQ has accepted the Source Assessment
Report, and has concluded that such exceedances and decreasing trends in pH are
due to natural background influences at the site. UDEQ has agreed to revise the
GWCLs in the GWDP to account for these background influences, which would put
those constituents, including pH at the site, back into compliance.

The White Mesa Mill monitors radon flux from tailings Cells 2
and 3 to comply with the NESHAPs requirements of the Clean Air Act. The radon
flux from Cell 2 exceeded the regulatory threshold beginning with the June 2012
sampling event and continued to climb during subsequent sampling events, which
is believed to be due to the aggressive dewatering of the slimes drain solution
level in Cell 2 to comply with the Mills GWDP. Consistent with the regulations,
the Company initiated monthly monitoring of Cell 2 radon flux in April 2013. In
order to address the Cell 2 radon exceedances, in 2013 the Company commenced
placement of additional cover materials over areas showing high radon emissions,
to mitigate the radon flux from Cell 2. Current monthly monitoring indicates
that the radon flux from Cell 2 has dropped below the compliance threshold and
is now in compliance.

Reclamation

The White Mesa Mill is subject to decommissioning liabilities.
Energy Fuels, as part of the White Mesa License, is required to annually review
its estimate for the decommissioning of the White Mesa Mill site and submit it
to UDEQ for approval. The estimate of closure costs for the Mill is $21.1
million as of the date of this AIF, and financial assurances are in place for
the total amount. However, there can be no assurance that the ultimate cost of
such reclamation obligations will not exceed the estimated liability contained
in the Companys financial statements.

The Piñon Ridge Mill

On July 18, 2007, Energy Fuels acquired an 880 acre site
approximately 12 miles west of Naturita, Colorado in the ParadoxValley of western Montrose County, Colorado, on which to build the
proposed Piñon Ridge Mill. The site is large enough to accommodate the proposed
mill, which would be the first conventional uranium mill to be constructed in
the U.S. in over 30 years. The Piñon Ridge Mill would be designed with an
initial capacity of 500 tons per day (tpd) of ore throughput, with a design
footprint that could be expanded to 1,000 tpd if market conditions warrant and
subject to the regulatory approval process for permit modification. In addition,
the mines in the Uravan Mining District produce vanadium as a mineral associated
with uranium. The presence of vanadium in these deposits effectively lowers the
cost of uranium extraction. At historical U3O8 and V2O5 grades typical for the
region, the Piñon Ridge Mill would be designed to produce between 1.6 million
and 2.0 million pounds of U3O8 and 5 million to 8 million pounds of V2O5 per
year.

192

---

Certain permits and approvals have been obtained for the Piñon
Ridge Mill, including a Special Use Permit from Montrose County, Colorado
(September 2009) and a Radioactive Materials License (License) and air
quality permits from the State of Colorado (April 2013 and July 2013,
respectively). Non-government organizations have challenged the various
regulatory approvals, including ongoing litigation regarding the License (see
Legal and Regulatory Proceedingsbelow).

The Company continues to hold the property, defend the legal
challenges and maintain the license, permit, and other regulatory approvals in
good standing. With the acquisition by the Company of the White Mesa Mill in
2012, the Company no longer needs to construct the Piñon Ridge Mill in order to
meet its planned production for the foreseeable future. Therefore, the Company
does not intend to proceed with construction of the mill at this time, and is
pursuing the potential sale, joint venture, trade or disposition of the Piñon
Ridge Mill, as well as certain other mineral properties.

Mines

The Company acquired the US Mining Division on June 29, 2012.
Since that time, the Company had five active mining operations, the Daneros, the
Beaver and Pandora mines in the La Sal Complex in Utah, and the Arizona 1 and
Pinenut mines in Arizona. On October 17, 2012, the Company placed the Daneros
and Beaver mines on standby, pending improved market conditions, and the Pandora
mine was placed on standby in December 2012. There are ten other mines, the Tony
M, Whirlwind, Energy Queen, Rim, Van 4, Carnation, Sunday, Topaz, St. Jude and
West Sunday, which are on care and maintenance.

In 2011, Energy Fuels Arizona 1 mine received the 2010 U.S.
Department of Labors MSHA Sentinels of Safety Award in the small underground
metal mine category. In 2010, the Arizona 1 mine personnel worked a total of
56,417 injury-free hours. The Daneros mine in Utah was recognized as a runner up
with a total of 23,674 injury-free hours. The Sentinels of Safety Award
acknowledges the men and women at those mines in the United States that have
worked the most employee-hours without experiencing a lost-time injury.

There was one lost time accidents at the mining operations in
FY-2013.

Reclamation

All of the Companys mines in the U.S. are subject to closure
and reclamation liabilities. The estimate of the reclamation costs for the
various mining operations in Colorado, Utah, Arizona and Wyoming is $5.7
million. Financial bonds are in place for the total amount.

EMPLOYEES

At December 31, 2013, the Company had a total of 182 active
employees in the United States. None of the Companys employees are unionized.

In the United States, the Company also retains the services of
White Mesa Inc., an independent local native-owned company that provides the
services of 17 additional personnel to the White Mesa Mill and some mine
operations.

GOVERNMENTREGULATION

U.S. Uranium Industry

Uranium milling in the U.S. is primarily regulated by the NRC
pursuant to the Atomic Energy Act of 1954, as amended. Its primary
function is to ensure the protection of employees, the public and the
environment from radioactive materials and it also regulates most aspects of the
uranium recovery process. The NRC regulations pertaining to uranium recovery
facilities are codified in Title 10 of the Code of Federal Regulations.

On August 16, 2004, the State of Utah became an Agreement State
for the regulation of uranium mills. This means that the primary regulator for
the White Mesa Mill is now UDEQ rather than the NRC. At that time, the mills
NRC Source Material License was transferred to the State and became a
Radioactive Materials License. The State of Utah incorporates, through its own
regulations or by reference, all aspects of Title 10 pertaining to uranium
recovery facilities. The White Mesa License was due for renewal on March 31,
2007. Energy Fuels predecessor submitted its application for renewal of the
license on February 28, 2007. A draft renewal license was published for comment
by UDEQ in the 4th quarter of 2011, and is expected to be
re-published for comment in 2014. UDEQ is currently in the process of reviewing
the public comments and performing additional environmental reviews. Energy
Fuels expects that the renewed license will be issued by UDEQ by the end of FY
2014. During the period that the State is reviewing the license renewal
application, the Mill can continue to operate under its existing Radioactive
Materials License. The mills license was initially issued in 1980 and was
renewed in 1987 and 1997.

When the State of Utah became an Agreement State, it required
that a GWDP be put in place for the White Mesa Mill. The GWDP is required for
all similar facilities in the State of Utah, and specifically tailors the
implementation of the State groundwater regulations to the Mill site. The State
of Utah requires that every operating uranium mill have a GWDP, regardless of
whether or not the facility discharges to groundwater. The GWDP for the Mill was
finalized and implemented in March 2005. The GWDP required that the Mill add
over 40 additional monitoring parameters and 15 additional monitoring wells at
the site. The GWDP came up for renewal in 2010, and is currently in the renewal
process. During the review period the Mill can continue to operate under its
existing GWDP. The White Mesa Mill also maintains permit approvals for air
emissions with UDEQ, Division of Air Quality.

The State of Colorado is also an Agreement State that regulates
the licensing of uranium mills, including the proposed Piñon Ridge Mill. The
primary state requirements for a uranium mill to operate in Colorado include a
Radioactive Materials License and Air Quality Permit from the Colorado Air
Pollution Control Division of CDPHE.

Uranium mining is subject to regulation by a number of agencies
including (1) local county and municipal government agencies; (2) the applicable
state divisions responsible for mining and protecting the environment within
Utah, Colorado, Arizona and Wyoming; (3) the BLM and the USFS on public lands
under their jurisdiction; (4) the U.S. Mine Safety and Health Administration
(MSHA); (5) the EPA for radon emissions from underground mines; and (6) other
federal agencies (e.g., U.S. Fish and Wildlife Service, U.S. Army Corp. of
Engineers, DOE), where certain conditions exist. In addition, the Sheep Mountain
project will be subject to regulation under the NRC, as a uranium processing
facility and for
permanent disposal of the resulting tailings.  A review of the major permit for each mine is included above under “Mineral Projects”.

194

---

Energy Fuels is required to have export licenses issued by the NRC for its uranium exports. Such licenses are obtained by the Company as required.

Land Tenure

United States

The Company’s land holdings in the U.S. are held either by leases from the fee simple owners (private parties or the State) or unpatented mining claims located on property owned and managed by the U.S. Federal Government.  Annual fees must be
paid to maintain unpatented mining claims, but work expenditures are not required. Holders of unpatented mining claims are generally granted surface access to conduct mineral exploration and mining activities. However, additional mine permits and
plans are generally required prior to conducting exploration or mining activities on such claims.

On July 9, 2009, BLM issued a Notice of Proposed Withdrawal (“2009 Notice”) under which it proposed that a total of approximately one million acres of public lands around the Grand Canyon National Park be withdrawn from location
and entry under the Mining Law of 1872 (the “Mining Law”), subject to valid existing rights. In the 2009 Notice, BLM stated that the purpose of the withdrawal, if determined to be appropriate, would be to protect the Grand Canyon
watershed from any adverse effects of locatable hardrock mineral exploration and mining. The 2009 Notice segregated the lands from location and entry under the mining laws for up to two years to allow time for various studies and analysis, including
appropriate National Environmental Policy Act (“NEPA”) analysis.  In order to allow more time for BLM to complete its NEPA analysis, the U.S. Department of the Interior (the “DOI”) published Public Land Order
7773 on June 21, 2011, which effected a six-month emergency withdrawal of the area. The emergency withdrawal prevented the lands from opening to location and entry under the Mining Law upon expiration of the two-year segregation while the DOI
completed the decision–making process on the proposed withdrawal.  The emergency withdrawal was effective July 21, 2011 to January 20, 2012. During the two-year segregation and six month emergency withdrawal, the BLM, along with its
cooperating agencies, completed various studies and analyses of resources in the withdrawal area, including an EIS under NEPA. These studies and analyses were undertaken to provide the basis for the final decision regarding whether or not to proceed
with the proposed withdrawal or to select an alternative action. Based on this analysis, on January 9, 2012, the DOI announced its final decision to withdraw from location and entry under the Mining Law, subject to valid existing rights, the total
of approximately one million acres of lands originally proposed in the 2009 Notice (the “Withdrawn Lands”), for a 20-year period. Lawsuits challenging this decision have been filed by various industry groups and interested
parties.

No new mining claims may be filed on the Withdrawn Lands and no new plans of operations may be approved, other than plans of operations on mining claims that were valid at the time of withdrawal and that remain valid at the time of plan approval.
Whether or not a mining claim is valid must be determined by a mineral examination conducted by BLM or USFS, as applicable. The mineral examination, which involves an economic evaluation of a project, must demonstrate the existence of a locatable
mineral resource and that the mineral resource constitutes the discovery of a valuable mineral deposit.

195

---

All of the Company’s Arizona Strip properties, with the exception of its Moonshine Springs property and certain exploration properties held by the Company’s subsidiary, Arizona Strip Partners LLC, are located within the Withdrawn Lands.
BLM is currently undertaking a mineral examination on the Company’s EZ Complex, in conjunction with its review of the Company’s proposed PO for that project.  Mineral
examinations are not required for the Company’s Arizona 1 and Pinenut mines, which have previously approved POs and are currently undergoing mining activities, or have undergone mining activities before and after the Withdrawal.  Although the
Company’s Canyon Project also has an approved PO, and a mineral examination is not required, the USFS performed a mineral examination on that project in 2012 and concluded that the Canyon Project’s claims constitute valid existing
rights, and that mining may proceed on the Canyon Project.

The Company believes that all of its material Arizona Strip projects within the Withdrawn Lands are on valid mining claims that will each withstand a mineral examination. However, market conditions may postpone or prevent the performance of mineral
examinations on certain properties and, if a mineral examination is performed on a property, there can be no guarantee that the mineral examination would not result in one of more of the Company’s mining claims being considered invalid, which
could prevent a project from proceeding.

RISKFACTORS


There are a number of factors that could negatively affect
Energy Fuels business and the value of its securities, including the factors
listed below. The following information pertains to the outlook and conditions
currently known to Energy Fuels that could have a material impact on the
financial condition of Energy Fuels. Other factors may arise in the future that
are currently not foreseen by management of Energy Fuels that may present
additional risks in the future. Current and prospective security holders of
Energy Fuels should carefully consider these risk factors.

URANIUM ANDVANADIUMPRICEFLUCTUATIONS

The results of the Companys operations are significantly
affected by the market price of uranium and vanadium which are cyclical and
subject to substantial price fluctuations. The Companys earnings and operating
cash flow are and will be particularly sensitive to the change in the long and
short term market price of uranium and vanadium. Among other factors, these
prices also affect the value of the Companys reserves and inventories and the
market price of the Companys common shares.

Market prices are affected by numerous factors beyond the
Companys control. With respect to uranium, such factors include, among others:
demand for nuclear power, political and economic conditions in uranium producing
and consuming countries, public and political response to a nuclear incident,
reprocessing of used reactor fuel, the re-enrichment of depleted uranium tails
and the enricher practice of underfeeding, sales of excess civilian and military
inventories (including from the dismantling of nuclear weapons and from the
build-up of Japanese utility uranium inventories as a result of the Fukushima
incident) by governments and industry participants, uranium supply, including
the supply from other secondary sources and production levels and costs of
production. With respect to vanadium, such factors include, among others: demand
for steel, political and economic conditions in vanadium producing and consuming
countries, world production levels and costs of production. Other factors
include levels of supply and demand for a broad range of industrial products,
substitution of new or different products in critical applications for the
Companys existing products, expectations with respect to the rate of inflation,
the relative strength of the US dollar and of certain other currencies, interest
rates, global or regional political or economic crises and sales of uranium and
vanadium by holders in response to such factors. If prices should decline below
the Companys cash costs of production and remain at such levels for any
sustained period, the Company may determine that it is not economically feasible
to continue commercial production at any or all of the Companys mines or other
facilities and may also be required to look for alternatives other than cash
flow to maintain the Companys liquidity until prices recover. The Companys
expected levels of production and business activity are dependent on the
Companys and industrys expectations of uranium and vanadium prices, which may
not be realized or may change. In the event the Company concludes that a significant  deterioration in expected future uranium prices has occurred, the Company will  assess whether an impairment allowance is necessary which, if required, could  be material.

The recent fluctuations in the price of many commodities is an
example of a situation over which the Company has no control and which could
materially adversely affect the Company in a manner for which it may not be able
to compensate. There can be no assurance that the price of any minerals produced
from the Companys properties will be such that any deposits can be mined at a
profit.

The Companys profitability is directly related to the market
price of uranium and vanadium produced. The Company may from time to time
undertake commodity and currency hedging programs, with the intention of
maintaining adequate cash flows and profitability to contribute to the long term
viability of the business. The Company anticipates selling forward in the
ordinary course of business if, and when, the Company has sufficient assets and
production to support forward sale arrangements. There are, however, risks
associated with forward sale programs. If the Company does not have sufficient
production to meet its forward sale commitments, it may have to buy or borrow (for later delivery back from production) sufficient product in the spot market to deliver under the forward sales contracts, possibly at higher prices than provided for
in the forward sales contracts.  Although the Company employs various pricing mechanisms within its sales contracts to manage its exposure to price fluctuations, there can be no assurance that such mechanisms will be successful.

197

GLOBALECONOMICDOWNTURN

In the event of a continued general economic downturn or a recession, there can be no assurance that the business, financial condition and results of operations of the Company would not be materially adversely affected.  Current global financial
conditions have been subject to increased volatility, and numerous commercial and financial enterprises have either gone into bankruptcy or creditor protection or have had to be rescued by governmental authorities. Access to public financing has
been negatively impacted by sub-prime mortgage defaults in the United States, the liquidity crisis affecting the asset-backed commercial paper and collateralized debt obligation markets, massive investment losses by banks with resultant
recapitalization efforts and a deterioration in the global economy.  Although economic conditions have shown improvement in recent years, the recovery from the recession has been slow in various jurisdictions including in Europe and the United
States and has been impacted by various ongoing factors including sovereign debt levels and high levels of unemployment, which continue to impact commodity prices and which have resulted in high volatility in currencies and global debt and stock
markets.

These factors may impact the Company’s ability to obtain equity, debt or bank financing on terms commercially reasonable to the Company, or at all. Additionally, these factors, as well as other related factors, may cause decreases in asset
values that are deemed to be other than temporary, which may result in impairment losses.  If these increased levels of volatility and market turmoil continue, or there is a material deterioration in general business and economic conditions, the
Company’s operations could be adversely impacted and the trading price of the Company’s securities could continue to be adversely affected.

MARKETPRICE OFSHARES

Securities of mining companies have experienced substantial volatility in the past, often based on factors unrelated to the financial performance or prospects of the companies involved.  These factors include macroeconomic conditions in North
America and globally, and market perceptions of the attractiveness of particular industries. The price of the Company’s securities is also likely to be significantly affected by short-term changes in uranium and vanadium prices, changes in
industry forecasts of uranium and vanadium prices, other mineral prices, currency exchange fluctuation, or in its financial condition or results of operations as reflected in its periodic earnings reports.  Other factors unrelated to the performance
of the Company that may have an effect on the price of the securities of the Company include the following: the extent of analytical coverage available to investors concerning the business of the Company may be limited if investment banks with
research capabilities do not follow the Company’s securities; lessening in trading volume and general market interest in the Company’s securities may affect an investor's ability to trade significant numbers of securities of the Company;
the size of the Company’s public float and its inclusion in market indices may limit the ability of some institutions to invest in the Company's securities; and a substantial decline in the price of the securities of the Company that persists
for a significant period of time could cause the Company’s securities to be delisted from an exchange, further reducing market liquidity.  If an active market for the securities of the Company does not continue, the liquidity of an investor's
investment may be limited and the price of the securities of the Company may decline. If an active market does not exist, investors may lose their entire investment in the Company. As a result of any of these factors, the market price of the
securities of the Company at any
given point in time may not accurately reflect the long-term value of the Company.  Securities class-action litigation often has been brought against companies following periods of volatility in the market price of their securities. The Company may
in the future be the target of similar litigation. Securities litigation could result in substantial costs and damages and divert management's attention and resources.

other matters.  Compliance with such laws and regulations has increased the costs of exploring, drilling, developing, constructing, operating and closing the Company’s mines and processing facilities. It is possible that, in the future, the
costs, delays and other effects associated with such laws and regulations may impact the Company’s decision as to whether to operate existing mines, or, with respect to exploration and development properties, whether to proceed with
exploration or development, or that such laws and regulations may result in the Company incurring significant costs to remediate or decommission properties that do not comply with applicable environmental standards at such time. The Company expends
significant financial and managerial resources to comply with such laws and regulations.  The Company anticipates it will have to continue to do so as the historic trend toward stricter government regulation may continue. There can be no assurance
that future changes in applicable laws and regulations will not adversely affect the operations or financial condition of the Company.  New laws and regulations, amendments to existing laws and regulations or more stringent implementation of
existing laws and regulations, including through stricter license and permit conditions, could have a material adverse impact on the Company, increase costs, cause a reduction in levels of, or suspension of, production and/or delay or prevent the
development of new mining properties.

Mining is subject to potential risks and liabilities associated with pollution of the environment and the disposal of waste products occurring as a result of mineral exploration, mining and production. Environmental liability may result from mining
activities conducted by others prior to the Company’s ownership of a property. Failure to comply with applicable laws, regulations and permitting requirements may result in enforcement actions. These actions may result in orders issued by
regulatory or judicial authorities causing operations to cease or be curtailed, and may include corrective measures requiring capital expenditures, installation of additional equipment or remedial actions.  Companies engaged in uranium exploration
operations may be required to compensate others who suffer loss or damage by reason of such activities and may have civil or criminal fines or penalties imposed for violations of applicable laws or regulations. Should the Company be unable to fully
fund the cost of remedying an environmental problem, it might be required to suspend operations or enter into interim compliance measures pending completion of the required remedy, which could have a material adverse effect on the Company. To the
extent that the Company is subject to uninsured environmental liabilities, the payment of such liabilities would reduce otherwise available earnings and could have a material adverse effect on the Company. In addition, the Company does not have
coverage for certain environmental losses and other risks as such coverage cannot be purchased at a commercially reasonable cost. Compliance with applicable environmental laws and regulations requires significant expenditures and increases mine
development and operating costs

Worldwide demand for uranium is directly tied to the demand for electricity produced by the nuclear power industry, which is also subject to extensive government regulation and policies. The development of mines and related facilities is contingent upon governmental
approvals that are complex and time consuming to obtain and which, depending
upon the location of the project, involve multiple governmental agencies. The
duration and success of such approvals are subject to many variables outside the
Companys control. Any significant delays in obtaining or renewing such permits
or licenses in the future could have a material adverse effect on the Company.
In addition, the international marketing of uranium is subject to governmental
policies and certain trade restrictions, such as those imposed by the suspension
agreement between the United States and Russia. Changes in these policies and
restrictions may adversely impact the Companys business.

PUBLICACCEPTANCE OFNUCLEARENERGY ANDCOMPETITION
FROMOTHERENERGYSOURCES

Growth of the uranium and nuclear industry will depend upon
continued and increased acceptance of nuclear technology as a means of
generating electricity. Because of unique political, technological and
environmental factors that affect the nuclear industry, including the risk of a
nuclear incident, the industry is subject to public opinion risks that could
have an adverse impact on the demand for nuclear power and increase the
regulation of the nuclear power industry. Nuclear energy competes with other
sources of energy, including oil, natural gas, coal and hydro-electricity. These
other energy sources are to some extent interchangeable with nuclear energy,
particularly over the longer term. Sustained lower prices of oil, natural gas,
coal and hydroelectricity may result in lower demand for uranium concentrates.
Technical advancements in renewable and other alternate forms of energy, such as
wind and solar power, could make these forms of energy more commercially viable
and put additional pressure on the demand for uranium concentrates.

URANIUMINDUSTRYCOMPETITION ANDINTERNATIONALTRADERESTRICTIONS

The international uranium industry, including the supply of
uranium concentrates, is competitive. The Company markets uranium in direct
competition with supplies available from a relatively small number of uranium
mining companies, from excess inventories, including inventories made available
from decommissioning of nuclear weapons, from reprocessed uranium and plutonium,
from used reactor fuel, and from the use of excess Russian enrichment capacity
to re-enrich depleted uranium tails held by European enrichers in the form of
UF6. The supply of uranium from Russia and from certain republics of the former
Soviet Union is, to some extent, impeded by a number of international trade
agreements and policies. These agreements and any similar future agreements,
governmental policies or trade restrictions are beyond the control of the
Company and may affect the supply of uranium available in the United States and
Europe, which are the largest markets for uranium in the world.

ABILITY TOMAINTAINOBLIGATIONSUNDERDEBENTURES ANDOTHERDEBT

The Company may from time to time enter into arrangements to
borrow money in order to fund its operations and expansion plans, and such
arrangements may include covenants that restrict its business in some way.
Events may occur in the future, including events out of the Companys control
that would cause the Company to fail to satisfy its obligations under its
existing Debentures or other debt instruments. In such circumstances, or if the
Company were to default on its obligations under the Debentures or other debt
instruments, the amounts drawn under the Companys debt agreements may become
due and payable before the agreed maturity date, and the Company may not have
the financial resources to repay such amounts when due.

Further, although most, but not all, of the Companys
reclamation obligations are bonded, and cash and other assets of the Company
have been reserved to secure a portion but not all of this bonded amount, to the
extent the bonded amounts are not fully collateralized, the Company will be
required to come up with additional cash to perform its reclamation obligations
when they occur. In addition, the bonding
companies have the right to require increases in collateral at any time upon 30-days’ notice to the Company, failure of which would constitute a default under the bonds.  In such circumstances, the Company may not have the financial resources
to perform such reclamation obligations or to increase such collateral when due.

200

ADDITIONALFUNDINGREQUIREMENTS

The Company may need additional financing in connection with the implementation of its business and strategic plans from time to time.  The exploration and development of mineral properties and the ongoing operation of mines, requires a substantial
amount of capital and may depend on the Company’s ability to obtain financing through joint ventures, debt financing, equity financing or other means. The Company may accordingly have further capital requirements to take advantage of further
opportunities or acquisitions.  The Company’s financial condition, general market conditions, volatile uranium and vanadium markets, volatile interest rates, a claim against the Company, a significant disruption to the Company’s business
or operations or other factors may make it difficult to secure financing necessary for the expansion of mining activities or to take advantage of opportunities for acquisitions.  Further, continuing volatility in the credit markets may increase
costs associated with debt instruments due to increased spreads over relevant interest rate benchmarks, or affect the ability of the Company, or third parties it seeks to do business with, to access those markets. There is no assurance that the
Company will be successful in obtaining required financing as and when needed on acceptable terms, if at all.

DILUTION FROMFURTHEREQUITYFINANCING

If the Company raises additional funding by issuing additional equity securities or securities convertible, exercisable or exchangeable for equity securities, such financing may substantially dilute the interests of shareholders of the Company and
reduce the value of their investment.

NATURE OFEXPLORATION ANDDEVELOPMENT,EXPANSIONPROJECTS ANDRESTARTINGPROJECTS

The exploration and development of mineral deposits, the expansion of projects and restarting projects involves significant financial risks.  Development of any of the exploration properties in which the Company has an interest will only follow upon
obtaining satisfactory exploration results. The exploration and development of mineral deposits involve significant financial risks over an extended period of time, which even a combination of careful evaluation, experience and knowledge may not
eliminate. While discovery of a mine may result in substantial rewards, few properties which are explored are ultimately developed into producing mines.  Major expenses may be required to establish mineral resources and mineral reserves by drilling
and to construct mining and processing facilities at a site. It is impossible to ensure that the current or proposed exploration programs on the Company’s mineral resource properties will result in a profitable commercial mining operation.

Whether a mineral deposit will be commercially viable depends on a number of factors, which include, among other things: the accuracy of reserve estimates; the particular attributes of the deposit, such as its size and grade; ability to economically
recover commercial quantities of the minerals; proximity to infrastructure; financing costs and governmental regulations, including regulations relating to prices, taxes, royalties; infrastructure; land use; importing and exporting and environmental
protection. Development, expansion and restarting projects are also subject to the successful completion of engineering studies, issuance of necessary governmental permits and availability of adequate financing, and that engineering and construction
timetables and capital costs for the Company’s development and expansion projects and restarting projects on standby, are not incorrectly estimated or affected by unforeseen circumstances. The effect of these factors cannot be accurately
predicted, but the combination of these factors may result in the Company not receiving an adequate return on invested capital.

201

---

It is possible that actual costs and economic returns of current and new mining operations may differ materially from the Company’s best estimates. It is not unusual in the mining industry for new mining operations to experience unexpected
problems during the start-up phase, take much longer than originally anticipated to bring into a producing phase, and to require more capital than anticipated.

THECOMPANY’SMINERALRESERVES ANDRESOURCES AREESTIMATES

Mineral reserves and resources are statistical estimates of mineral content, based on limited information acquired through drilling and other sampling methods, and require judgmental interpretations of geology. Successful extraction requires safe
and efficient mining and processing. The Company’s mineral reserves and resources are estimates, and no assurance can be given that the estimated resources are accurate or that the indicated level of uranium or vanadium will be produced. Such
estimates are, in large part, based on interpretations of geological data obtained from drill holes and other sampling techniques.  Actual mineralization or formations may be different from those predicted. Further, it may take many years from the
initial phase of drilling before production is possible, and during that time the economic feasibility of exploiting a discovery may change.

Mineral reserve and resource estimates for properties that have not commenced production are based, in many instances, on limited and widely spaced drill hole information, which is not necessarily indicative of the conditions between and around
drill holes.  Accordingly, such mineral resource estimates may require revision as more drilling information becomes available or as actual production experience is gained. It should not be assumed that all or any part of the Company’s mineral
resources constitute or will be converted into reserves. Market price fluctuations of uranium or vanadium as applicable, as well as increased production and capital costs or reduced recovery rates, may render the Company’s proven and probable
reserves unprofitable to develop at a particular site or sites for periods of time or may render mineral reserves containing relatively lower grade mineralization uneconomic.

ENVIRONMENTALREGULATORYREQUIREMENTS ANDRISK

The Company is required to comply with environmental protection laws and regulations and permitting requirements promulgated by federal agencies and various states and counties in which the Company operates, in connection with mining and milling
operations. The uranium industry is subject not only to the worker health and safety and environmental risks associated with all mining businesses, but also to additional risks uniquely associated with uranium mining and milling. The Company expends
significant resources, both financial and managerial, to comply with these laws and regulations. The possibility of more stringent regulations exists in the areas of worker health and safety, storage of hazardous materials, standards for heavy
equipment used in mining or milling, the disposition of wastes, the decommissioning and reclamation of exploration, mining, milling and in-situ sites, climate change and other environmental matters, each of which could have a material adverse effect
on the cost or the viability of a particular project.

The Company cannot predict what environmental legislation, regulations or policies will be enacted or adopted in the future or how future laws and regulations will be administered or interpreted. The recent trend in environmental legislation and
regulation is generally toward stricter standards, and this trend is likely to continue in the future.  This recent trend includes, without limitation, laws and regulations relating to air and water quality, mine reclamation, waste handling and
disposal, the protection of certain species and the preservation of certain lands. These regulations may require the acquisition of permits or other authorizations for certain activities. These laws and regulations may also limit or prohibit
activities on certain lands.  Compliance with more stringent laws and regulations, as well as potentially more vigorous enforcement policies, stricter interpretation of existing laws and stricter permit and license
conditions, may necessitate significant capital outlays, may materially affect the Company’s results of operations and business or may cause material changes or delays in the Company’s intended activities. There can be no assurance of
the Company’s continued compliance or ability to meet stricter environmental laws and regulations and permit or license conditions. Delays in obtaining permits and licenses could impact expected production levels or increases in expected
production levels.

202

---

The Company’s operations may require additional analysis in the future including environmental, cultural and social impact and other related studies.  Certain activities require the submission and approval of environmental impact assessments.
The Company cannot provide assurance that it will be able to obtain or maintain all necessary permits that may be required to continue operations or exploration and development of its properties or, if feasible, to commence construction or operation
of mining facilities at such properties on terms that enable operations to be conducted at economically justifiable costs. If the Company is unable to obtain or maintain, licenses, permits or other rights for development of its properties, or
otherwise fails to manage adequately future environmental issues, its operations could be materially and adversely affected.

OPPOSITION TOMINING MAYDISRUPTBUSINESSACTIVITY

In recent years, governmental and non-governmental agencies, individuals, communities and courts have become more vocal and active with respect to their opposition of certain mining and business activities including with respect to the commencement
and recommencement of mining at the Company's mines, such as the Canyon Project. This opposition may take on forms such as road blockades, applications for injunctions seeking work stoppages, refusals to grant access to lands or to sell lands on
commercially viable terms, lawsuits for damages or to revoke or modify licenses and permits, issuances of unfavourable laws and regulations, and other rulings contrary to an entity’s interest.  These actions can occur in response to current
activities or in respect of mines that are decades old. Opposition to the Company’s business activities are beyond the Company’s control.  Any opposition to the Company’s business activities may cause a disruption to the
Company’s business activities and may result in increased costs and this could have a material adverse effect on the Company’s business and financial condition.

COMPETITION FORPROPERTIES ANDEXPERIENCEDEMPLOYEES

The Company competes with other mining companies and individuals for capital, mining interests on exploration properties and undeveloped lands, acquisitions of mineral resources and reserves and other mining assets, which may increase its cost of
acquiring suitable claims, properties and assets, and the Company also competes with other mining companies to attract and retain key executives and employees. There can be no assurance that the Company will continue to be able to compete
successfully with its competitors in acquiring such properties and assets or in attracting and retaining skilled and experienced employees. The mining industry has been impacted by increased worldwide demand for critical resources such as input
commodities, drilling equipment, tires and skilled labour, and these shortages have caused unanticipated cost increases and delays in delivery times, thereby impacting operating costs, capital expenditures and production schedules.

LITIGATION ANDOTHERLEGALPROCEEDINGS

The Company is subject to litigation and other legal proceedings arising in the normal course of business and may be involved in disputes with other parties in the future which may result in litigation. The causes of potential future litigation and
legal proceedings cannot be known and may arise from, among other things, business activities, environmental laws, volatility in stock price or failure to comply with disclosure obligations. The results of litigation and proceedings cannot be
predicted with certainty, and may include potential injunctions pending the outcome of such litigation and proceedings.  If the
Company is unable to resolve these disputes favourably, it may have a material adverse impact on the Company’s financial performance, cash flow and results of operations.

DECOMMISSIONING ANDRECLAMATION

As owner and operator of the White Mesa Mill and numerous uranium and uranium/vanadium mines located in the United States and certain exploration properties, and for so long as the Company remains an owner thereof, the Company is obligated to
eventually reclaim or participate in the reclamation of such properties. Most, but not all, of the Company’s reclamation obligations are bonded, and cash and other assets of the Company have been reserved to secure a portion but not all of
this bonded amount. Although the Company’s financial statements will record a liability for the asset retirement obligation, and the bonding requirements are generally periodically reviewed by applicable regulatory authorities, there can be no
assurance or guarantee that the ultimate cost of such reclamation obligations will not exceed the estimated liability to be provided on the Company’s financial statements.  Further, to the extent the bonded amounts are not fully
collateralized, the Company will be required to come up with additional cash to perform its reclamation obligations when they occur.

Decommissioning plans for the Company’s properties have been filed with applicable regulatory authorities. These regulatory authorities have accepted the decommissioning plans in concept, not upon a detailed performance forecast, which has not
yet been generated. As the Company’s properties approach or go into decommissioning, further regulatory review of the decommissioning plans may result in additional decommissioning requirements, associated costs and the requirement to provide
additional financial assurances. It is not possible to predict what level of decommissioning and reclamation (and financial assurances relating thereto) may be required in the future by regulatory authorities.

TECHNICALINNOVATION ANDOBSOLESCENCE

Requirements for the Company’s products and services may be affected by technological changes in nuclear reactors, enrichment and used uranium fuel reprocessing.  These technological changes could reduce the demand for uranium.  In addition,
the Company’s competitors may adopt technological advancements that give them an advantage over the Company.

PROPERTYTITLERISK

The Company has investigated its rights to explore and exploit all of its material properties and, to the best of its knowledge, those rights are in good standing. However, no assurance can be given that such rights will not be revoked, or
significantly altered, to the Company’s detriment. There can also be no assurance that the Company’s rights will not be challenged or impugned by third parties, including by local governments.

The validity of unpatented mining claims on U.S. public lands is sometimes difficult to confirm and may be contested. Due to the extensive requirements and associated expense required to obtain and maintain mining rights on U.S. public lands, the
Company's U.S. properties are subject to various title uncertainties which are common to the industry or the geographic location of such claims, with the attendant risk that there may be defects in its title. In addition, the Secretary of the
Interior has withdrawn certain lands around the Grand Canyon National Park from location and entry under the Mining Laws.  All of the Company’s material Arizona Strip properties are located on these withdrawn lands.  No new mining claims may
be filed on the withdrawn lands and no new plans of operations may be approved, other than plans of operations on mining claims that were valid at the time of withdrawal and that remain valid at the time of plan approval.  Whether or not a mining
claim is valid must be determined by a mineral examination conducted by BLM or USFS, as applicable. The mineral examination, which involves an
economic evaluation of a project, must demonstrate the existence of a locatable mineral resource and that the mineral resource constitutes discovery of a valuable mineral deposit. The Company believes that all of its material Arizona Strip projects
are on valid mining claims that would withstand a mineral examination. Further, the Company’s Arizona 1 and Pinenut mines have approved plans of operations which, absent modification, would not require a mineral examination. Although the
Company’s Canyon Project also has an approved plan of operations, which, absent modification, would not require a mineral examination, the USFS performed a mineral examination at that mine in 2012, and concluded that the underlying mining
claims were valid existing rights.  However, market conditions may postpone or prevent the performance of mineral examinations on certain other properties and, if a mineral examination is performed on a property, there can be no guarantee that the
mineral examination would not result in one or more of the Company’s mining claims being considered invalid, which could prevent a project from proceeding.

204

FOREIGNCURRENCYRISKS

The Company’s operations are subject to foreign currency fluctuations.  The Company’s operating expenses and revenues are primarily incurred in U.S. dollars, while some of its cash balances and expenses are measured in Canadian dollars.
The fluctuation of the Canadian dollar in relation to the U.S. dollar will consequently have an impact upon the profitability of the Company and may also affect the value of the Company’s assets and shareholders’ equity.

POST-ACQUISITIONSUCCESS

The Company may not realize the anticipated benefits of acquiring the US Mining Division or completing the Strathmore Acquisition, due to integration and operational challenges, and to decreases in commodity prices that have required the Company to
place a number of acquired mines on standby and to defer permitting and development activities on certain other acquired assets, until market conditions warrant otherwise.  The success of the Company following those acquisitions will depend in large
part on the success of the Company’s management in integrating the US Mining Division and the Strathmore assets into the Company. The failure of the Company to achieve such integration and to mine or advance such assets could result in the
failure of the Company to realize the anticipated benefits of the Denison Acquisition and Strathmore Acquisition and could impair the results of operations, profitability and financial results of the Company.

PRODUCTIONESTIMATES ANDPRODUCTIONEFFICIENCY

The Company may from time to time prepare estimates of future production or increases in production for particular operations, or relating to the Company’s ability to increase production in response to increases in commodity prices, as market
conditions warrant or otherwise. No assurance can be given that any such production estimates will be achieved nor can assurance be given that production or production increases will be achieved in a cost effective or timely manner. Failure to
achieve production estimates or failure to achieve production in a cost effective or timely manner could have an adverse impact on the Company’s future cash flows, earnings, results of operations and financial condition. These production
estimates are based on, among other things, the following factors: the accuracy of mineral reserve estimates; the accuracy of assumptions regarding ground conditions and physical characteristics of ores, such as hardness and presence or absence of
particular metallurgical characteristics; the accuracy of estimated rates and costs of mining and processing; assumptions as to future commodity prices; assumptions relating to changes in laws, regulations or policies, or lack thereof, that could
impact the cost and time required to obtain regulatory approvals, licenses and permits; assumptions relating to obtaining required licenses and permits in a timely manner, including the time required to satisfy environmental analyses, consultations
and public input processes; assumptions relating to challenges to or delays in the licensing
and permitting process; and assumptions regarding any appeals or lack thereof, or injunctions or lack thereof, relating to any approvals, licenses or permits.

205

---

The Company’s actual production may vary from estimates for a variety of reasons, including, among others: actual ore mined varying from estimates of grade, tonnage, dilution and metallurgical and other characteristics; short term operating
factors relating to the mineral reserves, such as the need for sequential development of ore bodies and the processing of new or different ore grades; risk and hazards associated with mining; natural phenomena, such as inclement weather conditions,
underground floods, earthquakes, pit wall failures and cave-ins; unexpected labor shortages or strikes; varying conditions in the commodities markets; and delays in obtaining or denial, challenges or appeals of regulatory approvals, licenses and
permits or renewals of existing approvals, licenses or permits.

DEPENDENCE ONISSUANCE OFMILLLICENCEAMENDMENTS ANDRENEWALS

The Company maintains regulatory licenses and permits in order to operate its White Mesa Mill, all of which are subject to renewal from time to time and are required in order for the Company to operate in compliance with applicable laws and
regulations.  In addition, depending on the Company’s business requirements, it may be necessary or desirable to seek amendments to one or more of its licenses or permits from time to time. While the Company has been successful in renewing its
licenses and permits on a timely basis in the past and in obtaining such amendments as have been necessary or desirable, there can be no assurance that such license and permit renewals and amendments will be issued by applicable regulatory
authorities on a timely basis or at all in the future.

MINING,MILLING ANDINSURANCE

The operations of the Company are subject to all of the hazards and risks normally incidental to exploration, development and mining of mineral properties, and milling, including: environmental hazards; industrial accidents; labor disputes,
disturbances and unavailability of skilled labor; encountering unusual or unexpected geologic formations; rock bursts, pressures, cave-ins, flooding; periodic interruptions due to inclement or hazardous weather conditions; technological and
processing problems, including unanticipated metallurgical difficulties, ground control problems, process upsets and equipment malfunctions; the availability and/or fluctuations in the costs of raw materials and consumables used in the
Company’s production processes; the ability to procure mining equipment and operating supplies in sufficient quantities and on a timely basis; and other mining, milling and processing risks, as well as risks associated with the Company’s
dependence on third parties in the provision of transportation and other critical services. Many of the foregoing risks and hazards could result in damage to, or destruction of, the Company’s mineral properties or processing facilities,
personal injury or death, environmental damage, delays in or interruption of or cessation of production from the Company’s mines or processing facilities or in its exploration or development activities, delay in or inability to receive
regulatory approvals to transport its uranium concentrates, or costs, monetary losses and potential legal liability and adverse governmental action.  In addition, due to the radioactive nature of the materials handled in uranium mining and
processing, additional costs and risks are incurred by the Company on a regular and ongoing basis.

While the Company may obtain insurance against certain risks in such amounts as it considers adequate, the nature of these risks are such that liabilities could exceed policy limits or could be excluded from coverage. There are also risks against
which the Company cannot insure or against which it may elect not to insure. The potential costs which could be associated with any liabilities not covered by insurance or in excess of insurance coverage or compliance with applicable laws and
regulations may cause substantial delays and require significant capital outlays, adversely affecting the future earnings, financial position and competitive position of the Company. No assurance can be given that such insurance will continue to
be available or will be available at economically feasible premiums or that it will provide sufficient coverage for losses related to these or other risks and hazards. This lack of insurance coverage could result in material economic harm to the
Company.

206

REPLACEMENT OFMINERALRESERVES ANDRESOURCES ANDAVAILABILITY OFALTERNATEFEEDMATERIALS

The Company’s mineral reserves and resources at its Roca Honda, Arizona Strip, EZ Complex, Sage Plain, Henry Mountains, Daneros, Sheep Mountain, Gas Hills, Juniper Ridge, Whirlwind, and La Sal
projects are the Company’s primary sources (and potential sources) of uranium concentrates.  Unless other mineral reserves and resources are discovered or extensions to existing ore bodies are found, the Company’s sources of production
for uranium concentrates will decrease over time as its current mineral reserves and resources are depleted. There can be no assurance that the Company’s future exploration, development and acquisition efforts will be successful in
replenishing its mineral reserves and resources. In addition, while the Company believes that many of its properties will eventually be put into production, there can be no assurance that they will be or that they will be able to replace current
production.

The Company also produces uranium from processing alternate feed materials at its White Mesa Mill. There can be no assurance that additional sources of alternate feed materials will be forthcoming in the future on commercially acceptable terms or
otherwise, or that the Company will be successful in receiving all required regulatory approvals, licenses and permits on a timely basis to allow for the receipt and processing of any such alternate feed materials.

CREDITRISK

The Company’s sales of uranium and vanadium products expose Energy Fuels to the risk of non-payment.  The Company manages this risk by monitoring the credit worthiness of its customers and requiring pre-payment or other forms of payment
security from customers with an unacceptable level of credit risk.

DEPENDENCE ONKEYPERSONNEL ANDQUALIFIED ANDEXPERIENCEDEMPLOYEES

The Company’s success will largely depend on the efforts and abilities of certain senior officers and key employees, some of which are approaching retirement.  Certain of these individuals have significant experience in the uranium industry.
The number of individuals with significant experience in this industry is small. While the Company does not foresee any reason why such officers and key employees will not remain with the Company, other than through retirement, if for any reason
they do not, the Company could be adversely affected. The Company has not purchased key man life insurance for any of these individuals, other than for the Chief Executive Officer.

The Company’s success will also depend on the availability of qualified and experienced employees to work in the Company’s operations and the Company’s ability to attract and retain such employees. The number of individuals with
relevant mining and operational experience in this industry is small.

DISCLOSURE ANDINTERNALCONTROLS

Internal controls over financial reporting are procedures designed to provide reasonable assurance that transactions are properly authorized, assets are safeguarded against unauthorized or improper use, and transactions are properly recorded and
reported.  Disclosure controls and procedures are designed to ensure that information required to be disclosed by a company in reports filed with securities regulatory
agencies is recorded, processed, summarized and reported on a timely basis and is accumulated and communicated to a company’s management, including its chief executive officer and chief financial officer, as appropriate, to allow timely
decisions regarding required disclosure.  A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance with respect to the reliability of reporting, including financial reporting and financial
statement preparation.

207

---

DEPENDENCE ONBUSINESSPARTNERS,GOVERNMENT ANDTHIRDPARTYCONSENTS

The Company has a number of joint ventures and other business relationships relating to its properties and projects, including key projects, such as the Roca Honda and Gas Hills projects, which can restrict the ability of the Company to act
unilaterally with respect to those projects in certain circumstances. There can be no assurances that the Company will be able to maintain relationships with its joint venture and business partners to allow for satisfactory permitting, development,
mining or milling relating to any such projects. The Company’s operations are also dependent from time to time on receiving government and other third party consents and approvals. There can be no assurances that all such consents and
approvals will be forthcoming when required.

CONFLICTS OFINTEREST

Some of the directors of the Company are also directors of other companies that are similarly engaged in the business of acquiring, exploring and developing natural resource properties. Such associations may give rise to conflicts of interest from
time to time. In particular, one of the consequences will be that corporate opportunities presented to a director of the Company may be offered to another company or companies with which the director is associated, and may not be presented or made
available to the Company. The directors of the Company are required by law to act honestly and in good faith with a view to the best interests of the Company, to disclose any interest which they may have in any project or opportunity of the Company,
and to abstain from voting on such matter. Conflicts of interest that arise will be subject to and governed by the procedures prescribed in the Company’s Code of Ethics and by the Business Corporations Act (Ontario).

LABORRELATIONS

None of the Company’s operations directly employ unionized workers who work under collective agreements. However, there can be no assurance that employees of the Company or its contractors do not become unionized in the future, which may
impact mill and mining operations.  Any lengthy work stoppages may have a material adverse impact on the Company’s future cash flows, earnings, results of operations and financial condition.

INFRASTRUCTURE

Mining, processing, development and exploration activities depend, to a substantial degree, on adequate infrastructure. Reliable roads, bridges, power sources and water supply are important determinants affecting capital and operating costs. The
Company considers the existing infrastructure to be adequate to support its proposed operations. However, unusual or infrequent weather phenomena, sabotage, government or other interference in the maintenance or provision of such infrastructure
could adversely affect the operations, financial condition and results of operations of the Company.

DIVIDENDS


The Company has not paid dividends in the past and it does not
expect to pay dividends in the near future. Any earnings generated will be
dedicated to finance further growth. The Board of Directors of the Company will
determine if and when dividends will be declared and paid in the future based on
the Companys financial position at the relevant time.

DESCRIPTION OFCAPITALSTRUCTURE


GENERALDESCRIPTION OFCAPITALSTRUCTURE

The authorized capital of the Company consists of an unlimited
number of Common Shares, an unlimited number of Preferred Shares issuable in
series, and an unlimited number Series A Preferred Shares.

The holders of Common Shares are entitled to vote, to receive
dividends and to receive, subject to the right of holders of any other class of
shares, the remaining property of the Company upon liquidation, dissolution or
winding up of the Company. The Preferred Shares issuable in series will have the
rights, privileges, restrictions and conditions assigned to the particular
series upon the board of directors of the Company approving their issuance,
subject to the Companys Articles of Incorporation. The Series A Preferred
Shares are non-redeemable, non-callable, non-voting and do not have a right to
dividends.

As of December 31, 2013, there were 19,622,171 Common Shares
issued and outstanding (not including 20,920 treasury shares (the Treasury
Shares) held by a subsidiary of the Company. See Treasury Shares
below). As of the date hereof, the Company had an aggregate of 19,683,472 Common

RIGHTSPLAN

A shareholder rights plan (the Rights Plan) was
approved by the Board of Directors on February 3, 2009 and adopted by the
shareholders of the Company on March 19, 2009.

The Rights Plan has an initial term of three years. The
provisions of the Rights Plan are set out in an agreement dated as of February
2, 2009 between the Company and CIBC Mellon Trust Company, as Rights Agent, as
previously filed by the Company. At the Companys annual meeting of shareholders
held on February 10, 2012, the shareholders of the Company approved the renewal
of the Rights Plan for a further three years. The Rights Plan will expire at the
annual meeting of shareholders of the Company to be held in 2015, unless a
renewal of the Rights Plan is approved by shareholders of the Company at that
time.

The Rights Plan is designed to ensure the fair treatment of
shareholders in connection with any take-over bid for Common Shares of the
Company. The Rights Plan seeks to provide shareholders with adequate time to
properly assess a take-over bid without undue pressure. It also provides the
Board with more time to fully consider an unsolicited take-over bid and, if
applicable, to explore other alternatives to maximize shareholder value.

|(b) | was subject to an cease trade or order similar to a cease
      trade order, or an order that denied the relevant company access to any
      exemptions under Canadian securities legislation, for a period of more
      than 30 consecutive days, that was issued after the director or executive

      financial officer and which resulted from an event that occurred while
      that person was acting in the capacity as director, chief executive
      officer or chief financial officer.

Mr. Bovaird was a director of HMZ Metals Inc. (HMZ) at
the time a management cease trade order was issued on September 6, 2005
requiring the directors, officers and insiders of HMZ to cease all trading in,
or acquisition of, the securities of HMZ due to HMZs failure to file its
interim financial statements for the six month period ended June 30, 2005. The
management cease trade order issued on September 6, 2005 expired on October 20,
2005. The management cease trade order issued on April 3, 2006 expired and was
replaced with a permanent management cease trade order dated April 17, 2006,
which was allowed to expire on June 2, 2008. Mr. Bovaird was also an independent
director of Fort Chimo Minerals Inc. (Fort Chimo) at the time a
management cease trade order was issued on June 5, 2007 requiring the directors,
officers and insiders of Fort Chimo to cease all trading in, or acquisition of,
the securities of Fort Chimo due to Fort Chimos failure to file its interim
financial statements for the three month period ended March 31, 2007. The
management cease trade order was allowed to expire on July 9, 2007 after Fort
Chimo remedied the filing default.

Mr. Carroll is a director and President and Chief Executive
Officer of World Wide Minerals Ltd., a Canadian public company which is subject
to an issuer cease trade order issued by the Ontario Securities Commission on

trade order issued by the Ontario Securities Commission on June 3, 2004, as
varied, in respect of Argus, and June 1, 2004, as varied, in respect of
Hollinger. Both management cease trade orders were issued because of Argus and
Hollingers failure to file their respective financial statements and other
requisite reports and have not expired. Argus and Hollinger were not able to
file such financial statements and reports as a result of the non-filing of
financial statements by their subsidiary Hollinger International, Inc. (now
Sun-Times Media Group, Inc.).

In 2003 and 2004, the Pacific District Council of the
Investment Dealers Association (PDC-IDA) investigated Mr. Khans
previous employer, IPO Capital Corp. and the activities of a number of
registered representatives that took place in 1999. During the relevant period,
Mr. Khan was Chairman and CEO of IPO Capital Corp. In August 2004, Mr. Khan
entered into a settlement agreement with PDC-IDA accepting that he failed to
prohibit one of the representatives from selling debtor certificates to IPO
Capital Corp. clients, when he knew, or ought to have known, that the only
person doing due diligence was not qualified to conduct proper due diligence
with respect to the investment. Mr. Khan was fined
$8,000 and paid $2,000 in investigative costs for failing to observe high standards of conduct contrary to PDC-IDA By-Law 29.1.

LEGALPROCEEDINGS ANDREGULATORYACTIONS


Except as described below, the Company is not currently a party
to, nor was it a party to during the last financial year, and none of the
Companys property is or was the subject of, any material legal proceedings, and
the Company knows of no such legal proceedings that are contemplated. The
Company is not subject to any penalties or sanctions and has not entered into
any settlement agreements with a court or securities regulatory authority.
However, from time to time, the Company may become party to routine litigation
incidental to its business.

WHITEMESAMILL

One of the Companys subsidiaries, Energy Fuels Resources (USA)
Inc. (EFRI), entered into a unit price construction contract with KGL
Associates, Inc. (KGL) in 2009 relating to the construction of tailings
cell 4B at the Companys White Mesa Mill. EFRIs and KGLs performance of their
respective obligations under this contract was under dispute in an action
commenced in January 2011 in the Seventh Judicial District Court, San Juan
County, Utah. In the dispute: (a) EFRI sought approximately $3.25 million in
damages from KGL, including project completion costs as well as indemnity and
reimbursement from KGL for monies paid by EFRI to KGL subcontractors or
suppliers unpaid when KGL abandoned the project; (b) KGL sought payment of
approximately $1.65 million for alleged project labor and/or equipment
inefficiencies allegedly caused by EFRI or its engineer and to enforce its lien
against the Mill property; and (c) both parties sought pre-judgment interest,
attorney fees and costs. The parties agreed to resolve this matter in binding
arbitration. Under the Arrangement Agreement dated May 23, 2012 between the
Company and Denison Mines Corp., which was entered into in connection with the
acquisition by the Company of the Denison US Mining Division in June 2012,
Denison agreed to fully indemnify the Company in connection with this litigation
and will receive any proceeds from arbitration. On February 28, 2014 the
arbitrator found in favor of Denison and awarded damages, interest, attorneys
fees and costs to Denison in excess of $4.8 million. On March 21, 2014, KGL
filed a motion with the district court to vacate the award. Denisons counsel is
preparing Denisons response to that motion.

On January 11, 2013, the Ute Mountain Ute tribe filed a
Petition to Intervene and Request for Agency Action challenging the Corrective
Action Plan approved by the State of Utah Department of Environmental Quality
(UDEQ) relating to nitrate contamination located in the shallow aquifer
at the Companys White Mesa Mill site. This challenge is currently being
evaluated by UDEQ and the Company, and may involve the appointment by UDEQ of an
Administrative Law Judge to hear this matter under Utah administrative
procedures. If appointed, the Administrative Law Judge will set a schedule for
further proceedings which will involve a hearing to resolve the challenge. After
the hearing, the judge will issue a recommended decision to the final agency
decision maker, the Director of UDEQ. An appeal can be taken from the Director's
decision to Utah's appellate courts. The Company does not consider this action
to have any merit. If the petition is successful, the likely outcome would be a
requirement for the Company and UDEQ to modify or replace the existing
Corrective Action Plan. At this time, the Company does not believe that any such
modification or replacement would materially affect the Companys financial
position, results of operations or cash flows. However, the scope and costs of
remediation under a revised or replacement Corrective Action Plan have not yet
been determined and could be significant.

On November 26, 2012, the Company was served with a Plaintiffs
Original Petition and Jury Demand in the District Court of Harris County, Texas,
claiming an unspecified amount of damages from the disease and injuries
resulting from mesothelioma from exposure to asbestos, which the Plaintiff
claims was contributed to by being exposed to asbestos products and dust from
asbestos products while working at
the White Mesa Mill. The Plaintiff has also named a number of manufacturers of asbestos and asbestos-related products in the law suit.  The Company does not consider this claim to have any merit, and therefore does not believe it will materially
affect the Company’s financial position, results of operations or cash flows.  Plaintiff has produced a medical expert report, work history, and answers to discovery.  On January 28, 2013, the Company filed a Special Appearance to Challenge
Personal Jurisdiction, Motion to Transfer Venue, Motion to Dismiss for Forum Non Conveniens and Original Answer Subject Thereto.

The Company received a letter entitled “Notice of Intent to Sue Energy Fuels for Violations of the Clean Air Act at the White Mesa Uranium Mill” dated January 29, 2014. In the notice letter, the Grand Canyon Trust threatens to file a
Clean Air Act citizen suit in federal district court for alleged violations of the National Emissions Standards for Hazardous Pollutants (“NESHAPs”) Subpart W, which applies to uranium mills. The notice alleges that radon from
Cell 2 at the mill exceeds the 20 pCi/m2 standard; that the mill is in violation of the limitation to two operating tailings impoundments; and that two tailings impoundments exceed a 40 acre size limitation. No suit has been filed at this
time, and can only be filed after 60 days have elapsed from service of the notice letter. In the notice letter, the Grand Canyon Trust stated that it intends to ask the district court to impose injunctive relief, civil penalties of up to $37,500
per day per violation, its costs of litigation including attorneys’ fees, and other relief. The Company does not believe the claims threatened in the notice letter have merit, and intends to defend any lawsuit filed pursuant to the notice. The
Company believes the issues raised by this environmental group are either inaccurate or are being addressed through the proper regulatory channels. Both Energy Fuels and the regulatory authorities are well aware of these matters, and because they
are being addressed, no violations have been issued.

CANYONPROJECT

On March 7, 2013, the Center for Biological Diversity, the Grand Canyon Trust, the Sierra Club and the Havasupai Tribe (the “Plaintiffs”) filed a complaint in the U.S. District Court for the District of Arizona (the
“District Court”) against the Forest Supervisor for the Kaibab National Forest and the U.S. Forest Service (“USFS”, collectively, the “Defendants”) seeking an order declaring that the USFS failed to comply
with environmental, mining, public land, and historic preservation laws in relation to the Company’s Canyon Project, and setting aside and vacating any approvals and authorizations regarding exploration and mining operations at the Canyon
Project.  In addition, the Plaintiffs sought injunctive relief directing operations to cease at the mine and enjoining the USFS from authorizing or allowing any further exploration or mining-related activities at the Canyon Project until the USFS
fully complies with all applicable laws. In April 2013, the Plaintiffs filed a Motion for Preliminary Injunction to enjoin the Defendants from allowing construction and/or mining activities to occur at the Canyon Project and suspending all USFS
approvals. This motion was denied by the District Court on September 9, 2013. In October 2013 Plaintiffs appealed the District Court’s Order to the 9th Circuit Court of Appeals (the “Court of Appeals”), and filed
two Emergency Motions for an Injunction Pending Appeal. In November 2013, the Company decided to place shaft sinking operations on standby at the Canyon Project, due to market conditions, and to simplify and lessen the expense of the litigation at
the mine. At the same time, the Company entered into a stipulation agreement with Plaintiffs under which the Company agreed to keep shaft sinking operations on standby until the earlier of the date the District Court issues a final appealable order
on the merits of Plaintiffs’ claims, or December 31, 2014. In return, Plaintiffs agreed to stay their appeal of the District Court’s denial of their Motion for Preliminary Injunction in the Court of Appeals, and the emergency motions
related thereto. As a result of this stipulation agreement, the Court of Appeals stayed Plaintiffs’ appeal and emergency motions. Proceedings on the merits of the case are ongoing.  If the Plaintiffs are successful on the merits, the Company
may be required to maintain activities at the mine on standby for longer than otherwise planned, pending resolution of the matter.

Such a required prolonged stoppage of mine development and
mining activities could have a significant impact on the Company.

ROCAHONDA

On August 19, 2011, the Companys subsidiary, Roca Honda
Resources, LLC (Roca Honda), filed an application for a permit to
dewater certain aquifers underlying Roca Hondas proposed uranium mine site. The
Pueblo of Acoma protested the permit application, and the proceeding was
assigned to an Office of the State Engineer Hearing Officer. The matter was set
for hearing on the merits commencing on November 12, 2010. On December 10, 2010,
the Hearing Officer issued a Report and Recommendation which recommended
approval of the application. The State Engineer adopted the Report and
Recommendation of the Hearing Examiner on December 10, 2013. On January 13, 2014
Acoma Pueblo challenged the State Engineers granting of the permit by (1)
filing a notice of appeal and (2) separately filing a Complaint. The notice of
appeal and Complaint were both filed in the Eleventh Judicial District Court of
McKinley County. The Company does not believe the appeal and Complaint have
merit, and intends to defend against those actions. On March 14, 2014, the
Company filed a Motion to Dismiss the Complaint, on the basis that the appeal is
the exclusive remedy and that the Complaint is therefore not authorized under
law, is duplicative, wasteful and should be dismissed. If the appeal is
successful, the likely outcome would be remand of the permit back to the State
Engineer for reconsideration or possible withdrawal of the permit. At this time,
the Company does not believe that any such outcome would materially affect the
Companys financial position, results of operations or cash flows.

PIÑONRIDGEMILL

On April 25, 2013, the Colorado Department of Public Health and
Environment (CDPHE) re-issued the radioactive materials license (the
License) to the Company for the proposed Piñon Ridge Mill. On May 24,
2013, Sheep Mountain Alliance (SMA) and Rocky Mountain Wild
(RMW), two non-government organizations, filed a suit in Denver
District Court challenging the re-issuance of the License. On July 5, 2013, the
Company and CDPHE filed motions to dismiss a majority of the claims of SMA and
RMW. In September 2013, the court denied both motions to dismiss. In March,
2014, the Plaintiffs designated the record for the judicial appellate review in
Denver District Court. Now that the record has been designated, a briefing
schedule will be agreed to by the parties, and unless additional motions are
filed, briefing will commence fairly promptly, with the Plaintiffs filing the
opening briefs. If the appeal is successful, the likely outcome would be remand
of the License back to CDPHE for reconsideration consistent with the courts
ruling, with the possibility of further public input and/or procedural steps to
be taken, or possible withdrawal of the License.

CHARTER OF THE AUDIT COMMITTEE

The responsibilities and composition requirements of audit
committees are as set out in the Canadian Securities Administrators National
Instrument 52-110-Audit Committees ("NI 52-110"), the rules of the NYSE MKT
Company Guide (the Company Guide), the Sarbanes-Oxley Act of 2002 (SOX), and
the rules and regulations promulgated by the United States Securities and
Exchange Commission (SEC).

Audit Committee Mandate

The Audit Committee (the "Committee") is a committee
established and appointed by and among the Board of Directors of the Company
(the Board) to assist the Board in fulfilling its oversight responsibilities
of the Company. In so doing, the Committee provides an avenue of communication
among the external auditor, management, and the Board. The Committee's purpose
is to ensure the integrity of financial reporting and the audit process, and
that sound risk management and internal control systems are developed and
maintained. In pursuing these objectives the Audit Committee oversees relations
with the external auditor, reviews the effectiveness of the internal audit
function, and oversees the accounting and financial reporting processes of the
Company and audits of financial statements of the Company.

      auditors work plan and scope of the auditors review and all related
      fees. The external auditor shall report directly to the
  Committee.

Indicated Mineral Resource

An Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of
technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit.  The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from
locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.

Inferred Mineral Resource

An Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade
continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes
