affecting the Property and all successions thereof whether created privately or
through governmental action. In the event a court of competent jurisdiction
determines that the term of this Agreement violates the Rule Against
Perpetuities, then the term of this Agreement shall automatically be revised and
reformed to coincide with the maximum term permitted by the Rule Against
Perpetuities, and this Agreement shall not be terminated solely as a result of a
violation of the Rule Against Perpetuities.

4.            Production
Royalty. Grantor shall pay to Grantee a perpetual Royalty in the amount
of two percent (2%) on all ores produced from any or all of the Property, which
royalty shall be assignable by Grantor and shall be computed as set forth
herein.

Grantor shall pay to Grantee a royalty on all substances
produced and sold by Grantor from the Property, which royalty shall be computed
as follows:

For all uranium-bearing ores and solutions (i.e., mined
substances that are mined primarily for their uranium content) which are mined
and removed from the Property for sale or processing for the production of
“yellowcake” (U3O8 concentrate), whichever in Grantor’s discretion it shall
elect, the royalty reserved shall be as follows:

(1) Two percent (2%) of the value of the uranium in the form of
“yellowcake” recovered from ores mined and removed from the Property when
processing for such recovery is by Grantor prior to sale, or by a third party or
mill owned or controlled by Grantor. The value of the yellowcake for this
purpose shall be the average sale price, less transportation and other delivery
costs to the point of sale, received therefor by Grantor, or by the mill or
third party owned or controlled by it, for all yellowcake processed from ores
mined and removed from the Property and sold by Grantor, or sold by such owned
or controlled mill or third party, during the twelve (12) month period
immediately preceding the particular calendar month in which yellowcake is sold
and upon which royalty is to be computed.

(2) Two percent (2%) of the value of the uranium ores mined,
removed and sold from the Property by Grantor when such ores are sold in
unprocessed form by Grantor to a mill or third party which is not owned or
controlled by Grantor. The value of the ore for this purpose shall be the actual
proceeds received for such ores by the Grantor after deducting costs, if any,
for transporting and delivering such ores from the mine to the point of
sale.

(3) Two percent (2%) of the value of the yellowcake produced
from uranium-bearing mine water, leachates, pregnant liquors, pregnant slurries
(hereinafter referred to as “uranium-bearing solutions”) produced by in situ,
heap leaching or other solution mining process when processing for recovery is
by Grantor prior to sale, or by a third party or mill owned or controlled by
Grantor. The value for this purpose shall be the average sale price received for
the yellowcake so produced and sold by Grantor, or third party or mill owned or
controlled by Grantor, less costs of transportation and delivery of such
yellowcake to the point of sale, during the twelve (12) month period immediately
preceding the particular calendar month in which yellowcake produced from
uranium-bearing solutions from the Property is sold and upon which royalty is to
be computed.

(4) Two percent (2%) of the value of uranium-bearing solutions
produced from the Property when such solutions are sold in unprocessed form by
Grantor to a mill or third party which is not owned or controlled by Grantor.
The value of the uranium-bearing solutions for this purpose shall be the actual
proceeds received for such uranium-bearing solutions by the Grantor after
deducting costs, if any, of transporting and delivering such uranium-bearing
solutions from the project site to said mill or third party (point of sale).

               In
the event ores or uranium-bearing solutions mined and removed from the Property
are subject to computation of royalties pursuant to (1) or (3) above, and such
ores or solutions are processed for recovery of yellowcake in a mill which
processes other ores or solutions as well as ores or solutions from the
Property, such ores and solutions shall be separately weighed and sampled before
being commingled with said other ores or solutions. The amount of yellowcake
recovered from such ores or solutions mined from the Property shall be
determined on the basis 

of assays of such samples and the average recovery percentage
of that mill during the month in which said ores or solutions are processed.

In the event ores mined from Property are processed for
recovery of yellowcake pursuant to (1) above, and if Grantor or the mill or
third party owned or controlled by it, recovers and markets valuable
constituents other than yellowcake from said uranium-bearing ores as by-products
during the processing of such ores, then Grantee shall receive as royalty two
percent (2%) of the net proceeds received by Grantor from the sale of such
by-products. For purposes of computing this royalty, net proceeds shall be
defined as the actual proceeds received by Grantor for such byproducts less
costs of transporting said by-products to the point of sale.

5.     
      Production Royalty For Precious and
Other Minerals. Grantor shall pay to Grantee a perpetual Royalty in the
amount of two percent (2%) of Net Smelter Returns from the sale or other
disposition of all locatable minerals (other than uranium) produced from the
Property determined in accordance with the provisions set forth in the Rocky
Mountain Mineral Law Foundation’s Model Form Exploration, Development and Mine
Operating Agreement Form 5A. 

6.           General
Provisions.

               6.1    
 The Miscellaneous Provisions set forth in Article 12 of the Main
Agreement shall apply to this Schedule A as applicable.

               6.2     
In this Schedule A in all matters of interpretation, whenever necessary to
give effect to any provision of this instrument, the masculine shall include the
feminine and neuter and vice versa, the singular shall include the plural, and
the plural shall include the singular.Filed by Automated Filing Services Inc. (604) 609-0244 - Uranerz Energy Corporation - Exhibit 10.5

accordance with the formula:

A = B x 100%, where:

such immediate actions and make such immediate Expenditures as the Operator
deems necessary to keep the Property in good standing or for the protection of
individuals and/or property and/or the environment. The Operator shall
promptly report such emergency actions and Expenditures to the non-Operator by
delivering an invoice to the non-Operator. The non-Operator shall pay its
share of the Expenditures to the Operator in accordance with Section 5.4 of this
Schedule “B”.

4.5       Contingency Fund.
The Operator may establish and administer a contingency fund to be applied
by the Operator to satisfy any legal obligations of the Parties respecting a
mine maintenance plan or mine closure plan, including obligations for severance
pay, pensions, rehabilitation and reclamation work. Each Party shall
contribute its proportionate share of such fund based on such Party’s Joint
Venture Interest at the time of the establishment of the fund (or at the time of
the contribution, in respect of subsequent contributions). The Operator shall
invest any unused portion of such fund and all income thereon shall accrue in
such fund. If the Operator determines that such fund, or any portion thereof, is
no longer necessary, the Operator shall make payments to the Parties in
proportion to their contribution to such contingency fund on the date of such
payments.

SECTION 5. - PROGRAMS.

5.1       Contents of Program.
The Operator shall prepare a Program and submit such Program budget to the
Management Committee for approval at least sixty (60) days before the beginning
of each calendar year. The Management Committee must approve each Program prior
to implementation. Each Program shall cover a period of up to 12 months or such
other period as the Parties may agree. Each Program must contain:

	(a) 	
      a reasonably detailed outline of all work which the
      Operator contemplates carrying out on the Property under such Program
      detailing the areas on the Property to be subject to such work and the
      time frame for each of the major elements of such work; 

	 	
       

	(b) 	
      a reasonably itemised budget, broken down by month, of
      the projected Expenditures under the Program; and 

	 	
       

	(c) 	
      the estimated amount and date of each payment that the
      non-Operator would have to make to the Operator. 

5.2       Election by
Representatives. If the Operator proposes a Program which is approved by the
Management Committee:

	(a) 	
      for less than One Million Dollars ($1,000,000), the
      Representatives shall then have 60 days to elect whether or not to
      participate in the Program; or 

- 7 -

	(b) 	
      for more than One Million Dollars ($1,000,000), the
      Representatives shall then have 60 days to elect to participate in the
      Program, and a further 90 days to raise their share of the funding
      required. 

5.3       Approved Programs.
The Operator shall carry out each Program approved by the Management
Committee provided the Parties who have elected to contribute to such Program
provide the Operator with their proportionate share of the funding in respect of
the Program.

5.4       Payments to
Operator. If a Representative elects to participate in a Program on behalf
of a Party, the Operator will submit an invoice to such Representative on or
between the first and 20th day of the month immediately preceding a month in
which Expenditures are to be made under a Program. The invoice must set
out the estimated Expenditures under the Program for the immediately following
month, multiplied by the Joint Venture Interest of such Party. Within 30
days of receipt of such invoice, such Party shall pay the Operator the invoice
amount. The Operator may also submit other invoices relating to
reconciliations, bills, accounts or other requests for payment in respect of any
Expenditures made by the Operator under a Program or otherwise in accordance
with this Agreement. Such invoice must set out the total amount involved,
multiplied by the participating Party’s Joint Venture Interest. Within 30 days
of receipt of such invoice, such Party shall pay the Operator the invoice
amount. If such Party fails to make any payment to the Operator under
this Section 5.4 of this Schedule “B” within any applicable 30 day payment
period, after previously having elected to do so, such Party shall make such
payment together with an interest payment, calculated at the rate equal to the
annual rate of interest announced from time to time by the Canadian Imperial
Bank of Commerce as its reference rate then in effect for determining interest
rates on Canadian dollar commercial loans in Canada (commonly known as its prime
rate), plus 10%, for the period commencing on the expiry of such 30 day payment
period and terminating on the date that full payment is made. If such
Party fails to make full payment, including in respect of interest, to the
Operator within 60 days of the expiry of the applicable 30 day payment period,
Section 5.6 of this Schedule “B” applies.

5.5       Failure to
Participate. If a Party does not elect to participate in a Program, its
Joint Venture Interest shall be diluted in accordance with Section 2.2 of this
Schedule “B”.

5.6       Failure to Make
Payment by non-Operator. If a Party which has elected to participate in a
Program fails to make a required payment within the 60 day period referred to in
Section 5.4 of this Schedule “B”, such Party’s Joint Venture Interest shall be
diluted at a rate of two times normal dilution.

5.7       Failure to Spend at
Least 80% of Budget. If a Party does not elect to participate in a Program
and the Operator does not make Expenditures under the Program at least equal to
80% of budgeted Expenditures, the non-participating Party shall not have its
Joint Venture Interest reduced in accordance with Section 2.2 of this Schedule
“B” if the non-participating Party promptly pays the Operator, following the
completion of such Program, an amount equal to the total Expenditures made under
such Program, multiplied 

- 8 -

by the non-participating Party’s Joint Venture Interest,
determined at the commencement of such Program.

5.8       Expenditures More
Than 10% Above Budget. Expenditures made by the Operator exceeding the
Expenditures contemplated by the Program by less than 10% will be funded by the
Parties in proportion to their Joint Venture Interests. Expenditures made
by the Operator exceeding the Expenditures contemplated by the Program by more
than 10% will be funded solely by the Operator, unless otherwise agreed by the
Parties in writing. Unless otherwise agreed by the Parties in writing,
any such payments exceeding the Expenditures contemplated by the Program by more
than 10% which are made by either the Operator or the non-Operator will not form
part of the calculations used to determine the Joint Venture Interests of the
Parties in accordance with Section 2.2 of this Schedule “B”.

5.9       Return of Surplus
Monies. If, after completion of any Program, the Operator is in possession
of any moneys contributed by the Parties and which are not required for the
discharge of obligations relating to such Program, the Operator shall repay such
moneys to the contributing Parties.

5.10      Failure to Submit
Program to Management Committee. If the Operator does not submit a Program
involving Expenditures of at least $50,000 to the Management Committee for
approval within a period of at least 6 months from the date of completion of the
last Program (being when the report is complete and delivered to the
non-Operator), then the non-Operator may propose a Program to the Management
Committee for an amount not less than $50,000. If the non-Operator makes
such a proposal and the Program is approved by the Management Committee, the
Operator shall carry out such Program and fund its proportionate share.
If the Management Committee does not approve such Program, the non-Operator
may, notwithstanding Section 4.2 of this Schedule “B”, become the Operator and
carry out the Program. Following the completion of such Program Section
4.2 of this Schedule “B” shall apply once again.

SECTION 6. - DEALINGS WITH AFFILIATES.

Any Joint Venture Assets that the Operator may purchase, lease
or rent from an Affiliate shall be purchased, leased or rented at fair market
value. The cost of all work which the Operator may contract to an Affiliate
shall be equal to the fair market value of such work. Any Joint Venture Assets
that the Operator may sell or otherwise dispose of to an Affiliate shall be sold
or otherwise disposed of at fair market value. The Operator shall pay the net
proceeds received in respect of such Joint Venture Assets, if any, to the
Parties in proportion to their respective Joint Venture Interests. The Operator
shall give the non-Operator written notice of any significant transaction with
an Affiliate and the non-Operator may, at any time within 12 months after it has
received such notice, dispute whether such transaction was at fair market
value.

SECTION 7. - USE OF SURPLUS JOINT VENTURE ASSETS.

Subject to Section 5.9 of this Schedule “B”, the Operator may
use any Joint Venture Assets which are no longer required for the Joint Venture
for such other purposes and on such terms as the Operator may from time to time
determine. The Operator shall pay the net proceeds received in respect of
such Joint Venture Assets, if any, to the Parties in proportion to their
respective Joint Venture Interests. If such surplus Joint Venture Assets
are used by the Operator, outside the scope of the Joint Venture, or are used by
an Affiliate of the Operator, outside the scope of the Joint Venture, then the
net proceeds in respect of such use shall be deemed to be an amount equal to
what could be obtained from an arms-length third party.

SECTION 8. - DISPOSITION OF SURPLUS JOINT VENTURE
ASSETS.

Subject to Section 3.8 of this Schedule “B”, the Operator may
from time to time sell or otherwise dispose of such part of the Joint Venture
Assets as are no longer required for Joint Venture operations. The
Operator shall pay the net proceeds received in respect of such Joint Venture
Assets, if any, to the Parties in proportion to their respective Joint Venture
Interests.

SECTION 9. - INSURANCE PROCEEDS.

The Operator shall apply, to the extent determined by the
Operator, any insurance proceeds received by the Operator in respect of any loss
or damage to Joint Venture Assets towards the repair or replacement of the lost
or damaged Joint Venture Assets. The Operator shall pay the remaining
proceeds received in respect of such Joint Venture Assets, if any, to the
Parties in proportion to their respective Joint Venture Interests.

SECTION 10. - SETTLEMENT PAYMENTS.

Subject to Section 3.8(c) of this Schedule “B”, all losses,
costs, expenses, claims or damages, including legal fees and disbursements, net
of any insurance proceeds, incurred and paid by the Operator in settlement of
any loss, cost, expense, claim, damage, judgement or similar matter (including a
payment made, or an action taken, by the Operator as a result of an action of a
governmental agency) shall constitute an Expenditure made by the Operator under
the applicable Program. In addition, the non-Operator, in proportion to
its Joint Venture Interest calculated on the date that the initial liability was
incurred which gives rise to this indemnification obligation, shall indemnify
and hold harmless the Operator for any loss, cost, expense, claim or damage,
including legal fees and disbursements, suffered or incurred by the Operator in
respect of a third party claim (including an action of a governmental agency
which results in a payment made, or an action taken, by the Operator), except to
the extent that such claim arose from the gross negligence or wilful misconduct
of the Operator.

SECTION 11. - LIABILITY OF OPERATOR.

The Operator shall not be liable to the non-Operator for any
loss, cost, expense, claim or damage, including legal fees and disbursements,
(including a payment made, or an action 

- 10 -

taken, by the Operator as a result of an action of a
governmental agency) except to the extent that such loss, cost, expense, claim
or damage is attributable to the gross negligence or wilful misconduct of the
Operator. In no event (including fundamental breach) shall the Operator
be liable to the non-Operator for any indirect, special or consequential damages
(including for loss of goodwill, loss of actual or anticipated profits or other
economic loss), even if the Operator has been advised of the potential for such
damages.

SECTION 12. - GST.

At the request of the Operator, the Parties shall promptly
execute all documents and take all other actions required to make (and file, if
necessary) the election referred to in section 273 of the Excise Tax Act
(Canada), with a view to authorizing the Operator to pay, from time to time,
on behalf of the other Party, all taxes which relate to the Joint Venture and
which may become due and payable under Part IX of the Excise Tax Act
(Canada). This Section 12 of this Schedule “B” shall apply, with such
changes as are required in the circumstances, in respect of any similar
applicable provincial legislation.

SECTION 13. - NO PARTITION.

Subject to Section 3.8 of this Schedule “B”, no Party may seek
or obtain partition of any of the Joint Venture Assets, including the Property,
or any interest therein whether by way of physical partition, sale or
otherwise. No statute, regulation or law providing for partition, or
partition and sale, shall apply to any of the Joint Venture Assets.

SECTION 14. - NO RESTRICTION ON OTHER ACTIVITIES.

Each Party has the unrestricted right to engage in, and receive
the full benefit of, any activity outside the scope of the Joint Venture,
without consulting with, or accounting to, the other party, or permitting the
other party to participate in such activity.

SECTION 15. - TERMINATION.

If the Parties agree to terminate the Joint Venture, the
Operator may take any actions necessary or desirable to wind up the Joint
Venture. All costs, charges and expenses of winding up the Joint Venture
(including in respect of any reclamation) shall be for the account of the Joint
Venture and the Parties shall divide the net Joint Venture Assets in proportion
to their Joint Venture Interests, although any loans advanced to the Joint
Venture by a Party shall be satisfied before any other distribution of assets is
made to the Parties. Once the said costs, charges and expenses have been
paid in full, the Operator may sell the Joint Venture Assets (with the prior
approval of the non-Operator, where Joint Venture Assets are sold for a total
amount of in excess of $100,000) or distribute the Joint Venture Assets to the
Parties in kind.

SECTION 16. - WITHDRAWAL FROM JOINT VENTURE.

16.1      Right of Withdrawal and

SECTION 18. - RIGHTS TO MINERAL PRODUCTS

18.1     Each Party shall own and have the
right, privilege and power to take in kind and separately dispose of a portion
of all Mineral Products produced from the Property, in accordance with its Joint
Venture Interest. The Operator shall designate and notify the Parties of
the points of delivery situated on the Property for the Parties respective Joint
Venture shares of such Mineral Product and all costs in respect of such Mineral
Products shall be for the account of the Joint Venture, until such Mineral
Products are delivered to such points. After such Mineral Products are
delivered to such points each Party shall pay its own costs in respect of such
Mineral Products. The Operator shall use its best efforts to ensure that
each Party receives product of like quality.

18.2     The Operator shall have no
obligation in respect of the Parties’ Mineral Products after delivery of such
Mineral Products to the point of delivery provided, however, that if a Party is
prepared to sell its Mineral Products at the same time and on the same terms and
conditions as the Operator is selling its own Mineral Products and so advises
the Operator the Operator may, but is not obligated to, act as an agent for the
Non-Operator in relation to the sale of the Non-Operator’s Mineral Products on
the terms and conditions that are equivalent to the terms and conditions
obtained for its own Mineral Products. If the Operator elects to act as
agent for the Non-Operator, it may discontinue such agency at any time upon
giving the Non-Operator 30 days advance notice. If the Operator, while
acting as the Non-Operator’s agent, is of the opinion that 100% of its own
Mineral Products and 100% of the Non-Operator’s Mineral Products available for
sale cannot be sold at the same time for revenue deemed acceptable by the
Operator, the Operator shall arrange for sales of a lesser amount of each
Party’s Mineral Products on a pro rata basis. In the event that the
Operator acts as an agent for the Non-Operator, the Operator shall be entitled
to sale commissions equal to prevailing rates charged by other agents for
effecting similar sales. In the event of a non-arm’s length sale of
Mineral Products, such sale shall be at commercially competitive rates.

      equal to the credit balance in the Royalty Account shall be distributed
      90% to the Owner and 10% to the Payee. 

	 	
       
	
       

	3.
