Commitment for that year, then up to 20% of the excess expenditures, as measured against the Project Work Commitment for that year,
shall be credited toward the minimum Project Work Commitment expenditures for the following years. In any given year, if Rocky
Mountain incurs expenditures below the required Project Work Commitment for that year, then up to 20% of the expenditure shortfall,

payments to Barrick Bullfrog equal to the remaining expenditure shortfall for the year. Further, if Rocky Mountain incurs expenditures
below the required Project Work Commitment for a given year but elects not to carry forward any shortfall to the subsequent year,

to the Properties, including reclamation, or cause the same to be performed, and shall safeguard and maintain the Properties in
compliance with all applicable laws, statutes, ordinances and regulations and in a manner consistent with generally accepted standards
and practices of the mining industry. Before exercising its Working Right or commencing Mining Operations in a manner that will
cause ground disturbance on the Properties, Rocky Mountain shall ensure that (i) a cultural resources survey and inventory on the
affected lands has been performed within the last five years, and (ii) Rocky Mountain has submitted to Barrick Bullfrog for approval
a social and stakeholder engagement plan. If no such cultural survey or inventory has been performed within the last five years,
Rocky Mountain shall cause such a cultural resources survey and inventory to be undertaken for the Properties, or the portions
affected by ground disturbance, before any ground disturbance shall occur. The social and stakeholder engagement plan shall include
provisions for engaging local and regional stakeholders, including governmental and non-governmental entities, regarding the intended
work to be done on the Properties. The social and stakeholder engagement plan shall also address the procedures by which Rocky
Mountain will process, evaluate, and respond to information and other requests from stakeholders. Rocky Mountain’s social

it will not exercise its Working Right or conduct Mining Operations without first obtaining all necessary permits, bonds, and approvals.
Rocky Mountain further agrees to consult with Barrick Bullfrog, and submit any permit applications or other applications for governmental
approvals to Barrick




    	 



    	 



    

Bullfrog for review and approval, prior
to Rocky Mountain submitting such applications to the appropriate permitting authority or otherwise binding Rocky Mountain to a

Bullfrog hereunder or thereunder. 



		(b)	Subject to paragraph (d) below, Rocky Mountain shall not sell, assign, convey, transfer or otherwise

to or otherwise attach to, impair or encumber the Interest to be acquired by Barrick Bullfrog on exercise of the Back-In Right
in any way (or any product extracted therefrom); provided that Rocky Mountain shall be entitled to grant security to an arm’s
length lender in the normal and ordinary course of business, subject to paragraph (a) above.



		(d)	Rocky Mountain may Transfer the Back-In Properties to an Affiliate, provided (i) such Affiliate
agrees in writing with Barrick Bullfrog to comply with the obligations of a Transfer set forth in Section 2(b) of this Back-in
Right Agreement





    	 



    	 



    

and (ii) Rocky Mountain agrees to

actually received by Rocky Mountain;



		(f)	if Rocky Mountain fails to discharge the Encumbrances on the Back-In Properties as required by
this Back-In Right Agreement, Barrick Bullfrog may, but is not obligated to, discharge any such Encumbrance (and Rocky Mountain

the Consideration payable by Barrick Bullfrog to Rocky Mountain;

either directly or through an Affiliate, as the sole operator of the Back-In Properties; and



		(j)	Barrick Bullfrog and Rocky Mountain shall execute and deliver to each other such documents and
undertakings and take such other steps as counsel for each Party may reasonably require to give effect to such transfer of the

shall make its Books and Records available for such audit by an auditor acceptable to Barrick Bullfrog and Rocky Mountain acting

the exercise of the Back-In Right shall be completed (the moment of completion shall be referred to as “Closing”)
on that date (the “Closing Date”) which shall be the sixtieth (60th) day following the day of the
Back-In Notice was delivered to Rocky Mountain (or such longer period as may be necessary to obtain any consents of Governmental
Entities required to effect the transfer of the Interest). All documents and monies shall be delivered at the place of Closing
(which place shall be determined by Barrick Bullfrog, acting reasonably).


		5.	Maximum Duration of Agreement



Barrick Bullfrog’s Back-In
Right, unless otherwise terminated by other provisions herein contained, shall exist in perpetuity. If any right, power or interest
of a party under this Back-In Right Agreement would violate the rule against perpetuities or equivalent rule under applicable law,
then such right, power or interest shall terminate on the earlier of

years after the death of the last survivor of all the lineal descendants of Her Majesty, Queen Elizabeth II of England, living

Basic Terms of Joint Venture Agreement


It is agreed that the Joint Venture Agreement
required to be entered into pursuant to Section 3(f) of the Back-In Right Agreement shall contain, however not exclusively,
provisions on and with regard to matters set out below:


		1.	Barrick Bullfrog (or an Affiliate of Barrick Bullfrog) will be the Operator of the Joint Venture
and, as Operator, shall solely be responsible for and operate all work programs of the Joint Venture.



		2.	The activities of the Joint Venture will be directed by a Management Committee made up of representatives
of each Party voting in proportion to the respective interest of each of the Parties in the joint venture interest (the “JV
Interest”). Decisions of the Management Committee, unless otherwise provided, shall be by majority vote.



		3.	Prior to November 30th of each year (or such other time as determined by the Management
Committee), the Operator shall submit a work program and budget for the next ensuing calendar year to the Management Committee.
The Management Committee shall meet and shall decide to accept such program or modification of same within a month after the budget
is submitted by the Operator. If a Party to the Joint Venture fails to participate in the approved work program, it will be diluted
according to calculation in Section 8 of this Schedule.



		4.	All costs by the Joint Venture for the exploration and development of the Back-In Properties and
the subsequent operation of a mining venture shall be funded by each Party in proportion to its JV interest.



		5.	The Operator shall be entitled to charge to the Joint Venture a management fee equal to five (5%)
percent of all direct costs for the exploration stage, four (4%) percent of all direct costs for the development stage, and three
(3%) percent of all direct costs during the mining operation stage.



		6.	The Joint Venture Agreement shall provide for and include provisions on Barrick Bullfrog’s
right of first refusal to Rocky Mountain’s JV Interest if Rocky Mountain decides to dispose of its JV Interest.



		7.	The Joint Venture Agreement shall contain provisions on the following:



		(a)	If the JV Interest of Barrick Bullfrog or Rocky Mountain is reduced to less than ten (10%) percent,
the JV Interest shall be converted to a two (2%) percent Interest of the Net Proceeds of Commercial Production (“NPI”).
Net proceeds of Commercial Production shall mean proceeds received from material mined, milled and delivered to a smelter or refinery,
whether in the form of concentrates, bullion gold bars or in any other form suitable for treatment, less all exploration and development
expenditures and all capital and operating costs attributable to the mining, processing, handling and delivery of the material
so involved. The aggregate amount payable under the NPI royalty shall not exceed one hundred





    	 



    	 



    

(100%) percent of the expenditures
made by the diluting party from the date of the Joint Venture Agreement until the date the JV Interest was converted to a NPI.


		(b)	If the JV Interest of Barrick Bullfrog or Rocky Mountain is reduced to less than ten (10%) percent
due to voluntary withdrawal or for reasons other than default on payment obligations under a work program and budget, the JV Interest
shall be converted to a two (2%) percent interest of the Net Smelter Returns. Net Smelter Returns shall be the Receipts less the
Allowable Deductions pertaining to such Receipts, in each case for the applicable calendar quarter. Receipts shall mean the revenues
for products or Minerals (as defined in the Option Agreement) sold from the Properties, and if products or Minerals mined and removed
from the Properties are distributed to an Affiliate, then in such event the Receipts attributed to such products or Minerals shall
be the fair market value price that would otherwise be received from a third party in an arm’s length transaction. “Allowable
Deductions” means: (i) all tolling charges, representation expenses, metal losses, umpire charges, and penalties that are
either paid or incurred by the remaining Party or its Affiliates for or in connection with mineral treatment, or refining processes
or procedures after the products or Minerals leave the mine site; (ii) all costs and expenses actually incurred with, or in connection
with, the transporting, insuring, stockpiling, warehousing, shipping, and moving any of the products or Minerals produced from
the Properties and the delivery of such products or Minerals to a customer, refinery or other place of mineral treatment, including
without limitation, all transportation costs, insurance costs and expenses, shipping and delivery costs, agency and brokerage fees
and commissions, and storage charges; (iii) sales, use, gross receipts, customs duties, severance, government royalties, ad valorem,
VAT and other taxes and governmental charges, if any, payable with respect to the existence, severance, production, removal, sale,
processing, transportation, or disposition of products or Minerals, but excluding taxes based on the net income of the remaining
Party or its Affiliates; (iv) insurance, consignment, and any discounts or rebates given to customers for off specification or
damaged product. The aggregate amount payable under the Net Smelter Returns royalty shall not exceed one hundred (100%) percent
of the expenditures made by the diluting party from the date of the Joint Venture Agreement until the date the JV Interest was
converted to a Net Smelter Returns interest.



		8.	The Joint Venture Agreement shall contain provisions on the following: if a party (the Diluting
Party) to the Joint Venture Agreement declines to participate in an approved program/budget, the JV Interest of such party shall
be recalculated from time to time according to the following formula:



	 	R =	
        REA(P) x 100%

        REA(AP)

         
	 
	 	
        Where:

         





    	 



    	 



    

 


	 	R =	
        The Recalculated Participating Interest of the Diluting Party, expressed
        as a percentage.

         

	 	REA(P) =	
        The Diluting Party’s Equity Account balance immediately prior
        to the diluting date, as adjusted for anticipated debits and credits based on the adopted work program and budget and the Diluting
        Party’s election as to contributions.

         

	 	REA(AP) =	The Equity Account for all Parties immediately prior to the diluting date, as adjusted for anticipated debits and credits based on the adopted work program and budget and all Parties’ elections as to contributions.


The JV Interest of the other
party to the Joint Venture Agreement who is not a diluting Party (such party a “Non-Defaulting Party”) shall be increased
by the amount of the reduction in the JV Interest of the Diluting Party, and the manager shall adjust the relevant work program
and budget to reflect the funds available.


Where a party to the
Joint Venture Agreement defaults in making a payment that is due and owing to the Operator (such party a “defaulting party”)
the other party to the Joint Venture Agreement who is not a defaulting party (such party a “non-defaulting party”)
may elect to have the JV Interest of the defaulting party be diluted at twice the rate of dilution set forth above or purchase
the entirety of the defaulting party’s JV interest at a 10% discount to the fair market value of such JV Interest.


		9.	The Joint Venture Agreement shall also contain and include basic provisions on and with regard
to:



		(a)	Confidentiality of Information;



		(b)	Limitations on Encumbrances on the Property and JV Interests



		(c)	Management Committee Duties and Procedures;



		(d)	Responsibilities (including the reporting obligations of the Operator to the Management Committee)
and Indemnification of the Operator;

		(f)	The assumption of Liabilities with respect to the Back-In Properties by each of Rocky Mountain
and Barrick Bullfrog in proportion to their JV Interest; and



		(g)	Force Majeure.

liquidation or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by
other equitable principles of general application.


(c)

and the consummation by them of the transactions contemplated thereby do not and will not (i) conflict with or violate any provision
of the Company’s or any Subsidiary’s certificate or articles of incorporation, bylaws or other organizational or charter
documents, or (ii) conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a
default) under, result in the creation of any




    	 



    	 



    

Lien upon any of the properties or assets
of the Company or any Subsidiary, or give to others any rights of termination, amendment, acceleration or cancellation (with or
without notice, lapse of time or both) of, any agreement, credit facility, debt or other instrument (evidencing a Company or Subsidiary
debt or otherwise) or other understanding to which the Company or any Subsidiary is a party or by which any property or asset of
the Company or any Subsidiary is bound or affected, or (iii) result in a violation of any law, rule, regulation, order, judgment,
injunction, decree or other restriction of any court or governmental authority to which the Company or a Subsidiary is subject
(including federal and state securities laws and regulations), or by which any property or asset of the Company or a Subsidiary
is bound or affected; except in the case of each of clauses (ii) and (iii), such as could not, individually or in the aggregate,
have or reasonably be expected to result in a Material Adverse Effect.


(d)              
Filings, Consents and Approvals. Neither the Company or Rocky Mountain currently is required to obtain any consent,
waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state,
local or other governmental authority or other Person in connection with the execution, delivery and performance by the Company
of the Transaction Documents, other than (i) the filing of a Notice of Sale of Securities on Form D with the Commission under Regulation
D of the Securities Act and under applicable state securities statutes pertaining to the purchase and sale contemplated by this
Agreement, and (ii) those that have been made or obtained prior to the Closing Date.


(e)               
Issuance of the Shares. The Shares have been duly authorized and, when issued and paid for in accordance with the
Transaction Documents, will be duly and validly issued, fully paid and non-assessable, free and clear of all Liens. The Company
has reserved from its duly authorized capital stock the shares of Common Stock issuable pursuant to this Agreement in order to
issue the Shares. The Securities are not subject to any preemptive or similar rights to subscribe for or purchase securities.


(f)               
Capitalization. The number of shares and type of all authorized, issued and outstanding capital stock of the Company,
and all shares of Common Stock reserved for issuance under the Company’s various option and incentive plans, is as set forth
in the SEC Disclosure Documents. No securities of the Company are entitled to preemptive or similar rights, and no Person has any
right of first refusal, preemptive right, right of participation, or any similar right to participate in the transactions contemplated
by the Transaction Documents. Except as disclosed in the SEC Disclosure Documents, there are no outstanding options, warrants,
scrip rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities, rights or obligations
convertible into or exchangeable for, or giving any Person any right to subscribe for or acquire, any shares of the Company’s
capital stock, or contracts, commitments, understandings or arrangements by which the Company or any Subsidiary is or may become
bound to issue additional shares of its capital stock, or securities or rights convertible or exchangeable into shares of Common
Stock. The issue and sale of the Shares will not, immediately or with the passage of time, obligate the Company to issue shares
of Common Stock or other securities to any Person and will not result in a right of any holder of Company securities to adjust
the exercise, conversion, exchange or reset price under such securities. All of the outstanding shares of capital stock of the
Company are validly issued, fully paid and non-assessable, have been issued in compliance with all federal and state securities
laws, and none of such outstanding shares was issued in violation of any preemptive rights or similar rights to

stock of the Company. No further approval or authorization of any stockholder, the Board of Directors of the Company or others
is required for the issuance and sale of the Shares. There are no stockholders agreements, voting agreements, or other similar
agreements with respect to the Company’s capital stock to which the Company is a party or, to the Knowledge of the Company,
between or among any of the Company’s stockholders.

regulations of the Commission promulgated thereunder, and none of the SEC Disclosure Documents, when filed, contained any untrue

3.2             
Representations and Warranties of Barrick and Barrick Bullfrog. Barrick and Barrick Bullfrog, jointly and severally,
hereby represent and warrant to the Company and Rocky Mountain as follows:


(a)               
Organization; Authority. Each of Barrick and Barrick Bullfrog is an entity duly organized, validly existing and in
good standing under the laws of the jurisdiction of its organization with the requisite corporate or partnership power and authority
to enter into and to consummate the transactions contemplated by the applicable Transaction Documents and otherwise to carry out
its obligations thereunder. The execution, delivery and performance by Barrick and Barrick Bullfrog of the transactions contemplated
by the Transaction Documents has been duly authorized by all necessary corporate. Each of the Transaction Documents has been duly
executed by it, and when delivered by Barrick and Barrick Bullfrog, as applicable, in accordance with terms hereof, will constitute
its or their valid and legally binding obligation, enforceable against it in accordance with its terms, except as such enforceability
may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting
generally the enforcement of, creditors’ rights and remedies or by other equitable principles of general application.


(b)              
Investment Intent. Barrick is acquiring the Shares as principal for its own account for investment purposes only
and not with a view to or for distributing or reselling such Shares or any part thereof, without prejudice, however, to Barrick’s
right at all times to sell or otherwise dispose of all or any part of such Shares in compliance with applicable federal and state
securities laws. Subject to the immediately preceding sentence, nothing contained herein shall be deemed a representation or warranty
by Barrick to hold the Shares for any period of time. Barrick is acquiring the Shares hereunder in the ordinary course of its business.
Barrick does not have any agreement or understanding, directly or indirectly, with any Person to distribute any of the Shares.




    	 



    	 



    

(c)               
Investor Status. At the time Barrick was offered the Shares, it was, and at the Closing Date it will be, an “accredited
investor” as defined in Rule 501(a) under the Securities Act. Barrick is not a registered broker-dealer under Section 15
of the Exchange Act.


(d)              
General Solicitation. Barrick is not purchasing the Shares as a result of any advertisement, article, notice or other
communication regarding the Shares published in any newspaper, magazine or similar media or broadcast over television or radio
or presented at any seminar or any other general solicitation or general advertisement.


(e)               
Access to Information. Barrick acknowledges that it has reviewed the SEC Disclosure Documents and has been afforded
(i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company
concerning the terms and conditions of the offering of the Shares and the merits and risks of investing in the Shares; (ii) access
to information about the Company and Rocky Mountain and their respective financial condition, results of operations, business,
properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such
additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make
an informed investment decision with respect to the investment. Neither such inquiries nor any other investigation conducted by
or on behalf of Barrick or its representatives or counsel shall modify, amend or affect Barrick’s right to rely on the truth,
accuracy and completeness of the SEC Disclosure Documents and the Company’s representations and warranties contained in the
Transaction Documents.

IV.

OTHER AGREEMENTS OF THE PARTIES


4.1             
Restrictions on Transfer.


(a)Shares may
only be disposed of in compliance with state and federal securities laws. In connection with any transfer of the Shares other than
pursuant to an effective registration statement, to the Company, to an Affiliate of Barrick or in connection with a pledge as contemplated
in Section 4.1(b), the Company may require Barrick to provide to the Company an opinion of counsel selected by Barrick, the form
and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require
registration of such transferred Shares under the Securities Act.


(b)Certificates
evidencing the Shares will contain the following legend, until such time as they are not required under Section 4.1(c):


THESE SECURITIES HAVE NOT BEEN
REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION
FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE
OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION
FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT




    	 



    	 



    

AND IN ACCORDANCE WITH APPLICABLE
STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL
BE REASONABLY ACCEPTABLE TO THE COMPANY. THESE SECURITIES MAY BE PLEDGED AS SECURITY ON BORROWINGS BY THE HOLDER.


The Company acknowledges
and agrees that Barrick may from time to time pledge, and/or grant a security interest in some or all of the Shares pursuant to
a term loan, loan arrangement, credit facility, or other borrowing arrangement and, if required under the terms of such loan or
arrangement, Barrick may transfer pledged or secured Shares to the pledgees or secured parties. Such a pledge or transfer would
not be subject to approval or consent of the Company and no legal opinion of legal counsel to the pledgee, secured party or pledgor
shall be required in connection with the pledge, but such legal opinion may be required in connection with a subsequent transfer
following default by Barrick of the pledge. No notice shall be required of such pledge.


(c)Certificates
evidencing the Shares shall not contain any legend (including the legend set forth in Section 4.1(b)): (i) whenever the Shares
are registered for resale under the Securities Act, or (ii) following a sale or transfer of such Shares pursuant to Rule 144 (assuming
the transferor is not an Affiliate of the Company), or (iii) if such legend is not required under applicable requirements of the
Securities Act (including judicial interpretations and pronouncements issued by the Staff of the Commission). Following such time
as restrictive legends are not required to be placed on certificates representing the Shares, the Company will, no later than three
Trading Days following the delivery by Barrick to the Company or the Company’s transfer agent of a certificate representing
such Shares containing a restrictive legend (endorsed or with stock power attached, signatures guaranteed, and otherwise in form
necessary to affect reissuance and/ or transfer), deliver or cause to be delivered to Barrick or its agent a certificate representing
such Shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions
to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section 4.1(c).


4.2             
Integration. The Company shall not, and shall use its best efforts to ensure that no Affiliate of the Company shall,
sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the
Securities Act) that would be integrated with the offer or sale of the Shares in a manner that would require the registration under
the Securities Act of the sale of the Shares to Barrick.


4.3             
Indemnification of Investors. In addition to the indemnity provided in the Option Agreement, the Company will indemnify
and hold Barrick and Barrick Bullfrog and their directors, officers, shareholders, partners, employees and agents (each, an “Barrick
Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses,
including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation
(collectively, “Losses”) that any such Barrick Party may suffer or incur as a result of or relating to any misrepresentation,
breach or inaccuracy of any representation, warranty, covenant or agreement made by the Company Rocky Mountain in any Transaction
Document. In addition to the indemnity contained herein, the Company will reimburse each Barrick Party for its reasonable legal
and other expenses (including the cost of




    	 



    	 



    

any investigation, preparation and travel
in connection therewith) incurred in connection therewith, as such expenses are incurred.


4.4             
Rule 144 Compliance. With a view to making available to the holders of Shares the benefits of Rule 144 under the Securities
Act and any other rule or regulation of the Commission that may at any time permit a holder to sell securities of the Company to
the public without registration, the Company shall:


(a)               
make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act,
at all times after the Closing Date;


(b)              
use reasonable best efforts to file with the Commission in a timely manner all reports and other documents required of the
Company under the Securities Act and the Exchange Act; and


(c)               
furnish to any holder so long as the holder owns any of the Shares that have the status of “restricted securities”
within the meaning of Rule 144, promptly upon request, a written statement by the Company as to its compliance with the reporting
requirements of Rule 144 and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of
the Company, and such other reports and documents so filed or furnished by the Company as such holder may reasonably request in
connection with the sale of such Shares without registration.

charges and penalties and the cost of transportation to any processing or refining facility, insurance premiums, sampling and assaying
charges incurred after concentrates have left the concentrator and all appropriate sales taxes. In no case shall the cost of mining,
transportation, concentrating, smelting and refining costs, or administrative costs be deducted from the selling price in the calculation
of Royalty. If any portion of the precious metals or other minerals or products extracted and derived from the ore mined from the
Properties are sold to an Affiliate of Grantee or treated by a facility owned or controlled by Grantee, the actual gross proceeds
received shall be deemed to be an amount equal to what could be obtained from a non-Affiliate or purchaser or facility not so owned
or controlled by the Grantee, which would have been incurred had the material been sold or treated to such third party.


The Royalty reserved herein shall be
subject to the following:




    	 



    	 



    

1.PAYMENT OF ROYALTY


a.Frequency
of Payment of Royalty. Grantee shall pay the Royalty within thirty (30) business days after the sale proceeds are received
during each calendar quarter from any purchaser of minerals or other materials mined from the Properties.


b.Method
of Making Payments. All payments required hereunder may be mailed or delivered to any single depository as Grantor may instruct.
The Grantee will have no responsibility as to the division of the Royalty payments among parties constituting the Grantor and if
the Grantee makes a payment or payments on account of the Royalty in accordance with the provisions of this instrument, it will
have no further responsibility for distribution of the Royalty. All charges of the agent, trustee or depository will be borne solely
by the parties receiving payments of Royalty. The delivery or the deposit in the mail of any payment hereunder on or before the
due date thereof shall be deemed timely payment hereunder.


2.RECORDS AND REPORTS


a.Records,
Inspection and Audit. Within ninety (90) days following the end of each calendar year, commencing with the year in which the
Property is brought into commercial production (not inclusive of any bulk sampling programs), the Grantee shall deliver to Grantor
a statement of the Royalty paid for said calendar year. The Grantor shall have the right within a period of three (3) months from
receipt of such statements to inspect the Grantee’s books and records relating thereto and to conduct an independent audit
of such books and records at its own cost and expense.


b.Objections.
If Grantor does not request an inspection of Grantee’s books and records during the three-month period referred to in the
preceding paragraph, all payments of Royalty for the annual period will be considered final and in full satisfaction of all obligations
of the Grantee with respect thereto. If Grantor disputes any calculation of Royalty, Grantor shall deliver to the Grantee a written
notice (the “Objection Notice”) describing and setting forth a specific objection within sixty (60) days after receipt
by the Grantor of the final statement. If such audit determines that there has been a deficiency or an excess in the payment made
to the Grantor, such deficiency or excess will be resolved by adjusting the next payment due hereunder. The Grantor will pay all
the costs and expenses of such audit unless a deficiency of five (5%) percent or more of the amount due is determined to exist.
The Grantee will pay the costs and expenses of such audit if a deficiency of five (5%) percent or more of the amount due is determined
to exist. All books and records used and kept by the Grantee to calculate the Royalty due hereunder will be kept in accordance
with generally accepted accounting principles.


3.INUREMENT


The Royalty reserved herein shall run
with the land and be binding on all subsequent owners of the Property, including any amendments, relocations, patents of the same
or additional or alternative rights to mine as may be conferred by any changes in the mineral laws of the United States.




    	 



    	 



    

4.NOTICES


All notices required or permitted to
be given hereunder shall be given in writing and shall be sent by the parties by registered or certified mail, telex, facsimile
transmission or by express delivery service to the address set forth in the identification of the parties in the headings of this
Quitclaim Deed and Reservation of Royalty Interest or to such other address as either party may later designate by like notice
to the other. All notices required or permitted to be given hereunder shall be deemed to have been given upon the earliest of (1)
actual receipt, (2) acknowledgment in any form of receipt of telex or facsimile transmission, (3) the business day next following
deposit with an express delivery service, properly addressed, or (4) seventy-two (72) hours after deposit with the U.S. Mail, properly
addressed with postage prepaid. E-mail shall also be an acceptable and legal form of communications between the Parties.


5.ASSIGNMENTS BY GRANTOR


Grantor may transfer, pledge, mortgage,
charge or otherwise encumber all or any part of its right, title and interest in and to its Royalty reserved hereunder; provided,
however, that Grantee shall be under no obligation to make its payments hereunder to such assignee, transferee, pledgee or other
third party until Grantee’s receipt of Notice concerning the assignment or transfer.


6.COMMINGLING ORE


Grantees shall have
the right to commingle ores from the Properties with ores from other properties; provided that Grantee weighs, samples, and accounts
Grantor’s ores in accordance with sound mining and metallurgical practices.


7.INTERPRETATION


a.Governing
Law; Venue. The provisions and interpretation of this Quitclaim Deed and Reservation of Royalty Interest shall be governed
by the laws of the State of Nevada without regard to conflicts of laws principles. Any dispute concerning this Quitclaim Deed and
Reservation of Royalty Interest shall be adjudicated in either the state or federal courts in and for the State of Nevada.


b.Invalidity
of Provisions. If any term or other provision of this Quitclaim Deed and Reservation of Royalty Interest is invalid, illegal
or incapable of being enforced by any rule of law, or public policy, all other conditions and provisions of this Quitclaim Deed
and Reservation of Royalty Interest shall nevertheless remain in full force and effect so long as the economic and legal substance
of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination
that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good
faith to modify this Quitclaim Deed and Reservation of Royalty Interest so as to effect the original intent of the parties as closely
as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

industry. The arbitrator may engage professional mining consulting firms to assist in analysis of the facts presented by the Parties
at the sole discretion of the arbitrator. If the Parties are unable to agree on the identity of a single arbitrator within 10 days
of any request for arbitration, then each Party shall select one arbitrator and the two arbitrators shall select a third, all within
30 days of the relevant request for arbitration. All decisions and awards shall be made by a majority of the three arbitrators.


 


3.Notice of demand for arbitration shall

shall be referred to the arbitrator or arbitrators, whose determination on such issues shall be final and conclusive. Disclosure

all arbitration proceedings shall be concluded within 90 days after the notice of demand for arbitration, and the arbitration award
shall be rendered in writing within 30 days after the conclusion of the arbitration hearing.
