A. Exc1usive Right to and Use of Surface.
Lessor specifically reserves the rights of unlimited use of, and of all ingress and egress upon, the surface for grazing livestock and
sheep, and for all similar purposes, as granted under Part A above. Lessee expressly warrants and covenants that Lessor’s

or disturb such grazing activities. In the event of surface disturbance, Lessee agrees to reclaim said surface displacement in a reasonable
time and manner.

 

B. Other Purposes. Lessor retains the right
to use or lease the surface of said Leased Premises, or any part thereof at any time, and for any purpose, other than for exploration
and development of underground minerals and ores and underground mining, which other use and leasing of said surface shall at all times
be subject to the dominant mining rights and privileges herein specifically granted to Lessee.

 

C. Inspection. Lessor retains the right
at all times during the Term of this Part B of the Combined Lease Agreement to go upon said Leased Premises and every part thereof
for the purpose of inspecting the same and of ascertaining whether or not Lessee, and those holding by and under Lessee, are carrying
out the terms, covenants, and agreements contained in this Combined Lease Agreement.

 

4. PRODUCTION ROYALTY.
A.     “Net Smelter Return Royalty;” Definition. Lessee agrees to pay to Lessor Two
Percent (2%) Net Smelter Return Royalty (herein, “Production Royalty”) on minerals, ores and products therefrom,
produced and sold from the Leased Premises during the Term of Part B of this Combined Lease Agreement. As used herein, the term
 “Production Royalty” means 2% of the amount paid to Lessee by a smelter, refiner, or other purchaser for ores, metals,
concentrates, precipitates, cathodes, leachate solutions, or other products mined and sold by Lessee from the Leased Premises during
the Term of Part B of this Combined Lease Agreement, less a deduction of all costs paid by Lessee for sampling and assaying,
milling, concentrating, processing, smelting and refining the mined ores to yield a saleable product, and less the cost of all
transportation (including packaging and insurance) of ore and products from the Leased Premises to the point of sales, and less any
taxes or other levies imposed by government upon the mining, production or sale of minerals or products therefrom.

 

B. Definition of “Minerals” and
 “Product.” As used herein, “minerals” means all valuable minerals or ores containing metals or other valuable
constituents, non-metallic industrial metals or rocks, clay, soil sand and gravel; “product” means any valuable metal substance
or material produced from or in connection with the mining and/or processing of metalliferous minerals, and excludes petroleum, coal
or hydrocarbon fuels. Lessor shall be entitled to Production Royalty only if minerals and ores are removed from property owned by the
Lessor.

 

C. Calculation of Royalty. All Production
Royalties shall be calculated on a calendar-quarter basis, and shall be paid to Lessor following the end of each quarter, within thirty
days after receipt by Lessee of final payment during that quarter for such ores or products. Production Royalty shall not be paid on
ores or products which are stockpiled upon the Leased Premises, or which are not recovered and sold by the Lessee or for which payment
is not made to the Lessee by the purchaser thereof. Failure to pay Production Royalty to Lessor when due shall be grounds for Lessor
to cancel Part B of the Combined Lease Agreement if payment is not made within 30 days after Lessor delivers written notice to Lessee.

agreed that ore mined and taken from the Leased Premises shall be weighed and the weight thereof shall be entered in due form in books
kept for such purposes by Lessee. It is agreed that the term “ton” as used herein means a ton of 2,000 pounds as shown by

without unnecessary waste or injury to the Leased Premises. Improvements or equipment remaining on the Leased Premises after one hundred
eighty days shall become the property of Lessor.

PART C: TERMS & CONDITIONS APPLICABLE TO PARTS
A and B

 

This component of the Combined Lease Agreement is by and between
the Okelberrys and Hansen & Companies, and expresses the general terms and conditions applicable to Part A and Part B,
above.

 

1. TITLE AND INTEREST. A. Covenant of
Title. Each party hereby represents and covenants to the other that to the best of its knowledge and belief that it holds the full
surface and mineral title to the leasehold estate in undivided, fee-simple interest, and it has not assigned or encumbered the surface
or mineral title, as applicable. Each party agrees that the other may, as applicable, pay and discharge any taxes, mortgages or other
liens existing, levied or assessed on or against the applicable leasehold property, and shall have the right but not the obligation to
cure any title defects. Each party shall cooperate with the other party and shall execute all documents and take such steps as either
party may reasonably request in connection with such action.

ENT       2506:2016
PG 5 of 8

 

B. Other Than Entire Fee-Simple Interest.
In the event that the true and actual surface and/or mineral interest owned by a party in a leasehold estate is anything less than the
entire and undivided fee simple title as specified herein, then the rights and privileges shall be applicable proportionately. In the
event that a party does not own the surface estate and the other party is obligated to pay fee or surface damages to the true and actual
owner, then the full amount paid shall be set off against any payments due.

 

2. COMPLIANCE WITH LAW. Each party covenants
and agrees during the continuance of this Combined Lease Agreement that it will fully comply with all the provisions, terms and conditions
of all federal, state and local laws, regulations, ordinances and rules.

 

3. NOTICES. It is agreed that any notice
required or permitted to be given under the provisions of this Combined Lease Agreement may be delivered in person or sent by private
courier or certified U.S. Mail (return receipt requested) to the address set forth at the beginning of this Agreement, or to such other
address as a party may indicate in writing to the other, and such delivery shall be deemed sufficient and in full compliance with the
terms of this Agreement. Notices sent by private courier or certified mail shall be considered delivered on the date set forth in the
receipt, or when unsuccessful delivery was attempted.

 

4. ASSIGNMENT. Either party shall have
the right to assign this lease as to all or part of the interest of the other, and as to all or any part of the leasehold estates covered
hereby.

 

5. TAXES. During the period of this Combined
Lease Agreement, each party shall separately pay the property taxes levied or assessed upon or against its own property.

 

6. DEFAULT AND TERMINATION. A. Default;
Procedures Before Termination or Forfeiture. It is agreed that this Combined Lease Agreement shall not be deemed forfeited or terminated
for failure by one party to perform in whole or in part any of the covenants until after thirty (30) days following delivery of written
notice of default to that party. If default is contested, and the notified party shall have been finally judicially determined that such
default or failure exists, then the defaulting party shall be given a reasonable time therefrom to cure the default or failure, or otherwise
comply with any such covenant. Only upon failure to cure shall termination occur.

 

B. Termination By Surrender. A party may
surrender its applicable rights under either Part A or Part B, and thereby terminate that applicable Part of this Combined
Lease Agreement at any time by delivering written notice to the other party. In such case, each party may retain the benefit of performance
of all past obligations as full liquidation damages. The remaining Parts shall continue in force unless and until the parties have surrendered
both Part A and Part B. Upon surrender of both Parts, all rights and privileges, on the one hand, and all obligations and commitments
on the other hand, shall immediately cease.

 

7. ENFORCEMENT. All prior agreements are
revoked and are hereby deemed null and void. This Agreement shall be applicable to all successors of the parties and shall be governed
by the laws and construed by the courts and administrative agencies of the State of Utah. Should it become necessary to enforce any provision
of this Combined Lease Agreement, the party prevailing in such action or effort shall be entitled to recover all direct costs incurred
to enforce its rights, including reasonable attorney, expert and witness fees.
