FOURTH AMENDMENT TO CREDIT AGREEMENT

THIS FOURTH AMENDMENT TO CREDIT AGREEMENT, dated as of September 20, 2019 (this "Amendment"), is by and among SIFCO Industries, Inc., an Ohio corporation (“SIFCO”), and Quality Aluminum Forge, LLC, an Ohio limited liability company (“Quality Forge” and, together with SIFCO, collectively, the “Borrowers” and each, individually, a “Borrower”), any other Loan Parties party hereto, and JPMorgan Chase Bank, N.A., a national banking association (the “Lender”).

RECITALS

A.    The Borrowers, any other Loan Parties party thereto, and the Lender are parties to a Credit Agreement dated as of August 8, 2018 (as it may be amended or modified from time to time, the “Credit Agreement”). 

B.    The Borrowers and any other Loan Parties desire to amend the Credit Agreement, and the Lender is willing to do so in accordance with the terms hereof.

TERMS

In consideration of the premises and of the mutual agreements herein contained, the parties agree as follows:

ARTICLE I.  AMENDMENTS.  Upon fulfillment of the conditions set forth in Article III hereof, the Credit Agreement shall be amended effective as of the date hereof as follows:

1.1    Section 1.05 of the Credit Agreement is restated as follows:

SECTION 1.05     Interest Rates; LIBOR Notifications.  The interest rate on Eurodollar Loans is determined by reference to the LIBO Rate, which is derived from the London interbank offered rate.  The London interbank offered rate is intended to represent the rate at which contributing banks may obtain short-term borrowings from each other in the London interbank market.  In July 2017, the U.K. Financial Conduct Authority announced that, after the end of 2021, it would no longer persuade or compel contributing banks to make rate submissions to the ICE Benchmark Administration (together with any successor to the ICE Benchmark Administrator, the “IBA”) for purposes of the IBA setting the London interbank offered rate. As a result, it is possible that commencing in 2022, the London interbank offered rate may no longer be available or may no longer be deemed an appropriate reference rate upon which to determine the interest rate on Eurodollar Loans.  In light of this eventuality, public and private sector industry initiatives are currently underway to identify new or alternative reference rates to be used in place of the London interbank offered rate.  In the event that the London interbank offered rate is no longer available or in certain other circumstances as set forth in Section 2.13 of this Agreement, the Lender will notify the Borrower Representative in advance of any change to the reference rate upon which the interest rate on Eurodollar Loans is based.  However, the Lender does not warrant or accept any responsibility for, and shall not have any liability with respect to, the administration, submission or any other matter related to the London interbank offered rate or other rates in the definition of “LIBO Rate” or with respect to any alternative or successor rate thereto, or replacement rate thereof, including without limitation, whether the composition or characteristics of any such alternative, successor or replacement reference rate, as it may or may not be adjusted, will be similar to, or produce the 

1

same value or economic equivalence of, the LIBO Rate or have the same volume or liquidity as did the London interbank offered rate prior to its discontinuance or unavailability. 

1.2    The following new Section 2.13(c) is added to the Credit Agreement:

(c)    If at any time the Lender determines (which determination shall be conclusive absent manifest error) that (i) the circumstances set forth in clause (a)(i) have arisen and such circumstances are unlikely to be temporary or (ii) the circumstances set forth in clause (a)(i) have not arisen but either (w) the supervisor for the administrator of the LIBO Screen Rate has made a public statement that the administrator of the LIBO Screen Rate is insolvent (and there is no successor administrator that will continue publication of the LIBOR Screen Rate), (x) the administrator of the LIBO Screen Rate has made a public statement identifying specific date after which the LIBO Screen Rate will permanently or indefinitely cease to be published by it (and there is no successor administrator that will continue publication of the LIBO Screen Rate), (y) the supervisor for the administrator of the LIBO Screen Rate has made a public statement identifying a specific date after which the LIBO Screen Rate will permanently or indefinitely cease to be published or (z) the supervisor for the administrator of the LIBO Screen Rate or a Governmental Authority having jurisdiction over the Lender has made a public statement identifying a specific date after which the LIBO Screen Rate may no longer be used for determining interest rates for loans, then the Lender and the Borrowers shall endeavor to establish an alternate rate of interest to the LIBO Rate that gives due consideration to the then prevailing market convention for determining a rate of interest for bank loans in the United States at such time, and shall enter into an amendment to this Agreement to reflect such alternate rate of interest and such other related changes to this Agreement as may be applicable (but, for the avoidance of doubt, such related changes shall not include a reduction of the Applicable Rate).  Until an alternate rate of interest shall be determined in accordance with this clause (c) (but, in the case of the circumstances described in clauses (ii)(w), (ii)(x) or (ii)(y) of the first sentence of this Section 2.13(c), only to the extent the LIBO Screen Rate for such Interest Period is not available or published at such time on a current basis), (1) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective and any such Eurodollar Borrowing shall be repaid or converted into a CBFR Borrowing on the last day of the then current Interest Period applicable thereto, and (2) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as a CBFR Borrowing; provided that, if such alternate rate of interest shall be less than zero, such rate shall be deemed to be zero for the purposes of this Agreement.

1.3    Section 5.14(a) of the Credit Agreement is amended by adding the following to the end thereof: “In connection therewith, the Lender shall have received all documentation and other information regarding such newly formed or acquired Subsidiaries as may be required to comply with the applicable “know your customer” rules and regulations, including the USA Patriot Act.”

1.4    The following new Section 6.03(i) is added to the Credit Agreement:

(i)    No Loan Party will, nor will it permit any Subsidiary to, consummate a Division as the Dividing Person, without the prior written consent of Lender.  Without limiting the foregoing, if any Loan Party that is a limited liability company consummates a Division (with or without the prior consent of Lender as required above), each Division Successor shall be required to comply with the obligations set forth in Section 5.14 and the other further assurances obligations set forth in the Loan Documents and become a Loan Party under this Agreement and the other Loan Documents.

1.5    The following definitions are added to the Definitions Schedule to the Credit Agreement:

“Dividing Person” has the meaning assigned to it in the definition of “Division.” 

2

“Division” means the division of the assets, liabilities and/or obligations of a Person (the “Dividing Person”) among two or more Persons (whether pursuant to a “plan of division” or similar arrangement), which may or may not include the Dividing Person and pursuant to which the Dividing Person may or may not survive. 

“Division Successor” means any Person that, upon the consummation of a Division of a Dividing Person, holds all or any portion of the assets, liabilities and/or obligations previously held by such Dividing Person immediately prior to the consummation of such Division.  A Dividing Person which retains any of its assets, liabilities and/or obligations after a Division shall be deemed a Division Successor upon the occurrence of such Division. 

1.6    The following definition is added to the Borrowing Base Schedule to the Credit Agreement:

“Combined Borrowing Base” means, without duplication, (i) the Borrowing Base, plus (ii) the “Borrowing Base” as defined in the Export Credit Agreement.

1.7    The definition of “EBITDA” in Section (A) of the Financial Covenants Schedule to the Credit Agreement is amended by replacing the period at the end of such definition with “, plus”, and adding the following new paragraph to the end of such definition:

(c)         to the extent not otherwise included in the determination of Net Income for such period, the amount of any cash proceeds of any business interruption insurance policy in an amount representing the earnings for such period that such proceeds are intended to replace (it being agreed that the proceeds of any business interruption insurance policy shall be included in the determination of Net Income for any such period only if cash proceeds are actually received and permitted to be included in accordance with GAAP).

1.8    Section (B) of the Financial Covenants Schedule to the Credit Agreement is restated as follows:

(B)     Financial Covenant.

Fixed Charge Coverage Ratio.  The Borrowers will not permit the Fixed Charge Coverage Ratio to be less than 1.1 to 1.0 as of the last day of any calendar month; provided that the Fixed Charge Coverage Ratio will not be tested unless:

(i)     a Default has occurred and is continuing or 

(ii)     (a) at any time on or before June 30, 2020, Combined Availability was less than or equal to the greater of (1) 10% of the lesser of (x) the Combined Borrowing Base or (y) the Combined Commitments minus the Availability Block, if applicable, and (2) $2,000,000, for three or more Business Days in any consecutive 30 day period (with the Fixed Charge Coverage Ratio calculated as of the end of the month for which the Lender has most recently received financial statements), or     

(b) at any time on or after July 1, 2020, Combined Availability was less than or equal to 12.5% of the Combined Commitments for three or more Business Days in any consecutive 30 day period (with the Fixed Charge Coverage Ratio calculated as of the end of the month for which the Lender has most recently received financial statements).
        
ARTICLE II.  REPRESENTATIONS.  Each Loan Party represents and warrants to the Lender that:

3

2.1    This Amendment has been duly executed and delivered by such Loan Party and constitutes a legal, valid and binding obligation of such Loan Party, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors' rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.  

2.2    After giving effect to this Amendment, the representations and warranties contained in Article III of the Credit Agreement and in the other Loan Documents are true in all material respects on and as of the date hereof with the same force and effect as if made on and as of the date hereof (it being understood and agreed that any representation or warranty which by its terms is made as of a specified date shall be required to be true and correct in all material respects only as of such specified date, and that any representation or warranty which is subject to any materiality qualifier shall be required to be true and correct in all respects). 

2.3    After giving effect to this Amendment, no Default exists or has occurred and is continuing, and no Default will be caused after giving effect to this Amendment.

ARTICLE III.  CONDITIONS OF EFFECTIVENESS.  This Amendment shall become effective as of the date hereof when each of the following conditions is satisfied:
    
3.1    The Loan Parties and the Lender shall have signed this Amendment.

3.2    The Lender shall have received such other documents, if any, as the Lender may request.

ARTICLE IV.  MISCELLANEOUS.

This Amendment shall be governed by and construed in accordance with the internal laws and not the law of conflicts of the State of Ohio, but giving effect to federal laws applicable to national banks.

toward the Purchase Price prior to July 9, 2019, and Buyer has made a non-refundable deposit of $3,500,000 in the form of Series

(b) The Membership Interests will be delivered to
Buyer proportionately to the cash consideration received by Seller from Buyer.

 

(i) At Closing, Seller will deliver a 50.33% Membership
Interest to Buyer, reflecting $7,550,000 total cash consideration through Closing; and

this Agreement.

Once the Debenture has been repaid, Seller shall have the right to record the Deed of Trust as a first priority security interest.

 

     

     

    

 

(iii) As long as the Loan is outstanding, Buyer shall
not, create, incur, assume or permit to exist any Indebtedness (as defined below) other than convertible notes issued by Buyer
prior to the Closing Date with aggregate principal amount of $14 million or less. “Indebtedness” means, without duplication,
(a) all obligations for borrowed money or with respect to deposits or advances of any kind, (b) all obligations evidenced by bonds,
debentures, notes or similar instruments, (c) all obligations upon which interest charges are customarily paid, (d) all obligations
under conditional sale or other title retention agreements relating to property acquired, (e) all obligations in respect of the

course of business), (f) all obligations secured by any Lien on property owned or after acquired, (g) all guarantees of obligations
of others, (h) all capital lease obligations, (i) all obligations, contingent or otherwise, as an account party in respect of letters
of credit and letters of guaranty, (j) all obligations, contingent or otherwise, in respect of bankers’ acceptances, (k)
all obligations under any swap agreement or under any similar type of agreement, (l) all obligations under sale and leaseback transactions.
Notwithstanding the preceding, Buyer shall be permitted to incur Indebtedness described in clauses (c) through (l) above not to
exceed $1,000,000 in the aggregate (such Indebtedness, “Permitted Debt”).

 

(iv) The following events or circumstances shall
be events of default under the Loan: (a) the Buyer shall fail to pay any principal under the Loan when due and payable thereunder;
or (b) the Buyer shall fail to pay any interest or any other amount under the Loan when due and payable thereunder; or (c) a receiver,
trustee or other similar official shall be appointed over the Buyer or a material part of its assets and such appointment shall
remain uncontested for twenty (20) days or shall not be dismissed or discharged within sixty (60) days; or (d) the Buyer shall
become insolvent or generally fails to pay, or admits in writing its inability to pay, its debts as they become due, subject to
applicable grace periods, if any; or (e) the Buyer shall make a general assignment for the benefit of creditors; or (f) the Buyer
shall file a petition for relief under any bankruptcy, insolvency or similar law (domestic or foreign); or (g) an involuntary proceeding
shall be commenced or filed against the Buyer; or (h) the Buyer shall fail to convert CP Shares within 30 days of Seller requesting
for a conversion thereof; or (i) the Buyer shall breach or fail to comply with its other obligations, commitments, covenants, representations
or warranties for more than 20 days under the Loan, reimbursement obligations surviving the termination of the Option Agreement,
obligations to reimburse any interest payable under Seller’s debenture, obligations to reimburse amounts payable by Seller
to Northern Comstock LLC or the Transaction Documents. If an event of default occurs under the Loan and Buyer fails to remedy such
violation within thirty (30) days following notice from Seller, then Seller shall have and be entitled to exercise, in its sole
discretion, any of the remedies available to a secured lender under Nevada law and any of the remedies set forth below. In case
of any such event of default, the Loan shall thereafter bear interest at a rate of twelve percent (12%) per annum, compounding
on a monthly basis until paid in full. The Seller may foreclose and sell any or all of the Membership Interests theretofore owned
by Buyer and any or all assets owned by the Company in order to pay off the Loan. In addition, the Seller shall have a right to
terminate any of the Transaction Documents.

 

     

     

    

 

(v) Buyer shall be permitted to prepay all or any
part of the balance outstanding under the Loan at any time without penalty or premium. Buyer and Seller hereby agree that Buyer
shall pay the cash required to make payments hereunder from the proceeds of equity raises, royalty sales and/or other third party
funding agreements, whether in one transaction or a series of transactions (collectively, a “Capital Raise”). Buyer
covenants and agrees that if Buyer receives any proceeds from any Capital Raise in excess of $6.5 million, then Buyer shall cause
50% of such proceeds to be immediately paid to Seller and used to prepay the Loan. Except for Permitted Debt, Buyer covenants and
agrees that Buyer shall not use the proceeds of any Capital Raise for any other purpose other than making payments to Seller, permitting,
exploration drilling, a preliminary economic assessment and costs directly attributable to such Capital Raise. Buyer covenants
and agrees that Buyer shall not commence production until the Loan is repaid in full.

 

(vi) As long as the Loan is outstanding, Buyer and
Seller covenant and agree to keep the Lucerne Properties at all times free and clear of all Liens, except for Liens securing the
Debenture or otherwise described in the Schedules to this Agreement. Seller covenants and agrees to use Loan payments received
to pay off amounts under the Debenture, per the terms of the Debenture, until the Debenture is repaid in full.

 

(d) In addition, on the date that the Loan is paid in full,
if permitted, Seller will assign all of its interest (the ”Northern Comstock Interest“) in Northern Comstock LLC, a
Nevada limited liability company (“Northern Comstock“) to the Company. If permitted, Seller may elect to assign the
Northern Comstock Interest at an earlier date than the date that the Loan is paid in full, in the sole discretion of Seller. Commencing
as of the Closing Date, Buyer hereby agrees to forever assume and unconditionally guarantee the full and punctual payment, fulfilment
and performance of all obligations and benefits of Seller under the current Northern Comstock LLC Operating Agreement (the “Existing
NC Operating Agreement”). The guarantee in the preceding sentence (the “Guarantee”) shall be an absolute and
continuing guarantee of performance and payment and shall not in any way be conditional or contingent upon any demand of Northern
Comstock or its members to collect or require anything from Seller or any stated obligations of Seller under the Existing NC Operating
Agreement (including, without limitation, section 13.5 of such agreement) or upon any other action, occurrence or circumstance
whatsoever. Without limiting the generality of the foregoing, the Guarantee shall not be released, discharged or otherwise affected
by:

 

     

     

    

 

(i) any extension, renewal, settlement, compromise,
waiver or release in respect of any obligation of any party under the Existing NC Operating Agreement, by operation of law or otherwise;

 

(ii) any modification or amendment of or supplement
to the Existing NC Operating Agreement;

 

(iii) any change in the organizational existence,
structure or ownership of Buyer or the Company, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting
Buyer, the Company or their respective assets or any resulting release or discharge of any obligation of Buyer or the Company;

 

(iv) the existence of any claim, set-off or other
rights which Buyer or Company may have at any time against Seller or Northern Comstock or its members or its manager;

 

(v) any invalidity or unenforceability relating to
or against Buyer for any reason of this Agreement, the Existing NC Operating Agreement or any provision of applicable law or regulation
purporting to prohibit the payment by Buyer of any amounts payable pursuant to the Guarantee; or

 

(vi) any other act or omission to act or delay of
any kind by Buyer, the Company, Seller, Northern Comstock or any other person or any other circumstance whatsoever which might,
but for the provisions of this paragraph, constitute a legal or equitable discharge of or defense to Buyer’s obligations
pursuant to the Guarantee.

 

For so long as Buyer fulfills its obligations with
respect to the Guarantee, Seller hereby agrees to (i) hold legal ownership of the Northern Comstock Interest and (ii) exercise
its rights with respect to the Northern Comstock Interest under Existing NC Operating Agreement at Buyer's direction.

 

(e) The Company owns (or will following the Closing will own)
fee property, patented mining claims, and unpatented mining claims, and through the Seller’s membership in Northern Comstock
LLC, has indirect ownership or exclusive control of additional fee property, patented mining claims, unpatented mining claims,
and leasehold interests, collectively known as the Lucerne project, as detailed in Exhibit A (the “Lucerne Properties”).
Effective as of the Closing Date, each of the Parties hereby agree that the Company will pay Seller a 1.5% NSR royalty on all minerals
produced from the Lucerne Properties, as detailed in Exhibit B (the “NSR Royalty Agreement”).

 

(f) Effective as of the Closing Date, the Company will assume
all current reclamation liability on the Lucerne Properties and all future liability from the Company’s operations on the
Lucerne Properties. The Company will assume all costs of maintaining the Federal, State, and County permits and reclamation bonds
on the Lucerne Properties.

 

3.

follows:

sale of the Membership Interests (the “Closing”) will take place at a mutually acceptable time and place selected by

Seller shall deliver, or cause to be delivered, the following deliverables:

 

(a) Buyer shall have delivered the Closing Cash Consideration
remaining to be paid after reduction by the amount of previously delivered non-refundable deposits into a bank account designated
by Seller by wire transfer of immediately available funds, which shall not delivered to Seller until all other closing conditions
have been met by the Parties; and

 

(b) Unless previously executed and delivered, Buyer
shall execute and deliver to Seller each of:

 

(i) the Deed of Trust;

(ii) the NSR Royalty Agreement;

(iii) the Operating Agreement for the Company in the
form attached hereto as Exhibit I (the “Operating Agreement”);

(iv) the Lease Option Agreement;

(v) the Mineral Exploration and Mining Lease; and

(vi) a certification naming Buyer’s representatives
who authorize and consent to the Company’s entry into the agreements effective as of the Closing Date, together, with this
Agreement, the Deed of Trust, the NSR Royalty Agreement, the Lease Option Agreement, the Mineral Exploration and Mining Lease,
and the Operating Agreement (the “Transaction Documents”), in each case duly executed by Buyer and/or the Company,
as the case may be.

 

(c) Seller shall retain its membership interest in
Northern Comstock, and have an obligation to Buyer to maintain all rights and agreements under the Existing NC Operating Agreement,
for so long as Buyer fulfills its obligations with respect to the Guarantee, including, without limitation, Buyer’s obligation

“Termination Date”) and prior to the Closing, by Buyer, if (A) the Closing shall not have been consummated on or before
the Termination Date and (B) the failure to consummate the Closing on or before the Termination Date did not result from the failure
by Buyer to perform or comply with any covenant or agreement contained in this Agreement required to be performed or complied with

5.                 
Supersedence of Amendments Related to Deposits. All provisions related to purchase price deposits set forth in each
amendment to the Purchase Agreement are hereby superseded by the provisions of Section 1.2(a) of the Purchase Agreement, as amended
hereby.

 

6.                 
Expense Reimbursement Obligations.

 

		a.	Buyer hereby agrees to pay in full all existing unpaid invoices under the Option Agreement and the Purchase Agreement issued

to Seller within 24 hours of receipt

 

		b.	Buyer acknowledges and agrees that Buyer is obligated to reimburse Seller for “Net Lease Maintenance Costs” (as
defined in the Lease Option Agreement), as and when indicated in the Lease Option Agreement.

 

		c.	(i) Buyer and Seller hereby agree to execute and deliver the Mineral Exploration and Mining Lease Agreement (the “Mining
Lease”), attached as Exhibit E. (ii) Section 1.3 (a) of the Purchase Agreement is amended so that the second sentence
reads, “Effective as of the September 16, 2019, Seller shall also agree to lease additional mining properties in Storey County

Buyer acknowledges and agree that Buyer shall pay Seller a quarterly lease fee of $10,000 in advance (escalating 10% each year)
under the Mining Lease and Buyer shall assume all costs associated with the leased property estimated in Exhibit E3 of the Mining
Lease. The costs, including property taxes, annual claim fees, environmental compliance, third party lease payments and advance
royalties shall be paid by Seller and timely reimbursed by Buyer. Buyer shall be directly responsible for any drilling or spending
commitments for the third party leases pursuant to the Mining Lease. Buyer and Seller also agree to modify the terms of the Mining

7.                 
Remedies Upon Default of this Amendment. If Buyer fails to comply with its obligations under this Amendment or fails
to make any payment required to be made under this Amendment and fails to remedy such violation within thirty (30) days following

remedies available to a secured lender under Nevada law and any of the remedies set forth below. In case of any such default, the
Seller shall have the right to treat such amounts as debt pursuant to promissory note (the “Deemed Promissory Note”)
with a principal amount equal to the sum of the amounts unpaid, bearing interest rate of twelve percent (12%) per annum, compounding
on a monthly basis until paid in full. The Deemed Promissory Note shall be secured by a deed of trust and/or other security interest
in the Lucerne Properties, the Membership Interests and all rights of the Company. In addition, the Seller shall have a right to
terminate any of the Transaction Documents (other than the Mining Lease).

 

8.                 
Termination of Option Agreement. The Option Agreement and all obligations of Seller and Buyer under the Option Agreement
are hereby terminated, canceled, null and void, as of the date hereof. To acknowledge the Termination, Buyer and Seller agree to
execute and deliver the Termination Agreement, attached as Exhibit H as of August 15, 2019. Commencing on the date hereof, Buyer
shall reimburse Seller for expenses or costs invoiced by Seller to Buyer for any and all support, services, goods and investment

9.                 
Exhibit Amendments.

 

		a.	Table A.1 of Exhibit A of the Purchase Agreement is hereby amended to eliminate property 800-001-13, the portion of the St.
Louis patent that extends into Lyon County. The description of property 800-001-09 shall be hereafter clarified to be only the
portion of the Green patent in Storey County. The portion of the Green patent extending into Lyon County is not included.

 

     

     

    

 

		b.	In addition, subject to an affiliate of Seller (e.g., Comstock Northern Exploration LLC) assuming the leases described in the
contents of Exhibit A.5: Fee and Patented Properties Controlled by Northern Comstock LLC through Sutro Lease, such leases shall
be added to the properties subject to the Mineral Exploration and Mining Lease.

 

10.

to the Conversion Rate in effect at the time of conversion.”

 

11.             
No Novation. Except as amended hereby, all of the terms and conditions of the Option Agreement and the Purchase Agreement
shall remain in full force and effect. Except as otherwise provided herein, Buyer and Seller acknowledge and agree that this Amendment

or termination of the obligations or liabilities under the Option Agreement or the Purchase Agreement.

 

12.             
Further Assurances. Each of Buyer and Seller shall, upon request from the other Party, execute and deliver such additional
documents, instruments, conveyances and assurances and take such further actions as may be reasonably required to carry out the
provisions hereof and give effect to the transactions contemplated by this Amendment and the documents to be delivered hereunder.

Exhibit E

Mineral Exploration and Mining Lease
Agreement

 

This Mineral Exploration and Mining Lease
Agreement (this "Agreement”) is made and entered into by and between Comstock Mining Inc., a Nevada corporation,
and Tonogold Resources, Inc., a Delaware corporation.

 

RECITALS

 

	A.	Comstock Mining Inc. is the owner of and in possession of certain patented and unpatented mining claims located in Storey County, Nevada, and controls additional fee property, patented mining claims, and unpatented mining claims through lease agreements with third parties. Said claims are collectively called the “Properties”, and are further described in Exhibit E1, and the lease agreements are further described in Exhibit E2 attached to and by this reference incorporated in this Agreement.

         

	B.	
        Comstock Mining Inc. (“Comstock”), Comstock
        Mining LLC (the “Company”), and Tonogold Resources Inc. (“Tonogold”) entered into a Membership
        Interest Purchase Agreement (the “Purchase Agreement”), dated January 24, 2019 whereby Comstock is selling its
        membership interest in the Company to Tonogold.

         

	C.	
        Tonogold (the “Lessee”) desires to lease
        the mining claims, and Comstock (the “Lessor”) is willing to grant to Lessee certain rights to lease the Properties
        for the purposes of mineral exploration, development, and eventual mining.

         

	D.	Lessee, at its expense, intends to explore the Property through geophysical surveys, geochemical sampling, and drilling, expending not less than $5 million in the first ten year term, and unless terminated, an additional $5 million in the second ten year term.

  

NOW THEREFORE, in consideration of their
mutual promises, the parties agree as follows:

 

		1.	Definitions: The following defined terms, wherever
used in this Agreement, shall have the meanings described below:

 

1.1       “Effective
Date” shall mean September 16, 2019.

 

1.2        “Lessor” shall
mean Comstock Mining Inc.

 

1.3       “Lessee”
shall mean Tonogold Resources, Inc.

 

1.4       “Lease Year”
shall mean each one (1) year period following the Effective Date and each anniversary of the Effective Date.

 

1.5       “Minerals”
shall mean gold, silver, platinum, antimony, mercury, copper, lead, zinc, and all other mineral elements, mineral compounds and
geothermal resources, whether the same are known to exist on the Properties or are discovered on the Properties after the Effective
Date and regardless of the method of extraction, mining or processing the same, whether known to exist or invented or developed
after the Effective Date.

 

1.6       “Properties” means the mining claims described
in Exhibit E1 of this Agreement.

 

1.7       “Ore” shall mean all Minerals or other materials
or substances from the Properties, the nature and composition of which, in the sole judgment of Lessee justifies either (a) mining
or removing from place and shipping and selling the same, or delivering the same to a processing plant for physical or chemical
treatment; or (b) leaching in place.

 

1.8       “Product”
shall mean: (a) all Ore shipped and sold prior to treatment; and (b) all concentrates, precipitates, refined metals, and any other
valuable minerals produced by or for Lessee from Ore.

 

     

     

    

 

1.9       “Net Smelter Return” or “NSR” shall
mean all Revenues from the sales of Products produced from the Properties, less shipping and Refining Costs pertaining to such
Revenues for the applicable calendar quarter. The calculation of Net Smelter Returns shall be made in accordance with accounting
principles and practices consistently applied in the mining industry in Nevada. For purposes of this definition, “Refining
Costs” means all costs and expenses of smelting and refining, including without limitation, all costs of assaying, sampling,
custom smelting, and refining, all independent representative and umpire charges, penalties, and other deductions, imposed or charged
by the refinery or smelter, as the case may be. If smelting or refining is carried out in facilities owned or controlled by Lessee
or its Affiliates, then the Refining Costs shall be the amount Lessee would have incurred if such smelting or refining were carried
out at facilities not owned or controlled by Lessee or its Affiliates then offering comparable services for comparable products
on prevailing terms.

 

1.10       “NSR Royalty” means the amounts payable by
Lessee to Lessor hereunder as provided in section 5.2.

 

1.11       “Revenues” means, for each sale of Products
during the applicable period, the sum of actual prices of Products received multiplied by the quantity of Products sold. If any
Products are diverted by the Company for commemorative coinage or any other value-added use, the Revenue will be calculated using
the spot price on a recognized exchange, on the date the Products are diverted.

 

		2.	Grant of Lease and Uses:

 

	 	2.1	Lease: Subject to the terms and conditions of this Agreement and to the extent permitted by applicable federal, state and local laws regulations and ordinances, Lessor agrees to lease the Properties to Lessee for mineral exploration and development, and the production, removal and sale of all Minerals, substances, metals, ore-bearing materials and rocks of every kind. 
	 	 	 
	 	2.2	Uses: Lessee is granted the right, insofar as Lessor may lawfully grant the right, to use the Properties, including but without being, limited to, the full right, authority and privilege of placing and using drill holes, excavations, open pit mines, openings, shafts, ditches and drains, and of constructing, erecting, maintaining, and using all buildings, structures, plants, roadways, pumps, pipelines, electrical power lines and facilities, stockpiles, waste plies, and all other improvements, property and fixtures for mining or removing Ores, Minerals or Product, or for any incidental activities, whether presently contemplated or known to be used in the exploration, development, and mining of Minerals.

 

	 	2.3	Third Party Leases: With respect to the third party leases, (a) Lessor grants only those rights explicitly enumerated in the respective leases, which are attached to this Agreement by reference, (b) Lessee agrees to comply with all conditions of such third party leases, and agrees to take all required actions to maintain the leases in good standing, and to take no action which would result in the termination of such leases by the third party owner and (c) Lessee acknowledges that some of the third party leases may expire prior to the termination date of this Agreement.  In such cases, the Parties agree to work together with the underlying owner to obtain a lease renewal on mutually acceptable terms.  If acceptable terms for a renewal cannot be reached, the Parties agree to remove the corresponding portion of the Properties from this Agreement.

 

		3.	Relationship of the
Parties:

 

	 	3.1	No Partnership: This Agreement shall not be deemed to constitute any party, in its capacity as such, the partner, agent or legal representative of any other party, or to create any partnership mining partnership or other partnership or other partnership relationship, or fiduciary relationship between them for any purpose whatsoever.

 

	 	3.2	Competition: Except as expressly provided in this Agreement, each party shall have the free and unrestricted right independently to engage in and receive the full benefits of any and all business endeavors of any sort whatsoever outside the Properties or outside the scope of this Agreement, whether or not competitive with the endeavors contemplated herein, without consulting the other or inviting or allowing the other therein. In particular, without limiting the foregoing, neither party to this Agreement shall have any obligation to the other as to any opportunity to acquire any money, property, interest or right offered to it outside the scope of this Agreement.

 

     

     

    

 

		4.	Term: The term of this Agreement shall be from
the Effective Date and,

 

		4.1	for ten (10) years (the “Exploration
Term") unless terminated or canceled pursuant to the terms of this Agreement. During the Exploration Term, Lessee commits
to total expenditures of at least $5 million for exploration; and

 

		4.2	following the Exploration Term this Agreement shall
automatically renew for an additional term of ten (10) years ("the Development Term") at the end of the Exploration
Term, so long as Lessee has documented total exploration expenditures during the Exploration Term of at least $5 million. During
the Development Term, Lessee commits to total expenditures for exploration, development, and technical reporting of at least $5
million, and will produce an economically viable mine plan, documented by an NI 43-101 compliant Feasibility Report, and will
produce a mutually agreed-upon schedule for placing the Properties into production; and

 

		4.3	so long as Lessee has documented total exploration
and engineering expenditures during the Development Term of at least $5 million and Lessee has created an economically viable
mine plan documented by an NI 43-101 compliant Feasibility report and mutually agreed-upon schedule, for as long following the
Development Term as development and permitting activities continue in compliance with a mutually agreed-upon schedule, or so long
as minerals are produced from the Properties or from other lands adjacent to or in the vicinity of the Properties (the “Extended
Term”). During the Extended Tem, operations shall be deemed conducted on a continuous basis unless and until a period
of 180 consecutive days elapses in which no exploration, development, mining, or processing operations are conducted on the Properties
or nearby lands, excluding periods of force majeure.

         

		5.	Payments: Lessee shall make the following payments
to Lessor,

  

	 	5.1	
        Lease Fee. Lessee shall pay Lessor a quarterly lease
        fee of $10,000 in advance. The lease fee will escalate 10% each year, on the anniversary date of this Agreement.

         

	 	5.2	
        Carrying Costs. Lessee shall pay or reimburse to Lessor
        all costs of owning the Properties, and all costs of maintaining the third party leases, including property taxes, annual claim
        fees, environmental compliance, third party lease payments and advance royalties, and any drilling or spending commitments for
        the third party leases. An estimate of these costs is attached as Exhibit E3 (the “Estimated Annual Costs”).

         

	 	5.3	NSR Royalty: In addition, Lessee shall pay to Lessor a royalty at the rate of 3% of the Net Smelter Returns from the Properties (the “Initial NSR Royalty”). After the first anniversary of Lessee commencing mining operations, the Initial NSR Royalty shall be reduced to 1.5% of the Net Smelter Returns from the Properties (the “Subsequent NSR Royalty”). The Initial NSR Royalty and Subsequent NSR Royalty shall be paid no later than 30 days after the end of each calendar quarter in which Products have been sold.  To be clear, this Initial NSR Royalty and Subsequent NSR Royalty is in addition to any royalties required by the third party leases, or other royalties that are recorded with the titles to any of the Properties. Lessee will be responsible for timely paying all such third party royalties directly.

 

	 	5.4	Method of Payment: All payments made by Lessee to Lessor shall be paid by wire transfer of immediately available funds to an account designated by Lessor.

 

	 	5.5	Audit: Lessor or its authorized agents shall have the right to audit and inspect Lessee’s accounts and records used in calculating the Net Smelter Return, which right may be exercised as to each payment at any reasonable time during a period of ninety (90) days from the date on which the payment was made by Lessee. If no such audit is performed during such period, such accounts, records and payments shall be conclusively deemed to be true, accurate and correct.
	 	 	 
	 	5.6	Assignment: If Lessee transfers any of its rights under this agreement, Transferee shall pay to Lessor an annual lease fee in the amount of  $12,000 (the "Annual Lease Fee") and agree to a work commitment on the Properties in the amount of $175,000 per year (the "Work Commitment"). This Annual Lease Fee and Work Commitment are in addition to the costs reimbursed to Lessor by Lessee, shown in Exhibit E3. Any assignment shall be subject to Section 24 below.

 

     

     

    

 

	6.	Compliance with the Law: The exercise by Lessee of any rights, privileges, grants and uses under this Agreement shall conform at all times with the applicable laws and regulations of the state in which the Properties are situated and the United States of America Lessee shall be fully responsible for compliance with all applicable federal, state and local reclamation statutes, regulations and ordinances relating to such work, all at Lessee’s cost, and Lessee shall indemnify and hold harmless Lessor from any and all claims, assessments, fines and actions arising from Lessee’s failure to perform the foregoing obligations. Lessor agrees to cooperate with Lessee in Lessee’s application for governmental licenses, permits and approvals, the costs of which shall be borne by Lessee.

 

		7.	Mining Practices; Inspection
of Data Reports; Insurance:

 

	 	7.1	Mining Practices: Lessee shall work the Properties in a miner-like fashion.

 

	 	7.2	Inspection of Data and Reporting: During the term of this Agreement, (a) Lessor shall have the right to examine reports and data regarding the Properties in Lessee’s possession during reasonable business hours and upon prior notice, provided, however, that the rights of Lessor to examine such data shall be exercised in a manner such that inspection does not unreasonably interfere with the operations of Lessee; (b) no less frequently than once per Lease Year, Lessee shall provide a report on exploration activities on the Properties, and a complete copy of all drilling data, maps, surveys and other exploration results obtained during that period, as well as documentation for all exploration, permitting, and development expenditures; and upon the termination of this Agreement, Lessee shall provide a final report of its activities on the Properties, and shall surrender all data on the Properties then in its possession. 

 

	 	7.3	
        Insurance: Lessee shall obtain and maintain
all worker’s compensation insurance as required by state law, as well as liability insurance and policies of insurance against
risks in amounts customarily obtained in similar mining operations and shall furnish Lessor proof of insurance prior to the commencement
of any operations. Lessee shall, at Lessee’s expense, during the term of this Agreement and any extension thereof, obtain
and maintain insurance which insures the Properties for public liability in amounts not less than those set out by the State of
Nevada and amounts reasonably satisfactory to Lessor, naming Lessor as an additional insured and protecting against all claims,
demands, actions, suits or causes of action and judgments, settlements or recoveries, for bodily injury, death or property damage
arising out of Lessee’s use or occupancy of or operations conducted upon the Properties. Lessee agrees to provide Lessor
with a certificate of insurance. The companies issuing such policies shall also be required to furnish the Lessor written notice
thirty (30) days prior to cancellation, termination, or other change of any such insurance. The Lessor shall periodically review
the level of the indemnification insurance and may require the amount of such insurance to be increased or decreased to reflect
changes in risk exposure. 

	 	 	 
	 	7.4	
        Reclamation: The exercise by Lessee of any rights, privileges,
        grants and uses under this Agreement shall conform at all times with the applicable laws and regulations of Storey County, the
        state of Nevada and the United States of America. Lessee shall be fully responsible for compliance with all applicable federal,
        state and local reclamation statutes, regulations and ordinances relating to such work, all at Lessee’s cost, and Lessee
        shall indemnify and hold harmless Lessor from any and all claims, assessments, fines and actions arising from Lessee’s failure
        to perform the foregoing obligations. This obligation will survive the termination of this Agreement until such time as all reclamation
        requirements have been met in full.

         

	 	7.5	Bonding: Lessee is required to carry bonding in the amount determined by regulatory authorities for each area to be bonded. Lessee may qualify for self-bonding if the Lessee meets the requirements of C.F.R. Title 30 § 800.23 and any additional requirements in the State or Federal program. Alternatively, Lessee may support its reclamation bonding requirements through third-party bonding facilities.

   

	8.	Production Records: Lessee shall keep accurate records of the sale or shipment of Product from the Properties, and these records shall be available for inspection and copying by Lessor at all reasonable times.

 

	9.	Liens and Notices of Non-Responsibility: Lessor and Lessee agree to keep the Properties at all times free and clear of all liens, charges and encumbrances of any and every nature and description done, made or caused by them, and to pay all indebtedness and liabilities incurred by or for them which may or might become a lien, charge or encumbrance against the Properties before such indebtedness or liability shall become a lien, charge or encumbrance. For clarity, Lessee acknowledges that this does not apply to the current GF Comstock 2, LP debenture.

 

     

     

    

 

	10.	Taxes:
