COMSTOCK MINING INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

FOR THE PERIOD ENDED MARCH 31, 2019 (UNAUDITED)

1. Interim Financial Statements

Basis of Presentation

The interim condensed consolidated financial statements of Comstock Mining Inc. and subsidiaries (“Comstock”, the “Company”, “we”, “our” or “us”) have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In our opinion, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three month period ended March 31, 2019, are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. For further information, refer to the financial statements and footnotes thereto in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

Liquidity and Management Plans

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States and contemplates the Company's continuation as a going concern.

The Company has recurring net losses from operations and an accumulated deficit of $233.9 million at March 31, 2019. For the three month period ended March 31, 2019, the Company incurred a net loss of $1.8 million and used $0.9 million of cash in operations. As of March 31, 2019, the Company had cash and cash equivalents of $0.3 million, current assets of $10.1 million and current liabilities of $3.9 million, resulting in current working capital of $6.2 million.

The Company’s current capital resources include cash and cash equivalents and other net working capital resources, an equity purchase agreement capacity and a loan commitment agreement with $9.5 million in unused capacity after consideration of fees due at the time of borrowing. These capital resources are in addition to the planned asset sales.

In February 2019, the Company filed a new shelf registration statement on Form S-3, for the purchase of up to $50 million of the Company’s securities and also entered into an equity purchase agreement (the "2019 Equity Agreement") with the Murray Family Office ("Murray FO") for the sale of up to $5.0 million in shares of the Company's common stock from time to time, at the Company’s option, subject to certain restrictions and at a 10% discount to a volume weighted average price.

On February 25, 2019, the Company entered into an agreement to sell the Industrial Park and water rights, for a cash purchase price of $7.2 million and to sell its rights in the membership interests of Downtown Silver Springs, LLC (“DTSS”) for $2.5 million. After closing, the Company will retain a right to receive 3% of the amount of the carried interest that the general partner of the fund that purchased such property is due to receive after all costs, expenses, investor hurdles and returns are deducted from the gross proceeds arising from any gain with respect to such property by the buyer.

Through May 3, 2019, the Company has received $2.4 million in non-refundable deposits relating to a Membership Purchase Agreement (the "Tonogold Agreement") with Tonogold Resources Inc. ("Tonogold"). The Company used $1.6 million of the proceeds to reduce its indebtedness under the 11% Senior Secured Debenture (the "Debenture").

On April 3, 2018, the Company received a $2.0 million cash payment relating to an option agreement (the “Option Agreement”) with Tonogold. The Company used $1.4 million of the proceeds to reduce its indebtedness under the 11% Debenture. In addition, the Option Agreement requires Tonogold to reimburse the Company for certain expenditures associated with the Lucerne Mine Project. The Company recognized approximately $0.2 million in expense reimbursements during both of the three months ended March 31, 2019, and 2018, respectively.

8

Future operating expenditures above management’s expectations, including exploration and mine development expenditures in excess of amounts to be raised from the issuance of equity under the 2019 Equity Agreement, declines in the market value of properties held for sale, or declines in the share price of the Company's common stock would adversely affect the Company’s results of operations, financial condition and cash flows. If the Company was unable to obtain any necessary additional funds, this could have an immediate material adverse effect on liquidity and could raise substantial doubt about the Company’s ability to continue as a going concern. In such case, the Company could be required to limit or discontinue certain business plans, activities or operations, reduce or delay certain capital expenditures or sell certain assets or businesses. There can be no assurance that the Company would be able to take any such actions on favorable terms, in a timely manner or at all.

While the Company has been successful in the past in obtaining the necessary capital to support its operations, including registered equity financings from its existing shelf registration statement, borrowings, or other means, there is no assurance that the Company will be able to obtain additional equity capital or other financing, if needed. However, the Company believes it will have sufficient funds to sustain its operations during the next 12 months from the date the financial statements were issued as a result of the funding sources detailed above.

Use of Estimates

In preparing financial statements in conformity with generally accepted accounting principles, we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenditures during the reported periods. Actual results could differ materially from those estimates. Estimates may include those pertaining to estimated useful lives and valuation of properties, plant, and equipment, assets held for sale, mineral rights, deferred tax assets, derivative assets and liabilities, reclamation liabilities, stock-based compensation and payments, and contingent liabilities.

Comprehensive Loss

The only component of comprehensive loss for the three-month periods ended March 31, 2019, and 2018, was our net loss.

Income Taxes

We recognize deferred tax assets and liabilities based on differences between the consolidated financial statement carrying amounts and tax basis of certain recorded assets and liabilities and for tax loss carryforwards. Realization of deferred tax assets is dependent upon our ability to generate sufficient future taxable earnings. Where it is more likely than not that the deferred tax asset will not be realized, we have provided a full valuation allowance. The Company has provided a full valuation allowance at March 31, 2019, and December 31, 2018, for its net deferred tax assets because we cannot conclude it is more likely than not that they will be realized.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Topic 842 affects any entity that enters into a lease, with some specified scope exceptions. For public business entities, the amendments in this update are effective for financial statements issued for annual periods beginning after December 15, 2018, and interim periods within those annual periods. The Company adopted this guidance on January 1, 2019, with no material impact on the Company’s condensed consolidated financial statements.

2. Assets Held For Sale

The Company has committed to a plan to sell certain land, buildings, and water rights ("the Non-mining assets"). In January 2019, the Company committed to a plan to sell certain mining properties. As of March 31, 2019, and December 31, 2018, the Company has assets with a net book value of $6.9 million and $5.4 million, respectively, which met the criteria to be classified as assets held for sale. Those criteria specify that the asset must be available for immediate sale in its present condition (subject only to terms that are usual and customary for sales of such assets), the sale of the asset must be probable, and its transfer expected to qualify for recognition as a completed sale generally within one year. Proceeds from the sale of these assets are required to be used to satisfy obligations due under the terms of the debenture with GF Comstock 2 LP as described in Note 7.

Debt Obligations

GF Comstock 2 LP

On January 13, 2017, the Company issued an 11% Senior Secured Debenture (the "Debenture") to GF Comstock 2 LP due 2021 in an aggregate principal amount of $10,723,000. The Debenture is collateralized by (1) substantially all of the assets of the Company, and (2) a pledge of 100% of the equity of the subsidiaries of Comstock Mining Inc. The use of proceeds included refinancing substantially all of the Company’s current obligations, except the amount due to Caterpillar Finance. The Debenture was issued at a discount of approximately $568,000 and the Company incurred issuance costs of approximately $528,000. The Debenture required an additional "Make Whole" obligation totaling approximately $688,000 if paid any time prior to or at maturity. At March 31, 2019, the remaining balance on the Make Whole obligation was $418,765. Total principal on the Debenture is due on January 13, 2021. The Debenture requires acceleration of payment of accrued interest, principal, and the related Make Whole obligation from all net proceeds received upon the sale of any of the assets of the Company.

Interest is payable semi-annually. For the first two years, interest was payable, at the option of the Company, either in cash or in the form of additional Debentures (or a combination thereof). For the third and fourth years, interest is payable only in cash. In 2018, the Company elected to make the semi-annual interest payments in the form of additional Debentures (Payment in Kind).

Hard Rock Nevada Inc., an employee owned entity, and another related party who is a significant shareholder of the Company, participated in this financing.

Loan Commitment

In 2017, and amended in February 2019, the Company entered into a loan commitment agreement that provides up to $10 million in borrowing capacity and expires in 2021 with an 11% interest rate. Principal amounts borrowed under this agreement are not due until 2021. Interest on any borrowings will be payable in cash and/or in the form of additional indebtedness under the agreement, at the Company’s option. No amounts have been borrowed under this agreement and the Company has $9.5 million (after consideration of fees due at the time of borrowing) of available borrowing capacity.

9. Leases

The Company has an operating lease for a property located adjacent to the Gold Hill Hotel, which is primarily used as a room rental. The lease commenced in 2018, and ends in 2028. The monthly rent is $750 at commencement with automatic annual increases of $25 per month every November, beginning in 2020. The operating lease is sub-leased to the Gold Hill Hotel and not separately valued within the lease of the Gold Hill Hotel. As the operating lease does not provide an implicit rate, we use the Company's incremental borrowing rate at the time of the commencement of the lease in determining the present value of the lease payments. As of the commencement of the lease in 2018, the rate was 11%.

For the three month period ended March 31, 2019, the operating lease expense was $2,250, consisting of a fixed operating lease component. The operating lease has a remaining term of 9.5 years as of March 31, 2019.

Supplemental cash flow information related to the Company's operating lease for the three month period ended March 31, 2019, are as follows:

Cash paid for amounts included in the measurement of lease liabilities	$	2,250

10. Commitments and Contingencies

The Company has minimum royalty obligations with certain of its mineral properties and leases. For most of the mineral properties and leases, the Company is subject to a range of royalty obligations once production commences. These royalties range from 0.5% to 5% of net smelter revenues (NSR) from minerals produced on the properties, with the majority being under 3%. Some of the factors that will influence the amount of the royalties include ounces extracted and the price of gold.

The Company’s mining and exploration activities are subject to various laws and regulations governing the protection of the environment. These laws and regulations are continually changing and are generally becoming more restrictive. The Company believes its operations are in compliance with applicable laws and regulations in all material respects. The Company has made, and expects to make in the future, expenditures to comply with such laws and regulations, but cannot predict the full amount of such future expenditures.

On January 31, 2014, the Comstock Residents Association (the “CRA”) and two of its members filed a civil action in the Third Judicial District Court of the State of Nevada in and for Lyon County (the “District Court”) against the Lyon County Board of Commissioners (the “Commissioners”) and the Company, asking the District Court to reverse the Commissioners’ decision to grant an application for master plan amendment and zone change submitted and approved by the Commissioners on January 2, 2014 (the “Application”).

Prior to the approval of the Application, the master plan designation and zoning precluded mining on certain property of the Company in the area of Silver City, Lyon County. In April 2015, the District Court ruled in favor of the Company and the Commissioners. The written Order Denying Petition for Judicial Review was filed and mailed to all parties on June 15, 2015. On July 14, 2015, the CRA and one individual (together “Appellants”) filed a Notice of Appeal of the Court Order, appealing the decision to the Nevada Supreme Court. On December 9, 2015, Appellants filed their Opening Brief in the Nevada Supreme Court, generally repeating the arguments that were made at the District Court. On January 15, 2016, the Company and the Commissioners jointly filed an Answering Brief. Briefing in the Nevada Supreme Court was completed with the Appellants’ filing of a Reply Brief on March 3, 2016. An oral argument before a three-judge panel of the Nevada Supreme Court took place on September 14, 2016.

On December 2, 2016, the Nevada Supreme Court entered an order affirming all three of the District Court’s decisions associated with 1) the Commissioners’ discretion and authority for changing master plans and zoning, 2) their compliance with Nevada’s Open Meeting Law and 3) their compliance with Nevada statutory provisions. Specifically, the Supreme Court affirmed the District Court’s conclusions that Lyon County did not abuse its discretion and that it acted with substantial evidence in support of their decision, that the County did not violate Nevada’s Open Meeting Law and that the County did not violate statutory provisions regarding master plans.

The Supreme Court reversed the District Court’s dismissal of CRA’s claim of a due process violation, concluding that this claim should not have been dismissed and that further proceedings are necessary in the District Court on this single claim.  The Company and the Commissioners filed a motion for summary judgment with the District Court based on the evidence in the record and the District Court held a hearing on December 11, 2017. The District Court concluded that the Supreme Court's reversal of CRA's due process claim required that CRA be afforded the opportunity to conduct discovery. Therefore, the District Court has allowed a limited time for CRA to conduct discovery on its due process claim. The Company responded to the CRA discovery request on February 20, 2018 and the District Court held a hearing on April 23, 2018. Additional discovery was allowed by the District Court. On May 14, 2019, the Court held a hearing on CRA's due process claim and issued its ruling from the bench.  The Court concluded that CRA, having been afforded the opportunity to conduct discovery, was unable to

13

meet its burden to establish by a preponderance of the evidence that Lyon County had denied CRA of its due process rights.  The Court, therefore, denied CRA's claim for violations of due process.  A written order confirming the Court's ruling is expected to be issued forthwith.

On July 12, 2018, Precious Royalties LLC (“Precious”) filed a complaint against the Company in the First Judicial District Court of the State of Nevada, in Storey County, against the Company, alleging that the Company failed to properly pay Precious a net smelter return royalty in accordance with a settlement agreement dated September 24, 2012, and seeking $510,000 in damages. On November 16, 2018, the Company filed a Motion for a More Definite Statement on the basis that the complaint is too vague to allow a responsive pleading. On May 16, 2019, the Court granted the Company’s Motion, which required Precious to revise and re-file its complaint in order to proceed with the action. Precious re-filed the complaint on June 5, 2019. The Company believes that the claims made in this complaint are without merit and the Company intends to vigorously defend this litigation.

From time to time, we are involved in lawsuits, claims, investigations and proceedings that arise in the ordinary course of business. There are no other matters pending that we expect to have a material adverse impact on our business, results of operations, financial condition or cash flows.

11. Stockholders’ Equity

Equity Offering Program

In February 2019, the Company entered into an equity sales agreement (the "2019 Equity Agreement") with Murray FO for the sale of up to $5.0 million in shares of the Company's common stock from time to time, at the Company’s option, subject to certain volume and pricing restrictions. Shares purchased under the 2019 Equity Agreement will be purchased at a 10% discount to the volume weighted average sales price of such shares prior to the Company initiating sales. The shares will be sold pursuant to the Company’s shelf registration statement on Form S-3, filed on February 26, 2019, for the purchase of up to $50 million of the Company’s securities.

Effective August 2018, the Company entered into an equity sales agreement (the "2018 Sales Agreement") with Leviston Resources for the sale of up to $2.25 million in shares of the Company's common stock from time to time, at the Company's option. As of March 31, 2019, the Company has issued shares with an aggregate sales price of $1.7 million under the 2018 Sales Agreement. Final proceeds from the 2018 Sales Agreement were received in February 2019 and the 2018 Sales Agreement was terminated.

Effective April 2017, the Company entered into an equity sales agreement (the "2017 Sales Agreement") with Leviston for the purchase of up to $7.25 million in shares of the Company's common stock from time to time, at the Company's option. Effective August 2018, the Company and Leviston terminated the 2017 Sales Agreement and made no further sales pursuant to that program. At the time of termination, the Company had issued shares with an aggregate purchase price of $5.3 million.

Effective June 2016, the Company entered into an at-the-market offering sales agreement program (the “ATM Agreement”) wherein the Company could offer and sell, from time to time at its sole discretion, shares of its common stock, having an aggregate offering price of up to $5.0 million. Final proceeds from the ATM Agreement were received in January 2018, and the ATM Agreement was terminated. The Company paid the sales agent a commission of 2.5% of the gross proceeds.

During the year ended December 31, 2018, the Company issued Leviston 877,233 common shares valued at $0.2 million for issuance fees under the 2017 Sales Agreement and the 2018 Sales Agreement.

In January 2018, the Company issued 1,475,410 shares of restricted stock as initial payment to acquire 25% of the total membership interests of Pelen, LLC (Note 15).

12. Net Loss Per Common Share

Basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted loss per share reflects the potential dilution that could occur if stock options were exercised.

The following is a reconciliation of the numerator and denominator used in the basic and diluted computation of net loss per share: 

	Three Months Ended   March 31,
	2019			2018
Numerator:
Net loss	$	(1,835,065	)	$	(2,484,903	)

13. Fair Value Measurements

Assets and Liabilities Measured at Fair Value on a Recurring Basis

During the three months endedMarch 31, 2019 and the year ended December 31, 2018, there were no transfers of assets and liabilities between Level 1, Level 2, or Level 3.

15

The following table presents our liabilities at March 31, 2019 which are measured at fair value on a recurring basis:

			Fair Value Measurements at
			March 31, 2019
	Total		Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Liabilities:
Accrued make-whole for Pelen LLC (Note 15)	$	—	$	—	$	—	$	—
Total Liabilities	$	—	$	—	$	—	$	—

The following table presents our liabilities at December 31, 2018 which are measured at fair value on a recurring basis:

			Fair Value Measurements at
			December 31, 2018
	Total		Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Liabilities:
Accrued make-whole for Pelen LLC (Note 15)	$	135,162	$	—	$	135,162	$	—
Total Liabilities	$	135,162	$	—	$	135,162	$	—

Following is a description of the valuation methodologies used for the Company's financial instruments measured at fair value on a recurring basis as well as the general classification of such instruments pursuant to the valuation hierarchy.

Accrued make-whole for Pelen LLC - The accrued make-whole is valued based on the difference between the valuation of the outstanding shares held by the seller of the membership interests at the Company's closing stock price of $0.21 on March 31, 2019, and $0.13 on December 31, 2018, as compared to the remaining aggregate proceeds due. Because the inputs are all observable market-based inputs, this instrument is classified within Level 2 of the valuation hierarchy.

The carrying amount of cash and cash equivalents and trade payables approximates fair value because of the short-term maturity of these financial instruments. At March 31, 2019, and December 31, 2018, the fair value of long-term debt approximated $8.0 million and $8.9 million, respectively, as determined by borrowing rates estimated to be available to the Company for debt with similar terms and conditions. The fair value of assets and liabilities whose carrying value approximates fair value is determined using Level 2 inputs, with the exception of cash and cash equivalents (Level 1).

15. Acquisition Agreements

Pelen, LLC

In January 2018, the Company issued 1,475,410 shares of restricted common stock as initial payment to acquire 25% of the total membership interests of Pelen, LLC. The purchase of the membership interests will close once the seller of the membership interests has received total cash proceeds of at least $0.6 million either through sale of the restricted common stock received or through additional cash payments made by the Company. If all of the shares of restricted common stock have been sold by the seller of the membership interests and the aggregate proceeds received are less than $0.6 million, then the Company is required to pay the shortfall in either additional shares of the Company’s common stock or cash, at the Company’s election. In November 2018, the Company issued 1,758,181 shares of restricted common stock as additional shares based on the shortfall on the aggregate proceeds for the initial shares. In December 2018, the agreement was amended to have a "Cut-Off" date of December 31, 2019, for closing the transaction and any unsold shares will be returned to the Company, with the Company required to make up any shortfall in cash. As of March 31, 2019, the purchase has not closed and the Company has not received legal ownership of the membership interests. As of March 31, 2019, the Company has no make-whole liability recorded as the value of the shares issued based on the March 31, 2019 share price exceeds the value of the remaining purchase price. The Company has recorded a make-whole liability of $0.1 million at December 31, 2018, representing the value of the shortfall based on the actual sales of shares and the share price as of December 31, 2018. This amount is recorded within accrued expenses in the condensed consolidated balance sheet.

Downtown Silver Springs, LLC

The Company entered into an agreement for the purchase of 100% of the membership interests DTSS on May 30, 2018, as amended. DTSS holds a contract for the purchase of approximately 160 acres of centrally located land in Silver Springs, Nevada. DTSS has no other assets, operations or employees.

The Company’s CEO advanced $25,000 to the equity holders of DTSS in 2017, from his own funds. In the second quarter of 2018, the Company was presented with an opportunity to acquire DTSS and, and after disclosure of such advance, the Board of Directors unanimously approved such acquisition.  In connection with the closing of the acquisition of DTSS in August 2018, the equity holders of DTSS repaid $25,000 to the Company’s CEO, without interest or profit.

The agreement to purchase the land allows the holder of the option to purchase the land for approximately $3.2 million, plus 4% interest less deposits made through May 31, 2019 totaling $1.8 million. The current amendment requires DTSS to close on the land purchase by August 30, 2019, with non-refundable deposits of $0.4 million due on June 24, 2019 and $0.3 million due on July 29, 2019 with a remaining balance due of approximately $1.0 million excluding interest.

On February 25, 2019 as amended on June 18, 2019, the Company entered into an agreement to sell its rights in the membership interests of Downtown Silver Springs, LLC (“DTSS”) for $2.5 million plus any additional deposits made by the Company and 3% of the carried interest. The purchaser of DTSS, as well as the Company, under that agreement is allowed to negotiate extensions and different terms with the seller. After closing of the sale of the option by DTSS, the Company will retain a right to receive 3% of the amount of the carried interest that the general partner of the fund that purchased the option is due to receive after all costs, expenses, investor hurdles and returns are deducted from the gross proceeds arising from any gain with respect to such option purchased by the buyer.

The DTSS acquisition was accounted for as an asset acquisition as it was determined that the operations of DTSS do not meet the definition of a business. The Company paid total consideration of $2.1 million, as of March 31, 2019 which consists of (1) $1.6 million cash deposits that will reduce the final purchase price of the land parcel, and (2) $0.5 million cash payments to the former membership interest holders of DTSS ($0.4 million of which has been paid). As the options expire on August 31, 2019, the total consideration has been recorded in prepaid expenses.

As of March 31, 2019, the Company has made non-refundable deposits of $1.6 million which are recorded in prepaid expenses and other current assets in the condensed consolidated balance sheet.

16. Agreements with Tonogold

Membership Interest Purchase Agreement

On January 24, 2019, the “Company entered into an agreement with Tonogold (the “Tonogold Agreement”). Under the terms of the Tonogold Agreement, the Company will sell Tonogold its interests in Comstock Mining LLC, a wholly-owned subsidiary of Comstock (“CML”) whose sole assets are the Lucerne Mine properties and related permits. Upon closing, the Tonogold Agreement would replace the October 2017 Option Agreement (the "Option Agreement").

The purchase price for CML is $15 million, plus Tonogold will also guarantee the Company’s financial responsibility for its membership interest in Northern Comstock LLC, who owns and leases certain mineral properties in the Lucerne area, and assume certain reclamation liabilities. The Company also retains a 1.5% net smelter return royalty on the Lucerne properties.

Amendments to Tonogold Agreement

On April 30, 2019, the Company and Tonogold entered into the Purchase Agreement Amendment ("First Amendment)"), which allows Tonogold the option to extend the closing until August 30, 2019, upon the payment of three additional $1 million non-refundable deposits and other considerations. In addition, the First Amendment requires Tonogold to reimburse the Company the monthly interest expense on the Senior Secured Debenture (GF Comstock 2) beginning on June 1, 2019, through the latest possible closing of August 30, 2019.

On May 22, 2019, the Company and Tonogold entered into the Second Purchase Agreement Amendment ("Second Amendment"), which allowed Tonogold to forgo funding the remaining $0.7 million in cash payments due in May, 2019, as required in the First Amendment. The total cash consideration for the Tonogold Agreement remains at $11.5 million in cash. The Second Amendment required that Tonogold issue the Company $3.5 million in convertible preferred shares ("Preferred Shares"), subject to certain pricing conditions and restrictions. Tonogold also issued an additional $0.4 million in Preferred Shares as a commitment fee. The Preferred Shares were issued on June 7, 2019.

The Preferred Shares convert to common shares of Tonogold in two equal tranches after closing the transaction. The first tranche converts upon the four month anniversary of the closing and the second tranche at the twelve month anniversary. The conversion price is the lowest of Tonogold’s (1) 20-day volume weighted closing price prior to conversion, (2) most recent private placement, or (3) initial public offering price. If the closing does not occur within the amended timelines, the stock is automatically convertible at 85% of the then current volume weighted average price.

As of June 7, 2019, Tonogold has paid the Company $2.35 million in non-refundable cash deposits and $3.5 million in non-refundable Preferred Shares associated with the $15 million purchase price with a remaining balance due of $9.15 million.

Option Agreements under Tonogold Agreement

The Company and Tonogold also agreed that commencing upon the closing of the sale of CML, it will enter into a new Option Agreement to lease its permitted American Flat mining property, plant and equipment to Tonogold for crushing, leaching and processing material from the Lucerne mine. Under this new Option Agreement, Tonogold will be required to reimburse the Company for an additional $1.1 million per year to maintain the processing facility lease option. If such option is exercised, Tonogold will then pay the Company a rental fee of $1 million per year plus $1 per processed ton, in addition to all the costs of operating and maintaining the facility, up to and until the first $15 million in rental fees are paid, and then stepping down to $1 million per year and $0.50 per processed ton for the next $10 million paid to the Company.

The Company has also agreed, upon the closing of the sale of CML, to enter into a ten-year mineral lease for additional mineral properties in Storey County, Nevada, granting Tonogold the right to explore, develop and mine these properties. Tonogold will assume approximately $100,000 in annual costs for these properties and will assume work commitments totaling more than $200,000 in 2019. The Company will retain a 3% net smelter return royalty on these additional leased properties, which will be reduced to 1.5% one year after the commencement of mining operations. The lease is renewable for an additional ten-year term.

Existing Option Agreement

On October 3, 2017, the Company entered into the Option Agreement with Tonogold. Under the terms of the Option Agreement, Tonogold has the right to participate in certain activities, including but not limited to, engineering, development, drilling and test-work, towards completing an economic feasibility assessment on certain properties within the Company’s Lucerne resource area (the “Lucerne Property”). The Option Agreement remains in effect until the Tonogold Agreement closes.

19

Under the terms of the Option Agreement, Tonogold can earn a 51% interest in CML, which owns the Lucerne Property by meeting certain requirements and financial milestones. These requirements and milestones include: (1) making capital expenditures on the Lucerne Property and related expense reimbursements to the Company of $20 million no later than 42-months following the Commencement Date of April 3, 2018, and (2) making option payments totaling $2.2 million to the Company. Tonogold made a $0.2 million option payment on October 3, 2017, and a second and final option payment of $2.0 million on April 3, 2018. The option payments were both recorded within stockholders' equity as they relate to Tonogold’s right to earn-in to a 51% interest in CML. The Company has recognized approximately $0.2 million and $0.2 million in expense reimbursements for the three months ended March 31, 2019, and 2018, respectively.

On April 9, 2019, the Company received $0.2 million from Tonogold for routine reimbursement for monthly expenses and for the remaining balance due on the March 2019 non-refundable deposit.

The Company is a Nevada-based, gold and silver mining exploration, development and production company with extensive, contiguous property in the historic Comstock and Silver City mining districts (collectively, the “Comstock District”) and additional mining, commercial and industrial properties located in Storey and Lyon Counties, Nevada. The Comstock District is located within the western portion of the Basin and Range Province of Nevada, near Reno and Carson City. The Company began acquiring properties and developing projects in the Comstock District in 2003. Since then, the Company has consolidated a substantial portion of the historic Comstock District, secured permits, built an infrastructure and brought exploration projects into production.

The Company and its subsidiaries now own or control approximately 9,358 acres of mining claims and parcels in the broader Comstock District and surrounding area. The acreage includes approximately 2,396 acres of patented claims and surface parcels (private lands) and approximately 6,962 acres of unpatented mining claims (public lands), which the Bureau of Land Management (“BLM”) administers. The Company's headquarters is on American Flat road, immediately north of the Lucerne resource area and just south of Virginia City, Nevada

Because of the Comstock District’s historical significance, the geology is well known and has been extensively studied by the Company, our advisors and many independent researchers. We have expanded our understanding of the geology through vigorous surface mapping and drill hole logging. The volume of geologic data is immense, particularly in the Lucerne and Dayton resource areas. We have amassed a large library of historic data and detailed surface mapping of Comstock District properties and continue to obtain historic information from private and public sources. We integrate this data with information obtained from our recent mining operations, to target geological prospective exploration areas and plan exploratory drilling programs, including expanded surface and underground drilling.

The Company continues evaluating and acquiring properties, expanding its footprint and evaluating all of our existing and prospective opportunities for further exploration, development and mining. The near-term goal of our business plan is to maximize intrinsic stockholder value realized, per share, by continuing to acquire and develop mineralized and potentially mineralized properties, exploring, developing and validating qualified resources (measured, indicated and inferred) and reserves (proven and probable) that enable the commercial development of our properties through extended, long-lived mine plans that are economically feasible and socially responsible, including mine plans for both the Dayton and Lucerne resource areas, with both surface and underground development opportunities.

Our Dayton resource area and the adjacent Spring Valley exploration targets are located in Lyon County, Nevada, approximately six miles south of Virginia City. Access to the properties is by State Routes 341 and 342, both paved roads.

Our Lucerne resource area is located in Storey County, Nevada, approximately three miles south of Virginia City and 30 miles southeast of Reno. The Lucerne resource area was host to the Company’s most-recent test mining operations from 2012 through 2015. The processing facility is in American Flat, approximately three quarters of a mile west of Lucerne.

The Company achieved initial production and its first pour of gold and silver on September 29, 2012. The Company ceased mining in 2015 and concluded processing in 2016. From 2012, through 2016, the Company mined and processed approximately 2.6 million tons of mineralized material, and produced 59,515 ounces of gold and 735,252 ounces of silver.

Current Projects

The Company has identified many exploration targets on its land holdings in the Comstock District, but has focused, to date, on the Dayton resource area and the Lucerne resource area (including surface and underground exploration). We are working to develop comprehensive exploration plans for the remaining areas, which include the Spring Valley group, Occidental group, and Gold Hill group of exploration targets. Exploration activities will proceed subsequent to and in some cases concurrent with the ongoing exploration and development of the Dayton and Lucerne resource areas.

 The Dayton resource area is south of Virginia City in Lyon County, Nevada. It generally includes the historic Dayton, Kossuth and Alhambra patents, including the old Dayton Consolidated mine workings, south to where the Kossuth patent crosses State Route 341. The historic Dayton mine was the last meaningful underground mining operation in the Comstock District, before being closed after the War Production Board published Limitation Order L-208, 7 F. R. 7992 on October 8, 1942, that closed down all gold mining operations in the United States and its territories. The Dayton resource area ranks as one of the Company’s top exploration and potential mine development targets. In January 2014, the Lyon County Board of Commissioners approved strategic master plan and zoning changes on the Dayton, Kossuth and Alhambra mining patents and other properties located in the Dayton resource area, enabling a more practical, comprehensive feasibility study for mining. Geological studies and development planning are currently underway utilizing data from extensive metallurgical testing and assessment during 2017, 30,818 feet of additional drilling completed in 2015, geophysical analysis and interpretation completed in 2013, and extensive geological data from pre-2013, drill programs.

The Spring Valley group of exploration targets lies adjacent to the Dayton resource area at the southern end of the Comstock District, where the mineralized structures, trending to the south from the Dayton resource area, lie mostly concealed beneath a veneer of sediment gravels. Spring Valley includes the southern portion of the Kossuth patented claim and the Dondero, Daney and New Daney claims, as well as the Company’s placer mining claims in Spring Valley and Gold Canyon.

The Lucerne resource area has been the primary focus of the Company’s exploration and development efforts since 2007. It includes the previously mined Billie the Kid, Hartford and Lucerne mining patents, and extends east and northeasterly to the area of the historic Woodville (southern-most of the historic Comstock bonanzas), Succor and Lager Beer patents and north to the historic Justice and Keystone mines. The Lucerne resource area is approximately one mile along strike, with explored widths from 600 to 1,800 feet, representing less than three percent of the land holdings controlled by the Company. The Lucerne is the site of our previous mining activities and ongoing exploration program, and the Company holds the key mining permits required to resume surface or underground mining of this area.

Our Lucerne exploration activities included open pit gold and silver test mining from 2004, through 2006, and from late 2012 through 2015. As defined by the Securities Exchange Commission (“SEC”) Industry Guide 7, we have not yet established any proven or probable reserves at our Lucerne mine.

On January 24, 2019, the “Company entered into an agreement with Tonogold (the “Tonogold Agreement”). Under the terms of the Tonogold Agreement, the Company will sell Tonogold its interests in Comstock Mining LLC, a wholly-owned subsidiary of Comstock (“CML”) whose sole assets are the Lucerne Mine properties and related permits. Upon closing, the Company and Tonogold will terminate the Option Agreement (the “Option Agreement”), dated October 3, 2017.

The purchase price for CML is $15 million, plus Tonogold will also guarantee the Company’s financial responsibility for its membership interest in Northern Comstock LLC, who leases certain mineral properties in the Lucerne area, and assume certain reclamation liabilities. The Company also retains a 1.5% net smelter return royalty on the Lucerne properties.

The Tonogold Agreement requires that Tonogold guarantee the Company's financial responsibility for its membership interests in Northern Comstock LLC ("Northern Comstock"), relieving$8 million in future lease and reclamation obligations.

Tonogold has paid the Company $2.4 million in non-refundable cash deposits, as of May 3, 2019, of the total $11.5 million of the cash component of the purchase price. The remaining $3.5 million, in the form of convertible preferred shares of Tonogold, was received on June 7, 2019.

The Company and Tonogold also agreed that commencing upon the closing of the sale of CML, it will enter into a new Option Agreement to lease its permitted American Flat mining property, plant and equipment to Tonogold for crushing, leaching and processing material from the Lucerne mine. Under this new Option Agreement, Tonogold will be required to reimburse the Company for an additional $1.1 million per year to maintain the processing facility lease option. If such option is exercised, Tonogold will then pay the Company a rental fee of $1 million per year plus $1 per processed ton, in addition to all

23

the costs of operating and maintaining the facility, up to and until the first $15 million in rental fees are paid, and then stepping down to $1 million per year and $0.50 per processed ton for the next $10 million paid to the Company.

The Company has also agreed, upon the closing of the sale of CML, to enter into a ten-year mineral lease for additional mineral properties in Storey County, Nevada, granting Tonogold the right to explore, develop and mine these properties. Tonogold will assume approximately $100,000 in annual costs for these properties and will assume work commitments totaling more than $200,000 in 2019. The Company will retain a 3% net smelter return royalty on these additional leased properties, which will be reduced to 1.5% one year after the commencement of mining operations. The lease is renewable for an additional ten-year term.

The Tonogold Agreement would replace the October 2017 Option Agreement between the Company and Tonogold. The October 2017 Option Agreement will remain in place until the Tonogold Agreement closes.

On April 30, 2019, the Company and Tonogold entered into the Purchase Agreement Amendment ("Amendment)"), which allows Tonogold the option to extend the closing until August 30, 2019, upon the payment of three additional $1 million non-refundable deposits and other considerations. In addition, the Amendment requires Tonogold to reimburse the Company the monthly interest expense on the Senior Secured Debenture (GF Comstock 2) beginning on May 31, 2019, through the latest possible closing of August 30, 2019.

On May 22, 2019, the Company and Tonogold entered into the Second Purchase Agreement Amendment ("Second Amendment"), which allowed Tonogold to forgo funding the remaining $0.7 million in cash payments due in May, 2019, as required in the First Amendment. The total cash consideration for the Tonogold Agreement remains at $11.5 million in cash. The Second Amendment required that Tonogold issue the Company $3.5 million in convertible preferred shares ("Preferred Shares"), subject to certain pricing conditions and restrictions. Tonogold also issued an additional $0.4 million in Preferred Shares as a commitment fee. The Preferred Shares were issued on June 7, 2019.

The Occidental group and Gold Hill group of exploration targets represent longer-term exploration target areas that contain many historic mining operations, including the Overman, Con Imperial, Caledonia, and Yellow Jacket mines. We believe that our consolidation of the Comstock District has provided us with opportunities to utilize the historical information available to identify drilling targets with significant potential.

Exploration & Development

The Company's long-term, district-wide plans contemplate the exploration and development of specific, identified geological target areas across the District, which the Company has grouped into the Lucerne resource area, the Dayton resource areas, and Spring Valley, Occidental, and Gold Hill groups of exploration targets. These exploration targets represent over 7 miles of mineralized strike length, with current and historical grades of gold and silver.

Lucerne Resource Area

In December, 2018, the Company received unanimous approval from the Storey County Board of Commissioners to extend its landmark Special Use Permit (“SUP”) for mining and processing for the Lucerne Mine Project for the maximum allowable, 20-year term, extending the original, 10-year permit until September 2, 2034. This permit represents one of the most significant, progressive and collaborative permit approvals in the Company’s history, and its extension strengthens the foundation for the future growth of the Company and its partner in Lucerne’s development, Tonogold Resources, Inc.

The amendment significantly extends the duration of the permitted and allowable uses for the entire Lucerne Mine Project, including the Lucerne Mine and resource area and the fully permitted American Flat processing area. The permit applies to both surface and underground mining, processing, milling, exploration and development, and other ancillary uses.

As described in the Current Projects section, the Company entered into an agreement to sell the Lucerne properties. Under the terms of the Tonogold Agreement, the Company will sell its interests in the Lucerne properties and related permits.

Dayton Resource Area

The Company plans to advance the Dayton Project to full feasibility, with a production ready mine plan within two years of commencing that work. This work has not yet commenced. The plan includes expanding the current resource at the Dayton resource area and continuing southerly into Spring Valley with incremental expansion programs that include exploration and definition drilling of targets identified by the prior conventional percussion, RC and diamond core drill programs and magnetic, IP and resistivity geophysical surveys (see Figure 4).

The Company has retained the independent mining advisory firm of Behre Dolbear to produce a National Instrument 43-101 (“NI 43-101”) compliant technical report for the Dayton resource area, scheduled for completion in 2019. The reporting scope includes an updated, robust mineral resource estimate, plans for expanding and further developing the mineral resource, and most of the prerequisite data for a subsequent Preliminary Economic Assessment (“PEA”). The PEA is the first major step in determining overall economic feasibility for the Dayton project.

The Company previously estimated a mineral resource for Dayton as part of a broader technical report for the Comstock Mine Project, but this new, Behre Dolbear commissioned technical report represents the first stand-alone NI 43-101 technical report to be published specifically for the Dayton resource area. Since our last Dayton resource estimate, the Company has:

• Increased the Dayton project property position, both mining claims and private land, including more than 350 acres of contiguous private lands suitable for a dedicated mineral processing site;

• Achieved a landmark, Lyon County Master Plan and zoning change that broadened the potential land uses and restored mining as an appropriate use for the historic mining patents;

• Submitted our project estimates for due diligence reviews by SRK Consulting in both Reno and Denver offices;

• Restored several historic Dayton mine portals for safe exploration of the accessible mine workings;

• Completed underground geologic mapping of the accessible mine workings and completed underground sampling;

• Completed significant assaying and other analysis for furthering the geologic interpretation;

• Identified new, broader mineralized zones and structures;

• Drilled 408 shallow holes totaling 30,819 feet, identifying new mineralized structures covered by shallow alluvium;

• Improved, meaningfully, the geologic mapping of the area;

• Expanded trials by Cycladex, a strategic investee, testing their patented, cycladextrin lixiviant, a potential alternative to cyanide heap leaching for our Dayton materials; and

• Commenced trials with Itronics, Inc., using their KAM-Thio metallurgical recovery processes, another potential alternative to cyanide heap leaching for our Dayton materials.

The new information is supporting the development of a completely updated, detailed, three-dimensional model of the Dayton project. The Company’s technical staff is currently compiling a detailed structural interpretation of the Dayton resource area, which will provide the framework for the new resource model. The detailed interpretation is leading to a list of highly prospective drill targets to further define and expand the mineral resource.

27

In-house Dayton engineering and mine planning have resulted in profiling various economic shells with multiple cutoff grade scenarios. Multiple layout plans for the mine and corresponding processing facilities have been conceptually developed and located on lands 100% privately held by the Company, thus simplifying and shortening the critical permitting chain. The new technical report will provide not only a new resource estimate, but also a phased drilling plan for further defining and expanding the resource for sustainable, profitable mining.

Dayton Metallurgy

The Dayton mineralized material has been subjected to metallurgical testing by independent laboratories as well as in the Company’s on-site lab. Column tests were conducted by McClelland Laboratories in 2011 on medium grade and high grade composites from the Dayton Pit area, at 1” and ½” crush sizes for each sample. The gold recovery after 154 days averaged 86.7% for gold and 47.4% for silver. The final report stated that at the end of the test, the curves had flattened, but recovery was still increasing.

In early 2018, the Company’s in-house lab ran column tests on bulk samples from three different locations in the Dayton resource area: Glory Hole mid-grade, Glory Hole high-grade, and Dayton Adit. Two columns were loaded from each bulk sample. The recovery after 74 days averaged 84% for gold and 55% for silver. The metal recovery had not stopped after 74 days, but the daily incremental increases were below the Company’s analytical detection limits.

The Company is working with strategic partners to test alternative, greener technologies for processing the mineralized material from the Dayton resource area. This includes trials by Cycladex, Inc., a strategic investee, in part funded by the National Science Foundation, for extensive testing of their patented, cycladextrin lixiviant, a potential alternative to traditional cyanide heap leaching.

The Company has also begun trials with Itronics, Inc., to test their KAM-Thio metallurgical recovery processes as an alternative to cyanide heap leaching for processing the Dayton mineralized material. Previous trials by Itronics showed promising results for recovering substantially all the residual silver from the Company’s previously leached material. The Company delivered a bulk sample of higher-grade, Dayton mineralized material to Itronics in August. Itronics has begun testing with two clear objectives: first, to model the same process flow sheet that they developed for processing the previously leached material, and second, to test the ability of the KAM-Thio liquid to recover significant percentages of gold as well as silver. A final result from the testing will be a proposed processing flow sheet and screening level economics for use in the preliminary economic assessment of the Dayton resource.

The ongoing testing of alternative technologies underpins the Company’s commitment to responsible development of the Dayton resource. A breakthrough with any of these cleaner technologies could result in higher, faster recoveries with reduced waste, as well as a streamlined permitting process and lower long-term reclamation costs.

Dayton - Spring Valley Group Targets

Spring Valley is south of the Dayton resource area, extending to the south and east of State Route 341. The volcanic host rocks and structural controls of the mineralization defined to date for the Dayton resource area are known to continue south into Spring Valley. Potentially economic gold mineralization has been intercepted in several widely spaced holes drilled during prior Spring Valley drilling programs.

Ground magnetic geophysical surveys identified a linear anomalous corridor, defined by a series of relative magnetic lows. Altered volcanic host rocks have been intercepted by limited drilling and identified several mineralized zones, the global Dayton resource foot print is outlined with reference to the technical report authored by Behre Dolbear in January 2013. The exploration of Spring Valley will include phased drilling programs that will continue southerly from SR 341 to the historic Daney mine site (Figure 5), with a potential strike length of approximately 9,600 feet.

Figure 5 - Dayton and Spring Valley Group Targets

30

The technical staff reviewed historic geologic and geophysical studies and prior drill programs that focused upon the Dayton resource area and extensions south into Spring Valley. The few drill holes that were completed in Spring Valley intercepted altered Miocene volcanic rock known to host the economic mineralization of the Dayton resource. Specific drill holes that encountered highly mineralized zones are highlighted on Figure 4. Collectively, several specific locations were selected and are targeted for future drilling. The Dayton resource area has open ended economic mineralization requiring additional drill holes to delineate the geometry for mine planning. South of the Dayton resource area the limited drilling coupled with the geophysical interpretation indicates the targeted exploration model extends an additional 8,000 feet (length of geophysical magnetic survey) into Spring Valley.

Ground magnetic geophysical surveys identified a linear anomalous corridor, defined by a series of relative magnetic lows. Altered volcanic host rocks have been intercepted by limited drilling and identified several mineralized zones. Selected drill hole intercepts are highlighted (see Figure 4). The mid-level magnetic lows define a zone (up to 500 feet wide) beginning at the Dayton resource and continuing southerly approximately 8,000 feet (length of geophysical magnetic survey) towards the Daney patent. The zone is further defined by the trace of interpreted north/south trending vein swarms depicted on Figure 4. In the Dayton resource area the increased density of the vein swarms with intersecting cross structures has been indicative to host the higher grades and larger volumes of economic mineralization. This scenario is part of the exploration model and has generated a multiple drill target environment.

The Spring Valley exploration program is designed to target areas that have similar magnetic signatures of known economic grade mineralization. The magnetic geophysical survey was further studied and a structural interpretation was developed that illustrated multiple cross cutting structures (colored green) that are oblique to the southerly projected north/south vein trend (colored red), refer to Figure 4. Though rare due to alluvial cover, the outcropping quartz veins and outcropping crosscutting structures had definitive diagnostic magnetic signatures. The interpretation of the structures and veins were derived by connecting these specific magnetic attributes as identified on each 25-meter spaced survey line. Similar structures have been identified in the Dayton resource area and were found to be important components for the development of economic grades of mineralization.

Pelen-Sutro Tunnel Company Acquisition

In January 2018, the Company issued 1,475,410 shares of restricted common stock as initial payment to acquire 25% of the total membership interests of Pelen, LLC. Pelen, LLC is the 100% owner of the historic Sutro Tunnel Company that owns the Town of Sutro, the historic 6-mile Sutro Tunnel, the federal land grants and mining rights spanning 1,000 feet on each side of the 6-mile span, the rights to the tunnel’s water and the patented mining claims and private lands on Gold Hill.

The purchase of the membership interests will close by December 31, 2019, once the seller of the membership interests has received total cash proceeds of at least $585,000 either through sale of the restricted common stock received or through additional cash payments made by the Company. If all of the shares of restricted common stock have been sold by the seller of the membership interests and the aggregate proceeds received are less than $585,000, then the Company is required to pay the shortfall in either additional shares of the Company’s common stock or cash, at the Company’s election.

The Company issued 1,758,181 additional shares in November, 2018.

Non-mining Real Estate

On February 25, 2019, the Company entered into an agreement to sell the Industrial Park and water rights, for a cash purchase price of $7.2 million. After closing, the Company will retain a right to receive 3% of the amount of the carried interest that the general partner of the fund that purchased such party is due to receive after all costs, expenses, investor hurdles and returns are deducted from the gross proceeds arising from any gain with respect to such property by the buyer.

Downtown Silver Springs, LLC, a wholly-owned subsidiary of the Company, holds a contract for the purchase of approximately 160 acres of centrally located land in Silver Springs, Nevada. On February 25, 2019, the Company entered into an agreement to sell its rights under the purchase agreement for $2.5 million, as adjusted, dollar for dollar, for any additional deposits made by the purchaser of the option to the seller of the property, on behalf of DTSS. After closing, the Company will retain a right to receive 3% of the amount of the carried interest that the general partner of the fund that purchased such property is due to receive after all costs, expenses, investor hurdles and returns are deducted from the gross proceeds arising from any gain with respect to such property by the buyer.

31

The Gold Hill Hotel is listed for sale for $1 million. The Gold Hill Hotel has been consistently cash positive over the past two years. The Daney Ranch is listed for sale for $3.9 million.

Outlook

Our annual operating expenses are planned at $3.8 million, with approximately $1.2 million of that amount currently being reimbursed under the existing Tonogold Option Agreement. We anticipate an additional $1 million in annualized savings, or a total of $2.2 million annually, upon closing the Tonogold Agreement, on or before August 31, 2019. This would result in an early extinguishment of the entirety of our approximately $7.9 million outstanding Senior Secured Debenture obligation, eliminating more than $1 million of annualized interest expense.

The Company’s 2019 plans include advancing the commercialization of certain mining and processing technologies that the Company has been collaborated on, with partners such as HTX Technologies Inc., Cycladex Inc. and Itronics, and additional technologies, including Mercury reclamation and recoveries, that present nearer term revenue opportunities, enhance our potential project economic feasibilities and present additional revenue opportunities.

The Company has also commenced collaborating on community development planning activities in Silver City associated with Dayton Mine planning. The Company also plans on updating Dayton’s current resource estimate and commence activities for obtaining the local permits for the Dayton Project in 2019. The Company will also continue exploration activities southerly into Spring Valley with incremental exploration programs that include exploration and definition drilling of targets identified by geophysical surveys, surface mapping, prior drilling and deeper geological interpretations that all lead to publishing an updated, NI 43-101 compliant, mineral resource estimate for the Dayton Project and expanded exploration in Spring Valley in 2019.

Equity Raises

For the three months endedMarch 31, 2019, the Company issued 5,452,000 common shares through the 2018 Sales Agreement with Leviston Resources. Gross proceeds were approximately $0.8 million at an average price per share of $0.15.

The Company ceased processing material from its leach pad in December 2016, resulting in no mining revenues for the three months ended March 31, 2019, and 2018, respectively.

Real estate revenues for the three months ended March 31, 2019 increased $14,748 as compared to the same period ended March 31, 2018.

Real estate operating costs increased slightly for the three months ended March 31, 2019, as compared to the same period ended March 31, 2018.

Costs applicable to mining revenue decreased by $223,511 during the three months ended March 31, 2019, as compared to the same period ended March 31, 2018, as a result of certain assets becoming fully depreciated. These costs consist solely of depreciation expense on temporarily idled mining equipment, processing facilities and heap leach pads.

Exploration and mine development costs increased $16,329 during the three months ended March 31, 2019, as compared to the same period ended March 31, 2018.

Mine claim and costs decreased by $29,277 during the three months ended March 31, 2019, as compared to the same period ended March 31, 2018, as we recognized additional reimbursements of costs on the Tonogold Option Agreement in 2019, as compared to 2018.

Environmental and reclamation costs were essentially flat during the three months ended March 31, 2019, as compared to the same period ended March 31, 2018.

General and administrative expenses decreased by $66,254 during the three months ended March 31, 2019, as compared to the same period ended March 31, 2018. Approximately $51,000 of the decrease is due to a one year abatement of personal property taxes for the fiscal year 2018/19, granted by the State of Nevada in March 2019. The total personal property tax reduction, net of costs, is about $92,000.

33

Interest expenses increased by $77,797, primarily as a result of the additional make-whole and fees expense recognized on the principal pay downs on the Senior Secured Debentures in the first quarter of 2019, offset by a reduction in actual interest expense based on the overall lower debt in 2019 as compared to 2018.

Other income and expense decreased by $408,890, primarily related to the difference in make-whole expense on the Pelen, LLC acquisition between 2018, and 2019, related to the difference in share price.

Net loss was $1.8 million for the three months ended March 31, 2019, as compared to a net loss of $2.5 million for the three months ended March 31, 2018. The $0.7 million improvement in net loss primarily resulted from a reduction in operating expenses of $0.3 million, the decrease in depreciation expense and the reduction in other income and expenses of $0.4 million related to the make-whole expense change forthe Pelen, LLC acquisition.

Liquidity and Capital Resources

The Company had total assets of $28.2 million, total current assets of $10.1 million, current liabilities of $3.9 million and net current assets of $6.2 million, including cash and cash equivalents of $0.3 million at March 31, 2019. The Company’s current capital resources include cash and cash equivalents and other net working capital resources, along with a loan commitment agreement with $10.0 million in unused capacity, before consideration of fees due at the time of borrowing and an equity sales agreement (the "Sales Agreement") with Murray FO, LLC ("Murray"), with aggregate unused capacity of $4.3 million as of June 11, 2019, pursuant to the Company’s shelf registration statement on Form S-3, filed on February 26, 2019. These capital resources are in addition to certain planned non-mining asset sales and proceeds of the transaction contemplated by the Tonogold Agreement, including an additional $350,000 received subsequent to March 31, 2019.

Net cash used in operating activities was $0.9 million for the three months ended March 31, 2019, as compared to net cash used in operating activities of $1.1 million for the three months ended March 31, 2018, a decrease of $0.2 million, resulting from a decrease in costs and cash management.

Net cash provided by investing activities for the three months ended March 31, 2019, was $1.6 million, primarily relating to deposits on the sale of a property. Net cash provided by investing activities for the three months ended March 31, 2018, was $0.03 million, relating to the sale of a property.

Net cash used by financing activities for the three months ended March 31, 2019, was $0.8 million, comprised the pay down of long-term debt of $1.6 million offset by the net proceeds of $0.7 million from the sale common shares. Net cash provided by financing activities for the three months ended March 31, 2018, was $1.0 million, primarily the net proceeds of $1.1 million from the sale common shares.

The Tonogold Agreement is expected to provide $11.5 million in cash to the Company in 2019. When received, the cash will be used to pay-off the Senior Secured Debenture. The Tonogold Agreement also relieves the Company of $8 million in long-term obligations, primarily $7.2 million for the Northern Comstock annual mine claims and $0.8 million other Lucerne-specific reclamation liabilities with Storey County, Nevada and the State of Nevada. The Tonogold Agreement subsidizes an additional $1 million of annual costs (in addition to current reimbursements of approximately $1.2 million per annum, for a total, post-transaction-closing reduction of approximately $2.2 million of operating savings per annum).

On February 25, 2019, the Company entered into agreements to sell one non-mining asset, that is, the 98-acre certified industrial site and related water rights, and to sell the purchase agreement and option on the 160 acres of land, all located in Silver Springs, NV, for a total of $9.75 million plus a residual 3% future share of the profit. The transactions are expected to be finalized in 2019, and the Company expects to record a gain of approximately $5 million.

The Company has recurring net losses from operations and an accumulated deficit of $233.9 million as of March 31, 2019. While the Company has been successful in the past in obtaining the necessary capital to support its operations, including registered equity financings from its existing shelf registration statement, borrowings, or other means, there is no assurance that the Company will be able to obtain additional equity capital or other financing, if needed. However, the Company believes it will have sufficient funds to sustain its operations during the next 12 months from the date the financial statements were issued as a result of the sources of funding detailed above.

The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America which contemplates continuation of the Company as a going concern.

There have been no material changes in the market risks discussed in Item 7A of our Annual Report on Form 10-K.

ITEM 4. CONTROLS AND PROCEDURES.

A.  Disclosure

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, management performed, with the participation of our Principal Executive Officer and our Principal Financial Officer, an evaluation of the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (“Exchange Act”). Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Exchange Act and the SEC’s rules, and that such information is accumulated and communicated to our management, including our Principal Executive Officer and Principal Financial Officer, to allow timely decisions regarding required disclosures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Our Principal Executive Officer and Principal Financial Officer concluded that, as of March 31, 2019, our disclosure controls and procedures were effective.

Design and Evaluation of Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Our management assessed the effectiveness of our internal control over financial reporting as of March 31, 2019. In making this assessment, management used the criteria for effective internal control over financial reporting described in the “Internal Control-Integrated Framework” (2013) set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on the assessment, management concluded that, as of March 31, 2019, our internal control over financial reporting was effective based on those criteria.

B.  Internal Control over Financial Reporting

No change in our internal control over financial reporting, as such term is defined in Exchange Act Rule 13(a)-15, occurred during the fiscal quarter ended March 31, 2019, that materially affected or is reasonably likely to materially affect our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1.Legal Proceedings.

The Company’s mining and exploration activities are subject to various laws and regulations governing the protection of the environment. These laws and regulations are continually changing and are generally becoming more restrictive. The Company believes its operations are in compliance with applicable laws and regulations in all material respects. The Company has made, and expects to make in the future, expenditures to comply with such laws and regulations, but cannot predict the full amount of such future expenditures.

On January 31, 2014, the Comstock Residents Association (the “CRA”) and two of its members filed a civil action in the Third Judicial District Court of the State of Nevada in and for Lyon County (the “District Court”) against the Lyon County Board of Commissioners (the “Commissioners”) and the Company, asking the District Court to reverse the Commissioners’ decision to grant an application for master plan amendment and zone change submitted and approved by the Commissioners on January 2, 2014 (the “Application”).

Prior to the approval of the Application, the master plan designation and zoning precluded mining on certain property of the Company in the area of Silver City, Lyon County. In April 2015, the District Court ruled in favor of the Company and the Commissioners. The written Order Denying Petition for Judicial Review was filed and mailed to all parties on June 15, 2015. On July 14, 2015, the CRA and one individual (together “Appellants”) filed a Notice of Appeal of the Court Order, appealing the decision to the Nevada Supreme Court. On December 9, 2015, Appellants filed their Opening Brief in the Nevada Supreme Court, generally repeating the arguments that were made at the District Court. On January 15, 2016, the Company and the Commissioners jointly filed an Answering Brief. Briefing in the Nevada Supreme Court was completed with the Appellants’ filing of a Reply Brief on March 3, 2016. An oral argument before a three-judge panel of the Nevada Supreme Court took place on September 14, 2016.

On December 2, 2016, the Nevada Supreme Court entered an order affirming all three of the District Court’s decisions associated with 1) the Commissioners’ discretion and authority for changing master plans and zoning, 2) their compliance with Nevada’s Open Meeting Law and 3) their compliance with Nevada statutory provisions. Specifically, the Supreme Court affirmed the District Court’s conclusions that Lyon County did not abuse its discretion and that it acted with substantial evidence in support of their decision, that the County did not violate Nevada’s Open Meeting Law and that the County did not violate statutory provisions regarding master plans.

The Supreme Court reversed the District Court’s dismissal of CRA’s claim of a due process violation, concluding that this claim should not have been dismissed and that further proceedings are necessary in the District Court on this single claim.  The Company and the Commissioners filed a motion for summary judgment with the District Court bases on the evidence in the record and the District Court held a hearing on December 11, 2017. The District Court concluded that the Supreme Court's reversal of CRA's due process claim required that CRA be afforded the opportunity to conduct discovery. Therefore, the District Court has allowed a limited time for CRA to conduct discovery on its due process claim. The Company responded to the CRA discovery request on February 20, 2018 and the District Court held a hearing on April 23, 2018. Additional discovery was allowed by the District Court. On May 14, 2019, the Court held a hearing on CRA's due process claim and issued its ruling from the bench.  The Court concluded that CRA, having been afforded the opportunity to conduct discovery, was unable to meet its burden to establish by a preponderance of the evidence that Lyon County had denied CRA of its due process rights.  The Court, therefore, denied CRA's claim for violations of due process.  A written order confirming the Court's ruling is expected to be issued forthwith.

On July 12, 2018, Precious Royalties LLC (“Precious”) filed a complaint in the First Judicial District Court of the State of Nevada, in Storey County, against the Company, alleging that the Company failed to properly pay Precious a net smelter return royalty in accordance with a settlement agreement dated September 24, 2012, and Precious is seeking $510,000 in damages. On November 16, 2018, the Company filed a Motion for a More Definite Statement on the basis that the complaint is too vague to allow a responsive pleading. On May 16, 2019, the Court granted the Company’s Motion, which required Precious to revise and re-file its complaint in order to proceed with the action. Precious re-filed the complaint on June 5, 2019.

The Company believes that the claims made in this complaint are without merit and the Company intends to vigorously defend this litigation.

From time to time, we are involved in lawsuits, claims, investigations and proceedings that arise in the ordinary course of business. There are no other matters pending that we expect to have a material adverse impact on our business, results of operations, financial condition or cash flows.

Item 5.Other Information.

Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing or Notice of Delisting - Extension

On August 27, 2018, the Company received notice from the NYSE American LLC (“NYSE”) that it was not compliant with the NYSE’s low selling price rule 1003(f)(v) and would have six months to cure such noncompliance. On February 20, 2019, the Company received notification from the NYSE that the Company has been granted an extension to May 31, 2019, to regain compliance with NYSE’s low selling price rule 1003(f)(v). On June 3, 2019, the Company received notice from the NYSE that the Company had resolved the low selling price rule 1003(f)(v).

On May 22, 2019, the Company received a late filing notice from the NYSE because the Company did not file its Quarterly Report on Form 10-Q for the quarter ended March 31, 2019 on a timely basis. NYSE rules provide for an initial six month cure period.

Exhibit 95

The following disclosures are provided pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K, which requires certain disclosures by companies required to file periodic reports under the Securities Exchange Act of 1934, as amended, that operate mines regulated under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”).

Whenever the Federal Mine Safety and Health Administration (“MSHA”) believes that a violation of the Mine Act, any health or safety standard, or any regulation has occurred, it may issue a citation or order which describes the violation and fixes a time within which the operator must abate the violation. In some situations, such as when the MSHA believes that conditions pose a hazard to persons, MSHA may issue an order requiring removal of persons from the area of the mine affected by the condition until the hazards are correction. Whenever MSHA issues a citation or order, it has authority to propose a civil penalty or fine, as a result of the violation.

The table below reflects citations and orders issued by MSHA during the three months ended March 31, 2019.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Interim Financial Statements

Interim Financial Statements

Basis of Presentation

The interim condensed consolidated financial statements of Comstock Mining Inc. and subsidiaries (“Comstock”, the “Company”, “we”, “our” or “us”) have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In our opinion, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three month period ended March 31, 2019, are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. For further information, refer to the financial statements and footnotes thereto in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

Liquidity and Management Plans

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States and contemplates the Company's continuation as a going concern.

The Company has recurring net losses from operations and an accumulated deficit of $233.9 million at March 31, 2019. For the three month period ended March 31, 2019, the Company incurred a net loss of $1.8 million and used $0.9 million of cash in operations. As of March 31, 2019, the Company had cash and cash equivalents of $0.3 million, current assets of $10.1 million and current liabilities of $3.9 million, resulting in current working capital of $6.2 million.

The Company’s current capital resources include cash and cash equivalents and other net working capital resources, an equity purchase agreement capacity and a loan commitment agreement with $9.5 million in unused capacity after consideration of fees due at the time of borrowing. These capital resources are in addition to the planned asset sales.

In February 2019, the Company filed a new shelf registration statement on Form S-3, for the purchase of up to $50 million of the Company’s securities and also entered into an equity purchase agreement (the "2019 Equity Agreement") with the Murray Family Office ("Murray FO") for the sale of up to $5.0 million in shares of the Company's common stock from time to time, at the Company’s option, subject to certain restrictions and at a 10% discount to a volume weighted average price.

On February 25, 2019, the Company entered into an agreement to sell the Industrial Park and water rights, for a cash purchase price of $7.2 million and to sell its rights in the membership interests of Downtown Silver Springs, LLC (“DTSS”) for $2.5 million. After closing, the Company will retain a right to receive 3% of the amount of the carried interest that the general partner of the fund that purchased such property is due to receive after all costs, expenses, investor hurdles and returns are deducted from the gross proceeds arising from any gain with respect to such property by the buyer.

Through May 3, 2019, the Company has received $2.4 million in non-refundable deposits relating to a Membership Purchase Agreement (the "Tonogold Agreement") with Tonogold Resources Inc. ("Tonogold"). The Company used $1.6 million of the proceeds to reduce its indebtedness under the 11% Senior Secured Debenture (the "Debenture").

On April 3, 2018, the Company received a $2.0 million cash payment relating to an option agreement (the “Option Agreement”) with Tonogold. The Company used $1.4 million of the proceeds to reduce its indebtedness under the 11% Debenture. In addition, the Option Agreement requires Tonogold to reimburse the Company for certain expenditures associated with the Lucerne Mine Project. The Company recognized approximately $0.2 million in expense reimbursements during both of the three months ended March 31, 2019, and 2018, respectively.

Future operating expenditures above management’s expectations, including exploration and mine development expenditures in excess of amounts to be raised from the issuance of equity under the 2019 Equity Agreement, declines in the market value of properties held for sale, or declines in the share price of the Company's common stock would adversely affect the Company’s results of operations, financial condition and cash flows. If the Company was unable to obtain any necessary additional funds, this could have an immediate material adverse effect on liquidity and could raise substantial doubt about the Company’s ability to continue as a going concern. In such case, the Company could be required to limit or discontinue certain business plans, activities or operations, reduce or delay certain capital expenditures or sell certain assets or businesses. There can be no assurance that the Company would be able to take any such actions on favorable terms, in a timely manner or at all.

While the Company has been successful in the past in obtaining the necessary capital to support its operations, including registered equity financings from its existing shelf registration statement, borrowings, or other means, there is no assurance that the Company will be able to obtain additional equity capital or other financing, if needed. However, the Company believes it will have sufficient funds to sustain its operations during the next 12 months from the date the financial statements were issued as a result of the funding sources detailed above.

Use of Estimates

In preparing financial statements in conformity with generally accepted accounting principles, we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenditures during the reported periods. Actual results could differ materially from those estimates. Estimates may include those pertaining to estimated useful lives and valuation of properties, plant, and equipment, assets held for sale, mineral rights, deferred tax assets, derivative assets and liabilities, reclamation liabilities, stock-based compensation and payments, and contingent liabilities.

Comprehensive Loss

The only component of comprehensive loss for the three-month periods ended March 31, 2019, and 2018, was our net loss.

Income Taxes

We recognize deferred tax assets and liabilities based on differences between the consolidated financial statement carrying amounts and tax basis of certain recorded assets and liabilities and for tax loss carryforwards. Realization of deferred tax assets is dependent upon our ability to generate sufficient future taxable earnings. Where it is more likely than not that the deferred tax asset will not be realized, we have provided a full valuation allowance. The Company has provided a full valuation allowance at March 31, 2019, and December 31, 2018, for its net deferred tax assets because we cannot conclude it is more likely than not that they will be realized.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Topic 842 affects any entity that enters into a lease, with some specified scope exceptions. For public business entities, the amendments in this update are effective for financial statements issued for annual periods beginning after December 15, 2018, and interim periods within those annual periods. The Company adopted this guidance on January 1, 2019, with no material impact on the Company’s condensed consolidated financial statements.

Assets Held For Sale

The Company has committed to a plan to sell certain land, buildings, and water rights ("the Non-mining assets"). In January 2019, the Company committed to a plan to sell certain mining properties. As of March 31, 2019, and December 31, 2018, the Company has assets with a net book value of $6.9 million and $5.4 million, respectively, which met the criteria to be classified as assets held for sale. Those criteria specify that the asset must be available for immediate sale in its present condition (subject only to terms that are usual and customary for sales of such assets), the sale of the asset must be probable, and its transfer expected to qualify for recognition as a completed sale generally within one year. Proceeds from the sale of these assets are required to be used to satisfy obligations due under the terms of the debenture with GF Comstock 2 LP as described in Note 7.

Debt Obligations

GF Comstock 2 LP

On January 13, 2017, the Company issued an 11% Senior Secured Debenture (the "Debenture") to GF Comstock 2 LP due 2021 in an aggregate principal amount of $10,723,000. The Debenture is collateralized by (1) substantially all of the assets of the Company, and (2) a pledge of 100% of the equity of the subsidiaries of Comstock Mining Inc. The use of proceeds included refinancing substantially all of the Company’s current obligations, except the amount due to Caterpillar Finance. The Debenture was issued at a discount of approximately $568,000 and the Company incurred issuance costs of approximately $528,000. The Debenture required an additional "Make Whole" obligation totaling approximately $688,000 if paid any time prior to or at maturity. At March 31, 2019, the remaining balance on the Make Whole obligation was $418,765. Total principal on the Debenture is due on January 13, 2021. The Debenture requires acceleration of payment of accrued interest, principal, and the related Make Whole obligation from all net proceeds received upon the sale of any of the assets of the Company.

Interest is payable semi-annually. For the first two years, interest was payable, at the option of the Company, either in cash or in the form of additional Debentures (or a combination thereof). For the third and fourth years, interest is payable only in cash. In 2018, the Company elected to make the semi-annual interest payments in the form of additional Debentures (Payment in Kind).

Hard Rock Nevada Inc., an employee owned entity, and another related party who is a significant shareholder of the Company, participated in this financing.

Loan Commitment

In 2017, and amended in February 2019, the Company entered into a loan commitment agreement that provides up to $10 million in borrowing capacity and expires in 2021 with an 11% interest rate. Principal amounts borrowed under this agreement are not due until 2021. Interest on any borrowings will be payable in cash and/or in the form of additional indebtedness under the agreement, at the Company’s option. No amounts have been borrowed under this agreement and the Company has $9.5 million (after consideration of fees due at the time of borrowing) of available borrowing capacity.

Leases [Abstract]

Leases

Leases

The Company has an operating lease for a property located adjacent to the Gold Hill Hotel, which is primarily used as a room rental. The lease commenced in 2018, and ends in 2028. The monthly rent is $750 at commencement with automatic annual increases of $25 per month every November, beginning in 2020. The operating lease is sub-leased to the Gold Hill Hotel and not separately valued within the lease of the Gold Hill Hotel. As the operating lease does not provide an implicit rate, we use the Company's incremental borrowing rate at the time of the commencement of the lease in determining the present value of the lease payments. As of the commencement of the lease in 2018, the rate was 11%.

For the three month period ended March 31, 2019, the operating lease expense was $2,250, consisting of a fixed operating lease component. The operating lease has a remaining term of 9.5 years as of March 31, 2019.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

The Company has minimum royalty obligations with certain of its mineral properties and leases. For most of the mineral properties and leases, the Company is subject to a range of royalty obligations once production commences. These royalties range from 0.5% to 5% of net smelter revenues (NSR) from minerals produced on the properties, with the majority being under 3%. Some of the factors that will influence the amount of the royalties include ounces extracted and the price of gold.

The Company’s mining and exploration activities are subject to various laws and regulations governing the protection of the environment. These laws and regulations are continually changing and are generally becoming more restrictive. The Company believes its operations are in compliance with applicable laws and regulations in all material respects. The Company has made, and expects to make in the future, expenditures to comply with such laws and regulations, but cannot predict the full amount of such future expenditures.

On January 31, 2014, the Comstock Residents Association (the “CRA”) and two of its members filed a civil action in the Third Judicial District Court of the State of Nevada in and for Lyon County (the “District Court”) against the Lyon County Board of Commissioners (the “Commissioners”) and the Company, asking the District Court to reverse the Commissioners’ decision to grant an application for master plan amendment and zone change submitted and approved by the Commissioners on January 2, 2014 (the “Application”).

Prior to the approval of the Application, the master plan designation and zoning precluded mining on certain property of the Company in the area of Silver City, Lyon County. In April 2015, the District Court ruled in favor of the Company and the Commissioners. The written Order Denying Petition for Judicial Review was filed and mailed to all parties on June 15, 2015. On July 14, 2015, the CRA and one individual (together “Appellants”) filed a Notice of Appeal of the Court Order, appealing the decision to the Nevada Supreme Court. On December 9, 2015, Appellants filed their Opening Brief in the Nevada Supreme Court, generally repeating the arguments that were made at the District Court. On January 15, 2016, the Company and the Commissioners jointly filed an Answering Brief. Briefing in the Nevada Supreme Court was completed with the Appellants’ filing of a Reply Brief on March 3, 2016. An oral argument before a three-judge panel of the Nevada Supreme Court took place on September 14, 2016.

On December 2, 2016, the Nevada Supreme Court entered an order affirming all three of the District Court’s decisions associated with 1) the Commissioners’ discretion and authority for changing master plans and zoning, 2) their compliance with Nevada’s Open Meeting Law and 3) their compliance with Nevada statutory provisions. Specifically, the Supreme Court affirmed the District Court’s conclusions that Lyon County did not abuse its discretion and that it acted with substantial evidence in support of their decision, that the County did not violate Nevada’s Open Meeting Law and that the County did not violate statutory provisions regarding master plans.

The Supreme Court reversed the District Court’s dismissal of CRA’s claim of a due process violation, concluding that this claim should not have been dismissed and that further proceedings are necessary in the District Court on this single claim.  The Company and the Commissioners filed a motion for summary judgment with the District Court based on the evidence in the record and the District Court held a hearing on December 11, 2017. The District Court concluded that the Supreme Court's reversal of CRA's due process claim required that CRA be afforded the opportunity to conduct discovery. Therefore, the District Court has allowed a limited time for CRA to conduct discovery on its due process claim. The Company responded to the CRA discovery request on February 20, 2018 and the District Court held a hearing on April 23, 2018. Additional discovery was allowed by the District Court. On May 14, 2019, the Court held a hearing on CRA's due process claim and issued its ruling from the bench.  The Court concluded that CRA, having been afforded the opportunity to conduct discovery, was unable to meet its burden to establish by a preponderance of the evidence that Lyon County had denied CRA of its due process rights.  The Court, therefore, denied CRA's claim for violations of due process.  A written order confirming the Court's ruling is expected to be issued forthwith.

On July 12, 2018, Precious Royalties LLC (“Precious”) filed a complaint against the Company in the First Judicial District Court of the State of Nevada, in Storey County, against the Company, alleging that the Company failed to properly pay Precious a net smelter return royalty in accordance with a settlement agreement dated September 24, 2012, and seeking $510,000 in damages. On November 16, 2018, the Company filed a Motion for a More Definite Statement on the basis that the complaint is too vague to allow a responsive pleading. On May 16, 2019, the Court granted the Company’s Motion, which required Precious to revise and re-file its complaint in order to proceed with the action. Precious re-filed the complaint on June 5, 2019. The Company believes that the claims made in this complaint are without merit and the Company intends to vigorously defend this litigation.

From time to time, we are involved in lawsuits, claims, investigations and proceedings that arise in the ordinary course of business. There are no other matters pending that we expect to have a material adverse impact on our business, results of operations, financial condition or cash flows.

Fair Value Measurements

Assets and Liabilities Measured at Fair Value on a Recurring Basis

During the three months endedMarch 31, 2019 and the year ended December 31, 2018, there were no transfers of assets and liabilities between Level 1, Level 2, or Level 3.

The following table presents our liabilities at March 31, 2019 which are measured at fair value on a recurring basis:

			Fair Value Measurements at
			March 31, 2019

Total Liabilities	$	135,162	$	—	$	135,162	$	—

Following is a description of the valuation methodologies used for the Company's financial instruments measured at fair value on a recurring basis as well as the general classification of such instruments pursuant to the valuation hierarchy.

Accrued make-whole for Pelen LLC - The accrued make-whole is valued based on the difference between the valuation of the outstanding shares held by the seller of the membership interests at the Company's closing stock price of $0.21 on March 31, 2019, and $0.13 on December 31, 2018, as compared to the remaining aggregate proceeds due. Because the inputs are all observable market-based inputs, this instrument is classified within Level 2 of the valuation hierarchy.

The carrying amount of cash and cash equivalents and trade payables approximates fair value because of the short-term maturity of these financial instruments. At March 31, 2019, and December 31, 2018, the fair value of long-term debt approximated $8.0 million and $8.9 million, respectively, as determined by borrowing rates estimated to be available to the Company for debt with similar terms and conditions. The fair value of assets and liabilities whose carrying value approximates fair value is determined using Level 2 inputs, with the exception of cash and cash equivalents (Level 1).

Acquisition Agreements

Acquisition Agreements

Pelen, LLC

In January 2018, the Company issued 1,475,410 shares of restricted common stock as initial payment to acquire 25% of the total membership interests of Pelen, LLC. The purchase of the membership interests will close once the seller of the membership interests has received total cash proceeds of at least $0.6 million either through sale of the restricted common stock received or through additional cash payments made by the Company. If all of the shares of restricted common stock have been sold by the seller of the membership interests and the aggregate proceeds received are less than $0.6 million, then the Company is required to pay the shortfall in either additional shares of the Company’s common stock or cash, at the Company’s election. In November 2018, the Company issued 1,758,181 shares of restricted common stock as additional shares based on the shortfall on the aggregate proceeds for the initial shares. In December 2018, the agreement was amended to have a "Cut-Off" date of December 31, 2019, for closing the transaction and any unsold shares will be returned to the Company, with the Company required to make up any shortfall in cash. As of March 31, 2019, the purchase has not closed and the Company has not received legal ownership of the membership interests. As of March 31, 2019, the Company has no make-whole liability recorded as the value of the shares issued based on the March 31, 2019 share price exceeds the value of the remaining purchase price. The Company has recorded a make-whole liability of $0.1 million at December 31, 2018, representing the value of the shortfall based on the actual sales of shares and the share price as of December 31, 2018. This amount is recorded within accrued expenses in the condensed consolidated balance sheet.

Downtown Silver Springs, LLC

The Company entered into an agreement for the purchase of 100% of the membership interests DTSS on May 30, 2018, as amended. DTSS holds a contract for the purchase of approximately 160 acres of centrally located land in Silver Springs, Nevada. DTSS has no other assets, operations or employees.

The Company’s CEO advanced $25,000 to the equity holders of DTSS in 2017, from his own funds. In the second quarter of 2018, the Company was presented with an opportunity to acquire DTSS and, and after disclosure of such advance, the Board of Directors unanimously approved such acquisition.  In connection with the closing of the acquisition of DTSS in August 2018, the equity holders of DTSS repaid $25,000 to the Company’s CEO, without interest or profit.

The agreement to purchase the land allows the holder of the option to purchase the land for approximately $3.2 million, plus 4% interest less deposits made through May 31, 2019 totaling $1.8 million. The current amendment requires DTSS to close on the land purchase by August 30, 2019, with non-refundable deposits of $0.4 million due on June 24, 2019 and $0.3 million due on July 29, 2019 with a remaining balance due of approximately $1.0 million excluding interest.

On February 25, 2019 as amended on June 18, 2019, the Company entered into an agreement to sell its rights in the membership interests of Downtown Silver Springs, LLC (“DTSS”) for $2.5 million plus any additional deposits made by the Company and 3% of the carried interest. The purchaser of DTSS, as well as the Company, under that agreement is allowed to negotiate extensions and different terms with the seller. After closing of the sale of the option by DTSS, the Company will retain a right to receive 3% of the amount of the carried interest that the general partner of the fund that purchased the option is due to receive after all costs, expenses, investor hurdles and returns are deducted from the gross proceeds arising from any gain with respect to such option purchased by the buyer.

The DTSS acquisition was accounted for as an asset acquisition as it was determined that the operations of DTSS do not meet the definition of a business. The Company paid total consideration of $2.1 million, as of March 31, 2019 which consists of (1) $1.6 million cash deposits that will reduce the final purchase price of the land parcel, and (2) $0.5 million cash payments to the former membership interest holders of DTSS ($0.4 million of which has been paid). As the options expire on August 31, 2019, the total consideration has been recorded in prepaid expenses.

As of March 31, 2019, the Company has made non-refundable deposits of $1.6 million which are recorded in prepaid expenses and other current assets in the condensed consolidated balance sheet.

Equity Method Investments and Joint Ventures [Abstract]

Agreements with Tonogold

Agreements with Tonogold

Membership Interest Purchase Agreement

On January 24, 2019, the “Company entered into an agreement with Tonogold (the “Tonogold Agreement”). Under the terms of the Tonogold Agreement, the Company will sell Tonogold its interests in Comstock Mining LLC, a wholly-owned subsidiary of Comstock (“CML”) whose sole assets are the Lucerne Mine properties and related permits. Upon closing, the Tonogold Agreement would replace the October 2017 Option Agreement (the "Option Agreement").

The purchase price for CML is $15 million, plus Tonogold will also guarantee the Company’s financial responsibility for its membership interest in Northern Comstock LLC, who owns and leases certain mineral properties in the Lucerne area, and assume certain reclamation liabilities. The Company also retains a 1.5% net smelter return royalty on the Lucerne properties.

Amendments to Tonogold Agreement

On April 30, 2019, the Company and Tonogold entered into the Purchase Agreement Amendment ("First Amendment)"), which allows Tonogold the option to extend the closing until August 30, 2019, upon the payment of three additional $1 million non-refundable deposits and other considerations. In addition, the First Amendment requires Tonogold to reimburse the Company the monthly interest expense on the Senior Secured Debenture (GF Comstock 2) beginning on June 1, 2019, through the latest possible closing of August 30, 2019.

On May 22, 2019, the Company and Tonogold entered into the Second Purchase Agreement Amendment ("Second Amendment"), which allowed Tonogold to forgo funding the remaining $0.7 million in cash payments due in May, 2019, as required in the First Amendment. The total cash consideration for the Tonogold Agreement remains at $11.5 million in cash. The Second Amendment required that Tonogold issue the Company $3.5 million in convertible preferred shares ("Preferred Shares"), subject to certain pricing conditions and restrictions. Tonogold also issued an additional $0.4 million in Preferred Shares as a commitment fee. The Preferred Shares were issued on June 7, 2019.

The Preferred Shares convert to common shares of Tonogold in two equal tranches after closing the transaction. The first tranche converts upon the four month anniversary of the closing and the second tranche at the twelve month anniversary. The conversion price is the lowest of Tonogold’s (1) 20-day volume weighted closing price prior to conversion, (2) most recent private placement, or (3) initial public offering price. If the closing does not occur within the amended timelines, the stock is automatically convertible at 85% of the then current volume weighted average price.

As of June 7, 2019, Tonogold has paid the Company $2.35 million in non-refundable cash deposits and $3.5 million in non-refundable Preferred Shares associated with the $15 million purchase price with a remaining balance due of $9.15 million.

Option Agreements under Tonogold Agreement

The Company and Tonogold also agreed that commencing upon the closing of the sale of CML, it will enter into a new Option Agreement to lease its permitted American Flat mining property, plant and equipment to Tonogold for crushing, leaching and processing material from the Lucerne mine. Under this new Option Agreement, Tonogold will be required to reimburse the Company for an additional $1.1 million per year to maintain the processing facility lease option. If such option is exercised, Tonogold will then pay the Company a rental fee of $1 million per year plus $1 per processed ton, in addition to all the costs of operating and maintaining the facility, up to and until the first $15 million in rental fees are paid, and then stepping down to $1 million per year and $0.50 per processed ton for the next $10 million paid to the Company.

The Company has also agreed, upon the closing of the sale of CML, to enter into a ten-year mineral lease for additional mineral properties in Storey County, Nevada, granting Tonogold the right to explore, develop and mine these properties. Tonogold will assume approximately $100,000 in annual costs for these properties and will assume work commitments totaling more than $200,000 in 2019. The Company will retain a 3% net smelter return royalty on these additional leased properties, which will be reduced to 1.5% one year after the commencement of mining operations. The lease is renewable for an additional ten-year term.

Existing Option Agreement

On October 3, 2017, the Company entered into the Option Agreement with Tonogold. Under the terms of the Option Agreement, Tonogold has the right to participate in certain activities, including but not limited to, engineering, development, drilling and test-work, towards completing an economic feasibility assessment on certain properties within the Company’s Lucerne resource area (the “Lucerne Property”). The Option Agreement remains in effect until the Tonogold Agreement closes.

Under the terms of the Option Agreement, Tonogold can earn a 51% interest in CML, which owns the Lucerne Property by meeting certain requirements and financial milestones. These requirements and milestones include: (1) making capital expenditures on the Lucerne Property and related expense reimbursements to the Company of $20 million no later than 42-months following the Commencement Date of April 3, 2018, and (2) making option payments totaling $2.2 million to the Company. Tonogold made a $0.2 million option payment on October 3, 2017, and a second and final option payment of $2.0 million on April 3, 2018. The option payments were both recorded within stockholders' equity as they relate to Tonogold’s right to earn-in to a 51% interest in CML. The Company has recognized approximately $0.2 million and $0.2 million in expense reimbursements for the three months ended March 31, 2019, and 2018, respectively.

On April 9, 2019, the Company received $0.2 million from Tonogold for routine reimbursement for monthly expenses and for the remaining balance due on the March 2019 non-refundable deposit.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Use of Estimates

Use of Estimates

In preparing financial statements in conformity with generally accepted accounting principles, we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenditures during the reported periods. Actual results could differ materially from those estimates. Estimates may include those pertaining to estimated useful lives and valuation of properties, plant, and equipment, assets held for sale, mineral rights, deferred tax assets, derivative assets and liabilities, reclamation liabilities, stock-based compensation and payments, and contingent liabilities.

Income Taxes

Income Taxes

We recognize deferred tax assets and liabilities based on differences between the consolidated financial statement carrying amounts and tax basis of certain recorded assets and liabilities and for tax loss carryforwards. Realization of deferred tax assets is dependent upon our ability to generate sufficient future taxable earnings. Where it is more likely than not that the deferred tax asset will not be realized, we have provided a full valuation allowance. The Company has provided a full valuation allowance at March 31, 2019, and December 31, 2018, for its net deferred tax assets because we cannot conclude it is more likely than not that they will be realized.

Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Topic 842 affects any entity that enters into a lease, with some specified scope exceptions. For public business entities, the amendments in this update are effective for financial statements issued for annual periods beginning after December 15, 2018, and interim periods within those annual periods. The Company adopted this guidance on January 1, 2019, with no material impact on the Company’s condensed consolidated financial statements.
