Comstock Mining Advances Lucerne Sale; Receives Additional Non-refundable Deposit and NYSE Notifications

VIRGINIA CITY, June 27, 2019 - Comstock Mining Inc. (“Comstock” or “the Company”) (NYSE American: LODE) today announced that Tonogold Resources Inc. (“Tonogold”) (OTCMKTS: TNGL) has paid an additional non-refundable cash deposit of $600,000 toward the purchase of the Company’s Lucerne properties.

On January 24, 2019, the Company entered into an agreement with Tonogold to sell its Lucerne properties for $15 million ($11.5 million in cash and $3.5 million in stock). On June 21, the Company entered into a Third Purchase Agreement Amendment that provides for Tonogold to deliver $11.5 million in cash at closing, less the total amounts of the cumulative non-refundable cash payments made by Tonogold at that time, now totaling $2.95 million. Tonogold can pay an additional non-refundable cash deposit of $400,000 applicable to the closing price or $400,000 in stock that is not applicable to the closing price.

Mr. Corrado De Gasperis, Executive Chairman and CEO, stated, “Tonogold’s payments reflect their commitment for acquiring and advancing the Lucerne project back into production. We have now received nearly $7 million in cash and stock payments, with another $400,000 due this week. We look forward to closing this transaction this summer, eliminating our debenture and accelerating our strategic growth plans.”

This deposit will result in the paydown of an additional $420,000 in Debenture principal, reducing the balance to $6.8 million and extends the closing deadline to July 26, 2019. Tonogold retains the option to extend the closing one additional month, until August 30, 2019, by paying an additional, $1 million non-refundable cash deposit (or $500,000 cash applicable to the purchase price plus $500,000 of convertible preferred stock not applicable to the purchase price). Tonogold is also required to reimburse the Company for the interest expense on the Company’s Senior Secured Debenture, and for operating expenses from the American Flat platform, from June 1.

On June 21, 2019, the NYSE American LLC (the “NYSE”) notified the Company that it was back in compliance after filing the Company’s March 31, 2019, Form 10-Q. On June 24, 2019, the NYSE notified the Company that its securities have been selling at or below $0.20 per share since May 20, 2019, and that its continued listing is predicated on demonstrating sustained price improvement within the next six month period, that is, no later than December 24, 2019, or effecting a reverse stock split. The Company meets all other listing requirements and its common stock will remain listed on the NYSE and believes its business strategy will regain sufficient share price levels. The NYSE American notification does not affect the Company’s business operations or its SEC reporting requirements and does not conflict with or cause an event of default under any of the Company’s material agreements. The Company’s common stock will continue to trade under the symbol “LODE,” while under the below compliance (that is, “.BC”) designation until the price is elevated and designation is removed.

Mr. De Gasperis, concluded, “We believe the NYSE is the best stock exchange in the world and could not be more appreciative of their ongoing support. We admire the quality and recognition of the NYSE’s reputation, and appreciate the liquidity and protections it provides and will continue providing, for all of our shareholders.”
