Comstock Mining Announces Accelerated Payment on Lucerne Transaction; Tonogold Accelerates $3.5 million Stock-based Down Payment

VIRGINIA CITY, May 23, 2019 - Comstock Mining Inc. (“Comstock” or “the Company”) (NYSE American: LODE) today announced a further update and progress toward the completion of the sale of its Lucerne properties (“Lucerne”). Tonogold Resources Inc. (“Tonogold”) has accelerated paying the non-refundable, $3.5 million stock-based component of the purchase price, representing 3500 Shares of Convertible Preferred Stock with a stated value of $1,000 per share plus a commitment fee of an additional 420 Shares of Convertible Preferred Stock with identical terms, in lieu of the $650,000 cash payment due this month. This payment maintains the deadline for closing the transaction until June 21, 2019.

On January 24, 2019, the Company entered into the Tonogold Agreement for the sale of its Lucerne properties to Tonogold for $15 million (representing $11.5 million in cash and $3.5 million in stock). This Amendment simply reflects the acceleration of the $3.5 million stock-based component of the purchase price, previously agreed upon, in lieu of the $650,000 cash payment due this month. The $3.5 million will be paid in a Convertible Preferred Stock with the post-closing conversion price being the lowest of (1) the 20-day volume weighted closing price of Tonogold shares prior to conversion, (2) Tonogold’s most recent private placement or (3) Tonogold’s 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.

Mr. Corrado De Gasperis, Executive Chairman and CEO, stated, “The early receipt of this payment from Tonogold demonstrates the good, ongoing progress towards finalizing the Lucerne transaction. We have now received almost $6 million in cash and stock out of the $15 million closing component of the purchase price, plus the additional commitment fee. We look forward to closing this transaction in June, eliminating our debenture and accelerating the deployment of our strategic growth plans.”

The Amendment does not change the requirement that Tonogold reimburses the Company for the monthly interest expense on the Company’s Senior Secured Debenture, and the more than $1 million in annual operating expenses associated with the American Flat platform, both effective and beginning on June 1, 2019, regardless of when the sale closes. Tonogold also retains the option to extend the closing for two additional months, upon the payment of two additional, $1 million non-refundable deposits.

Comstock anticipates 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, currently totaling $2.35 million.
