Comstock Mining Completes Lucerne Transaction; Recognizes an $18 million Gain on Sale

VIRGINIA CITY, Sept. 14, 2020 - Comstock Mining Inc. (the “Company” or “Comstock”) (NYSE American: LODE) announced today that it has completed the sale of its Lucerne mine to Tonogold Resources Inc. (“Tonogold”) for total value and consideration of approximately $25.9 million. The consideration includes $7.1 million in cash, $6.1 million in Convertible Preferred Stock (“CPS”), and a $4.475 million, 12% notes receivable, due and payable on September 20, 2021, plus the assumption of $6.7 million in future lease and reclamation obligations, that together represent a permanent reduction of annual operating expenses of approximately $1 million. The CPS had an initial recorded fair value of $7.6 million (and a higher fair value of $10.4 million at June 30, 2020). Comstock retained a 1.5% net smelter return (NSR) royalty on Lucerne and will recognize a tax-free gain on the sale of approximately $18 million, with substantially all of the gain expected in the third quarter.

Mr. Corrado De Gasperis, Executive Chairman and CEO, stated, “This transaction delivered strong value for our shareholders, advanced Lucerne for expansion and growth toward production, and just enabled us to eliminate all of our secured debt, while securing NSR royalties, cost subsidies and future lease revenues for our processing facilities. We are also very excited that Tonogold has commenced drilling associated with their mineral lease to explore, develop and mine properties in Storey County.”

The Company also entered into a long-lived Mineral Lease with Tonogold for additional mineral properties in Storey County, Nevada, granting Tonogold the mineral rights to these properties. Tonogold also announced that it recently completed a $4.25 million equity capital raise, with now over $6 million in cash on hand and an additional $3.5 million in drilling equity credit, fully funding an estimated $7 million drill program, in one of the most historically significant portions of the Comstock Lode. Tonogold’s initial drill program will focus on the nearly 2-mile mineralized strike where most of the historical production and where more favorable mining conditions were enabled by the dewatering of the Sutro Tunnel. Comstock retains a 3% net smelter return royalty on these additional leased properties, reduced to 1.5%, one year after the commencement of mining operations.

Mr. De Gasperis concluded, “Our collaboration with Tonogold has expanded greatly and their recently announced, expansive exploration drilling program is targeting some of the highest-grade sections of the Comstock Lode. We remain a stakeholder and royalty holder, and we very much look forward to the exploration results over the next few months and well into next year. There is a genuine excitement on the Comstock at seeing the core drill rigs turning with great prospects of future high-grade discoveries.”
