Mr. Corrado DeGasperis, Executive Chairman and CEO stated, “We are on track to land the MCU - Comstock system this week, equipment started to arrive yesterday, and to commence testing within the boundaries of the Carson River Mercury Superfund Site (“CRMSS”). We are finalizing the requirements for shipping the first international unit to the Philippines and have scheduled deployment to the Davao D’Oro Province. We are accelerating the pace of deployment as we continue to invest in clean, precious-metal based growth.”

Comstock Mining’s Corporate Growth

The Company has enacted its Board-approved transformational strategic plan, focused on high-value, cash-generating, precious metal-based activities, (the “Strategic Focus”) including, but not limited to, environmentally friendly, and economically enhancing mining technologies, like mercury remediation. Our goal is to deliver over $500 million of value from our existing assets and the commercialization of these environmental mining technologies, partnerships and ventures. Comstock Mining Inc. is the parent company that wholly owns the realigned subsidiaries and is expanding its mercury and royalty portfolios. We believe that our resource-based technology, properties, plant and equipment and existing gold and silver resources are deeply undervalued.

Our realignment repositions the Company for clean, sustainable growth, and we are now growing.

Mr. DeGasperis continued, “The realignment enables partnerships and transactions that increase value-creating opportunities and accelerates our precious-metal based growth. Since the realignment, we have expanded our partnership with both MCU and Tonogold. The MCU investments provide broad opportunities for higher, faster returns and long-lived cash flows. We are working closely with all our partners to grow value.”

Comstock Mercury Remediation System and the American Flat Processing Platform

Our American Flat processing platform is fully permitted, and the infrastructure has been prepared, including pads, power, water and retaining walls, for the delivery of the brand new MCU mercury remediation system. The system is scheduled to ship this week and peripheral equipment has already begun arriving. The Company is collaborating directly with U.S. and Nevada regulators and policy makers for maximum social and environmental impact.

The Company and MCU have prepared the site for delivery of this impressive aggregation of state-of-the-art alluvial mining technologies, operating as one, fully integrated mercury remediation system. The system, which is mobile, stands almost twenty feet high and comes with an additional, specialized, mobile metallurgic laboratory and an integrated Dissolved Air Flotation (DAF) system, one of the most effective, mobile wastewater reuse operations.

MCU’s Mercury Remediation System - for the Philippines

Oro Industries has manufactured this second, state-of-the-art mercury remediation system for our newly created MCU Philippines Inc. (“MCU-P”) entity, in partnership with our partner Clean Ore Solutions (“COS”), with whom we have a Joint Venture to establish Clean Mineral Recovery Technologies (“CMRT”) for remediation and rehabilitation of the mercury-contaminated Naboc River on Mt. Diwata, in Davao D’Oro, Philippines.

CMRT will work directly with the Philippine Department of Environment and Natural Resources (DENR) and the provincial government of Davao D’Oro for the rehabilitation of this mine-waste contaminated river.

Non-mining Assets

Our non-mining assets are now valued at over $25 million, net of debt. We have agreements to sell the Industrial and Commercial lands plus the senior water rights in Silver Springs, for over $10 million, and now expect those sales to close in September 2020. These proceeds will be used to extinguish approximately $5 million in debt obligations (including our $4.1 million Debenture). Our $6.1 investment in Tonogold Convertible Preferred Stock (CPS) is now valued at $10.4 million based on the $1.1 million in CPS shares that we have already converted into 6.111,111 common shares at Tonogold’s current share price. We are also owed approximately $4.9 million from Tonogold through a 12%, cash interest paying forward instrument, with principal payments of $0.4 million due this October 2020, and $4.475 million due September 2021.

Corporate

The Company received a $0.5 million early payment in June 2020, on obligations owed from Tonogold and reduced our Senior Debt principal down to $4.1 million in mid-July, down from $4.5 million at June 30, 2020. Cash and cash equivalents at June 30, 2020, were $1.0 million, and the Company raised an additional $1.25 million on July 22, 2020, primarily for growth investments in MCU Philippines Inc., bringing total common shares outstanding at July 28, 2020, to 31,981,105 shares, as compared to 28,815,000 shares, at June 30, 2020.

Outlook

During the third quarter of 2020, the Company expects to close on the sale of certain non-mining assets located in Silver Springs, NV, to Sierra Springs Enterprises Inc., for total proceeds of approximately $10 million. The agreements, as amended, included $0.4 million of non-refundable deposits made and released to the Company from escrow. The Company will use the remaining proceeds to extinguish the entirety of its outstanding Senior Secured Debenture principal and make-whole, of approximately $4.3 million, plus accrued interest of less than $0.1 million.

Tonogold is currently permitting a drilling program for the Storey County exploration targets, including the leased mineral claims, just north of the Lucerne area, and expects to begin drilling in the third quarter of 2020. As of June 30, 2020, Tonogold has earned 54.57% of the membership interest after making payments of over $6.5 million in cash and $6.1 million in CPS. The Company expects to monetize approximately $0.5 million worth of common shares in the second half of 2020, depending on price and liquidity, under an existing 10b5-1 plan.

The Company’s second half 2020 plans also include obtaining the local permits for Dayton, expanding Dayton’s current resource and continuing 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 a new, SK-1300 compliant, mineral resource estimate.

For 2020, the Company’s plans include advancing the investment in and the commercialization of MCU’s mercury remediation processing technologies. The Company expects to close on the MCU transactions during the fourth quarter of 2020, meaning, at that time, it will own 25% of MCU and 50% of its first joint venture in the Philippines. Oro has completed the manufacture of the 25-ton-per-hour mercury recovery plant and is shipping the system to the Comstock, including a 200 gallon-per-minute dissolved air flotation water treatment plant, this week.

MCU has commenced trial operations that will continue throughout the second half of 2020, at the Company's American Flat processing facility, to validate and fine-tune the mercury extraction and remediation process, with the objective of reclaiming and remediating the Company's existing properties within the Carson River Mercury Superfund Site ("CRMSS"), enhancing the values of, and evaluating the potential economic feasibilities for, these properties and creating new global growth opportunities in mercury remediation by demonstrating MCU’s technological and operational effectiveness, efficiency, and feasibility.

MCU-P has agreed and plans to commence reclamation operations during the third quarter 2020, in the Philippines. MCU-P will operate under a joint venture agreement with Clean Ore Solutions, a Philippine Company, for mercury extraction and remediation of Mt. Diwata and the Naboc River, one of the most mercury polluted, gold mining regions in the world. This represents the first real international opportunity for large-scale mercury remediation and environmental reclamations, using MCU’s systems, with the objective of establishing MCU a leader in mercury remediation projects, and in particular, contaminations caused by Artisanal and Small-Scale Miners (ASM).

Our annual operating expenditures, including other cash income and expenditures and excluding depreciation, are planned at approximately $5.5 million, with approximately $2.5 million of that amount currently being reimbursed under the Tonogold Purchase Agreement, Lease-Option Agreement, and Mineral Exploration and Mining Lease Agreement, resulting in net operating expenses for 2020, excluding exploration spending, of $3 million. During the first six months of 2020, the Company received approximately $1.25 million in expense reimbursements and $1.0 million in cash for prepaid reimbursements required under the Tonogold agreements and expects to receive another $0.2 million during the fourth quarter of 2020.
