Comstock Mining Inc. Releases Shareholder Letter

Dear Shareholders:

On behalf of our Board of Directors, our employees, and partners, we thank each of you for participating in a pivotal year for Comstock, in which we completed a series of strategic transactions that acquired intellectual property, management, employees, and the facilities needed to transform our business and establish a platform of breakthrough renewable energy products. We have aligned on a precise goal, and we are eager to summarize our business plans and our outlook for you, here and now.

The Comstock

The Comstock Lode is one of world's most important mineral discoveries. It has a rich history, steeped in grit and innovation. Its pioneers innovated new technologies and mined over $20 billion in gold and silver (in today's dollars), infusing extraordinary wealth into America's burgeoning economy at the dawn of the industrial revolution. We have been proud to inherit and contribute to that legacy throughout our own history, as we enabled an unprecedented consolidation and operation of the historic Comstock Lode mining district, including 10-square miles of land with many miles of known mineral claims and exploration targets. We mined and produced about 60,000 ounces of gold and 735,000 ounces of silver from just one of those targets between 2012 and 2016. We believe that far more remains, a bonanza with billions of dollars of gold and silver, unavailable to the century-old mining practices of our predecessors. Our strategic partners are working to unlock that value.

Accordingly, we shifted our focus during 2020 and 2021 to new investments in renewable energy, where we have differentiated technology and core competencies, while monetizing our non-strategic assets. Our objectives are to maximize the value from our mineral estate while introducing breakthrough, decarbonizing lines of business with the capacity for rapid growth.

Enabling Systemic Decarbonization - Cellulosic Fuels

Renewable fuels provide a critical pathway for decarbonization, however, most current forms of renewable fuel draw from the same pool of conventional feedstocks, including corn and various vegetable oils in the U.S., and the entire universe of those feedstocks only represents a tiny fraction of the global motor fuel burn. Further, the lifecycle carbon benefits of growing, harvesting, and using conventional feedstocks are extremely limited, even in comparison to fossil fuels. Any plan to meaningfully decarbonize using renewable fuels must involve abundant and available feedstocks that no one else is using today.

Our renewable fuels division, Comstock Fuels, acquired a portfolio of pioneering technologies that resolve conventional feedstock limitations by efficiently converting wasted, unused, widely available, and rapidly replenishable woody biomass into advanced cellulosic fuels. These technologies unlock vast quantities of historically unused and underutilized feedstocks with enough renewable carbon to permanently offset billions of tons of fossil fuel emissions.

According to the U.S. Department of Energy, America can produce upwards of one billion tons per year of biomass feedstock for renewable fuels. That's enough to produce 1.7 billion barrels of carbon neutral fuels with our technologies, or more than a third of the U.S. transportation demand. In addition, more than 27% of American soil, or about 540 million acres, is comprised of forestland that was previously more than twice as large, before being clear cut for less productive uses. Those under-utilized resources could be restored and used to sustainably grow, harvest, and replant billions of tons of fast-growing trees and energy crops for conversion into billions of barrels of renewable fuels with our technologies. The combined output could exceed 50% of America's current annual output of fossil crude, and it's 100% renewable. Canada has even more. It's the equivalent of an oil well that will never run dry, a bonanza hidden in plain sight, and our technologies are effectively the drill.

Enabling Systemic Decarbonization - Electrification Products

Electrification and continued advancements in energy storage are vitally necessary to reduce reliance on fossil fuels while shifting to and increasing use of renewable fuels. Our 90% owned lithium-ion battery ("LIB") recycling business, LiNiCo Corporation ("LiNiCo"), holds the rights to a portfolio of innovative processes that efficiently crush and separate LIBs, extract lithium, nickel, cobalt, and graphite, and reuse the recovered metals to produce 99% pure cathode active precursor products. Collectively, these technologies give LiNiCo, and its existing 137,000 square foot battery metal recycling facility, differentiating competitive advantages, including the ability to process upwards of 100,000 tons of LIB and related feedstocks per year into an array of electrification products, including lithium, nickel, cobalt, graphite, and cathode materials.

According to International Energy Agency ("IEA"), there were more than 10 million electric vehicles ("EVs") on the road in 2020, with new EV registrations increasing by 41% over 2019 and another 140% during the first quarter of 2021. Meeting the increased EV demand is estimated to require about five times more lithium carbonate equivalent ("LCE") than the entire lithium mining industry produces today. Miners and manufacturers can scale up to meet that demand, however, according to a January 2021 USGS mineral commodity summary, there are only about 86 million tons of identified lithium reserves worldwide, and LIBs are typically landfilled after eight to ten years of use. Our technologies meet the realities of that demand by enabling profitability at the earliest stages of production, thereby positioning our LIB recycling business to contribute billions to our enterprise value from LiNiCo based on existing valuations of comparable public companies.

Our Outlook - A Net Zero Carbon World

This is our new platform for growth. We will innovate and commercialize technologies that contribute to global decarbonization and net zero circularity by efficiently converting natural resources, including wasted and unused materials, into valuable renewable energy products that shift supply chains away from and reduce reliance on fossil fuels. We will also lead and support the adoption and growth of a balanced net zero ecosystem based on the feedstocks unlocked by our technologies, with powerful embedded economic incentives for our clients, their industries, and the populations they serve to decarbonize.

We will rapidly achieve exponential growth and extraordinary financial, natural, and social gains by building, owning, and operating a fleet of advanced carbon neutral extraction and refining facilities, by selling an array of complimentary process solutions and related services, and by licensing selected technologies to qualified strategic partners. Our goal is to generate over $16 billion in revenue on an annualized basis by 2030, by producing and selling renewable energy products that enable us, our clients, and their downstream stakeholders to reduce greenhouse gas emissions by at least 100 million metric tons per year. Meeting that objective would offset more than 234 million barrels per year of fossil fuel, or about 6% of the U.S. transportation burn, and require an estimated 8% of the existing biomass residues produced annually in the U.S.

Such scales are achievable by tapping into and leveraging existing infrastructure. Our expanded team has extensive experience in the renewable fuels industry, having designed and built several dozen renewable fuel production facilities in the U.S. Notably, our team invented and commercialized pioneering processes used by more than 95% of the U.S. corn ethanol industry to produce distillers corn oil, a value-added feedstock that offsets more than 20 million barrels of fossil fuel per year and has played a disruptive role in the growth and development of the renewable fuels industry.

We have already made remarkable progress. We are currently building commercial pilot scale cellulosic fuels and LIB facilities, and we are preparing to commence operations at our full-scale LIB recycling facility later this year. We have also made significant strides in developing and establishing our new facilities and forging new revenue and licensing streams that we will soon share. We have also made meaningful progress and will complete the monetization of our non-strategic assets, as quickly as possible, while funding our new businesses and limiting our focus to the objectives outlined above.

The Comstock Lode's history of relentless grit and innovation and pioneering and prospecting against all odds will always be part of our identity. Moving forward, we will drop the word "mining" from our name and rebrand the company as "Comstock" to reflect our new mission of enabling systemic decarbonization. Additional information in that regard will be made available in the coming weeks as we launch our new website and file our Form 10-K for our fiscal year ended December 31, 2021.

We look forward to our next communication and seeing those of you that can attend this year's Annual General Meeting, on May 26, 2022, where we plan on showcasing our renewable energy businesses, employees, and partners, including the results of our business plans, schedules, and near-term revenues. Until then, thank you for your continued interest and support.

Kindest regards,
Corrado De Gasperis
