Stillwater Critical Minerals Partners with Cornell University on Hydrometallurgy and Carbon Sequestration Initiatives for its Stillwater West Ni-PGE-Cu-Co + Au Project in Montana, USA

Company to Participate in US Department of Energy's MINER Kickoff Event in Austin, Texas

VANCOUVER, BC / ACCESSWIRE / February 14, 2023 / Stillwater Critical Minerals (TSX.V:PGE)(OTCQB:PGEZF)(FSE:5D32) (the "Company" or "SWCM") is pleased to announce it has partnered with Cornell University under the MINER program, funded by the U.S. Department of Energy ("DOE") via the Advanced Research Projects Agency program ("ARPA-E"). Test work, led by Dr. Greeshma Gadikota, will focus on novel hydrometallurgical techniques and carbon capture, with the objective of increasing the extraction of critical minerals using reduced energy for a carbon negative mining future.

Cornell University is the recipient of a federal grant from ARPA-E as part of a program entitled "Supercritical CO2-Based Mining for Carbon-Negative Critical Mineral Recovery". Cornell University seeks to advance CO₂-sourced hydrometallurgical pathways for recovering energy critical metals, including nickel, cobalt, platinum and palladium, coupled to the carbon mineralization of calcium and magnesium components to produce calcium and magnesium carbonates. Novel functional materials for the selective capture and recovery of these energy critical metals will be developed. Various sources for CO₂ will be investigated including air for metal recovery coupled to carbon mineralization. These approaches will be specifically tuned to the mineralogy of the Company's Stillwater West project in Montana.

Dr. Greeshma Gadikota

Dr. Greeshma Gadikota stated, "The U.S. imports the great majority of its energy critical metals from mines all over the world, leaving the U.S. quite vulnerable. Our research is all about decarbonizing the mining industry and developing an independent, domestic supply chain of these critical metals. It's important for U.S. manufacturing, green energy, national security, and competitiveness."

Relating to the Cornell University partnership, Company President and CEO, Michael Rowley, will join Dr. Gadikota at the ARPA-E MINER kick-off event in Austin, Texas on February 14 and 15, 2023. Other presenters and attendees include Tesla Motors, major mining companies, top US government officials and financial institutions.

Michael Rowley, Stillwater Critical Minerals President & CEO, stated, "We are very pleased to be selected as the industry partner for Dr. Gadikota's cutting-edge work and to work closely with her team toward our shared vision of securing the future domestic supply of the critical minerals the US so urgently needs. Our Stillwater West project is rapidly advancing as a potential large-scale, low-carbon source of nickel, copper, cobalt, palladium, platinum and rhodium. Located in an active and expanding US mining district with a long history of critical minerals production and demonstrated world-class scale and grade, Stillwater West is on a very short list of assets with the potential to play a significant role in realizing the goals set out in the bipartisan Inflation Reduction Act, and other ongoing initiatives. It is our belief that mining can do more than supply minerals by conventional means, and that partnerships such as this are the path toward more sustainable practices."

Dr. Gadikota received her PhD in Chemical Engineering and earned her MS degrees in Chemical Engineering and Operations Research, from Columbia University. Her BS in Chemical Engineering is from Michigan State University.

Research Interests

With more than 80% of our energy resources recovered from the subsurface environments which requires about 50 billion cubic meters of fresh water and contributes to more than 75% of global CO₂ emissions, our grand societal challenge lies in meeting our growing demand for energy and resources while reducing environmental impact. Addressing these earth-scale challenges requires us to develop novel technologies to engineer targeted physico-chemical interactions in complex engineered and natural environments. Enabling emergent technologies for a sustainable earth requires us to advance the cross-scale science of fluid-solid interactions in complex and extreme environments. With this perspective, our research is directed towards applications that involve (i) engineering the natural environment for sustainable energy and resource recovery and (ii) designing novel chemical pathways for advancing low carbon and negative emissions technologies.

About ARPA-E

The Advanced Research Projects Agency-Energy (ARPA-E advances high-potential, high-impact energy technologies that are too early for private-sector investment. ARPA-E awardees are unique because they are developing entirely new ways to generate, store, and use energy. ARPA-E projects have the potential to radically improve U.S. economic prosperity, national security, and environmental well-being. We focus on transformational energy projects that can be meaningfully advanced with a small amount of funding over a defined period of time. Our streamlined awards process enables us to act quickly and catalyze cutting-edge areas of energy research.

ARPA-E empowers America's energy researchers with funding, technical assistance, and market readiness. Our rigorous program design, competitive project selection process, and active program management ensure thoughtful expenditures. ARPA-E Program Directors serve for limited terms to ensure a constant infusion of fresh thinking and new perspectives. To learn more visit: https://arpa-e.energy.gov/.

About Stillwater Critical Minerals Corp.

Stillwater Critical Minerals (TSX.V: PGE | OTCQB: PGEZF) is a mineral exploration company focused on its flagship Stillwater West Ni-PGE-Cu-Co + Au project in the iconic and famously productive Stillwater mining district in Montana, USA. With the recent addition of two renowned Bushveld and Platreef geologists to the team, the Company is well positioned to advance the next phase of large-scale critical mineral supply from this world-class American district, building on past production of nickel, copper, and chromium, and the on-going production of platinum group and other metals by neighboring Sibanye-Stillwater. Per an expanded NI 43-101 mineral resource estimate released January 2023, the Platreef-style nickel and copper sulphide deposits at Stillwater West contain 1.6 billion pounds of nickel, copper and cobalt, and 3.8 million ounces of palladium, platinum, rhodium, and gold, in a compelling suite of critical minerals and are open for expansion along trend and at depth.

Stillwater Critical Minerals also holds the high-grade Black Lake-Drayton Gold project adjacent to Treasury Metals' development-stage Goliath Gold Complex in northwest Ontario, currently under an earn-in agreement with Heritage Mining, and the Kluane PGE-Ni-Cu-Co critical minerals project on trend with Nickel Creek Platinum‘s Wellgreen deposit in Canada‘s Yukon Territory.
