AMERICAN CRITICAL MINERALS APPLAUDS THE NEWLY UPDATED 2025 U.S. GEOLOGICAL SURVEY LIST OF CRITICAL MINERALS NOW INCLUDING BOTH POTASH AND LITHIUM

American Critical Minerals Corp. has noted the USGS (U.S. Geological Survey) recently updated the Secretary of the Interior, acting through the director of the USGS and has now finalized the 2025 list of critical minerals to include both potash and lithium. The updated list emphasizes "critical minerals are essential for national security, economic stability and supply chain resilience because they underpin key industries, drive technological innovation and support critical infrastructure vital for a modern American economy." Furthermore, the notice goes on to state "The nation possesses vast mineral resources that can create jobs, fuel prosperity and significantly reduce our reliance on foreign nations, and the United States is taking actions to facilitate domestic mineral production. The list of critical minerals guides strategies to secure the nation's mineral supply chains."

Simon Clarke, president and chief executive officer, stated: "This timely announcement further underpins the importance of unlocking the potential of both potash and lithium within our Green River project. Now with our recent bought deal financing closed and our technical team expanded with the appointment of Dean Pekeski, we can focus on executing our carefully designed phased drilling program(s) to confirm historical data and work towards maiden resources for both potash and lithium."

About American Critical Minerals' Green River potash and lithium project

The Green River potash and lithium project is situated within Utah's highly productive Paradox basin, located 20 miles northwest of Moab, Utah. It has significant logistical advantages including close proximity to major rail hubs, airport, roads, water, towns and labour markets. It also benefits from close proximity to the agricultural and industrial heartland of America, and numerous potential end-users for its products.

The history of oil and gas production across the Paradox basin provides geologic data from historic wells across the project, and the wider basin, validating and derisking the potential for high-grade potash and large amounts of contained lithium. Wells in and around the project reported lithium up to 500 ppm (parts per million), bromine up to 6,100 ppm and boron up to 1,260 ppm (Gilbride & Santos, 2012). These data are reinforced by nearby potash production and the advanced stage of neighbouring lithium projects. The Paradox basin is believed to contain up to 56 billion tonnes of lithium brines, potentially the largest such resource in the U.S.

The company's National Instrument 43-101 -- Standards of Disclosure for Mineral Projects (NI 43-101) potash exploration target consists of 500 million to 950 million tonnes of sylvinite (the most important source for the production of potash in North America) grading from 12 per cent to 18 per cent potassium oxide based on elog (eK2O equals 19 per cent to 29 per cent potassium chloride based on elog (eKCl)). Its exploration targets for lithium and bromine are 2.1 billion cubic metres (brine volume) grading from 71.6 to 216.3 parts per million lithium; and 2.1 billion cubic metres (brine volume) grading from 3,656 to 4,741 parts per million bromine.

The company holds a 100-per-cent interest in 11 State of Utah (SITLA) mineral and minerals salt leases covering approximately 7,050 acres, 1,094 federal lithium brine claims (Bureau of Land Management placer claims) covering 21,150 acres, and 11 federal (BLM) potash prospecting permits covering approximately 25,480 acres. Through these leases, permits and claims the company has the ability to explore for potash, lithium and potential byproducts across the entire Green River project (approximately 32,530 acres). The company is authorized to drill a total of seven drill holes across the project (pending bonding the recently approved four drill holes).

Intrepid Potash Inc. is America's largest potash company and only U.S. domestic potash producer and currently produces potash from its nearby Moab solution mine, which the company believes provides strong evidence of stratigraphic continuity within this part of the Paradox basin. Anson Resources Ltd. has advanced lithium development projects contiguous to the northern boundary of the company's Green River project and neighbouring to the south. Anson has a large initial resource, robust definitive feasibility study and has recently completed successful piloting operations through its partnership with Koch Technology Solutions, as well as an offtake agreement with LG Energy Solution. The Anson exploration targets encompass the combined Mississippian Leadville formation and the Pennsylvanian Paradox formation brine-bearing clastic layers, which also underlie American Critical Minerals' entire project area.

In 2022, the U.S. imported approximately 96.5 per cent of its annual potash requirements with domestic producers receiving a higher sales price due to proximity to market. In March, 2024, the U.S. Senate introduced a bill to include key fertilizers and potash on the U.S. Department of Interior list of critical minerals which already includes lithium, and this process is well advanced with potash being added to the USGS draft critical minerals list in August, 2025. Recent market estimates suggest that the global potash market is over $50-billion (U.S.) annually and growing at a compound annual growth rate (CAGR) of close to 5 per cent. Annual lithium demand is now estimated to be over one million tonnes globally and continuing to grow rapidly.
