The GIGA USA Conference brings together government officials, financiers and industry participants from across the critical minerals sector for two days of networking, deal-making, and policy discussions focused on U.S. energy security. The Company will participate in meetings with government representatives and bodies and other strategic parties during this conference to highlight how the advancement of the Green River Project can help strengthen domestic U.S. supply chains for strategic batteries and minerals and those required for food security. The Company intends to engage with investors, and strategic industry participants and stakeholders as it looks to drive exploration and development of its Green River Project.

American Critical Minerals will be represented by the CEO, Dean Pekeski who, in addition to his deep technical knowledge on potash discovery, development, and extraction, has also successfully applied for US Government Funding from a number of Agencies including the U.S. Department of Agriculture ("USDA") and the Export-Import Bank of the United States ("EXIM"). These strong relationships within Government Agencies will be leveraged as the Company explores Government funding opportunities. Chairman, Simon Clarke, who has been focused on Critical Minerals development for over 10 years, including serving as the CEO of American Lithium and has previously presented to a number of Government Agencies will also attend. Eric Miller, a Director of the Company and President of Washington D.C. based Potomac Strategy Group and has extensive experience advising Critical Mineral companies on Government initiatives and advancing their interests, will also attend.

Dean Pekeski, CEO & President of the Company stated: "We are looking forward to attending the Benchmark GIGA USA 2026 conference in Washington, D.C. This will be a great opportunity for us to network with key lithium producers, developers, and explorers and other strategic parties and investors.

About American Critical Minerals' Green River Potash and Lithium Project

The Green River 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 de-risking the potential for high grade potash and large amounts of contained lithium. Wells in and around the project reported lithium up to 500 ppm, bromine up to 6,100 ppm and boron up to 1,260 ppm (Gilbride & Santos, 2012). This data is reinforced by nearby potash production and the advanced stage of neighbouring lithium projects. The Paradox Basin is believed to be one of the biggest sources of lithium brines in the United States. (Source:AnsonFastmarketsPresentation - https://wcsecure.weblink.com.au/pdf/ASN/02823465.pdf).

The Company has disclosed targets for further exploration at the Green River Project consisting of 500 million to 950 million tonnes of sylvinite (the most important source for the production of potash in North America) grading from 12% to 18% potassium oxide based on elog (eK2O=19% to 29% potassium chloride based on elog (eKCl)). Its target for further exploration for Lithium and Bromine is 0.6-1.7 Mt lithium carbonate equivalent grading from 91-152 ppm; and 3.3-9.1 Mt bromine grading from 2,647-4,412 ppm.**

The Company holds a 100% interest in eleven SITLA mineral and minerals salt leases covering approximately 7,050 acres, 1,094 federal lithium brine claims (BLM 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 by-products across the entire Green River Project (approx. 32,530 acres). The Company is authorized to drill a total of 7 drill holes across the Green River Project.

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 (www.intrepidpotash.com). Anson Resources Ltd. has advanced lithium development projects contiguous to the northern boundary of our 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 (www.ansonresources.com).***

In 2022, the U.S. imported approx. 96.5% of its annual potash requirements with domestic producers receiving a higher sales price due to proximity to market (intrepidpotash.com/ August 15, 2024, Investor Presentation). In March 2024, the US Senate introduced a bill to include key fertilizers and potash on the US 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 US$50 billion annually and growing at a compound annual growth rate ("CAGR") of close to 5%. Annual lithium demand is now estimated to be over 1 million tonnes globally and continuing to grow rapidly.****

The scientific and technical content of this news release has been reviewed and approved by Dean Besserer, P.Geo., the Chief Operations Officer of the Company and a qualified person for the purposes of NI 43-101.

*Historical data disclosed in this news release relating to historical wells from previous operators are historical in nature. Neither the Company nor a qualified person has yet verified this data and therefore investors should not place undue reliance on such data. The Company's future exploration work may include verification of the data. The Company considers historical results to be relevant as an exploration guide and to assess the mineralization as well as economic potential of exploration projects. Any historical well data disclosed are selective and may not represent true underlying mineralization. Please refer to the report titled "Amended and Restated NI 43-101 Technical Report, Green River Potash and Lithium Project, Grand County, USA' dated January 27, 2026, and available under the Company's profile at www.sedarplus.ca.

** The potential quantity and grades are conceptual in nature and there has been insufficient exploration to define a mineral resource, and, while reasonable potential may exist, it is uncertain whether further exploration will result in the determination of a mineral resource under NI 43-101. Targets for further exploration for potash, lithium and bromine at the Green River Project are used to provide a conceptual estimate of the potential quantity and grade of a mineral deposit, based on known and additional limited geological evidence. It is an early-stage assessment that will help to guide further exploration, but it is not a mineral resource or mineral reserve and should not be treated as such. The report titled "Amended and Restated NI 43-101 Technical Report, Green River Potash and Lithium Project, Grand County, USA' dated January 27, 2026, and available under the Company's profile at www.sedarplus.ca provides details of the basis on which the targets for further exploration have been determined.

*** American Critical Minerals' management cautions that results or discoveries on properties in proximity to the American Critical Minerals' properties may not necessarily be indicative of the presence of mineralization on the Company's properties.
