Star Metro - American Critical Minerals Files Technical Report for Green River Potash and Lithium Project

VANCOUVER, BC / ACCESS Newswire / October 28, 2025 / American Critical Minerals Corp. ("American Critical Minerals" or the"Company") (CSE:KCLI)(OTCQB:APCOF)(Frankfurt:2P3) is pleased to announce that that the Company has filed a National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") Technical Report supporting the Exploration Targets for Potash, Lithium and Bromine for its Green River Potash and Lithium Project, reported in the Company's news release dated October 6, 2025. The NI 43-101 Report was prepared by Biao Qiu, Ph.D., P.E., P.Eng. and Deliang Han, Ph.D., P.Geo. of Agapito Associates, LLC., dated October 27, 2025. The Exploration Targets have an effective date of September 30, 2025. The filing is voluntary and is not required under NI 43-101 (see Part 4.2(12) of Companion Policy 43-101CP).

The NI 43-101 Report recommends a phased exploration and development program, to build on and confirm historic oil and gas drill data and seismic work, including but not limited to Phase 1: Drilling to test Cycle 5 Potash horizons and test the clastic zones for both Lithium and Bromine within the Paradox and Leadville Formations; complete maiden mineral resource estimates for Potash, Lithium and Bromine; and, complete initial pre-feasibility studies thereon. Phase 2: Additional step out drilling; run a Vertical Seismic Profile ("VSP") in at least one well for the purpose of generating a synthetic seismogram to improve the analysis of existing two-dimensional ("2D") seismic interpretation; conduct a 3D seismic survey; complete Lidar Surface mapping; conduct a deep disposal well study; conduct detailed engineering and design; conduct baseline environmental studies; all culminating in a feasibility study and the commencement of permitting. Based on the recommendations, the Company is currently working to develop the phase 1 program of drilling and sampling for the upcoming season.

Simon Clarke President & CEO stated, "We updated the existing technical report to include the recently announced lithium and bromine exploration targets. This also provided an opportunity to include an up-to-date analysis on historic seismic data and to update the prior report for the recent approval of our Plan of Operations, Federal Potash Prospecting Licenses and Drill Authorizations and to update recommendations based on latest developments in the area and exploration in general.

We believe, we now have a very detailed and up to date analysis of our Project and its broader potential. The recommendations from the Report will help form the basis of our upcoming drilling and sampling program where we will drill test the Tier 1 Targets and move towards maiden mineral resources for Potash, Lithium and Bromine".

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 and 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 contain up to 56 billion tonnes of lithium brines, potentially the largest such resource in US (Source: Anson Fastmarkets Presentation - https://wcsecure.weblink.com.au/pdf/ASN/02823465.pdf).

The Company's 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% to 18% potassium oxide based on elog (eK2O=19% to 29% potassium chloride based on elog (eKCl)). Its Exploration Targets for Lithium and Bromine are 2.1 billion cubic meters (brine volume) grading from 71.6 to 216.3 parts per million lithium; and 2.1 billion cubic meters (brine volume) grading from 3,656 to 4,741 parts per million bromine.**

The Company holds a 100% interest in eleven State of Utah ("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 Project (pending bonding the recently approved 4 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 (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***.

****Exploration Targets are conceptual in nature and there has been insufficient exploration to define them as Mineral Resources, 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.

**A report titled "NI 43-101 Technical Report - Green River Potash and Lithium Project, Grand County, Utah, USA", prepared by Agapito Associates Inc., and dated October 27, 2025, quantifies the Green River Potash Project's potash, lithium and bromine exploration potential in the form of NI 43-101 Exploration Targets. The Exploration Target estimate was prepared in accordance with NI 43-101. It should be noted that Exploration Targets are conceptual in nature and there has been insufficient exploration to define them as Mineral Resources, 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. Details of the basis on which the Exploration Targets have been determined is included in the Report. The Exploration Target stated in the Report is not being reported as part of any Mineral Resource or Mineral Reserve.
