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

American Critical Minerals has voluntarily filed a National Instrument 43-101 Technical Report supporting the exploration targets for Potash, Lithium and Bromine.

• 2.1 billion cubic meters (brine volume) grading from 71.6 to 216.3 parts per million lithium****

2.1 billion cubic meters (brine volume) grading from 3,656 to 4,741 parts per million bromine

Potash Exploration Target of 0.5-1.0 billion tonnes ("Bt") of sylvanite grading from 12% to 18% potassium oxide based on elog (eK2O=19% to 29% potassium chloride based on elog (eKCl))**

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.
