VANCOUVER, British Columbia, September 22, 2026 /CourierPR/ -- American Critical Minerals Corp. ("American Critical Minerals" or the "Company") (CSE:KCLI)(OTCQB:APCOF)(Frankfurt:2P3) has successfully completed drilling and coring operations at the Duma Point AP-S-02 well, located at the company's Green River Project, situated 20 miles west of Moab, Utah. The well, strategically positioned approximately 2,000 feet from a historic oil and gas well, validated historical drill data that reported 5.9 meters grading 24.3% KCl within Cycle 5. The well was completed at a total depth of 2,818 meters (9,245 feet) on September 13, 2026, signaling a key milestone for the project and the Company.
The Duma Point AP-S-02 well was designed to validate historic drill data and test the key Paradox formation potash horizons as well as the clastic brine-bearing zones for lithium and bromine in the Paradox and Leadville formations. During initial on-site core handling and visual logging of the recovered core, the company confirmed the presence of sylvite mineralization within the Cycle 5 potash bed. The well also fully intersected the Paradox and the upper Leadville formations, encountering all expected clastic and limestone units that could be sources of lithium and bromine-bearing brine.
The completed wireline data provided positive support for the presence of the Cycle 5 potash unit, consistent with historic drilling results from the Quintana Fed 1-1 well, located approximately 0.6 kilometers (2,000 feet) east-northeast of the current well. The Quintana Fed 1-1 well intersected the Cycle 5 potash bed reporting a grade of 24.3% eKCl from elogs over a thickness of 5.9 meters (19.4 feet). Interpretation of the wireline geophysical responses from the Duma Point AP-S-02 well indicated that the targeted potash intervals occur at depths and apparent thicknesses consistent with those identified in the historically completed Quintana Fed 1-1 well.
The Cycle 5 potash core is currently being logged, photographed, and prepared for shipment to the Saskatchewan Research Council (SRC) in Saskatoon, Saskatchewan, where it will undergo detailed geochemical analysis. The Company will provide updates as results become available.
The downhole wireline geophysical logs also allowed for the interpretation of potential lithium and bromine brine aquifers within the Paradox and Leadville formations. Two drill stem packer tests were completed targeting the Leadville Formation limestone unit and lower clastic units of the Paradox Formation. These formations are the same geologic units that Anson Resources Ltd. has been developing as part of their lithium development projects contiguous to the northern and southern boundaries of the Company's Green River Project.
Brine was successfully sampled from both of these units and will be submitted to ACZ Laboratories, Inc. located in Steamboat Springs, Colorado. The Company will provide updates as results become available.
The well has been cemented and abandoned according to requirements and stipulations found within the State permit for the well. It is expected that the rig will be demobilized by approximately September 25, 2026.
American Critical Minerals 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 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 labor 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 neighboring lithium projects. The Paradox Basin is believed to be one of the biggest sources of lithium brines in the United States.
