American Critical Minerals Completes Drilling Operations at the AP-S-02 Duma Point Well Confirming Potash Mineralization and Deep Brine Aquifers
American Critical Minerals completed drilling and coring at its Duma Point AP-S-02 well on the Green River Project in Utah's Paradox Basin, reaching a total depth of 2,818 metres (9,245 feet) on September 13, 2026. Initial visual logging confirmed sylvite mineralization in the Cycle 5 potash bed. Wireline geophysical data shows potash intervals at depths and thicknesses consistent with the historic Quintana Fed 1-1 well, which reported 24.3% eKCl over 5.9 metres. The well also intersected prospective brine zones in the Paradox and Leadville formations, with brine samples sent to ACZ Laboratories and potash core headed to the Saskatchewan Research Council for geochemical analysis.
