(TSX:ASCU | OTCQX:ASCUF)\n \n (“ASCU” or the “Company”) is pleased to announce the completion of both the infill to Indicated Pre-feasibility Study (“PFS”)-related drilling program and a Cactus West step out drill program for a total of 232,000 ft (70,715 m), at the Cactus Project in Arizona. PFS drilling focused in the south of the Parks/Salyer deposit to upgrade near surface and low grade Inferred Mineral Resource Estimates (“MRE”) to the Indicated classification. Based on drill assays received, the Company expects a high mineral resource estimate conversion rate, as infill drilling continues to intercept consistent copper porphyry mineralization at both Parks/Salyer and the Cactus West deposits. Updating the mineral resource estimate model is now well-underway and an updated MRE for the Cactus Project is expected soon.\n \n 1\n \n The MRE update, targeting an upgrade of the Inferred mineral resource estimates into the Measured and Indicated classification, will feed into the PFS which is expected to be released in 2H 2025.

Drilling for the Definitive Feasibility Study (“DFS”) infill Indicated to Measured conversion drilling program, is now underway, with two drill rigs at Parks/Salyer. The planned p...
