CASA GRANDE, Ariz. & TORONTO -- Arizona Sonoran Copper Company Inc. (TSX:ASCU | OTCQX:ASCUF) (“ASCU” or the “Company”) today announces the advancement of an updated Mineral Resource model on the Parks/Salyer deposit, reflecting partial results from the completed first phase of the planned Feasibility Study infill drilling program (the “FS Drill Program”). The target of the updated model is to define Proven Mineral Reserves within the Pre-feasibility Study starter pit representing the first 2-2.5 years of planned copper cathode production. Based on returned drill assays and initial modelling to date, the Company expects modelling results to be consistent with those reflected in the Project’s currently defined Mineral Resource and Mineral Reserve estimates in the same southern zone of Parks/Salyer. The Mineral Resource model will be further updated with additional infill drill holes at Parks/Salyer following condemnation drilling planned for Q1 2026. See FIGURES 1-4, TABLE 1 and TABLE 2 for drilling maps, assay results and collar locations, respectively. Read More
