Arizona Sonoran Copper Company has announced progress on its Mineral Resource model for the Parks/Salyer deposit, incorporating results from the initial phase of the Feasibility Study (FS) drill program. This updated model targets the definition of Proven Mineral Reserves for the first 2-2.5 years of production.

Approximately 70% of the FS Drill Program, totaling 92,000 ft, has been completed, with results aligning with expectations. The focus will shift to condemnation drilling, with further infill drilling planned for Q1 2026 to enhance the model. Geotechnical and hydrogeological drilling is also in progress as per recommendations from the Prefeasibility Study.
