Parks/Salyer Intersections Continue With Ongoing Drilling

CASA GRANDE, AZ - Arizona Sonoran Copper Company Inc. reported on 3 drill holes from its 105,000 ft (32,000 m) infill to indicated drilling program at Parks/Salyer (P/S), located ~1.3 mi (2 km) southwest of the Cactus Mine Project. Infill drilling continues to intersect thick high-grade mineralization which supports the currently modeled inferred Mineral Resource at P/S. Additionally, assay results from the final 4 exploration drill holes from Parks/Salyer’s western extents are also being reported. Results from these drill holes were included in the 2.9 B lb Inferred Mineral Resource Estimate (MRE).

Highlights include the infill drilling to 250 ft drill spacing, in support of an initial Preliminary Feasibility Study (PFS) within 11-17 months; ECP-098: 714.1 ft (217.7 m) @ 1.01% TCu, 0.90% Cu TSol, 0.024% Mo (enriched), including 298.0 ft (90.8 m) @ 1.39% TCu, 1.35% Cu TSol, 0.019% Mo; ECP-097: 746.2 ft (227.4 m) of continuous mineralization; 294.4 ft (89.7 m) @ 0.68% TCu, 0.65% Cu TSol, 0.018% Mo (oxide); 451.8 ft (137.7 m) @ 1.17% TCu, 1.10% Cu TSol, 0.026% Mo (enriched), including 82.6 ft (25.2 m) @ 2.30% TCu, 2.24% Cu TSol, 0.035% Mo; ECP-099: 552.0 ft (168.2 m) @ 1.10% TCu, 0.85% Cu TSol, 0.030% Mo (enriched), and 150.0 ft (45.7 m) @ 1.48% TCu, 1.29% Cu TSol, 0.033% Mo.

George Ogilvie, President and CEO. said, “We continue to move forward at our Cactus and Parks/Salyer projects concurrently, with the intent of issuing a combined Pre-feasibility Study in the next 11-17 months. The recently issued maiden mineral resource estimate for Parks/Salyer combined with the resource estimate at Cactus has now catapulted the combined projects to a size that would make it the 4th largest independent copper deposit in the U.S. with a total copper resource of 4.9 Billion lbs Inferred and 1.6 Billion lbs Indicated. At P/S the infill drilling to 250 ft centers is now well underway with all drilling and assaying expected to be completed in 2Q23. Further metallurgical columns on the P/S leachable mineralization is underway and are expected to run throughout 2023. Additionally, geotechnical and hydrological studies on P/S have now been initiated. At Cactus new metallurgical columns have begun, purposely designed for a future Bankable Feasibility Study.”
