Exploratory Drilling Begins At The Mainstay Property At Parks/Salyer South

CASA GRANDE, AZ - Arizona Sonoran Copper Company Inc. drill assays from 5 holes at Cactus East and 4 from Parks/Salyer (18,467 ft | 5,629 m). Drilling at 125 ft (38 m) drill spacings demonstrating the continuity and thicknesses of mineralization within the proposed Cactus East and Parks/Salyer high grade underground oxide and enriched mineralized zones. Additionally, the Company has begun exploratory drilling at the MainSpring property (Parks/Salyer South), with five holes now complete. The program consists of up to 10 drill holes, targeting shallow mineralization 1,500 ft (~450 m) south of the Parks/Salyer deposit. The Parks/Salyer deposit contains 143.9 Mtons @ 1.009% Cu M&I and 48.4 Mtons @ 0.967% Cu Inferred (PR October 16, 2023) and remains open to the south onto the MainSpring property.

George Ogilvie, President and CEO said, “At Cactus, the team continues to derisk the asset and drive project development forward on all fronts while concurrently reducing drill spacing to support Feasibility-level requirements. In addition, one drill is now focused on the extension of Parks/Salyer mineralization to the south. Earlier this year, we strategically optioned to acquire the MainSpring (Parks/Salyer South) Property. The option agreement gains access to the southern extension of our +1% Cu Parks/Salyer deposit, where our goal is to not only grow the resource but also confirm near surface mineralization as drilling moves south, as seen by historical drilling results.”

A total of 106,815.9 ft (32,557.5 m) over 51 holes, from the Cactus East and Parks/Salyer infill-to-measured drilling programs have been reported this year. The geological team continues to work toward completing the drilling needed for measured resources for the Definitive Feasibility Study planned for 2024. Drilling continues ASCU’s focus on defining the high-grade cores of the Cactus East and Parks/Salyer orebodies with encouraging and consistent intervals of mineralization. Holes ECE-143 and ECE-146 support the continuity of width and grade indicated by the earlier 250 ft (76 m) infill-to-indicated drill program, especially the high-grade oxide cap that overlies the enrichment blanket that forms the heart of the orebody. Holes ECE-182 and ECE-183 were drilled at the extreme NE end of the Cactus East to extend thick oxide mineralization encountered earlier in the Indicated Drilling Program toward the bounding East Fault. These holes did encounter enriched and higher-grade primary mineralization below the fault, but the thickness of mineralization was terminated by the fault.
