Casa Grande, AZ and Toronto, ON, November 20, 2023 – Arizona Sonoran Copper Company Inc. (TSX:ASCU | OTCQX:ASCUF) (“ASCU” or the “Company”), reports that exploration drilling at the MainSpring property intersected near surface copper mineralization from 4 drill holes. The southern-most MainSpring drill hole, ECM-186, was collared 2,500 ft (762 m) south of the Parks/Salyer deposit (see FIGURES 1-9) and intersected shallow oxide mineralization at a depth of 138 ft (42 m) from surface. In comparison, Parks/Salyer mineralization begins at approximately 550 ft (176 m) at its shallowest, over a footprint of 2,000 ft by 2,500 ft. The MainSpring property is situated contiguous to the Parks/Salyer Property and within the, privately held by ASCU, Cactus Project in Arizona.
Eight of 10 drill holes are now complete within the MainSpring exploration program announced October 30, 2023. Current drilling is testing the near surface extension of mineralization south of the Parks/Salyer deposit across the MainSpring property. Based on early drilling results, a comprehensive 2024 exploration program is being planned to discover the extents of shallow mineralization to the south and then connect the shallow mineralization to the thick high-grade zones at Parks/Salyer in the north.
Identified shallow mineralization at least 2,500 ft (762 m) south of the Parks/Salyer deposit
Near surface mineralization begins at ~138 ft (42 m) in 3 of the southern-most drill holes, compared to ~550 ft (166 m) or greater in the Parks/Salyer deposit
ECM-190: 433 ft (132 m) @ 0.34% CuT, 0.31% Cu TSol from 336 ft (102 m) depth (enriched)
Incl 115 ft (35.1 m) @ 0.58% CuT, 0.56% Cu TSol
