Exploration Drilling Intersects Near Surface Mineralization South Of Parks/Salyer

CASA GRANDE, AZ - Arizona Sonoran Copper Company Inc. reported 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 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. 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), includes 115 ft (35.1 m) @ 0.58% CuT, 0.56% Cu TSol, and 50 ft (15.2 m) @ 0.49% CuT, 0.48% Cu TSol. Partial hole; assays related to the primary sulphides are pending. \

ECM-187: 716 ft (218 m) @ 0.28% CuT of continuous mineralization from 144.3 ft (44 m) depth; 303.7 ft (92.6 m) @ 0.35% CuT, 0.32% Cu TSol from 144 ft (44 m) depth (oxide), including 11.7 ft (3.6 m) @ 3.39% CuT, 3.29% Cu TSol, and 20 ft (6.1 m) @ 1.01% CuT, 1.00% Cu TSol. 124.9 ft (38.1 m) @ 0.34% CuT, 0.33% Cu TSol (enriched), including 34 ft (10.4 m) @ 0.86% CuT, 0.84% Cu TSol. ECM-186: 570 ft (173.7 m) @ 0.19 % CuT of near continuous mineralization from 138 ft (42 m) depth. ECM-191: 317.1 ft (96.7 m) @ 0.23% CuT, 0.23% Cu TSol from 370.4 ft (113 m) depth (enriched), including 126.6 ft (38.6 m) @ 0.35% CuT, 0.34% Cu TSol.

George Ogilvie, President and CEO, said, “Assay results coming from the MainSpring property reinforces the strength of our Cactus porphyry copper system and the significance of the Parks/Salyer deposit to the overall Cactus Project. The property continues to demonstrate growth opportunities beside an already significant copper deposit within a world class jurisdiction, on a property with a clear path to development. While these results are the first three and a half holes from the 10-hole drilling program, we are excited about MainSpring’s near surface potential next to the deeper high-grade Parks/Salyer deposit. We look forward to planning the expanded drill program for 2024 with a view to continue delivering value to the ASCU shareholders.”
