MainSpring Drilling Intersects Near Surface Mineralization

MainSpring Drilling Intersects Near Surface Mineralization

CASA GRANDE, AZ – Arizona Sonoran Copper Company Inc. (ASCU) reported on the exploration program at the MainSpring property, situated within the Cactus copper project in Arizona. A total of 7 of 11 ASCU drilled holes completed last year and 22 legacy holes from the previous option holder are reported here and indicate mineralization from the Parks/Salyer deposit nears surface as it extends south. Future drilling will test the open pit potential of MainSpring with the intent of updating the Cactus Mineral Resource Estimate post-Prefeasibility Study (PFS).

ECM-194: 1,053 ft (321 m) @ 0.20% CuT, of mineralization from 147 ft (45 m) depth; 48 ft (15 m) @ 0.35% CuT, 0.25% Cu TSol, 0.001% Mo (oxide); and 471 ft (144 m) @ 0.3% CuT, 0.29% Cu TSol, 0.001% Mo (enriched).

ECM-195: 503 ft (153 m) @ 0.27% CuT of mineralization from 145 ft (44 m) depth; 41 ft (12.5 m) @ 0.63% CuT, 0.59% Cu TSol from 145 ft (44 m) depth (enriched); 208 ft (63 m) @ 0.44% CuT, 0.40% Cu TSol, 0.001% Mo (enriched) from 440 ft (134 m); and 41 ft (12.5 m) @ 0.63% CuT, 0.59% Cu TSol, from 145 ft (41 m) depth.

ESC-010: 1,027 ft (313 m) @ 0.30% CuT of continuous mineralization; 170 ft (52 m) @ 0.59% CuT, 0.46% Cu TSol, 0.017% Mo (enriched); and 857 ft (261 m) @ 0.24% CuT, 0.009% Mo (primary).

ESC-047: 216 ft (66 m) @ 0.60% CuT, 0.51% Cu TSol, 0.011% Mo (enriched). ESC-046: 175 ft (53 m) @ 0.68% CuT, 0.65% Cu TSol, 0.004% Mo (enriched). ESC-030: 249 ft (76 m) @ 0.41% CuT, 0.31% Cu TSol, 0.006% Mo (oxide). ?George Ogilvie, President and CEO, said, “The MainSpring Property shows early signs of promise with continuous mineralization starting from near surface, that may have the potential for being open pittable. Given we only started drilling MainSpring late in 2023, it will not feature in our soon to be released PFS. However, with continued drilling in 1H24, it has the potential to be included in future technical studies that may further enhance the production profile and economics of the Project.

The Cactus property continues to show itself as a lower risk copper project with few barriers to entry and low discovery costs. We are showing discovery costs per pound at Cactus of less than two cents per pound, indicating that we should continue our exploration programs, while concurrently developing our main project. Our high-performing team continues to deliver excellent results and we expect this to continue with our 2024 work program which is currently being finalized and will be announced to the market shortly.”
