[{"type":"text","content":"CASA GRANDE, Ariz. & TORONTO / Apr 29, 2024 / Business Wire / Arizona Sonoran Copper Company Inc. (TSX:ASCU | OTCQX:ASCUF) (“ASCU” or the “Company”) reports the completion of its inferred drilling program on MainSpring, within the 100%-owned Cactus Project, Arizona. The inferred drilling program confirms a continuation of the thick enrichment blanket extending south and up dip from the Parks/Salyer deposit onto MainSpring, as well as the presence of enriched mineralization in MainSpring (see FIGURES 1-12). With the final receipt of assays, a MainSpring mineral resource model is now being generated for its inclusion to the integrated Nuton and Cactus Preliminary Economic Assessment (“PEA”) expected in Q3 2024. The completed program at 500 ft (152 m) centres between drill holes, extended mineralization over 2,500 ft x 3,000 ft (762 m x 914 m) within an interpreted horst block. The final 10 holes (17,916 ft | 5,460 m) from the now completed inferred program are reported herein. Two drills are now infill drilling at Cactus West within the primary sulphide zones, and one rig is focused on reducing drill spacings at MainSpring from inferred to indicated for use in an updated Prefeasibility Study which is scheduled to initiate later this year. Highlights: - In support of a single mineral resource model, the drill program successfully connected the high grade thick enriched Parks/Salyer mineralization and the shallow lower grade MainSpring mineralization - *ECM-218: 1,206 ft (368 m) @ 0.56% CuT of continuous mineralization *Incl 290 ft (88 m) @ 0.95% CuT, 0.56% Cu TSol, 0.088% Mo (enriched) And 676 ft (206 m) @ 0.46% CuT, 0.012% Mo (primary) - ECM-215: 1,430 ft (436 m) @ 0.32% CuT of continuous mineralization Incl 388 ft (118 m) @ 0.50% CuT, 0.34% Cu TSol, 0.012% Mo (enriched) And 662 ft (202 m) @ 0.26% CuT, 0.003% Mo (primary) - ECM-222: 965 ft (294 m) @ 0.42% CuT of continuous mineralization Incl 127 ft (39 m) @ 1.12% CuT, 0.88% Cu TSol, 0.025% Mo (enriched) And 837 ft (255 m) @ 0.31% CuT, 0.005% Mo (primary) - ECM-213: 25 ft (8 m) @ 1.18% CuT, 1.13% Cu TSol, 0.003% Mo (oxide), from 137 ft (42 m) NOTE: True widths are not known; * Interval includes 2.2 ft (0.67 m) of missing core George Ogilvie, Arizona Sonoran President and CEO commented, “Drilling has performed extremely well for the Company, outlining a new zone of copper miner...
