Arizona Sonoran Drilling Expands Primary Sulphide Zone Under and Around the Cactus West Pit

Arizona Sonoran reports new drill assay results from its infill and step-out drilling program below the previously untested extents of primary copper mineralization around the Cactus West pit, on the Cactus Project, in Arizona. Drilling builds upon the Company’s PEA drill database, extending the primary sulphide zones by upwards of 500 ft (152 m) below known mineralization

CASA GRANDE, Ariz. & TORONTO, September 16, 2024--(BUSINESS WIRE)--Arizona Sonoran Copper Company Inc. (TSX:ASCU | OTCQX:ASCUF) ("ASCU" or the "Company") reports new drill assay results from its infill and step-out drilling program below the previously untested extents of primary copper mineralization around the Cactus West pit, on the Cactus Project, in Arizona. Drilling builds upon the Company’s PEA drill database, extending the primary sulphide zones by upwards of 500 ft (152 m) below known mineralization (see FIGURES 1 – 10).

A total of 17 drill holes are reported herein for a total of 30,601 ft (9,387 m) of drilling, targeting the primary sulphides below the oxide and enriched zones at Cactus West. Step-out drilling continues with two drill rigs at Cactus West.

Drilling Highlights:

  • ECW-256: 2,119* ft (646 m) @ 0.40% CuT of continuous mineralization

    • 1,896.6 ft (578 m) @ 0.41% CuT, 0.005% Mo (primary)

  • ECW-258: 2,108 ft (643 m) @ 0.31% CuT of continuous mineralization

    • 2,001 ft (610 m) @ 0.31% CuT, 0.005% Mo (primary)

  • ECW-260: 1,901 ft (579 m) @ 0.33% CuT of continuous mineralization

    • 1,696 ft (517 m) @ 0.33% CuT, 0.009% Mo (primary)

  • ECW-266: 1,571 ft (479 m) @ 0.33% CuT of near continuous mineralization

    • 1,309 ft (399 m) @ 0.36% CuT, 0.009% Mo (primary)

  • ECW-252: 1,002 ft (305 m) @ 0.40% CuT of continuous mineralization

    • 352 ft (107 m) @ 0.44% CuT, 0.41% Cu TSol, 0.014% Mo (enriched)

    • 650 ft (198 m) @ 0.37% CuT, 0.017% Mo (primary)

NOTE: True widths are not known, * includes 1.9 ft of core loss

George Ogilvie, Arizona Sonoran President and CEO commented, "The drill program at Cactus West is showing significantly more primary sulphide mineralization below and outside of the existing resource pit shell. In conjunction with drilling at Cactus West our geological team is in the process of preparing for an infill drilling program at Parks/Salyer, predominantly focused on the southern claim block (MainSpring) to move into an indicated resource ahead of a new PFS next year. As the team’s focus is on advancing Cactus to the PFS level, additional workstreams are ongoing, including metallurgical column testing. New columns from the southern claim block for Parks/Salyer, are anticipated to start in 4Q24, once new metallurgical core has been made available."

Drilling Recap

The 2024 Cactus West infill and exploration drill program was designed to support the expansion of primary sulphide mineralization down to the basement fault below the oxide and enriched material, and laterally to extend mineralization in the south and southwest of the known resources.
