[{"type":"text","content":"CASA GRANDE, Ariz. & TORONTO / May 02, 2022 / Business Wire / Arizona Sonoran Copper Company Inc. (TSX:ASCU | OTCQX:ASCUF) (“ASCU” or the “Company”), an emerging US-based copper developer and near-term producer, announces results from 25 drill holes (30,926 ft | 9,426 m), from its now complete Cactus Prefeasibility Study (“PFS”) infill drilling program (see FIGURES & PHOTOS 1 – 8 and TABLE 1 below). The PFS drilling program tightened the drill spacing within the entire integrated Preliminary Economic Assessment (“PEA”) mine plan, including Cactus East and West and the Stockpile, with the intent of upgrading the Inferred mineral resources to Indicated mineral resources. As a result of tighter drill spacing, data shows an improved resolution of lithological, structural, and mineral zonation controls. Additionally, drilling to support further metallurgical and geotechnical test work was undertaken. The PFS is expected to be complete by late summer 2022 and will include an updated mineral resource estimate. Drilling Highlights (please see TABLE 1 below for full set of drilling results) Drilling improved definition of various host lithologies that potentially affect acid consumption in the heap leaching process. The majority of mineralization is hosted in granite and monzonite porphyry which to date has indicated low acid consumption characteristics ECE-053 200.9 ft. of 1.28% TCu, 0.91% TSol (Enriched – underground) ECE-051 90 ft of 1.56% TCu, 1.45% TSol (Enriched – underground); incl. 40 ft of 2.53% TCu, 2.38% TSol ECW-032 465.7 ft of 0.27% TCu, 0.24% TSol (Oxides – open pit); incl. 104.0 ft of 0.40% TSol ECW-056 462.9 ft of 0.31%TCu, 0.25% TSol (Oxides – open pit) ECW-036 617.0 ft of 0.21% TCu, 0.19% TSol (Oxides – open pit); and 351.0 ft @ 0.37% CuT (Primary) Infill drilling performed within expectations with no significant changes to the global interpretations supporting the previously reported resource model George Ogilvie, Arizona Sonoran President and CEO stated, “These positive drilling results support the conversion of mineral resources to the indicated category ahead of our PFS in Q3 as it pertains to the low-grade, bulk tonnage open pit operation at Cactus West and higher-grade underground Cactus East. We expect the drilling will convert a substantial amount of the leachable copper to a maiden probable reserve, whi...
