Arizona Sonoran Reports Positive NutonTM Technologies Extraction Rates on Cactus Primary Sulphides

CASA GRANDE, Ariz, & TORONTO — Arizona Sonoran Copper Company Inc. (TSX:ASCU | OTCQX:ASCUF) (“ASCU” or the “Company”) an emerging US-based copper developer and near-term producer, today reports positive preliminary column leach metallurgical extraction rates using the Nuton^TM technologies as part of the Phase 1 testing program with Nuton LLC, a Rio Tinto venture. Primary sulphide extraction ranges from 61% to 82% based on 5 columns, including 2 early cycle columns returning 83% and 61%, 2 mid-cycle columns above 70% and 1 with lower extraction based on biotite content. Nuton is currently reassessing the additives for this low extraction column to address future biotite exposure, which accounts for approximately 1-2% of the Cactus West deposit in the primary zone. A total of 13 ongoing columns are approximately 75-150 days through their 300-day leach cycle and include samples from the sulphide, both primary and enriched (secondary sulphide) zones from both Cactus and Parks/Salyer deposits, as well as from the tailing facility, all of which are situated on wholly-owned private land in Pinal County, Arizona.
