Announcement summary: M3 Engineering & Technology Corporation (M3) was commissioned by Excelsior Mining Corp. (“Excelsior”) to prepare an updated Prefeasibility Study (PFS) in accordance with the Canadian National Instrument 43-101 (“NI 43-101”) standards for reporting mineral properties, for the Gunnison Copper Project (the “Gunnison Project” or the “Project”) in Cochise County, Arizona, USA. The Project utilizes in-situ recovery (ISR) methods to leach copper from a buried copper oxide deposit and extract the copper by conventional solvent extraction-electrowinning (SX-EW) technology. The ISR process involves injecting leach solutions acidified with sulfuric acid into the oxidized mineralization to get soluble copper into solution. Recovery wells pump the copper-bearing pregnant leach solution (PLS) to the surface for copper recovery by SX-EW into salable copper cathodes.
