Excelsior Mining Corp. (TSXV:MIN) commences the Gunnison Copper Project located within the copper porphyry belt in southeastern Arizona.
The press release is quoted as saying:
Samples from two recently drilled metallurgical holes have been shipped to Hazen Laboratory in Denver, Colorado for column leach testing. Preliminary results are expected in the middle of the second quarter of 2011. The column leach tests will greatly improve the current understanding of in-situ copper extraction on the Gunnison Copper Project. Excelsior’s metallurgical program will build upon prior work completed by Magma Copper Corporation (“Magma”). Magma drilled eight holes and completed several comprehensive metallurgical tests and hydrological studies. The Magma tests indicated acid consumption and copper recovery were favourable for in-situ mining on the Gunnison Project.
