Excelsior Commences Its 2012 Drilling Program at Gunnison
VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 29, 2012) - Excelsior Mining Corp. (TSX VENTURE:MIN)(OTCQX:EXMGF)(FRANKFURT:3XS) ("Excelsior") is pleased to announce that it has commenced its 2012 drilling program on the Gunnison Copper Project, located in southern Arizona. The program has begun with the utilization of both a diamond drill rig and a reverse circulation drill rig. The first series of drill holes are being completed in order to acquire additional metallurgical data. Subsequent drilling will focus on additional hydrological and geological data acquisition, with the goal of the entire 2012 program being the completion of a pre-feasibility study by year's end.
"We are excited to be back drilling on Gunnison again," stated Stephen Twyerould, President and CEO of Excelsior. "We have set an ambitious program for 2012 and, now that it is underway, we are looking forward to making significant progress in advancing the Gunnison project as quickly as possible."
The program is designed to advance the project geologically, hydrologically and metallurgically. The resultant data will be used to optimize well field design, leaching solution composition, as well as provide critical information for groundwater quality control and ultimately, project reclamation, all of which will be essential as the project moves forward in the permitting process.
Project Summary
The Gunnison Copper Project is located approximately 65 miles southeast of Tucson, AZ. The focus of the project is the North Star deposit, which currently has a total indicated mineral resource of 3.21 billion pounds of oxide copper (511 M tons at 0.31%) and an inferred mineral resource of 0.88 billion pounds of oxide copper (159 M tons at 0.28%). This oxide mineral resource has the potential to be mined using in-situ recovery methods. The Gunnison property also has the added benefit of being situated in a very remote location, near an existing mining operation.
Mineral resources that are not mineral reserves do not have demonstrated economic viability.
