Bald Mountain Mine located in Baker County, OR containing 68.52+/- acres in a group of patented mining claims commonly known as the BALD MOUNTAIN CONSOLIDATED QUARTZ MINING CLAIM consisting of the Bald Mountain, Saginaw, Albine, and Three Star lode mining claims. The project has a rich history of gold and silver mining beginning in the 1800's. The gold-silver vein system is located in the Elkhorn Mountains within the Blue Mountain Range of northeastern Oregon. There is good infrastructure including roads, cell coverage, power grid, railways, etc. The mineralization occurs in northeast-striking, steeply dipping fissure veins, hosted by the Elkhorn Ridge argillite within several miles of the Bald Mountain batholith. The vein material consists of gouge, quartz argillite breccia and quartz veined argillite. Mineralization consists of visible gold and electrum, tetrahedrite (freibergite), pyrargyrite, pyrite, and other minor silver minerals. A major underground and surface exploration drilling program with significant expenditures was carried out on the Ibex-Bald Mountain vein systems over a period of 9 years from 1980 to 1989. Mineralogical studies, metallurgical tests, mine feasibility studies, and other engineering projects have been completed. Gold and silver recoveries are in excess of 90% using standard flotation techniques and moderate grinds. CIP cyanide leaching of the concentrate resulted in overall recoveries of about 85% gold and 64% silver. Improvements made since 2011: .Upper and Lower settling ponds repaired and cleaned .Drainage culverts installed .Surface drainage channels repaired and cleaned .Re-timbered both upper and lower portals .Repaired track, compressed air and water pipes .Power supplied by 10KW generator .Air tubes and fans installed in lower level .Access opened to all drill stations underground.
