Orebody formirregular
Ore controlGold mineralization was formed along the edge of an Eocene age volcanic filled graben or possible caldera margin. The graben contact fault is a "feeder fault", containing high-grade gold (30 feet of 0.260 opt) at the shale-dolomite graben fault contact. The strike extension of this fault, and the alteration associated with it, is at least six miles long.
Associated rockBald Mountain Stock and associated intrusive rocks
StructureBlack Metals Fault zone and other steeply-dipping fault zones.
