Land Status

Land ownership: BLM Administrative Area
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Structure

Type: R
Description: The Bald Mountain district is located in an area of thinned crust along the eastern side of the Late Proterozoic rift that split the North American craton. It is also in the west-central portion of the Late Devonian-Early Mississippian Antler foreland basin, and near the eastern edge of deformation related to the late Paleozoic Humboldt orogeny To the west of the Bald Mountain district, geologic interpretations are dominated by recognition of Paleozoic deformation, whereas to the east, interpretations emphasize Mesozoic contraction and plutonism and Tertiary extension.

Type: L
Description: At Galaxy, the dominant structure controls are

Comments

Comment (Commodity): Ore Materials: gold

Comment (Development): Development in the northeastern part of the district began in 1987. The ARM Joint Venture (Amselco with, at dif- ferent times, Occidental Petroleum, Nerco, Kennecott) began relinquishing claim groups north of Alligator Ridge Mine that were originally staked as part of an agreement with Lyle Campbell. Campbell retained and maintained the claim groups and, in November 1987, leased the Casino-Winrock area of claims to the USMX-Pegasus Joint Venture who began mining the deposit in 1991. Mining commenced in July, 1991 and was completed in 1992. Haul distance was 1.3 miles and strip ratio was 0.93:1. In 2006, Barrick Gold Corp. acquired the Galaxy Mine property through its acquisition of Placer Dome U. S., Inc.

Comment (Identification): The Galaxy Mine deposit is encompassed by Placer Dome?s Mooney Basin mine area.
