The Butte is a gold, lead, and silver mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Comments
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Maas and others (1995, p. 254) suggest that the age of the Brigadier deposit is Eocene, based on similarities in mineralogy, structural setting, and hostrock, to isotopically dated Eocene deposits in the Hyder district (see, for example, BC086). If so, the age of the deposit is contemporaneous with emplacement of the Hyder Quartz Monzonite.
Comment (Geology): Geologic Description = The country rock in the area of this prospect is the Triassic Texas Creek Granodiorite, which underlies and locally intrudes pelitic metasedimentary and subordinate andesitic (greenstone) metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group; and the Eocene Hyder Quartz Monzonite, which intrudes the Hazelton and Texas Creek rocks (Smith, 1977, Koch, 1996). The deposit (Buddington, 1929, p. 81) consists of quartz fissure veins in granodiorite that contain galena and pyrite. There are two main veins, each 10 inches to 3 feet thick, that have been traced in outcrop for 400-500 feet. Early assays of two samples showed 11.4-14.1% Pb, and 0.24-0.6 oz Au and 10.2-20.6 oz Ag per ton. Byers and Sainsbury (1956, p. 140) report that the veins also contain rare grains of scheelite. Maas and others (1995, p. 254) suggest that the age of the Brigadier deposit is Eocene, based on similarities in mineralogy, structural setting, and hostrock, to isotopically dated Eocene deposits in the Hyder district (see, for example, BC086). If so, the age of the deposit is contemporaneous with emplacement of the Hyder Quartz Monzonite.
Comment (Workings): Workings / Exploration = Prospect was explored by opencuts and a 25-foot shaft, probably in the early 1920's. Early assays of two samples of sulfide-bearing quartz veins showed 11.4-14.1% Pb, and 0.24-0.6 oz Au and 10.2-20.6 oz Ag per ton.
Comment (Deposit): Model Name = Polymetallic veins
Comment (Deposit): Other Comments = The prospect probably was originally staked in the early 1920's. Early reports describing the Brigadier property also refer to the Butte (Buddington, 1929, p. 81) and Hyder Butte (Cobb, 1978, p. 13, 92) claims.
Comment (Reference): Primary Reference = Buddington, 1929
