Comments
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = Polymetallic veins
Comment (Deposit): Other Comments = Property originally staked in mid-1920's. Claims lie mainly on the Canadian side of the International Boundary.
Comment (Reference): Primary Reference = Buddington, 1929
Comment (Geology): Geologic Description = The country rock in the area of this occurrence is Triassic Texas Creek Granodiorite, which regionally underlies and locally intrudes pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group (Smith, 1977; Koch, 1996).? the deposit (Buddington, 1929, p. 92-93) consists of a quartz fissure vein, probably in granodiorite. The vein is as much as a foot thick (average is 6 inches thick) and contains disseminated chalcopyrite and local shoots of pyrite and galena; plates of barite are common.
