Comments
Comment (Workings): Workings / Exploration = The workings in 1932 consisted of two adits, two shafts, a pit, and four trenches, all of which were caved by the 1950's (Byers, 1957).
Comment (Geology): Geologic Description = The Columbia tungsten deposit consists of quartz-mica schist cut by quartz-scheelite stringers, under a hanging wall of porphyritic granite (Byers, 1957; Mertie, 1917). Workings in 1932 consisted of two adits, two shafts, a pit, and four trenches, all of which were caved by the 1950's (Byers, 1957).
Comment (Reference): Primary Reference = Byers, 1957
Comment (Deposit): Model Name = W skarn deposit (Cox and Singer, 1986; model 14a)
Comment (Exploration): Status = Inactive
