Geologic setting

Geologic description

The Indian Mountain lode claims are at the contact between argillite and Tertiary granite (Kurtak and others, 1992). Quartz veins, with trace chalcopyrite, and pegmatite dikes cut the granite and extend into the argillite. Rock samples contain 1 part per million silver, 8 parts per million molybdenum, 6 parts per million bismuth, 20 parts per million lead, and 0.01 percent copper (Balen, 1990). At least some of these samples were quartz veins.
Geologic map unit (-149.592371284567, 62.8786165083657)
Mineral deposit model Polymetallic vein? (Cox and Singer, 1986; model 22c?)
Mineral deposit model number 22c?
Age of mineralization Probably related to Tertiary granite.

Production and reserves

Workings or exploration The Indian Mountain 1 to 6 claims were staked in 1962 and 1963. Rock samples collected by U.S. Bureau of Mines (Balen, 1990). At least some of these samples were quartz veins.
Indication of production None
