Adams Lode - Bismark
A W occurrence/mine located in sec. 16, T42N, R7W, NMM, above the east side of the north fork of Cement Creek, just north of Gladstone, on National Forest land. Owned by Thomas J. & Dorothy A. Mahon. Produced in 1899. MRDS database stated accuracy for this location is 10 meters.
Mineralization is a W deposit hosted in Pliocene andesite. The ore body strikes N10E and dips 85SE. Local rocks include intra-ash flow andesitic lavas.
Workings include unspecified surface openings. Underground openings are also apparently present (multiple adits ?).
Production was alleged to be substantial.
