Location and accuracy	Coordinates are for approximately the center of block of twenty-seven lode claims south of Dry Pass staked in 1961 and active through at least 1973 (U.S. Bureau of Mines, 1980).

Geologic setting

Geologic description Rocks in the area consist of a Cretaceous quartz monzonite pluton in contact with marble metamorphosed from Silurian Heceta Limestone and biotite-quartz-hornfels metamorphosed from Silurian graywacke and mudstone of the Bay of Pillars Formation (Brew, and others, 1984). The claims are probably related to this contact. Also see PE046 for specific deposits within this claim block.
