Geologic setting

Geologic description

By 1913, a short adit had been driven to explore an east-west trending shear zone that dips 25 S. (Chapin, 1914). A short drift was driven on the shear about 25 feet from the portal. The quartz-rich portion of the shear is 1 foot thick and contains iron-oxide-stained ribbon quartz in brecciated schist and clay gouge. No sulfides were seen in the shear zone underground however, quartz on the dumps is stained by antimony oxides. The total length of the adit is unknown because flooding made it inaccessible 30 feet from the portal (Chapin, 1914).
The prospect was examined in 1942 as a possible source of antimony but was not developed due to insufficient grade and thickness of antimony mineralization (Killeen and Mertie, 1951).
