Anderson Prospect, McKenzie Inlet, Prince of Wales Island, Ketchikan District, Prince of Wales-Outer Ketchikan Borough, Alaska, USA
Location: The only description of this prospect is by Brooks (1902), who located it 'about 100 yards west of the lower end of McKenzie Inlet.' For this record, it is about 0.5 mile northeast of the center of section 32, T. 75 S., R. 86 E.
Geology: The only published description of this prospect is by Brooks (1902). He describes it as a tunnel in chloritic schist that exposes a 3-foot-wide zone with chalcopyrite. The rocks in the area are greenstone, schist, phyllite, and minor marble of the Wales Group of Late Proterozoic and Cambrian age (Eberlein and others, 1983; Brew, 1996).
Workings: A short tunnel was driven before 1902.
Age: Unknown, other than that the prospect is in Late Proterozoic or Cambrian host rocks.
