Location and accuracy This prospect is on the third small, east tributary upstream from the mouth of Iron Creek (SO127). This location is locality 4 of Cobb (1972, MF 445; 1978, OF 78-181). The original reference to this prospect is Cathcart (1922, p. 217) who notes that it is about a mile above Bertha Creek. It is very approximately located.

Geologic setting

Geologic description

A 3-foot-wide zone of silicified marble contains copper sulfide and some malachite stain (Cathcart, 1922). A nearby calcite vein is cut by quartz veinlets and pyrite is present in both. Bedrock is part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986). Also see other copper prospects in the Iron Creek area such as SO124 and SO125.
