Geologic setting

Geologic description

Prior to WW I, several lode claims were explored by many openings, including a 60-foot adit and a 50-foot adit (Smith, 1913 [B 525, p. 208]). A small, well-defined quartz vein was exposed in one adit, where all the gold appeared to be contained within the vein. The bedrock at this prospect is Fairbanks Schist, which is composed of quartz-muscovite schist, quartzite, and chlorite-quartz schist (Newberry and others, 1996).
