Geologic setting

Geologic description

There is an old adit less than 20 feet long at this prospect but there is no record of who did the work or when it was done, nor is there any record of production (Herreid and others, 1978; Maas and others, 1991, 1995). The rocks in the area consist of quartz-sericite-chlorite schists, pyroclastic breccia, and metabasite. Locally there are quartz veins parallel to the layering. Herreid and others (1978) collected a sample of pyrite-quartz-sericite schist that contained 20 parts per million (ppm) gold and 90 ppm lead. A table in their report also lists niobium, but they do not give a value for it in their description of the sample nor are significant amounts of niobium likely in this geologic environment. Maas and others (1991) collected 8 samples; their highest value was 210 parts per billion gold and 1.6 ppm silver.
