Comments on the geologic information

  • Geologic Description = This deposit is associated with skarns in medium-grade metamorphic rocks, irregular quartz veins or segregations containing galena and sphalerite. The deposit crops out in an area of at least 10 x 40 feet. The deposit may be related to a small granite pluton nearby. Samples from surface trenching contained 2800 ppm Ag and 5000 ppm Zn (Garland and others, 1975, DGGS OFR 67). Other analysis of massive galena indicates up to 1000 ppm Ag and 700 ppm Sb (Grybeck and Nelson, 1981). The deposit was staked in about 1976; work aparently was limited to surface trenching.
