|Location and accuracy||This occurrence is at an elevation of about 3,400 feet, 1/2 mile west of the north end of lake 2710. The occurrence is in the SE1/4 sec. 32, T. 29 N., R. 3 E., Seward Meridian. The location is accurate to within 1/4 mile. This is locality 43 of Csejtey and Miller (1978).|
Geologic descriptionThis occurrence consists of pyrite-bearing quartz veinlets that cut pyritic, malachite-stained, alteration zones in mafic metavolcanic rocks. Samples collected by the U.S. Geological Survey contain up to 1,000 parts per million copper, 10 parts per million molybdenum, and 0.05 part per million gold (Miller and others, 1978).
