|Location and accuracy||This occurrence is at an elevation of about 5,000 feet, 0.5 mile east-southeast of the top of hill 6575. The occurrence is in the SW1/4NW1/4 sec. 10, T. 28 N., R. 5 E., Seward Meridian. The location is accurate to within 1/4-mile. This is locality 52 of Csejtey and Miller (1978).|
Geologic descriptionThis occurrence consists of small amounts of chalcopyrite and pyrrhotite in quartz veinlets or as disseminations in highly iron-stained Triassic(?) metagabbro (Rose, 1967). A lode claim covers the prospect.
