Pocket Gold in Gneiss
March 2004 by Edgar B. Heylmun, PhDMetamorphic rocks such as gneiss and schist are known for their pocket gold deposits. Such pockets may not be large enough for major mining operations, but may be very rewarding for individuals or small companies. Gold-bearing quartz veins may cut gneiss or schist, but often the veins parallel the bedding, or foliation. The origin of mineralized veins, which parallel the foliation, has been kicked around for years.
Picking the right spot to placer has to do with years of experience, and a little luck. The textbooks can tell you where it should be, but sometimes the rules just don’t seem to apply.

The Gold Hill (Clifton) mining district is located 162 miles, by road, west of Salt Lake City. All but the last 12 miles of road is paved. The settlement of Gold Hill (pop. 10) lies at an elevation of 5,321 feet in desert mountains, the highest of which, Dutch Mountain, is 7,800 feet above sea level. Ponderosa pine grows at the highest elevations, with a zone of pinyons and junipers below that.
