At the Gold Quarry open-pit mine, a massive electric shovel scoops 40 tons of earth in a single bite and dumps it into a 325,000-pound truck the size of a two-story house.
In 1997, I had been working a hard rock claim in Lone Valley, Nevada with two partners. It was a small seam about one to two inches wide that had free gold up to 9 ounces per ton.
Metamorphic 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.

The origin of mineralized veins, which parallel the foliation, has been kicked around for years.
