Pocket Gold in Gneiss
March 2004
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. 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.

In some places valuable ores can be found within the waste material of mine dumps, sorted ore piles, and detrital vein matter at the surface. Though many of these old mine sites can be an excellent source of gold, not all are created equal.

Picks & Pans: Prospecting at Mills Creek, Alaska
March 2000
I particularly enjoyed this little expedition. It is always nice to get out and spend time with my father, Bud Herschbach. He has taken a liking to Mills Creek and was anxious to return and look for more nuggets.
