Shale Wikipedia

Shale is a fine-grained, clastic sedimentary rock, composed of mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by breaks along thin laminae or parallel layering or bedding less than one centimeter in thickness, called fissility. It is the most common sedimentary rock.

» The Science of Bedrock Gold

The gold is found not only in the bedrock, but in gravels as much as two feet above the bedrock. In the original pay-streak on Wade Creek, gold is found as deep as 1 1/2 feet into the bedrock. The origin of the gold is supposed to have been from the quartz stringers in the schists. The gold becomes black toward the head of Wade Creek.
