In processing gold, silver and other valuable ores, the minerals containing the values, such as metallic gold, silver-bearing sulfides or other minerals, must be freed from the surrounding host rock before those valuable minerals can be captured.
Most gold-bearing veins in this region are controlled by fractures associated with the Melones Fault, a late Cretaceous structure that is 108 to 127 million years old.
