Lode Gold Mines of the Alleghany - Downieville Area, Sierra County, California. - Probably one of the best known areas for Gold in all of California, the belt between Alleghany and Downieville has produced and is still producing vast amounts of gold from its hard rock formations. While a lot of placer gold has been taken out as well, it is the hard rock mines and beautiful crystalline gold in Quartz that this area is known for. This publication is also a little know document that is very hard to find as it is buried in another publication. We dug it out and put it back in print. By Sylvanite Publishing.
