The Mother Lode gold district of central California yielded millions of ounces of gold from placer and bedrock mines. Gold was produced from a region covering nearly 8000 square miles on the western margin of the Sierra Nevada Mountains from 1848 discoveries until the Second World War. Today, only a very small amount of gold is produced from the district, mostly by amateur prospectors.

Bedrock mining in the Mother Lode district was concentrated in the vicinity of the structural and lithologic contact between the Mariposa slate and the adjacent igneous and metamorphic rocks to the west. This steeply west-dipping zone is considered to be the ?mother lode? of gold for the region. Many of the early bedrock mines were developed in the black Mariposa slate, and typically followed quartz veins. The richest section of the Mother Lode was the stretch between Jackson and Plymouth in Amador County. During the late 1800?s, quartz mining was the major activity of the area, involving most of the population. Today, very few people are engaged in mining activities and the mining is seen as a colorful part of the past. Tourism and wine production are the money and lifestyle industries of the day. Bedrock mining is not sustainable today, on a large scale, even though high-grade gold deposits remain.
