Regarding Treasure Mine. Amador County’s Gold Mine Trail was established as part of the Amador County Sesquicentennial celebration in 2004. It is a 15 mile driving tour of some of the county’s 300+ gold mines. There are 18 stops on the tour of which Treasure Mine is the sixteenth.
From the Gold Mine Trail booklet: “After the placer gold rush of 1848-50, miners began to dig into the earth and rock to uncover gold imprisoned in quartz rocks’ deep veins. The largest vein was the Mother Lode between Yosemite (Oakhurst) and Georgetown in El Dorado County. The 20-mile stretch from the Mokelumne River to the Cosumnes River was the richest, producing some $160 million in gold between 1851 and 1842 (current value $5 billion).

claim and the Spring Hill were soon followed by many others: Lincoln, South Spring Hill, Keystone, Original Amador, and Eureka.
By the 1870s-80s Amador County was working 300+ mines. There were some tunnels, but later incline and vertical shafts reached down a mile into the ground. The Kennedy and Argonaut were close to 6,000’ deep. Headframes crowned shafts and stamp mills processed and crushed the ore. Some mines were worked by their founders but most were sold time and again and were improved or went bust. Large American and foreign companies traded in stock and ran the mines from afar.
Workers came from all over the world to look and work for gold. Most were from Europe: Italy, Yugoslavia, and Cornwall. Many stayed on the settle towns, marry and, raise families. Some mines vanished over the years; others still exist. Of the 300-400 mines, only eight headframes still stand, but may foundations, shafts and surface works remain.”
