Discovered in 1845, the New Almaden was the first mine in California and was producing large amounts of quicksilver before gold was discovered. It was named after the famous Almaden Mines in Spain. After a dispute over title, in 1864 the holdings became the Quicksilver Mining Company with headquarters in New York. A company town thrived with its own store, scrip, doctor and deputies. The Quicksilver Mining Company closed operations in 1912.
