San Jose in Santa Clara County, California — The American West (Pacific Coastal)
New Almaden Quicksilver Mine
In 1845 Captain Andres Castillero, a Mexican soldier, diplomat and scholar, was sent to Alta California on a mission to Sutter’s Fort. The Mexican government wanted to buy out Sutter in an effort to keep out American settlers. When meetings between Castillero and Sutter failed, Castillero returned to Mission Santa Clara. It was there that he noticed the red paint in the artwork in the mission church and on the bodies of the Ohlones. Recognizing the red color as probably being that of cinnabar or silver, he proceeded to test the ore and discovered that it was indeed cinnabar. Indians took him to their source. He filed a denouncement on 3,000 vara of land for all sides of the cave mouth. This is the site of the richest mine in California and
Twenty-eight months later the discovery of gold sparked the great overland migration of people to California. Soon after arriving miners realized they needed quicksilver to amalgamate with gold. The community of New Almaden became an integral part of the gold rush because its quicksilver was readily available and inexpensive to ship to the Mother Lode. Wagons loaded with flasks traveled to the port of Alviso where the flasks were shipped to San Francisco for worldwide distribution. This local source of quicksilver made mining lucrative for the gold miner.
By 1865, life on Mine Hill was very wild and dangerous. Criminals, including Tiburico Vasquez, were hiding out, drinking was rampant, and shootings were common. In an effort to control the criminal element, mine manager Samuel F. Butterworth built a toll gate at the entrance to the Hacienda Mine works at the narrows of the canyon where Almaden Road and Almaden Way meet. The toll collector lived in the far apartment where he collected tolls and inspected wagons. The residents of Mine Hill were not allowed to bring in alcohol and guns. These residents were fined if they were caught with unacceptable goods.
Over the years, the three apartments
The story of New Almaden’s quicksilver and of the overland pioneers’ dreams of a better life will always be tied together as a rewarding and tragic human experience that helped settle the Santa Clara Valley, California and the American West.

Also see . . . The History of New Almaden. In 1845, a group of Ohlone Indians led Andrés Castillero, a captain in the Mexican military, to their source of cinnabar. The Ohlone used cinnabar in body paint to decorate themselves and also in trading. Castillero was also a mining engineer and recognized commercial uses for the cinnabar ore as a mercury agent. Castillero filed a mineral claim with the Mexican government in 1845 and began small-scale mining of the ore and quicksilver production. The Barron, Forbes Company obtained Castillero’s shares in 1846 and named the mines New Almaden for the famous Almaden quicksilver mines in Spain. Legal challenges plagued the land from the outset and in 1863 the Quicksilver Mining Company assumed ownership. (Submitted on April 6, 2011.)
