This historic cinnabar mine is located at 704331mE, 4026720mN at 3560 feet and named on San Benito Mountain 7.5' quadrangle. This mine was discovered by Sylvester Tirado who owned it as part of his Esmeralda Quicksilver Mining Company holdings. Sylvester sold the mine to Alpine Quicksilver Mining Company in 1910. The mine remained up to the 1950´s and consisted of several shallow open cuts and more that 6000 feet of subsurface workings.

Historic photographs of the mine in operation, indicated several structures were present which may have housed the miners. The Alpine Mine was cleaned up and it surrounding habitat restored in 2001. The site restoration removed the retort structures a small rockcrusher, generator, ore hopper and grizzly. There is little evidence the mine remaining.
