Description
The New Almaden Mine Collection (Bulmore) contains documents dating from 1850 to 1976. The materials, measuring 15.5 linear feet are housed in 18 boxes and are arranged in 8 series: Administrative, Miners and Miners' Fund, Ledgers, Printed Materials, Research Files and Clippings, Ephemera, Maps and Drawings, and Photographs. The bulk of the documents cover the period of the late 1800's.
Background
In 1845, Captain Andres Castillero of the Mexican Army was sent on a routine scouting patrol through what is now northern California, then part of Mexican territory. As an amateur geologist, Castillero recognized the possibility that the rolling hills held vast mineral deposits. During a visit to local Ohlone indians, his suspicions were confirmed. The Ohlones told him of the red rock they used to make paint, and of the cave where the walls were solid deposits of this red rock. A trip to the cave left Castillero amazed; the red rock was cinnabar, high grade mercury ore. He quickly filed a claim with the most suitable local authority, a justice of the peace, and received mineral rights to excavate the mine site. The rights were divided among five principal holders, including Castillero, his guide, and the Ohlones who led him to the mine.
