At that time the only other mercury producing mine was in Almaden, Spain, so this area became known as New Almaden. New Almaden was the first mining community in California.

The mercury mined here was used in the extraction of gold from its ore. The New Almaden Mine was the biggest mercury-producing mine in the Americas.
