The San Dimas deposit occurs in the central part of the Sierra Madre Occidental volcanic pile which contains rocks reflecting two separate periods of magmatism which were active between 100-45 million years ago and 32-23 million years ago. The veins are contained within rhyolitic, andesitic and granodioritic rocks of the older magmatic episode.
