Location of the San Dimas Project
The San Dimas gold-silver mine is located on the border of the States of Sinaloa and Durango, some 125 kilometres northeast of Mazatlan in central west Mexico.
 
History of the San Dimas Project
The San Dimas deposit was first mined in 1757 and was continuously worked by the Spanish until 1810, at the start of the Mexican War of Independence.
 
Geology of the San Dimas Project
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.
