History of the El Tigre Mine District & Geological Journal Articles

The El Tigre Property lies at the northern end of the Sierra Madre gold belt which hosts many epithermal gold and silver deposits including Dolores, Santa Elena and Chispas at the northern end.  In 1896, gold was first discovered on the property in the Gold Hill area and mining started with the Brown Shaft in 1903.  The focus soon changed to mining high-grade silver veins in the area with much of the production coming from the El Tigre vein.  Underground mining on the El Tigre vein extended 1,450 meters along strike and mined on 14 levels to a depth of 450 meters.   By the time the mine closed in 1938, it is reported to have produced a total of 353,000 ounces of gold and 67.4 million ounces of silver from 1.87 million tons (Craig, 2012). The average grade mined during this period was over 2 kilograms silver equivalent per ton.
