About the El Tigre Historic Mine District

Silver Tiger Metals Inc. is a Canadian company whose management has more than 25 years’ experience discovering, financing and building large epithermal silver projects in Mexico. Silver Tiger’s 100% owned 28,414 hectare Historic El Tigre Mining District is located in Sonora, Mexico. Principled environmental, social and governance practices are core priorities at Silver Tiger.

The El Tigre historic mine district is located in Sonora, Mexico and lies at the northern end of the Sierra Madre silver and gold belt which hosts many epithermal silver and gold deposits, including Dolores, Santa Elena and Las 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 production coming from 3 parallel veins the El Tigre Vein, the Seitz Kelley Vein and the Sooy Vein.  Underground mining on the middle El Tigre Vein extended 1,450 metres along strike and was mined on 14 levels to a depth of approximately 450 metres.  The Seitz Kelley Vein was mined along strike for 1 kilometre to a depth of approximately 200 metres.  The Sooy Vein was only mined along strike for 250 metres to a depth of approximately 150 metres.  Mining abruptly stopped on all 3 of these veins when the price of silver collapsed to less than 20¢ per ounce with the onset of the Great Depression.  By the time the mine closed in 1930, 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.
