The Shafter Silver Mine, operated by Aurcana Corporation (Canada) was started in 2008, to recover an estimated 47 million ounces of silver (8-10 oz./ton of ore) remaining in a northeast (down-dip) extension of the old Presidio mine workings (abandoned in 1942). Aurcana purchased the Presidio Mine and surrounding property in 2008. The silver mineralization in the Shafter deposit is hosted by the Mina Grande formation (limestone), in a carbonate replacement deposit, along a northeasterly trend extending about 3-miles.
In early 2009, a 1,052 foot, 7-foot diameter production shaft serviced by an 80 ton/hour hoist, and 5,100 feet of underground development was built. The plan was to recover 3.2 million ounces of silver per year at startup. An underground crusher was planned, with ore to be processed in above-ground leach tanks. After about two years of production, due to equipment problems, low silver values in the area explored, and falling silver prices, the mine was shut down in November, 2013.
