The Coppercorp Mine operated between 1965-1972 producing roughly 1 million tons of ore at mine recovered grade of 1.16% which is equal to 23.8 million pounds of copper. The mine shut down due to a decline in copper prices. Following closure, the property was alienated from mining and exploration for 30 years.
This zone contains original mine workings. Superior Copper believes potential exists below the 3rd level to discover more resources. A deep diamond drill hole tested the target in 2011 but intersected a thick conglomerate unit where the structure pinches to narrow widths.

This zone was trenched and sampled in 2010 from which assays returned up to 51.8% copper. Diamond Drilling in 2011 intersected high grade vein breccia but mineralization was discontinuous. Follow up drill will test the continuity of grade and width to the north where the structure may be buried.
