Mining was suspended in 1981 due to low copper prices. At the conclusion of mining, a trackless development decline had been extended to a depth of 270 m below surface (to an elevation of 1,400 m a.s.l.) and 3,935 m of drilling had been completed in 76 underground holes. Dekalb calculated a resource around the mine workings after mining terminated.
