Mining district

District name Colville

Comments on the workings information

  • Workings / Exploration = A high grade sample contains up to 39.9% Pb, 23.94% Zn, 875 ppm Cu and 53.6 oz per ton Ag; stream sediment samples collected in this area by the U.S. Bureau of Mines are also anomalous in these elements (Meyer and Kurtak, 1992, p. 46-61).
