Reference information

Comments Grade of 0.1–0.3% Cu. Seltmann and Porter (2005) report age as Early Paleozoic (Caledonian - Ordovician to Silurian). Medium-size deposit (Nokleberg and others, 2006). Stockwork and vein deposit minerals occur in strong-altered host rock with sericite, silica and chlorite.
