Reference information

Comments Grade of 0.1–0.5% Cu, 0.0001–0.1% Mo. Probable reserves of 500,000 tonnes Cu. See also Ondor. Consists of a Cu sulfide zone with surface dimensions of 350 by 1100 m. The zone occurs in the SW and western part and along the contact of a granodiorite porphyry stock. Cu tonnage is calculated from Cu grade and ore tonnage.
