Geologic descriptionClark and others (1970 [OF 417]) report pyrite and chalcopyrite in greenstone at this site. The greenstone is probably metamorphosed Silurian or Ordovician basalt or andesite of the Descon Formation or Luck Creek Breccia (Eberlein and others, 1983; Brew, 1966). Maas and others (1992) collected two samples from a quartz vein in greenstone and black slate at about this location . The samples contained up to 124 parts per billion gold, 0.7 parts per million (ppm) silver, 133 ppm copper, and 882 ppm zinc.
