Comments on the geologic information

  • Geologic Description = The country rocks near the White Knight prospect are Silurian or Ordovician extrusive, intrusive, and marine sedimentary rocks that are intruded by a Silurian trondhjemite stock (Berg, 1973; Berg and others, 1988). The Silurian or Ordovician rocks have been regionally metamorphosed to greenschist grade.? Wright and Wright (1908, p. 140) describe the deposit as small masses of chalcopyrite, pyrite, and pyrrhotite in greenstone country rock. In the early 1900s, prospectors staked two claims on the property, which they probably explored mainly for gold.
