Location and accuracy The approximate location of the White Knight prospect is near sea level on the northwest coast of Gravina Island, about 3.0 miles south of South Vallenar Point. The site is in section 27, T. 75 S., R. 89 E., of the Copper River Meridian. It corresponds to loc. 52 in Elliott and others (1978). The location probably is accurate within 0.5 mile.

Geologic setting

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.
