Location and accuracy This site is a rock pit on a logging road along Kennel Creek, about 3 miles south-southwest of the logging camp on Freshwater Bay. The pit is at an elevation of about 300 feet, 0.6 mile west-northwest of the center of sec. 16, T. 46 S., R. 63 E. It is location P-22 of Bittenbender and others (1999) and MAS no. 0021140308 (U.S. Bureau of Land Management, 2002). The location is accurate.

Geologic setting

Geologic description

This occurrence is near the center of a Jurassic intrusion that consist of quartz monzonite, alaskite, and monzonite, surrounded mainly by the Silurian and/or Devonian Kennel Creel Limestone (Lathram and others, 1965). Maas and others (1996) and Bittenbender and others (1999) have classified this as a porphyry deposit with minor skarn. High grade samples contained up to 0.2 percent molybdenum and 155 parts per million copper.
