Location and accuracy	The Mad Dog 2 prospect is about 0.9 mile south-southeast of the east end of Harvey Lake at an elevation of about 400 feet. It is near the northwest corner of section 36, T. 61 S., R. 79 E.

Geologic setting

Geologic description Since the 1970s much of Woewodski Island has been covered by claims held by a succession of companies: Resource Associates of Alaska, Cominco Exploration, Colony Pacific, Amselco, Kennecott Exploration, Westmin Resources, and currently (2008) the Bravo Venture Group. This prospect probably was within those claims several times and it is under claim in 2008. In 1998, two holes were drilled on the Mad Dog 2 prospect by P. Beardslee (Still and others, 2002). Most of the area is heavily vegetated. The sparse outcrop consists of metamorphosed intermediate to felsic volcanic rocks of the Triassic Hyd Formation (Brew, 1997; Karl and others, 1999). Near the 1998 drill site, Still and others (2002) located an outcrop of schist with a band of pyrite, chalcopyrite, and sphalerite 0.3 to 0.8 feet thick. Six samples contained 67 to 2,867 parts per billion gold, 2.4 to 27.1 parts per million (ppm) silver, 240 to 1,512 ppm copper, and 732 ppm to 2.9 percent zinc. The drill holes were said to miss any significant mineralization.

Mineral deposit model	Kuroko massive sulfide (Cox and Singer, 1986; model 28a).
Mineral deposit model number	28a
Age of mineralization	Late Triassic based on the age of the host rock and similarities to massive sulfide deposits in the Duncan-Zarembo belt of mineralization.
Alteration of deposit	None specifically noted.
