Location: This prospect is near the southeast tip of the peninsula that juts out to the east between Mallard and Stone Rock Bays. It is just north of the midpoint of the south boundary of section 8, T. 82 S, R. 90 E. This prospect may be in the Prince Rupert quadrangle or extend into it.
Geology: This prospect is on several claims that have been explored by only a few shallow pits. The deposit consists of radioactive andesite(?) dikes that cut Silurian or Ordovician syenite (MacKevett, 1963; Gehrels, 1992). The dikes are highly altered and consist mainly of chlorite and clay minerals. The dikes contain two sets of veinlets. The older set contains sparse radioactive minerals, probably monazite, and is rich in quartz and hematite. The younger set is not radioactive and consists mainly of calcite. The prospects were sampled by Maas and others (1991). Several samples contained up to 132 parts per billion gold, 0.27 percent copper, 331 parts per million (ppm) zinc, 1,080 ppm uranium, 1.44 percent cerium, 0.723 percent lanthanum, and 54 ppm yttrium.
Workings: Explored by a few shallow pits.
Age: Related to radioactive dikes of unknown age that cut Silurian or Ordovician syenite.
Alteration: Radioactive dikes are almost completely altered to chlorite and clay minerals.
Commodities (Major) - Au, Ce, Cu, La, U; (Minor) - Y, Zn
Development Status: None
Deposit Model: Radioactive dikes with REE minerals.
