The Campbell prospect is on or surrounded by lands that have been conveyed to the Sealaska Corporation, who hold the surface and subsurface rights, or the land is under application for transfer to them.
Location: The Campbell prospect is about 1.4 miles northwest of Mount Jumbo and about 0.3 miles east-southeast of the center of section 21, T76S, R84E, M=?.
Geology: The Campbell prospect is in skarn near the contact of a small Cretaceous granodiorite stock that intrudes marble of the Wales Group of Late Proterozoic and Cambrian age (Herreid and others, 1978). The deposit consists of small, pyrrhotite-rich pods with chalcopyrite in the skarn. One sample contained 1,380 parts per million (ppm) copper, 20 ppm lead, 175 ppm zinc, 1.5 ppm silver, and a trace of gold. The prospect was explored by a 50-foot adit.
Workings: The only working consists of a 50-foot adit.
Age: Probably related to a nearby Cretaceous granodiorite intrusion.
Alteration: Deposit probably is genetically related to the skarn host rock.
Commodities (Major) - Ag, Cu, Zn; (Minor) - Au, Pb
Development Status: None
Deposit Model: Copper skarn (Cox and Singer, 1986; model 18b).
