|Location and accuracy||This prospect is at an elevation of about 100 feet near the south shoreline of Vixen Inlet. It about 1.1 mile southeast of Sunshine Island and about 0.5 mile west-northwest of the center of section 15, T. 70 S., R. 87 E.|
Geologic descriptionThis prospect consists of two short pits along a creek; the property was active from 1964 through 1967. The deposit consists of numerous barren to slightly mineralized quartz veins that contain minor pyrite and chalcopyrite (Maas and others, 1993, 1995). The veins cut banded, black and green phyllite. Eberlein and others (1983) and Brew (1996) assigned the rocks a Mesozoic or Paleozoic age; Gehrels and Berg (1992) tentatively mapped them as Jurassic or Cretaceous. Several samples taken by Maas and others (1993) contained up to 109 parts per million (ppm) copper and 1.3 ppm silver.
