Geologic setting

Geologic description

As described by Maas and others (1991, 1995), the Stockton Quartz prospect has a flooded shaft with a small dump. The rocks on the dump consist of quartz and blocks of greenstone. Two samples contained 9 and 20 parts per billion gold. Herreid (1967) maps the rocks near the prospect as part of a band of greenschist in the Wales Group of Late Proterozoic and Cambrian age. The Wales Group rocks rocks in the Dolomi area are folded into a large dome centered over the eastern third of Paul Lake, and consist of several marble layers 200 to 1300 feet thick, interbedded with calcareous chlorite schist and marble.

Mineral deposit model Probably a low-sulfide, brecciated gold-quartz vein (Cox and Singer, 1986; model 36a).
Mineral deposit model number 36a
Age of mineralization The deposit is younger than the Late Proterozoic or Cambrian host rocks.

Production and reserves

Workings or exploration The only evidence of workings is a flooded shaft and a small dump. The prospect is on a patented claim.
