Geologic descriptionAs 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. |
