Geologic setting

Geologic description

This occurrence consists of an auriferous, pyrite-bearing quartz vein. A select sample of the quartz vein contains 810 ppb gold (Eden, 2000). Eden indicates that this vein is an extension of a system of gold-quartz veins in the Nolan area. The rocks in the area consist of quartz-mica schist interlayered with chlorite schist and phyllite (Eden, 2000). No other information is available.
