Geologic setting

Geologic description

Significant Sn, W and Zn geochemical values were detected in calc-silicate rocks. Bedrock is mainly quartz-mica schist intruded by felsic igneous rock (Menzie and others, 1983). Four samples of calc-silicate rock contained 70-150 ppm Sn, up to 500 ppm W, 300-700 ppm Zn, and a trace of Au in one sample (Foster and others, 1984).
