Geology
AlterationThe rocks exhibit pervasive propylitic alteration consisting of chlorite, epidote, and pyrite. The breccia bodies in the northern area are altered to quartz-sericite-pyrite. Wall rock adjoining the breccias varies from pyritized volcanics to malachite-chalcopyrite-chalcopyrite-bearing porphyritic diorite, whose feldspar phenocrysts are altered to clay.
