ORE SYSTEMS CONSULTING - Marshall Zone

Figure 9. Plan view of the Marshall Zone, showing the lowest volcanic units intersected by drilling. Along the northern side of the Marshall Zone -- which is hosted entirely by rhyolites -- drillholes ended in either rhyolite A or rhyolite B. This indicates that the contact between rhyolites and underlying mafic volcanic rocks of the Price Formation had not been reached. The nearby Battle and H-W massive sulfide deposits are hosted at this contact (Fig. 1).
