Nevada Rand is a low to intermediate sulphidation epithermal system. The property is in a district of tertiary volcanic rocks, mainly andesite and rhyolite. Mineralization occurs in highly altered andesite.
In the area of the shaft, highly elevated gold and silver values were reported at a vertical depth of 90 feet and continued to the bottom of the shaft at 450 feet. There are many reported shipments grading several ounces to the ton gold and several tens of ounces to the ton silver. The mineralization reported has a high silver to gold ratio. The occurrence of argentite, polybasite, and pyrargyrite are indicative of the high-grade portions of this type of epithermal setting.
Old mine dumps and surface alteration trace the zone for over two kilometres. More mine dumps and alteration zones across the gully are indicative of parallel structures. Other than the shaft accessed underground sampling before 1925, this robust epithermal system has never been explored using modern techniques. The property has never been drilled.
