The Bovard Mining District, located in the Gabbs Valley Range, Mineral County, Nevada produced about $360,000.00 in gold and silver. The mineralization is of the epithermal vein type. The district is underlain by a thick sequence of Tertiary ashflow tuffs, which have been highly faulted by movements of the Walker Lane, a regional northwest-trending lineament of significant right lateral strike-slip movement. Two major strike-slip faults, as well as numerous secondary oblique-slip and normal faults pass through the area. These faults have allowed the passage of hydrothermal fluids which were the source of the mineralization and widespread hydro- thermal alteration of the Tertiary volcanics. Alteration is sericitic along the faults and propylitic away from the faults. The primary sericitic alteration has been dated at 22.6 + 0.7 m.y. by the K-Ar method. Alunite, dated at A.7 + 0.9 m.y. found in the Golden Pen Mine is considered to be a supergene alteration mineral formed by oxidizing/weathering of the area.
