Jasperoid breccia in the halo of the magnetic anomaly in Figure 1, with intense epithermal silicification, strong oxide development, clay altered volcanic breccia fragments, and strongly anomalous manganese, barite, molybdenum and mercury geochemistry. The outcrop is within clay-altered volcanic rocks which cover the western flank of the Reveille Range, and is located on the regional, north-south range fault and caldera-bounding ring fault which is believed to control the upward ascent of the source silver-copper mineralizing fluids at Reveille.
