During the late 1980s, exploration for gold was conducted by three companies: Newmont, Rhude and Fryberger, and Resource Exploration. This phase of exploration was prompted by an earlier mention of a gold discovery by J.W. Gruner in 1924 (Grout, 1937). Reportedly, Gruner found visible gold and arsenopyrite in veins associated with a quartzofeldspathic intrusion in railroad cuts near Virginia.
