About 1907, gold was discovered in a remote part of Churchill County, leading to the creation of the Aspen District. According to the Churchill County Eagle, a camp of 300 existed by April 1909 - an unlikely claim. Among the first to prospect in the district was Gay Reader, a reclusive miner from Aspen, Colorado. He made arrangements for groceries to be delivered by Firmin Bruner, who frequently made the run from Fallon to Berlin and other camps of the area.

In 1911, Reader left Aspen with plans to return later and construct a mill. After he failed to return, Silverino Penelas relocated and worked the property until an accident hospitalized him. Upon his return, it was found that ore he had stored was stolen by John P. Buzane (from nearby Buzanes Camp). Coupled with his failing health, Penelas decided to abandon the property. A last ditch effort to mine at Aspen was made in early 1931, when a group retimbered and extended Reader's workings, but after one shipment they too deserted the place.
