Year Established/Founded

The camp of Keystone was established in 1868, primarily to support the Old Dominion Mining Company’s mining activities.

Keystone Nevada History

Keystone’s beginnings were modest, supported by a population of fifty and amenities like saloons. However, after an initial burst of activity, the camp quieted down for two decades. A silver strike in 1910 breathed new life into the camp, leading to intermittent operations up until as recently as 1990. Keystone’s landscape today is marked by old stone buildings and ruins, offering a tangible connection to its past.

Keystone’s story is one of repeated attempts to capitalize on the silver riches of Nevada. After its inception, the camp experienced a significant dip in activity, with the Keystone mine operating sporadically. The early 20th century saw a resurgence, thanks to a rich silver discovery, and mining operations continued sporadically over the next several decades. Various mining companies tried their luck in Keystone, from the Hot Creek Development Company in the 1910s to Nevada Goldfields, Inc., in 1990. Despite these efforts, Keystone never fully transformed from a camp into a thriving town, always remaining at the mercy of fluctuating mining fortunes.
