Leadville is located about 37 miles north of Gerlach. Development work began after lead-silver discoveries in 1909, and the district produced modestly until as late as 1940/41. Lead and silver ore was mined from the Tohoqua Mine, from quartz veins. Minor deposits of zinc and gold were also found, as well as niter in crevices of rhyolite uncovered on the western side of the range. In 1920 the Leading Mining Company took possession of the area. Production under this concern was $153,000 in 1921 and $254,600 in 1922. The property consisted of three main claims developed by two shafts, a 1700 foot tunnel, and a 500 foot winze equipped with two 75 and one 100-horse power and semi-diesel engine, compressor, electric locomotive, auto trucks, 7500-foot water line, and 30,000 gallon tank. Also in operation was a 35-ton mill and flotation plant. All this was incorporated in 1920 with capital stock of $1,500,000.

Like all mining activities, ore petered out, and production ceased. Still remaining is the Blacksmith shop, two collapsed buildings, and extensive tailings.
