After the Revenue Mill burned down in 1912, mining activity ceased until 1922 -23, when a small <br />amount of ore was mined Rehabilitation work occurred in 1936 -38, but no production was <br />recorded. Additional rehab work was done from 1943 to 1948 but again, little production was <br />recorded. In 1964, Federal Resources did further rehab work and extended a drift northwest from the <br />Virginius #1 shaft into the Monogahela workings area and the shaft was reconditioned down to the <br />210 level. A small amount of mining was done in this area at that time. <br />During the life of this initial mine over 100,000 tons of ore were mined, including the production of <br />over 100,000 ounces of gold, over 13 million ounces of silver, and almost 64 million ounces of lead. <br />No further activity took place until 1979, when Ranchers Exploration and Development Corporation <br />acquired the lease and rehabilitated the #1 shaft to the 700 level. A new drift was driven to the <br />southeast a distance of 2600 feet from the #1 shaft on the 550 level. An extensive in -mine drilling <br />program was initiated in this area and reserves of silver and sulfides were identified, but low metal <br />prices forced the mine into abandonment in 1984. <br />Sunshine Mining Company acquired the lease in 1995 and permitted the mine under the current <br />rules but abandoned the mine in 1997. An NPDES permit was also issued to Sunshine as part of the <br />permit process for the mine water discharging from the Revenue Portal. Wet tests were conducted <br />and the company was allowed to abandon this permit with no further action. The required <br />reclamation was also done, but it was minimal since no new disturbance was made and all <br />disturbance on the site was prior to the rules initiated in 1977. <br />Within the Sneffels Creek drainage liesthe Atlas Mine, Torpedo Eclipse Mine, Bimetallist Mine, <br />Virginius Mine, Humboldt Mine, Smuggler Mine, and the Mountain Top Mine, among others. The <br />area has been a hot bed of silver mining since the late 1800s, and the Revenue Mine in particular has <br />been the focal point of this activity. Substantial pre -law waste piles can be found throughout the <br />area, including a sizeable dump immediately north and west of the Revenue portal. <br />Revenue Mine August 2012 i - <br />
