The Idarado Mine was a mining operation in the San Juan Mountains of Ouray County, Colorado near the now-ghost town of Guston, producing primarily lead, zinc and silver along with small amounts of gold and copper. The mine is within the Sneffels-Red Mountain-Telluride mining district. The remains of the operation are visible from the Million Dollar Highway, north of Red Mountain Pass, between Ouray and Silverton, Colorado. The tunnels of the Idarado extend some 5 miles (8 km) west under 13,000 foot (4,000 m) mountains to the Pandora Mill near Telluride, a trip of more than 60 miles (100 km) by highway.
