Idarado kept the underground workings and mill operations open at Telluride's Pandora hardrock mine until 1978. Coal mining in Colorado dates back to 1859, when a pair of men began mining a coal deposit between the gold rush settlements of Denver and Boulder.

Milling. For both traditional underground and open pit mining, the rocks may have only a few percent (normally <%) uranium in them. The uranium then has to be removed from the rock and concentrated. The milling process involves crushing and pulverizing the rock into very fine fragments and adding water to create a slurry.
