Whole-rock geochemical data for alkaline intrusive rocks in the Wet Mountains area of Custer and Fremont Counties, south-central Colorado, USA This data release contains the whole-rock major and trace element analyses of 51 samples of intrusive igneous rocks from the Wet Mountains area of Custer and Fremont counties of south-central Colorado, collected by U.S. Geological Survey (USGS) geologists. The samples were collected from breccias, veins and thin dikes, and a variety of carbonatite, felsic, mafic, and ultramafic intrusions across the area. The first 41 samples listed in this data release were collected in July 2007, originally as part of a reconnaissance study of the thorium deposits of the area (Van Gosen and others, 2009). The samples are grab samples from outcrops, shallow open-pit excavations, and mineral prospect trenches. The last 10 samples...

The Canyon deposit lies from about 750 to 2,000 ft (230 to 610 m) below the surface at latitude 35.88333 North, longitude -112.09583 West (datum WGS 1984). Energy Fuels, owners and operators of the property, has conducted extensive drilling into the Canyon deposit, which has defined the extent and characteristics of the ore bodies, leading to mine development. On a site visit in February 2018, Energy Fuels generously allowed the authors (U.S. Geological Survey geologists) to examine and...

Geochemistry data include major and trace element analytical results for 105 samples including alkaline igneous rocks, carbonatites, and weathered and oxidized samples. Samples were collected from surface exposures, a shallow temporary exploration trench, and drill core. Drill core samples are from exploration holes drilled by Rare Element Resources between 2009 and 2013 and from historical drill core from previous exploration companies. Rare earth element mineralization at Bear Lodge is hosted by carbonatite dikes,...
