The habits of the deposits in the La Sal Trend have been reported to be typical of the Uravan Mineral Belt deposits.

The Morrison sediments accumulated as oxidized detritus in a fluvial environment. Individual deposits are localized in areas of reduced, gray sandstone and gray or green mudstone (Thamm et al., 1981). Most of the La Sal and Uravan Mineral Belt areas consist of oxidized sediments of the Morrison Formation, exhibiting red, hematite rich rocks. East of the Beaver, the channel appears to widen and contain large meanders as it continues through the Mike portion of the La Sal mine, the Snowball, and Pandora mines. The channel remains relatively straight and the uranium deposits get larger as it continues eastward through the Redd Block and Beaver mine deposits. Atomic Energy Commission, 1959) is located upstream in this tributary channel. The Energy Queen deposit appears to be at the location of the junction of a tributary channel that joins the main channel from the southwest. The La Sal Trend is a large channel of Top Rim sandstone which trends due east, possibly as a major trunk channel to distributaries that fanned-out to the east to make a portion of the Uravan Mineral Belt. Most mineralization is in trends where Top Rim sandstones are thick, usually 40 feet or greater. The location and shape of mineralized deposits are largely controlled by the permeability of the host sandstone. The Uravan Mineral Belt was defined by Fisher and Hilpert (1952) as a curved, elongated area in southwestern Colorado where the uraniumvanadium deposits in the Salt Wash Member of the Morrison Formation generally have closer spacing, larger size, and higher grade than those in adjacent areas and the region as a whole. The La Sal district uranium-vanadium deposits are a similar type to those elsewhere in the Uravan Mineral Belt. These classes are very similar to those of Dahlkamp (1993) Type 4-sandstone Subtype 4.1- tabular/peneconcordant Class 4.1.2 (a) Vanadium-Uranium (Salt Wash type) and Class 4.1.3-basal-channel (Chinle type). Any future deep drilling to explore for deposits in the Triassic basal Chinle Formation (Moss Back Member) would fit the DOE classification as Class 240- sandstone Subclass 243- channel controlled peneconcordant. Department of Energy’s (“DOE”) classification as defined by Austin and D’Andrea (Mickle and Mathews, 1978) Class 240 sandstone Subclass 244-nonchannel-controlled peneconcordant. The La Sal Project uranium-vanadium deposits in the Jurassic Salt Wash Member of the Morrison Formation are sandstone-type deposits that fit into the U.S.
