SnapshotDaneros Mine is located in the White Canyon District. The project is a developed and permitted underground mine that was most recently in production in 2013.


IsoEnergy Ltd. 100 % Indirect
On October 27, 2021, pursuant to the Purchase Agreement, Consolidated Uranium Inc. (CUR) acquired from the Energy Fuels Parties a 100% interest in the Tony M, Daneros and Rim mines in Utah, as well as the Sage Plain property and eight U.S. Department of Energy Leases in Colorado.

On December 5, 2023, IsoEnergy Ltd. (“IsoEnergy”) (TSXV: ISO; OTCQX: ISENF) and Consolidated Uranium Inc. (“Consolidated Uranium” or “CUR”) (TSXV: CUR; OTCQX: CURUF) announced the successful completion of the previously announced arrangement (the “Arrangement” or the “Merger”) whereby IsoEnergy has acquired all of the issued and outstanding common shares of Consolidated Uranium (the “CUR Shares”). The Arrangement results in IsoEnergy acquiring 100% of the CUR Shares not already held by IsoEnergy or its affiliates and Consolidated Uranium becoming a wholly owned subsidiary of IsoEnergy.

Deposit type

  • Sandstone hosted


The Daneros uranium deposit can be classified as Phanerozoic Sandstone; Tabular/Peneconcordant; Basal-channel Type in the classification scheme of Dahlkamp (1993). The Shinarump Member of the Chinle is the only host rock horizon with this type of deposit on the property. The property is not known to hold any potential for any other type of deposit.

The uranium deposit at the Daneros Mine, like nearly all others in the White Canyon district, is in the lower part of the Shinarump, especially where it has scoured into the Moenkopi. The lithology, facies, sedimentary structures, and locations within the channel deposits all were important in controlling the migration of fluids and localization of the deposits. Coarser-grained rock is more favorable than finegrained sand or silt units. Most of the uranium mineralization is overlying impermeable siltstones of the Moenkopi or local siltstone lenses internal of the Shinarump. The lateral edges of channels where they are bounded by mudstones are also favorable locations for mineralization. Sandstones and conglomerates bounded on the top by siltstones or clay layers are also favorable. Intersections of channels and meanders have been found to be favored locations. The most favorable sites are in the coarser sandstone/conglomerates adjacent to finer sediments that contain vegetal matter. The uranium was transported into the area in oxidized groundwaters. The permeability differences related to the grain size of the various facies confined, concentrated, and slowed the flow of the oxidized waters. The accumulations of carbonaceous material created local reducing environments. These reducing conditions caused the dissolved uranium minerals to precipitate.

Uraninite (pitchblende) is by far the dominant primary uranium mineral in the Shinarump deposits. It occurs as distinct grains, fine grained coatings on and pore-fillings between detrital quartz grains, partial replacement of feldspar grains, and as replacement in carbonized wood and other remains of organic matter. Metallic sulfide minerals are often abundant. Where secondary oxidation has occurred, minor amounts of uranyl carbonates, sulfates, and phosphates are found. The source of the uranium is not well established. Overlying shaley units of the Chinle contain clays derived from volcanic ash that is uraniferous. The source area of the arkosic sediments was also a uranium-rich province.
