On December 22, 2021, U3O8 Corp. (TSXV: UWE.H), ("U3O8" or the "Company") announced that pursuant to the Option Agreement dated December 14, 2020 the transfer of the mineral properties that constitute the Laguna Salada Project located in Argentina, was completed.

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.

Summary:

Uranium-vanadium mineralisation in the Laguna Salada Project has the principal characteristics of surficial uranium deposits according to the classification of Toens et al., 1984.

Two principal styles of uranium-vanadium mineralisation have been identified at Laguna Salada as follows:

- Of principal economic interest is a tabular, gently undulating layer that contains yellow-green uranium-vanadium minerals at shallow depth within unconsolidated, sandy gravel. This style of mineralisation occurs in the Guanaco and Lago Seco areas in gravel-dominated clastic facies of different ages – Pleistocene at Guanaco and Holocene at Lago Seco. Powdery and finely crystalline uranium-vanadium minerals occur between the grains in the sandy matrix of the gravel and also as partial coatings on sand grains and clasts. Studies indicate that approximately 10% of the contained uranium occurs as rinds on clasts. Carnotite (K2(UO2)2(VO4)2.3H2O) is the dominant uranium-vanadium mineral and has a variable habit from slightly cohesive to compact masses of crystals.

- The second style of mineralisation is found in the Buried Lake area where carnotite straddles the unconformity between the gravel sequence and the underlying, organic-rich mudstones. Mineralisation within this layer occurs in interstices in the sandy matrix and on pebbles in the gravel as well as within cracks and associated with organic material in the underlying mudstone. The true potential of this style of mineralisation at Laguna Salada is undefined at this time.

Guanaco Area
Uranium-vanadium mineralisation in the Guanaco area is closely associated with carbonate distribution in the gravel layers of the sedimentary sequence of the Pampa de Arroqui Formation. Mineralisation is generally evident as a yellow-green staining on the sides of trench walls and the generally tabular mineralised zone is marked by abruptly gradational, slightly undulating boundaries that cross-cut contacts between conglomerate and sand layers.

The generally sub-horizontal layer of mineralisation at Guanaco extends from beneath the patchy soil cover to a maximum depth of 3m to 4m. The mineralised area that has grades above 50ppm U3O8 ranges from 0.2m to 2m thick with an average of 0.94m in the Guanaco area. Mineralisation at Guanaco is made up of a number of mineralised sheets, each of which is several square kilometres in extent in which mineralisation shows remarkable continuity. Each mineralised sheet is separated from the next by a gap of lower-grade mineralisation that may be up to 200m wide.

Lago Seco Area
Uranium mineralisation in the Lago Seco sector covers an area of more than 25km² and lies within 1m of surface beneath poorly developed, partial soil cover. The average thickness of the mineralised interval in trenches with grades above 50ppm U3O8 is 0.85m with a range between 0.3m and 1.9m. Mineralisation forms a sub-horizontal layer that is associated with carbonate and gypsum that has formed partially cemented nodules in the gravel and sand facies of the Gran Laguna Salada Formation. The majority of the uranium mineralisation is located in the matrix of the gravel with a lesser component encrusting clasts.
