Mine Life10 years (as of Jan 1, 2014)
In September 2014, the Company reported a positive PEA on Laguna Salada which showed low production cost potential. Since then, technological improvements in recovery methods and the relative values of the potential uranium and vanadium revenue streams have resulted in an ongoing re-assessment of the PEA assumptions. Due to the sustained bear market in uranium, and the associated difficulty of attracting capital to advance uranium projects at that time, Management determined that the Laguna Salada Project was impaired at December 31, 2019 and has written the asset value of the Project down to $Nil.

On December 14, 2020, the Company announced that it had entered an option agreement to sell its Laguna Salada Project in Argentina.

December 22, 2021 - U3O8 Corp. (TSXV: UWE.H), ("U3O8" or the "Company") announces 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, has been completed. On December 21, 2021 and upon transfer of the properties comprising Laguna Salada to Consolidated Uranium Inc. ("CUR"), CUR issued 675,675 common shares in the capital of CUR ("CUR Shares") to the Company.

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.


Mining Methods

  • Surface miner
  • Truck & Shovel / Loader


Summary:

Continuous surface mining
The mining operation contemplates the use of two Wirtgen SM 2200 (400tph capacity) continuous surface miners. This model of surface miner has a cutting width of 2.2m and a variable cutting depth to a maximum of 30cm.

The mining operation is contemplated to follow the procedure outlined below:

- Removal of the overlying soil by grader with FELs filling truck- trailers that would transport the soil for immediate spreading by bulldozer and grader over backfill at the trailing edge of the mining strip, or for temporary stockpiling adjacent to the trailing edge;

- Barren overburden gravel cut by the surface miner would be fed up a conveyor belt system and either discharged directly back into the strip in the trench from which mineralised gravel had previously been completely removed, or into 50t truck- trailers for backfill at the trailing edge of the mining excavation. Any excess backfill would be temporarily stored in piles adjacent to the trailing edge of the excavation;

- Once the overburden had been removed, excavation of the exposed mineralised layer would commence with the surface miner making multiple passes along the trench, the number of passes being dictated by the thickness of the mineralised unit and the constraint of the 30cm maximum cutting depth. 50t truck-trailer units loaded by the continuous miner would transport the mineralised material to the semi-mobile scrub- screen trains for beneficiation; and

- Mineralised material would be discharged from the truck- trailers directly into the primary hopper at the beneficiation unit or stockpiled on a patio adjacent to the hopper. Oversized gravel from the beneficiation units would be trucked to the trailing edge of the mining strip where reclamation would be ongoing.

Conventional Mining
Areas of irregular topography on the margins of the gravel mesas would be mined with shovels or bulldozers, with the gravel being lifted into truck-trailer units with FELs. There is typically no soil cover in these areas of irregular topography, and hence there is no necessity for stripping this component of the overburden prior to mining. Barren gravel overburden would be stockpiled adjacent to the excavation while the mineralised layer is removed and beneficiated.

Summary:

Carnotite, the principal uranium-vanadium mineral at Laguna Salada, occurs as a powdery filling between the sand grains and as a partial rim on pebbles in the gravel. To upgrade the feed to the plant, the carnotite-bearing material would be separated from the gangue material in semi-mobile beneficiation units comprising of scrubbing and screening stages.

In the scrubbing stage, ROM material is slurried in saline water and passed through rotating scrubber units. Discharge from the scrubber units will pass through trommel screens to remove coarser +3mm particles, after which the -3mm material will pass through a number of classification steps to ultimately isolate only the <75µm fraction for further treatment in the Hydromet Plant. From the beneficiation plants, the upgraded and significantly reduced tonnage of fine uranium-bearing material is received in the Hydromet Plant concentrate thickener feed tank as slurry in saline water.
