U3O8 Corp. announced uranium and vanadium assays from exploration trenching of soft gravel and sand in the La Rosada area, which the Company considers to be an extension of the Laguna Salada Deposit. Uranium-Vanadium – Bearing Gravel and Sand: Gravel at La Rosada and Laguna Salada have similar general characteristics. At Laguna Salada, however, the gravel forms a tabular sheet deposited in an outwash plain while at La Rosada, gravel occupies northeast- to east-trending channels that are about 150 metres wide, and the one that has been most extensively explored is at least 2 kilometres long. Similar northeast- to east-orientated trends of radiation measured in radon cups in the area south of La Rosada may be indicative of similar mineralized channels in that area. The channel-constrained distribution of gravel is a feature that La Rosada has in common with the Langer Heinrich Deposit in Namibia. A sand layer that lies beneath the gravel at La Rosada may also have been preserved in channel features. The sand layer is extremely friable, and very significantly, is well mineralized in some areas where it has been exposed in exploration trenches. The sand layer has characteristics that are similar to the unconsolidated sands that host the Tubas Uranium Deposit in Namibia and represents a target in its own right at La Rosada. Uranium-vanadium – bearing rhyolitic volcanic tuff, assay results from which were reported on January 11, 2017, lie adjacent to and beneath the sand layer at La Rosada. Beneficiation: The key to the Laguna Salada Deposit is the ease with which the powdery uranium-vanadium mineral, carnotite, can be washed off sand grains and pebbles, concentrating in the fine-grained material. This grade is derived from a large sample in which all the material, including the barren pebbles and sand grains, have been crushed and assayed with the uranium-vanadium – bearing material that coats the grains. These grades provide the raw data that are necessary for future resource estimation. The grade of the fine component, composed of grains less than 0.15 millimetres in diameter, that was separated from the pebbles and sand by sieving, has an average grade of 0.5% (5,319ppm) U3O8, with a sample that spiked to 2% U3O8. The average grade of vanadium of the fine material is 0.23% (2,308ppm) V2O5. The average thickness of the gravel is 0.5 metres, with mineralization starting from 0.3 to 0.7 metres below surface. Only the fine component of the gravel would be processed for uranium and vanadium extraction. Results from the unconsolidated sand layer that lies beneath the gravel at La Rosada show that its uranium and vanadium are also concentrated into the fine material by washing and sieving the sand. The average grade of the sand is 726ppm U3O8 while the fine component has a grade of 1,102ppm (0.1%) U3O8. Vanadium assays average 681ppm in the raw sand and 924ppm V2O5 in the fine component. The average thickness of the sand layer is 0.7 metres. Where gravel and sand are mineralized in the same trench, the combined average thickness of the uranium-vanadium – bearing layer is 1.3 metres with an average grade, in the fine material, of 0.33% (3,355ppm) U3O8 and 0.16% (1,584ppm) V2O5.
