U3O8 Corp. (TSXV:UWE) announced positive alkaline leach results on the uranium- and vanadium-bearing gravels from the Guanaco area of the Laguna Salada Project, Chubut Province, Argentina.
The press release is quoted as saying:
The Laguna Salada Project contains two slightly different types of gravel located in distinct areas: the Guanaco and the Lago Seco sectors. Both gravels are soft and unconsolidated. Samples from various sites in each area were excavated with a backhoe and sent, without any processing or crushing, to SGS Lakefield’s laboratory in Lakefield, Ontario, where they were combined into one large sample from each area and underwent metallurgical testing.
U3O8 Corp.’s President and CEO, Richard Spencer said:
“This excellent uranium recovery using alkaline leach – which is potentially lower cost than acid leach due to the modest reagent consumption expected – could further enhance the economic viability of the Laguna Salada as a potentially low-cost project.” “Laguna Salada has many positive characteristics. Firstly, uranium and vanadium lie within a few metres from surface in soft, unconsolidated gravel that should be amenable to low-cost mining techniques with no blasting or crushing required. Secondly, simple screening separation of the pebbles and coarse sand concentrates the uranium-vanadium in the fine material and increases uranium grades to approximately 620-670ppm – comparable to the head grades of similar deposits operating elsewhere in the world(1). Thirdly, most of the fine metal-rich material in the Guanaco area, which constitutes 90% of the Laguna Salada deposit, can be leached quickly with alkaline reagents achieving maximum uranium recoveries in only four hours. Metallurgical testing will be ongoing to optimize the recovery and beneficiation results that we have achieved to date.”
