TORONTO, ONTARIO — (Marketwire) — 07/26/11 — (TSX VENTURE: UWE), a Canadian-based company, focused on exploration and resource expansion of and in South America, reports uranium recoveries of 82% from the first phase of ongoing metallurgical testwork on the in by SGS Minerals Services („SGS“) in its Lakefield, Ontario, laboratory.
„These positive initial metallurgical results constitute an important step in advancing the Kurupung Project from a uranium discovery to a deposit of significant potential value,“ said Dr. Richard Spencer, U3O8 Corp-s President and CEO. „A broad framework has now been established through which uranium can be extracted from the host rock and serves as a baseline from which additional metallurgical testing aims to refine and improve the efficiency of the extraction process. Infill drilling also continues to progress well in the Aricheng area towards our goal of increasing our current on the Kurupung Project by the end of 2011(1).“
Metallurgical Testwork
The metallurgical testing was conducted on hard-rock core samples from 24 bore holes in the and deposits(1) of the Kurupung Project. These bore holes are representative of potential bulk ore and include a range of samples from low-grade to high-grade material. The individual samples were shipped from Guyana to SGS-s facility in Lakefield, Ontario, where they were blended together to form one composite sample that has a grade of 0.1% U3O8.
The composite sample material was ground to a nominal 100 micrometres. Flotation was used to separate the bulk of the carbonate from the sample, which generated a high-carbonate fraction (approximately 20% of the original sample mass) and a low-carbonate fraction (about 80% of the original sample mass). The two fractions required different processing and leaching techniques as follows:
Testwork is ongoing to refine these broad initial metallurgical results. Planned tests aim to increase the efficiency of the flotation process used to separate the majority of uranium-bearing minerals from carbonate minerals, the principal consumer of acid. Greater efficiency in the flotation process should lead to a further reduction in acid consumption. Further work also aims to optimize the acid and carbonate leach steps applied to the flotation products.
