Forsys Announces Up to 92% Recoveries from Heap Leach Laboratory Tests and Commencement of Optimization StudyTORONTO, ONTARIO--(Marketwire - Aug. 10, 2011) - Forsys Metals Corp. (TSX:FSY)(FRANKFURT:F2T)(NSX:FSY) ("Forsys" or the "Company") is pleased to announce positive uranium leaching results from laboratory tests to determine whether ore from its fully licensed Valencia Uranium Project could be economically recovered by heap leaching. The test program focused on the uranium recovery and reagent consumptions that are commercially achievable, and generating data to guide future development work by a heap leach process route.
Mintek of Johannesburg, South Africa, which was appointed as the laboratory facility to conduct the initial column leach test program, concluded that:
-> Ore from the Valencia Uranium Project is amenable to heap leaching.
- Good uranium extractions can be achieved under trickle-bed conditions.
- Sufficient uranium liberation is attainable from conventional crushing.
Up to 92% uranium dissolution was obtained in the column leach tests at a pH of about 0.7. Concurrently, 2 atmospheric batch leach tests were carried out to provide comparative leach results to the heap leach tests and determine any possible anomalies should they exist. The atmospheric batch leach test results supported the findings of the column leach results and no anomalies were found. Simulus, a leading Perth based engineering group, has been appointed to complete the recommended Phase 2 optimization study.
Marcel Hilmer, Chief Executive Officer of Forsys, commented, "Phase 1 results have confirmed our view of the benefits of heap leaching and that it appears viable as the primary mineral extraction method and may ultimately lead to reduced capital and operating expenditures and overall improved economics at our Namibian projects. We have commenced Phase 2 of laboratory testing and hope to provide further positive results before year end."
