BBX Minerals announce results of preliminary metallurgical testing from the Company's Tabocal prospect, approximately 2.7km east of the previously sampled areas at the Três Estados Project. The Company has conducted further metallurgical testwork at the Marcelo da Silva Pinto M.E. facility (Marcelo), using a similar process to that reported on January 9, 2018 for Ema and Três Estados bulk samples, but without a pre-leach step and varying the flux mix in the initial fusion. Four tests were conducted on 5kg sub-samples using different combinations of flux components on a homogenised 150kg bulk sample taken from fresh (unweathered) outcropping dolerite, displaying intense hydrothermal alteration (amphibolitization, chloritization and saussuritization) at the Tabocal prospect. Approximately 150kg of rock samples was collected from a single outcrop over an area of approximately 3 metres by 3 metres. After collection, the sample was sealed and transported directly to the Nomos laboratory in Rio de Janeiro for preparation. After crushing and pulverisation the samples were sent directly to the Marcelo facility in Rio de Janeiro for treatment. 5kg of each sample was smelted with a specific flux and a copper collector to form a copper-rich bar. Each bar was divided into four equal parts, one of which was dissolved in nitric acid and metals precipitated from the solution. The resultant precipitate was fused to form metallic buttons which were analysed by fire assay using a gravimetric finish. The other three quarters of each copper bar have been retained for additional testwork. The process was repeated on the slag form each fusion which was crushed, ground and refused and a second copper bar produced. The results from the two fusions, summarised in table 1 indicate that the more complex flux mix used in test TB-T411-1 resulted in significantly higher gold and silver recoveries. Testwork is continuing to confirm these conclusions.
