Test work has been conducted by PESCO, a DMS (WJO) expert in South Africa, on a bulk sample of 2 tonnes which is a potentially representative sample of the V1, V2 pegmatite bodies. These pits were previously identified by AfriTin as priority targets to supply feed to the upgraded processing plant at Uis.\nHighlights:\n• >85% stage-1 tin recoveries in 2.66 and 2.62 g/cm3 cut densities\n• Up to 91% recoveries in second-stage separation (at a cut density of 2.9 g/cm3)\n• >60% SnO2 grade in the final concentrate following removal of muscovite (a potential by-product)\nThese initial results confirm the beneficiation potential of the Uis pegmatites to produce a high-grade tin concentrate from a coarse run-of-mine feed. Further test work and alternatives are ongoing to potentially enhance these results and to further prove the beneficiation capability of the fine fraction arising through the crushing of the ore.\nAnthony Viljoen, CEO of AfriTin Mining, said: \"The excellent recoveries achieved in this bulk test work highlight the potential of concentrating mined material, to produce the output of tin concentrate from a significant tin and multi commodity deposit outlined at IPO. The completion of this test work has been a key element of the final design for our phase 1 processing plant at the historic Uis mine and bodes well for the expansion during Phase 2 of the project which envisages a full-scale production facility of 3 million tonnes of ore per annum. The company remains on target for the production of first tin concentrate during Q4 2018.\"\n \nSummarised Results of Test Work Performed\nThe principle of Dense Medium Separa...
