[{"type":"text","content":"\n\n\n \n \n7 August 2024\nFirst Tin Plc\n(\"First Tin\" or \"the Company\")\nNew Taronga Mineral Processing Testwork Shows Plus 75% End-to-End Tin Recovery from a Higher-Grade Sample\n \nFirst Tin PLC, a tin development company with advanced, low capex projects in Germany and Australia, is pleased to announce that new mineral processing testwork at its Taronga Tin Project (\"Taronga\") in Australia suggests better recoveries than those previously reported and used in the Definitive Feasibility Study (\"DFS\").\nHighlights include:\n \n· Crushing recovery of 91.2% of contained tin\n· Coarse gravity circuit recovery of 82.9% of gravity feed tin\n· End to end recovery of 75.6% tin to a 66.7% Sn concentrate\nThis testwork follows the current processing facility design. \n \nThe crushing recovery of 91.2% of contained tin, previously reported on 25 April 2024, combined conventional and 1st pass vertical shaft impact (\"VSI\") crushing from a high-grade bulk sample with head grade 0.15% Sn. The coarse gravity circuit concentration recovery on this material of 82.9% is significantly higher than the previously reported 71.5% recovery from a low-grade sample (head grade, 0.10% Sn).\n \nIn parallel testing, recovery of an additional 4.0% of starting tin to a 71.4% Sn concentrate has been obtained from a 2nd pass through the VSI followed by coarse gravity circuit processing. This shows the potential value of adding a second VSI to the circuit, which will be investigated as part of the DFS optimisation work.\n \nA 4.5% recovery of starting tin to a 14.0% Sn concentrate has also been obtained by initial testwork on a fine tin circuit. While no fine tin circuit is currently proposed at Taronga, this testwork indicates the potential additional recovery and such a circuit could be added at a later stage.\n \nFirst Tin CEO, Bill Scotting commented:\n \n\"The results of this testwork are very encouraging and confirm the readily treatable and upgrading nature of the Taronga mineralisation. Recoveries of over 75% tin from a higher-grade sample to a high-quality concentrate from the simple, coarse gravity tin circuit are much better than the recoveries used in the recently announced DFS....
