[{"type":"text","content":"\n\n \n \n \n18 September 2023\nFirst Tin Plc\n(\"First Tin\" or \"the Company\")\nEnd-to-End Mineral Processing Testwork Successfully Completed on Taronga Tin Project Bulk Sample\n \nFirst Tin PLC, a tin development company with advanced, low capex projects in Germany and Australia, is pleased to report that results of the end-to-end mineral processing testwork have now been received and compiled on a bulk sample taken from an adit through the North Pit mineralisation at the Taronga tin project (average grade 0.18% Sn.) Based on a thorough review of this and other data, First Tin now believes that it has developed a simple and cost-effective processing option for the tin mineralisation found at the asset.\n \nAs recently reported, previous crush, jig and spiral test results confirmed the premise that the cassiterite (SnO2 - tin ore mineral) is easily liberated at a coarse crush size and that a good quality pre-concentrate can be obtained using very simple gravity separation techniques. \n \nUsing coarse gravity techniques only (i.e. no fine tin recovery) and a processing route that consists only of crushing, jigs, spirals, grinding and shaking tables, followed by standard tin dressing techniques including finer grinding and sulphide flotation, it has been demonstrated that 55-58% of the total tin is recovered into a plus 56% Sn, low impurity tin concentrate. An additional 5-6% recovery is possible from a fine tin circuit.\n \nDue to the simplicity of the coarse tin only circuit, this processing flow sheet has now been chosen as the most viable option for the DFS, with the possible addition of a fine tin recovery circuit and/or supplementary crushing options being investigated as part of future optimisation work to further increase recovery rates. Ongoing recovery studies on lower-grade samples are also currently in progress, designed to obtain a good grade-recovery curve for use in the DFS, which we aim to complete during Q1 2024. These results will be announced when received.\n \nSummary\n· &nb...
