[{"type":"text","content":"\n\n\n \n7 March 2024\nFirst Tin Plc\n(\"First Tin\" or \"the Company\")\nTaronga Gravity Circuit Mineral Processing Update\n \nResults of New Gravity Circuit Testwork at ALS Laboratory Return Excellent Recoveries, Significantly Improving on Previous Testwork\n \n \nFirst Tin PLC, a tin development company with advanced, low capex projects in Germany and Australia, is pleased to announce that additional mineral processing testwork for its Definitive Feasibility Study (\"DFS\") at its Taronga Tin Project (\"Taronga\") in Australia, has shown enhanced recoveries from the gravity circuit of the project.\n \nALS Laboratory in Burnie, Tasmania, one of the foremost laboratories for tin processing testwork worldwide, recently completed testwork on crushing preconcentrates of two samples from the Taronga project:\n \n1. A \"low grade\" bulk sample, blasted from the old Newmont adit in the North zone, with a head grade of 0.11% Sn.\n2. A composite \"variability\" sample of half core from throughout the deposit (both North and South zones), constructed to be close to the average composition and average head grade of the deposit, around 0.13% Sn.\nResults highlights:\n \n· Gravity circuit testwork on both the low grade bulk sample and the variability core sample crushing pre-concentrates has returned:\no Low grade (0.11% Sn): 71.5% tin recovery to a 69.8% Sn concentrate\no Variability (0.13% Sn): 72.5% tin recovery to a 60.1% Sn concentrate\n· These results are significant improvements on the previous recoveries for the high grade bulk sample (0.18% Sn), due to optimising the flowsheet based on the earlier work.\n· The results confirm that mineralisation with head grades at or below the average head grade of 0.13% Sn, return plus 70% recovery to the coarse tin gravity circuit.\n· Inclusion of a fine tin circuit will be examined later and this should increase the overall recovery even further.\n· Total recovery, including losses from the crushing pre-concentration, will be reported in the next few weeks.\nBased on learning from the previous testwork on the \"high grade\" sample, the recent ALS testwork more closely followed the revised processing flowsheet...
