First Tin PLC has announced the results of crushing pre-concentration testwork on bulk samples from its Taronga tin project in Australia. The testwork confirms that coarse crushing and screening can achieve liberation of cassiterite, resulting in a significant increase in tin grade and a decrease in mass going through the processing plant. Two samples were tested, one with a high grade of 0.18% Sn and the other with a low grade of 0.10% Sn. The high-grade sample was upgraded from 0.18% Sn to 0.30% Sn, while the low-grade sample was upgraded from 0.10% Sn to 0.15% Sn. The results confirm that cassiterite can be easily liberated at a coarse crush size, allowing for a smaller processing facility and higher starting grade. Gravity separation testwork is currently underway, and overall results will be announced shortly. The CEO of First Tin, Thomas Buenger, expressed satisfaction with the results, stating that the simple and low-cost beneficiation process will result in relatively low capital and operating costs for the Taronga project. The project is owned by First Tin's Australian subsidiary, Taronga Mines Pty Ltd.
