TAILINGS STORAGE FACILITY (TSF) The TSF design concept features an above-ground impoundment with a single perimeter embankment. The maximum embankment height is 10.6 m and the total landform height at Life of Mine (LOM) is predicted to be RL 429.8 m, 14.8 m above ground level. The TSF classifies as Category 2, having a maximum embankment height below 15m and hazard rating of “medium”. The facility is designed to be unlined as it is expected that percolation rates from thickened tailings is low as there is less pore water available to seep into the ground. Independent consultants SRK, conducted a site investigation with the objective of determining foundation conditions for the TSF, identifying borrow materials in the area and investigating features of the terrain such as creeks and rock outcrops. Samples from potential borrow material were tested and a physical tailings characterisation conducted as part of this investigation. Tailings testing included rheological testing.
