Processing

The process plant at Savannah comprises a single stage crusher, SAG mill, flotation, thickening and filtering stages to produce a bulk nickel, copper, cobalt concentrate. Metallurgically the plant continues to perform extremely well. Nickel recovery averaged 86% for the year and cobalt averaged 90%, both well above design of 78% and 69% respectively. Copper recovery averaged 97% for the year, which is as designed. The plant was originally designed for a throughput of 750,000 tonnes per annum, but has consistently outperformed the design specifications. Process personnel are confident that the mill can operate up to a capacity of 900-950,000 tonnes per annum.
