A metallurgical optimisation upgrade at the Heemskirk tin project, in Tasmania, has resulted in a 34.2% increase in the project’s net present value, owner Stellar Resources reported on Tuesday. A 2013 prefeasibility study had estimated that a $114-million investment would be required to support an annual production of 4 327 t of tin-in-concentrate. At the time, the project was estimated to have a net present value of A$61-million, at a tin price of $25 500/t.
