Australian miner New Century Resources has outlined “highly attractive economics” in the PFS that supports production of 555,000tpa copper and 320,000ozpa gold in concentrate over an initial 25 years from the restart of underground operations at its Mt Lyell mine in Tasmania. The study estimates pre-production capital cost of $A279M and average C1 costs of $1.89/lb copper.
The low-cost, long-life operation is calculated to deliver pre-tax NPV at 7% of $560M, IRR of 22% and LOM net cash flow of $1.08B.
The company has approved an immediate move to a full FS, due in the Sept 2023 qtr.
