Lunnon Metals closes out Lady Herial gold production - Australian Mining

AI desk brief

Lunnon Metals says its completed Lady Herial open pit in Western Australia is set to deliver about A$39 million in pre-tax free cash flow, after producing slightly more gold than the feasibility study forecast. The mine wrapped in early August ahead of schedule, with final reconciliation now underway.

The operation mined 303,437 tonnes at 1.68 g/t gold and sold 14,910 ounces under its Ore Purchase Agreement with Gold Fields’ St Ives Gold Mining Company. Gold output came in at 100.7% of the feasibility study forecast even though mined grade was 11.1% lower, helped by ore tonnes running 13.1% above plan due to dilution and extra ore blocks.

Revenue was A$93.26 million versus a feasibility estimate of A$92.54 million, while total operating costs came in at A$31.62 million, 5.1% above forecast because of the extra tonnes hauled and processed. Lunnon’s share of pre-tax free cash flow was about A$39 million, 3.5% below the study estimate, with an unaudited cash balance of A$41.4 million at Aug. 31.

For the broader gold market, this is a small supply-side positive from an Australian producer rather than a macro driver. The immediate trader takeaway is limited; the main relevance is company execution, near-term cash generation, and the fact Lunnon is now funding a A$13 million drilling program for FY27 from a strong balance sheet.
