Key Highlights

The Federal Court ruled the August 2024 section 10 declaration over McPhillamys invalid on procedural grounds, and the matter returns to the minister for a fresh decision.
Regis maintained FY27 production guidance of 360,000 to 400,000 ounces.
Total FY26 dividends of 35 cents per share, fully franked, were declared.

On 14 October 2026 Regis Resources told the market that the Federal Court had ruled invalid the section 10 declaration made in August 2024 over its McPhillamys gold project in New South Wales. The court decided the declaration was procedurally defective rather than ruling on the heritage claims themselves, and the matter returns to the Commonwealth environment minister for a fresh decision. The company maintained its FY27 production guidance alongside the ruling. Regis declared total dividends of 35 cents per share for FY26, fully franked.

What the company actually does

Regis Resources Limited is an Australian gold producer with two sources of output. The wholly owned Duketon operations in the north eastern goldfields of Western Australia comprise open pit and underground mines feeding two processing hubs. The company also holds a 30 per cent interest in the Tropicana gold mine. Its principal development asset is McPhillamys, near Blayney in central New South Wales, a project held back since 2024 by a heritage protection declaration covering the proposed tailings storage area.

Latest verified developments

Regis requested a trading halt on 14 October 2026 and released the court outcome the same day. The judgment found the declaration invalid for procedural defects, including a want of procedural fairness, which leaves a redetermination open to the minister. A first quarter production release followed on 7 October 2026 and the full quarterly activities report on 20 October 2026, alongside the notice of annual general meeting. The company announced board succession and renewal on 15 October 2026 and lodged a Citi Australia conference presentation on 20 October 2026. Earlier, in July 2026, Regis withdrew from a proposed merger of equals with Vault Minerals and became entitled to a break fee of about A$50.7 million, which was received during the September quarter and reported within that quarter's cash generation.

Financial and operational evidence

For the financial year ended 30 June 2026 Regis reported gold sales revenue of A$2,349.1 million and a statutory net profit after tax of A$715.1 million, against A$254.4 million in FY25. Group production was 379,050 ounces at an all-in sustaining cost of A$2,945 an ounce, and the A$300 million revolving credit facility was undrawn at the balance date. In the September 2026 quarter the group produced 83,000 ounces, comprising 56,100 ounces from Duketon and 27,000 ounces from its share of Tropicana, and finished with A$1.28 billion in cash and bullion. Guidance of 360,000 to 400,000 ounces for FY27 was maintained. Total dividends declared for FY26 were 35 cents per share, fully franked, comprising a 15 cent interim, a 15 cent ordinary final and a 5 cent special.

Risks and pressure points

The ruling removes a legal obstacle without settling the project. The minister may make a fresh declaration, and an alternative waste landform design would carry its own approvals, capital and scheduling consequences; a final investment decision had been targeted for the first half of calendar 2028. Operationally, the September quarter delivered a little over a fifth of the lower bound of annual guidance. All-in sustaining cost guidance for FY27, at A$2,990 to A$3,390 an ounce, sits above the FY26 outcome of A$2,945.

Milestones to watch

The ministerial redetermination on McPhillamys is the clearest single item, and no timetable for it has been published. The annual general meeting, convened by a notice lodged on 20 October 2026, and the December 2026 quarterly report follow in the near term. Investors may be watching whether second half production recovers sufficiently to meet guidance, and how the cash and bullion balance is applied now that the Vault transaction has lapsed. Any move on an alternative waste landform design at McPhillamys would be one development to monitor.
