Regis reassesses ‘unviable’ $1b gold mine
Regis Resources (ASX: RRL) is proposing a new development approach for its McPhillamys mine in NSW, which was derailed in 2024 by an Indigenous heritage ruling.The ruling made in August 2024 — more than a year after the project was approved — denied the construction of a tailings dam near the Belubula River in an attempt to protect culturally significant land.The company took the decision to the Federal Court and the matter was heard by the court in December 2025.Regis has argued that the view held by the Federal Department of Climate Change, Energy, the Environment and Water (DCCEEW) changed after additional evidence was produced by an independent Aboriginal elder more than a year after approval was granted — believing that further investigation into the Dreaming story used as evidence should have taken place before the ruling was handed out.If Regis’ application is successful, the company will seek a declaration from a Federal Court judge that the 2024 ruling handed down by then Federal Environment Minister Tanya Plibersek is legally invalid and that the application be redetermined by a different minister.Following Regis’ challenge to the Federal Court, Minister Plibersek remained adamant in her ruling.“The truth is we are living in a country where we’ve got thousands of years of continuous culture and heritage. We’ve done a pretty bad job of protecting it in the past,” Minister Plibersek said.“Protecting cultural heritage and development are not mutually exclusive. We can have both.“Crucially, my decision is not to stop the mine. The company has indicated to me that it has assessed around four sites and 30 potential options for the tailings dam.”Following the ruling, contrary to Minister Plibersek’s declaration, Regis deemed the project as non-viable, stating it would take up to 10 years to identify and gain approval for an alternative tailings site, before taking out a non-cash impairment of $192m.With the Federal Court’s ruling pending, Regis continues to progress a dual-track strategy to return McPhillamys to an approvable status.In parallel with the ongoing court process, Regis has advanced work assessing the suitability of an integrated waste landform incorporating a form of co-disposal within the planned waste dump.Initial study outcomes indicate that the concept is technically feasible and further detailed engineering, environmental and commercial assessments are underway to progress facility design, approvals pathway and potential development timeframes.
