Ramelius kicks off Eridanus gold mine expansion - Australian Mining

AI desk brief

Article summary

Ramelius Resources has begun the stage 3 open-pit cutback at Eridanus in Western Australia to supply additional ore to its Mt Magnet processing hub over coming years. Eridanus’ June 2025 mineral resource estimate was approximately 30 million tonnes at 1.6 grams per tonne gold for 1.5 million ounces; separately, group ore reserves rose 79% to 4.3 million ounces in FY26. Ramelius’ expanded group production target is 560,000–610,000 ounces in FY30, supported by mining developments and a contracted new three-million-tonne-per-annum circuit that would lift Mt Magnet’s installed processing capacity to approximately five million tonnes annually. The wider growth programme also includes Dalgaranga ore sources and the advancing Rebecca–Roe project.

Market implications · analysis

The cutback and contracted processing expansion could support additional company-level gold supply over several years, conditional on execution and ore delivery. However, the article does not quantify Eridanus’ incremental annual production, commissioning timing or net contribution to global supply, so a directional near-term bullion effect is not established. Evidence is concrete on development commencement and stated capacity plans, but limited for estimating future refined output or spot-price consequences.
