Mt Magnet expansion at Ramelius: planning and geotechnical notes to FY30
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Ramelius Resources is advancing a major expansion of its Mt Magnet gold hub in Western Australia, targeting group production of 560,000–610,000 ounces per year by FY30, up 11 per cent on its October 2025 plan. The revised growth strategy lifts projected FY30 output by 205,000 ounces compared with FY24 levels, consolidating ore supply from satellite deposits into a central processing complex at Mt Magnet. For mine planners and geotechs, the scale-up implies longer pit lives, higher total movement and potential upgrades to haulage, waste storage and tailings capacity across the hub.
Technical Brief
- Centralisation at Mt Magnet implies longer average haul distances from satellites, affecting haul road design and fleet sizing.
- Higher ore throughput will require staged debottlenecking of crushing, grinding and leach circuits at the Mt Magnet plant.
- Tailings storage at Mt Magnet will need staged lifts or new cells to accommodate increased deposition volumes.
Our Take
The Mt Magnet hub expansion in Western Australia links directly to Ramelius Resources’ previously reported 500,000oz-per-year gold ambition, with the Primero EPC award indicating that the 11 per cent production uplift versus the October 2025 plan is now backed by committed plant capacity rather than just mine scheduling assumptions.
Recent coverage of Ramelius Resources in Western Australia, including the sale of the Edna May Gold Project to Forrestania Resources, suggests the company is recycling capital out of non-core gold assets to fund higher-return growth at the Mt Magnet gold mine and associated hubs.
Within our 1265 Mining stories, Ramelius stands out among Australian gold producers for pairing strong FY26 earnings margins with a multi-asset growth pipeline, meaning the FY30-focused Mt Magnet plan is being executed from a relatively robust balance-sheet and cash-flow position compared with many mid-tier gold peers in the region.
