30 Second Briefing
Medallion Metals has named Macmahon Underground as preferred tenderer for the underground mining contract at the Ravensthorpe gold project in Western Australia, covering portal establishment and initial mine development. The scope is expected to include decline access, level development and associated ground support, with Macmahon to deploy its underground fleet and technical services under a single integrated contract. For geotechnical and mine planners, the decision signals a move towards contractor-led design and execution for early-life underground access at Ravensthorpe.
Technical Brief
- Scope is framed as a single integrated underground mining contract rather than multiple discrete work packages.
Our Take
Macmahon Underground’s selection at Medallion Metals’ Ravensthorpe gold project follows its recent wins at Mt Marion (lithium) and the Central Tanami gold project, signalling that Western Australian operators are favouring contractors with a mixed commodity underground portfolio for new declines.
Within our mining-projects coverage, Western Australia gold items increasingly reference approvals and closure planning (e.g. Maritana Minerals’ Black Swan Processing Hub), so Ravensthorpe’s contractor move likely precedes a near-term push on permitting and detailed mine design rather than early-stage exploration work.
For Medallion Metals, bringing in Macmahon Underground at this stage positions Ravensthorpe to compete for capital against other Australian gold projects in our database that are already pairing underground development with existing processing hubs, potentially shortening the path to first ore if toll treatment options are available.
