Barminco–Barrick Fourmile gold project: contract scope and schedule for mine planners

30 Second Briefing
Barminco has secured a 45‑month underground mining services contract worth about A$275 million (US$193 million) from Barrick for the Fourmile gold project in Nevada, with mobilisation scheduled to start in July 2026. The project, 100% owned by Barrick and located adjacent to the high‑grade Goldrush deposit on the Cortez trend, will focus on developing new underground access and ore drives to advance resource definition and early extraction. The deal extends Perenti’s North American footprint and signals continued investment in mechanised underground gold mining in the Carlin‑style systems of Nevada.
Technical Brief
- Contract scope centres on underground development mining services rather than full stoping or processing operations.
- Mechanised underground fleet is expected, consistent with Barminco’s standard hard-rock equipment profile in North America.
- Long contract term supports staged access development, resource definition drilling platforms and early ore drive establishment.
- Barrick’s 100% ownership of Fourmile simplifies decision-making on mine design, sequencing and capital deployment.
Our Take
With Barminco also recently landing the $850 million underground contract at Bellevue gold in Western Australia, our coverage suggests Perenti is deliberately skewing its portfolio toward high‑grade underground gold work, which can buffer earnings against open‑pit margin volatility.
The 45‑month term starting in July 2026 means Fourmile will overlap with Barminco’s extended Duketon and Bellevue contracts, signalling that Perenti will need to manage a tight labour and fleet schedule across Nevada and Western Australia at a time when underground specialists are already in high demand.
Gold projects dominate the higher‑value contract awards in our mining database, and this Nevada work for Barrick reinforces that gold remains the most consistently bankable commodity for long‑duration underground services agreements compared with more cyclical base metals.
