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

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

    First reported on International Mining – News

    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.

    PLS Pilgangoora 22-sorter TOMRA contract: process design notes for engineers

    TOMRA Mining has secured a contract from Pilgangoora Operations Pty Ltd, a PLS Group subsidiary, to supply 22 sensor-based ore sorters for the P2000 Expansion Project at the Pilgangoora lithium operation in Western Australia. The installation is part of PLS’ pre-Final Investment Decision early works, signalling commitment to large-scale sorting ahead of full project sanction. For process engineers, the move points to increased reliance on front-end sensor-based separation to upgrade run-of-mine feed and manage lithia grade variability before downstream concentration.

    Macmahon Contractors has secured a 42‑month extension to provide contract mining services at Greatland Resources’ Telfer Gold Mine in Western Australia, valued at A$485 million over the term. The deal locks in a multi‑year mining services pipeline at one of the state’s major gold operations, supporting continuity of fleet deployment, workforce planning and site-based maintenance. Contractors and suppliers can expect sustained demand for open-pit and underground support services, consumables and rebuilds tied to Telfer’s existing mine plan.

    Metso–Valmet Flowrox pump deal: slurry circuit implications for mine engineers

    Metso has agreed to acquire Valmet’s Flowrox™ peristaltic hose pump and progressive cavity pump technologies, including associated spare parts and service capabilities, targeting abrasive and chemically aggressive slurry duties in mining and minerals processing. The deal adds positive displacement options alongside Metso’s existing slurry and submersible pump lines, enabling tighter process control in applications such as thickener underflow, filter feed and reagent dosing. For operators, the integration should simplify lifecycle support and parts standardisation across critical slurry handling circuits.
