    Develop to drive Waihi North access: design and geotechnical notes for mine engineers

    Develop to drive Waihi North access: design and geotechnical notes for mine engineers

    First reported on International Mining – News

    30 Second Briefing

    Develop Global has secured a A$200 million, five-year underground development contract to establish access tunnels for OceanaGold’s Waihi North Project on New Zealand’s North Island, with mobilisation scheduled for the first half of 2026. The scope centres on creating new underground access to support future gold mining adjacent to the existing Waihi operations, implying significant lateral development and ground support in complex epithermal geology. The long lead time allows detailed mine design, equipment selection and geotechnical modelling before full-scale development starts.

    Technical Brief

    • Contract value of A$200 million (~US$132 million) sets a substantial underground development budget envelope.
    • Scope is explicitly limited to establishing access tunnels, not full stoping or production activities.
    • Five-year term implies sustained development crews, long-life equipment fleets and multi-year ground support regimes.
    • Long pre-start window enables detailed geotechnical model refinement and sequencing of lateral drives and crosscuts.
    • Similar long-lead access contracts are increasingly used on complex epithermal gold projects to de-risk early capital.

    Our Take

    With work on the Waihi North Project not commencing until the first half of 2026, Develop Global Limited is effectively locking in a medium-term project pipeline in New Zealand’s North Island, which can help smooth utilisation and workforce planning between its Australian and overseas contracts.

    New Zealand has featured far less frequently than Australia or North America in our 396 Mining stories, so OceanaGold’s Waihi North work stands out as one of the relatively few North Island underground project contracts to reach this stage in our recent coverage.

    Among the 785 tag-matched ‘Projects’ and ‘Contract Award’ pieces, most contract starts are within 12–18 months of announcement, so the longer lead time here suggests a more complex approvals, design, or access schedule for Waihi North than for many comparable mining contracts in our database.

    Tapojärvi at Sotkamo Silver mine: continuity and risk notes for production engineers

    Tapojärvi has restarted as main mining contractor at Sotkamo Silver’s underground silver mine in Finland, resuming a role it previously held from 2018 to 2023 under a new agreement signed in June 2025. The contract covers full-scale production mining services, including drilling, blasting, loading and haulage in a familiar orebody and infrastructure, allowing rapid ramp-up using existing site knowledge and established operating procedures. For geotechnical and production engineers, continuity in contractor, ground control methods and equipment fleet should reduce interface risk and support stable output planning.

    STRACON’s Los Bronces tailings dam contract: lifecycle model insights for engineers

    STRACON has secured an integrated engineering, construction, financing and long-term operations and maintenance contract for the Pérez Caldera Tailings Dam at Anglo American Sur’s Los Bronces copper operation in Chile’s Lo Barnechea district. The scope combines dam design and build with funding and multi-year O&M, signalling a bundled delivery model for critical tailings infrastructure rather than separate EPC and operator contracts. For geotechnical and tailings engineers, this points to growing demand for contractors capable of lifecycle stewardship under Chile’s stringent post-Brumadinho regulatory environment.

    Metso’s third orders for Almalyk copper smelter: design and ramp-up notes for engineers

    Metso has booked the third tranche of orders for JSC Almalyk Mining and Metallurgical Complex’s copper smelter project in Uzbekistan, following equipment and project services contracts announced on 9 August 2024. The first two tranches, totalling €146 million, were booked in Q4 2024, with the latest booking covering additional core process equipment and associated services for the greenfield smelter complex. The staged order intake signals a multi-phase build-out where process design, commissioning support and long-lead items will be critical for throughput, energy performance and sulphur capture compliance.
