    Thiess Global Summit at Mulgarrie AHS trial: retrofit autonomy lens for mine planners

    First reported on International Mining – News

    30 Second Briefing

    Thiess, together with MACA and RTL Mining and Earthworks, has visited Norton Gold Fields’ Mulgarrie operation near Kalgoorlie, where an autonomous haulage system (AHS) trial using EACON Mining Technology’s retrofitted trucks is under way. The trial, run with Norton Gold Fields (owned by Zijin Mining Group), is testing retrofit autonomy on an existing truck fleet rather than deploying factory-built autonomous units. For mine operators, successful validation would support lower‑capex conversion of conventional haul trucks to AHS across similar Australian gold and bulk operations.

    Technical Brief

    • Thiess, MACA and RTL leadership visited Mulgarrie as part of the Thiess Global Summit programme.

    Our Take

    The related December 2025 and January 2026 pieces on EACON’s Komatsu HD1500 at Norton Gold Fields’ Mulgarrie site show this gold operation in Western Australia moving quickly from initial autonomous test cycles to fully driverless runs, signalling that Thiess is using Mulgarrie as a live proving ground rather than a small pilot.

    Across our mining database, Thiess appears frequently in higher-complexity project work (e.g. the Eva copper and Mount Pleasant contracts), so its presence at a retrofitted AHS gold site in Kalgoorlie suggests contractors are preparing to bundle autonomy capability into broader mine development and operations offerings.

    With Zijin Mining Group linked to Norton Gold Fields in the related coverage, successful AHS deployment at Mulgarrie could give EACON and Thiess a reference case that is exportable to other Zijin-owned gold assets, particularly where haulage modernisation is a near-term bottleneck.

    Next generation of mining in Australia: integrated digital systems for engineers

    Artificial intelligence, automation, connected data and cybersecurity are converging in Australian mining operations, moving beyond isolated pilots towards integrated digital ecosystems across pits, plants and rail. Examples include autonomous haulage fleets linked to fleet management systems, AI-driven drill and blast design, and digital twins fed by real-time sensor data from crushers, conveyors and processing circuits. The direction of travel is towards interoperable platforms rather than single-vendor silos, with implications for data architecture, control system integration and cyber-resilience in brownfield and greenfield projects.

    Victory Metals’ North Stanmore rare earths: defence offtake lens for miners

    Victory Metals is pitching its North Stanmore heavy rare earth project in Western Australia to the US defence sector at the Defense Industrial Base Accelerator (DIBX) 2026 in Philadelphia, with chief executive Brendan Clark seeking to embed the asset in allied critical minerals supply chains. The company is targeting defence-grade demand for heavy rare earths used in permanent magnets for missiles, radars and other high-specification systems, positioning North Stanmore as a non-Chinese source. For miners and processors, the move signals growing scrutiny on provenance, offtake security and processing routes suitable for defence qualification.

    Silver Mines board reshaped at Bowdens: DFS execution signals for project engineers

    Silver Mines has reshaped its board at the Bowdens Silver Project in New South Wales, appointing mining executive Nicole Brook and former federal resources minister Joel Fitzgibbon as independent non-executive directors following completion of the project’s Definitive Feasibility Study (DFS). The DFS locks in the technical and economic case for what is billed as Australia’s largest undeveloped silver deposit, giving lenders and regulators a clearer basis for approvals and project finance. For engineers, the move signals progression from study to execution planning, with board-level backing for detailed design, procurement and construction decisions.
