    Veyex nylon rollers at Gudai-Darri: reliability and load lessons for mine engineers

    Veyex nylon rollers at Gudai-Darri: reliability and load lessons for mine engineers

    First reported on Australian Mining

    30 Second Briefing

    Veyex has trialled heavy-duty nylon conveyor rollers at Rio Tinto’s Gudai-Darri iron ore mine in Western Australia, where previous high-density polyethylene (HDPE) rollers were failing prematurely under high-tension loads. The case study covered two specific conveyor applications, with the nylon rollers subjected to extreme belt tensions and impact loading typical of large-scale iron ore handling. Results showed markedly improved roller durability and reduced maintenance interventions, signalling potential lifecycle and reliability gains for high-load overland and plant conveyors in similar hard rock operations.

    Technical Brief

    • Heavy-duty nylon rollers were installed on two specific Gudai-Darri conveyors operating under extreme belt tensions.
    • Previous HDPE rollers on these conveyors experienced premature structural failures when subjected to the same load regime.
    • Trials were conducted in-situ at Rio Tinto’s Gudai-Darri iron ore mine in Western Australia.

    Our Take

    Rio Tinto’s Gudai-Darri iron ore operation in Western Australia sits in the same Pilbara export chain that will be competing with new high‑grade supply from Guinea’s Simandou, so higher‑reliability components like Veyex nylon rollers help protect throughput as margins tighten on standard Pilbara ores.

    In our database, Rio Tinto features heavily across both iron ore and aluminium stories, from Gudai-Darri to the Tomago smelter power deal, signalling that incremental productivity gains at mines can have knock‑on benefits for its downstream processing and marketing portfolio.

    Suncor Cat AHS at Mildred Lake and Komatsu Mud Mode: integration notes for mine planners

    Suncor has commissioned its first Autonomous Operating Zone at Syncrude’s Mildred Lake oil sands mine, extending its autonomous haulage system deployment beyond the existing fleet of about 140 autonomous trucks already running at other Suncor sites. The new zone uses Cat AHS fleets under Suncor control (since late 2021) and is complemented by Komatsu AHS trucks at Base Plant operating with a dedicated “Mud Mode” to maintain traction and control in soft ground. For mine planners, this signals wider-scale AHS integration across multiple pits and variable ground conditions.

    Central Nevada Gold’s Mule Canyon acquisition: project and risk lens for engineers

    Central Nevada Gold has completed a US$20 million acquisition of Newmont’s past‑producing Mule Canyon mine in Nevada, targeting a prefeasibility study and key permits in H2 2027 ahead of a potential 2028 construction decision. Mule Canyon previously produced about 500,000 oz gold at an average head grade of 3.8 g/t with ~94% metallurgical recovery, and comes with a database of 2,149 drill holes totalling over 335,000 metres across six mineralised zones over 2.5 km. The company plans an IPO as early as 2027 after a 20‑hole metallurgical and infill drilling programme to upgrade inferred resources and de‑risk the project.

    Greenland Mines’ Sarfartoq licence: key project and offtake notes for mine planners

    Greenland Mines has secured government approval under the Greenland Mineral Activities Act for the indirect transfer of the Sarfartoq carbonatite complex exploration licence, clearing a key condition in its US$35 million acquisition from Neo Performance Materials, which retains offtake rights to up to 60% of future ore or concentrate. The Nd-Pr-enriched project, about 60 km from Kangerlussuaq, carries a historic NI 43-101 resource with 5.88 Mt indicated at 1.77% TREO and 2.46 Mt inferred at 1.59% TREO, based on 23,000 m of drilling. The news sent Greenland Mines’ NASDAQ-listed shares up more than 22%, giving the company a market capitalisation of US$31.4 million.
