    WEG’s 600-motor package for Thacker Pass: design and efficiency notes for engineers

    WEG’s 600-motor package for Thacker Pass: design and efficiency notes for engineers

    First reported on International Mining – News

    30 Second Briefing

    WEG has secured a contract to supply around 600 low- and medium-voltage electric motors to Lithium Americas’ greenfield Thacker Pass lithium project in Nevada, covering key process areas from crushing and grinding to materials handling. The package will support a new lithium chemicals plant at one of the largest known lithium resources in the US, where electrified drives are central to meeting stringent emissions and energy targets. For engineers, the deal signals growing standardisation of high-efficiency motor solutions on large-scale critical minerals projects in North America.

    Technical Brief

    • Agreement covers both low-voltage and medium-voltage motor ranges for process and auxiliary plant systems.
    • Package supply from a single OEM simplifies spares strategy, motor control centre design and drive standardisation.
    • Centralised motor specification should streamline VSD selection, harmonic studies and power quality management on the new plant.
    • Using one motor family across unit operations can reduce engineering hours for layouts, foundations and cable sizing.

    Our Take

    Several recent pieces link Lithium Americas’ Nevada assets with Indigenous rights and stewardship concerns, suggesting that visible investments in efficient electric equipment at Thacker Pass may be framed not just as operational choices but as part of the company’s social licence narrative in the United States.

    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’s 42‑month Telfer Gold Mine extension: planning notes for project teams

    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.
