    Regis gold exploration at Duketon and Tropicana: mine life and reserve lens for planners

    Regis gold exploration at Duketon and Tropicana: mine life and reserve lens for planners

    First reported on Australian Mining

    30 Second Briefing

    Regis Resources is accelerating gold exploration across its Duketon, McPhillamys and Tropicana assets, with first-half drilling aimed at both underground and open pit growth projects. Priority work includes step-out and infill drilling to tighten geological models, test depth extensions beneath existing pits and refine resource confidence around known lodes. The programme is geared to convert near-mine targets into longer-term development options, potentially extending mine life and supporting future reserve upgrades across the three operations.

    Technical Brief

    • Duketon exploration is centred on near-pit targets around existing open pits and underground portals.
    • At Tropicana, drilling is being directed along strike of current underground lodes to test continuity.
    • McPhillamys work is skewed to defining satellite and regional targets that could supplement the planned open pit.
    • Step-out drilling at depth beneath current workings is explicitly aimed at identifying new underground mining fronts.
    • Infill holes are being prioritised where current data spacing constrains pit shell optimisation and stope design.
    • Regis is sequencing drilling to feed directly into updated geological models before the next reserve and resource statements.

    Our Take

    Recent coverage of Regis Resources shows a sequence of moves that link this Duketon and Tropicana exploration push with a 120 per cent ore reserve increase and brownfields growth strategy across its Western Australian gold portfolio, signalling a deliberate effort to extend mine life rather than chase new greenfields camps.

    The revived McPhillamys project in New South Wales, with its reinstated 1.89‑million‑ounce reserve and filtered tailings concept, gives Regis a second growth front outside Western Australia, which can balance any grade or permitting risk that emerges as Duketon and Tropicana are drilled deeper.

    A$180 million of ongoing underground work at Duketon under the Barminco alliance, combined with the roughly $1 billion liquidity buffer reported from Duketon and Tropicana cash flow, suggests Regis has both the technical and financial capacity to rapidly convert successful exploration at these gold assets into mine plan updates and production uplift.

    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.
