    Western Australian gold producers: Q1 mine performance and project notes for engineers

    First reported on Australian Mining

    30 Second Briefing

    Western Australian gold producers reported stronger March-quarter output, with established operations such as Kalgoorlie and Boddington lifting mill throughput and improving head grades despite persistent labour and energy cost pressures. Developers advanced expansion projects including new open-pit cutbacks and underground declines, alongside incremental plant upgrades such as additional leach capacity and improved gravity circuits. Exploration drilling around existing pits and along greenstone belt extensions continued to grow resource potential, extending mine lives and supporting long-term planning for tailings storage and haulage infrastructure.

    Technical Brief

    • Producers detailed mine-specific sequencing changes, such as bringing higher-grade stopes online earlier in the quarter.
    • Several operators flagged additional open-pit cutbacks requiring updated geotechnical slope designs and revised waste-dump footprints.
    • Underground expansions involved new declines and level development, implying increased demand for ground support and ventilation upgrades.
    • Plant optimisation work referenced circuit debottlenecking rather than major greenfield builds, limiting capital intensity per ounce.
    • Developers tied exploration success directly to revised life-of-mine schedules, affecting timing of new tailings storage cells.
    • Cost commentary focused on labour and power tariffs, with no major changes to mining method selection.
    • For similar Western Australian goldfields, the quarter’s activity suggests continued preference for brownfield expansions over standalone greenfields.

    Our Take

    Western Australian gold sits within 378 gold‑keyword pieces in our database, but relatively few of those focus on a single state, signalling that WA producers are still the main reference point for Australian gold performance benchmarks.

    Several recent Western Australian items in our coverage, such as Fortescue’s remote‑camp connectivity rollout, highlight ongoing investment in FIFO camp infrastructure that gold operators in the state can typically leverage without bearing full greenfield social‑infrastructure costs.

    Schlam installation kit programme: interface control and uptime gains for mines

    Schlam has launched a new in-house engineered installation kit programme for mining truck bodies and excavator buckets, giving sites a standardised, end-to-end package covering attachment supply and fit-out. Developed under a three-year product development effort, the kits are designed to integrate with Schlam’s load and haul attachments, reducing the need for bespoke on-site fabrication and ad hoc hardware selection. For maintenance and asset teams, this points to more predictable installation times, simplified spares management and tighter control of attachment interface geometry.

    Integra’s 74% reserve lift at Florida Canyon: project economics for mine planners

    Integra Resources’ updated feasibility study for the Florida Canyon heap leach mine in Nevada lifts proven and probable reserves 74% to 1.1 million oz at 0.31 g/t, raises planned output to 82,000 oz gold per year over eight years, and boosts the 5% NPV to US$601 million using a US$4,200/oz price. All-in sustaining costs climb 43% to US$2,331/oz with recovery steady at 62%, but post-tax free cash flow is projected at US$800 million, averaging US$90 million annually. Integra is drilling 42,500 metres around the existing operation to grow resources and fund its DeLamar gold-silver project in Idaho.

    DRC critical minerals strategy: price-setting and supply risks for mine planners

    Democratic Republic of Congo has shifted from price-taker to price-setter in cobalt by imposing ARECOMS-managed export quotas and planning state stockpiles of cobalt, coltan and germanium. Cobalt prices have climbed from about $21,000/t in early 2025 to just over $56,000/t, with Kinshasa forecasting $2.3 billion in fiscal revenues this year versus an estimated $617 million without intervention. Advisory input from Vectus Global and new investment moves such as Virtus Minerals’ acquisition of Chemaf signal tighter supply discipline and a push for higher value-added partnerships.
