    Pilgangoora P680–P1000 expansion: design and earthworks outlook for engineers

    Pilgangoora P680–P1000 expansion: design and earthworks outlook for engineers

    First reported on Australian Mining

    30 Second Briefing

    Pilbara Minerals used its AGM to detail expansion at the Pilgangoora lithium operation in Western Australia, where the P680 project is lifting nameplate capacity from about 580,000 tonnes per annum to roughly 680,000 tonnes of spodumene concentrate. The company is progressing early works on the larger P1000 expansion, targeting around 1 million tonnes per annum through additional crushing, grinding and flotation capacity and associated power and water upgrades. For geotechnical and civil contractors, the staged debottlenecking and plant footprint growth signal sustained demand for earthworks, tailings storage expansion and haul road upgrades.

    Technical Brief

    • Additional crushing, grinding and flotation trains will demand new foundations, structural steelwork and conveyor corridors.
    • Water system changes will likely involve new pipelines, storage tanks and pump station earthworks within a constrained footprint.
    • Higher concentrate output will drive incremental tailings storage facility lifts and embankment raises under ongoing operations.
    • Haulage growth from expanded pits to plant suggests progressive haul road widening, regrading and pavement strengthening.

    Our Take

    Lithium pieces in our mining coverage have increasingly centred on Australian operations, so further expansion or contract activity at Pilgangoora reinforces Western Australia’s role as the core hard‑rock lithium supply base rather than newer African projects.

    For Pilbara Minerals, additional project or contract milestones at the Pilgangoora operation signal that, despite volatile lithium prices in 2024–25, established Australian producers are still progressing site-level work rather than shelving brownfield opportunities.

    Among the 125 tag‑matched ‘Projects’ and ‘Contract Award’ items in our database, lithium projects like Pilgangoora tend to move faster from award to execution than bulk commodity projects, which likely benefits PLS when timing market upswings.

    Focus Graphite’s Lac Tetepisca resource: capex and pit geometry notes for engineers

    Focus Graphite’s Lac Tetepisca project in central Quebec now hosts 14.7 million tonnes of contained graphite at 10.2% Cg, an 86% increase over its 2022 resource, ranking fifth globally and second in North America by contained tonnes. The updated estimate, based on 26,095 metres of drilling in 150 holes, includes 12.3 million tonnes contained graphite in measured and indicated resources (120.1 million tonnes at 10.27% Cg) plus 2.3 million tonnes inferred (24.1 million tonnes at 9.88% Cg). Grades above 10% Cg, open-pit geometry with favourable strip ratios, low-cost Quebec hydropower and planned >99.9% purity processing underpin analyst views that Focus trades at an 81% discount to peers.

    Freeport’s delayed Grasberg restart to 2028: production and risk notes for mine engineers

    Freeport Indonesia has pushed back Grasberg’s full production restart to early 2028, after a September mudflow in the Grasberg Block Cave killed seven workers, halted underground mining and triggered force majeure on shipments. The complex, which previously supplied about 3% of global copper (1.7 billion lb/year) and 1.4 million oz/year of gold, is currently operating at roughly 40–50% capacity, with copper output for 2026 now guided at 700 million lb versus a prior 1‑billion‑lb target. Ramp-up targets have been reset to 65% capacity in H2 2026 and 80% by mid‑2027, as additional logistics and ore-handling infrastructure work proceeds.

    San Lorenzo Chile gold assays: porphyry potential and drilling cues for mine planners

    San Lorenzo Gold’s Salvadora project in Chile’s Atacama region returned strong gold intercepts at the Arco de Oro target, with hole SAL-10-25 cutting 102 m at 1.33 g/t Au from 153 m (including 13 m at 2.21 g/t), and nearby SAL-09-25 yielding 59 m at 1.07 g/t Au from 238 m (including 11 m at 3.78 g/t). Exploration VP Terence Walker interprets the results as the upper levels of a gold‑rich porphyry Cu‑Au system, open in all directions and warranting immediate follow‑up drilling. The 90+ sq. km Salvadora property lies about 15 km from Codelco’s El Salvador mine, and a C$20 million March placement is funding ongoing step‑out drilling across five porphyry and epithermal targets.
