    Minerals 260 A$410M Bullabulling finance: project economics for mine planners

    First reported on MINING.com

    30 Second Briefing

    Minerals 260 has secured A$410 million in bank debt from ANZ, National Australia Bank and Société Générale for the Bullabulling gold project in Western Australia, with no hedging requirement and interest set at under 3% above the bank bill swap bid rate. Combined with Franco-Nevada’s US$170 million royalty funding and US$30 million equity, the package is intended to fund a 5 Mtpa plant and development to first production, targeting about 150,000 oz gold per year from 2028. July’s resource stands at 140 Mt indicated at 0.98 g/t and 51 Mt inferred at 1.0 g/t, supporting a 19-year mine life and long-term pit and tailings planning near Kalgoorlie.

    Technical Brief

    • ANZ, NAB and Société Générale split A$335M project finance plus A$75M working capital facilities.
    • Project loan tenor is seven years, with a separate four‑year working capital facility.
    • Interest during construction is capitalised, increasing debt at commissioning but easing early cashflow pressure.
    • Franco-Nevada’s gross royalty on Bullabulling rises to 3.9%, up from 2.45%, under the September deal.
    • July resource: 140 Mt indicated at 0.98 g/t Au (4.4 Moz) plus 51 Mt inferred at 1.0 g/t (1.7 Moz).
    • Prefeasibility envisages a 19‑year operating life, with plant layout allowing future throughput expansion beyond 5 Mtpa.

    Our Take

    Bullabulling’s low head grade (about 1g/t) combined with a 5Mtpa plant and 19‑year life puts Minerals 260 into the same long‑life, bulk‑tonnage camp as several other Western Australian gold plays in our database, where cost control and strip ratio management tend to be more decisive than incremental grade gains.

    The step‑change in Franco‑Nevada’s gross royalty to 3.9% on Bullabulling, alongside its aggregate $420 million backing, signals that royalty capital is increasingly competitive with bank debt for large Australian gold builds, something only a handful of gold‑price pieces in our coverage have highlighted explicitly.

    Earlier related drilling reports from 2025–2026 on Bullabulling show progressively higher‑grade intercepts, suggesting upside to the current 6.1–6.2Moz resource base that could improve project economics over the seven‑year loan term if those zones can be converted into reserves and brought into early mine schedules.

    Brightstar’s 305m gold hit at Two Mile Hill: bulk underground potential for engineers

    Brightstar Resources has reported its largest Sandstone result at the Two Mile Hill deposit in WA, intersecting 305m at 2.66g/t gold from 503m depth in diamond hole TMHDD26005. The interval contains multiple high-grade zones, including 4.1m at 26.1g/t, 5.5m at 25.2g/t and 4m at higher-grade material within the broader mineralised envelope. The scale and continuity of this intercept materially upgrade the grade-times-width profile of Two Mile Hill, supporting potential for bulk underground mining scenarios and further deep drilling.

    BHP record WA community spend: procurement signals for mining contractors

    BHP has reported a record $1.1 billion in community expenditure across Western Australia for FY2026, including $627 million in procurement from Indigenous and Traditional Owner businesses. The miner’s 2026 Western Australia Community Development Report also details more than $850 million in payments to local suppliers, councils and community partners, signalling a heavy regional spend alongside its iron ore and nickel operations. For contractors and service providers, the scale of Indigenous and local sourcing points to strong demand for WA-based capability and joint ventures.

    AIC Mines’ 18.7Mt Mt Cuthbert copper project: planning signals for mine engineers

    AIC Mines has closed a $70 million acquisition of Materra Metals, securing 100 per cent ownership of the Mt Cuthbert copper project in north‑west Queensland and adding 18.7 million tonnes of copper resources to its portfolio. The company plans a major drilling program in 2027, signalling a shift from resource consolidation to definition drilling and potential mine planning at Mt Cuthbert. For geotechnical and mine planners, the deal points to upcoming demand for pit design, hydrogeology, and infrastructure studies in a historically underdeveloped copper district.
