    Gold Royalty’s $70M BHP Brazil mine deal: cash-flow and grade lens for engineers

    First reported on MINING.com

    30 Second Briefing

    Gold Royalty has agreed to buy BlackRock World Mining Trust’s royalty over BHP’s Pedra Branca copper-gold mine in Pará, Brazil, for $70 million cash, adding a 25% net smelter return on gold and 2% NSR on copper and other products across the Pedra Branca East and West deposits. The royalty generated about $7.9 million over the 12 months to 30 June, equivalent to roughly 2,800 gold-equivalent ounces at an average gold price of $2,811/oz, from ore grading 1.41–1.68% copper and 0.40–0.47 g/t gold. Gold Royalty will fully fund the deal via a $70 million bought equity financing of 17.5 million shares at $4.00, taking its portfolio to eight cash-flowing assets and over 250 royalty and streaming interests.

    Technical Brief

    • Pedra Branca forms part of the Carajás East copper operation in Água Azul do Norte, Pará, Brazil.
    • OZ Minerals commissioned the Pedra Branca East underground mine in 2020 and achieved full production by 2022.
    • BHP acquired Pedra Branca via its 2023 takeover of OZ Minerals and has since extended mine life.
    • June 2025 reporting states 2.4 Mt measured at 1.68% Cu and 0.47 g/t Au.
    • Indicated resources add 12 Mt at 1.41% Cu and 0.40 g/t Au, supporting sustained mill feed.
    • Equity financing for the royalty purchase involves 17.5 million new GROY shares at $4.00 per share.

    Our Take

    With Pedra Branca’s measured and indicated copper grades of around 1.4–1.7% Cu, this BHP-operated asset sits at the higher-grade end of the copper stories in our mining database, which typically feature sub‑1% Cu for new Latin American developments.

    The $7.9 million royalty expense over 12 months versus a $70 million purchase price implies Gold Royalty is paying a relatively short multiple of recent cash flow, signalling confidence in both mine life extension at Pedra Branca and further resource conversion in the Carajás district.

    Adding a copper‑gold royalty in Pará gives Gold Royalty exposure to a region that appears less frequently in our 196‑story mining corpus than Andean copper belts, suggesting the company is deliberately diversifying jurisdictional risk away from more heavily scrutinised permitting environments.

    Mastermyne Tahmoor mine services award: contract structure and risks for engineers

    Mastermyne Group has secured a new mining services contract with GMT Mining Pty Ltd for the restart and ongoing operation of the Tahmoor underground coal mine in New South Wales. The mine was recently acquired by a consortium of M Group – Mastermyne’s largest shareholder – and Golden Energy and Resources (GEAR), and will be operated by GM3. The deal signals a structured restart pathway for Tahmoor, with clear separation between ownership (M Group/GEAR), operations (GM3) and contracted underground services (Mastermyne).

    FLS Chile copper mine order: HPGR–ball mill flowsheet insights for process engineers

    FLSmidth has secured a major order in Chile to supply core grinding technologies for a new copper grinding line, including high-pressure grinding rolls (HPGR) and a ball mill. The package follows earlier collaborative engineering work on the mine’s expansion and is positioned as the next phase of a long-term process plant partnership with the unnamed customer. For process engineers, the HPGR–ball mill configuration signals continued confidence in energy-efficient comminution flowsheets for large-scale copper operations in the Andean region.

    IMARC 2026: critical minerals, automation and electrification insights for engineers

    Australia’s Resources Minister Madeleine King is using IMARC 2026 in Sydney to position the country as a central hub in global critical minerals supply chains, with a strong focus on lithium, nickel and rare earths projects. The event is expected to draw thousands of delegates and several hundred exhibitors across exploration, mine automation and downstream processing, including OEMs showcasing autonomous haulage fleets and OEM-agnostic fleet management systems. For engineers, the agenda signals continued investment in electrified mobile equipment, high-throughput ore sorting and low-carbon refining technologies.
