    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.

    Suncor Cat AHS at Mildred Lake and Komatsu Mud Mode: integration notes for mine planners

    Suncor has commissioned its first Autonomous Operating Zone at Syncrude’s Mildred Lake oil sands mine, extending its autonomous haulage system deployment beyond the existing fleet of about 140 autonomous trucks already running at other Suncor sites. The new zone uses Cat AHS fleets under Suncor control (since late 2021) and is complemented by Komatsu AHS trucks at Base Plant operating with a dedicated “Mud Mode” to maintain traction and control in soft ground. For mine planners, this signals wider-scale AHS integration across multiple pits and variable ground conditions.

    Central Nevada Gold’s Mule Canyon acquisition: project and risk lens for engineers

    Central Nevada Gold has completed a US$20 million acquisition of Newmont’s past‑producing Mule Canyon mine in Nevada, targeting a prefeasibility study and key permits in H2 2027 ahead of a potential 2028 construction decision. Mule Canyon previously produced about 500,000 oz gold at an average head grade of 3.8 g/t with ~94% metallurgical recovery, and comes with a database of 2,149 drill holes totalling over 335,000 metres across six mineralised zones over 2.5 km. The company plans an IPO as early as 2027 after a 20‑hole metallurgical and infill drilling programme to upgrade inferred resources and de‑risk the project.

    Greenland Mines’ Sarfartoq licence: key project and offtake notes for mine planners

    Greenland Mines has secured government approval under the Greenland Mineral Activities Act for the indirect transfer of the Sarfartoq carbonatite complex exploration licence, clearing a key condition in its US$35 million acquisition from Neo Performance Materials, which retains offtake rights to up to 60% of future ore or concentrate. The Nd-Pr-enriched project, about 60 km from Kangerlussuaq, carries a historic NI 43-101 resource with 5.88 Mt indicated at 1.77% TREO and 2.46 Mt inferred at 1.59% TREO, based on 23,000 m of drilling. The news sent Greenland Mines’ NASDAQ-listed shares up more than 22%, giving the company a market capitalisation of US$31.4 million.
