Rio Tinto and BHP Forge New Pilbara Iron Ore Partnership
Rio Tinto and BHP have agreed to collaborate on iron ore mining in Western Australia’s Pilbara region, targeting up to 200 million tonnes from their neighbouring Yandicoogina and Yandi operations.
The initiative, outlined in two non-binding memorandums of understanding, includes joint development of Rio Tinto’s Wunbye deposit as well as the processing of ore from BHP’s Yandi Lower Channel Deposit using Rio Tinto’s wet processing facilities under mutually agreed terms.
This latest collaboration builds on a 2022 agreement between the two mining giants to extract ore from the Mungadoo Pillar, an area previously inaccessible due to shared tenure boundaries.
Matthew Holcz, CEO of Rio Tinto Iron Ore, stated: “By operating more efficiently, we can make better use of existing infrastructure to increase production with minimal additional investment.”
“Together, we will extend the life of these operations, generate further value, and continue supporting Western Australian jobs and local communities.”
The two mining giants have outlined a phased approach, starting with a conceptual study and followed by an order-of-magnitude study. A final investment decision will determine when ore extraction begins from both deposits, which is expected early next decade.
The project’s implementation depends on regulatory and joint venture approvals, as well as consultations with traditional landowners.
Tim Day, President of BHP’s WA Iron Ore asset, commented: “This is a clear demonstration of productivity in action, unlocking new opportunities by maximizing the value of our existing resources. By sharing our expertise and infrastructure, we can generate fresh value and deliver benefits for our people, partners, customers, and communities.”
Located 178 kilometres north-west of Newman in Western Australia’s Pilbara region, on the traditional lands of the Banjima people, the Yandi iron ore mine is part of a joint venture comprising BHP (85%) and Mitsui & ITOCHU (15%). Since operations began, the mine has achieved significant production milestones.
Approximately 95 kilometres north-west of Newman in East Pilbara lies Yandicoogina, another high-output mine in the region. It produces Hamersley Iron Yandi fines, which are used in steelmaking across East Asia and Southern China. Yandicoogina is also a leader in mining innovation, having pioneered the use of autonomous haul trucks.
In a separate development last December, BHP and Rio Tinto unveiled Australia’s first Cat 793 XE Early Learner battery-electric haul trucks at BHP’s Jimblebar mine. This launch marked the start of trials for Caterpillar’s battery-electric technology, positioning it as a sustainable replacement for diesel in large-scale mining. The tests will help shape the technological and operational advancements needed to cut greenhouse gas emissions at future mine sites.
Earlier this month, Rio Tinto and Glencore revealed they are in preliminary merger talks that could create the world’s largest mining group, with a combined market capitalization of nearly $207 billion.
Dalaroo Metals Uncovers District-Scale Critical Minerals System at Greenland’s Blue Lagoon
Dalaroo Metals has announced a major breakthrough from its initial 2025 exploration campaign at the wholly owned Blue Lagoon project in Greenland, revealing a district-scale system rich in critical minerals including zirconium, hafnium, and rare earth elements (REEs) across a 2.7-kilometre strike.
This represents the first sampling effort at Blue Lagoon since 1979. All 113 samples returned anomalous values, pointing to the emergence of a promising new critical metals district. Notably, concentrations exceeding 2% zirconium oxide and 40 parts per million (ppm) hafnium oxide have been identified across the entire strike length in both auger holes and sediment samples.
This points to a broad, well-mineralized target area. Hafnium is essential for next-generation microchips and semiconductors because of its high dielectric constant, which enables it to store far more electrical charge than traditional silicon dioxide-based semiconductors. Hafnium oxide boasts a dielectric constant roughly six times that of silicon dioxide and one of the highest melting points of any compound, resulting in a more than 1,000-fold reduction in electron leakage through transistors compared to silicon dioxide.
The current indicative sale price for high-purity hafnium oxide stands at A$16,297 per kilogram (US$10,924.3 per kilogram), reflecting its advanced chemical properties, rising demand in high-tech applications, and the scarcity of hafnium-bearing minerals. Additionally, the Blue Lagoon project returned high-grade rare earth element (REE) results, with elevated magnet rare earth oxides (REOs) encountered at the surface.
According to Dalaroo Metals, the presence of heavy rare earth oxides (REOs), particularly those enriched in dysprosium and terbium, underscores the potential of this previously overlooked district.
Notably, sampling at Blue Lagoon returned low uranium levels, with a maximum reading of 25 ppm triuranium octoxide. This result, which is well below Greenland’s 100 ppm uranium permitting threshold, could help simplify processing complexities.
Dalaroo Metals CEO John Morgan described the maiden results as a highly encouraging start to modern exploration at the Blue Lagoon project, saying they strongly validate the historical geochemical anomalies identified by the Greenland and Denmark Geological Survey (GEUS) that first drew the company to the area.
He noted that the scale and consistency of rare earth, niobium, and zirconium anomalism across a roughly 2.7, kilometer strike, combined with exceptionally low levels of uranium and thorium, confirm a robust and regionally extensive critical minerals system.
Although these results come from first-pass surface sampling, Morgan added that they already show grades comparable to early-stage results from several globally recognized alkaline-hosted rare earth systems in Greenland. Most importantly, he said, this work confirms that the project hosts a fertile mineral system with clear potential to grow through systematic follow-up exploration.
The initial program has successfully established the geochemical foundation to guide further exploration.
These results will be integrated with geological mapping, mineralogical assessments, and remote sensing data to refine priority target zones.
Next steps include infill sampling, trenching, and shallow drilling to investigate the origin and structural controls of the anomalous zones, as well as to assess their continuity and grade distribution.
Dalaroo Metals is fully funded following its recent capital raising at A$0.055 per share, announced in October 2025. The proceeds will support upcoming activities at the Blue Lagoon project and drilling campaigns in Côte d’Ivoire.
