Autonomous copper refining at Olympic Dam

Sandvik has launched its next-generation automated development drill rig, the DD423i, which offers 34.5% more drilling coverage than legacy models.Delivering 48% improved crosscut performance, the DD423i introduces new SB75i booms with double rollovers for superior reach in confined spaces, such as room and pillar applications. Automatic boom movements and integrated boom collision avoidance provide faster, safer and more precise drilling cycles.Sandvik development drills product manager Simon Morrissey says the introduction of the DD423i is an important milestone for Sandvik.“The DD422i set the benchmark for development drilling in 2015 and its success over the past decade has shaped the industry,” he said.“With the DD423i, we honour that legacy while delivering a future ready drill designed for even higher performance, automation and safety.”In field testing in Boliden, in the Skellefteå region of Sweden, the DD423i achieved over 95% machine availability, highlighting Sandvik’s commitment to robust and dependable equipment.“The Skellefteå region is known for its extremely hard and abrasive geological conditions,” Mr Morrissey said.“It is one of the toughest areas for rock drilling in Scandinavia and therefore provided the ideal testing conditions for the DD423i.”The redesigned cabin on the DD423i delivers a step forward in operator safety and comfort, offering 55% increased visibility, lower noise levels and improved dust control.Enhanced serviceability with easy access to key components supports quicker maintenance and reduces downtime while the advanced drilling control system provides fast and accurate performance with intuitive operation for all skill levels.The DD423i is fully compatible with Sandvik digital mining solutions, enabling a connected, data driven approach to development drilling.

BHP backs next wave of exploration and technology talent BHP (ASX: BHP) has selected 10 junior exploration and technology companies for its 2026 Xplor program, marking the largest cohort since the program began.Now in its fourth year of operation, the Xplor program reflects a more connected approach to early-stage exploration, where geological insight, data and emerging technologies increasingly intersect — with collaboration across disciplines central to how discovery evolves.As exploration moves into more remote and geologically complex environments, this intersection of expertise is opening up new possibilities for how mineral systems are understood, tested, and advanced at the earliest stages.BHP Group exploration officer Tim O’Connor says exploration is evolving quickly.“New tools, better data and different ways of working are changing how early-stage ideas are tested and refined,” he said.“This cohort reflects that shift, bringing together explorers and technology developers who are approaching discovery in thoughtful and practical ways. Xplor gives us a valuable opportunity to learn alongside them and explore what discovery could look like in the future.”The cohort was selected based on the strength of their ideas, technical capability and potential to contribute to the long-term supply of future-facing commodities.Each company will receive an equity-free grant of about $717,000 , along with structured learning, mentoring and access to BHP specialists across exploration, technology and commercial functions.BHP Xplor head Marley Palin says the 2026 cohort reflects how broad and dynamic early-stage discovery has become.“We’re seeing exciting ideas emerge across exploration, data and technology, often at the same time and in the same places,” she said.“Bringing these teams together through Xplor creates a unique environment for collaboration, learning and experimentation — we’re looking forward to what this group will explore over the coming months.”Xplor 2026’s successful applicants FrontierX FrontierX is an early-stage uranium exploration company in Canada, formed by two BHP Xplor Year One alumni, Fabian Baker and Andrew Tunningley.

Rehabilitation at Ranger uranium mine continues The Federal Government has issued a new rehabilitation authority to Energy Resources Australia (ERA) to continue rehabilitation activities at Ranger uranium mine in the Northern Territory. The authority will allow ERA, a subsidiary of Rio Tinto (ASX: RIO), to progress a staged rehabilitation strategy that focuses upon adherence to objectives as stated in the authorisation to operate to allow the site to be returned to the Mirarr Traditional Owners. This strategy will be achieved through the application of best practice and the use of technology within a risk-based framework. ERA’s long-term vision is to return the disturbed area to a viable ecosystem in line with its obligations to its stakeholders and regulators and the expectations of the community. Federal Resources Minister Madeleine King comments on the authority. “This new authority means that ERA will be able to continue with its obligation to restore Ranger uranium mine to a condition similar to the surrounding Kakadu National Park,” she said. Mirrar Traditional Owners have worked closely with the Northern Land Council and ERA on a new land access agreement. Indigenous Australians Minister Malarndirri McCarthy approved the agreement under the Aboriginal Land Rights Act (Northern Territory). “I thank the Mirarr Traditional Owners, Gundjeihmi Aboriginal Corporation, Northern Land Council, ERA and Rio Tinto for their collaborative efforts in establishing this new authority and land access agreement,” she said. “We want to see rehabilitation completed and for the land to be returned to the Mirarr Traditional Owners.” Rehabilitation and closure planning began soon after the Ranger mine began producing uranium oxide in 1981.  Operations at Ranger ceased after ERA failed to secure permission from the Mirarr Traditional Owners and the Gundjeihmi Aboriginal Corporation to continue mining the sire.  ERA increased its estimated rehabilitation provision to $830m in 2019, a major increase from the $526m estimate recorded in 2017. 

WA’s next generation of mining safety leaders gets boost The Mental Awareness, Respect and Safety (MARS) Centre at Edith Cowan University (ECU), with support from the WA Government, is offering a number of fully funded scholarships for the Graduate Certificate of Leadership in Mining Workplace Safety.The program is designed to develop leaders who can effectively manage psychosocial risks, support a culture of safety and respect, and drive evidence-based wellbeing and safety practices across WA’s mining organisations.The course consists of three consecutive units delivered in an intensive block. It is offered flexibly online to accommodate the demanding and variable work schedules of the mining workforce, with regular opportunities for online engagement and support.To be eligible for the scholarship, applicants must currently be working within the WA mining sector and will need to submit a course application and receive a course offer.MARS Centre deputy director Associate Professor Kate Blackwood says that as part of the applicant review process, consideration would be given to the applicant's motivation for undertaking the program, their plans for applying the knowledge gained and the steps they have taken to prepare for success."We're looking for applicants who are motivated to turn learning into action, leaders who want to strengthen safety, respect and wellbeing across their teams and organisations," she said."This program is designed to equip mining professionals with practical, evidence-based skills they can apply immediately, while balancing the realities of working in a demanding industry."The course is set to run between March 9 to July 19.
