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. 

The Queensland Government is investing $500,000 to support the women in resources: empowering development (WIRED) pilot program.The program, delivered by the Queensland Resources Council (QRC), focuses on upskilling and reskilling women into advanced site-based roles to strengthen Queensland’s resources workforce and support more women into higher-skilled operator and technician roles across the state.The WIRED program will deliver targeted training for roles including machinery operators, plant technicians and site supervisors while supporting women transitioning into higher-level operator and technician roles.Early engagement across the sector has commenced, with the program expected to launch in mid-2026.Queensland Finance, Trade, Employment and Training Minister Ros Bates says the investment is about backing a sector that drives jobs and regional growth.“We are backing one of Queensland’s economic powerhouses by delivering the skilled workforce it needs to keep growing,” she said.“We are making sure women have clear, practical pathways into higher-skilled, higher-paid roles on site.“When you expand opportunities in a $44b industry, you strengthen the entire economy.”In the Australian resources sector, women now represent a larger portion of roles but there is still major room for growth with the percentage of women holding roles in the mining sector fluctuating between 22 – 23% since 2024, according to the Federal Government’s Workplace Gender Equality Agency (WGEA).QRC chief executive Janette Hewson says WIRED is about enabling and retaining women in technician and operator roles to move into site-based leadership roles.“Our vision is an industry where women with technical skills have a clear pathway to more senior roles and can thrive in these roles long-term,” she said.“By supporting women who are working onsite, we create a workplace culture where everyone can thrive.”

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.

Autonomous copper refining at Olympic Dam BHP (ASX: BHP) is driving safety in copper refining at its Olympic Dam refinery in South Australia with a fully enclosed and automated robotic cathode stripping machine.Cathode stripping is a crucial step in the copper refining process, involving the removal of thin sheets of nearly pure copper (known as cathode) from large metal plates after refining.BHP’s original cathode stripping machine required frequent manual intervention, exposing operators to potential hazards including crush injuries, line-of-fire incidents and physical strain. Beyond safety concerns, the physically demanding nature of the work also limited participation, hampering efforts to build a more inclusive workforce.To address these challenges, a team of frontline workers and engineers from the refinery collaborated with project partners to develop and implement a safer and more inclusive approach.The team developed a fully enclosed and automated robotic cathode stripping machine, which uses precision automation to strip and process cathodes autonomously, to eliminate operator exposure to potential hazardous conditions — improving equipment reliability and reducing downtime caused by copper jams.Introducing an automated solution has also expanded the pool of candidates for operator roles, contributing to making Olympic Dam operations more inclusive, with women being strongly represented among qualified operators.The project won the Safety, Security and Emergency Management category at BHP’s 2025 Health, Safety, Environment and Community Awards for its reflection of the company’s culture of continuous improvement and collaboration — where frontline teams, engineers and partners come together to deliver solutions that make a tangible difference to how the company operates.
