BHP backs next wave of exploration and technology talent

Metso achieves certification ahead of schedule Metso has achieved the internationally recognised ISO 27001 certification for its information security management system (ISMS), marking a significant milestone in the company’s cybersecurity capabilities.The certification was awarded to Metso IT ahead of the original Q2 CY2026 target, demonstrating the company’s strong commitment to protecting information assets and meeting rising customer and regulatory expectations.ISO 27001 provides a globally accepted framework for managing information security risks and ensuring the confidentiality, integrity and availability of data. By meeting the standard, Metso confirms that its security processes and controls are systematically designed, implemented and continuously improved to meet international best practices.Metso IT risk and compliance director Janne Mennala says achieving this certification signals credibility and discipline, but it is only the beginning of a continuous improvement journey.“With our ISMS now aligned with ISO 27001, our security practices are more transparent and easier to demonstrate to partners and customers,” he said.The certification covers Metso IT’s global functions and strengthens the basis for further security development within the company’s business segments.Throughout the certification process, Metso worked in close partnership with Cyberismo, a Finnish cybersecurity company and long-standing expert partner. Their support has been instrumental in ensuring that Metso’s ISMS aligns with industry best practices and future requirements.“We are truly proud of what we have achieved together. The success confirmed that we have been moving in the right direction for much longer than this project alone,” said Mr Mennala.

Brownfield expansion overtakes greenfield development Brownfield development has intensified in recent years and — despite global mineral demand rising faster than supply growth — new mine commissioning has slowed.A new study, led by researchers from The University of Queensland’s Sustainable Minerals Institute (SMI), provides a snapshot of the potential social and environmental costs of this growing trend and the implications for sustainable development.As worldwide demand for minerals surges, mining companies have been doubling down on investment into brownfield development, with the study showing increasing investment in brownfield mining over greenfield sites.This is particularly prevalent in minerals crucial to renewable energy technologies, transport, digital and defence infrastructure — most notably, copper and lithium.Growing demand reflects the rapid uptake of decarbonisation technologies. Such technologies are considered minerally intense. Electric vehicles require about six times the mineral inputs of conventional cars and onshore wind turbines require significantly more minerals than gas-fired plants of similar capacity.While historical mineral production has broadly kept pace with rising demand, projections show demand growing more sharply in the future. For copper and lithium, projected primary supply from announced mining projects will fall short of demand by 2035 under current policy settings, according to the IEA.To maintain supply, the Federal and State Governments continue to reform policy to support mineral exploration and major project development.Last year, the Federal Government proposed amendments to the Environment Protection and Biodiversity Conservation (EPBC) Act to speed up decision making processes, deliver faster turn arounds and improve bilateral agreements with states and remove duplication for the assessment and approval of projects.Despite growing efforts to streamline approvals for greenfield sites, the global interval between discovery and production has lengthened, now averaging 15.7 years, according to S&P Global.Expansion of brownfield explorationExpanding existing operations has been a cornerstone of many miners’ business models as companies can leverage existing infrastructure and sunk capital.SMI Centre for Social Responsibility in Mining director and lead author Professor Deanna Kemp says 60% of major company exploration budgets in 2024 were at or near existing mines, more than double 2016 levels.“Brownfield mining is an appealing option for mining companies because it maintains production, offers a stronger return on investment, with fewer financial and regulatory risks than establishing new ‘greenfield’ mines, while also deferring the significant costs of closure and rehabilitation,” she said.A snapshot of 366 brownfield sites across 58 countries and16 minerals including critical minerals including cobalt, copper and platinum were used by researchers to understand their social and environmental contexts.The study found that number of new copper mines peaked around 2015, in the early 2000s for iron ore, around 2010–2012 for nickel, and around 2012–2014 for gold. However, since these peaks, and the subsequent decline in the numbers of new mines, production has continued to rise.The research revealed the inverse relationship of rising production with fewer new mines and where output is increasingly concentrated in large, long-life operations for copper, iron ore and nickel — with brownfield capital expenditure being dominated by copper, constituting just under half the total spend.Between 2010 and 2024, expansion dominated industry spending in Australia while other parts of the world saw a gradual increase over the period.According to the researchers, about 80% of the brownfield sites that were studied are located in high risk jurisdictions, facing challenges including water scarcity, poor governance and low press freedom.Regulation of mine expansionThe 2020 destruction of Juukan Gorge, a 47,000-year-old Indigenous cultural heritage site, as part of a legal expansion of an iron ore mine illustrates that brownfield projects can have real and significant costs.“Once a mine has been approved and permitted, expansion is typically a business-as-usual part of developing a mine, even when that expansion changes the original risk of social and environmental impact,” Professor Kemp said.“Brownfield expansion often unfolds incrementally over time, with less public scrutiny: the risk factors involved in each mine site are unique and no-one has really been looking at the scale of growth brownfield mining globally.”The researchers found that more than half of their samples were in locations with multiple complex risk factors like social conflict, fragile ecosystems and weak governance, making it harder for governments and affected communities to respond to the risks presented by these expansions.Mine approval and regulatory standards are usually heavily focused on the beginning of operations by assessing risks and impacts before a mine opens. More recently, there has been an increasing focus on responsible mine closure and land rehabilitation. Both aspects are important, but the research highlights that the way mines expand and extend is becoming more important.“In the ‘middle’ of a mine’s lifespan — when the mine is active there is often less oversight or public focus — changes tend to be regulated, step by step, but the impacts of these expanded operations add up over time,” Professor Kemp said.“More research is needed to quantify the sheer scale of this trend towards greater reliance on brownfield sites, and their cumulative, long-term social and environmental effects.”CSRM research fellow and co-author Dr Julia Loginova says that given that capital is flowing into brownfields, regulatory and academic scrutiny should be moving there as well.“Brownfield sites may be the fastest and economically attractive way to meet rising mineral demand, but it is important to anticipate and manage pressures and long-term liabilities, that’s why further research in this space is very much needed, because there is still a fundamental knowledge gap,” she said.“There is a significant opportunity for interdisciplinary research to better understand scale and impacts, to support improved practice in the sector.”

WA Government supports renewables growth Ngarluma Aboriginal Corporation (NAC) are collaborating with Perdaman and the WA Government to establish a 50MW solar farm at the Ngarluma green energy park on NAC's native title determination south of Karratha.The WA Government will provide $2.7m in initial support to NAC to undertake surveys, approvals works and technical activities over the next 12 months that will lead to the activation of the first park.The Burrup (Murujuga) corridor is one of four priority corridors under the WA Government's Pilbara energy transition plan to accelerate the decarbonisation of heavy industry in the region by connecting industry with renewable energy generation.Ngarluma Country includes the coastal towns Karratha, Roebourne, Wickham, Point Samson and out to Whim Creek and is home of much of the Pilbara's industry including Rio Tinto (ASX: RIO), Dampier Salt, Woodside, Yara and Perdaman.NAC is targeting 5GW of development in its green energy parks while also creating employment, training and long-term income for the Ngarluma people.WA Energy and Decarbonisation Minister Amber-Jade Sanderson says creating jobs through the Pilbara energy transition plan is a key part to making WA a renewable energy powerhouse."Supporting NAC and Perdaman in this landmark partnership is another step in decarbonising the Pilbara and realising the considerable benefits of the region's renewable energy resources,” she said.The solar farm will feed into the common-use Maitland-Karratha-Burrup transmission corridor and aid the activation of the Maitland strategic industrial area.NAC and Ngarluma green energy director Belinda Churnside says the Ngarluma people are proud to be leaders in the development of the energy transition.“Ngarluma green energy parks will be a game changer for the fast and straight forward development of large-scale renewable projects,” she said.The green energy park is expected to be activated through the connection of the solar farm to Perdaman's project Ceres urea plant by mid-end of 2027.Drive to make WA renewable energy powerhouse continues with Warradarge wind farm expansion, with four of 30 additional turbines being erected at the site.Once completed, the expanded Warradarge wind farm will provide up to 283MW of clean energy — enough to power approximately about households — making it WA's largest wind farm both by capacity and energy generated.The expansion is part of the WA Government’s goal to exit from state-owned coal-fired power by 2030."Wind turbines going up as part of the expansion is our renewable energy transformation taking shape, delivering jobs, economic diversification and clean energy,” Minister Sanderson said." will deliver more renewable energy for households and businesses, while work to expand the South West Interconnected System (SWIS) transmission grid will unlock more renewable energy from the mid-west."

Liebherr’s T 264 mining trucks are proving their reliability in one of WA’s most demanding environments, with a fleet now working at a Thiess-operated site in the Pilbara.With high temperatures, abrasive materials and demanding production schedules, mining in the Pilbara region presents a challenging environment.Thiess mining manager Kathryn Harrison says comments on the performance of the T 264s.“What we’re looking for in our machinery is that it can withstand those extremes of temperature, presence of dust, wet weather conditions, as well as hauling some serious dirt,” she says.That expectation is being met in day-to-day operations.Thiess maintenance manager Rob Sue says despite the conditions, the trucks have performed.“We can’t ask any more of the product than that,” he said.“The support from Perth has been phenomenal.”This partnership keeps trucks operating efficiently and reliably in one of the world’s toughest mining environments.
