Volunteers keep WA trail in top shape  A team from Alcoa Australia’s (ASX: AAI) Willowdale bauxite mine recently lent a hand to refresh a section of the iconic Munda Biddi Trail in WA. Stretching more than 1060km from Mundaring to Albany, the Munda Biddi is a world-class long-distance off-road cycling trail.  Senior community relations advisor Scott Hansen says Alcoa Australia has proudly supported the Munda Biddi Trail Foundation (MBTF) for 25 years through funding and employee volunteering. “Alcoa has a long-running partnership with the foundation, a not-for-profit association which supports the maintenance and promotion of the trail,” he said. Recently, employees rolled up their sleeves to clean up a section of the trail near the northern part of Alcoa Australia’s Willowdale Larego mine area. Their efforts included branch trimming, raking and blower vaccing to ensure the trail remains safe and accessible for riders. “Our employees are proud to help maintain this popular trail,” Mr Hansen said.“It’s a great way to give back to the community and keep the trail safe and functional for cyclists.” Alcoa Australia’s involvement with the trail dates back to its planning in 2000, when the company worked with the foundation to determine a safe, practical and enjoyable route and provide on-the-ground help to make the trail a reality.Since then, Alcoa Australia has continued to consider the trail through mine planning processes, including the recent expansion of a Mining Avoidance Zone (MAZ) around Dwellingup. The expanded MAZ is adjacent to several designated conservation areas and includes recreational tracks and trails, including sections of the Munda Biddi Trail, Bibbulmun Track and Nyingarn Bidi Loop. If future mine planning indicates any interactions with the trail, Mr Hansen says Alcoa consults with the MBTF and the Department of Biodiversity, Conservation and Attractions to discuss options that ensure access is not restricted.Past consultation has resulted in Alcoa Australia building dedicated infrastructure such as tunnels and bridges to provide safe, continuous access for riders through operating mine regions. “Our overarching principle is to maintain continuous access for trail users and we want to ensure this world-class trail remains available for generations to come,” Mr Hansen said.MBTF executive officer Therese Logue says the trail’s ongoing success is founded on strong collaboration across both community and corporate sectors, including a longstanding 25-year partnership with Alcoa Australia. “The continued support of Alcoa extends beyond industry operations, with staff actively contributing their time and skills,” she said. “Their hands-on involvement builds a sense of stewardship, directly helping to preserve this iconic trail. “Through partnerships like these, the trail will continue to flourish, and the provision of vital resources help the foundation empower its volunteers to enhance and maintain a high-quality trail experience for all riders.”  

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."

EACON hits autonomous haulage milestone in Australia A retrofitted Komatsu HD1500 haul truck has successfully completed its first fully autonomous haulage test cycle at Norton Gold Fields' Mulgarrie mine in WA.The achievement is part of a tri-partite project between EACON Mining Technology, Thiess and Norton Gold Fields, confirming the successful retrofit of autonomy on Komatsu trucks.Prior to the retrofit, the truck had about 20,000 operating hours and was elected as part of the project to broaden asset life.Following a structured series of testing and validation activities, the retrofitted truck, named Jerry, has met the criteria to operate fully autonomously, demonstrating the maturity of EACON's complete autonomous driving system under Australian operating conditions.The first phase of the project demonstrated reliable integration of EACON's independently developed drive-by-wire retrofit kit, consistent vehicle behaviour under autonomous control and effective tuning of control algorithms to match the truck's native operating characteristics.Comprehensive system-level validation was completed across perception, planning, decision-making and vehicle control, confirming the system's readiness for continued on-site testing and subsequent project phases.EACON Mining Australia chief operating officer Elaine Jin says the milestone reflects disciplined execution and close collaboration across all project partners."Achieving this milestone safely and on schedule validates the maturity of our ORCASTRA system, its adaptability to the Australian mining environment and its proven performance on large scale rigid dump trucks,” she said.Thiess assets and autonomy group executive Ryan Kirkwood says the global mining services provider was proud to work in partnership with EACON and Norton Gold Fields to demonstrate how autonomy could be introduced safely across mixed, brownfield fleets."Thiess has implemented, operated and optimised autonomous solutions for haulage fleets, dozer and drill applications globally for close to 15 years,” he said.“We're pleased to bring our experience to this project to support change management and implementation processes, from commissioning through to successful maintenance with our workforce of the future."Supporting fleet expansion and further validation activities, a second Komatsu HD1500 truck, Tom, has also recently completed retrofit works and is making its way to the Mulgarrie site.Norton Gold Fields chief executive Wei Lin says the milestone demonstrates the potential for retrofit autonomous haulage to be safely introduced into active Australian gold mining operations.“The project has progressed in a structured and measured way, with safety and operational readiness at the forefront,” he said.By enabling autonomy across multiple vehicle brands and models, EACON's open, OEM-agnostic autonomy solution provides a practical pathway for upgrading existing mining fleets and facilitates the transition of autonomous haulage from greenfield deployments to scalable brownfield and retrofit operations.
