Greatland all-in on Australian gold As Australian gold giant Newmont (ASX: NEM) turns to give full attention to its tier one assets, London-based hopeful Greatland Gold is cutting a clear path to renewing a major mining complex in WA. With its planned acquisition of 100% of the Telfer mine and the remaining 70% of its neighbour, Havieron, for about $723m (US$475m), Greatland Gold is heading straight to the ASX. The company says it intends to establish dual listing within six months of acquisition completion. Why is the company going all in on its Australian assets? Greatland Gold chief executive Shaun Day says it’s about getting the best of both worlds. “We were...

Sustainable smelting at Tomago Aluminium 100% renewable energy by 2035 The aluminium industry is at a crossroads — although a key enabler of technology critical to the energy transition, the subsector itself is also energy hungry. The smelting process, where alumina is turned into aluminium metal, is a significant source of Scope 2 or indirect emissions, driven by electricity generation. As Australia’s largest aluminium smelter, Tomago Aluminium operates round-the-clock to produce 590,000tpa of aluminium, using around 10% of the NSW power supply each year....

PhotonAssayTM: minerals analysis technology delivers exciting results Since 1851, Australia has contributed $1t in gold, making it the third largest producer in the world, according to the Minerals Council of Australia. Although we’ve come a long way since the initial gold rush, accurate mineral analysis technology has been largely static, meaning the true value of gold and the essential metals that copresent with it, such as silver and copper, could still be unrealised. According to Australia’s national science agency, CSIRO, gold processing plants may only recover between 65-85% of the gold present in mined rock. This means hundreds of millions of dollars’ worth of gold and related metals are going to waste....

Shining a light on Sunrise Dam With gold prices reaching an all-time high of $3935oz (US$2685oz) in September 2024, gold mining companies are reaping the benefits as demand for this precious metal remains elevated. One such company is AngloGold Ashanti, owner of the Sunrise Dam operation which lies 205km north-northeast of Kalgoorlie and 55km south of Laverton in WA. Open pit production began in 1997 and was completed at the main pit in 2014 to a final depth of 500m below surface. After the Golden Delicious open pit was depleted last year, the main source of ore comes from the Vogue and Frankie zones, both of which are underground operations. Underground operations and production from Golden Delicious, while it was...

Mining in the Pilbara: A cut above the rest Not only is WA’s Pilbara region known for its stunning landscapes, but it’s also home to the world’s largest and most economically significant iron ore deposits. While copper, gold and iron ore deposits were identified in WA in the 1880s, the mining industry only started to develop in the Pilbara around the 1950s – 1960s. One of the first major discoveries in the Pilbara, the Goldsworthy iron ore deposit, was discovered in 1938 and extensively surveyed in the 1950s by the Mines Department (now known as the WA Department of Energy, Mines, Industry Regulation and Safety). In a call for tenders to develop Goldsworthy, the State Government invited further exploration for...

Forging global ties: BHP's WAIO business and China's steel market Australia is the world’s largest iron ore exporter and producer, exporting 892mt of the mineral in 2023, more than double the second largest of Brazil. China is the world’s largest iron ore importer, with the country importing nearly 1.12bt in 2023, or around 76% of the world’s supply for that year. Making up 5% of the Earth’s crust, iron ores are rocks and minerals from which metallic iron can be extracted. Iron ore is the primary source for the world’s iron and steel industries, with almost all (around 98%) of iron ore used in the steelmaking process....

Attracting innovation for rare earths Midstream processing in Australia In the third instalment of the Australian Mining Review’s critical minerals series, we speak with CSIRO senior principal research scientist Chris Vernon, ANSTO principal consultant Karin Soldenhoff and Australian Critical Minerals R&D Hub manager Lucy O’Connor for a deep dive into emerging mid-stream processing pathways for rare earths (RE) needed to achieve net zero emissions by 2050. Rare earths are a critical input for electric vehicle (EV) and wind turbine supply chains, playing a foundational role in the global energy transition. As demand for renewable technology increases domestically and globally, the RE market is also expanding, with the previously overlooked materials becoming increasingly attractive. By investing in domestic mid-stream processing capabilities...

BHP's 10 years of ABCs: Autonomous haulage, blasting and Caval Ridge BHP’s (ASX: BHP) Caval Ridge is one of five metallurgical coal mines in Queensland’s Bowen Basin, about 188km south-west of Mackay, and is a 50:50 joint venture between BHP and Mitsubishi Development (BHP Mitsubishi Alliance, or BMA). This year celebrates 10 years in operation. The greenfield project, which is the largest greenfield metallurgical coal-mining complex in Australia, covers an area of about 6,800ha and comprises two coal pits – Horse Pit and Heyford Pit. The former deposit lies north of Peak Downs Highway and the latter north of Harrow Creek. Caval Ridge is one of five mines...

The importance of Australia's manufacturing industry With intensifying competition from global markets, Australia’s manufacturing industry is facing extreme pressure to remain competitive. Given Australia’s abundant and critical natural resources, the country is well positioned to strengthen its standing and become an indispensable part of the global supply chain. Over the next decade, the Federal Government will invest $22.7b to build a ‘Future Made in Australia’ to secure Australia’s place in the changing global economic and strategic landscape as well as bring new jobs and opportunities to the workforce. As part of this, a Future Made in...

Harnessing the sun’s potential in mid-stream silicon processing In the second instalment of the Australian Mining Review’s critical minerals series, we speak with Australian Critical Minerals Research and Development Hub manager Lucy O’Connor, ANSTO high purity quartz project manager Neilesh Syna and ANSTO high purity quartz project technical lead Robert Fowles for a dive deep into emerging mid-stream processing pathways for silicon in order to achieve net zero emissions by 2050. Deployment of solar power is essential to the success of Australia’s energy transition. The nation stands to be a leader in this space, as we are equipped with the vast solar resources needed to meet global demands. However, the country is entirely reliant on overseas supply chains to produce...

The inside line on McPhillamys mine Prospects were golden for Regis Resources (ASX: RRL) at the start of August. With the McPhillamys definitive feasibility study (DFS) completed and final investment decision (FID) expected to be made in early CY26, Regis Resources had seemingly checked all the boxes for the $1b mine. The NSW gold project was expected to be a valuable asset, featuring a 7mtpa plant with 189moz contained gold and 60.6mt milled, with an expected mine life of over 10 years. This vision was quickly extinguished on August 16, when the Federal Environment and Water Minister Tanya Plibersek made a...
