Newmont’s Lihir: One of Papua New Guinea’s largest gold mines Papua New Guinea (PNG) is rich with gold, copper, nickel and cobalt deposits, with mining playing a key role in shaping the country and its economy. The mineral resources in the country got little attention until the late nineteenth century when prospectors form North Queensland began travelling in search for alluvial gold. From 1896, there were attempts to exploit the gold loads and although some small mines yielded good results, all were abandoned by 1923. Unlike many other mining districts in PNG, Niolam island – a geothermally extinct volcano doesn’t have a history of alluvial gold mining. Gold traces were...

Mount Isa: moving on up After 60 years of copper mining in North West Queensland, the Mount Isa Mines underground copper operations, comprising Enterprise, X41, Black Rock and its copper concentrator will close in the second half of 2025. In its heyday, it was the second largest copper producer in Australia and a key asset in Glencore’s global mining portfolio. Now, about 1,200 people are grappling with looming job loss in the small mining town of Mount Isa with a population of about 22,000. Glencore chief operating officer of Australian zinc assets Sam Strohmayr says Mount Isa Mines will continue operating its zinc mining and processing assets in the region....

Golden Grove: 35 years young In the heart of WA’s midwest region lies Golden Grove mine, a cornerstone operation of the Australian mining landscape. Since its first discovery in 1971, Golden Grove has undergone numerous transformations, adapting to market shifts, technological advancements, and evolving industry demands. What began as a humble exploration site has grown into a prolific source of precious metals. The mine site celebrates 35 years in 2025 following the start of operations in 1990, focusing on the extraction of copper, zinc, lead and precious metals such as silver and gold. Today, mining at Golden Grove is from two...

Q&A with BCI Minerals managing director David Boshoff On 10 September, BCI Minerals (ASX: BCI) received Federal Government approval to commence operations at the Mardie salt and potash project in the Pilbara region of WA and to continue construction in the northern envelope of the project. This critical milestone comes as Asian demand for salt is expected to outstrip supply over the coming decades, in part due to new chloralkali and caustic soda plants in China and Indonesia, reduced production in Mexico and India predicted to becoming a net importer. Except for Mardie, no other sizeable salt projects are being commissioned. The project...

MINExpo - What Happened in Vegas… In the case of MINExpo International 2024, what happened in Vegas should definitely not stay in Vegas. This enormous expo brought together an eclectic mix of equipment, technology, innovation and sheer brute strength at an unprecedented scale. To put that scale into perspective, the exhibition covered over 850,000 square feet. That may not mean a great deal to us in Australia but that equates to 7.8-hectares or over 19.5-acres. Spread across this vast floor area were over 2000 exhibitors representing every facet of the mining industry, from...

AirSteril Technology Mitigates Air Quality Challenges for Mining Industry The mining industry, particularly in underground settings, faces severe air quality challenges, which have long posed risks to workers’ health and safety. Underground mining operations continuously generate high levels of airborne contaminants, including dust, gases, and particulate matter, due to activities like drilling, blasting, and material handling. The confined nature of these environments exacerbates the problem, allowing dust and harmful gases to potentially accumulate in hazardous concentrations. Among the most dangerous contaminants are ultra-fine dust particles, such as coal dust and silica, which can easily become respirable and penetrate deep into miners' lungs. Exposure to these fine and ultra-fine particles can lead to chronic and debilitating lung diseases, such as coal...
