Titanium deposits in South Australia
Titanium is a critical mineral for essential modern technologies, with applications in electric vehicles, battery storage, wind technology, pigments, and alloys for steel and superalloys. Australia is rich in mineral sand resources, and titanium deposits can be found across the country.
In South Australia, titanium deposits have been discovered in the Eucla Basin around the Great Australian Bight, as well as in the Murray Basin, which extends from Victoria into New South Wales. These deposits are typically found in mineral sand deposits associated with modern and ancient beaches and dunes.
A recent "world-class" titanium discovery in South Australia was made by emerging explorer Petratherm at its Muckanippie project near Coober Pedy. This discovery was made through reconnaissance mapping, surface sampling, and assaying of historic drill cores stored at the South Australian Government's core library. The drill samples confirmed the presence of titanium ore minerals ilmenite, leucoxene, and rutile, with grades ranging between 10 and 50 per cent titanium dioxide less than 10m from the surface.
The Australian Government has recognised the significance of this discovery, with SA Minister for Energy and Mining, Tom Koutsantonis, stating that the Muckanippie discovery could be "very significant for the nation." This discovery highlights the potential for further titanium exploration and mining developments in South Australia, contributing to the global market for titanium, which is expected to grow to nearly $US52 billion by 2030.

Titanium's critical role in green energy
Titanium is a critical mineral for essential modern technologies, and Australia is at the forefront of its discovery. In Western Australia, Empire Metals has made a significant titanium discovery, with mineralization up to 20% TiO2 over a +30km strike length. This discovery has the potential to be a globally unique, large-scale titanium project. Meanwhile, in South Australia, Petratherm has made a "world-class" titanium discovery at its Muckanippie project near Coober Pedy.
Titanium plays a critical role in the transition to green energy. Its unique properties make it a foundational element in various clean energy technologies. Titanium's strength-to-weight ratio provides remarkable durability without the added bulk of heavier metals, making it ideal for the robust infrastructure required in sustainable energy technologies. Titanium is also highly resistant to corrosion and harsh environmental conditions, reducing maintenance and replacement costs for solar panels and wind turbines.
In solar power, titanium dioxide (TiO2) improves the efficiency of photovoltaic cells by effectively converting sunlight into electricity. It is used as a semiconductor material and in dye-sensitized solar cells to enhance light absorption and energy conversion. Additionally, the photocatalytic properties of TiO2 make it useful in solar fuel generation, such as in the creation of hematene, which can extract electrical charge from photocatalytic activity.
In wind technology, titanium bolsters the structural integrity of massive wind turbines, enabling them to withstand extreme environmental conditions. Titanium alloys are also used in nuclear power plant components, particularly in cooling and containment systems, due to their ability to withstand extreme heat, radiation, and corrosive fluids.
Furthermore, titanium is essential in fuel cell components for electric vehicles and other hydrogen-powered applications. Its conductivity and corrosion-resistant properties ensure long-lasting, efficient operation. Titanium is also used in electrolyzers for green hydrogen production, as it can withstand acidic or alkaline environments during the process of splitting water into hydrogen and oxygen.
Overall, titanium's unique combination of strength, lightweight, and corrosion resistance makes it a critical enabler of renewable energy and energy efficiency. Its role in solar, wind, nuclear, and fuel cell technologies underscores its importance in the transition to a cleaner, greener energy future.

Titanium mineral sand deposits
Mineral sand deposits are found in every Australian state and the Northern Territory. Mineral sands contain economically important minerals with a high specific gravity, known as heavy minerals. The principal components of heavy mineral sands are rutile (TiO2), ilmenite (FeTiO3) and zircon (ZrSiO4). Rutile, leucoxene, and ilmenite contain titanium. Mineral sand deposits may also contain rare earth elements such as lanthanum (La), cerium (Ce), neodymium (Nd), and terbium (Tb), as part of the chemical structure of monazite and xenotime. However, rare earth elements are seldom present in commercially viable quantities in mineral sand deposits.
In Western Australia, mineral sand deposits are distributed from the southern tip of the state to Derby and are located at the present coastline or as relic deposits up to 35 km inland. Western Australia's mineral sands sector is dominated by two producers, Iluka Resources and Tronox Management, who produce the majority of the state's titanium minerals. Western Australia supplies mineral sands to 35 countries across every inhabited continent.
In Queensland, mineral sand deposits are found in Cape York. Large relic or old beach deposits are found as far inland as Ouyen in Victoria, and south-western New South Wales. In Victoria, mineral sand deposits occur far from the modern coastline, reflecting the presence of former inland seas and associated coastal processes that occurred tens of millions of years ago. Heavy mineral sand deposits occur in the Murray and Gippsland basins in northwest and southeast Victoria, respectively.
In South Australia, mineral sand deposits are found in the Eucla Basin around the Great Australian Bight. Petratherm made a 'world-class' titanium discovery at its Muckanippie project near Coober Pedy using reconnaissance mapping and surface sampling. Samples returned grades ranging between 10 and 50 per cent titanium dioxide less than 10m from the surface.
Exploration company Empire Metals also recently announced a major discovery at their 100% owned Pitfield Project in Western Australia, hitting significant titanium mineralization in initial drilling over a +30km strike length, with grades up to 20% TiO2 sampled at the surface near drill holes.
