Wagerup validates WA as a non-Chinese gallium hubAustralian, US and Japanese backing opens funding and offtake pathways for juniorsNimy needs its own process but can benefit from Alcoa’s expertise and strategic momentum
Gallium may melt in the hand, but its strategic weight has placed Western Australia at the centre of the push to loosen China’s grip over a highly concentrated critical mineral supply chain.
This month Alcoa Corporation (ASX:AAI) reached a final investment decision on the development of a gallium plant at its Wagerup alumina refinery in WA’s South West.
Backed by government funding and support from Australia, the US and Japan, it will make Australia one of the largest producers outside the Middle Kingdom of a metal essential to the burgeoning AI race.
And other Australian gallium resource holders are watching. Alcoa’s competitive advantage is the massive bauxite resources the Pittsburgh-based miner process through its WA operations. Gallium is a by-product of the Bayer process, used to refine bauxite into alumina, and Alcoa’s resource base is set to get much bigger with its proposed acquisition of neighbour South32’s (ASX:S32) aluminium business.
But juniors looking to extract gallium through other means like the signal the Alcoa FID shows. In a market once too niche to fund, there is now a pathway to development in the West, and especially in resource rich Western Australia.
Nimy Resources (ASX:NIM) managing director Luke Hampson said the development strengthened the position of WA explorers seeking alternative supply.
“Alcoa’s commitment to the gallium production plant reflects the strong outlook for this critical metal and the need for the western world to develop alternative supplies to China,” he said.
Hub catalyst
Gallium is produced in small volumes, but its role across semiconductors, defence, telecommunications and advanced electronics gives supply control disproportionate strategic weight.
China accounted for 98% of global primary refined gallium production in 2023, according to the US Geological Survey. Yet gallium is rarely mined in its own right, instead being recovered as a by-product of much larger bauxite and zinc operations.
This dynamic produces a textbook supply-chain choke point. Because gallium output is locked to alumina and zinc production, supply cannot quickly adjust to price signals. Chinese export controls imposed in 2023 have increased Western efforts to secure alternative sources and driven European prices to roughly five times Chinese levels.
In this context, Wagerup functions as more than just a processing facility.
The proposed plant could deliver around 100 tonnes of gallium a year, or about 10% of global demand. While its direct economic impact may be limited, its value to allied supply chains would be tactically important.
Wagerup would add commercial-scale processing, specialist expertise and international customer networks to a region that already hosts gallium discoveries and research capacity. Centralising resources, technology and market access in this way is how critical minerals hubs emerge.
Market pathway
The Center for Strategic and International Studies has warned China could flood the small, opaque gallium market to crush prices.
Alcoa’s investment does not remove those hurdles, but it demonstrates that WA gallium projects can attract serious capital and political backing when they are technically credible and strategically matched.
Australia has committed up to US$200 million in concessional equity through Export Finance Australia, while the US and Japan have supported the development through strategic partnerships and potential purchasing arrangements.
Japan’s involvement includes a partnership between its government and Sojitz, while funding has been contemplated in exchange for rights over future output.
Developers can now point to Wagerup when approaching export-credit agencies, critical minerals funds, defence buyers and semiconductor companies. They can show that Australian gallium is a commodity allied governments are willing to finance and buy.
Nimy, which unlike Alcoa is looking to be a rare primary gallium producer, is already pursuing that opportunity through its relationship with US critical mineral group M2i Global.
Material from its Block 3 deposit at the Mons project in WA has been sent to the US, where academic and defence-linked organisations are assessing refining routes and product specifications.
Its non-binding agreement with M2i includes prospective gallium sales, introductions to financiers and engagement with US government buyers.
Nimy’s test
Nimy is among the most advanced WA juniors seeking to convert that strategic interest into an ore-based development.
Mons is around 370km northeast of Perth and hosts a maiden inferred resource at Block 3 of 7.23Mt grading 102g/t gallium trioxide using a 70g/t cut-off.
At a lower 20g/t cut-off, the resource expands to 64.3Mt at 42g/t. The higher-grade resource starts near surface and remains open, while magnetics indicate the host unit may extend another 3.5km.
Nimy is working with Curtin University on a two-year extraction and refining program backed by $550,000 from the Minerals Research Institute of Western Australia, alongside Strategic Metallurgy testwork and a scoping study covering mining, processing, costs and markets.
These programs position Nimy to tap into the ecosystem forming around Wagerup, without depending on Alcoa to process its ore.
The company can draw on expanding research capacity, increased government familiarity with gallium and direct engagement with allied customers. Hampson said Nimy also expects European and Asian interest alongside its US relationships.
Processing hurdle #
Metallurgy is the real test.
At Wagerup, gallium is already dissolved in the Bayer-process liquor generated by alumina refining, allowing Alcoa to bolt a recovery circuit onto an operating plant with secure feedstock, utilities, laboratories and logistics.
Nimy’s challenge is more complex. The company needs to engineer an ore-based flowsheet that can mine and concentrate its chlorite-rich material, recover gallium at a commercially viable cost, and deliver a reliable product that satisfies the demands of long-term buyers.
And recovery is just the start. Semiconductor supply chains demand gallium refined to 5N to 8N purity, depending on the end use, before it can be turned into compound materials and wafers. WA’s ambitions cannot end at primary production.
Without downstream refining and semiconductor-material capacity, the state risks moving the supply-chain bottleneck rather than solving it.
Wider pipeline
WA’s junior explorers are targeting gallium through three distinct strategies: building scale, pursuing co-product value, and leveraging bauxite-hosted mineralisation.
Projects span from large inferred resources to early-stage finds, but all confront the same hurdles: recovery, cost and market access.
Terrain Minerals (ASX:TMX) provides an earlier-stage addition through its Larins Lane discovery at the wholly owned Smokebush project, about 350km north of Perth.
Terrain has identified gallium-bearing oxide and clay mineralisation overlying rare earth elements and established a JORC exploration target across about 5% covering a larger 27km2 area.
Drilling has returned intersections up to 64m wide, with metallurgical results expected in late 2026. Terrain has also reported discussions with industry groups and prospective offtake partners.
The project is less advanced than Nimy.
Mount Ridley brings scale #
Mount Ridley Mines (ASX:MRD) has the largest resource, with 838.7Mt at 29.3ppm gallium for 24,584t of contained metal across three shallow blocks at its Grass Patch project near Esperance. The site also contains resources for similarly choked critical minerals rare earths and scandium.
The growth potential is significant but remains unquantified. MRD’s 2026 Phase 2 program centres on scandium re-assaying, which may underpin a resource update.
The main upside sits in open extensions and a 13km corridor southwest of Block 1 that remains untested for gallium, scandium and heavy rare earths.
Phase 1 metallurgical testwork has begun, testing mineral characterisation, beneficiation and leaching on clay from the Winstons and Keiths prospects. The next tests are repeatable recoveries, effective separation from other metals and producing a saleable product without prohibitive reagent use or cost.
“This new phase of test work sets the foundation for everything that follows from a processing standpoint,” CEO Allister Caird said in a statement to the ASX.
The testwork is being run by Perth lab Nogrom and overseen by Mt Ridley CTO Chris Larder, an veteran in assessing gallium and rare earths processing flowsheets in WA.
West Cobar adds tonnes #
West Cobar Metals (ASX:WC1) has outlined an inferred resource of 263 million tonnes grading 26 parts per million gallium at its Newmont and O’Connor deposits in the Salazar project, northeast of Esperance.
Gallium forms part of a larger suite of rare earths, scandium, titanium and alumina at Salazar, making it a likely co-product rather than the main economic engine. Re-assaying historical drill core and testing extensions beyond current mineralised boundaries could lift the project’s scale.
Earlier testwork delivered concentrates of rare earths, scandium and gallium, but West Cobar still faces the task of proving consistent recoveries and commercially viable multi-product flowsheets to secure funding, partners and offtake.
Western Yilgarn builds pipeline #
[ Western Yilgarn (ASX:WYX)](https://stockhead.com.au/company/western-yilgarn-wyx/) is earlier in the race but has built a pipeline across New Norcia, Cardea and Ida Holmes Junction.
New Norcia holds a 39.27Mt inferred bauxite resource, with the company targeting gallium-rich zones and aiming for a JORC-compliant gallium resource. Recent work at Cardea 1 has identified shallow mineralisation.
The present task is to convert assays into mineable tonnes through drilling, mineralogical analysis and metallurgical testwork. The central question is whether gallium can be recovered economically as a bauxite by-product or via a separate flowsheet.
Western Yilgarn’s bauxite-hosted position gives it the closest thematic link to Wagerup.
The rise of gallium as a critical mineral has seen WYX re-assay samples from projects where it hosts bauxite resources, with recent samples from its Cardea 1 deposit returning high-grade accumulations of the metal.
“As global demand for gallium continues to increase due to its critical role in semiconductors, defence technologies and advanced electronics, we believe Cardea 1 is rapidly emerging as a potentially significant Australian gallium project with strong strategic relevance,” Western Yilgarn non-exec director Pedro Kastellorizos said.
“These results provide a solid foundation for advancing the project toward systematic resource evaluation and further metallurgical assessment.”
