Element 25 Butcherbird Manganese Expansion Gains Funding for Battery Supply Chain

Element 25

Element 25 Butcherbird manganese expansion has moved forward after the Australian metals producer raised $18mn in equity to support the next phase of mine growth. The funding will help expand manganese concentrate output from the Butcherbird mine in Western Australia.

The project is expected to triple Butcherbird’s manganese concentrate production to 1.1mn t/yr from 365,000 t/yr. Full mechanical completion and commissioning are expected in the first quarter of 2027.

Element 25 Butcherbird manganese expansion is strategically important because the mine will supply feedstock for the company’s planned battery-grade manganese sulphate refinery in Louisiana. That project links Australian ore supply with US battery materials processing.

The expansion also strengthens Element 25’s role in the electric vehicle supply chain. The company already has offtake agreements with General Motors and Stellantis, giving the project direct exposure to automaker demand for non-China battery materials.

Butcherbird Expansion Builds Manganese Feedstock Scale

Western Australia’s state government approved the Butcherbird expansion in March 2025. The mine is expected to operate for at least 18 years, giving Element 25 a long-term feedstock platform.

The planned increase to 1.1mn t/yr of manganese concentrate would materially change the scale of the operation. Higher concentrate output should support downstream conversion into battery-grade manganese sulphate while also leaving room for sales into traditional steel markets.

Manganese remains a key steelmaking input because it improves strength and toughness. Element 25 plans to sell excess concentrate to steelmakers, creating a secondary demand channel outside batteries.

However, the main strategic value is in batteries. Manganese is increasingly important for lithium-ion battery chemistries as automakers seek lower-cost, more secure and less cobalt-dependent cathode materials.

Louisiana Refinery Links Australia to US Battery Materials Policy

Element 25’s manganese concentrate will mainly feed its battery-grade high-purity manganese sulphate monohydrate facility in Louisiana. The refinery is planned for 135,000 t/yr of production capacity.

The US government backed the Louisiana refinery with a $166mn grant in January last year. This support reflects Washington’s effort to build domestic processing capacity for battery materials and reduce reliance on China-controlled supply chains.

The Australian government also opened a A$50mn loan package in June to support the Butcherbird expansion. Together, the US and Australian support show how allied governments are trying to connect mining, refining and EV manufacturing supply chains.

Element 25 Butcherbird manganese expansion therefore fits a broader industrial strategy. Australia provides the resource base, while the US builds refining capacity closer to automakers and battery manufacturers.

The project’s success will depend on execution at both ends of the chain. Butcherbird must deliver concentrate at scale, while Louisiana must convert that material into battery-grade sulphate that meets customer specifications.

The Metalnomist Commentary

Element 25’s project shows how manganese is moving from a steelmaking material into a strategic battery supply input. The key challenge will be proving that mine expansion and US chemical refining can scale together on the timeline automakers require.
