Zinnwald Lithium and Metso Advance Joint Testwork Program

Zinnwald Lithium plc ('Zinnwald Lithium'), the European focused lithium company developing the integrated Zinnwald Lithium Project (the 'Project') in Germany is pleased to announce that, in conjunction with Metso, it continues to make excellent progress developing the beneficiation plant concept for the integrated Zinnwald Lithium Project located near to Dresden, Germany. This unique project, which is situated in the heart of the European chemical and automotive industries, is designed to supply battery grade lithium hydroxide (LiOH) to the electric vehicle battery sector.

Metso was engaged to assist Zinnwald Lithium with its Definitive Feasibility Study in early 2022.  Since then, the two companies have been working on developing a successful beneficiation process flowsheet based on a complete mineralogical study, batch, and locked cycle tests. The design basis of the tests considers the mixture of two distinctive lithium ore types, Albite Granite and Quartz Mica Greisen, potentially expanding the resource base considerably.

Zinnwald Lithium CEO, Anton du Plessis, commented: "Achieving resilience and sustainability for the electric vehicle battery supply chain is essential, including in Europe where over 30 new gigafactories are planned by 2030. Our vision is to build a world-leading integrated lithium hydroxide operation to support this supply chain, adhering to the highest environmental standards. We are therefore delighted with the progress being made with Metso as we look to design the best possible particle sorting, otherwise known as beneficiation process, for the plant.

"After the completion of the beneficiation pilot, we will start refinement of the calcination and hydrometallurgical flowsheet. We have partnered with Metso to develop and deliver this project as a 'one-stop shop' to reduce the need for engagement with multiple suppliers and to maximize in-house know-how in the design of the plant from Run-of-Mine to the battery-grade final product."

Mikko Rantaharju, Vice President, Hydrometallurgy at Metso added: "Metso is delighted to support Zinnwald Lithium with the development of this ambitious project. Development and supply of state-of-the-art, sustainable processes and equipment for the critical minerals required for the electric vehicle supply chain is an essential part of our minerals processing expertise."
