Zinnwald Lithium plc - Permit granted for exploration tunnel

The Zinnwald Lithium Project is a significant, integrated lithium development located in Saxony, Germany, which is being progressed with the aim of producing battery-grade lithium hydroxide (‘LiOH’) to support Europe’s growing demand for critical raw materials. The project hosts one of the largest hard-rock lithium resources in Europe, underpinned by a published Mineral Resource Estimate of 193.5 million t (Measured and Indicated) and a Proven and Probable Reserve of 128.1 million t, supporting long-term production potential.

As outlined in the company’s Pre-Feasibility Study (‘PFS’), the development concept includes an exploration decline of approximately 1 km intended to provide direct underground access to the ore body, for which a construction permit has now been granted by SOBA. This tunnel starts from a portal located at the brownfield site of the former Zinnwald Border Station, adjacent to the federal highway B170 between the villages of Zinnwald and Altenberg. The Border Station site has been largely unused since the Czech Republic acceded to the Schengen area in 2007.

The exploration tunnel is expected to improve the company’s geotechnical, seismic, and hydrogeological knowledge of the ore body, provide practical insights into mining conditions, and help to plan the ultimate mining operations. It will also facilitate the extraction of a significant representative bulk sample of up to 2000 t for further large scale metallurgical testwork and sample generation post a final investment decision to support detailed design activities and product qualifications.

The information obtained from the exploration tunnel is expected to support future permitting and design activities, and as outlined in the PFS, the decline may be incorporated into the permanent mine infrastructure, subject to development approval.

The exploration tunnel permit, valid until 31 December 2027 with the potential to be extended, does not provide the right to mine the deposit. Mine production from the deposit will be subject to receiving the appropriate permits, including completion of an environmental impact assessment and a public consultation process.

Anton du Plessis commented: “Obtaining the permit to construct the exploration tunnel, following a comprehensive submission process, is an important step in the ongoing de-risking of the Zinnwald Lithium Project, enabling the collection of important data to support future design and development planning. This permit enables the first new access development to the Zinnwald ore body and underlines that the Project meets the technical and regulatory requirements to successfully obtain the necessary permits from the Saxon Mining Authority.
