Shareholders of Zinnwald Lithium were set to decide on the proposed acquisition of the company by AMG Lithium, a wholly owned subsidiary of Amsterdam-listed AMG Critical Materials, with the transaction aimed at transferring full ownership of the Zinnwald lithium project in Saxony, Germany. A court meeting and general meeting were scheduled for 13 July 2026 to consider the recommended cash-and-share offer. At the time of the monitoring cut-off, no confirmed voting outcome had been published.
AMG offer values Zinnwald at £57.18 million
Under the proposed transaction, AMG is offering 5 pence in cash and 0.001577 AMG shares for each Zinnwald share. Based on the reference AMG share price and exchange rate used when the offer was announced, the proposal represented an implied value of approximately 10 pence per Zinnwald share.
The transaction values Zinnwald at around £57.18 million on a fully diluted basis. AMG already owns approximately 29.32% of Zinnwald, with the value attributable to shares not already held by AMG estimated at approximately £41.28 million when the offer was announced. The acquisition remains subject to shareholder approval, court approval and regulatory conditions. Completion is expected around 27 July 2026, provided the scheme of arrangement becomes effective.
Lithium project would join AMG’s European processing platform
The proposed acquisition would give AMG full ownership of the Zinnwald lithium project, located in Saxony near the German-Czech border. The project would become directly linked with AMG’s existing lithium processing operations at Bitterfeld-Wolfen, where the company operates a lithium hydroxide refinery with an initial nameplate capacity of approximately 20,000 tonnes per year.
The transaction would allow AMG to manage the development pathway of the upstream lithium resource alongside its downstream conversion capacity. This includes control over project scheduling, feasibility activities, permitting strategy, processing design and potential integration of German lithium feedstock into AMG’s refining operations.
Acquisition changes project financing structure
The proposed takeover would remove the financing constraints associated with advancing a large underground lithium development through a smaller AIM-listed company. Zinnwald has previously raised approximately €38 million in cash to support project development.
Construction of the lithium project will require a significantly larger capital package supported by feasibility-level engineering, regulatory approvals and potential public or strategic financing sources. The acquisition would shift responsibility for advancing the project toward AMG’s broader industrial platform and financial resources.
Future milestones remain focused on development approvals
If approved, the transaction would represent another European critical-minerals project moving from junior-market ownership into a larger vertically integrated industrial group. Following completion, key project milestones would continue to include the definitive feasibility study, final mine and processing design, environmental approvals and development of a construction-financing structure. The proposed acquisition remains dependent on the successful completion of shareholder, court and regulatory approval processes.
