Zinnwald Awarded German R&D Grant and Official Seal

Zinnwald Lithium plc, the European focused lithium company developing the integrated Zinnwald Lithium Project in Germany (the "Project"), is pleased to announce that it has been awarded a grant of up to €1.9 million under the German Forschungszulage scheme. As part of this recognition, Zinnwald has also received its official seal from the Bescheinigungsstelle Forschungszulage ("BSFZ") as proof of its 'entrepreneurial innovation competence'.

This scheme was introduced in Germany in 2020 to promote and accelerate corporate research and development ("R&D"). It is a government-funded tax incentive scheme that reimburses eligible R&D expenses. Eligible projects must be in fundamental research, industrial research, or experimental development. Zinnwald submitted two applications, one for its geological R&D studies into the extraction of lithium from micas, and the other for its innovative processing development work, both of which were reflected in its Pre-Feasibility Study in 2025. Both applications were approved by the BSFZ resulting in an overall grant of up to €1.9 million to be received later in 2026.

Anton du Plessis CEO of Zinnwald Lithium plc, commented, "We are delighted to receive both the grant and the official seal of approval from the BSFZ. It is a strong endorsement of the R&D work that culminated in our PFS that showed the Project to have the largest reserves of any hard rock lithium project in Europe and an innovative processing flowsheet for the production of battery-grade lithium hydroxide."

BSFZ Seal

The BSFZ seal is a proof of entrepreneurial innovation competence. The BSFZ only awards the seal to companies that are allowed to claim funding through the research allowance. The BSFZ awards the seal in two variants, with the one received by Zinnwald reflecting its own research and development activities.
