Zinnwald Lithium’s core technology is the production of battery-grade lithium hydroxide (LiOH) via underground mining and on-site chemical processing. Its methods minimize environmental impact through reduced water usage and energy demand and aim for zero waste by producing by-products such as sulfate of potash, precipitated calcium carbonate, and quartz sand. Technical partnerships with AMG, Metso, Epiroc, and K-UTEC support advanced processing technologies.
Zinnwald’s primary product is battery-grade lithium hydroxide (LiOH) for lithium-ion batteries. It also produces by-products including sulfate of potash fertilizer, precipitated calcium carbonate for paper manufacturing, and quartz sand for construction.
Flagship Zinnwald Lithium Project in southeastern Germany integrates underground mining and on-site processing to produce battery-grade LiOH. The project targets first production in 2026 with a projected pre-tax NPV8 of $1.6 billion, IRR of 39%, and a 3.3-year payback. It includes resource expansion at Falkenhain, Altenberg, and Sadisdorf licenses and partnerships such as Metso for mineral beneficiation and collaboration with local authorities and the Saxony community. Recent activities include an 84-hole infill drilling campaign and detailed mine design.
In 2025, Zinnwald Lithium Plc raised £3.0M led by AMG Critical Materials N.V. (£2.0M), Henry Maxey (£0.5M), and Mark Tindall (£0.42M), with additional contributions from Ganfeng International Trading and Oberon Securities. AMG Critical Materials N.V. holds 33.5% of share capital, Henry Maxey 14.6%, Mark Tindall 6.5%, Ganfeng International Trading 5.4%, and Oberon Securities 3.0%.
