What Zinnwald Lithium does

Zinnwald Lithium Plc is a UK-incorporated, AIM-listed (ZNWD.L) mineral development company that, through its wholly-owned German subsidiary Zinnwald Lithium GmbH, is developing the Zinnwald Lithium Project in the Ore Mountains (Erzgebirge) of Saxony, Germany. The asset hosts the second-largest hard-rock lithium resource in the European Union at approximately 2,662,000 tonnes of lithium carbonate equivalent, supporting an estimated 41-year mine life. The project's planned product is battery-grade lithium hydroxide (LiOH), targeting European battery manufacturers and automotive OEMs located within roughly 150 km of three planned gigafactories.

The technical concept combines underground conventional mining (drilling and blasting) with mineral beneficiation and a hydrometallurgical refining circuit using Metso's water-based alkaline leach process, which delivers above 95% lithium recovery with non-toxic by-products. Brownfield reuse of the historic Altenberg tin mine infrastructure (access tunnels, ventilation, rail) reduces surface disruption and capital intensity. Phase 1 targets 18,000 tonnes per annum of LiOH, with Phase 2 planned at 35,100 tpa at peak operation. Integrated processing is expected to produce commercial by-products including SOP fertiliser (~57,000 tpa), precipitated calcium carbonate (~16,900 tpa), calcium silicate, calcium fluoride, potassium chloride, and quartz sand.

The business model is pre-revenue and asset-development stage, with no current commercial sales, no disclosed pricing, and a projected first production date of 2030 subject to permits and financing. The go-to-market is direct B2B sales to European lithium-ion battery manufacturers and automotive OEMs, supported by a project pipeline that benefits from the EU Critical Raw Materials Act framework. Revenue mechanics will combine LiOH sales with by-product chemical sales into construction, agriculture (SOP), paper (PCC), and chemical industry channels. The project is positioned as a strategic EU CRMA asset, and as of May 2026 AMG Critical Materials N.V. (already a 29.3% shareholder) announced a recommended acquisition of the remaining ~71% stake for approximately $56 million, expected to close in Q3 2026.

Core offering

Zinnwald Lithium is developing an underground hard-rock lithium mine and integrated processing operation in Saxony, Germany, to produce battery-grade lithium hydroxide (LiOH) for the European EV and energy storage markets. Phase 1 targets 18,000 tonnes per year of LiOH, scaling to 35,100 tonnes per year in Phase 2, supported by a resource base of 2.66 million tonnes of lithium carbonate equivalent and a projected mine life exceeding 40 years. The processing operation also yields commercial by-products including SOP fertiliser, precipitated calcium carbonate (PCC), quartz sand, calcium silicate, and calcium fluoride.

Product overview

Zinnwald Lithium is a multi-product mining and processing project in the Ore Mountains (Erzgebirge) region of Saxony, Germany. The company operates as a 100% European business with a portfolio of five distinct products and by-products. The core product is battery-grade lithium hydroxide (LiOH), targeting Europe's electric vehicle and energy storage battery market. The integrated processing operations produce three additional industrial by-products: quartz sand (a coarse aggregate from ore processing), a suite of industrial chemicals (calcium silicate, PCC, calcium fluoride, potassium chloride), and SOP fertiliser. The project plans phased development — Phase 1 producing 18,000 tpa of LiOH, Phase 2 expanding to approximately 35,100 tpa peak production — over a mine life exceeding 40 years.

Products and services

• Lithium Hydroxide (LiOH) Battery-grade lithium hydroxide (LiOH), the primary product of the Zinnwald Lithium project, intended for European battery manufacturers producing lithium-ion cells for electric vehicles and energy storage systems. The average electric vehicle currently requires around 15 kilograms of LiOH.
• Industrial Chemicals A range of industrial chemical by-products produced alongside lithium from the integrated processing operations, including calcium silicate (construction and thermal/fire protection), calcium fluoride (hydrofluoric acid and metallurgy), and potassium chloride (fertiliser applications).
• Quartz Sand Coarse-grade quartz sand produced as a by-product of ore processing, usable as an inert aggregate for road construction and other building projects.
• SOP Fertiliser (Sulfate of Potash) Sulfate of potash (SOP) fertiliser produced as a by-product of lithium processing, used for high-value crops including fruits, vegetables, and nuts.
• Precipitated Calcium Carbonate (PCC) Precipitated calcium carbonate (PCC) produced as a by-product of lithium processing, used as a filler in high-quality paper making to improve opacity, brightness, strength, and printability.
