Snapshot	The Cinovec Project is the largest hard rock lithium deposit in Europe and by far the largest hard rock lithium deposit in the European Union. Cinovec has been designated a Strategic Project by the European Union under the Critical Raw Materials Act and a Strategic Deposit by the Czech Government. Cinovec 2025 Definitive Feasibility Study confirms Long-life Battery Grade Lithium Carbonate Producer Strategically Positioned to supply European EV and Energy-storage Sectors. Cinovec has received impetus from the EU and the Czech Government in the form of grants of USD36 million from the EU Just Transition fund and up to EUR360 million by the Czech Government. The full Environmental Impact Assessment (EIA) for the Cinovec Lithium Project (Project) was formally submitted to the Czech Ministry of the Environment on 31 December 2025. EIA submission satisfies a key condition of the EU Just Transition Fund grant.

Deposit type

• Greisen hosted

Summary:

Cinovec is a granite-hosted tin-tungsten-lithium deposit.

Late Variscan age, post-orogenic granite intrusion. Tin and tungsten occur in oxide minerals (cassiterite and wolframite). Lithium occurs in zinnwaldite, a Li-rich mica.

Mineralization is in a small granite cupola. Vein and greisen type. Alteration is greisenisation, silicification, albitisation.

Geological Setting
The Cínovec deposit lies in the Krušné hory-Erzgebirge region at the northern border of the Bohemian Massif. In a regional sense, the Cínovec deposit is related to a composite partly hidden granite pluton approximately 6,000 km³ in size.

The deposit is hosted in the upper part of the Cínovec granite cupola. The Cinovec granite is a strongly fractionated, slightly peraluminous A-type granite. The upper part of the granite intrusion is characterised by increased content of zinnwaldite a lithium-bearing mica. The base of the zinnwaldite granite sits on less fractionated biotite granite.

Mineralisation and Deposit Type
Cínovec ore mineralisation can be divided into Sn-W quartz vein and Li-greisen associations. High-grade tin and tungsten veins that occur in the uppermost part of the Cínovec cupola were subject to historical mining. The grades of veins in places reached high percentages by weight of Sn and W, but their content was very heterogenous often consisting of barren quartz only.

The highest-grade lithium mineralisation is associated with the greisen - a secondary rock replacing granite, composed of zinnwaldite and quartz, with subordinate feldspar, fluorite and topaz.

Zinnwaldite (KLiFeAl (AlSi3) O10 (OH,F)2) is the dominant lithium-bearing phase. The lithium content in the greisen bodies is 0.3 wt.% to 1.0 wt.%, categorising the greisen bodies as a world-class lithium resource.

Dimensions
The Cinovec Deposit strikes north-south, is elongated, and dips gently south and east parallel to the upper granite contact, dip at western rim is steep. The surface intersection of mineralization is about 1km long and 900m wide.

Mineralization extends from about 200m to 500m below surface.
