Deposit

Cínovec–Zinnwald

Also known as Cínovec, Zinnwald, Zinnwald–Cínovec

A tin–tungsten–lithium greisen deposit straddling the Czech–German border in the Erzgebirge/Krušné hory, named Cínovec on the Czech side and Zinnwald on the Saxon side. Its greisen bodies carry zinnwaldite, a lithium-rich mica reaching about 5 millimetres in grain size, alongside quartz and topaz with minor cassiterite, wolframite and fluorspar.

What this record is, and who says so

Recognised on the basis of

Peer-reviewed study

A peer-reviewed publication whose subject is this deposit.

A deposit is an occurrence of sufficient size and grade that it might, under the most favourable circumstances, be considered to have economic potential. Lithoen records that a named authority made that judgement. It is not a statement that anything here is recoverable, and it is not a resource or a reserve.

Commodities documented here

Lithium (commodity)documented association
Carried in zinnwaldite, a lithium-rich mica, not in spodumene. No route from this deposit to any lithium product exists in this corpus.
Tin (commodity)documented association
Reported as a minor constituent, in cassiterite. The deposit is named by its sources as a Sn-W-Li greisen deposit.
Tungsten (commodity)documented association
Reported as a minor constituent, in wolframite.

Where it is

Lithoen holds no spatial representation of this deposit because neither source publishes one: both are mineral-processing studies that locate the deposit only by name and by the Czech–German border it straddles, and neither gives a coordinate, an outline or a sample location.

What Lithoen records

Each claim states how it is known and cites its evidence.

EstablishedPilot host installation: ALS Laboratories, Perth, Western Australia. Announced 9 November 2023. Feed: Cínovec ore described as representative of the first seven years of planned run-of-mine. Products reported: crude lithium carbonate 99.7 per cent; battery-grade lithium carbonate above 99.9 per cent after single-stage bicarbonation. Lithium hydroxide monohydrate work stated as underway. No European installation performed this work.

Reported for this deposit

The pilot programme that the project reports as producing battery-grade lithium carbonate from Cínovec ore was carried out at ALS Laboratories in Perth, Western Australia. The ore is described as fully representative of the run-of-mine planned for the first seven years of mining at Cínovec; the installation that processed it is in Australia. The material is Czech and the operation is not, and the two must not be collapsed. In 2020 the majority owner had separately stated that rock would be examined in off-site testing facilities and that no larger facilities would be constructed at Cínovec during that stage. This corpus records the testwork's location as a fact about where an operation happened. It undertakes no Australian exploration or prospectivity work, which remains out of scope. The claim is scoped TIMELESS because it records what a document states at a date, which does not expire. It is NOT a claim about the installation's present condition: no source read here speaks for today, and the corpus asserts no current status.
