Successful Battery-Grade pilot programme for Cinovec Lithium Project
November 9, 2023 - European Metals Holdings Limited (ASX AIM: EMH) (“European Metals” or the “Company”) is pleased to announce the results of the Lithium Chemical Plant (“LCP”) pilot programme, confirming the robustness of the Cinovec LCP process flowsheet and providing a strong foundation for the execution of the Cinovec Project.
Highlights
- Pilot programme has confirmed industrial viability of the LCP process flowsheet.
- Exceptionally clean battery grade lithium carbonate (>99.9%) produced with single-stage purification (bicarbonation) of crude lithium carbonate.
- Pilot programme crude lithium carbonate confirmed at 99.7% purity, greater than battery grade (99.5%) in the carbonate precipitation step without any additional processing.
- Work to produce battery grade lithium hydroxide monohydrate is underway.
- The pilot programme processed ore fully-representative in all respects of the run-of-mine for the first seven years of mining planned at Cinovec, including average grade and expected rock-type mix from the bulk mining.
Executive Chairman, Keith Coughlan, said:
“The confirmation of the exceptionally clean nature of the Cinovec Lithium Carbonate resulting from the pilot programme is further proof of the tremendous importance of the Cinovec Lithium Project for the whole of the EU. The Lithium Carbonate produced by the simplified flowsheet has the ability to be a major contributor to the EU’s lithium security. The Cinovec Project is well positioned to be a major supplier of battery grade lithium products to the strategically important European car industry to ensure that they are able to compete on the global stage.
The pilot programme data is now being used to confirm design and engineering for the ongoing Definitive Feasibility Study (DFS) being completed by DRA Global and which remains on-track for completion in the current quarter, and also for the post-DFS detailed design.
European Metals, in developing the Cinovec Lithium Project, is well positioned for the rising demand in battery materials in the EU. The Cinovec project is the largest hard rock lithium project in the EU and Europe as a whole and is centrally located on the Czech Republic’s border with Germany.”
Pilot Programme
The pilot programme, which took place at ALS Laboratories in Perth, WA, set out to confirm the LCP flowsheet which was the subject of the Company’s ASX announcement of 31 October 2022 “Simplified Extraction Process delivers exceptionally-clean battery-grade lithium product with improved economics” and to produce sufficient marketing samples for potential offtakers to test in their own laboratories.
The pilot programme has achieved these objectives without necessitating any further development of the LCP process flowsheet.
In doing so, the pilot programme has provided extensive data throughout all of the LCP process steps. This data contributes to the confirmation of design and engineering for both the ongoing Definitive Feasibility Study (“DFS”) and the post-DFS execution of the Project.
Next Stage of Development of Cinovec
The DFS for battery-grade Lithium Carbonate remains on-track for completion in 4Q 2023. Subject to confirmation of the pilot programme work for battery grade Lithium Hydroxide, a decision on the battery grade end-product (carbonate vs hydroxide) for the Cinovec Project is expected to be made in early 2024. This will enable design engineering to proceed enabling the Project to come into production in the shortest possible time frame and includes engagement with long lead equipment OEMs to ensure that the timeline is expedited.
High-Grade Lithium End-Products
The LCP flowsheet pilot programme produced the following crude and battery-grade lithium carbonate products, compared with the published global standard specification, YS/T 582-2013 and the crude and battery grade lithium carbonate products produced in the Cinovec locked cycle tests reported in the Company’s ASX/AIM announcement of 31 October 2022 “Simplified Extraction Process delivers exceptionally-clean battery-grade lithium product with improved economics”.
It can be seen that in respect of the majority of the limits specified by standard YS/T 582-2013, being the elements or chemical species of interest to cathode manufacturers, for both the crude and the battery grade lithium carbonate products, the semi-industrial scale continuously piloted results are superior to the results from the locked cycle tests which were bench-scale tests of a batch processing nature.
These results confirm the robustness of the Cinovec LCP process flowsheet and provide a strong foundation for the execution of the Cinovec Project.
In both the LCT and the piloted battery-grade lithium carbonate, the end-product was produced in a single bicarbonation step. This places an important limitation on opex expenditure in the final processing stages, avoiding the need for repeated bicarbonation steps or for blending of technical grade lithium carbonate produced with battery grade lithium carbonate, to just achieve battery grade with an assay average, a common step in some lithium carbonate plants.

BACKGROUND INFORMATION ON CINOVEC
PROJECT OVERVIEW
Cinovec Lithium Project
Geomet s.r.o. controls the mineral exploration licenses awarded by the Czech State over the Cinovec Lithium Project. Geomet has been granted a preliminary mining permit by the Ministry of Environment and the Ministry of Industry. The company is owned 49% by EMH and 51% by CEZ a.s. through its wholly owned subsidiary, SDAS. Cinovec hosts a globally significant hard rock lithium deposit with a total Measured Mineral Resource of 53.3Mt at 0.48% Li2O, Indicated Mineral Resource of 360.2Mt at 0.44% Li2O and an Inferred Mineral Resource of 294.7Mt at 0.39% Li2O containing a combined 7.39 million tonnes Lithium Carbonate Equivalent (refer to the Company’s ASX release dated 13 October 2021) (Resource Upgrade at Cinovec Lithium Project).
An initial Probable Ore Reserve of 34.5Mt at 0.65% Li2O reported 4 July 2017 (Cinovec Maiden Ore Reserve – Further Information) has been declared to cover the first 20 years mining at an output of 22,500tpa of lithium carbonate (refer to the Company’s ASX release dated 11 July 2018) (Cinovec Production Modelled to Increase to 22,500tpa of Lithium Carbonate).
This makes Cinovec the largest hard rock lithium deposit in Europe and the fifth largest non-brine deposit in the world.
The deposit has previously had over 400,000 tonnes of ore mined as a trial sub-level open stope underground mining operation.
On 19 January 2022, EMH provided an update to the 2019 PFS Update, conducted by specialist independent consultants, which indicates a post-tax NPV of USD1.938B and a post-tax IRR of 36.3% and confirmed that the Cinovec Project is a potential low operating cost producer of battery-grade lithium hydroxide or battery grade lithium carbonate as markets demand. It confirmed the deposit is amenable to bulk underground mining (refer to the Company’s ASX release dated 19 January 2022) (PFS Update delivers outstanding results). Metallurgical test-work has produced both battery-grade lithium hydroxide and battery-grade lithium carbonate at excellent recoveries. Cinovec is centrally located for European end-users and is well serviced by infrastructure, with a sealed road adjacent to the deposit, rail lines located 5 km north and 8 km south of the deposit, and an active 22 kV transmission line running to the historic mine. As the deposit lies in an active mining region, it has strong community support.
The economic viability of Cinovec has been enhanced by the recent strong increase in demand for lithium globally, and within Europe specifically.
There are no other material changes to the original information and all the material assumptions continue to apply to the forecasts.
BACKGROUND INFORMATION ON CEZ

LITHIUM CLASSIFICATION AND CONVERSION FACTORS
Lithium grades are normally presented in percentages or parts per million (ppm). Grades of deposits are also expressed as lithium compounds in percentages, for example as a percent lithium oxide (Li2O) content or percent lithium carbonate (Li2CO3) content.
Lithium carbonate equivalent (“LCE”) is the industry standard terminology for, and is equivalent to, Li2CO3. Use of LCE is to provide data comparable with industry reports and is the total equivalent amount of lithium carbonate, assuming the lithium content in the deposit is converted to lithium carbonate, using the conversion rates in the table included below to get an equivalent Li2CO3 value in percent. Use of LCE assumes 100% recovery and no process losses in the extraction of Li2CO3 from the deposit.
Lithium resources and reserves are usually presented in tonnes of LCE or Li.
The standard conversion factors are set out in the table below:
