SIGNIFICANT INCREASE IN PLANNED LITHIUM PRODUCTION

European Metals Holdings Limited (ASX & AIM: EMH, OTCQX: EMHXY and EMHLF) ("European Metals" or the "Company") is pleased to announce a significant increase in the planned annual production of lithium chemicals from the Cinovec Project ("Cinovec" or "the Project").

Highlights

·      Planned production of battery-grade lithium hydroxide monohydrate increased by 42% to 41,658 tpa or 36,670 tpa of battery-grade lithium carbonate.

·      Planned run-of-mine ore production increased by 42% taking the Project production rate from 2.25 mtpa to 3.20 mtpa, without processing plant head grade, the Life of Mine or plant recovery being significantly impacted.

·      This planned increase in production enables the Project to benefit from significant economies of scale which will be confirmed in the Definitive Feasibility Study ("DFS") now due for completion in mid-2025.

Keith Coughlan, Executive Chairman, commented: "This work on the production increase was carried out by Bara as part of its Mining DFS and is another example of the important work being done to improve the economics of the Cinovec Project during the extended timeframe for the DFS. This significant increase in planned lithium output will lead to additional recognition of how important the Cinovec Project is and the role the Project will play in enabling the EU to reach its goals of lithium self-sufficiency by 2030."

Increase in Planned Mine and Battery Grade End-Product Lithium Chemicals Production

The assessment of production capacity capabilities for the Project has now been completed with the result being that the run-of-mine production ("ROM") has been increased from 2.25 million tonnes per annum ("mtpa") to 3.2 mtpa.

The substantial increase in ROM has resulted in an increase in the planned production of lithium hydroxide monohydrate from 29,385 tonnes per annum ("tpa") to 41,658 tpa or 36,670 tpa of lithium carbonate without the need to increase the size of footprint of the underground mine at surface.  This 42% increase in ROM production is expected to result in considerable economic benefits to be gained due to the economies of scale flowing through to the lithium chemical plant.

In the past the critical constraint on mine production capacity for the Project was the size of the proposed Dukla processing plant site, at 24 hectares. The Prunéřov EPR1 site which is now to be used is 36 hectares and enables increased ROM production.

Bara Consulting, the mining adviser to the Project, was instructed to review options for an increase in ROM production. This review was at Concept Study level, building on the previous mining Pre-Feasibility Study ("PFS") published on 19^th January 2022 and subsequent DFS-level of work as part of the overall DFS.

The limitations placed on ROM capacity review by the Project team were that the mine portal area could not increase in size or change position and that the box-cut and twin decline system would remain the same as designed for the PFS and as a result not materially impact the environmental footprint.

The results of increasing planned mine production levels when compared with the PFS mine production levels are set out in the table below:

The mine plan for the new 3.2mtpa ROM planned production level is the same as the mine plan for the PFS producing 2.25mtpa, except that it is mined faster and Inferred JORC Resources are brought into production in the last eight years of mining (Years 21 to 28), including three ramp-down years). No Inferred Resources are included in the mine plan in Years 1 to 20.

Assumed Lithium Recovery Levels

The lithium recovery to concentrate used in this Study represents the recovery from a Front-End Comminution and Beneficiation circuit ("FECAB") design which is 100% flotation. As detailed in the Company's announcements of 31^st July 2024 and 27^th November 2024, the repeatable lithium recoveries for un-deslimed flotation achieved in bench-scale testing are >94%. The FECAB recovery rate of 91.5% used in the table above incorporates allowances for full scale-up / industrial plant performance.

DFS Status Update

As noted in the Cinovec Project Update announcement of 27^th November 2024, results of the DFS are expected to be released in mid-2025. The increased planned ROM and battery grade lithium product levels will not impact this timeline.

European Metals, in developing the Cinovec Lithium Project, is well positioned to meet the rising demand for battery materials in the European Union ("EU") and to support the EU's objectives to secure supply of Critical Minerals including lithium within the EU. The Cinovec Project is the largest hard rock lithium project in the EU and Europe and is centrally located on the Czech Republic's border with Germany. The project has excellent ESG credentials underpinning the production of battery grade lithium hydroxide and/or carbonate with low CO₂ emissions in a global context.

This announcement has been approved for release by the Board.

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/ AIM 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/ AIM 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. It confirmed the deposit is amenable to bulk underground mining (refer to the Company's ASX/ AIM 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. In February 2023 DRA Global Limited ("DRA") was appointed to complete the Definitive Feasibility Study ("DFS").

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. The deposit lies in an active mining region.

The economic viability of Cinovec has been enhanced by the recent push for supply security of critical raw materials for battery production, including the strong increase in demand for lithium globally, and within Europe specifically, as demonstrated by the European Union's Critical Raw Materials Act (CRMA).

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:
