CLARIFICATION OF CONCEPT STUDY RESULTS AND RETRACTION OF PRODUCTION TARGETS

European Metals Holdings Limited (ASX & AIM: EMH, OTCQX: EMHXY and EMHLF) ("European Metals" or the "Company") provides the following update to its announcement from 20 December 2024 relating to the results of a Concept Study for the Cinovec Project ("Cinovec" or "the Project").

Highlights

·      On 20 December 2024 the Company announced the results of a Concept Study evaluating potential production and processing scenarios for the Cinovec Project. The study assessed potential increases in run-of-mine ("ROM") ore processing capacity compared to the Prefeasibility Study ("PFS"), without significantly impacting processing plant head grade, Life of Mine, or plant recovery. If supported and confirmed in the Definitive Feasibility Study ("DFS"), these scenarios would represent an increase to the possible production previously announced in the PFS of 29,386tpa (refer to the Company's ASX/ AIM release dated 19 January 2022) (PFS Update Delivers Outstanding Results).

·      The potential increase in production remains conceptual and the economic viability of the project based on the variables considered is currently unknown. However, the potential increase in production would enable the Project to benefit from significant economies of scale which are expected to be confirmed in the DFS, now due for completion in mid-2025.

·      Shareholders must not rely on the original Concept Study announcement dated 20 December 2024. There are no changes to the production targets, assumptions, or modifying factors contained in the PFS.

Keith Coughlan, Executive Chairman, commented: "This work on the Concept Study, conducted by Bara as part of its Mining DFS, highlights the ongoing efforts of the Company to assess opportunities for improving the economics of the Cinovec Project during the extended timeframe for the DFS. We are pleased that the potential to increase the project's planned capacity has been evaluated as technically achievable, reinforcing the significance of the Cinovec Project and its anticipated role in helping the EU achieve its lithium self-sufficiency goals by 2030."

Proposed Increase in Battery Grade End-Product Lithium Chemicals Production Capacity

The assessment of potential production capacity increases for the Project has now been completed at concept study level. The Concept Study indicates that a potential increase in ROM production capacity may be achievable, subject to further evaluation in the upcoming DFS.

The proposed increase in ROM capacity is expected to be achievable without the need to increase the size of footprint of the underground mine at surface.  This increase in ROM production capacity is expected to result in considerable economic benefits due to the economies of scale flowing through to the lithium chemical plant. Further work will be required to assess the economic benefits of any potential increase in capacity as part of the ongoing DFS.

Bara Consulting, the mining adviser to the Project, was instructed to review options for an increase in the ROM production targeted by the Project. The review was done at concept study level, building on the previous mining PFS published on 19 January 2022 and subsequent DFS-level of work as part of the overall DFS.

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 which easily supports and enables the increased ROM production objective.

Constraints placed on the 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 mine plan for the conceptual study-level assessment is essentially the same as the mine plan for the PFS, producing 2.25 mtpa, except that it assumes a faster mining rate and incorporates Inferred JORC Resources in the last eight years of mining (Years 21 to 28, including three ramp-down years). No Inferred Resources were included in the Concept Study mine plan in Years 1 to 20.

The Concept Study scope includes mining of the Cinovec deposit by sub-level longhole open stoping methods, with backfill, however with an expanded fleet of larger equipment to achieve the increased mining rate. Muck handling circuits previously designed were considered suitable for the expanded production scenario. ROM ore is to be transported 9km to the Dukla site which is now planned to be a trans-shipment site for outbound ROM ore and inbound mine backfill material.

ROM ore is to be transported from Dukla by rail to the new and expanded processing plant site at Prunéřov, where it is processed to LiOH.H₂0. Appropriate capital provisions for the expanded mining operation as well as an expanded processing facility have been made in the Concept Study.

Tailings are to be disposed of at the Doly Nástup Tušimice open-pit coal mine site previously planned (4km from the processing plant site), which was assessed as adequate for the increased disposal capacity required. Lithium Chemical Plant residue is now to be transported by backhaul via rail then rope conveyor to the mine portal site where it is prepared as paste backfill and pumped underground.

The Measured and Indicated Resource base previously reported adequately supports the proposed increase in production, however with consequently reduced life of mine. Positive project economics were demonstrated at Concept Study levels of confidence for Mining Inventory derived from Measured and Indicated Resources only. However, project economics as well as life of mine were suitably improved by the inclusion of Inferred Resources in the later years of the mine plan, which were therefore included in the Concept Study evaluation and will thus be carried into the ongoing DFS study workplan.

Note there is a low level of geological confidence associated with Inferred mineral resources and there is no certainty that further exploration work will result in the determination of indicated mineral resources or that the mining production proposed in Years 21 to 28 of the Concept Study will be realised. However, as the Cinovec mineral deposit is massive, the Project shows a good track record of upgrading Inferred Resources to Indicated and Measured categories.

Assumed Lithium Recovery Levels

The lithium recovery to concentrate used in this Concept Study represents the recovery from a Front-End Comminution and Beneficiation circuit ("FECAB") design which is now 100% flotation-based. As detailed in the Company's announcements of 31 July 2024 and 27 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 Concept Study incorporates allowances for full scale-up / industrial plant performance.

DFS Status Update

As noted in the Cinovec Project Update announcement of 27 November 2024, results of the DFS are expected to be released in mid-2025. The proposed increased in ROM and battery grade lithium product tonnages for the Project (as contemplated by the Concept Study) 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 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:
