FULL ENVIRONMENTAL IMPACT ASSESSMENT SUBMITTED FOR CINOVEC LITHIUM PROJECT

HIGHLIGHTS

·    Full Environmental Impact Assessment (EIA) for the Cinovec Lithium Project submitted to the Czech Ministry of the Environment on 31 December 2025

·    Submission completes the two-stage EIA process following screening-stage assessment lodged in 2025

·    EIA submission satisfies a key condition of the EU Just Transition Fund grant

·   DFS recently confirmed a 26+ year mine life and forecast production of ~37,500tpa battery-grade lithium carbonate

·     Project remains on track to meet the Just Transition Fund requirement for EIA approval by 30 June 2026

European Metals Holdings Limited (ASX and AIM: EMH, OTCQX: EMHXY/EMHLF) ("European Metals" or the "Company") is pleased to advise that the full Environmental Impact Assessment (EIA) for the Cinovec Lithium Project (Project) was formally submitted to the Czech Ministry of the Environment (Ministry) on 31 December 2025.

The submission completes the two-stage EIA process, following lodgement of the screening-stage assessment earlier in 2025, and represents a key regulatory milestone for the Project.

This EIA covers the entire Cinovec development and supports the outcomes of the recently completed Definitive Feasibility Study (DFS), which confirmed Cinovec as a long-life, large-scale European lithium project with a 26+ year mine life and forecast production of approximately 37,500 tonnes per annum of battery-grade lithium carbonate[1].

Review Process

The Ministry of the Environment will now commence its formal review of the EIA. The documentation is expected to be made publicly available for consultation later this quarter, with the Ministry to determine the timing for public submissions and hearings.

Scope of the EIA

The EIA identifies and assesses potential environmental impacts associated with the Project and outlines proposed mitigation and management measures, including monitoring requirements. It considers physical, biological and socio-economic factors from an environmental protection perspective and incorporates the technical modelling required under Czech and EU regulations.

EU Just Transition Fund Condition Met

Submission of the EIA satisfies a key condition of the EU Just Transition Fund (JTF) grant

awarded to the Cinovec Project[2].

In April 2025, the Czech selection panel approved CZK 800 million (approximately US$36

million at the time) in grant funding. Conditions of the grant require:

ü Submission of the full EIA by 31 December 2025 

·      Approval of the EIA by the Czech Ministry of the Environment by 30 June 2026

Executive Chairman Keith Coughlan said:

"Submitting the full EIA is an important step forward for Cinovec and follows the completion of the DFS, which confirmed the scale, longevity and strategic importance of the Project. This strategic importance has been definitively unpinned by the ~EUR 360 million grant approved to the project recently.

Environmental approvals are critical to development in the Czech Republic, and meeting the EIA submission deadline was a key requirement under the Just Transition Fund. The Geomet team has done an excellent job delivering this work within the required timeframe and keeping the Project on schedule."

ENDS

This announcement has been approved for release by the Board.

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 54.4Mt at 0.58% Li₂O , Indicated Mineral Resource of 378.23Mt at 0.41% Li₂O and an Inferred Mineral Resource of 309.49Mt at 0.39% Li₂O containing a combined 7.45 million tonnes Lithium Carbonate Equivalent (refer to the Company's ASX/ AIM release dated 23 December 2025) (Cinovec DFS Confirms Long-life Battery Grade Lithium Carbonate Producer Strategically Positioned to supply European EV and Energy-storage Sectors).

A Proven and Probable Ore Reserve of 54.4Mt at 0.58% Li₂O has been declared to cover the first 26 years mining at an output of 37,500tpa of lithium carbonate (refer to the Company's ASX/ AIM release dated 23 December 2025) (Cinovec DFS Confirms Long-life Battery Grade Lithium Carbonate Producer Strategically Positioned to supply European EV and Energy-storage Sectors).

The Definitive Feasibility Study (DFS) confirmed the economic viability of the Cinovec Project with steady-state production of 37,500 tpa of battery-grade lithium carbonate (Li₂CO₃), representing ~5.2% of EU demand in 2030 and sufficient for >900,000 50kWh EV batteries annually.  Cinovec will have a 28+ year operating life, underpinned by a 748Mt Resource @ 0.19% Li₂O and a 55.4Mt Ore Reserve, with expansion optionality (refer to the Company's ASX/ AIM release dated 23 December 2025) (Cinovec DFS Confirms Long-life Battery Grade Lithium Carbonate Producer Strategically Positioned to supply European EV and Energy-storage Sectors).

This makes Cinovec 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 (refer to the Company's ASX/ AIM release dated 25/26 March 2025) (Cinovec declared a Strategic Project under EU Critical Raw Materials Act) and a Strategic Deposit by the Czech Government (refer to the Company's ASX/ AIM release dated 7 March 2025) (Cinovec declared Strategic Deposit by Czech Government).

Cinovec has received recent impetus from the EU and the Czech Government in the form of grants of USD36 million from the EU Just Transition fund (refer to the Company's ASX/ AIM release dated 28 April 2025) (USD 36 million Just Transition Fund Grant Approved for Cinovec Project) and up to EUR360 million by the Czech Government (refer to the Company's ASX/ AIM release dated 7 March 2025) (Approval of up to €360 Million  Czech Government Grant).

The deposit has previously had over 400,000 tonnes of ore mined as a trial sub-level open stope underground mining operation.

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 Cinovec processing plant comprises of a Front-End Comminution and Beneficiation circuit (FECAB) and Lithium Chemical Plant circuit (LCP) in combination producing Lithium Carbonate end products and will be located on the Prunéřov 1 Power Station site located approximately 59km by rail from the Cinovec mine site (refer to the Company's ASX/ AIM releases dated 26 April 2024 (New Lithium Plant Site Expected to Improve Project Permitting and Economics) and 27 November 2024 (Cinovec Project Update)).

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:
