European Metals Holdings Limited Announces Preliminary Results for Design Optimisation of Lithium Chemical Plant for the Cinovec Project European Metals Holdings Limited announced preliminary results for the design optimisation of the lithium chemical plant ("LCP") for the Cinovec Project. Potential to reduce consumption of major reagents by USD 51m per annum(based on Definitive Feasibility Study ("DFS") reagent pricing. Potential to reduce power consumed in the LCP post-roast and leach filtration by more than 25% or USD 3.4m per annum (based on DFS power pricing. Taken together,these reductions represent the potential to increase the pre-tax NPV8 of USD 1.455bnestablished in the December 2025 DFS, however the exact quantum of such increase based upon the revised assumptions will only be known once the Project DFS is updated. As part of Geomet's post-DFS project review, the LCP circuit team reviewed the potential for reconfiguration of the LCP process flowsheet without introducing any new untested unit processes. The DFS flowsheet is extremely effective in separating lithium from the other Group I cations in the pregnant leach solution, in the lithium phosphate precipitation stage. However, this process is a strong consumer of tri-sodium phosphate ("TSP") and, indirectly, caustic soda ("NaOH") used to regenerate the TSP, as well as sulphuric acid used to dissolve the lithium phosphate for onwards processing. The proposed reconfiguration of the LCP flowsheet results in the majority of solubilised lithium reporting directly to crude lithium carbonate precipitation, with the balance of lithium and the majority of other Group I cations being processed by the lithium phosphate precipitation reactor in a side-stream /recycle configuration. The reconfigured flowsheet has been modelled in SysCAD, utilising testwork data and partition coefficients from locked cycle testwork programmes from 2022 and 2024.SysCAD is a process simulation platform used across the minerals industry to model and validate hydrometallurgical flowsheets prior to physical testwork and engineering design. The principal process improvements in the flowsheet optimisation from SysCAD modelling are: 80% reduction in annual run-of-plant caustic soda usage, from 18.8 tph to 3.8 tph; 65% reduction in annual run-of-plant sulphuric acid usage, from 14.3 tph to 5.0 tph; 54% reduction in annual run-of-plant anhydrous sodium sulphate output, from 25.2 tph to 11.7 tph. In addition to the above process improvements, the optimised flowsheet modelling forecasts a slight improvement in LCP lithium recovery, from 90.8% in the DFS to 91.1%.(Refer to the Company's ASX/AIM release dated 23 December 2025) (Successful Completion - Cinovec Definitive Feasibility Study) for DFS LCP lithium recovery. The potential reduction in power consumption in the LCP brought about by the proposed changes has been assessed by a factored estimation approach, utilising known power consumptions for unit processes in the DFS. The potential power consumption assessed should be considered to be indicative only, until testwork is completed and the Project DFS has been updated. The LCP flowsheet optimisation proposed has been reviewed in a fatal flaw analysis by Dr. Stephen La Brooy of Ausenco Services Pty Ltd. Dr. La Brooy's review has concluded that the proposal may be expected to be viable subject to confirmation through testwork and has made testwork recommendations to confirm the SysCAD modelling, the extent of reagent reduction possible, the potential increase in expected lithium recovery and maintenance of battery-grade status of the end product. The principal recommendation is to run a new set of locked cycle tests of the full LCP flowsheet, followed by updating the SysCAD model and then re-running locked cycle tests for a final confirmation of expected chemistry throughout the flowsheet. At the point at which process stream compositions and recoveries stabilise in the locked cycle testwork programme to the satisfaction of independent reporting chemical engineers, the DFS is expected to be updated.
