Geomet backs tunnel kiln for Cinovec lithium processing in Czechia

European Metals says Geomet has given in principle approval to replace Cinovec's two gas fired rotary kilns with a single tunnel kiln that can run on gas or electricity, with testwork indicating comparable or better lithium recovery at lower temperatures.

Why it matters: Cinovec is Europe's flagship hard rock lithium project, and a cheaper, lower energy processing route that could run on partner CEZ's green power improves the economics the project must show to financiers, though the savings are not yet quantified.

Data as of Company announcement reported October 22 to 23, 2026. The approval is in principle and the heating configuration has not been selected; no savings figure was quantified in this announcement. Earlier testwork in July 2026 pointed to a potential capital saving of about 112 million dollars, which is not repeated as a current estimate.

European Metals Holdings has backed a redesign of the Cinovec lithium project’s processing plant, with project company Geomet giving in principle approval to replace two gas fired rotary kilns with a single tunnel kiln. Testwork indicates comparable or improved lithium recovery at lower temperatures, with expected reductions in processing plant capital and operating costs and lower energy requirements.

The proposed kiln could be heated with either gas or electricity, potentially allowing Cinovec to operate entirely on green power supplied by project partner CEZ, although the final heating configuration has not been selected. The tunnel kiln operates at a controlled solids temperature of about 850 degrees Celsius, reducing energy consumption and the maintenance and vitrification risks associated with rotary kilns.

The project scale is the reason a flowsheet choice matters. Cinovec, in the Czech Republic, is held by Geomet, in which European Metals holds 49 percent and CEZ holds 51 percent through a subsidiary. The definitive feasibility study confirmed a mine life of more than 26 years with forecast production of about 37,500 tonnes a year of battery grade lithium carbonate, and the deposit carries a declared ore reserve of 54.4 million tonnes at 0.58 percent lithium oxide.

Two cautions belong with the headline. European Metals has not quantified the savings in this announcement, so the financial impact remains an engineering expectation rather than a revised cost forecast, and earlier testwork pointing to a potential capital saving of about 112 million dollars dates from July. Separately, a recent Geomet cash call funded in full by CEZ trimmed European Metals’ indirect interest, with an option to restore it that must be exercised by mid November. The kiln decision and the funding decision now run on the same clock.
