CINOVEC PROJECT UPDATE – BATTERY GRADE LITHIUM HYDROXIDE PRODUCED – CLARIFICATION ON TEST-WORK PROCESS
· Flowsheet successfully developed and tested for the production of lithium hydroxide from Cinovec ore.
· A potential production rate in excess of 25,000 tpa lithium hydroxide has been demonstrated to be possible utilising a robust process route proven in the lithium production sector.
· A formal update of the project PFS reflecting the production of lithium hydroxide is underway and will be completed within the next 6 weeks.
European Metals Holdings Limited (“European Metals” or “the Company”) is pleased to provide a project update highlighting the outcomes from a recently completed engineering assessment of the flowsheet and subsequent testwork aimed at demonstrating the ability to produce lithium hydroxide from Cinovec ore. The move by the Company to develop a process for the production of lithium hydroxide from the Cinovec project is in response to market forces that continue to move Czech and European manufacturers towards the production of advanced technology batteries.
The engineering assessment and associated testwork were conducted on aspects of the hydrometallurgical portion of the flowsheet of the Preliminary Feasibility Study (PFS) reported on 19 April 2017 (PFS confirms potential low-cost lithium carbonate producer).
A series of tests were completed in recent months by Dorfner Anzaplan in Germany looking initially at the direct production of lithium hydroxide from leach liquors and subsequently testing a more traditional route of converting lithium carbonate through to lithium hydroxide.
While both process routes were successful in producing battery grade lithium hydroxide, assessment of the relevant process risks indicated that the more robust flowsheet involved the production of battery grade lithium carbonate followed by conversion to battery grade lithium hydroxide. The composition of the material produced compared with a typical industry specification is detailed in the table 1 below.

Cinovec Lithium/Tin Project
European Metals, through its wholly owned subsidiary, Geomet s.r.o., controls the mineral exploration licenses awarded by the Czech State over the Cinovec Lithium/Tin Project. Cinovec hosts a globally significant hard rock lithium deposit with a total Indicated Mineral Resource of 372.4Mt @ 0.45% Li2O and 0.04% Sn and an Inferred Mineral Resource of 323.5Mt @ 0.39% Li2O and 0.04% Sn containing a combined 7.18 million tonnes Lithium Carbonate Equivalent and 263kt of tin reported 28 November 2017 (Further Increase in Indicated Resource at Cinovec South). An initial Probable Ore Reserve of 34.5Mt @ 0.65% Li2O and 0.09% Sn 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 reported 11 July 2018 (Cinovec Production Modelled to Increase to 22,500tpa of Lithium Carbonate).
This makes Cinovec the largest lithium deposit in Europe, the fourth largest non-brine deposit in the world and a globally significant tin resource.
The deposit has previously had over 400,000 tonnes of ore mined as a trial sub-level open stope underground mining operation.
EMH has completed a Preliminary Feasibility Study, conducted by specialist independent consultants, which indicated a return post tax NPV of USD540m and an IRR of 21% reported 19 April 2017 (PFS Confirms Potential Low Cost Lithium Carbonate Producer). It confirmed the deposit is amenable to bulk underground mining. Metallurgical test work has produced both battery grade lithium carbonate and high-grade tin concentrate at excellent recoveries. 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. As the deposit lies in an active mining region, it has strong community support.
The economic viability of Cinovec has been enhanced by the recent strong increase in demand for lithium globally, and within Europe specifically.
There are no other material changes to the original information and all the material assumptions continue to apply to the forecasts.
