European Metals Holdings said drilling results at its Cinovec lithium and tin project in the Czech Republic had confirmed its confidence in the ore body.
Five of eight planned wells had been drilled, with the remainder due to start after the end of the snow season.
Highlights included intersecting 129.3m averaging 0.51% lithium oxide in one hole and intersecting 108m averaging 0.45% lithium oxide and 0.11% tin in another.
'The results confirm our confidence in the robustness of the ore body and we are particularly encouraged by the higher than expected tin grades in hole CIS-13,' managing director Keith Coughlan said.
'These holes form part of the feasibility study that is now underway.'
'The study includes the production of lithium hydroxide from bench scale work that is in process and due for completion next month.'
'At that point the company expects to be able to release the updated pre-feasibility study results.'
