The permit received allows complete construction for all non-process buildings and site infrastructure and approves the general plant

layout and functions for the spodumene to lithium hydroxide conversion.

"It is a great day, and a remarkable milestone has been reached. We have already achieved an essential progress in securing

critical planning and pre-agreements for long lead items, and the basic engineering is done. The Bankable Project study completed

last year, and Front End Loading Study Level 3 is in its final stage and should be completed soon. We are strongly convinced that

this first partial license supports and accelerates further progress in the realization of this first of its kind project in

Europe

battery-grade lithium hydroxide. Therefore, the conversion plant will be an important contributor to in a European battery value

chain.
