The Agreement covers lands where the Company plans to develop a phosphoric acid plant using advanced clean technology from Prayon SA of Belgium and to be implemented by international engineering firm Ballestra S.pA. of Italy. The lands at Port Saguenay offer strategic benefits and a competitive position, including:

• Direct rail and vessel access to North American and global markets, especially to the company's European offtakers;

• Access to large-scale industrial infrastructure, utilities and expansion lands; and

• Eventual vertical integration between upstream phosphoric acid and downstream LFP battery material production.

The Agreement was signed in Montreal on July 18, 2025 at the premises of the Wallonia Export & Investment Agency ("AWEX") and in Saguenay, at Port Saguenay.

The critical minerals and intermediary products for such LFP battery cells would eventually be transported to European and North American offtakers via Port Saguenay.
