First Phosphate President, Armand MacKenzie said: "This proposed investment by the Canadian Government is a most welcome development that will expand the economy of the region of Saguenay-Lac-St-Jean and bring quality jobs to the area. Most importantly, it will facilitate the commercialization of the region's natural resources, and especially First Phosphate's mineral properties that are greatly needed in the drive to onshore the LFP battery supply chain".

First Phosphate recently announced that it has finalized an industrial land option agreement (the "Agreement") with Port Saguenay. 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 high-purity phosphoric acid and iron powder for these LFP 18650 battery cells was produced using rare igneous anorthosite rock extracted from the First Phosphate Bégin-Lamarche property found at 70 km driving distance from 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.
