Saguenay, Quebec - Newsfile Corp. - March 13, 2024 - First Phosphate Corp. (CSE: PHOS) (OTC: FRSPF) (FSE: KD0) ("First Phosphate" or the "Company") is pleased to announce that it has signed a memorandum of understanding ("MOU") with Groupe Goyette ("GG") of Saint-Hyacinthe, Quebec for the accommodation of the Company's logistical footprint at the Hébertville-Station intermodal facility in the Saguenay-Lac-St-Jean region of Quebec, Canada.

"This agreement is important to our future customers because it would create a rapid truck-to-rail on and off ramp between our mining and industrial facilities in Saguenay and the auto-industry heartland of North America," says CEO John Passalacqua. "Our clients in the battery technology industry for electric vehicles ("EVs") and energy storage will be demanding and will require reliable, just-in-time transportation assurances."

The terms of the agreement include:

• First Phosphate and GG are to work towards determining the rail line options for the movement of the Company's products and supplies to and from Saguenay, Quebec and the rest of North America through the Hébertville-Station, Quebec intermodal facility owned and operated by GG.

• First Phosphate and GG are to work towards determining the transportation, handling and storage facility expansion requirements for the Hébertville-Station, Quebec intermodal facility in order to accommodate the flow of the Company's products and materials to and from Hébertville-Station, Quebec and the rest of North America.

• Specific emphasis is to be placed on rapid truck-to-rail intermodal capabilities and flow of the Company's products and supplies from Hébertville-Station, Quebec in the Saguenay and the rest of North America and specifically to the automobile industry heartland in the Windsor-Detroit corridor of North America.

• GG is to join the First Phosphate project team and begin to determine the best overall project-based logistics necessary to integrate the Company's product and supply flows with the Hébertville-Station, Quebec intermodal facility. Fleet electrification and reduction of carbon footprint are key considerations in project development.

• First Phosphate and GG will work together to make the economic, social and job creation benefits of their arrangement known to the Quebec, Canadian and United States governments.
