Saguenay, Quebec - Newsfile Corp. - December 18, 2024 - First Phosphate Corp. (CSE: PHOS) (OTCQB: FRSPF) (FSE: KD0) ("First Phosphate" or the "Company") is pleased to announce that, yesterday, the Company signed two long-term offtake agreements with creditworthy offtake partners (the "Purchasers") with respect to its future productions to take place in Saguenay-Lac-St-Jean, Quebec, Canada, thereby de-risking its future projects and enhancing their prospective financing.

In addition, the Company is now entering the next phase of discussions with the Pekuakamiulnuatsh First Nation (the "First Nation") regarding a possible financial involvement in the Company, as provided for in the collaboration agreement signed by the First Nation and the Company on April 9, 2024.

"We congratulate First Phosphate on this offtake agreement," says Pekuakamiulnuatsh First Nation Chief, Gilbert Dominique. "It is with optimism that we welcome the achievement of this important milestone, and we look forward to pursuing the next stage of our discussions with First Phosphate."

"First Phosphate is achieving its goals as it continues to build a trusting relationship with the First Nation which is committed to supporting the development of the project in a way that respects its values," says John Passalacqua, CEO of First Phosphate.

The definitive terms of the offtake agreements shall be finalized in separate agreements to be entered into between the parties. The agreements contain termination rights by the Purchasers if the first delivery of product is not made by a certain date unless the parties agree to an extension as well as other normal course termination provisions. The commencement of the industrial operations proposed by the Company are subject to a number of conditions, including permitting and financing which the Company continues to work towards diligently.
