First Phosphate Obtains High Purity 40.2% Apatite Concentrate in Metallurgical Testwork Based on Lac à L’Orignal Property in Quebec, Canada

Saguenay, Quebec–(Newsfile Corp. – March 20, 2023) – First Phosphate Corp. (CSE: PHOS) (FSE: KD0) (« First Phosphate » or the « Company« ) is pleased to announce that it has obtained Metallurgical Testwork results on mineralization sourced from its Lac à l’Orignal Property in the region of Saguenay-Lac-St-Jean, Quebec, Canada. The testwork was completed by an independent laboratory, SGS Canada Inc., Quebec City, Quebec, and dated March 13, 2023. The full report is available at: https://firstphosphate.com/projects/assets.

The results from the batch and locked cycle tests were used to prepare an overall mass balance for the proposed flowsheet. The overall mass balance showed that the flowsheet could recover 91.4% of the apatite to a concentrate containing 40.2% P2O5.

Preliminary upgrading testwork on the ilmenite and magnetite streams achieved an ilmenite concentrate grading 39.3% TiO2 and a magnetite concentrate grading 69.0% Fe (99.2% Fe2O3). Further testwork is recommended to optimize the ilmenite circuit.

« We are pleased with the results of our high purity apatite recovery which has the potential to allow us to create a large amount of purified phosphoric acid for the production of LFP batteries, » says First Phosphate President, Peter Kent. « Our secondary recovery of ilmenite is equally important in that its upgrading may allow us to create the iron sulphate required as another important ingredient in the production of LFP batteries. The magnetite remains a potential tertiary recovery of value. We are now able to proceed towards a beneficiation pilot plant ahead of schedule. »

The metallurgical testwork program was undertaken on a composite of 75 fluoroapatite half drill cores from the Lac à l’Orignal Deposit with the objective of recovering and upgrading the apatite (removing silicates, ilmenite, magnetite, etc.) to produce high grade concentrate feed for phosphoric acid production to be used in the production of LFP cathode active material. The composite sample had a head grade of 5.55% P2O5.
