First Phosphate Drill Results Confirm World-Class Potential of Its Bégin-Lamarche Phosphate Property

A pre-recorder discussion of results with CEO, John Passalacqua and Chief Geologist, Gilles Laverdiére, is available at: https://youtu.be/7CQO7HGCyYI.

Highlights:

• Discovery of two main zones with multiple open pit accessible phosphate-bearing layers.

• The Northern Zone consists of four main layers with a length of 375 m each and which average at least 60 m in thickness. The layers appear open in all directions.

• The Southern Zone comprises at least two layers up to 1,500 m long that average 100 m in thickness.

• The mineralized layers have been drilled to a depth of at least 200 m.

• Both zones are found within a larger 2,500 m strike zone.

"These drill results confirm our expectations of the size, grade and world-class phosphate potential of our Bégin-Lamarche property located at only 75 km from the deep-sea Port of Saguenay," commented First Phosphate President Peter Kent. "With another light drill program, we should be in a position to initiate a 43-101 resource estimate for this property later this year."

"Phosphate projects require good grades, access to infrastructure and, above all, proximity to port in order to be successful and to be able to make it into production without lengthy delays," said First Phosphate CEO, John Passalacqua. "Bégin-Lamarche has it all starting with some of the best phosphate grades and direct paved-road access to the deep-sea port of Saguenay at only 75 km away."

A second 2,000 m drill program is being planned for the Northern Zone of the Bégin-Lamarche property. The objective of this infill program will be to drill the known phosphate layers to a 100 x 100 m grid in order to be able to commission a 43-101 resource estimate for the Bégin-Lamarche property later this year.

The Northern Zone

Thirteen drill holes completed in the Northern Zone identified four phosphate-bearing layers. The layers average 60 m true width and are at least 500 m long. The layers appear to be open in all directions. Two holes intersected the mineralized layers to a depth of at least 200 m. Two of the four layers show grades in excess of 7.0% P₂O₅ (phosphate). The four layers show an average grade of 6.2% P₂O₅. Results are shown in Figure 2 and Table 1. The outline of the layers is presented in Figure 1.

Southern Zone

Seven drill holes in the Southern Zone identified two layers containing phosphate. Both layers averaged 100 metres true width. The primary layer is at least 1,500 m long. Drilling showed that the mineralized layers extend to a depth of at least 150 m. The average grade of the layers in the Southern Zone is 4.7% P₂O₅ (phosphate). Results are presented in Figure 3 and Table 2. The outline of the layers is presented in Figure 1.

Quality Assurance / Quality Control

The sampling of, and assay data from, the drill core is monitored through the Company's implementation of a quality assurance - quality control (QA-QC) program designed to the CIM Mineral Exploration Best Practices Guidelines.

Drill core (NQ size) is logged and samples are selected by Laurentia Exploration Inc. geologists and sawn in half with a diamond saw at the project site. Half of the core is retained at the site for reference purposes. Sample intervals may vary from 0.5 to 3 metres in length depending on the geological observations. Half-core samples are packaged and sent by ground transportation in sealed rice bags to an independent laboratory, Activation Laboratories Ltd. of Ancaster, Ontario (ISO/IEC 17025:2005 with CAN-P-1579). The core samples are crushed up to 80% passing 2mm (10 mesh), riffle split 250 g and pulverized (mild steel) to 95% passing -200 mesh. Each sample is analyzed for whole rock analysis (code 4B) for 10 major oxides and 7 trace elements by lithium metaborate/tetraborate fusion and analysis by ICP-OES. The laboratory has its own QA/QC protocols where blanks and internal standards are inserted alternatively every 10 samples. A formal chain-of-custody procedure was adopted for security of samples until their delivery at the laboratory.

About First Phosphate Corp.

First Phosphate is a mineral development company fully dedicated to extracting and purifying phosphate for the production of cathode active material for the Lithium Iron Phosphate ("LFP") battery industry. First Phosphate is committed to producing at high purity level, at full ESG standard and with low anticipated carbon footprint. First Phosphate plans to vertically integrate from mine source directly into the supply chains of major North American LFP battery producers that require battery grade LFP cathode active material emanating from a consistent and secure supply source. First Phosphate holds over 1,500 sq. km of royalty-free district-scale land claims in the Saguenay-Lac-St-Jean Region of Quebec, Canada that it is actively developing. First Phosphate properties consist of rare anorthosite igneous phosphate rock that generally yields high purity phosphate material devoid of high concentrations of harmful elements.
