Where do First Phosphate Corp.’s shares trade and what are the ticker symbols?

First Phosphate Corp. is identified in the announcement as trading on NASDAQ under PHOS, the CSE under PHOS, the OTCQX under FRSPF and the FSE under KD0.

What does the peer-reviewed study of First Phosphate Corp.’s Bégin-Lamarche deposit examine?

The study examines the geological characterisation of the Mountain, North and South Zones of First Phosphate Corp.’s Bégin-Lamarche igneous phosphate deposit. Scientists from Queen’s University and Université du Québec à Chicoutimi conducted mineralogical, petrological and geochemical analysis.

What did the study find about the geological origin and continuity of First Phosphate Corp.’s phosphate zones?

The study found that apatite is the primary phosphatic mineralisation, confirming the magmatic origin and geological continuity of the phosphate-bearing zones across the Mountain, North and South Zones. The deposit is hosted in massif anorthosite and associated nelsonite and oxide-apatite-mafic to ultramafic rocks of the Lac-Saint-Jean Anorthositic Suite.

What phosphate concentrate grade did testing indicate at First Phosphate Corp.’s Bégin-Lamarche deposit?

Testing indicated concentrate levels around ~40% P₂O₅ at First Phosphate Corp.’s Bégin-Lamarche deposit. The announcement says this aligns above global averages for igneous phosphate concentrates and supports potential suitability for PPA production.

What did the study say about trace elements in First Phosphate Corp.’s phosphate mineralisation?

The study’s geochemical characterisation demonstrated low levels of deleterious trace elements in First Phosphate Corp.’s phosphate mineralisation. The announcement says these low concentrations enhance the potential for producing high-purity PPA suitable for lithium iron phosphate (LFP) cathode active material applications.

How could First Phosphate Corp.’s phosphate deposit support LFP battery production?

The announcement says the phosphate layers could be a potential high-purity source of phosphate for producing PPA, which is a critical precursor in manufacturing LFP battery cathode active material. It also says Québec igneous phosphate could support First Phosphate Corp.’s vertical integration strategy along the LFP battery supply chain.

What does First Phosphate Corp. say about potential open-pit mining at the Bégin-Lamarche deposit?

First Phosphate Corp.’s announcement says the geometry, thickness and near-surface occurrence of certain phosphate layers suggest favourable conditions for potential open-pit mining scenarios. Any such scenarios remain subject to further engineering and mine planning studies.

What broader exploration implications does First Phosphate Corp. identify from the study?

First Phosphate Corp. says the findings provide a foundation for exploring other igneous phosphate layers throughout the Québec anorthosite that may be suitable for LFP battery production. The announcement also says the results may apply to other phosphatic anorthosites globally, offering insights for high-purity phosphate resource development.

Who reviewed First Phosphate Corp.’s scientific and technical disclosure?

Steeve Lavoie, P.Geo., reviewed and approved First Phosphate Corp.’s scientific and technical disclosure in the announcement. He is the company’s Chief Geologist and a Qualified Person under National Instrument 43-101 – Standards of Disclosure of Mineral Projects.

What is ScienceDirect’s role in the First Phosphate Corp. announcement?

ScienceDirect, operated by Elsevier, is the platform on which the peer-reviewed study was published. The announcement describes it as a platform for peer-reviewed scientific, technical and health literature, including journal articles and book chapters.

What uncertainties does First Phosphate Corp. attach to its statements about the Bégin-Lamarche deposit?

First Phosphate Corp. says statements about potential mineralisation, geological merit, economic feasibility, future concentrate production, PPA suitability, potential open-pit mining and long-term development are forward-looking and are not guarantees of future performance. It identifies risks including exploration and development outcomes, access to capital and financing, economic and market conditions, permitting delays, project costs and schedules, commodity prices including P2O5, operational disruptions, and relationships with municipalities, First Nations, partners, suppliers and governments.

Announcement Summary

First Phosphate Corp. (NASDAQ: PHOS) (CSE: PHOS) (OTCQX: FRSPF) (FSE: KD0) announced publication of a peer-reviewed study of its Bégin-Lamarche Igneous Phosphate Deposit.

The study was published in Ore Geology Reviews on ScienceDirect and was authored by scientists from Queen’s University and Université du Québec à Chicoutimi (UQAC).
It characterizes the Mountain, North, and South Zones of the deposit within the 1.14 Ga Lac-Saint-Jean Anorthositic (“LSJA”) Suite.
The study identifies apatite as the primary phosphatic mineralization and reports geological continuity across the phosphate-bearing zones.
Testing indicates concentrate levels around ~40% P₂O₅, with the study reporting suitability for purified phosphoric acid (“PPA”) production.
The study reports low chlorine and other deleterious trace elements, supporting potential high-purity PPA for lithium iron phosphate (“LFP”) battery cathode active material.
Potential open-pit mining scenarios depend on further engineering and mine planning studies, based on layer geometry, thickness, and near-surface occurrence.

The company said the findings provide a foundation for exploring other igneous phosphate layers throughout Québec anorthosite. Results may apply to other phosphatic anorthosites globally. Steeve Lavoie, P.Geo., reviewed and approved the disclosure as Chief Geologist and a Qualified Person under NI 43-101.

Investor FAQs
