Saguenay, Quebec--(Newsfile Corp. - October 2, 2024) - First Phosphate Corp. (CSE: PHOS) (OTC: FRSPF) (FSE: KD0) ("First Phosphate" or the "Company") is pleased to announce that a peer-reviewed research note has been published by Queen's University ("Queen's") and Université de Québec à Chicoutimi ("UQAC") entitled:

The study is divided into two main sections and compares igneous phosphate ore bodies around the world, including the Company's Bégin-Lamarche property, as to their ore grades, beneficiated phosphate concentrate levels and mining operations where applicable.

  1. Comparisons of global igneous ore grades and beneficiated igneous ore

Only a small portion of the worldwide phosphate ore (~10%; Pufahl and Groat, 2017) is supplied from igneous rock from Russia, South Africa, Brazil, and Finland. These igneous phosphate deposits are mostly from the Khibiny Alkalic Igneous Complex (Notholt, 1979) and the Kovdor Phoscorite-Carbonatite Complex (Ivanyuk et al., 2016) from the Kola Peninsula in Russia, the Siilinj?rvi Carbonatite Complex in Finland (Decrée et al., 2020), the Phalaborwa (Palabora) Igneous Complex in South Africa (Gómez-Arias et al.2022), and the Alto Paranaíba Alkaline Province in Brazil (Silva et al., 2023) (Fig. 1). These igneous deposits are from silica-undersaturated alkali intrusions and carbonatites.

The average P2O5 contents of phosphate ore from igneous rocks from major deposits in the four major countries (Russia, Finland, South Africa, and Brazil) exhibit significant variations (4.0-17.2 wt.%; Table A2).

The igneous phosphate ore found at First Phosphate's Bégin-Lamarche property in Quebec, Canada is mostly from nelsonite and oxide-apatite-mafic- ultramafic rocks in massif anorthosite from the Grenville Province (geological province). The P2O5 of the ultramafic rock ranges from 2.6 to 15.0 wt.%. The average P2O5 grading of the phosphate is 6.01%. Testing suggests that the phosphate ore from this deposit could produce a high-quality phosphate concentrate with a P2O5 content of ~40.9 wt.% (Table 1), which is above the global average P2O5 of marketable phosphate concentrates produced from igneous ore from other countries (36.9 wt.%; Table 1).
