Episode notes

In this episode, we sit down with John Passalacqua, CEO of First Phosphate (CSE: PHOS), to discuss one of the most overlooked segments of the energy transition: the phosphate supply chain for LFP batteries. As investors increasingly focus on lithium, nickel, and cobalt, phosphate has quietly emerged as a potential bottleneck for lithium iron phosphate (LFP) battery production outside of China.

First Phosphate's Investor Presentation: https://firstphosphate.com/FirstPhosphateDeck_english.pdf

Drawing on our research and recent work in the battery materials sector, we explore why igneous phosphate resources—such as First Phosphate's Bégin-Lamarche project in Quebec—may play a critical role in supplying purified phosphoric acid (PPA), a key precursor for LFP cathode materials. John walks us through the six-step integrated mine-to-cathode value chain, the distinctions between igneous and sedimentary phosphate, and why high-purity phosphate is essential for battery-grade chemistry.

We also examine the company's business model, drilling progress, feasibility timeline, offtake strategy, infrastructure advantages, and how First Phosphate is positioning itself to support North America's growing demand for LFP-based battery energy storage systems (BESS). The conversation includes a detailed look at the company's PEA economics, permitting pathway, government engagement, and strategic partnerships across the supply chain.

For investors tracking the electrification trend, critical minerals, and the rapid shift toward LFP chemistry in stationary storage and EVs, this discussion provides context on a market segment that has received limited attention but may prove strategically important over the coming years.

Topics Covered
