Arianne produces phosphate concentrate at 41.5% P2O5

Executive Summary

• Arianne Phosphate successfully produced a phosphate concentrate grading 41.5 % P₂O₅ with a 0.02 % minor element ratio (MER), the highest purity ever achieved by the company.
• The results were generated in a customer‑trial program conducted by Corem, adding an extra processing step to Arianne’s existing metallurgical flow sheet and yielding 1.2 t of high‑grade product.
• The breakthrough supports Arianne’s strategy to supply purified phosphoric acid (PPA) for the food/agricultural sector and lithium‑iron‑phosphate (LFP) battery market, enhancing its position as a critical‑minerals supplier outside China.

Key Details

• Product Quality: 41.5 % P₂O₅; MER = 0.02 %, among the world’s highest‑quality phosphate concentrates.
• Test Scale: Customer trial produced 1.2 tonnes of concentrate meeting the above specifications.
• Process Innovation: Added an additional processing step beyond Arianne’s optimized metallurgical process, surpassing all prior test work.
• Strategic Importance: High‑purity concentrate improves feedstock for purified phosphoric acid (PPA), a key input for LFP batteries used in EVs and energy storage systems.
• Market Context: Anticipated shortage of PPA; growing demand for LFP batteries worldwide, with current production heavily concentrated in China (>95 %).
• Project Relevance: Demonstrates the value proposition of the Lac à Paul project—only shovel‑ready, permitted phosphate development in the Americas and Western Europe.
• Stakeholder Interest: Results expected to aid discussions with potential partners seeking secure critical mineral supplies.
• Regulatory & Funding Context: Mention of recent Canadian government funding (press release Jan 7 2026) that will further advance project development.
