Arianne Phosphate Successfully Produces a Higher Grade/Lower Contaminant Phosphate Concentrate

Press Release

SAGUENAY, QUEBEC – (January 22, 2026) – Arianne Phosphate (the “Company” or “Arianne”) (TSX VENTURE: DAN; OTCQB: DRRSF; FRANKFURT: JE9N), a development-stage phosphate mining company, advancing the Lac à Paul project in Quebec’s Saguenay-Lac-Saint-Jean region, is pleased to announce that it has received results from a recently completed program aimed at improving grade while lowering the contaminants (non P₂0₅ elements) of its phosphate concentrate. The completed program resulted in the production of a higher content, higher purity phosphate than ever previously achieved by the Company and at a grade of 41.5% P₂0₅ with a 0.02% of Minor Element Ratio (“MER”), would be among the world’s highest quality concentrates.

The tests, initiated by a customer trial, were conducted by Corem, an innovation Center offering a range of specialized research services to develop and optimize key mineral processing procedures. The customer trial produced 1.2 tonnes of phosphate concentrate grading 41.5% of P₂0₅ with a 0.02% MER. The process added an additional step beyond Arianne’s already optimized metallurgical process and surpassed any of the Company’s previously performed metallurgical test work.

These results are significant as the quality of the phosphate concentrate input greatly affect the ability to produce purified phosphoric acid (“PPA”), an ingredient currently required in the food and agricultural industry and, a necessary input for the lithium-iron-phosphate (“LFP”) battery. The LFP has become the most widely used battery world-wide as growth in the EV and ESS (Energy Storage Systems) has generated a significant increase in demand for the inputs required to produce these batteries. In the case of PPA, many industry analysts see a pending shortage and the requirement for new production to come onstream, especially outside of China which currently accounts for over 95% of all LFP production.

“This outcome is extremely encouraging and underscores the strategic importance our Lac à Paul project,” said Raphael Gaudreault, Chief Operating Officer of Arianne Phosphate.  “These results continue to show how our phosphate concentrate will allow us to become a major supplier to the battery market and benefit from the enhanced economics that come with it. It is important to note, Lac à Paul is the only shovel-ready permitted project in the Americas and Western Europe and we continue to receive interest from would-be partners as they look to secure their necessary inputs. These results should be very helpful to those discussions.”

Since 2024, Quebec, Canada and the United States have all placed phosphate on their respective critical mineral lists, joining the EU. Arianne has established itself as the leader in the West’s quest to build out a critical minerals supply-chain separate from China. With 15 years and roughly $100 million spent advancing its Lac à Paul project, the Company is working with potential partners to advance the project and go downstream. The recent receipt of funding support from the Government of Canada (see Press Release dated January 7, 2026) will help advance the Companies efforts to do so and, be a major producer of PPA.
