–Concentrate ideally suited for the specialty & LFP markets 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
