[{"type":"text","content":"Arianne Phosphate Successfully Produces Phosphoric Acid on a Continuous Basis\nSAGUENAY, Quebec, May 14, 2026 (GLOBE NEWSWIRE) -- Arianne Phosphate Inc (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 phosphoric acid has been successfully produced on a continuous basis using its high-purity phosphate concentrate. This accomplishment marks the first time phosphoric acid has been continuously produced in the Province from a Quebec-sourced apatite concentrate in over 130 years. This work was done in partnership with Corem and with the support of Natural Resources Canada (NRCan). “The importance of phosphate continues to grow while at the same time supply chains are increasingly threatened by geopolitical events,” said Raphael Gaudreault, COO of Arianne Phosphate. “This breakthrough is yet another example of the quality of our phosphate concentrate and demonstrates the opportunity for a fully localized phosphate supply chain here in Quebec, Canada, that could end a century of dependence on imported rock. Further, much of the world is now questioning its supply chains and this work shows how Arianne will be an important and trusted partner to the West for this critical material. This work strengthens Canada’s critical minerals strategy, secures domestic feedstock and positions Quebec as the North American leader in the green energy transition.” During tests performed at Corem, the Company produced roughly 1.5 tonnes of phosphoric acid on a continuous basis over a one-week period. Due to the nature of Arianne’s phosphate concentrate, the phosphoric acid produced is easily upgraded to a purified phosphoric acid (see Press Release dated April 9, 2026), the material required for the LFP battery industry as well as high-performance fertilizers, pharmaceuticals and semiconductor production. Additionally, Arianne’s phosphate concentrate requires considerably less sulphuric acid to produce its phosphoric acid, another significant advantage as almost 50% of sulphur flows through the Strait of Hormuz. “For many years the supply of phosphate was taken for granted with few...
