Arianne Phosphate delivers purified phosphoric acid samples

SAGUENAY, Quebec, July 09, 2026 (GLOBE NEWSWIRE) -- Arianne Phosphate Inc (the “Company” or “Arianne”) (TSX VENTURE: DAN; OTCQB: DRRSF; FRANKFURT: JE9N ), a development-stage phosphate mining company, advancing it’s Lac à Paul project in Quebec’s Saguenay-Lac-Saint-Jean region, is pleased to announce that it has shipped samples of purified phosphoric acid (“PPA”) to potential customers for testing. The samples shipped were successfully produced at pilot scale (see Press Release dated June 18, 2026 ) by combining Arianne’s high-purity, low-contaminant phosphate concentrate with Travertine Technologies’ (the “Partnership”) proprietary process for producing PPA while allowing for the recapture of the sulphuric acid used in the process. Internal testing of the PPA produced met specifications required for the product’s use in various technical applications including LFP batteries.

Following this milestone, samples have now been sent to potential customers for their assessment. These first samples of PPA were sent to companies covering three separate industries: a CAM (cathode active material) producer for ultimate use in LFP batteries, a diversified industrial chemicals producer that uses PPA for water treatment and pulp & paper applications and a specialized liquid fertilizer producer. The testing that will be performed is the first step in the qualification process required in securing commercial contracts for the product. “With demand running high for new sources of PPA, there was a lot of interest in receiving our samples,” said Brian Ostroff, Head of Strategic & Business Initiatives at Arianne Phosphate. “Surging demand from newer applications such as the LFP, coupled with the existing demands from the pharmaceutical, agricultural, electronics and food industries have made the procurement of PPA vital.

At the same time, geopolitical tensions have squeezed access to important materials and caused a re-think of traditional supply chains. Arianne currently has the only permitted phosphate mine in the West and understands how strategically important its development is. To that end, we continue to make significant progress with groups like Travertine and other ‘like-minded’ government, corporate and financial partners to advance the development of our Lac à Paul project.” By sending samples to companies in diverse industries, the Arianne-Travertine partnership can demonstrate its ability to address supply concerns that are affecting many businesses.

Further, these companies are North American based and looking for Western-sourced materials. Concurrent with the testing of the PPA that will be occurring over the coming weeks, the Partnership will be advancing its work towards a demonstration plant (see Press Release dated April 21, 2026 ) that will be able to produce greater quantities of material for additional companies to work with. Ultimately, Arianne is looking to provide the West with the PPA it needs to meet growing demands and, can do so from geopolitically advantaged Canada. “Purified phosphoric acid is a critical commodity with fast growing demand outpacing global production,” said Travertine’s CEO, Laura Lammers. “Our proprietary sulfur, solvent-free process produces high-purity phosphoric acid but with a lower cost and a much smaller environmental impact.

Canada holds a wealth of strategically critical phosphate resources yet has not mined phosphate since 2013 nor produced downstream phosphate products since 2019. We believe Arianne Phosphate is best positioned to fill this void with its Lac a Paul deposit. In partnership, Travertine and Arianne will advance Canadian phosphate production in a way that best respects and protects Canada’s uniquely pristine natural environment while addressing the West’s urgent needs for purified acid.” About Arianne Phosphate: Arianne Phosphate (“Arianne Phosphate Inc.”) ( www.arianne-inc.com ) is developing the Lac à Paul phosphate deposits located approximately 200 km north of the Saguenay/Lac St. Jean area of Quebec, Canada.

These deposits will produce a high-quality igneous apatite concentrate grading 39% P 2 O 5 with little or no contaminants (Feasibility Study released in 2013). About Travertine:  Travertine was founded in 2022 to solve one or the most pressing problems in the mining industry: producing vital elements without creating mountains of waste. Their proprietary electrochemical technology completely converts phosphate ore concentrate into valuable products – phosphoric acid, cementitious materials, and co-produced critical elements – closing the loop between the extraction and construction industries for cleaner chemical production. Their gypsum-free, solvent-free process will become the standard for next generation, cleaner purified phosphoric acid production.
