ARIANNE PHOSPHATE ENHANCES THE ROLES OF TWO KEY MANAGEMENT POSITIONS

DAN: TSX-V (Canada)
JE9N: FSE (Germany)
DRRSF: OTCQX (USA)

SAGUENAY, QC, Sept. 11, 2025 /CNW/ - Arianne Phosphate (the "Company" or "Arianne") (TSXV: DAN) (OTCQX: 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 the Company has appointed Marco Gagnon as Executive Chairman and will also be creating the management position of "Head of Strategic & Business Initiatives" with this role being filled by Brian Ostroff, moving over from his current role of President.

Marco Gagnon has served as Arianne's Director and Chairman of the Board since 2011 and 2023 respectively. Mr. Gagnon's move to Executive Chairman will increase his involvement in key activities with the Company's management team which is relatively small and is currently being pushed towards capacity as it moves its Lac à Paul project towards development. Mr. Gagnon, a 30-year senior mining professional with large and small mining companies, founded Adventure Gold in 2007 (subsequently sold to Probe Gold in 2016) and currently serves as a Technical Advisor to Probe Gold Inc. "I am excited to take on my new responsibilities and very pleased to work with the team in place in advancing Arianne's Lac à Paul phosphate project. The release of our prefeasibility report in June 2024 regarding a downstream purified phosphoric acid plant has generated a significant increase in discussions regarding our project. Today it is all about getting the project into development. We have been very active in our conversations with potential partners to help us do so and Arianne's repositioning of the Company's management is being done to focus on this endeavour. Being successful will unlock tremendous value to our stakeholders and shareholders and provide the West with this much needed commodity." said Mr. Gagnon. 

In addition to Mr. Gagnon's move to Executive Chairman, Arianne has created the position of Head of Strategic and Business Initiatives to meet the Company's increasing discussions centered around its partnership and financing activities and to address a significant uptick in inbound inquiries. Given Mr. Ostroff's background in mergers & acquisitions (partner at a global M&A firm) and capital markets finance (partner at a resources-focused hedge fund), as well as his experience in senior management at Arianne, the Board has appointed him to this new role. Operationally, this will now allow Mr. Ostroff to focus almost exclusively on this new role. "Aside from our previously announced deal with a large mining company in October 2024, the projected tightness in the purified phosphoric acid market has opened significant opportunities as both industry and financial players look to secure the product they need and the economic benefit that comes with it. Added to this is the growing awareness that the West is looking to onshore its needs for critical mineral supply and fabrication. Arianne has the world's largest greenfield phosphate deposit, and our igneous phosphate allows for the easy production of a cleaner PPA. The feasibility stage mining project is large, ambitious and relatively unique being permitted and shovel ready. The addition of like-minded partners will go towards getting the project developed and unlocking the substantial economic and strategic benefits that come with it. In my new role, I will be able to fully dedicate my efforts towards making this a reality." said Mr. Ostroff.

Phosphate historically has been understood as an agricultural commodity necessary for fertilizers. Currently North America, along with most other jurisdictions are reliant on phosphate imports sourced from the Middle East and North Africa. Both Russia and China are also active in phosphate production. There is no substitute for phosphate and without its use, farm yields would be unable to support food requirements. Demand for phosphate has grown at roughly 2% annually.

Aside from its use in agriculture, phosphate demand, specifically phosphoric acid, has been increasing drastically because of the widespread adoption of the lithium-iron-phosphate ("LFP") battery. The LFP battery has become the predominant battery in electric vehicles as well as energy storage systems, with demand for these batteries set to grow significantly in the coming years. LFP batteries require purified phosphoric acid ("PPA"), a product that ideally requires a high-quality phosphate concentrate as its feedstock. Demand for battery-grade PPA is expected to double over the next 5-10 years. China currently produces over 90% of all LFPs adding an additional challenge as the West is adopting these batteries at an increasing rate while looking to diversify its supply chains away from China. Recognizing these dynamics, both Quebec and Canada joined the EU in adding phosphate to their critical mineral lists.

Arianne Phosphate owns the Lac à Paul phosphate project, the world's largest greenfield phosphate deposit. Situated in Quebec, Canada, the project benefits from being in a geopolitically safe jurisdiction as the West looks to secure its own supply of this critical mineral. Arianne's deposit being igneous, it allows to produce a high purity phosphate concentrate which is easily transformed into PPA. The Company has spent over $100 million over the last 15 years advancing the project through exploration, feasibility studies, metallurgical testing and ultimately permitting. Today, Lac à Paul stands as the most advanced phosphate project in the West. The Company also published a prefeasibility study showing the immense benefits of adding a downstream segment to its business.
