ARIANNE PHOSPHATE NAMES PIERRE FITZGIBBON AS A STRATEGIC ADVISOR TO THE COMPANY

Pierre Fitzgibbon will be joining Arianne Phosphate Inc. as a strategic adviser. In his role as strategic advisor, Mr. Fitzgibbon will provide guidance to Arianne's management in regard to business strategy and help target potential partners for the development of the project.

Mr. Fitzgibbon, until September, 2024, served as the Quebec Minister of Economy, Innovation and Energy, Minister Responsible for Regional Economic Development, and Minister Responsible for the Montreal Region. During his time in this role, Mr. Fitzgibbon was a strong advocate for the mining industry in the province and played an active part in advancing Quebec as a major player in the battery materials and critical minerals space. Before entering politics, Mr. Fitzgibbon held roles with several prominent financial firms, including private equity firm Walter Capital Partners (managing partner) and National Bank Financial (vice-chairman and chief financial officer). Mr. Fitzgibbon also held several operating positions through his career, including president and chief executive officer of Atrium Innovations as well as Domtar and Peerless Carpet.

"I have watched the Arianne project advance since its early days when I was a member of the board and beyond," said Mr. Fitzgibbon. "As many know, I have long been a believer in the future of batteries and understand that Quebec has a key role to play in the North American/Western ecosystem. Further, I have always supported the notion of putting a structure in place to allow Quebec to transform its own critical mineral supply into the necessary downstream materials. When it comes specifically to phosphate, Arianne should play a key role as the industry increasingly looks to using LFP [lithium-iron-phosphate] batteries and I believe that I can help the company as it looks to make its project become a reality."

"Pierre and I have known each other for many years, including during his time at Arianne, where we had a strong working relationship," said Brian Ostroff, president of Arianne Phosphate. "I look forward to us working together again and know that Pierre's experience and network will help accelerate Arianne's discussions with potential partners as we look to bring our project to fruition. Pierre has a very strong business sense, he is known internationally, and he has experience in advancing critical mineral projects here in Quebec."

In 2024, phosphate was added to both Quebec and Canada's critical mineral lists. Arianne owns the Lac a Paul phosphate project in Quebec, Canada. The project hosts the world's largest greenfield phosphate deposit, has easy access to existing infrastructure and is fully permitted. Due to the rare igneous nature of the deposit, Arianne can produce a very high-purity, low-contaminant phosphate concentrate that is easily transformed into purified phosphoric acid (PPA).

Beyond its use in fertilizer, phosphate and, in particular, PPA, is a necessary ingredient for the LFP battery. The LFP battery today is the most prominent of batteries due to its use in both electric vehicles and energy storage systems and its continued rapid adoption will require more of the input ingredients. Today, China represents over 95 per cent of all LFP production, and, as the West looks to secure its own supply chain, Arianne's project will be a necessity.

Regarding his role as strategic adviser, the company has granted Mr. Fitzgibbon 300,000 options. These options entitle Mr. Fitzgibbon to purchase 300,000 common shares of the company until March 13, 2027, at a price of 14 cents per share, this being the closing price of the company's shares on the trading day preceding the date of the grant. The options are subject to a vesting period and are also subject to regulatory approval. Mr. Fitzgibbon will not be receiving any cash compensation.
