A Partnership Involving Arianne Phosphate Receives $1.4 Million For Work Associated With The LFP Battery

Press Release

SAGUENAY, QUEBEC – (March 3, 2025) – Arianne Phosphate (the “Company” or “Arianne”) (TSX VENTURE: 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 a Partnership involving Arianne and several other organizations has received a grant of $1.4M from the  Consortium de recherche et d’innovation en transformation métallique (“CRITM”).

The grant covers an initiative aimed at developing a new process for producing high-purity iron for use in Quebec’s lithium-iron-phosphate (“LFP”) battery cathode manufacturing process. As part of this effort, Arianne will be providing tailings containing magnetite (iron) from its Lac à Paul deposit that will be further processed and purified into the material necessary for these batteries.

In addition to the work being done as part of the Partnership, Arianne is advancing its efforts towards the development of a downstream facility to produce purified phosphoric acid (“PPA”), another necessary ingredient required for the LFP battery.  Both phosphate and high-purity iron were placed on Quebec’s critical mineral list in 2024 because of the rapid growth of the LFP battery.  Despite the importance of the LFP, the West currently has very little production capability with over 95% of these batteries being manufactured in China.  Initiatives such as this one, as well as other programs put in place are instrumental as the West looks to secure its own supply chains.  Arianne, through its ownership of the Lac à Paul project is an important part of this equation as Canada looks to create a complete battery ecosystem for Western needs.

Arianne would also like to congratulate its Chief Operating Officer, Raphael Gaudreault, on his recent election to the Board of Réseau MCS (Network for Critical and Strategic Minerals – www.critm.ca/mission-et-valeurs-du-reseau-mcs).  Mr. Gaudreault’s appointment recognizes both his individual knowledge and expertise, along with the importance Arianne will play in the critical mineral space on a go-forward basis.
