Arianne Phosphate (TSX-V: 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 the Government of Canada has approved the Company for contribution funding of up to $735,000 to support the Company’s ongoing work on processing phosphate rock and optimizing the purified phosphoric acid process, as previously disclosed (See Press Release dated October 6, 2025).

The funding, provided through Natural Resources Canada’s Critical Minerals Research, Development and Demonstration program, is part of an $80.3 million investment announced by Prime Minister Mark Carney at the 2025 G7 Leaders’ Summit to help build secure and resilient critical minerals supply chains in Canada and, announced by the Honourable Tim Hodgson, Canada’s Minister of Energy and Natural Resources on a visit to Arianne’s offices late last year.

Phosphate was added to the Canadian critical mineral list in 2024, joining the EU and was recently added to the American critical mineral list.  Arianne’s Lac à Paul is the only fully permitted phosphate mine in these respective jurisdictions.  Having spent $100M towards the mine’s advancement, the Company is now actively pursuing opportunities for the downstream production of PPA, a necessary ingredient for the lithium-iron-phosphate battery.  Aside from being the only fully permitted mine, Lac à Paul hosts one of the world’s largest greenfield phosphate deposit, which is igneous allowing its phosphate concentrate to be easily processed into PPA.

Arianne’s decision to pursue downstream opportunities will allow the Company to be a key supplier as the West looks to move away from China, which currently controls over 90% of the LFP market.  Beyond their use in EVs, LFPs are used in energy storage systems (“ESS”), a market growing rapidly both for home usage and their use in data centers, as applications like AI further accelerate demands.

“Investing in initiatives like Arianne Phosphate’s Technology Centre reinforces Canada’s position as a global leader in critical minerals. This commitment drives innovation, strengthens supply chain resilience, and creates good jobs for Canadians,” said the Honourable Tim Hodgson, Minister of Energy and Natural Resources. “By harnessing our natural resources responsibly, we are ensuring Canada remains at the forefront of the clean technology transition—advancing the priorities we set with our G7 partners in Kananaskis and building a cleaner, more secure future for all.”

“Canada’s support for Arianne Phosphate’s cutting-edge project demonstrates our commitment to building a secure and sustainable supply of critical minerals—key to advancing clean energy technologies. Investments like this create good jobs and strengthen our ability to source essential resources right here at home in Quebec for generations to come,” added Claude Guay, Parliamentary Secretary to the Minister of Energy and Natural Resources.

“Arianne appreciates Minister Hodgson and the Government of Canada’s support of our project,” said Marco Gagnon, Arianne Phosphate’s Executive Chairman of the Board.  “Initiatives like this are key if the West is going to build its own supply chain.  This investment helps Arianne to move the Lac à Paul project forward in a way that benefits the country and all of our stakeholders.  Phosphate is essential to LFP battery technology, global food and agricultural supply, it is used in pharmaceuticals and semiconductor production; our progress aligns closely with Canada’s vision of becoming a leader in critical minerals.”
