Arianne Phosphate Selected to Benefit from the Québec Government’s

Specialized Filon Support Service

SAGUENAY, Québec, Aug. 06, 2026 -- 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 its Lac à Paul phosphate project is one of the first

projects selected to benefit from the “Filon” service. The “Filon” support service was established by Québec’s Ministère des

Ressources naturelles et des Forêts (MRNF).

This initiative aims to strengthen government coordination and support the advancement of strategic mining projects within the

provincial authorization process. Filon’s objective is to facilitate exchanges between mining proponents and the ministries and

agencies responsible for issuing authorizations and permits, in accordance with the Québec Strategy for the Development of

Critical and Strategic Minerals 2025-2031.

This support also forms part of the efforts of the governments of Québec and Canada to improve the efficiency, clarity and

predictability of the regulatory processes applicable to major projects. In this regard, the two governments recently announced

a proposed agreement based on the principle of “one project, one assessment, one decision”, which aims to reduce overlaps

in environmental assessments while maintaining rigorous environmental protection standards. Together, these initiatives

demonstrate a growing willingness to support the responsible development of projects related to critical minerals.

“We are honoured that the Lac à Paul project is among the first projects selected to benefit from the specialized support

offered by Filon,” said Marco Gagnon, Executive Chairman of Arianne Phosphate. “This recognition confirms the strategic

nature of our project for Québec and its ability to address the growing global security of supply issues regarding phosphate.

Lac à Paul is a world-class asset, located in a stable and responsible jurisdiction, and will support the Western value chains

linked to both agriculture and LFP batteries. We believe that better-coordinated support will help advance the project more

efficiently, while maintaining the rigour and transparency of the authorization process. We would like to thank the Government

of Québec for its commitment to supporting projects that can generate lasting economic benefits for the Saguenay–Lac-Saint-

Jean region and for Québec as a whole.”

From the Minister of Natural Resources and Forests, Kateri Champagne Jourdain:

“The personalized Filon support is an additional lever to propel mining projects for the benefit of Québec’s development and its

regions. The Lac à Paul project will foster job creation in the Saguenay–Lac-Saint-Jean region and strengthen Québec’s

contribution to phosphate supply chains. We are proud to support companies such as Arianne Phosphate, through Filon, to

accelerate mining projects and stand out on the world stage!”

Fully audited and supported by a feasibility study, the Lac à Paul project is one of the largest undeveloped phosphate deposits

in the world. Located in the Saguenay–Lac-Saint-Jean region, it aims to produce a high-purity apatite concentrate for the

fertilizer markets and purified phosphoric acid (PPA), notably used in lithium-iron-phosphate (LFP) batteries. These markets

are complementary: they rely on the same high-quality resource and make it possible to maximize the value of the project

while meeting distinct and strategic needs.

Western dependence on the supply of phosphate is concentrated in regions of the world that have been geopolitically

challenging. The development of a Canadian source of high-purity phosphate represents a strategic benefit and, the Lac à Paul

project will help reduce this dependence while strengthening the resilience of North American supply chains while supporting

both food security and the energy transition.
