Troilus wins Quebec Filon specialized support for strategic mining

MONTREAL, July 27, 2026 (GLOBE NEWSWIRE) -- Troilus Mining Corp. ( TSX: TLG; OTCQX: CHXMF; FSE: CM5 ) (“Troilus” or the “Company”), is pleased to announce that the Troilus Project has been selected by Québec's Minister of Natural Resources and Forests, the Honourable Kateri Champagne Jourdain, as one of the first projects to benefit from Filon, a specialized support service established by the Government of Québec to enhance government coordination and support the advancement of strategic mining projects through the provincial permitting process.

Announced as part of Québec's 2025-2031 Strategy for the Development of Critical and Strategic Minerals, Filon is designed to strengthen coordination among government ministries and agencies involved in the authorization process for qualifying projects. Through a dedicated team of mining specialists, the specialized support facilitates communication between project proponents and the government ministries and agencies responsible for issuing permits and authorizations, while maintaining Québec's rigorous environmental review framework.

In addition, the specialized support provided through the Filon initiative comes amid broader efforts by the Governments of Québec and Canada to improve the efficiency, clarity and predictability of regulatory processes for major projects. Earlier this week, the two governments announced a proposed "One Project, One Review" agreement aimed at harmonizing provincial and federal environmental assessments, reducing duplication while maintaining rigorous environmental oversight. Together, these initiatives reflect a growing commitment by the Governments of Québec and Canada to supporting the responsible development of strategic mineral projects.

The Troilus Project is among the first projects to receive specialized support through the Filon initiative, reflecting its strategic importance to Québec's critical minerals objectives and its advanced stage of development. Troilus submitted the Environmental and Social Impact Assessment ("ESIA") for its copper-gold Troilus Project in June 2025 and is currently advancing detailed engineering and project financing. In June 2026, the Project secured a 70 MW hydroelectric power allocation from Hydro-Québec and the Ministère de l'Économie, de l'Innovation et de l'Énergie ("MEIE").

Justin Reid, Chief Executive Officer of Troilus, commented, “We are honoured that the Government of Québec has recognized the Troilus Project as one of the first projects to benefit from the specialized support of Filon. As one of Québec's largest and most advanced copper-gold development projects, Troilus is well positioned to contribute to Québec's economic growth and long-term critical minerals strategy. We welcome initiatives that improve collaboration across government while maintaining a rigorous and transparent permitting process, and we appreciate the Government of Québec's continued commitment to advancing the responsible development of strategic mining projects in Québec.”

Kateri Champagne Jourdain, Québec's Minister of Natural Resources and Forests, commented, "Troilus is a large-scale mining project that will unlock Québec's significant gold and copper resources. The Project will help strengthen our economy, create lasting benefits for Northern Québec and reinforce Québec's position as one of the world's leading mining jurisdictions. Through Filon, the Company will benefit from specialized support to help advance its project."

Through Filon, Troilus will benefit from specialized support provided by mining experts through ongoing engagement with the Québec government ministries and agencies responsible for issuing the permits and authorizations required to advance the Project. Through this service, each project is assigned a dedicated expert whose role is to guide and direct companies through their administrative processes, identify bottlenecks and facilitate engagement with the relevant government ministries. This specialized support is expected to contribute to a more efficient and predictable permitting process and help advance the Project on schedule. Selection of the Troilus Project for specialized support through the Filon initiative represents another important milestone as the Company continues to advance toward a construction decision.
