MONTREAL, June 02, 2026 (GLOBE NEWSWIRE) -- Troilus Mining Corp. (TSX: TLG; OTCQX: CHXMF; FSE: CM5) (“Troilus” or the “Company”) is pleased to announce that Hydro-Québec and Quebec’s Ministère de l'Économie, de l'Innovation et de l'Énergie (“MEIE”) have approved the Company’s request for a 70 megawatts (“MW”) power allocation to support the development and operation of its copper-gold Troilus Project in north-central Quebec.

The allocation represents a major project de-risking milestone and reinforces Troilus’ strategic importance as one of Québec’s next large-scale critical minerals projects. The formal power request was submitted in early 2025, followed by continuous constructive engagement with Hydro-Québec and key government stakeholders. With permitting, detailed engineering, and project financing advancing in parallel, the allocation ensures that sufficient power will be available to support development as planned. Access to Québec’s low-carbon hydroelectric grid is expected to be a key contributor to the Project’s long-term emissions reduction objectives and provides Troilus with access to reliable, competitively priced renewable energy. Power infrastructure, including 107 kilometres of 161kV high-tension powerlines are already in place and connected to a substation at the Troilus site.

Justin Reid, CEO of Troilus, commented, “This confirmation from Hydro-Québec and the MEIE marks a crucial milestone for Troilus that meaningfully advances the project’s overall development readiness. Access to reliable hydroelectric power is a critical component of responsible mine development in Québec, and this allocation reflects the advanced stage and broader strategic importance of the Troilus Project within the province’s industrial and critical minerals landscape.Troilus is positioned to become a long-life project for Québec - one capable of delivering meaningful economic benefits, supporting domestic copper supply, and contributing to long-term regional development in Northern Québec. Securing this allocation further strengthens the foundation of the project and de-risks our path toward the next stage of development.”

The Troilus Project is the largest copper project currently at the permitting stage in Quebec and one of the largest undeveloped gold projects in Canada. The May 2024 Feasibility Study outlined a 22-year mine life and average annual production of 303,000 gold-equivalent ounces (“AuEq”) or 135.4 million pounds of copper-equivalent (“CuEq”), with peak production of 536,400 AuEq ounces. The Project is expected to generate significant economic benefits for the region, including approximately 1,000 direct jobs during construction and over 680 permanent jobs during operations.
