Troilus Advances Procurement and Detailed Engineering as Project Execution Readiness Builds

Executive Summary

• Troilus Mining has advanced its wholly owned Troilus Project into the Detailed Engineering phase following the completion of Basic Engineering in March 2026.
• The company has fully mobilized detailed engineering teams, issued over 40 bid packages for major equipment and infrastructure, and completed initial selections for key water treatment and site support systems.
• Independent third-party reviews of the process plant design and capital cost methodology were completed with no material issues, and a geotechnical field drilling program has been finished to support foundation and site layout design.

Key Details

• Detailed Engineering is fully mobilized across process plant, infrastructure, site layout, 3D modelling, and procurement support.
• Over 40 bid packages issued for tender or under technical/commercial evaluation, covering major process equipment, infrastructure, site services, and enabling works.
• Initial enabling infrastructure selections completed for key water treatment and site support systems.
• Major process equipment package advancing through final technical and commercial evaluation and selection.
• Geotechnical field drilling program completed to support foundation design, site layout, infrastructure planning, and earthworks.
• Independent third-party reviews of process plant design, Basic Engineering assumptions, and capital cost methodology completed with no material issues identified.
• Site readiness activities ongoing, including camp expansion planning, site infrastructure upgrades, water management systems, communications/technology upgrades, and preparation for future contractor mobilization.
• Project scale context: Large-scale 50,000 tonne-per-day open-pit operation supported by a May 2024 Feasibility Study for a 22-year mine life.

Notable Quotes

• Justin Reid, Chief Executive Officer: “Since completing Basic Engineering earlier this year, Troilus has continued to build momentum across the next phase of project development. Detailed Engineering is now fully mobilized, and our team is advancing the technical and commercial work required to support key equipment, infrastructure and construction planning decisions. For a large-scale 50,000 tonne-per-day operation, this early work is critical to maintaining schedule discipline, strengthening cost certainty and ensuring that major equipment decisions are properly integrated into final engineering and execution planning. The progress we are making reflects the strength and focus of our team, and our disciplined approach to reducing execution risk ahead of a formal construction decision.”
