TROILUS SURPASSES 85% COMPLETION OF BASIC ENGINEERING WITH BBA; PROJECT ON SCHEDULE AND ADVANCING TOWARDS CONSTRUCTION READINESS

Troilus Gold Corp. has continued progress on the basic and detailed engineering of its copper-gold Troilus project, led by engineering partner BBA Inc., based in Montreal, Que.

Basic engineering of the project has now surpassed 85-per-cent completion, marking significant progress since the last engineering update provided on June 10, 2025. Following the completion of trade-off studies and process flowsheet definition earlier this year, the focus shifted to cost estimation, procurement and execution planning. Major deliverables -- including capital cost estimates, vendor evaluations and project execution plans -- are now well advanced, supporting a targeted construction decision in 2026.

Highlights of engineering progress to date

Procurement and technical evaluations:

• All requests for quotations (RFQs) have been issued to the market, supporting the transition toward execution planning as the project advances to cost definition and construction readiness.
• Technical and commercial assessments of major equipment and construction packages are nearing completion, with firm bids now received for key items, supporting vendor selection and refinement of capital cost estimates.
• Comprehensive project execution plans have been developed, outlining the framework for project delivery, including contracting strategy and construction sequencing.

Construction readiness and commissioning preparation:

• Layouts of construction facilities have been developed to optimize logistics and cost planning.
• Review of 3-D models for the project's process plant, dry comminution circuit and site infrastructure is over 30 per cent complete.
• Commissioning systems have been identified and sequenced to ensure a structured transition from construction to operations.

Justin Reid, chief executive officer of Troilus, commented: "We continue to make disciplined and measurable progress thanks to the expertise of our in-house team and BBA Consultants. Surpassing 85-per-cent completion of basic engineering marks an important step towards construction readiness and reflects the steady derisking of the Troilus project. With all RFQs issued and execution plans in place, we continue to advance and refine definitions around scope, costs and delivery strategy. We remain on track to complete basic engineering before year-end, positioning Troilus to advance seamlessly into detailed execution and towards a 2026 construction decision. BBA's deep knowledge of the Troilus site and our collaborative approach continue to be key drivers of this progress."
