Project overview and development status

• Eskay Creek is advancing as a large-scale, high-grade gold and silver mine with robust cash flow and profitability projections, targeting 450,000 gold equivalent ounces annually in years 1-5 and a projected after-tax free cash flow of C$1.5 billion per year in that period.

• Construction is 49% complete as of February 2026, with initial production scheduled for Q2 2027 and commercial production by Q3 2027.

• The project is fully permitted, with all major environmental and mining permits secured after extensive engagement with the Tahltan Nation and regulatory authorities.

• Projected all-in sustaining costs (AISC) are US$538/oz in years 1-5, placing it at the bottom of the industry cost curve.

• At spot prices ($4,500/oz Au, $70/oz Ag), the project delivers an NPV (5%) of C$2.6 billion, IRR of 138%, and payback in less than 8 months.

• Updated 2026 project capex is US$659 million, with US$305 million incurred by end of 2025 and US$354 million remaining.
