Eldorado Gold Corporation (TSX: ELD) (NYSE: EGO) is pleased to announce that first copper-gold concentrate has been produced at its wholly owned Skouries Project in northern Greece, marking a significant milestone in the transition of the project from construction to operations and a major step toward commercial production which is expected to be achieved in the fourth quarter of 2026.

First concentrate was produced on September 8 as part of the ongoing commissioning and ramp-up of the processing plant. This milestone follows the introduction of first ore to the crusher in July and reflects the successful commissioning of key process plant systems, including crushing, grinding, flotation and tailings thickening circuits. The ore stockpile currently exceeds 4.6 million tonnes above reserve grade, providing a strong foundation for ramp-up and underpinning more than seven months of processing throughput and concentrate production.

“This is a defining moment for Eldorado,” said George Burns, Chief Executive Officer. “First concentrate at Skouries represents the culmination of years of development, construction and partnership and marks the beginning of a new chapter for our Company. Skouries is not only a transformational asset for Eldorado, but also one of the most significant investments in Greece and one of Europe’s largest copper-gold projects. Together with McIlvenna Bay in Saskatchewan, Skouries is expected to transform Eldorado into a larger, more diversified precious metals and critical minerals producer with a stronger production base, meaningful copper and silver exposure and enhanced free cash flow generation. We are proud of what has been accomplished through our partnership with the Greek government and banks, local communities, our workforce and other stakeholders, and we look forward to creating long-term value and benefits for Greece and all stakeholders for decades to come.”

Key infrastructure commissioning has steadily progressed with crushing, grinding, flotation, tailings thickening, and concentrate thickening systems operating successfully. Temporary on-site power generation continues to support early operations and ramp-up until connection to the national power grid is achieved, which remains subject to final inspections, testing and installation of metering equipment by the Greek transmission authority and is expected in September 2026.
