Eldorado Gold produces first copper-gold concentrate at Skouries

Commercial Production Expected in Q4 2026

VANCOUVER, British Columbia, Sept. 08, 2026 (GLOBE NEWSWIRE) -- Eldorado Gold Corporation (TSX: ELD, NYSE: EGO) (“Eldorado” or the “Company”) 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.

Skouries is expected to produce on average 140,000 ounces of gold and 67 million pounds of copper annually over the life of mine.

With respect to the Skouries Project, these risks, uncertainties and other factors may cause further delays in the completion of the construction and commissioning at the Skouries Project which in turn may cause delays in the commencement of production and further increases to the costs of the Skouries Project. The specific risks, uncertainties and other factors include, among others: our ability to efficiently manage the transitions from construction to commissioning to operations (including EPCM performance and owner team turn over); our ability to increase productivity by, among other things, adding or modifying labour shifts; rising labour costs or costs of key inputs such as materials, power and fuel; risks related to any unanticipated critical equipment defects or failures during the commissioning and ramp-up of operations; risks related to third-party contractors, including reduced control over aspects of the Company's operations, and/or the ability of contractors to perform at required levels and according to baseline schedules, costs of any engineering rework and any commercial disputes that may arise from a contractor’s failure to meet these requirements; the ability of key suppliers to meet key contractual commitments in terms of schedules, amount of product delivered, cost, or quality and the impact of any vendor data errors; impacts to overhead costs related to the schedule; our ability to construct key infrastructure within the required timelines, including the process plant, filter plant, substation, waste management facilities, embankments, tailings conveyors, and water management infrastructure; the timely receipt of necessary permits and authorizations and our ability to comply with the terms of existing and future permits and authorizations; differences between projected and actual degree of pre-strip required in the open pit; variability in metallurgical recoveries and concentrate quality due to factors such as extent and intensity of oxidation or presence of transition minerals; presence of additional structural features impacting hydrological and geotechnical considerations; variability in minerals or presence of substances that may have an impact on filtered tails performance and resulting bulk density of stockpiles or filtered tails; distribution of sulfides that may dilute concentrate and change the characteristics of tailings; unexpected disruptions to operations including due to protests, non-routine regulatory inspections, road conditions, on site or labour unrest; unexpected inclement weather and climate events, including wildfires, short and long duration rainfall and floods and other extreme weather events and our site's ability to respond to those events; our ability to meet pre-commercial producing mining or underground development targets; unexpected results from underground stopes; new archaeological discoveries requiring the completion of a regulatory process; changes in support from local communities; and our ability to meet the expectations of communities, governments, and stakeholders related to the Skouries Project. Our project capital and accelerated operational capital costs at Skouries are incurred primarily in Euros but are reported in US dollars and are therefore sensitive to fluctuations in the EUR/USD exchange rate.
