Mineral Reserves Update

The Company's Proven and Probable gold Mineral Reserves totalled 12.5 million ounces as of September 30, 2025, representing an increase of approximately 5% compared to the previous MRMR statement dated September 30, 2024. The complete MRMR table and notes can be found at the end of this release.

Mineral Resources Update

Eldorado's Measured and Indicated Mineral Resources ("M&I Mineral Resources") totalled 17.4 million ounces gold, as of September 30, 2025. The Company's M&I Mineral Resources decreased 5% compared to the previous MRMR statement. The decrease was primarily driven from depletion at Kisladag and Perama Hill as a result of reclassification of a portion of the oxides to Inferred Mineral Resources.

Eldorado's Inferred Mineral Resources totalled 8.2 million ounces as of September 30, 2025, reflecting a 21% increase from the previous MRMR statement. This increase was primarily driven by new Inferred Resources at Bonnefond located in the vicinity of the Lamaque Complex and at Perama Hill with the addition of resources in the sulfide zone.
