Name of the Project
Skouries gold/copper project.

Location
Halkidiki peninsula, northern Greece.

Project Owner/s
Hellas Gold, a subsidiary of midtier gold producer Eldorado Gold Corporation (95%), and Aktor (5%).

Project Description
The gold/copper porphyry deposit is planned to be mined using a combination of conventional openpit and underground mining techniques. The mineral process facilities will produce doré and a gold/copper concentrate.

The project has total proven and probable reserves of 157.67-million tonnes grading 0.74 g/t gold and 0.49% copper. 

Mineral resources have been estimated at 289.28-million tonnes grading 0.58 g/t gold and 0.43% copper, with inferred mineral resources of 170.14-million tonnes grading 0.31 g/t gold and 0.34% copper.

Gold production has been estimated at 140 000 oz/y. Average copper production is estimated at 67-million pounds.

Skouries has been designed as a two-phase operation.

Phase 1 comprises a combined openpit and underground mine operating over ten years.

Skouries will be a conventional truck-and-shovel operation. The mining sequence will consist of drilling, blasting and loading, as well as the hauling of ore and waste materials for processing and waste disposal.

Phase 1 total mill feed is eight-million tonnes a year consisting of a nominal 5.5-million tonnes a year from the openpit mine, combined with 2.5-million tonnes a year from the underground mine. 

At the start of the mine life, during the initial two-year underground mine ramp-up, the openpit feed rate is 6.4-million tonnes a year to maintain the eight-million-tonne-a-year mill feed. 

During Phase 1, about 6.5-million tonnes of oxide ore will be stockpiled, to be rehandled for mill feed during Phase 2. Phase 1 will be completed at the end of the openpit mine life in Year 10.

Phase 2 consists of underground mining for a further 13 years. Sublevel open stoping has been confirmed as the most appropriate underground mining method for the project.

Phase 2 mine production, from Year 11 to the end of the life-of-mine (LoM) of 23 years, will be provided from the underground mine. Phase 2 mine development begins in Year 4 to allow for a seamless ramp-up from the Phase 1 production of 2.4-million tonnes a year. During the first three years of Phase 2, the mill feed rate of eight-million tonnes a year will be maintained by reclaiming oxide ore stockpiled during Phase 1 at 1.6-million tonnes a year. 

From Year 14, Phase 2 mill feed will be maintained at an average of 6.2-million tonnes a year, solely from underground mine production.

The materials handling strategy for Phase 1 is based on truck haulage of run-of-mine ore directly to the surface from the loading bays using the dual ramp system.

Phase 2 materials handling will involve the shaft hoisting of ore to the surface. Shaft hoisting is critical to allow for ramp-up to full production of 6.4-million tonnes a year from the Phase 1 production of 2.5-million tonnes a year. 

To hoist the material by shaft, underground crushing will be implemented. The design of the Skouries mine includes provision for remote mining technology, which has an impact on the cycle times of stopes and the productivity of equipment. This technology includes the teleremote operation of mechanised equipment by an operator located on surface or in a remote area of the underground mine.

Potential Job Creation
Labour availability remains a key risk to the project, with Eldorado targeting a workforce of about 1 300 at peak construction. As of late January 2025, about 1 150 workers were on site. Eldorado continues to integrate various skills sets required for critical construction activities, including concrete, mechanical, electrical and control systems work.

Net Present Value/Internal Rate of Return
The project has an after-tax estimated internal rate of return of 19%, with a payback of four years.

Capital Expenditure
The project carries a revised capital cost estimate of $1.06-billion and remains fully funded, supported by €680.4-million in commercial and recovery and resilience facility funding.
Cumulative Phase 2 capital investment reached $980-million by the end of December 2025.

Planned Start/End Date
Production is expected in the first quarter of 2026, with commercial production expected by midyear.

Latest Developments
Eldorado Gold has initiated its first dividend programme, citing its strong financial position and growing confidence in the delivery of its Skouries copper/gold development.
The company’s confidence in launching the dividend programme is underpinned by progress at the project, which is approaching first concentrate production. It is expected to produce first concentrate towards the end of the first quarter of 2026, with commercial production targeted for midyear.

Overall project progress reached 90%, including the first construction phase, with 78% reached for Phase 2 as at December 31, 2025.

Mechanical completion has been achieved for all six tailings filters while openpit and underground mining activities are advancing ahead of schedule, with significant ore stockpiles established for plant startup.

Processing and maintenance teams are fully staffed and engaged in training and precommissioning activities, while concentrate offtake terms have been agreed with leading trading firms.

Eldorado also expects to benefit from improved offtake terms, with agreements expected to cover about 80% of concentrate production over two- to three-year periods.
