Eldorado Gold Cuts Olympias Lead Output Forecast
Processing limits tied to an ongoing expansion project prompt lower 2026 lead and zinc production guidance for the Greek mine.
Updated on Nov. 6, 2026 in Economic Indicators
Eldorado Gold lowered its 2026 full-year lead production guidance for the Olympias polymetallic mine in Greece, and also revised zinc guidance downward. The changes followed the release of its third-quarter 2026 financial and operational results.
Why it matters
Olympias produces gold, silver, lead and zinc, so reduced throughput affects multiple metal outputs at once. The revisions reflect a temporary constraint tied to a 650,000-tonne-per-year expansion rather than a change in the deposit itself.
Eldorado Gold's company-reported guidance lowers the 2026 lead midpoint by about 24.2%, from 15,000-18,000 tonnes to 11,000-14,000 tonnes, and the zinc midpoint by about 2.9%. The extraction does not specify how long processing restrictions will persist after the fourth quarter.
The players
Eldorado Gold
Eldorado Gold is a Canadian gold mining company with operations in several countries, including Greece's Olympias mine.
The details
The restrictions on processing throughput at Olympias are linked to an ongoing 650,000-tonne-per-year expansion project and are expected to affect the fourth quarter of 2026. The company expects the expansion to reach full production in the first half of 2027.
Timeline
Fourth quarter 2026: Olympias processing throughput restrictions expected.
First half of 2027: Expansion expected to reach full production.
Market Landscape
Temporary throughput constraints during capacity expansions are a recurring pattern at polymetallic mines, where output often dips before higher volumes arrive. The Olympias guidance cuts fit this pattern, with the expansion's full output expected in the first half of 2027.
Investors tracking base metals may see lower lead and zinc supply from Olympias during the fourth quarter of 2026. Guidance changes of this kind can influence expectations for mining output and related commodity prices.
The takeaway
Temporary expansion constraints can lower near-term output without changing a mine's long-term capacity. Watching when throughput returns to normal will show whether the revised guidance holds.
What happens next
Olympias processing throughput restrictions are expected in the fourth quarter of 2026, with the expansion expected to reach full production in the first half of 2027.
