Skouries Powers Up as Eldorado Ties Mine to Greek Grid

Eldorado Gold Corporation said the Skouries copper-gold project in northern Greece has been energised after the permanent connection to the Greek national power grid was completed and approved by the country's transmission authority.

Eldorado Gold Corporation (EGO) has confirmed that its Skouries project in northern Greece is now drawing power from the Greek national grid. The company said the mine was successfully energised after the permanent grid connection was completed and passed final inspection, testing and approval by the Greek transmission authority.

In a statement carried by International Mining, the company described the milestone as "an important step in advancing Skouries toward ramp up to steady-state operations."

Why a grid connection is a gating item, not a formality

Energisation sounds procedural. It is not. Until a processing plant is connected to firm, permanent power, almost nothing downstream can be sequenced with confidence. Mills, flotation circuits, thickeners, tailings pumps, conveyors and control systems all need to be run up, tuned and commissioned under load — and doing that on temporary diesel generation is expensive, capacity-constrained and generally unsuitable for the sustained testing that commissioning requires.

A permanent transmission tie also changes the operating economics. Grid power is normally cheaper per unit than on-site generation, and for a grinding-and-flotation operation, electricity is one of the largest single line items in the cost stack. Locking in that connection is therefore both a schedule event and a cost event.

The other point worth drawing out is the regulatory one. The connection required sign-off from Greece's transmission authority following inspection and testing. That approval closes out a permitting-adjacent workstream that has, at other projects in Europe, proved capable of slipping by quarters. Eldorado has now cleared it.

What energisation does and does not tell investors

Energisation marks the transition from construction into commissioning and ramp-up. It does not by itself establish the date of first production, the rate at which throughput will climb toward nameplate, or the cost per ounce once the operation is steady. Those remain the numbers that will determine how Skouries is valued, and the company's own guidance is the only reliable source for them.

What the announcement does establish is direction of travel. Ramp-up is the next phase, and the company has framed the milestone explicitly in those terms. For a project that has been under construction and under public scrutiny in northern Greece for years, moving from "building" to "commissioning" is the change in posture that matters.

Investors watching this sort of transition typically track a short list of markers:

• First ore through the mill, and the date it is announced rather than guided.
• Throughput as a percentage of design capacity, disclosed quarter by quarter.
• Recovery rates for both the copper and gold streams, which tend to lag throughput during ramp-up.
• Any revision to remaining capital to complete, and whether it lands inside the prior range.
• The first period in which the operation is reported as contributing to consolidated production and cost metrics.

A copper-gold asset arriving into a two-metal story

Skouries is a copper-gold project, which gives it a different profile from a conventional bullion mine. A meaningful copper credit can pull reported all-in sustaining costs on the gold ounces down materially, because by-product revenue is netted against cost in the standard disclosure. That works in reverse too: weakness in copper pricing flows straight through to the gold cost line.

For Eldorado, that means the asset's contribution will be read against two commodity markets at once rather than one. It also means the mine's cash generation is less exposed to a single price path than a pure gold operation of comparable scale — a structural argument that producers with polymetallic assets have been making to generalist investors for some time.

The geographic dimension is not incidental either. A large copper source inside the European Union carries a supply-security premium in the current policy environment, where European and North American governments have been actively working to reduce dependence on concentrated non-domestic supply chains for industrial metals. A producing Skouries is a European copper unit, and that is a different thing from an equivalent tonne produced elsewhere.

The share price context

Eldorado Gold shares last traded at 38.49, down 1.05% on the day, against a previous close of 38.90. The stock moved in a range of 38.06 to 39.39 across the session, according to market data as of 20:00 GMT on 30 September 2026, when the market was closed.

That modest decline came on a mixed day for the broad market. The S&P 500 tracker (SPY) closed at $762.63, down 0.21%, and the Dow 30 tracker (DIA) finished at $508.55, off 0.84%, while the Nasdaq 100 tracker (QQQ) ended at $739.77, up 0.25%.

The muted reaction is consistent with how commissioning milestones usually trade. Energisation is a de-risking event rather than a revenue event: it removes a way the schedule could have gone wrong without adding an ounce or a pound of production. Equity markets tend to pay for the latter. The re-rating argument, if there is one, generally arrives when throughput and recovery numbers start appearing in quarterly disclosure and the market can test the project's assumptions against actual plant performance.

What to watch from here

The near-term checkpoints are commissioning of the process plant under grid power, the company's next operational update, and any change to the production and capital guidance already in the market. The longer-term question is how quickly Skouries reaches steady state and what it does to Eldorado's consolidated cost profile once the copper by-product credit is flowing.

For now, the mine has power. That is the step that had to come first.

Frequently asked questions

What did Eldorado Gold actually announce about Skouries?

Eldorado Gold Corporation announced that the Skouries mine in northern Greece has been successfully energised. This followed completion of the permanent connection to the Greek national power grid, which was subject to final inspection, testing and approval by the Greek transmission authority. The company called it an important step toward ramp-up to steady-state operations.

Why does energising a mine matter?

Permanent grid power allows a processing plant to be commissioned under sustained load rather than on temporary generation. Mills, flotation circuits, pumps and control systems can then be run up and tuned properly. Grid electricity is also normally cheaper per unit than on-site diesel generation, which matters because power is a major cost line at a grinding and flotation operation.

Does energisation mean Skouries is producing metal?

No. Energisation marks the transition from construction into commissioning and ramp-up, not the start of commercial production. First ore through the mill, throughput as a share of design capacity, and recovery rates are separate milestones that follow. Eldorado's own operational updates are the source for timing on those steps.

Where did EGO shares close?

Eldorado Gold shares last traded at 38.49, down 1.05% from a previous close of 38.90, with a session range of 38.06 to 39.39. That is the most recent close as of 20:00 GMT on 30 September 2026. The market was closed at the time of writing, so this is a last traded price rather than a live quote.

Why does the copper content of Skouries matter to a gold producer?

Skouries is a copper-gold project. Under standard mining disclosure, by-product revenue is netted against costs, so copper sales can reduce reported all-in sustaining costs on the gold ounces. That cuts both ways: weaker copper pricing feeds straight back into the gold cost line. It means the asset is read against two commodity markets rather than one.

What should investors watch next at Skouries?

The key markers are commissioning of the process plant under grid power, the date first ore goes through the mill, quarterly throughput as a percentage of design capacity, copper and gold recovery rates during ramp-up, any change to remaining capital to complete, and the first period in which Skouries contributes to consolidated production and cost figures.
