Eldorado Gold Connects Skouries to the Greek Grid, 20 Days After First Concentrate

Twenty days ago the Skouries mine in northern Greece produced its first copper and gold concentrate. Eldorado Gold Corporation said at the time that the concentrate came out "as part of the ongoing commissioning and ramp-up of the processing plant", which is the company's way of saying that a plant making product is not yet a plant running a business.

On 28 September the company reported the next gate. Skouries "has been successfully energized following completion of the permanent connection to the Greek national power grid following final inspection, testing and approval by the Greek transmission authority", according to the release Eldorado issued that morning. Nothing else in the announcement is new.

Permanent power is a utility connection, not a production rate

Until a mine is energized it runs on temporary supply, usually diesel generation, which is expensive per kilowatt hour and rarely sized to hold a concentrator at full load for weeks at a time. A permanent grid connection removes that constraint. It is the piece of infrastructure that lets a mill run continuously rather than in campaigns, and it has to be inspected and accepted by the national transmission operator before power flows, which is why it arrives as a dated event rather than a gradual improvement.

That is the whole of what the 28 September release establishes. It reports no tonnes through the mill, no head grade, no recovery, no concentrate tonnage and no cost figure. It is not first production, which Eldorado reported on 8 September. It is not the completion of commissioning, which the company describes as ongoing in both releases.

Chief executive officer George Burns put it in those terms: "Site energization is an important step in advancing Skouries toward ramp up to steady-state operations." The same quote says the connection "supports the ongoing commissioning and ramp up of key systems across the site and provides the long-term power infrastructure required for the operation." Neither sentence claims a rate.

The schedule has not moved, and the test for meeting it is not published

Eldorado's second-quarter release of 30 July 2026 stated that "First production of the copper-gold concentrate is expected in Q3 2026 and commercial production is expected in Q4 2026." First concentrate then arrived on 8 September, inside the third quarter as forecast. Monday's release repeats the second half of that sentence, saying the project "progresses toward commercial production expected in the fourth quarter of 2026."

So the company has hit one of its own two dates and is still guiding to the other. The distinction matters, because commercial production is not an external certification. It is a threshold the operator declares, generally once a plant has held a defined share of design throughput and recovery over a defined period, and the point at which accounting stops capitalising costs and starts running them through the income statement. Eldorado has not published the throughput and recovery test it will apply at Skouries, or the length of the run it requires. Until it does, the fourth-quarter date is a company forecast rather than a measurable condition an outsider can check against.

Most of the money is already spent

The capital figures are the reason the schedule matters. As at 30 June 2026, Eldorado reported US$1.270 billion of cumulative Skouries project capital and US$201.3 million of cumulative accelerated operational capital, against an estimate of about US$260.0 million for the latter and about US$1.315 billion for total Skouries capital to commercial production. Subtracting the first figure from the last leaves roughly US$45 million of the project-capital estimate outstanding at the end of June, a calculation of ours rather than a number the company states. Skouries absorbed US$154.6 million of project capital in the second quarter alone.

The effect on group cash flow is visible and it is temporary by design. Eldorado reported negative free cash flow of US$334.1 million in the second quarter and negative US$463.2 million for the first half of 2026. Strip out Skouries and the McIlvenna Bay project and the second quarter was positive US$40.9 million. The company held cash and cash equivalents of US$554.6 million and total debt of US$1,749.9 million at 30 June 2026. Those balance-sheet figures are taken from Eldorado's own 30 July 2026 results release; the interim financial statements filed since were not available when this was written, so they are the company's reported numbers rather than statement-verified ones.

What Skouries is expected to return, once it is running, is an average of 140,000 ounces of gold and 67 million pounds of copper a year over its life, according to the 28 September 2026 release. The mine plan behind that rests on proven and probable reserves of 148.0 million tonnes grading 0.77 grams of gold per tonne and 0.50 per cent copper, containing 3.67 million ounces of gold and 741,000 tonnes of copper, as stated in Eldorado's reserve and resource summary effective 30 September 2025.

Two assumptions inside that estimate deserve attention. The first is a long-term gold price of US$1,700 an ounce, less than half the level gold traded at on 28 September 2026 on secondary market data. The second is the net smelter return cut-off grade, US$15 a tonne for the open pit and US$40 a tonne underground, which is the value of metal a tonne of rock must contain before it is worth processing at all. A reserve built at a conservative price is the version of the asset that survives a weaker market, and it also means the published ounce count is not the figure a mine plan run at today's price would produce.

Eldorado's own project page describes Skouries as about 97 per cent complete as at 30 June 2026, with an initial life of mine of 20 years.

Monday's decline belonged to the gold complex

The shares did not respond to the announcement in any way that can be separated from the sector. Secondary market data for the 28 September session, 15-minute delayed and not verified against exchange records, showed Eldorado at C$56.80, down 4.28 per cent, on 0.81 times its thirty-day average volume. Agnico Eagle Mines Limited fell 4.61 per cent the same session and Alamos Gold Inc. fell 4.32 per cent, neither having announced anything. Gold itself was down sharply on the day.

A company that reported a construction milestone therefore traded roughly in line with producers that reported nothing, on below-average volume. The milestone also drew no measurable discussion on Canadian retail investor boards that day. Both observations point the same way: the market treated energization as procedural.

Three currencies sit between the asset and the price

Eldorado's shares trade in Frankfurt under the symbol ELO1, with German securities identification number A2PA9H and ISIN CA2849025093, according to Börse Frankfurt's listing page read on 28 September 2026. They are the same common shares that trade in Toronto, so the euro quotation and the Canadian dollar quotation differ only by exchange rate and venue.

That matters here more than it usually does, because the ownership chain is unusually spread out. The asset is in Halkidiki, inside the euro area. The company reports in US dollars. The primary listing and the largest price discovery are in Canadian dollars in Toronto. An investor holding the German line is exposed to a Greek construction schedule through a US-dollar income statement and a Canadian share price, and none of those three currencies is the one the concentrate will be sold in at any given moment.

What is proven and what is still a forecast

Skouries now has grid power, ore, a first concentrate and about US$1.27 billion of sunk project capital. Those are facts with dates on them. The 20-year mine life, the 140,000 ounces and the 67 million pounds are a plan, and the fourth-quarter commercial production date is a company expectation that no published threshold currently pins down.

The single number that would change the picture is not another gate. It is a quarter of throughput and recovery at Skouries, disclosed with the same specificity as the capital. Eldorado's next quarterly report is the first document that could carry one.
