Greece’s new radical left-wing government revoked the approval required for Vancouver-based Eldorado Gold to complete construction of its Skouries processing plant, the company announced in early March.

The newly elected Syriza party government had previously stated its opposition to the mine, a gold-copper project operated by Eldorado’s subsidiary, Hellas Gold S.A.

“We are absolutely against it and we will examine our next moves on it,” Energy Minister Panagiotis Lafazanis told Reuters in January.

The revocation prompted a furious response from Eldorado. “The recent decision of the Ministry of Energy – if not reversed in a timely manner – may force Eldorado to reconsider its investment plans for Greece,” Eldorado CEO Paul Wright said in a statement.

Eldorado also asserted the ministry’s decision “has no legal basis” and said it will “act to protect the legal rights of the company, employees and stakeholders” if necessary.

The notice Hellas Gold received from Energy indicates the decision may be reversed once the ministry finishes an internal review process of Eldorado’s application to construct the processing plant, but has not been clear on the timing of the review.

Eldorado has spent more than US$450 million since 2012 on the construction and development of the Skouries and Olympias mines on the Chalkidiki Peninsula in northeastern Greece. It also operates a silver-lead-zinc mine in the area. The company announced plans earlier this year to invest another US$310 million in the development projects in 2015.

Eldorado said the approval revocation has so far caused “no material impact” to the construction schedule of Skouries.
