Urgent inquiry raised over planned gold mining near Greek–Bulgarian border

Greece’s opposition group Independent United Initiative has submitted an urgent inquiry to regional authorities, raising alarm over a planned gold mining project in Rozino, Bulgaria, near the Greek–Bulgarian border.

The inquiry, addressed to the President of the Regional Council and the Regional Governor of Eastern Macedonia and Thrace, warns of serious cross-border environmental risks, particularly for the Meriç region in northern Greece.

Concerns Over Environmental Impact
According to the group, licensing procedures for the project in Bulgaria are advancing rapidly, with public consultations scheduled for April 27–28, 2026, in affected areas including Rozino and Ivaylovgrad.

The opposition group highlighted potential threats to the Erythropotamos River basin, a critical irrigation resource for agricultural land in northern Meriç.

Citing scientific data, the statement warned of high concentrations of toxic substances such as arsenic and mercury, raising concerns over long-term water contamination, damage to the groundwater system, and risks to agricultural production.

Among the key claims:

• For every 1.28 grams of gold extracted, approximately 125 grams of arsenic per ton of ore could be released into the environment.
• Planned waste facilities may be constructed over the Yuren Dere stream, potentially directing contaminated water toward Greece during rainfall.
• The open-pit mine, expected to reach a depth of 140 meters, could deplete groundwater resources and threaten local drinking water supplies.

Questions Over Environmental Study

The group also questioned the credibility of the Environmental Impact Assessment (EIA), alleging inaccuracies and omissions, including the failure to adequately disclose the presence of hazardous substances in cross-border documentation.

It further claimed that incorrect hydrological data had been used, potentially undermining the reliability of the study.

Calls for Immediate Action
The Independent United Initiative called on regional authorities to:

• Publicly disclose the EIA submitted for consultation
• Send official representatives to the upcoming public hearings in Bulgaria
• Activate international procedures under the Espoo Convention, which governs transboundary environmental impacts
• Coordinate with local municipalities and seek intervention from European institutions
• The group also proposed a joint appeal to the European Commission, citing potential violations related to water protection and the Natura 2000 framework.

Regional Concerns Intensify
The statement concluded with a strong warning that the project could have lasting consequences for the region’s environment and agricultural economy, particularly if contamination affects irrigation systems and crop safety.

The issue is expected to escalate as public consultations approach, with local authorities and stakeholders under increasing pressure to respond.
