In southeastern Bulgaria, near the borders with Turkey and Greece, the Ada Tepe gold mine in Krumovgrad has become a showcase for how modern technology and strict environmental standards can align mining with community development. Operated by Canada’s Dundee Precious Metals, the mine is located within the Natura 2000 Protected Area — an unusual setting for industrial activity — but is widely recognized in Europe as one of the region’s most environmentally responsible mining projects.
Local officials say the mine has revitalized the Krumovgrad area, creating jobs, supporting small businesses, and financing local infrastructure. “At first we faced protests from green activists,” explained Mayor Sebihan Mehmed. “But we clarified the question: do we not want a mine at all, or do we want one with the most advanced technology? Instead of cyanide, which would have meant 95% ore recovery, the company uses flotation with 75%, reducing environmental risk.” The mine also applies parallel reclamation methods for tailings and provides real-time water quality data online from multiple monitoring points.
Beyond mining, Dundee has established a development fund for small businesses, offering a mix of grants and soft loans. More than 70 projects have been approved, including a local canning factory to process the region’s abundant peppers. Investments have also been directed toward healthcare, education, and municipal infrastructure.
The Ada Tepe mine is expected to close in 2026, after which Dundee plans to hand over the land to Krumovgrad for transformation into a tourist zone by 2032. Plans include camping facilities, eco-trails, sports grounds, and educational areas.
For Bulgaria’s neighbors, including North Macedonia, the project is an important case study. A Macedonian delegation of officials, engineers, and journalists recently visited the site to learn best practices for sustainable mining. “This mine is recognized in Europe as one of the most environmentally friendly,” said Filip Petrovski, Macedonia’s State Secretary for Mining. “We want to learn how responsible cooperation with local communities and clear regulations can build a sustainable sector.”
Debates over mining remain heated in Macedonia, particularly regarding cyanide use, which will soon be prohibited under new regulations. Activists in Strumica have long opposed concessions for gold mines in fertile farmland, citing environmental and health concerns.
The example of Ada Tepe suggests that with strong regulation, advanced technology, and community engagement, mining can deliver economic and social benefits while laying the groundwork for sustainable post-mining development.
