Dundee Precious Metals (DPM) has announced a landmark discovery at its Brevene South Porphyry (BSP) target in Bulgaria, intersecting a massive 713-meter interval of high-grade gold and copper mineralization. The discovery, located just one kilometer from the company’s flagship Chelopech underground mine, represents one of the most significant porphyry intercepts reported in Europe in recent years and potentially signals a major expansion of DPM’s resource base in the Tethyan Belt.
The standout drill hole, EX_BRESPO_03, returned 713 meters grading 1.31 g/t gold and 1.16% copper, starting from a depth of 1,172 meters. Within this broad intercept, the company identified a higher-grade core of 398 meters grading 1.48 g/t gold and 1.45% copper. According to DPM, the hole was still in progress at the time of the initial data release, suggesting the potential for further depth extension of the mineralized system.
A Tier-One Discovery Near Existing Infrastructure
The BSP discovery is situated within the southeastern portion of the Brevene exploration license, which is contiguous with the Chelopech mine’s reserve footprint. For investors and operators, the proximity to Chelopech: a high-margin, technologically advanced underground operation: is a critical factor. The ability to leverage existing processing facilities, tailings management, and a skilled local workforce could significantly lower the capital intensity of any future development at Brevene South.
“This is a game-changer for the district,” noted a European mining analyst following the release. “To hit nearly three-quarters of a kilometer of mineralization at these grades, especially within walking distance of an active mill, is the kind of exploration success that rarely happens in mature jurisdictions.”
The discovery comes at a time when the copper price forecast for 2026 remains robust, driven by the ongoing energy transition and the European Union’s push for domestic critical mineral supply security. With copper grades exceeding 1% over such a large interval, Brevene South stands out as a high-value asset in a region traditionally known for lower-grade porphyry deposits.
Technical Analysis of the Brevene South Intercept
The BSP target was identified through a combination of historical data re-interpretation and deep-penetration geophysical surveys. The mineralization is characterized by a classic porphyry style, with gold and copper associated with quartz-sulfide veining and dissemination within an altered volcanic and intrusive complex.
The scale of the intercept suggests a robust hydrothermal system. In the world of porphyry exploration, the “1% copper equivalent” mark is often considered the threshold for a high-tier discovery. DPM’s results at Brevene South significantly exceed this, particularly given the strong gold co-product, which provides a natural hedge against base metal volatility and supports lower AISC trends for gold-heavy assets.
| Drill Hole | From (m) | To (m) | Interval (m) | Gold (g/t) | Copper (%) |
|---|---|---|---|---|---|
| EX_BRESPO_03 | 1,172 | 1,885 | 713 | 1.31 | 1.16 |
| including | 1,487 | 1,885 | 398 | 1.48 | 1.45 |
| EX_BRES_555_02 | 1,250 | 1,345 | 95 | 0.43 | 0.48 |
| EX_BRES_555_02A | 1,357 | 1,394 | 37 | 0.53 | 0.63 |

The depth of the discovery: beginning at over 1,100 meters: indicates that any future mining would likely involve high-capacity underground methods, such as block caving or long-hole stoping, techniques that DPM is already proficient with at its Bulgarian operations.
Strategic Implications for Dundee Precious Metals
For DPM, the BSP discovery validates a multi-year strategy of aggressive brownfield exploration. While the company has been active in searching for new deposits across the Tethyan Belt, finding a potential “Chelopech 2.0” so close to home is the ideal outcome for its 2026 growth pipeline.
This discovery also strengthens DPM’s position during a period of intense mining M&A momentum. Large-scale gold-copper porphyries are the primary targets for major diversified miners looking to secure long-life assets. By proving up a significant system in a stable European jurisdiction, DPM increases its strategic value significantly.
Permitting and Next Steps in Bulgaria
Bulgaria has established itself as a mining-friendly jurisdiction within the EU, with a clear regulatory framework for exploration and development. DPM has a long history of successful social and environmental performance in the country, which should facilitate the transition from exploration to permitting.
The company has indicated that the next phase of work will involve:
- Aggressive Delineation Drilling: Expanding the drill program to define the lateral and vertical extent of the BSP system.
- Commercial Discovery Application: Submitting the necessary documentation to the Bulgarian Ministry of Energy to secure a Commercial Discovery Certificate.
- Mining Concession Application: Initiating the formal process for a mining concession, which will include comprehensive Environmental and Social Impact Assessments (ESIA).
Given the depth of the mineralization, technical studies will likely focus on the feasibility of an underground bulk-mining scenario that minimizes surface footprint: a key consideration for modern ESG-focused mining operations.
Conclusion: A New Chapter for Bulgarian Mining
The 713-meter intercept at Brevene South is more than just a high-grade hit; it is a signal that the Tethyan Belt in Eastern Europe still holds significant, untapped potential for world-class discoveries. As DPM continues to drill out the deposit, the industry will be watching closely to see if this evolves into a multi-decade cornerstone asset.
For the broader market, this discovery underscores the value of deep exploration near existing infrastructure. In an era where new discoveries are increasingly difficult to find, DPM’s success in Bulgaria provides a blueprint for organic growth through technical excellence.
