Canadian mining company DPM Metals has announced a significant new gold-copper discovery in Bulgaria, with drilling results indicating the potential emergence of a high-grade porphyry system near its flagship Chelopech mining operation. The discovery, located at the Brevene South Porphyry (BSP) target, lies just one kilometer from the existing reserve footprint of the Chelopech underground mine and could further enhance the long-term value of one of Europe’s most important precious and base metals districts.
The latest drilling campaign has delivered some of the strongest exploration results reported by the company in recent years, fueling optimism that the BSP target could evolve into a substantial new mineral resource.
Exceptional Drill Results Highlight High-Grade Potential
The standout intercept came from drill hole EX_BRESPO_03, which returned an impressive 713 metres grading 1.31 grams of gold per tonne and 1.16% copper, beginning at a depth of 1,172 metres.
Within this broader mineralized interval, the company identified an even higher-grade section measuring 398 metres grading 1.48 grams of gold per tonne and 1.45% copper from 1,487 metres depth. Importantly, drilling remains ongoing, suggesting the mineralized zone could extend even further. Mining analysts noted that the combination of strong grades and substantial thickness distinguishes the BSP target as a potentially significant porphyry discovery with considerable development potential.
Strategic Location Adds Significant Value
One of the most attractive aspects of the discovery is its proximity to existing mining infrastructure. The BSP target is situated within the southeastern portion of the Brevene exploration licence, directly adjacent to the Chelopech mining concession. This location could substantially reduce future development costs if the project advances toward production.
Existing infrastructure, operational expertise, and established permitting frameworks often provide major advantages for mineral projects located near active mines. For investors, this reduces many of the risks typically associated with developing entirely new mining operations.
Chelopech Remains a Cornerstone Asset
Located approximately 75 kilometers east of Sofia, the Chelopech Mine is widely recognized as one of Europe’s highest-grade operating gold-copper mines. The operation has been producing commercially for more than two decades and remains the company’s most valuable producing asset.
Recent exploration successes across the broader mining district have already demonstrated the area’s significant growth potential. Discoveries such as Wedge Zone Deep have highlighted opportunities for resource expansion both within and beyond the existing mine footprint. The latest BSP discovery further strengthens the district’s reputation as one of the most prospective mining regions in Southeastern Europe.
Large Hydrothermal System Suggests Expansion Potential
According to DPM, the newly identified mineralized zone sits within a large hydrothermal alteration system measuring more than 1,000 metres by 1,500 metres. The company reports that the system remains open in multiple directions, creating opportunities for future expansion as exploration continues.
Geological observations indicate strong continuity of mineralization across the target area, a key factor in determining whether future drilling can support the definition of a formal mineral resource. The scale of the hydrothermal system has encouraged the company to significantly expand its exploration efforts throughout the property.
Aggressive Drilling Program Underway
To accelerate exploration, DPM has deployed five high-capacity drill rigs at the BSP target. The company plans to complete up to 15,000 additional metres of drilling before the end of the year as it seeks to better understand the geometry, continuity, and overall size of the mineralized system. The primary objective is to determine whether the discovery can support a resource estimate that may eventually justify commercial development.
Several additional drill holes have already returned encouraging results.
Among them:
- EX_BRES_555_02 intersected 95 metres grading 0.43 g/t gold and 0.48% copper
- EX_BRES_555_02A intersected 37 metres grading 0.53 g/t gold and 0.63% copper
These intercepts further support the growing geological model emerging across the BSP target area.
Fourth Major Discovery in Three Years
The Brevene South Porphyry discovery marks the company’s fourth significant exploration success since 2023.
Previous discoveries include:
- Čoka Rakita
- Dumitru Potok
- Wedge Zone
This consistent track record of exploration success demonstrates the effectiveness of DPM’s regional exploration strategy and reinforces the potential of its portfolio across Southeastern Europe. The latest discovery is being viewed as one of the most important developments in the company’s recent history due to its scale, grade, and proximity to existing operations.
Path Toward Commercial Development
DPM plans to continue exploration work through September before seeking a Commercial Discovery Certificate under Bulgaria’s mining regulations.
Following certification, the company intends to pursue:
- Mining concession approvals
- Environmental permitting
- Further technical evaluations
- Development planning
Advancing the project through Bulgaria’s regulatory framework will be a critical step toward determining the economic viability of future mining operations at BSP.
Strong Resource Base Supports Long-Term Production
The discovery arrives at a time when the Chelopech operation continues to demonstrate substantial long-term value. Earlier this year, the mine’s operating life was extended by four years, pushing production plans through 2036.
Current measured and indicated resources at Chelopech total approximately:
- 15.3 million tonnes
- 2.18 g/t gold
- 9.19 g/t silver
- 0.64% copper
These resources contain an estimated:
- 1.07 million ounces of gold
- 4.52 million ounces of silver
- 216 million pounds of copper
Inferred resources add:
- 9.1 million tonnes
- 573,000 ounces of gold
- 2.74 million ounces of silver
- 114 million pounds of copper
The combination of existing resources and new exploration discoveries positions the district for continued growth.
Gold and Copper Outlook Remains Strong
DPM expects Chelopech to produce between 150,000 and 170,000 ounces of gold during the current year, alongside approximately 29 million to 34 million pounds of copper.
With global demand for both gold and copper expected to remain robust—driven by investment demand, electrification, renewable energy infrastructure, and industrial growth—the latest discovery could significantly strengthen the company’s long-term production profile.
As drilling progresses, investors and industry observers will be closely watching whether Brevene South Porphyry evolves into the next major mining development within one of Europe’s most productive mineral districts.
