DPM Metals is expanding exploration in eastern Serbia after drilling extended copper-gold mineralisation around Dumitru Potok, increasing the scope of its exploration programme around the Čoka Rakita development. The company said drilling has extended the Dumitru Potok mineralised system 90 metres west and 100 metres southwest of the existing resource, while additional mineralisation was identified about 300 metres north.
Recent drilling included 50 metres grading 3.68% copper equivalent, including 21 metres at 5.44%, as well as a separate 246-metre intersection grading 1.36% copper equivalent.
2026 Drilling Programme Expanded
DPM has increased its 2026 drilling programme to 32,000–35,000 metres, adding 12,000–15,000 metres to its previous plan. The company expects to have up to 15 drilling rigs operating across the licence by the end of 2026, compared with about 10 currently. An updated Dumitru Potok mineral-resource estimate is scheduled for the first quarter of 2027, followed by a preliminary economic assessment by the end of 2027. The expanded programme comes as DPM’s Serbian development strategy increasingly considers the potential of a wider copper-gold system surrounding the Čoka Rakita project rather than the economics of a standalone deposit.
Potential for Shared Mining Infrastructure
Čoka Rakita is already advancing toward mine development, with construction previously targeted to start in 2027. Further expansion at Dumitru Potok and neighbouring exploration targets could allow DPM to evaluate whether multiple deposits could share processing facilities, roads, power, water and other infrastructure.
A larger resource base could support infrastructure investment across a longer operating period and potentially support larger processing facilities or staged capacity expansion. The latest drilling, however, does not establish that such a district-scale development is commercially viable. Exploration intersections must first be converted into mineral resources, which would then need to demonstrate viable mining and processing economics.
Resource and Economic Studies Become Key Milestones
The 2027 resource update and economic study are expected to provide more significant development indicators than individual exploration results. Grade distribution will be important in determining whether higher-grade zones form mineable continuity rather than isolated intersections. Metallurgy, depth, geometry and infrastructure requirements will also influence whether additional resources can be integrated with Čoka Rakita. The larger drilling programme indicates that DPM is accelerating its assessment of the surrounding mineralisation and could evaluate several development scenarios before Čoka Rakita reaches production.
The outcome could affect future capital expenditure. A larger resource could support additional processing capacity, while district-scale infrastructure designed for future discoveries could require higher initial investment. DPM will therefore need to balance development timing with the possibility that additional discoveries could eventually exceed the capacity of infrastructure initially planned for the project.
Eastern Serbia’s Copper-Gold Development Potential
The copper component is significant within Serbia’s mining sector, which already includes the Bor mining complex and Čukaru Peki. Copper is also increasingly important to European industrial policy because of its role in grid expansion, electrification and renewable-energy deployment.
A commercially viable additional copper-gold operation could further strengthen eastern Serbia’s role in Europe’s mineral supply chain. The Rakita exploration area remains at an earlier stage of development. For now, the key change is the continued extension of mineralisation beyond the currently defined resource and DPM’s decision to allocate additional drilling capacity to the Serbian licence.
