Serbia’s mining project pipeline is expanding across gold, copper and boron, with projects at different stages ranging from greenfield exploration and resource definition to feasibility, construction preparation and expansion of producing operations. Strickland Metals’ Rogozna, DPM Metals’ Čoka Rakita, BHP-backed exploration in Timok, Zijin Mining’s Serbian copper operations, Boron One’s Piskanja, Middle Island Resources’ western Serbia portfolio and Rio Tinto’s Jadar project illustrate the increasingly diverse development landscape.
Capital requirements are becoming a central consideration as projects advance. Beyond the size of mineral resources, developers are assessing mine designs, processing technologies, recovery rates, infrastructure requirements and the conversion of exploration resources into reserves that can support financing and development.
Rogozna moves toward a defined mine development
At Strickland Metals’ Rogozna project in southern Serbia, development work is focused initially on the Gradina deposit. The company has outlined a conceptual operation capable of processing approximately 2.5 million tonnes of ore per year, with potential annual gold production of up to 150,000 ounces, or about 4.7 tonnes. The figure remains a development scenario rather than a production forecast.
Gradina contains an Inferred resource of approximately 1.8 million ounces of gold grading 2.8 grams per tonne, while the wider Rogozna mineral system contains around 9.25 million ounces of gold-equivalent resources. Strickland is targeting completion of a pre-feasibility study in 2027. The development approach could see Gradina serve as an initial production centre, while larger deposits such as Shanac are retained for potential later expansion.
This staged approach would allow the company to develop a smaller initial operation rather than immediately constructing a mine based on Rogozna’s largest deposit. The immediate technical focus is on converting sufficient resources into higher-confidence categories to support mine design, reserves and financing.
Čoka Rakita approaches construction and expands exploration
DPM Metals’ Čoka Rakita project in eastern Serbia is at a more advanced stage of development. The project has probable reserves of approximately 7.34 million tonnes grading 6.44 g/t gold. The current development plan includes an 850,000-tonne-per-year processing plant and average production of approximately 189,000 ounces of gold annually during the first five full years. Construction is targeted for 2027, subject to permitting and a final investment decision, while first concentrate is planned for the first half of 2029.
Exploration is also extending beyond the initial mine area. At nearby Dumitru Potok, drilling has produced copper-gold intersections including approximately 246 metres grading 1.36% copper-equivalent.
The broader Rakita Camp contains approximately 84.4 million tonnes averaging 0.97 g/t gold and 1.02% copper. This resource base provides the potential for a wider gold and copper mining complex centred on infrastructure initially developed for Čoka Rakita. Existing processing facilities, roads, electricity connections and mine services could become important components of future development because of their contribution to overall project costs.
BHP-backed exploration targets concealed Timok deposits
At the exploration end of Serbia’s mining pipeline, BHP is funding a major greenfield programme through its cooperation with Mundoro Capital. The combined exploration portfolios provide exposure to more than 800 square kilometres in and around the Timok copper-gold belt. The Central Timok project covers approximately 418 square kilometres and contains more than 20 exploration targets. Exploration is using induced-polarisation surveys, electromagnetic methods, magnetic data, passive seismic techniques and deeper drilling to search for concealed porphyry and epithermal systems.
The approach reflects the technical challenges of exploring mature districts where future discoveries may occur beneath cover or at greater depth, increasing exploration costs while potentially expanding the value of successful discoveries.
BHP’s involvement brings major-miner technical capability and long-duration exploration capital into a district already associated with the Bor complex and Čukaru Peki. No economic discovery has yet been defined by the current programmes, leaving the exploration investment focused on geological potential rather than near-term production.
Zijin expands Serbia’s established copper production base
Zijin Mining is pursuing a different development strategy through the expansion of its existing Serbian copper operations. The company produced close to 300,000 tonnes of mined copper in Serbia in 2025, while longer-term plans envisage combined capacity increasing towards 450,000 tonnes per year.
Achieving that scale requires investment beyond additional ore extraction. Expansion includes greater flotation capacity, underground haulage, shafts, conveyors, electrical systems, water recycling and waste-management infrastructure.
Development of the deeper Lower Zone at Čukaru Peki is particularly capital-intensive, requiring major underground infrastructure and additional processing capacity. The work therefore represents development beneath an existing operation rather than a straightforward extension of current mine workings. Higher copper output also creates requirements across the wider mining supply chain, including automation, power systems, ventilation, pumps, mills, flotation equipment, process control, environmental monitoring and maintenance.
Piskanja advances Serbia’s boron development pipeline
Boron One’s Piskanja project represents a smaller-scale critical-mineral development model focused on underground boron mining. The project’s economics depend significantly on processing efficiency and product quality. Recent test work produced commercial-grade colemanite concentrate from material designed to replicate future run-of-mine feed, including expected waste-rock dilution.
The test work is relevant to potential operating performance because results based exclusively on selected high-grade material can overstate expected performance under actual mining conditions. Boron One is also drilling across the wider Jarandol Basin to assess whether Piskanja forms part of a larger borate system. Additional resources could support the use of shared mining and processing infrastructure. Boron is used in specialty glass, ceramics, insulation, fertilisers and advanced industrial materials, placing the project within Serbia’s broader critical-minerals development pipeline rather than limiting the sector’s focus to lithium.
Western Serbia attracts new copper and gold exploration
Middle Island Resources is adding another early-stage exploration component to Serbia’s mining pipeline. The Australian company’s portfolio covers more than 600 square kilometres across Priboj, Bobija and Timok. Although the projects remain at an early stage, exploration has identified significant copper and gold anomalies.
At Jelaca near Priboj, a copper anomaly extends approximately 900 metres by 400 metres, with selected rock samples grading up to 3.21% copper. Gold targets are also being advanced at Zabrnjica, Beli Potok and Bobija. None of these targets has yet been defined as a mineral resource. The exploration nevertheless expands the geographic focus of Serbia’s modern mining activity, with Australian exploration capital applying systematic geochemical, geophysical and drilling programmes in western and southwestern districts.
Jadar remains under care and maintenance
Rio Tinto’s Jadar lithium-borates project represents a different stage of capital allocation. The project is geologically well defined and remains strategically important to European lithium supply, but Rio Tinto has placed Jadar into care and maintenance.
The company is maintaining the project’s assets and preserving the option to reactivate development while limiting near-term capital expenditure. The project therefore differs from early-stage exploration, where capital is being deployed to establish whether an economic deposit exists. At Jadar, the resource is already known, while the development decision depends on market, permitting and investment conditions and the substantially larger capital commitment required to advance the project.
Serbia’s mining pipeline now spans several distinct development stages. DPM Metals is approaching construction, Strickland Metals is progressing from discovery toward mine development, Zijin Mining is expanding an established copper operation, BHP and Middle Island Resources are conducting exploration for future deposits, Boron One is advancing a smaller critical-mineral project, and Rio Tinto is maintaining a large strategic resource without committing new development capital.
