Zijin Mining’s Serbian operations are producing copper and gold at scale, while Rio Tinto’s Jadar lithium project remains in care and maintenance, illustrating two sharply different investment paths through Serbia’s mining system. The companies entered the country under different ownership, permitting and community circumstances, with contrasting results for production and project development.
- Different development models shaped the projects
- Zijin’s production has brought measurable economic activity
- Jadar retains strategic importance without a settled development timetable
- Project legitimacy remains central to both investment models
- Serbia faces different governance requirements for both projects
Zijin entered Serbia in 2018 through the recapitalisation of the distressed RTB Bor copper complex, taking a 63% stake while the Serbian state retained 37%. The transaction brought the Chinese company into an existing industrial system comprising operating mines, a smelter, employees, environmental liabilities and communities whose economies were already linked to mining. The arrangement combined industrial restructuring, state participation and a strategic partnership. Expansion could therefore be presented within an existing national mining and employment framework rather than as the introduction of an entirely new extraction project.
Different development models shaped the projects
Rio Tinto approached Serbia through the development of Jadar, a greenfield lithium project based on a newly identified lithium-bearing mineral deposit in an agricultural area without an established mining compact comparable to Bor. The proposed project required the simultaneous development of infrastructure, regulatory approvals and community acceptance. Rio Tinto’s studies, disclosures and engagement activities could document the project, but they did not resolve opposition among residents concerned about the government approval process and potential long-term environmental effects.
The difference between the projects extends beyond the nationalities of their investors. Brownfield versus greenfield development, state co-ownership versus arm’s-length permitting, an established mining community versus contested agricultural land, and immediate production versus a future strategic project shaped the two outcomes. Zijin’s structure aligned government interests with employment and industrial output, supporting a faster transition into production. Jadar remained politically reversible because its permitting process depended on broader public acceptance that remained contested.
Zijin’s production has brought measurable economic activity
Zijin’s two Serbian operations reported combined 2025 production of 296,000 tonnes of copper and 9.1 tonnes of gold, placing the group among Europe’s largest copper producers. The company has also outlined a further $3.8 billion investment ambition focused on the Čukaru Peki Lower Zone. Unlike a stranded development project, the Serbian operations generate measurable production, exports, wages, tax revenues and investment. The same operating footprint, however, has also brought continuing environmental and social issues.
Residents around Krivelj have challenged aspects of mine expansion, relocation and pollution. Zijin has said that it inherited serious environmental problems and has invested more than $100 million in environmental improvements. In June 2026, the US Customs and Border Protection issued a withhold-release order covering products of Serbia Zijin Copper, citing indicators of forced labour. The measure is an administrative trade-enforcement action based on allegations rather than a Serbian criminal judgment. It also should not automatically be applied to the separately named Serbia Zijin Mining entity.
The action nevertheless places labour governance directly within the company’s market-access exposure. Production can continue while products, customers, insurers or financiers face additional scrutiny or restrictions.
Jadar retains strategic importance without a settled development timetable
The Jadar project remains relevant to European battery supply and was recognised by the European Commission in 2025 as a strategic project under the Critical Raw Materials Act framework for third countries. That designation strengthens the project’s strategic significance but does not itself constitute a Serbian construction permit, establish the validity of every environmental assessment or secure acceptance among affected communities.
Following years of protests, legal reversals and changes in political support, Rio Tinto currently describes Jadar as being in care and maintenance while continuing engagement. The company has retained the project option while limiting the commitment of full construction capital. The resulting position contrasts with Bor. Rio Tinto has incurred substantial expenditure on geology, project design and processing work, but Jadar has not entered production and has no settled development timetable.
Project legitimacy remains central to both investment models
Rio Tinto’s approach generated extensive corporate documentation and international visibility, but the volume of technical and procedural work did not resolve questions over the credibility of the decision-making process.
The Serbian state initially advanced elements of Jadar, subsequently cancelled them and later revived aspects of the project. That sequence demonstrated to opponents that political pressure could influence the project’s trajectory. European backing also strengthened concerns that strategic mineral demand could take precedence over local preferences. A technically developed mining project can therefore remain commercially unresolved when stakeholders dispute the legitimacy of the institutions responsible for approving it.
Serbia faces different governance requirements for both projects
The contrasting cases point to the need for a mining framework that applies consistently to both brownfield and greenfield developments rather than relying on different standards for different investors.
Concession terms, environmental baselines, water models, resettlement arrangements, labour conditions, beneficial ownership, state aid and community payments should be disclosed in comparable formats. Environmental monitoring would require independent laboratories and enforceable intervention thresholds, while municipalities would need predictable revenues and an effective mechanism for challenging non-compliance. For Zijin, the focus is on demonstrating that continued production growth can operate alongside verified labour standards, environmental remediation and fair relocation, while maintaining access to US and EU markets.
For Rio Tinto, the central requirement is a credible development sequence in which environmental assessment, local participation and government decisions remain stable despite political changes. The company would also need to retain the option of leaving Jadar undeveloped if that process cannot be established. Zijin currently has the stronger financial position in Serbia because its assets are producing at scale. Rio Tinto retains an option on Jadar but does not have a producing mine or a settled construction timetable.
