Radiant Prospects Dimmed: Zijin Mining Suspends Copper-Cobalt Operations Amid Radiation Concerns

In a striking development within the mining industry, Zijin Mining Group Ltd.'s copper and cobalt operation in the Democratic Republic of Congo has ground to a halt. This suspension is amidst growing concerns about high levels of radiation detected in the cobalt extracted from its site. This alarming issue sparked immediate action, with the company ceasing activities at the La Compagnie Minière de Musonoie project, also known as COMMUS. Sources familiar with the unfolding situation disclosed that the mine stopped operating earlier this week, but requested anonymity due to the sensitivity of the information and lack of authorization to publicly discuss the matter.

A Closer Look at the COMMUS Shutdown

Government representatives have converged on COMMUS to closely monitor the cessation of production. Their oversight extends to rigorous testing procedures for cobalt shipments, which have been promptly halted and sent back subsequent to their initial export. The presence of uranium deposits in Congo's southeastern Katanga region can sometimes lead to contamination, a phenomenon that has unfortunately occurred in this instance.

Mining Disruption Echoes Through the Global Market

This suspension adds to a series of supply chain disruptions for the critical industrial metals. With the sudden closure of the Cobre Panama mine, owned by First Quantum Minerals Ltd., the copper market was already thrown into a state of flux. Joining the fray of contributing issues, Anglo American Plc has scaled back its production forecasts, while Codelco, in a historic downturn, has witnessed its output dwindle to levels not seen in over a quarter of a century. These incidents have coalesced, resulting in a palpable strain on the worldwide availability of copper.

Impact on Copper and Cobalt Production Figures

The COMMUS mine has been a notable force in the global copper and cobalt sectors. In the previous year, the project successfully yielded around 129,000 tons of copper, which amounted to approximately 4.2% of the total global yield. This firmly established it as an important contributor to the world, which stands as the second-largest producer of the metal. The mine's cobalt production was equally significant, with an output of 2,200 tons over the same period.

Ownership and Operational Influence in Congo

China's Zijin boasts a dominant 72% ownership stake in COMMUS, situating it at the heart of the mining-centric Kolwezi region in Lualaba province. Meanwhile, the remaining 28% is controlled by the state-run enterprise Gecamines. This is not Zijin's only venture within the area; the company also holds a stake in Congo's largest copper project, the Kamoa-Kakula, which is run by Ivanhoe Mines Ltd.

Silence from Stakeholders

The implicated parties, including Zijin and Congo's Minister of Mines Antoinette N'Samba Kalambayi, as well as the Mining Minister of Lualaba, Jacques Kaumba, have refrained from commenting on the situation. Equally tight-lipped is Gecamines, which has chosen to withhold any statements at this juncture. Assistance in reporting has been provided by Alfred Cang and Winnie Zhu, who have endeavored to bring clarity to the details surrounding the closure.

A Global Manufacturing Outlook Entwined with Copper Prices

The reverberations of the recent mine suspensions are finding their way to the global markets in a direct and impactful way. Only weeks ago, visions of positivity shimmered as copper prices soared on the back of an optimistic global manufacturing forecast and industry disruptions.

As a visual testament to this commodity's significance, the powerful imagery of molten copper being expertly poured into molds at Zijin's Serbia Copper plant in Bor, Serbia, served as a reminder of the vibrant and dynamic nature of the metal's industry.

Further Industry Ramifications

The incident extends beyond the borders of the Democratic Republic of Congo and affects various stakeholders across the international landscape. With copper being an essential component for several key industries, including electronics, construction, and renewable energy, any disturbances in its supply can have significant economic implications globally.

Moreover, cobalt, whose mining typically accompanies copper extraction due to their often intertwined deposits, is a critical material in the manufacturing of batteries, especially those found in electric vehicles (EVs). With the burgeoning EV market continually expanding, a stable supply of cobalt is imperative to maintain the anticipated growth trajectory within this sector.

Contamination and Regulation Challenges

The underlying issue of uranium contamination serves as a stark reminder of the extraordinary challenges faced in mining operations, particularly in regions with rich natural resource deposits like the Katanga region in the DRC. The industry must grapple with regulatory hurdles, environmental concerns, and matters of worker safety, all while trying to maintain a seamless supply chain. Continued vigilance and stringent quality control measures are critical to avoid such setbacks as experienced by the Zijin Mining Group.

Zambia's Power Struggles and Copper Mines

In a related development that emphasizes the fragility of the mineral extraction sector, Zambian copper mines have recently been put on alert due to imminent threats of power cuts by the state utility.

Economic Implications

The cessation of operations at key mining sites such as COMMUS exacerbates the pressures on an already tight market. This has potential ripple effects on the global economy, as the price of copper is often seen as a health indicator for manufacturing and construction due to its widespread use in both sectors. Investors and analysts alike keep a keen eye on copper prices as a barometer for economic growth.

Looking Ahead

As the industry navigates through these turbulent times, the future of copper and cobalt mining in the Democratic Republic of Congo hangs in the balance. Stakeholders eagerly await further developments, hoping for a swift resolution to the radiation issue and a resumption of COMMUS operations. The quick response to this crisis will be a telling sign of the resilience and adaptability of the global mining sector.

Environmental and Ethical Considerations

In the wake of such events, the topic of ethical mining practices comes to the forefront. Environmental protection alongside the community and worker welfare are pivotal in conducting sustainable and responsible mining activities. The mining industry is increasingly held to higher standards of accountability, as consumers and regulators demand transparency in sourcing and an unwavering commitment to ecological stewardship.

The Importance of Cobalt and Copper

Cobalt, while crucial for the emerging technologies enabling the green economy, particularly in its role within lithium-ion batteries, illustrates the challenges of maintaining ethical supply chains. Similarly, copper, with its electrical conductivity and heat resistance, remains a staple for infrastructure and technological innovation. Together, these metals embody the essence of modernity's march toward a renewable future.

Securing a Sustainable Metal Supply

The recent event at COMMUS underscores the need for strategic planning and investment in technologies to guard against supply disruption. Innovation in mining practices, exploration for new reserves, and the pursuit of recycling and alternative materials are all part of the broader conversation as industries aim to secure stable and sustainable supplies of essential metals like copper and cobalt.


The suspension of operations at Zijin Mining Group's mine in the DRC is an acute reminder of the interconnected challenges facing the global mining industry. These issues span health and safety concerns, economic pressures, and environmental responsibilities. As the situation unfolds, the global community's response will not only mold the future of this particular mine but also set precedents for how the industry might tackle similar challenges that could emerge in the future.
