Recently, the situation in the Democratic Republic of the Congo (DRC) has escalated again, adding further uncertainty to the market supply of tantalum ore. Upon the release of this news, bullish sentiment among industry insiders has reignited. Can the CIF price of Chinese tantalum ore (Ta2O5≥30%) sustain the upward trend seen at the start of the year and break through the "100$ mark" in one fell swoop?

News Background

On November 16th, the DRC's Ministry of Mines announced that it had extended by six months the ban on mineral trade at 38 small-scale mines in North Kivu and South Kivu provinces affected by conflicts. The ban prohibits the mining and export of minerals from these mining areas, and the ministry stated that these sites may face independent audits by the Ministry of Mines or international bodies including the United Nations (UN) and the Organisation for Economic Co-operation and Development (OECD).

First implemented in February this year, the ban will remain in effect due to evidence that illegal supplies from these mines are funding armed groups in the eastern region. These mines produce tantalum-niobium ore, cassiterite, and wolframite (raw materials for tin, tantalum, and tungsten), and the extension will increase compliance pressures on the global supply chains of tin, tantalum, and tungsten. The Rwanda-supported M23 rebels and other armed groups have occupied mineral-rich areas in eastern DRC.

On November 23rd, the Chinese Ministry of Foreign Affairs and the Chinese Embassy in the DRC issued an urgent security alert, requiring Chinese citizens and enterprises remaining in high-risk areas of eastern DRC to evacuate immediately. This comes as armed conflicts in the region occur frequently, and incidents of attacks and kidnappings targeting Chinese citizens have surged.

Market Outlook Analysis

As core strategic minerals for the semiconductor, new energy, and other sectors, tantalum-niobium ore supply chains have seen significantly heightened instability globally due to the M23 armed group's control over relevant mining areas in the DRC. The scramble for mineral interests is the core of the conflict between the M23 armed group, the DRC government, and neighboring Rwanda, and this key divergence is further exacerbating the security situation on the ground. Meanwhile, the DRC accounts for 43% of global tantalum ore supply, and the border area between North Kivu and South Kivu provinces controlled by the M23 is precisely the core enrichment zone for coltan (columbite-tantalite). Among these, the Rubaya Tantalum Mine, one of the largest tantalum mines in the DRC, contributes 15%-20% of global coltan production. As a result, the ongoing conflict in the DRC has dealt a severe blow to the stability of global tantalum ore supplies. According to local tantalum ore miners, the current transportation of minerals out of the DRC faces significant obstacles, and relevant parties are still negotiating transportation arrangements.

Notably, data released by the General Administration of Customs shows that currently, 9% of China's total tantalum ore imports come from the DRC, meaning the direct impact is relatively limited. While some DRC tantalum ore is smuggled to Nigeria before entering China, the specific proportion of such sources remains unclear. Additionally, considering that China's import dependence on overseas tantalum ore is as high as 78%, leading domestic tantalum smelting enterprises have stockpiled raw materials in advance to ensure stable production. Public information indicates that the raw material inventories of some leading enterprises can support stable production for up to one year. In this context, fluctuations in DRC's tantalum ore supply may drive up tantalum ore prices due to tight supply expectations, but from the current market structure, this conflict will not trigger a shortage crisis for downstream end products for the time being.

[SMM Chromium Flash] Zimbabwe's Mines Ministry Inspects Alluvial Chrome Operations in Nationwide Compliance Sweep

Zimbabwe's Ministry of Mines and Mining Development has launched nationwide blitz inspections of alluvial chrome mining operations and processing plants, effective September 25, 2026, to enforce compliance with the country's mining laws. The inspections are initially targeting operations in Mashonaland Central, Mashonaland West and Midlands provinces, before being extended to other parts of the country. Permanent Secretary in the Ministry of Mines and Mining Development Dr Thomas Utete Wushe said the exercise is aimed at ensuring chrome mining activities are conducted within the legal framework. The ministry cited Section 222 of the Mines and Minerals Act [Chapter 21:05], which classifies chromite as a designated mineral, and Section 225, which requires anyone seeking to work an alluvial or eluvial chromite deposit to obtain an order from the Mining Affairs Board. Dr Wushe warned that mining operations found in breach of the regulations could face suspension and other penalties, and said the inspections will also cover chrome processing plants to assess compliance with relevant regulatory requirements. The government has appealed to members of the public to assist authorities by reporting suspected illegal alluvial chrome mining activities. The inspections come amid wider efforts by Zimbabwean authorities to regulate mining activities and ensure mineral resources are extracted and processed in accordance with the law, following earlier findings that the country's chrome output fell sharply in the first quarter of 2026 as more accessible alluvial deposits became depleted, pushing producers toward costlier hard-rock extraction methods.

[SMM Chromium Flash] China's Zero-Tariff Scheme Drives Chrome Volumes Through South Africa's Port of Ngqura

China's zero-tariff policy for qualifying South African exports has significantly boosted demand for dry bulk commodities moving through South Africa's Port of Ngqura, including chrome, magnetite, iron ore and corn, port business strategy manager Xola Mkontwana said. Speaking during a media tour of the adjacent Coega Special Economic Zone in South Africa's Eastern Cape Province, Mkontwana described "exponential growth" in commodity throughput destined for the Chinese market since the policy took effect, saying the zero-tariff treatment has assisted bulk throughput across the port system specifically for commodities including chrome and magnetite alongside iron ore and corn. The zero-tariff treatment applies to qualifying exports from South Africa and 19 other non-least-developed African countries, and officially took effect on May 1, 2026. The framework runs as a two-year, non-reciprocal arrangement through April 30, 2028, expanding duty-free access to the Chinese market for African goods, provided exporters comply with rules of origin and standard customs regulations. The initiative fulfils commitments made under the Forum on China-Africa Cooperation (FOCAC) framework aimed at promoting more balanced bilateral trade and supporting industrialization across the African continent. Mkontwana attributed the surge in Chinese orders to expanding industrial and infrastructure activity in China combined with favorable price realizations for South African mining and agricultural producers. Port of Ngqura, located roughly 20 km northeast of Gqeberha, is South Africa's newest deep-water commercial port and serves as a logistics gateway connecting Eastern Cape minerals, agricultural produce and automotive manufacturing to global shipping lines, offering an additional export route for South African chrome alongside the Richards Bay and Maputo corridors more commonly associated with the country's chrome trade. No specific chrome tonnage or volume figures for Port of Ngqura were disclosed in the report.

Greenland approves Tanbreez mining and closure plans

[SMM Tantalum/ Niobioum Flash] Critical Metals said on 5 October 2026 that Greenland had approved the Mining Plan and Closure Plan for Tanbreez, with the documents signed on 29 September. The approvals run under exploitation licence 2020-54 to 8 September 2050 and specify 19 extractable elements, including tantalum and niobium, alongside zirconium, hafnium and rare earths. This advances Tanbreez from a planning and permitting standpoint, but it is not permission to begin construction immediately. The company still needs activity-specific operating permits covering matters such as environmental management, marine transport, health and safety, and mineral exports, as well as the required financial security. No mining or commercial output has been achieved
