GF Securities Co.,Ltd. (ASX: 000776) has released a research report stating that on the supply side, global tantalum supply remains highly dependent on hand-mined ore from African countries such as the Democratic Republic of Congo and Rwanda, resulting in weak production stability, while a large number of potential new projects are still in the exploration or feasibility study stage and are unlikely to supplement supply in the near term.
On the demand side, continuously rising capital expenditure in the AI sector is persistently driving demand for AI-related tantalum capacitors, and the strong downstream outlook is expected to support an upward shift in the center of tantalum consumption. Therefore, the firm believes that tantalum industry supply and demand will continue to tighten and support tantalum prices moving higher.
A Scarce and Refractory Critical Strategic Minor Metal
Tantalum has an extremely low crustal abundance of only about 1 to 2 ppm, and possesses a high melting point of 2,980 degrees Celsius, strong corrosion resistance, and excellent dielectric properties. In terms of resource distribution, global proven reserves are highly concentrated in Australia and Brazil, which together account for more than 90 percent, but constrained by associated mining and high costs, supply from Australia and Brazil is being released slowly. Although core African producing regions such as the Democratic Republic of Congo and Rwanda contribute nearly 80 percent of global output, they rely mainly on surface weathered placer deposits and artisanal and small-scale mining, with compliant proven reserves meeting international standards being scarce. Overall resource endowments are highly uneven and the degree of proven reserves is severely insufficient.
Supply Side: Frequent Geopolitical Disruptions and Limited Potential New Capacity
The artisanal mining model in Africa determines that its supply chain is highly fragile and opaque. In January and March 2026, the Rubaya mining area in the Democratic Republic of Congo, which accounts for about 15 percent of global supply, experienced large-scale collapses and full production halts, causing the global supply gap to widen sharply and driving tantalum prices higher. Non-African producing regions also struggle to provide supply elasticity. Hard rock tantalum mines in Australia are mostly associated with lithium mines, and high mining costs combined with lithium cycle disruptions have caused capacity release to lag severely behind reserve status. Brazil, as the second-largest supplier, has seen production fall significantly from its peak in recent years. China's resources are mostly low-grade and difficult-to-process lean ores, and its external dependence remains high. In terms of global new project progress, more than half of the world's tantalum mining projects are still in early exploration or feasibility study stages, and mine development cycles are generally long, making it difficult to form effective large-scale supply in the short term.
Demand Side: AI Demand Opens a New Prosperity Cycle
The largest downstream consumption area for tantalum is tantalum capacitors, accounting for 33 percent. AI servers, due to surging power consumption and higher transient power supply response requirements, are driving both the usage volume and value of polymer tantalum capacitors per unit higher. Leading manufacturers such as Yageo and KEMET have seen strong earnings growth and have continued to raise product prices, while on the raw material side, domestic tantalum powder exports have maintained substantial growth. In addition, the rising share of wafers at advanced process nodes below 28 nanometers is driving rapid volume growth in tantalum targets used for copper interconnect barrier layers in semiconductors. Combined with demand for tantalum in high-end nickel-based superalloys driven by aero engines and industrial gas turbines, the strong AI industry outlook is expected to support an upward shift in the center of tantalum consumption.
Risk Warnings
Risks include macroeconomic fluctuations, downstream application progress falling short of expectations, and supply-side capacity release progressing faster than expected.
