The global tungsten market is experiencing significant shifts driven by escalating geopolitical tensions between the United States and China. With China dominating the production and supply of this critical mineral, the strategic importance of tungsten has never been more pronounced. The metal's unique properties make it indispensable in various high-tech industries, and any disruptions in its supply chain could have far-reaching implications.
China's Export Restrictions: A Strategic Maneuver
While explicit export restrictions on tungsten have not been officially announced as of 2023, China has a history of leveraging its dominance in critical minerals as a geopolitical tool. Previous restrictions on materials like rare earth elements and, more recently, tighter controls on the exports of antimony, gallium, and germanium signal a calculated approach to managing mineral supply chains. This calculated approach mirrors China's recent policies, as seen in their new export restrictions impacting global battery and mineral technologies.
Such maneuvers not only intensify trade tensions but also prompt other nations to reassess their dependency on Chinese mineral exports. The potential inclusion of tungsten in China's export control list would have significant repercussions for industries globally, particularly in countries like the United States that lack domestic production.
Why Is Tungsten So Critical?
Tungsten stands out as one of the most critical materials for technology and defence industries. Its exceptional properties—such as the highest melting point of almost all elements at approximately 3,400°C and significant density—make it indispensable in applications where high-temperature resistance and durability are paramount.
Key industries reliant on tungsten include:
- Aerospace and defence systems: Used in missile and rocket components, armour-piercing ammunition, and aerospace applications due to its superior strength and heat resistance.
- Electronics manufacturing: Essential in the production of semiconductors, electrodes, and electrical contacts.
- Automotive engineering: Employed in manufacturing high-performance engine components and tooling.
- Advanced manufacturing technologies: Utilised in 3D printing and as a critical material in cutting, drilling, and machining tools due to its hardness.
The paradoxical role of mining in the clean energy transition also underscores the importance of critical minerals like tungsten.
Geopolitical Supply Chain Dynamics
With China producing approximately 80% of the world's tungsten supply, the United States and other countries find themselves in a vulnerable position. The lack of domestic production means that any disruption in Chinese exports could have immediate and severe impacts on manufacturing and defence capabilities. Given the strategic significance, there is growing urgency for nations to diversify their mineral supply chains and reduce dependency on a single source.
Australia is emerging as a key player in global mineral exploration, with record investments and critical discoveries contributing to supply chain diversification.
The US Government's Strategic Response
In response to these challenges, the US government has been exploring measures to mitigate supply risks associated with critical minerals like tungsten. While specific policies regarding tungsten are evolving, efforts include:
- Funding domestic and allied mining projects: The Department of Defense has allocated funds to support the development of critical mineral projects within the US and allied countries.
- Stockpiling strategic minerals: Increasing reserves of critical materials to buffer against supply disruptions.
- Exploring alternative supply sources: Actively seeking partnerships with countries like Australia and Canada to secure more stable supply chains.
Emerging Alternative Supply Sources
Canadian and Australian Opportunities
Countries like Canada and Australia are stepping up to fill potential supply gaps. For instance, Canada's Almonty Industries is developing the Sangdong Mine in South Korea, which is expected to become a significant non-Chinese source of tungsten. Similarly, Australia is advancing several projects that could bolster global tungsten supply. The country's rich mineral resources and stable political environment make it an attractive alternative.
These strategic lithium investments in Australia are reshaping the future of mining, highlighting the nation's growing role in supplying critical minerals.
The Mt Mulgine Project: A Potential Game-Changer
Australia's Tungsten Mining NL is developing the Mt Mulgine project, representing a promising solution to the impending tungsten supply crunch. Key highlights of the project include:
- A substantial resource: Boasting an estimated 259 million tonnes of mineral resources.
- High tungsten oxide concentration: With an average concentration of 0.11% tungsten oxide.
- Long-term supply potential: Capable of supplying approximately 10% of the world's tungsten demand for the next 25 years.
The development of Mt Mulgine could significantly reduce global reliance on Chinese tungsten supplies and enhance the security of supply chains for critical industries. China's economic policies have ripple effects on mineral markets globally, similar to how China's economic stimulus boosts Australian iron ore miners.
