Sangdong Tungsten Mine Restart Signals Strategic Supply Shift
The Sangdong tungsten mine restart marks a major milestone for global critical minerals supply chains. Almonty Industries has completed Phase 1 commissioning in South Korea, bringing the historic mine back after 30 years. The operation now processes 640,000 tonnes of ore annually. It produces about 2,300 tonnes of tungsten concentrate each year.
This restart strengthens supply diversification outside China, which controls over 80% of global output. As a result, the Sangdong tungsten mine restart directly supports Western industrial and defense supply chains. Tungsten demand continues to rise due to its use in high-density military applications and advanced manufacturing.
Moreover, the mine’s ore grade averages 0.51% tungsten trioxide. This level stands nearly three times above the global average. Consequently, the project offers strong long-term economic viability with an expected mine life exceeding 45 years.
Expansion Plans to Double Output at Sangdong Tungsten Mine Restart
The Sangdong tungsten mine restart includes a clear expansion roadmap. Phase 2, scheduled for 2027, aims to double processing capacity to 1.2 million tonnes annually. This expansion will increase output to roughly 4,600 tonnes per year.
Almonty has already invested over $100 million since acquiring the asset in 2015. The redevelopment includes four kilometers of underground tunnels and a modern processing plant. Equipment from Metso supports efficient mineral processing through advanced SAG and ball mills.
Strategic Importance of Tungsten in Defense and Industry
Tungsten plays a critical role in defense and industrial sectors. Military applications rely on tungsten for armor-piercing penetrators due to its density and strength. Additionally, governments such as the United States Department of Defense require secure tungsten supply chains.
Meanwhile, the United States halted domestic tungsten production in 2015 due to cost pressures. Therefore, the Sangdong tungsten mine restart offers a reliable alternative source for allied nations. It also reduces geopolitical risks tied to concentrated supply.
Furthermore, Almonty plans to develop a tungsten oxide facility and a nearby molybdenum deposit. This integrated strategy forms what the company calls the “Korean Trinity.” It aims to create a full mineral value chain from extraction to processing.
SuperMetalPrice Commentary:
The Sangdong tungsten mine restart reshapes the global tungsten landscape at a critical moment. Supply security now drives investment decisions across metals markets. Almonty’s phased expansion positions the project as a cornerstone asset outside China. If execution meets targets, Sangdong could stabilize prices and reduce supply shocks. However, market participants must watch demand growth in defense and clean technologies, which may tighten supply despite new output.
