South Korean Sangdong Mine Set to Supply U.S. with Tungsten

The Sangdong mine in South Korea is preparing to supply the United States with a critical mineral: tungsten. With millions of tons of this essential resource located deep in the eastern mountains, the mine is now operational after being closed for over 30 years. Mining company Almonty Industries has taken on the task of reopening the facility, which is crucial for the U.S. defense sector.

The reopening comes at a time when the U.S. is seeking to diversify its sources of tungsten, a metal vital for military applications including tanks, fighter jets, and advanced weaponry. According to Lewis Black, CEO of Almonty Industries, “The U.S. is right to do this, there is no choice. The status quo cannot be returned to.” This statement underscores the urgency of establishing a reliable supply chain for critical minerals as geopolitical tensions with China continue to escalate.

Strategic Importance of Tungsten

Historically, tungsten has played a pivotal role in warfare. During World War II, Allied nations fought to prevent the flow of tungsten from Spanish deposits to Nazi Germany. Today, the U.S. is focused on ensuring its own supply, particularly after China threatened to leverage its dominance in the rare earths and critical minerals sectors during the recent trade disputes.

The demand for tungsten is driven by its unique properties, which allow it to withstand extreme temperatures and pressures, making it indispensable in military technology. Black assured U.S. officials during a recent visit to the White House that his company would meet the national security needs for tungsten, stating, “For U.S. national security, yes.”

In May 2023, the U.S. entered a minerals agreement with Ukraine to enhance cooperation in developing oil, gas, and mineral resources. This arrangement is part of a broader strategy to ensure energy security and support Ukraine in its ongoing conflict with Russia.

Operations at Sangdong Mine

Access to the Sangdong mine reveals a complex network of tunnels where tungsten deposits are located. CBS News recently reported on the mining process, highlighting the challenges involved in extracting tungsten, which is as heavy as gold yet as fragile as ceramic. Black stated that once the mine reaches full operational capacity in early 2024, it is expected to produce 1.2 million tons of tungsten ore annually. This output will secure a long-term supply for the United States, addressing a critical gap in its mineral resources.

As the global market for tungsten evolves, the reopening of the Sangdong mine represents a significant step for U.S. defense strategy and resource independence. The focus now shifts to ensuring that this supply can be sustained and utilized effectively to meet the nation’s defense needs.

This development is not only crucial for military applications but also serves as a reminder of the interconnectedness of global mineral supply chains and the importance of strategic partnerships in securing essential resources.
