Colombia’s newly elected president has moved to restore diplomatic and strategic ties with Washington, reversing tensions from the previous administration. Early last month, the two nations formalized an agreement to expand cooperation on critical minerals essential to U.S. military and economic interests.
The partnership addresses a strategic vulnerability in American supply chains. The Department of the Interior’s 2025 Critical Minerals List identifies 60 materials vital to national security and the economy. Antimony and tungsten are crucial for munitions and weapons systems, while gallium, germanium and cobalt support semiconductor and advanced electronics manufacturing. Lithium powers rechargeable battery technology. China’s control of global critical mineral supply chains has given Beijing considerable geopolitical leverage, demonstrated when it imposed export restrictions on gallium, germanium and antimony destined for the United States. Although those restrictions were suspended, the suspension is scheduled to expire on November 27, 2026.
Colombia’s mineral wealth remains largely undeveloped despite its long history of extracting oil and coal. The country possesses deposits of silver, platinum, nickel, copper, tungsten, antimony, cobalt, manganese and magnesium relevant to defense, aerospace and technology sectors. Recent discoveries have identified significant deposits, including a high-grade tungsten, gold, silver and copper site in Caldas department that represents Colombia’s first known hard-rock tungsten deposit. Another prospect west of Medellín contains substantial silver, gold and antimony reserves. The Cerro Matoso mine makes Colombia South America’s second-largest nickel producer.
Developing these resources could generate substantial export revenues and government royalties while providing Washington access to critical minerals closer to home. The agreement establishes a framework to accelerate mining projects, improve geological mapping, facilitate technology transfer and streamline permitting. It also promotes recycling of critical minerals and addresses supply chain resilience while countering anti-competitive practices.
