Africa’s vast mineral wealth is drawing global attention after reports suggested that the United States has only about two months of rare earth elements remaining in its defence stockpile. The development is raising concerns in Washington as geopolitical tensions intensify and demand for strategic minerals continues to grow.
Rare earth elements play a critical role in modern military systems. These minerals support advanced weapons technologies, including missile guidance systems, radar platforms, fighter aircraft and secure communications infrastructure. Without stable supply chains, replenishing defence inventories becomes increasingly difficult.
The urgency has grown as tensions between the United States and Iran escalate. Reports indicate that U.S. military operations that began on February 28 consumed an estimated $5.6 billion worth of munitions within a few days, according to Pentagon assessments. Consequently, the rapid use of military hardware is increasing demand for rare earth materials needed for production and replacement.
At the same time, global supply chains remain heavily dependent on China. Beijing dominates the processing and export of many rare earth elements and strategic minerals used in defence manufacturing. Minerals such as dysprosium, terbium, gallium and germanium are essential inputs for high-performance military technologies.
Industry analysts estimate that minerals linked to Chinese supply or processing chains appear in more than three quarters of U.S. defence platforms. This dominance gives China significant leverage over global defence supply networks.
In recent years, China has also introduced export restrictions on several dual-use minerals that serve both civilian and military applications. These measures have raised concerns among Western policymakers about supply chain resilience and the ability to sustain military operations during prolonged conflicts.
Beyond rare earth elements, China also maintains a strong position in other defence-critical materials. The country produces roughly 48 percent of the world’s antimony, a metalloid widely used to strengthen ammunition alloys and manufacture armour-piercing projectiles. Antimony also supports technologies such as night-vision equipment, infrared sensors and military communications systems.
As Washington seeks to reduce dependence on China-dominated supply chains, attention is increasingly shifting toward Africa. The continent holds some of the world’s largest untapped reserves of strategic minerals, making it a critical player in the global minerals market.
Countries such as the Democratic Republic of the Congo, Zimbabwe, Namibia, Tanzania and South Africa are already emerging as key suppliers in the global critical minerals industry. These nations possess significant deposits that support both industrial manufacturing and defence technologies.
The Democratic Republic of the Congo alone accounts for more than 70 percent of global cobalt production. Cobalt is a vital component used in advanced batteries, electronics and military equipment. Zimbabwe also holds some of Africa’s largest lithium reserves, which are essential for energy storage technologies.
Meanwhile, Namibia and Tanzania are advancing rare earth mining projects designed to supply international markets. South Africa continues to maintain substantial reserves of manganese, platinum group metals and antimony used in high-tech industrial and defence applications.
Botswana has recently entered the spotlight following the announcement of a major rare earth discovery. Early geological assessments suggest that the deposit could contain all 15 rare earth elements, a development that could significantly boost the country’s strategic importance in global mineral supply chains.
Preliminary studies indicate that the high-grade deposit may also contain copper, cobalt, nickel and vanadium. These additional minerals are widely used in industrial manufacturing, clean energy technologies and defence systems. As a result, Botswana could emerge as a new player in the rapidly evolving global critical minerals market.
Global competition for Africa’s mineral resources is intensifying as major powers seek to secure long-term supply agreements. China has already spent more than two decades expanding its presence across Africa’s mining sector. Through infrastructure financing, state-backed mining companies and long-term extraction agreements, Beijing has built deep partnerships across the continent.
However, the United States is now stepping up engagement with African governments and international partners. Washington is exploring new investment partnerships and supply chain initiatives aimed at securing alternative sources of critical minerals.
As global demand for rare earth elements continues to grow, Africa’s mineral resources are becoming increasingly central to global industrial production, technological innovation and defence manufacturing. Analysts believe the continent will play an even larger role in shaping future supply chains as countries compete to secure access to strategic resources.
