The Geopolitical Race for Critical Minerals: Analyzing the US-Colombia Memorandum of Understanding on Rare Earth Elements

Introduction

In an era defined by the global transition toward green energy, digital transformation, and advanced military technologies, securing the supply chains of critical minerals has become a paramount national security priority. At the heart of this geopolitical chess match are Rare Earth Elements (REEs)—a group of 17 heavy metals indispensable for manufacturing everything from electric vehicle (EV) motors and wind turbines to fiber-optic cables and precision-guided munitions.

Recognizing this strategic urgency, the United States and Colombia recently signed a bilateral Memorandum of Understanding (MOU) focused on cooperation in the exploration, identification, and development of REEs. While the agreement marks a significant diplomatic milestone, industry analysts, geologists, and policy experts suggest that the initiative faces structural hurdles. From a late start in the global mineral race to a historical lack of grassroots exploration, the success of this MOU will depend on moving beyond diplomatic rhetoric and implementing a highly coordinated, scientifically driven strategy on the ground.

Main Facts of the Agreement

The newly signed MOU between the United States and Colombia establishes a formal framework for bilateral cooperation in the mining and geological sectors, with an explicit emphasis on Rare Earth Elements. The agreement aims to leverage American technological and scientific expertise to help Colombia identify, quantify, and eventually extract its untapped mineral wealth, while providing the United States with a geographically secure, allied source of critical minerals.

A Strategic but Belated Partnership

While public diplomacy and international relations experts have welcomed the MOU as a positive step, industry critics argue that the initiative arrives late. The global race to monopolize the REE value chain—spanning exploration, mining, refining, processing, and manufacturing—has been underway for decades, with China holding a dominant position. By entering this arena now, the United States is playing catch-up, attempting to secure supply lines in Latin America that should have been cultivated years ago.

The Missing Phase: Junior Exploration Companies

Geological experts point out a structural flaw in how this bilateral process has been initiated. Historically, successful mining jurisdictions rely on "Junior" exploration companies—highly specialized, risk-tolerant firms that undertake the initial, highly uncertain phases of prospecting and exploration.

In Colombia, this process could have been accelerated by fostering an environment for five to ten junior exploration companies to identify high-potential mineral targets before the high-level diplomatic signing of the MOU. By skipping this grassroots commercial phase, the treaty risks remaining a top-down administrative document rather than a catalyst for active field exploration.

Chronology of the Critical Minerals Race

To understand the context of the US-Colombia MOU, it is essential to trace the geopolitical and legislative timeline that led to its signature.

1. The Trump Administration’s Executive Orders (2017–2021)

During the presidency of Donald Trump, the U.S. government took aggressive steps to address vulnerabilities in the domestic mineral supply chain. Recognizing the threat of foreign monopolies, the administration consulted closely with 14 of the leading American universities specializing in mining engineering and earth sciences.

This resulted in executive orders and bilateral decrees designed to:

• Strengthen academic research centers.
• Allocate significant federal funding to earth science engineering, geology, and mineral processing programs.
• Declare a national emergency regarding the country’s reliance on foreign adversaries for critical minerals.

2. The Biden Administration’s Supply Chain Reviews (2021–2023)

The push for mineral independence continued under the Biden administration, which prioritized the domestic manufacturing of clean energy technologies through legislative packages like the Inflation Reduction Act (IRA). These policies emphasized sourcing critical minerals from allied nations, a strategy known as "friend-shoring," which laid the diplomatic groundwork for partnerships in Latin America.

3. The 2024 USGS Mineral Commodity Summaries

In early 2024, the United States Geological Survey (USGS) released alarming data regarding U.S. import reliance. The report highlighted that the U.S. remains highly vulnerable, relying entirely on foreign imports for several critical minerals. This data added immediate urgency to diplomatic efforts, prompting the finalization of the MOU with Colombia.

Supporting Data: The Reality of U.S. Resource Vulnerability

The strategic necessity driving the U.S. toward Colombia is underscored by hard geological and trade data. According to the United States Geological Survey (USGS) 2024 report, the United States suffers from a 100% import dependency on 11 out of 16 key minerals utilized across strategic economic and defense sectors.

This total reliance on foreign nations—some of which are geopolitical competitors—poses a severe risk to U.S. industrial continuity. For Colombia, this vulnerability represents an unprecedented economic opportunity. Colombia possesses a diverse, highly complex geological landscape that is highly prospective for REEs and other critical minerals, but these resources remain largely unmapped and unquantified.

Perspectives and Strategic Questions

The signature of the MOU has been met with a mix of optimism and skepticism. While the document establishes a framework for cooperation, industry leaders and geological experts are demanding concrete action plans.

Several critical questions remain unanswered:

• What are the urgent geological tasks? To move from a paper agreement to physical extraction, both nations must rapidly deploy field geologists to conduct geochemical and geophysical surveys.
• What is the academic roadmap? How will universities in both nations be integrated? Historically, U.S. administrations have leveraged academia to solve complex engineering challenges. Colombia must now integrate its own premier academic institutions—such as the mining engineering faculties at the Universidad Nacional de Colombia—with their American counterparts to foster joint research in geological exploration and sustainable extraction.
• Who will manage the MOU in Colombia? The Colombian government has yet to designate a dedicated "MOU Project Director" or coordinator to oversee the inter-agency efforts required between the Ministry of Mines and Energy, the National Mining Agency (ANM), and the Colombian Geological Service (SGC).
• Which regions will be prioritized? Clear exploration targets must be established. Regions with historical mining footprints or favorable geological basements must be identified and cleared for exploration under strict environmental and social guidelines.

Implications: Turning Mineral Wealth into Tangible Progress

The implementation of the US-Colombia MOU carries profound implications across multiple sectors, including geopolitics, academic research, and regional economic development.

Geopolitical and Economic Implications

For Colombia, transitioning from a dependency on fossil fuel exports (coal and oil) to critical minerals aligns with the current administration’s goals of economic decarbonization. However, this transition requires massive capital inflows and technological transfers.

By partnering with the United States, Colombia gains access to cutting-edge exploration technologies, satellite mapping capabilities, and advanced laboratory techniques from the USGS. In return, the United States secures a nearby, democratic ally capable of supplying the building blocks of the 21st-century economy, reducing its supply chain vulnerability.

The Academic and Scientific Model

A key differentiator in this partnership is the potential for academic collaboration. By pairing top-tier U.S. mining universities with Colombian institutions, the MOU can drive local capacity building.

This academic synergy ensures that Colombia does not merely export raw materials, but also develops domestic scientific expertise, fostering a new generation of Colombian geologists, metallurgists, and environmental engineers capable of managing complex REE processing chains.

Operationalizing the MOU on the Ground

To prevent this agreement from becoming a mere "photo-op," the private sector must be mobilized. The presence of U.S. mining and exploration companies is vital to bring the operational discipline, capital, and international environmental standards necessary to quantify Colombia’s mineral reserves.

This must be coupled with the active participation of state geological services, creating a robust tripartite alliance between government, academia, and private enterprise.

Conclusion

The Memorandum of Understanding between the United States and Colombia represents a vital strategic framework at a time of intense global resource competition. However, a signed document does not mine minerals, nor does it secure supply chains on its own.

To transform this agreement into a tangible reality, both governments must act with urgency. They must empower junior exploration companies, mobilize academic institutions, designate clear leadership, and initiate aggressive, scientifically sound exploration programs in the Colombian territories. Only then will this MOU transcend diplomacy and deliver lasting economic and technological benefits to both nations.
