The United States is supporting Kenya’s initiative to develop a domestic processing capacity for critical minerals from the giant deposit of Mrima Hill in Kwale County, making Kenya a key player in an increasingly contested landscape for rare earths supply chains.
The mineral deposit in question is believed to be valued in the tens of billions of dollars, while the number often cited of $62.4 billion can be traced back to historical mineral resource figures. Kenya is looking for investments in developing the mine, while the US wants to see processing, technology transfer and employment created in Kenya rather than just export of minerals.
What Is the Mrima Hill Project?
The Mrima Hill project, found in Kwale County of the Kenya coastal region, holds REEs and niobium, which have been classified as strategic minerals in Kenya.
According to the government’s 2026 tender documents, the Kenyan government views niobium and rare earths as strategic minerals and is looking for a developer who can set up a process plant at the site. According to the documents, it requires all bidders to show their commitment towards the environment and communities.
From the latest geological data from the government, there appear to be huge indicated and inferred resources; however, the government has said that there has been no economic feasibility study done for the project yet, making the commonly cited $62.4 billion figure merely a resource valuation figure.
Why Is the US Interested in Kenya’s Rare Earths?
The US support for this comes amid efforts to wean itself off critical-mineral supplies from China.
US Assistant Secretary of State for African Affairs Frank Garcia explained that the United States is ready to assist Kenya in creating a mining sector that will be transparent and supportive of communities, in addition to helping the US improve its global supply chains. In addition, the US International Development Finance Corporation is financing more African critical minerals projects.
Why the project is strategically important can be easily seen. Rare earth elements play an important role in high-strength magnets and many advanced technologies, while niobium is used in high-strength steel production. China holds dominance over much of the process chain of rare earths, and thus an alternative source becomes more valuable for the US and its allies.
Processing Minerals Locally Can Provide Jobs
For Kenya, the opportunity to extract minerals is not enough. What the country needs is to keep more of the process locally.
According to Business Daily, the proposed project with the backing from the US can include factories, workers’ training, technology transfer, and other industries located around the deposits. President William Ruto has also been promoting local processing as job creation opportunity.
As indicated in its tender documentation, Kenya expects potential developers of the rare earths in question to prove that they can design and contract the installation of processing facilities in the country, and not limit themselves to extraction and export.
China Competes on a Geopolitical Level
This project is increasingly turning into one more aspect of a much bigger competition between Washington and Beijing over strategic metals.
While Kenya had already talked to China about mineral investments and manufacturing in the country, now the US offers an alternative option with emphasis on processing and supply chains that will benefit the Kenyan people in a way that goes beyond simple extraction of resources.
Nevertheless, this project is still not a concluded mining deal – Kenya is considering competing bids, including those submitted by US-based Critical Metals Corp and Australian RareX company.
What Is Next?
First and foremost is to take advantage of the political and investment interest to create a profitable venture by ensuring that the environmental, community and transparency considerations are taken into account.
The requirements set out under Kenya’s tender process include local processing and sustainability. With a successful Mrima Hill venture, there will be an opportunity to see if African mineral producers can gain from their minerals and become strategic partners in the global critical minerals race.
