Ksh8 Trillion Mrima Hill Treasure: What Australian Firms Promise Kenya in Race Against US and China

Australian mining companies RareX and Iluka Resources have unveiled plans to develop Kenya’s estimated Ksh8 trillion Mrima Hill mineral deposits, promising local processing, skills development and business opportunities if they secure the highly sought-after project in Kwale County.

The proposal places Kenya’s mineral wealth at the centre of growing international competition for critical minerals used in advanced manufacturing, technology and other industrial applications.

The consortium has submitted its proposal to Kenya’s Ministry of Mining following a competitive tender process to determine who will develop the deposits. The project targets rare earth elements, niobium and other minerals believed to hold significant economic potential.

Under the proposal, the companies intend to combine mining and initial processing in Kenya with advanced refining in Australia. The arrangement could allow Kenya to participate in mineral production while supplying international markets with more highly processed materials.

RareX says the project would prioritise local value addition and create opportunities for Kenyan businesses to participate in the supply chains associated with the deposits.

The companies have also identified phosphate and manganese by-products as potential areas for developing additional industrial activities. If implemented, these plans could expand the economic benefits beyond the extraction of the primary minerals.

A central component of the proposal is the use of Iluka Resources’ Eneabba rare earth refinery in Western Australia. The facility would process rare earth concentrates from Mrima Hill into separated rare earth products for potential supply to international markets.

According to the proposal, the targeted markets include the United States, Europe, Japan and South Korea, regions with industries that require reliable supplies of critical minerals.

The proposed arrangement would connect Kenya’s mineral resources to established international processing infrastructure while potentially opening access to customers in major industrial economies.

However, the extent of the benefits Kenya would receive would depend on the final project structure, the amount of processing undertaken locally and the commercial terms agreed with the successful bidder.

The consortium has also proposed training programmes and scholarships aimed at developing Kenyan expertise in mining and mineral processing.

The plans include a partnership with Australia’s Curtin University to support technical training, knowledge transfer and the development of local skills. Such initiatives could help Kenyan workers and professionals gain experience in specialised areas of the mining industry.

The companies have further pledged to engage communities, protect the environment and preserve cultural heritage before undertaking physical activities at the site.

These commitments are particularly important because the development of mineral deposits can raise questions about land use, environmental protection, livelihoods and the interests of communities living near proposed mining areas.

The proposal also includes further assessments of the mineral resource to establish its characteristics and development potential. The consortium intends to consider the feasibility of underground mining and address the eventual closure and rehabilitation of the mining area.

These assessments would be important in determining how the deposits could be extracted, the infrastructure required and the environmental safeguards needed throughout the project’s life cycle.

Despite the scale of the proposal, the promised benefits are not guaranteed. RareX and Iluka must first secure the development rights, while the commitments outlined in their bid would need to be translated into clear and enforceable arrangements.

Kenya’s ability to negotiate favourable terms could determine how much revenue, employment, technical expertise and industrial activity the project generates locally.

The Australian proposal comes as the United States steps up efforts to secure access to Kenya’s critical mineral resources.

In September, US officials indicated that Washington was prepared to support local mineral processing, worker training, technology transfer and the development of industries around the deposits.

China is also seeking a role in the competition for Mrima Hill, with Chinese-backed bidders among the groups pursuing development rights.

The competing proposals highlight the growing international importance of critical minerals and the efforts by major economies to secure dependable supply chains for strategic industrial materials.

For Kenya, the competition presents an opportunity to negotiate investment that extends beyond exporting raw minerals. Local processing, employment, technology transfer and the participation of Kenyan companies could become key measures of the project’s long-term value.

The government’s decision on the tender will therefore be significant in determining which investor gets the opportunity to develop the deposits and what obligations will accompany the award.

Ultimately, the success of the Mrima Hill project will depend not only on the estimated value of the minerals underground but also on the terms of the agreement, the feasibility of the proposed operations and the extent to which promised benefits reach Kenyan workers, businesses and surrounding communities.
