Kenya's Mining Industry: From Soda Ash to Rare Earth Minerals and the Quest to Transform the Economy

Kenya's mining industry is undergoing a transformation from a neglected sector contributing less than 1 percent of GDP to a strategic economic frontier that the government aims to grow to 10 percent of GDP by 2030. The country possesses vast untapped mineral wealth including some of the world's largest soda ash deposits at Lake Magadi, significant titanium sands in Kwale County, globally significant rare earth element deposits at Mrima Hill valued at over USD 62.4 billion, and deposits of gold, gemstones, fluorspar, limestone, and industrial minerals. The Ministry of Mining, Blue Economy and Maritime Affairs and the Kenya Chamber of Mines are working to position Kenya as a strategic mining hub in East Africa.

Major Mineral Resources

Soda ash from Lake Magadi in Kajiado County represents Kenya's oldest and most established mining operation. The lake holds some of the world's largest trona deposits—the naturally occurring mineral from which soda ash is derived—with deposits up to 30 metres thick spanning 80 square kilometres and projected to last for decades. Tata Chemicals Magadi (formerly Magadi Soda Company) has operated the mine since the colonial era, producing soda ash primarily for export to Asian glass manufacturing markets. Soda ash is essential for glass production, detergents, and chemical manufacturing.

Titanium mining in Kwale County, operated by Base Titanium (a subsidiary of Australia's Base Resources), has become Kenya's largest mining operation by value since production began in 2014. The Kwale mineral sands deposit contains an estimated 140.8 million metric tonnes of ore grading 6 percent titanium, yielding ilmenite, rutile, and zircon—minerals essential for pigments, aerospace alloys, and ceramics. Base Titanium's operations have generated significant export revenue, royalty payments, and local employment, while also sparking debates about environmental impacts and community benefit sharing.

Rare earth elements (REEs) at Mrima Hill in Kwale County represent perhaps Kenya's most strategically significant mineral asset. The deposit contains niobium estimated at 105.3 million metric tonnes of ore grading 0.65 percent niobium, with an in-ground value of USD 35 billion, plus rare earth elements valued at USD 62.4 billion, ranking among the top five global REE deposits. These minerals are critical for electric vehicles, wind turbines, smartphones, and defence technologies, making them the subject of growing geopolitical competition between major powers seeking to secure supply chains outside Chinese dominance.

Gold and Gemstone Mining

Artisanal and small-scale gold mining occurs across several counties including Migori, Kakamega, Vihiga, Narok, and Turkana. While individually small, these operations collectively employ tens of thousands of miners and contribute to local economies, though often operating informally with limited regulatory oversight. Environmental concerns include mercury use in gold processing, deforestation, and water pollution. The government has initiated programmes to formalise artisanal mining through licensing, technical support, and mercury-free processing technologies.

Kenya is also known for gemstone deposits including tsavorite (a green garnet found almost exclusively in the Tsavo area), ruby, sapphire, and various semi-precious stones. The Taita-Taveta region is particularly rich in coloured gemstones. However, the gemstone sector suffers from limited value addition, with most stones exported uncut and unpolished, and Kenya capturing only a fraction of the final retail value. Establishing lapidary (cutting and polishing) facilities and gemstone certification centres are priorities for adding value to Kenya's mineral exports.

The Mining Act 2016 and Regulatory Framework

The Mining Act, 2016 provides the cornerstone of Kenya's mining legislation, replacing the outdated Mining Act of 1940. The Act establishes a transparent licensing system with different categories—prospecting permits, mining licences, and artisanal mining permits—administered through the Mining Cadastre Portal. Key provisions include community benefit-sharing requirements, environmental impact assessment mandates, progressive mine closure and rehabilitation obligations, and local content requirements that prioritise Kenyan employment and procurement.

Royalty rates under the Act vary by mineral type: 5 percent of gross value for minerals like gold and titanium, 3 percent for industrial minerals, and 1 percent for construction materials. Of total royalties collected, 70 percent goes to the national government, 20 percent to county governments, and 10 percent to local communities through Community Development Agreements. However, in September 2025, the High Court declared the Mining Regulations 2024 unconstitutional, holding they were promulgated in violation of constitutional principles of transparency and public participation, creating regulatory uncertainty that has temporarily dampened investor confidence.

Environmental and Community Concerns

Mining operations in Kenya face significant environmental and social scrutiny. In Kwale County, concerns about titanium mining impacts include coastal erosion, groundwater depletion, dust pollution, displacement of farming communities, and loss of biodiversity in the ecologically sensitive coastal zone. The National Environment Management Authority (NEMA) requires comprehensive Environmental and Social Impact Assessments (ESIAs) for all mining projects, but enforcement capacity and community participation in monitoring remain limited.

Community benefit sharing remains contentious. While the Mining Act provides for Community Development Agreements and royalty distribution, implementation has been uneven, with some host communities reporting minimal tangible benefits from mining operations generating billions in revenue. Land rights conflicts between mining companies and local communities, particularly in areas with customary tenure systems, present recurring challenges. International best practices increasingly emphasise Free, Prior, and Informed Consent (FPIC) principles for mining developments affecting indigenous and local communities.

Investment Opportunities and Future Outlook

Kenya's mining sector offers significant investment opportunities driven by geological potential, improving regulatory frameworks, and strategic positioning within the East African Community. Priority areas include rare earth element development at Mrima Hill and other deposits, exploration and development of gold resources through modern geological survey techniques, expansion of industrial minerals production (limestone, gypsum, diatomite, kaolin), and development of the emerging oil and gas sector in Turkana County. The government's goal of raising mining's GDP contribution to 10 percent by 2030 requires attracting both large-scale international investors and supporting the formalisation and modernisation of artisanal mining, while ensuring that mineral wealth translates into sustainable development benefits for host communities and the broader Kenyan economy.
