Tanzania is one of Africa’s most mineral-rich nations, and mining has become a cornerstone of the economy — contributing a growing share of GDP and standing among the country’s top export earners. From the gold belts around Lake Victoria to the tanzanite mines beneath Mount Kilimanjaro, the country offers an unusually broad mineral portfolio. This guide is your starting point for understanding mining in Tanzania — the minerals, the regions, the regulatory framework, and the opportunities for investors and local entrepreneurs.
Why Tanzania’s mining sector matters
Mining is one of the fastest-growing parts of Tanzania’s economy. Gold alone generated billions of dollars in export sales in 2025, and the government’s Vision 2050 places minerals and value-addition at the centre of national industrialisation. Alongside established gold and diamond production, Tanzania is now attracting major investment in critical minerals — nickel, graphite and rare earths — that feed the global energy-transition supply chain.
Tanzania’s key minerals
The country produces and is developing a wide range of minerals. Explore each in detail:
- Gold — the flagship export, mined mainly in the Lake Victoria Greenstone Belt.
- Diamonds — home to the historic Williamson (Mwadui) mine in Shinyanga.
- Gemstones & tanzanite — including tanzanite, found nowhere else on Earth.
- Coal — large reserves in the southern highlands powering industry and exports.
- Graphite — a battery mineral with several large projects under development.
- Iron ore — centred on the Liganga deposit and an integrated steel ambition.
- Nickel — the world-class Kabanga project in the north-west.
- Uranium — the Mkuju River project in the south.
How mining is regulated
Tanzania’s mining sector operates under the Mining Act and is overseen by the Mining Commission (Tume ya Madini). Licences range from small-scale Primary Mining Licences (PMLs) for Tanzanian citizens to large-scale Special Mining Licences (SMLs) for major operations. Investors must also satisfy environmental, local-content and value-addition requirements. Navigating this framework is where professional advice pays for itself — see our mining consultants in Tanzania for guidance on licensing, compliance and investment structuring.
Opportunities for investors and local businesses
Opportunities span the value chain: exploration, small-scale and large-scale mining, mineral processing and refining, equipment supply, logistics and professional services. Local entrepreneurs frequently partner with foreign investors who provide capital and technology, while government policy increasingly favours domestic processing and beneficiation. Many of these opportunities are also accessible through public and private tenders.
