According to the 2025 Annual Survey of Mining Companies published by the Fraser Institute, Tanzania placed 34th out of 68 mining jurisdictions worldwide, reinforcing its growing reputation as a competitive investment hub on the continent.
Within Africa, the East African nation ranked fourth on the Investment Attractiveness Index, behind Botswana, Morocco, and Zambia, signalling increasing investor confidence in Tanzania’s mineral prospects and regulatory environment.
The country’s overall score rose to 68.04 in 2025, continuing a steady upward trend from 62.75 in 2024 and 46.38 in 2023, according to the survey.
Industry analysts say the improvement reflects strengthening sentiment among global mining executives about Tanzania’s geological potential and the direction of its investment climate.
The Fraser Institute survey, considered one of the mining sector’s most influential benchmarks, combines two key indicators: the Best Practices Mineral Potential Index, which measures geological attractiveness, and the Policy Perception Index, which evaluates investor views on regulatory stability, taxation, and other operating conditions.
Tanzania performed particularly strongly on mineral potential, ranking 15th globally with a score of 75, highlighting the country’s considerable natural resource base and exploration potential.
The country’s policy perception score also improved, rising to 57.61 in 2025 from 55.41 in 2024, suggesting gradual progress in the policy environment that mining investors consider critical for long-term planning and project development.
The survey itself draws directly from industry sentiment as the 2025 edition was distributed to 2,304 senior executives from mining and exploration firms, with 256 responses used to evaluate 68 jurisdictions globally.
Participating companies reported $4.2 billion in exploration spending in 2025, underscoring the survey’s importance as a barometer of where global mining capital is likely to flow.
For Tanzania, the improved ranking strengthens the government’s broader push to position mining as a pillar of economic transformation. Authorities have been working to expand exploration, strengthen institutional frameworks, and increase local participation across the mining value chain.
With competition for global mining investment intensifying, Tanzania’s rising profile suggests the country could become one of Africa’s most closely watched exploration frontiers in the coming years.
