Tanzania has strengthened its position as one of Africa’s leading destinations for mining investment, according to the latest global survey released by the Fraser Institute.

The Annual Survey of Mining Companies 2025 ranks Tanzania as the fourth most attractive mining jurisdiction in Africa, reflecting the country’s strong mineral potential and growing interest from international exploration companies.

Globally, Tanzania placed 34th in the overall Investment Attractiveness Index, which evaluates mining jurisdictions based on a combination of geological potential and government policy factors that influence investment decisions.

Strong Mineral Potential Drives Investor Interest

One of Tanzania’s key strengths in the survey is its geological potential, where the country ranked 15th globally. This high ranking highlights the country’s abundant mineral resources and the significant opportunities available for exploration and development.

Tanzania is home to major deposits of gold, graphite, nickel, and other critical minerals that are increasingly important to global supply chains, particularly for energy transition technologies.

Policy Environment Still a Constraint

Despite strong mineral potential, the report indicates that policy factors continue to influence Tanzania’s overall ranking. The country placed 48th globally in the policy perception index, which measures investor views on regulations, taxation, political stability, and other governance factors affecting mining operations.

However, Tanzania’s policy score improved compared with the previous year, suggesting gradual progress in the investment environment.

Regional Competition

Within Africa, Tanzania ranks behind Botswana, Morocco, and Zambia, which occupy the top three positions on the continent in the latest survey.

Still, Tanzania’s performance places it ahead of many other African jurisdictions competing for mining exploration capital.

Importance of the Fraser Institute Survey

The Fraser Institute’s annual survey is widely followed by investors, exploration firms, and policymakers. It evaluates jurisdictions worldwide based on mineral potential and public policy factors, helping companies determine where to allocate exploration budgets.

The latest results highlight Tanzania’s strong geological endowment while underscoring the importance of continued policy improvements to fully unlock the sector’s investment potential.
