Mining Mineral Manufacturing

The Democratic Republic of Congo (DRC) is extremely rich in natural resources. DRC's largest export is raw and partially refined minerals. MES began its journey in 2009 when we recognised an opportunity to diversify into tin, tantalum and tungsten.

The 3 Ts with MES

We are the biggest exporter and refiner of tin, tantalum and tungsten from DRC. With our five major concessions, multiple processing facilities and a constant push for growth and development, MES hopes to become a global leader of the 3 Ts market, while maintaining conflict-free and OECD-approved traceability standards.


The 3Ts have significant opportunities for value addition and usage in tech-nological, aerospace, defence, and more industries. They all carry a very high strategic value for any country which is able to harness and maximise their potential.
