Rwanda showcased investment opportunities in its mining sector to a group of U.S. investors during the U.S.–Africa Investment Summit held on June 3 in Washington, D.C.
The discussions focused on Rwanda’s 3Ts minerals — tin, tantalum and tungsten — with particular emphasis on tungsten, which officials described as a key strategic mineral for global supply chains.
Alice Uwase, chief executive officer of the Rwanda Mines, Petroleum and Gas Board (RMB), told investors that Rwanda offers strong investment opportunities in mining and is positioning itself as a reliable supplier of critical minerals.
She said Rwanda is currently Africa’s leading producer of tungsten, highlighting the country’s growing production capacity and investment potential in the sector.

The summit brought together U.S. government officials, African ministers, investors, miners, minerals processors and manufacturers to discuss investment opportunities in commercially viable critical minerals projects and strengthen cooperation across supply chains.
Most of Rwanda’s tungsten production comes from the Nyakabingo mine in Rulindo District, which is operated by Trinity Metals Group. The company has expanded production significantly since beginning operations in 2022.
Tungsten is used in hard metals applied in construction, aerospace, defense and advanced manufacturing, making it a critical material in global industrial supply chains.
Trinity Metals exports processed wolfram concentrate with an estimated purity of about 68%, which is further refined internationally to levels of up to 99.9%.
In September 2025, Trinity Metals shipped its first containers of processed wolfram derived from tungsten to the United States, arriving in Towanda, Pennsylvania. The shipment was delivered to Global Tungsten & Powders, which processes tungsten powder for industrial use.
