Piran Rwanda Limited, Eurotrade International Limited and Rutongo Mines Limited are established as three separate, privately held companies. They all have a strong track record of mining and exploration of tin, tungsten and/or tantalum in Rwanda and are committed to incorporating responsible mining practices into assets previously acquired from the Rwandan government.
In May 2022, the three companies’ shareholders joined forces to form Trinity Metals Limited (“The Group”) under equity backing from Techmet, a UK-based private industrial company working to secure the technology metal supply chain in a world with rapidly increasing demand. Techmet, Trinity Metals’ majority shareholder, works with a number of investment partners including the US Development Finance Corporation (DFC) to fund its portfolio. Additional shareholders include Piran Resources, the parent company of Piran Rwanda Limited and the Rwandan Government, represented by Ngali Holdings Limited.
The consolidation of the three companies led Trinity Metals to its position as a leading mining company and private sector employer. The board of directors was appointed in May 2022 with representation from the major shareholders to oversee the company’s strategy and governance in Rwanda.
The three-way alliance, by design, builds upon the strengths of each of the three companies to achieve operational synergies such as increased production capacity, greater supply chain leverage, improved career growth opportunities for employees and stronger community and government relations.
