The story of Twin Rock Mining Ltd (TRM) begins with the vision of one determined individual who saw untapped opportunities in Tanzania’s mining industry and set out to shape the future. After years of working alongside major mining investors, Dismas recognized how underutilized local resources were, and how they could transform cost structures and redefine the industry. His calling for greater local participation led him to support communities around the mines, offering free financial consulting, establishing local companies to work with foreign investors, and promoting community involvement as both a benefit to locals and a gesture of goodwill from investors.
Driven by a deeper understanding of the gaps and opportunities in the sector, Dismas stepped into a bigger mission: founding YAYA Resources with a partner who shared his vision. What began with two founders grew into a powerhouse of 300 employees in just four years. Backed by a strong equipment fleet and long term agreements, YAYA quickly earned trust across the industry becoming a name that resonated with every major investor, seen by some as a monumental change and by others as a formidable competitor. After consistent growth, asset acquisition, and building strong financial collateral, Dismas embarked on what he considered the lasting mission of his career: the creation of TwinRock Mining Ltd (TRM).
Today, TRM unites seasoned industry professionals with ambitious young engineers, blending decades of proven experience with fresh energy and innovation. This powerful mix enables us to excel across diverse mining environments and deliver results that meet global standards, standing as a true symbol of Tanzanian resilience, opportunity, and excellence.
