Transition Metal Solutions

Transition Metal Solutions is a biotechnology company that provides custom chemical additives designed to enhance the performance of native microbial communities in mining operations. Their technology functions as a form of prebiotic for heap leaching, identifying and supporting the existing wild microbiomes within ore deposits to increase metal extraction rates. By optimizing these natural biological processes, the company’s drop-in solution aims to improve copper recovery from low-grade sulfides and waste rock without requiring significant changes to existing mining infrastructure or flowsheets. The platform utilizes proprietary analysis of microbial DNA to create site-specific formulations, turning leach heaps into more efficient natural bioreactors.

This technology addresses the critical need for more sustainable and efficient copper production required for the global energy transition. By extracting higher yields from existing assets, the company helps miners reduce operating costs, extend mine life, and minimize environmental liabilities such as acid rock drainage. Founded in 2023 and based in Berkeley, California, the company focuses on scaling its solutions from laboratory testing to industrial pilot programs. While their initial application is centered on copper, they aim to extend their biomining platform to other critical minerals including nickel, cobalt, gold, and zinc. Transition Metal Solutions is supported by a significant seed funding round from various climate and deeptech investors to advance these development and validation efforts.
