Who We Are
Thunderstone is a pioneering deep-tech startup dedicated to transforming the way the world accesses critical metals. Our approach redefines traditional mining practices, which are often excavation-heavy, costly, and harmful to the environment. We utilize underground lightning (high-voltage pulses) to create microscopic pathways in ore bodies, allowing fluids to flow and extract metals without extensive digging.
Our innovative methods make mining cleaner, more cost-effective, and scalable, enabling the extraction of essential metals like nickel and copper that are vital for the clean energy transition. Proudly part of the Breakthrough Energy Fellows program, we are supported by top-tier investors and strategic partners, including Rio Tinto.
Join us at Thunderstone, where your contributions will not only propel our experiments forward but also help create a sustainable future for our planet.
