About Endolith

Endolith is a biotechnology company that has developed a method to extract critical minerals, such as copper and lithium, from low-grade ores that are typically uneconomical to mine. The company utilizes microbes, which it refers to as "earth's oldest miners," in a process that is enhanced by bioengineering, synthetic biology, and artificial intelligence. This approach to biomining is designed to increase the recovery rates of minerals while also being more sustainable and having a lower carbon footprint compared to traditional mining methods.

Read full description

The company's platform is tailored to the specific ore composition of each mine, creating customized microbe colonies to optimize extraction. Endolith serves the mining industry, with a notable partnership with major mining company BHP. The business model appears to be centered on providing its specialized bio-extraction technology and services to mining companies, enabling them to generate revenue from previously challenging or unprofitable ore bodies.
