Alta Resource Technologies, a Boulder, CO-based company using biochemistry for mineral separation, extended its Seed funding to $10M with the close of an additional $4.4M investment.
The Seed 2 round was co-led by DCVC and Voyager Ventures with participation from Orion Industrial Ventures and In-Q-Tel (IQT).
The company intends to use the funds to expand its technical team, advance commercial pilots, and extend its technology to a broader range of metal targets and feedstocks, including mine tailings, waste streams, and end-of-life products.
Led by CEO Nathan Ratledge, Alta Resource Technologies leverages customizable proteins to separate rare earth elements and other essential minerals from previously untapped sources, expanding access to vital resources while reducing the environmental impact of mining.
Its platform is based on protein engineering innovations developed in partnership with Lawrence Livermore National Laboratory and researchers at Pennsylvania State University.
In addition to private capital, Alta received grant support from federal partners and the State of Colorado.
