Rhyolite Ridge Project
Rhyolite Ridge is one of two advanced lithium projects in the U.S. and is fully funded to a Final Investment Decision. Once operational, Rhyolite Ridge is expected to be a low-cost lithium site, due to the valuable boron co-product and innovative cost saving measures embedded in our sustainably designed operations.
Over the course of its lifetime, modelled on a 26-year production, Rhyolite Ridge will help power upward of 50 million electric vehicles.
Because our operations will be on-site and our materials will not be shipped to a separate processing facility, Ioneer can more quickly and efficiently produce lithium carbonate, critical for the EV battery supply chain.
