Rhyolite Ridge Project

Advancing the Rhyolite Ridge Lithium-Boron Project in Nevada.

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.

Location

  • Located in Esmeralda County, the most sparsely populated county in Nevada
  • Accessible to the state’s Lithium Loop and located between Las Vegas and Reno
  • On federal (Bureau of Land Management) land in the Silver Peak Range at approximately 1,800m altitude
