Ioneer Ltd published an updated resource report on its Rhyolite Ridge lithium-boron project in Nevada, USA. Conducted by WSP USA Inc., (formerly Golder Associates USA Inc.), the report now estimates Rhyolite Ridge’s Mineral Resource deposit at 360 million metric tons (mt), containing 3.4 million mt of lithium carbonate equivalent and 14.1 million mt of boric acid equivalent. That reflects a 168% increase in lithium carbonate and 18% increase in boric acid (collectively a 145% increase in mineralized resource) estimates in an April 2020 Ioneer Mineral Resource statement.

“Rhyolite Ridge is a once-in-a-generation opportunity to produce a critical and reliable source of lithium and boron for the U.S. electric vehicle supply chain,” said James Calaway, the executive chairman of Ioneer. “We look forward to completing the important federal permitting process and getting to work.” Once federal permitting and construction is complete, Rhyolite Ridge is expected to quadruple current U.S. lithium chemical output.
