March 31, 2023ioneer Ltd (“Ioneer” or the “Company”) issued the following statement on new guidance published by the U.S. Treasury Department around material sourcing for electric vehicles:

Ioneer welcomes today’s guidance from the Biden administration in providing further incentives toward building a strong and reliable supply chain of critical materials for the domestic production of electric vehicle batteries.

Ioneer’s Rhyolite Ridge Project is the most sophisticated lithium project in the U.S. and will create good paying jobs in Nevada while helping to reduce the country’s carbon emissions. Once operational, the Department of Energy’s Loan Program Office has estimated that Rhyolite Ridge could reduce annual gas consumption by nearly 145 million gallons and prevent the release of approximately 1.29 million tons of carbon dioxide each year from gas cars.

We look forward to completing the remaining federal permitting steps, producing the resources critical to combating climate change in a responsible and sustainable manner, and delivering a secure source of lithium for the U.S. electric vehicle supply chain.
