EcoPro is a major player in the global cathode market and the EV battery supply chain for US automakers . The binding agreement represents up to a third of our lithium carbonate production in the first three years of operation at Rhyolite Ridge . This is one of the first offtake contracts signed in the lithium chemicals sector for at least two years . It not only demonstrates the level of expected demand for lithium products , but also confidence in the Project and the quality of our lithium battery material products . As the most advanced lithium development project in the US , ioneer is in a strong position to capitalise on the increased demand for lithium products in line with the US Government's efforts to secure critical minerals supply chains for end uses like EVs and renewable energy infrastructure in the US . The awarding of the Class II Air Quality Permit was another significant achievement for ioneer this quarter . This approval is a requirement for project construction and reflects the plans we have to lower emission and minimise hazardous air pollutants across our mining and processing operations . We are looking forward to finalising strategic funding negotiations over the coming quarter as we await further Project permitting and prepare to commence Project construction . ioneer Ltd.
