FIRST BATTERY GRADE LITHIUM HYDROXIDE PRODUCED FROM KWINANA REFINERY

IGO Limited ( IGO or the Company ) (ASX:IGO) is pleased to announce first and consistent production of battery grade lithium hydroxide from the Kwinana Lithium Hydroxide Refinery (Kwinana), representing an important milestone for the Lithium Joint Venture between IGO (49%) and Tianqi Lithium Corporation (51%).

Based on onsite laboratory tests, the joint venture has successfully and consistently produced battery grade lithium hydroxide over several days. Once product samples have been independently verified, the product qualification process with offtake customers will commence.

IGO’s Managing Director and CEO, Peter Bradford, commented: “We are delighted to announce this important achievement and we congratulate the joint venture team for their focus and professionalism through the progressive commissioning and trial production of Train 1 at Kwinana and the delivery of this important milestone.

“Vertical integration into downstream processing is a key plank in IGO’s strategy and we are proud to be involved in the first production of lithium hydroxide in commercial quantities in Australia. The joint venture’s interest in both the upstream mining asset at Greenbushes and the downstream refinery at Kwinana is emerging as a globally significant, integrated lithium business.”

This announcement is authorised for release to the ASX by Peter Bradford, Managing Director and CEO
