ioneer successfully produces Battery Grade Lithium
Hydroxide from Rhyolite Ridge Pilot Plant feedstock

Thursday, 21 January 2021 – ioneer Ltd (ioneer or the Company) (ASX: INR), an emerging
US lithium–boron producer, today announced that its metallurgy and process engineering
team successfully converted lithium carbonate produced at its pilot plant, into battery grade
lithium hydroxide, a key milestone in ioneer’s lithium hydroxide development path. This
demonstrates ioneer’s ability to provide both high purity technical grade lithium carbonate
and battery grade lithium hydroxide to the burgeoning battery EV sector.
ioneer is highly focused on securing offtake agreements for its lithium products having
already placed under binding offtake initial boric acid production. The ability to supply both
lithium carbonate and lithium hydroxide creates a significant advantage for the Company.
Managing Director, Bernard Rowe said:
“Rhyolite Ridge will be well positioned to meet both North American and global demand
for Lithium carbonate and battery grade lithium hydroxide. As the premier US Project,
ioneer will be uniquely situated to supply the future US electric vehicle platforms of
automotive OEMs. Benchmark Mineral Intelligence predicts that US demand for lithium
carbonate and lithium hydroxide could exceed 344kt by 2025 with nearly no domestic
supply. Additionally, Tesla’s Gigafactory is located 203 miles northwest of the Project site.
The world is in an important transition where renewable power and the electrification of
transportation will play an ever more important role. The successful and timely delivery of
ioneer’s Rhyolite Ridge Lithium- Boron Project in Nevada is a critical early effort to secure
the United States an economic, and sustainable domestic supply of this material which is
a lynchpin for electrification.”
The below table compares the lithium hydroxide produced from Rhyolite Ridge ore against
typical industry specifications for battery grade lithium hydroxide.
