The story

ioneer, Ltd. was listed on ASX in 2007 under the name Global Geoscience Limited

An option over Rhyolite Ridge was acquired in June 2016 and the purchase of a 100% interest in the project was completed in July 2017.

In 2017, Global Geoscience secured ownership of the Rhyolite Ridge Lithium-Boron Project

In 2018, the company changed its name from Global Geoscience to ioneer, which is a combination of the words “ion” and “pioneer.” The new name reflects the company’s new focus and commitment to becoming an important producer of the materials necessary for a sustainable future.

In April 2020, ioneer announced the results of a Definitive Feasibility Study validating the robust economics and viability of Rhyolite Ridge

On November 18, 2020, ioneer became a founding member of the Zero Emission Transportation Association (ZETA) in the US. ZETA is advocating for 100% electric vehicle sales throughout the light-, medium-, and heavy-duty sectors by 2030.
