ioneer Ltd. is a lithium-boron supplier founded in 2001 and headquartered in Sydney, New South Wales. The company states that they are "intent on pioneering the production of materials necessary for a sustainable future." They are developing a Nevada mine site known as Rhyolite Ridge in order to be a future producer of lithium-boron.The Rhyolite Ridge project has raised controversy as it may threaten some populations of a rare wildflower, Tiehm's buckwheat (Eriogonum tiehmii), an edaphic endemic to the project area. The conflict over the conservation of the plants has sparked debate over whether the sustainability benefits of lithium extraction outweigh the fate of the buckwheat.
