Compass Minerals Confirms Successful Conversion Testing of Sustainable Lithium Brine Resource to Battery-Grade Lithium Hydroxide

The company engaged Veolia Energy, an established technology provider, to conduct lithium chloride to lithium hydroxide conversion testing utilizing a proven, commercially viable conversion process.

The company believes this is the first known conversion to battery-grade lithium hydroxide from the sustainable lithium brine resource originating from the Great Salt Lake.

At a concentration of >56.5% lithium hydroxide monohydrate, the conversion sample meets established battery-grade specifications for the U.S. domestic electric vehicle (EV) and energy storage markets.

Compass Minerals believes this achievement, and the resulting supply it is expected to help enable, is critical for U.S. domestic production of advanced battery materials and support of a growing domestic EV fleet.

As previously disclosed, the company expects to enter the market with a battery-grade lithium hydroxide product by 2025.

“When we first announced the identification of a readily available, 2.4 million ton lithium brine resource, we emphasized that we are evaluating multiple paths forward for development, potential partnerships, and product selection to ensure optimal shareholder value. While that work continues, our progress to date puts us firmly on track for market entry with a battery-grade lithium product by 2025,” said Kevin S. Crutchfield, president and CEO.
