Ann: Annual Report to shareholders, page-46

"A company called Lilac Solutions, which has created an ion-exchange technology to separate lithium from a variety of brines, has decided to avoid working with the superheated poisonous brine of the Salton Sea because it’s so difficult to handle. Along with the problems that come from managing a 600-degree liquid, anyone who is trying to extract lithium also has to ensure that these other dangerous materials in the brine don’t escape into the air we breathe.“There are challenges related to the very high temperature and the materials, including toxic materials, that are dissolved into it,” says David Snydacker, Lilac’s founder and CEO, who is used to working with brines that don’t have the same impurities or heat issues."
