California's "Lithium Valley" Projects Face Delays as Water and Permitting Questions Mount
Why It Matters: Three years after Lithium Valley was promoted as a game-changer for the state, CalMatters reports that the resources remain untapped as projects falter amid legal challenges and funding problems, and an appeals court recently sent the Hell's Kitchen environmental review back to Imperial County over water and air quality concerns. At the same time, Berkshire Hathaway's CalEnergy completed a direct lithium extraction pilot and plans to launch a demonstration plant by the end of the year, operating it through 2027. The lesson for the whole sector is that credible water data, environmental analysis, and early community engagement aren't optional, and they're the foundation Ion Gradient's research at its California sites is built on.

BORON
Boron Makes Its Critical Minerals Debut as U.S. Confronts a Single Point of Failure
Why It Matters: Despite more than 300 applications ranging from household cleaners to advanced weapon systems, boron avoided the critical designation for years because of a seemingly secure domestic supply from one world-class mine in California's Mojave Desert, until the USGS concluded it was both essential to manufacturing and vulnerable to disruption. That concentration risk is the strongest argument for developing additional domestic boron sources, and California's evaporite basins, including Searles Lake and Owens Lake, are the natural place to look.
