Relating to the production and ownership of brine.

HB 262 defines "brine" as underground salty liquid containing dissolved minerals (like lithium, bromine, and magnesium), excluding groundwater, oil, gas, and related waste. It clarifies that landowners own brine minerals beneath their property as real property, unless otherwise specified in legal agreements. The bill requires the Railroad Commission to create rules for reporting by brine mining operators and regulates "brine mining" operations (extracting minerals from brine) while excluding oil/gas products. This directly affects landowners and businesses extracting minerals from underground brine formations in Texas.
