SB 1763 formally establishes ownership rights for brine minerals in Texas. It defines "brine minerals" as including lithium, bromine, magnesium, and other valuable substances found in subterranean brine deposits. The bill states that, unless otherwise specified in a legal agreement, the owner of the mineral estate also owns the brine minerals beneath the land. It further clarifies that brine mining is distinct from oil and gas production and sets up a regulatory framework under the Texas Railroad Commission, which will oversee reporting requirements for brine production and injection wells​.
