Bolomite
From Star Trek : Freedom's Wiki
Bolomite was a natural substance found on the planet Telsius Prime and extracted through the process of mining.
Ten kilotons of Bolomite were stolen from the Telsius Prime Mining Colony by con artists masquerading as USS Voyager officers. The thieves claimed that they needed the Bolomite for use in omega radiation therapy, though it was unclear if Bolomite was indeed used in the therapy or if this claim was simply part of the con.
