Bolomite
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  officers. The thieves claimed that they needed the bolomite for use in omega radiation therapy for orphans on the Narva colony. Bolomite was implied to be of relatively low value, dilithium was noted to be twice as valuable as bolomite by mass. ()
