The The Chem-Basin Mine was a mine on the poisonous planet of Quesh that was important in the planet's supply of Quesh venom. Opened in 3647 BBY, the mine had been opened for four years by 3643 BBY. The mine was prone to frequent mishaps, with the very first survey team being nearly suffocated due to an accident with the exported Quesh venom.
During the year of 3643 BBY, Imperial forces were drawing in on an assault at the mine. Fortunately for the miners trapped and captive inside, Republic General Korvan tasked a traveling Republic hero for rescue, as well as to defeat the Imperial's inside. The hero succeeded, and the Empire was forced to abandon their operations at the mine.
