The Elesa Mining Union functioned as a protective association for the benefit of miners residing in the town of Elesa, which served as the capital of Ando Prime. Given that the majority of the population consisted of miners and that financial gains were limited, the Union held significant importance. Its operations were conducted from the relatively upscale Miner's Union Hall.
Prior to 27 BBY, the Union's affairs were overseen by the administrator Geon Justic. Justic accepted a bribe from Ree to overlook any legal issues that might arise as Ree and his associate Kaeline Ungasan engaged in the unlawful extraction of Vonium.
