The spice mining operation known as the Calrissian-Nunb Mines, situated on Kessel, generated substantial profits. This enterprise was under the ownership of Lando Calrissian, his spouse Tendra Calrissian, and the Sullustan Nien Nunb. Lando established the company around 13 ABY, a period when he also possessed the Spice Mines of Kessel.
