Kassoti
this form of spice was mined on Naboo's smallest moon, during the years leading up to the Clone Wars. Kassoti spice had to be processed in a plasma bath shortly after mining, and the primary processing facilities were located near Naboo's major starports. All kassoti mining was controlled by the Naboo Moon Mining Union. Just before the onset of the Clone Wars, mining ships were forced to land at remote starports, when Queen Jamillia closed off the larger ports so that refugee traffic could land safely. The Union began a series of "sit-in" protests, leaving their ships in port and preventing refugee ships from landing, in protest of the loss of spice caused by delays in getting it from remote ports to the larger cities for processing.
