The Phazon Mines are the far southeast area of Tallon IV, located south of the Tallon Overworld and southeast of the Magmoor Caverns. The Mines are the core of all Space Pirate activity on Tallon IV. As the name suggests, the Phazon Mines were created by the Pirates to mine Phazon, a valuable energy source for them. They also had many labs within the mines, and a few Metroid quarantines. The sky in this area is a hazy pink, suggesting the Pirates have heavily polluted this area.
