The room is cylindrical and, as the name implies, is full of Phazon. Upon first entry, the tunnel is blocked by (unscannable) Bendezium. Samus must first traverse it in order to get to the Omega Pirate. Many rocks are in the way, which Samus must with Morph Ball Bombs or Power Bombs.
- Artifact of Newborn
- Once Samus gets the Phazon Suit, she can safely traverse through the Phazon-filled area of the tunnel to reach this artifact.
- "High levels of Bendezium present in object."
- Getting the Artifact of Newborn without the Phazon Suit is possible, but requires full Energy Tanks and careful timing. 
- This particular room is called a mining tunnel, but there seems to be no equipment in or nearby it, suggesting it was abandoned by the Space Pirates for unknown reasons.
