Koppa Mining Site is an aquatic, cavernous biome located under the Delta Island. It is littered with technology left by the Alterra Corporation, most notably Prawn Suits, Thermal Plants, amongst others. Rooms beyond the main shaft contain multiple Rock Punchers. Players should remain wary of Oxygen and Lava Geysers if exploring without a Prawn Suit. The mining site is accessible from the Thermal Spires on the western side of the island through a partially-opened main door at 150 meters of depth that is wide enough for a player or Prawn Suit.
