Koppa Mining Site Biome

Overview

The 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 and 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.

Access

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. The gate is located approximately 380 meters Southwest of the Delta Station beacon.

  • Player/Prawn Suit: Enter through the main door.
  • Seatruck: Access through the main door is hard but doable. Entering it through the top of the door is easiest. There is a small cave opening, located on the western side of Delta Island, in the Thermal Spires that leads to the other side of the door and it is big enough for the Seatruck to go through.
  • Thermal Spires Caves: It can also be accessed from the Thermal Spires Caves, through the large cave system under Delta Island's dock which leads into a mineral-rich chamber, at the deepest point of the site. A Prawn Suit with a drill arm is recommended for optimal gains from this chamber.

Description

The mining site is a mixture of natural, rocky cave systems and man-made shafts mined out by Alterra. The entry room contains a Data Box with a Moonpool blueprint and an Oxygen Plant. In the middle of the room there's a deep elevator shaft that leads to the rest of the facility.

Following the rail system at the base of the shaft leads the player through some Hydrothermal Spires, where Thermal Plant fragments can be found, and towards the first chamber. The first chamber contains multiple Prawn Suit fragments, a Laser Cutter fragment, a Data Box with a Scanner Room blueprint, and a Prawn Suit Jump Jet Upgrade in a terminal beside one of the work stations.

Down the tunnel to the left is a small chamber with an Alien Statue. The tunnel to the right leads to the second chamber containing more Prawn Suit fragments and Prawn Suit Drill Arm fragments, a Data Box with a Headlamp blueprint. This chamber contains an extensive amount of Large Resource Deposits, mostly Copper Ore, Diamond, Ruby, and Titanium.
