Biome expeditions
Koppa Mining Site
Koppa Mining Site is a useful early expedition for minerals and scans that support Prawn Suit upgrades.
WHERE & HOW TO FARM
Koppa Mining Site
Cave entrance in the Thermal Spires southwest of Delta Station, leading down to Koppa Mining Site.
Before you go
- Seaglide and adequate oxygen capacity.
- Light and Scanner.
- Seatruck parked outside the cave entrance; it cannot enter.
- Inventory room for mineral drops and fragments.
Farming steps
- Travel southwest of Delta Station into the Thermal Spires and locate the mine cave entrance.
- Leave the Seatruck in a safe nearby position and note the entrance direction.
- Swim into the mine, following corridors while checking side areas for Shale Outcrops.
- Break Shale and collect any Diamond or other mineral drops.
- Scan Prawn Suit and Drill Arm fragments encountered in the mine.
- Keep a close watch on oxygen and retrace the same corridor rather than exploring every branch.
- Return to the Seatruck, unload, and revisit only if your oxygen and supplies support another pass.
- A beacon near the approach can help identify the entrance again.
- Do not let scanning or inventory sorting consume the oxygen needed for the return.
Repeat, collect and use
The mine can be revisited, but each outcrop or fragment is a one-time pickup. If a pass is cleared, pursue remaining fragments or another resource area.
Common mistakes
- Trying to bring the Seatruck inside: the mine entrance is a swimming route.
- Assuming every Shale piece yields Diamond: drops are variable.
- Continuing into branches without an oxygen margin: turn back early enough to retrace safely.
When to stop or switch
Leave when oxygen is falling toward the return threshold or inventory is full; come back with more capacity for unfinished scans or outcrops.
