WHERE & HOW TO FARM
Where to farm
Cave entrance in the Thermal Spires southwest of Delta Station, leading down to Koppa Mining Site.
Enter on foot from the Thermal Spires and work the mine passages methodically. The visit can provide Diamonds and other Shale drops, alongside fragments worth scanning, but it requires an oxygen-conscious return.
Seatruck parked outside the cave entrance; it cannot enter.
Inventory room for mineral drops and fragments.
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.
Farming tips
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.
