Diamond is a valuable crafting material; Koppa Mining Site offers an early focused search, while deeper areas can supply more later.

WHERE & HOW TO FARM
Where to farm
Koppa Mining Site, entered through the Thermal Spires southwest of Delta Station; later Shale Outcrops and loose resources in deep biomes such as Crystal Caves.
Search mine tunnels and Shale Outcrops at Koppa before relying on deep-water routes. Shale drops are variable, so treat each visit as a collection sweep rather than a guaranteed yield.
Seaglide for the mine approach and return; a Prawn Suit with Drill Arm for large deposits encountered later.
Reach the Thermal Spires southwest of Delta Island and locate the cave entrance to Koppa Mining Site.
Leave the Seatruck outside; it does not fit through the entrance.
Follow the mine passages while keeping track of the way back to the entrance.
Break Shale Outcrops and collect any loose Diamonds you encounter.
Scan useful fragments on the route, but keep the Diamond search focused on outcrops and loose material.
Return to the vehicle before oxygen becomes critical and store the haul at base.
On later deep expeditions, collect loose Diamonds or mine large deposits when your Prawn Suit is equipped.
Farming tips
Carry enough oxygen and use a light so you can recognize branches on the return route.
Perimeter Defense can help protect a Seatruck on exposed approaches when available.
Repeat, collect and use
You can revisit the mine for remaining outcrops, but each outcrop is a single break and its drop is not guaranteed. Later biome sweeps provide additional opportunities.
Common mistakes
Assuming every Shale Outcrop contains Diamond: gather multiple outcrops and accept other mineral drops.
Taking a Seatruck into the mine: leave it outside and swim through the entrance.
Pushing farther into tunnels with little oxygen: turn back while the route remains safe to retrace.
When to stop or switch
End the run when oxygen or carrying capacity is low; return for deeper resources after your vehicle and depth access are ready.
