Where can I find Copper in Subnautica 2?

Copper is found inside caves. Look for Sandstone Outcrops, Copper Veins, and Large Copper Deposits from the shallows down to about 250m. Small deposits can be picked up by hand.

What is Copper used for in Subnautica 2?

Copper is a core material for electronics and wiring. Direct recipes include Copper Wire (2 Copper at the Fabricator), Basic Battery (2 Copper + 1 Acidic Raion Pouch at the Fabricator), and Beacon (1 Copper + 1 Titanium at the Fabricator).

Do I need a tool to collect Copper?

Small Copper deposits in outcrops and veins can be picked up by hand. Large Copper Deposits require the Sonic Resonator or a vehicle drill arm to harvest.

Where to Find Copper in Subnautica 2

Where to Find Copper

Copper is a raw mineral found inside caves, not on the open seafloor. It comes from Sandstone Outcrops, Copper Veins, and Large Copper Deposits. Copper feeds into early electronics recipes including Copper Wire, Basic Battery, and Beacon.

Quick Facts

Type	Source	Collection	Key Early Use
Raw Resource / Mineral	Sandstone Outcrops, Copper Veins, Large Copper Deposits	Hand pick, Sonic Resonator	Copper Wire (2 Copper)

Copper Sources

Copper is found in cave systems through three source types:

Source	Description
Sandstone Outcrops	Breakable rock formations inside caves; yields Copper when broken
Copper Veins	Ore veins inside caves; pick up directly
Large Copper Deposits	Bulkier mineral deposits deeper in cave systems; requires Sonic Resonator

Copper is found from the shallows down to about 250m. Start with caves you encounter during early exploration.

Mid-game alternative: the Processor can convert Silver (x1) or Titanium (x5) into Copper. Both conversion recipes start locked and become available through progression.

How to Collect

Source	Method	Tool Required
Sandstone Outcrop	Break open by hand	None
Copper Vein	Pick up directly	None
Large Copper Deposit	Break open the deposit	Sonic Resonator

Small deposits in outcrops and veins are accessible from the start with no tool requirement. Large Copper Deposits become accessible once you craft the Sonic Resonator.

Used In

Recipe	Copper Needed	Why It Matters
Copper Wire	2	Required component for the Habitat Builder recipe
Basic Battery	2	Powers the Scanner and Habitat Builder
Beacon	1	Marks locations for return trips

Copper also appears in additional tool and equipment recipes as you progress.

Priority

Copper is worth collecting whenever you enter a cave. The first Copper Wire costs 2 Copper and is required for the Habitat Builder. The first Basic Battery costs another 2 Copper. A good early target is 4-6 Copper to cover both the Copper Wire and first Basic Battery.

Common Blockers

“I cannot break the Large Copper Deposit.” Large deposits need the Sonic Resonator. Craft it first, then return to the deposit.

“I keep finding Titanium instead of Copper.” Titanium comes from Limestone Outcrops. Look for Sandstone Outcrops in caves for Copper instead. Sandstone Outcrops and Limestone Outcrops are different rock types.

Next Action

Collect 2 Copper and craft Copper Wire at the Fabricator for the Habitat Builder recipe. If the Habitat Builder does not appear in your Fabricator, check the Habitat Builder Blueprint page first.
