Copper Caves

Copper Caves are resource-gated cave POIs in the Coastal Jungle biome. The cave system contains copper ore veins and hidden chambers behind destructible rock walls. Copper Caves are marked on the map with a Pickaxe icon and are the player's primary source of Copper Ore before deeper biomes unlock.
Look for the Pickaxe icon on the map.
The entrance is a crack in a stone wall; press E to enter.
The most reliable starting Copper Cave is on the starting island, near the initial camp.

Smash visible copper-veined rock on the entry walls.
Break through plain grey boulders; they hide passages to deeper chambers.
Clear the hidden passages to reach dense ore chambers.
Clean runs can yield 400+ Copper Ore in a single trip per community guides.
Empty your inventory except for pickaxe, lamp, and food before entering. Carry weight is the real limiter.
Drop a Fast Travel Bell near the entrance; respawn cycles keep the cave productive.
Upgrade to Copper Pickaxe or Iron Pickaxe once you have enough ingots.
Caves are pitch-black inside, and the standard preparation list calls for an Oil Lamp or a carried Torch before entering. Players still arrive at the entrance unprepared often enough that a fallback worth memorizing exists: the build menu functions inside the cave, and a placed torch costs only a few units of wood.
Open build, drop a torch, keep mining. Stand inside the dark chamber, open the build menu, select the Torch from the lighting category, and place it against a wall or at the mouth of a side passage. The placed torch stays lit indefinitely, so a single drop usually lights an entire chamber for the rest of the visit. Place a second torch deeper in if a Waste Rock clear opens a previously unseen branch.
Why this matters for full-cave clears. The classic mistake on a cave run is sweeping only the visible front-room veins because the deeper passages look like dead ends in the dark. With placed torches at each junction, the grey boulders along side walls become visible from a distance, and the player is far more likely to clear the cave for the full 400+ ore haul rather than walk out with a partial stack. Always carry an extra five or six wood on a mining trip specifically as torch fuel; the inventory cost is negligible and the lighting upside is the difference between a good run and a great one.
Permanence note. Placed torches persist between visits as long as the cave area is not destroyed by an event. Clearing all the Waste Rocks on the first deep run and lighting the chamber leaves a friendly, navigable space for every respawn cycle afterward. Players who treat a starting-island Copper Cave as a permanent base mining stop benefit twice from the placed-torch habit: first on the initial clear, and again every three in-game days when the deposits respawn and the lit chamber removes the lamp prep entirely.
