Subnautica 2 Metal Farm Guide — How to Unlock, Build & Farm Infinite Resources

What Is the Metal Farm?

Metal Farm — creates mineral deposits over time

The Metal Farm creates mineral deposits over time. Place raw ore inside, wait for the timer, harvest with Sonic Resonator. The ore is not consumed — one piece produces resources indefinitely.

Since Troilite and Atacamite are very rare, this is the only reliable way to get more.

The Bottom Line: Metal Farm — How to Unlock, Build & Farm Infinite Resources — you’re gonna need more of this than you think. I’ve lost count of how many times I’ve had to swim back to a cave because I thought ‘three is enough’ and then needed six more for the next upgrade. Mark the locations on your HUD. Set up a Scanner Station nearby. And if you find a large vein, don’t walk away — come back with the right tool. Your future self will thank you when you’re not hunting for one more piece at 2 AM.
