Where to find lithium in Subnautica 2: The ultimate guide

You're probably staring at your screen, wondering where to find lithium in Subnautica 2. I get it. The game doesn't exactly hand you a map with big red X marks. It's frustrating when you need that new air tank but can't find the stuff to build it.

I spent way too many hours swimming in circles just to grab a few chunks of this metal. It's a pain. But honestly, once you know where to look, it's not that bad. You just need to know the right spots.

Let's save you some time. I've mapped out the best routes so you aren't stuck drowning in the deep. Grab your gear and let's get to work.

Why this mineral is a total game changer

You need lithium for plasteel ingots. Without them, you're stuck with a tiny oxygen tank. That means you can't go deep. You can't explore the cool stuff. You're basically trapped near the surface.

Early on, you might think you can just find it anywhere. That's a trap. The game hides it behind heat barriers. You won't see it until you reach warmer waters. You also need specific gear to safely grab the big deposits.

Think of it as a gatekeeper. It keeps you from rushing the late game. Once you unlock the right mutations, the whole ocean opens up. But until then, you have to play by the rules.

Tracking down the best lithium veins

Most of your lithium sits near the Tadpole Pens. Head about 300 meters east of your Lifepod. You'll see the terrain change. It gets hot. Watch your heat gauge. You need the Angel Comb mutation from the area near Wander's Blackbox to survive here.

Don't forget your sonic resonator. This is non-negotiable. Lithium doesn't just sit on the floor in small bits. It grows in huge, dense chunks. You can't mine it with your bare hands. You need the tool to break it apart.

Check the rock formations closely. It looks a bit like lead at first glance. But look for the shape. Lead is blocky. Lithium looks like long, thin rectangles stacked together. If you see bright red tips, you've found the right stuff.

There's a secret spot 350 meters south-southwest of the Lifepod. Look for a wreck. Find the giant clam nearby. It's got purple tendons. The lithium is inside that node. It's risky, though.

The clam will try to crush you. Don't get greedy. Grab what you can and swim out fast. It resets after a bit, so you can go back for more if you're brave enough.

If you need a lot fast, go to the cave 550 meters southeast of the Lifepod. It's near the entrance of the Tadpole Pens. It's loaded with deposits at the base of the rocks.

Technical specs for your survival gear

You need to watch your depth. The standard tadpole vehicle implodes at 250 meters. If you dive deeper without upgrades, you're done. Keep an eye on the HUD at all times.

The sonic resonator is your best friend. It's not just for lithium. You'll use it for almost every hard resource in the game. If you don't have it yet, stop looking for lithium and go find the blueprint first.

Always enable your landmark signals in the menu. The game is massive. Without those pings, you will get lost. Trust me, I've been there. Use the signals to navigate back to your base once your inventory is full.

The path ahead for your base

Once you have a steady supply, your base potential explodes. You can start building those deep-sea outposts you've been dreaming about. Plasteel is the backbone of everything high-end.

Don't stop at the air tank. You'll need more for your vehicles and specialized tools. Keep a stash in your lockers. You don't want to run out when you're 400 meters down and starting a new project.

The game gets harder from here. Expect to find more dangerous creatures as you go deeper. Keep your health up and your inventory organized. Good luck out there.

Quick questions answered

Do I need the sonic resonator for every deposit?

No, but you need it for the big ones. The clam node is an exception, but it's dangerous.

What if I don't have the Angel Comb mutation yet?

Stay away from the heat zones. You'll take damage and lose your gear. Focus on the early game missions first.

How do I distinguish lithium from lead?

Look at the shape. Lead is square and chunky. Lithium looks like a cluster of long, thin rectangles.

What happens if the clam closes on me?

You take massive damage and likely die. Always save your game before attempting the clam harvest.

How deep should I go for lithium?

Most spots are around 300 to 600 meters. Make sure your vehicle is upgraded for those depths.
