Magnetite
Magnetite is a deep-biome mineral in Subnautica 2, used for advanced electronics, sonar modules, and Cyclops upgrades. It unlocks the sonar that lets you navigate pitch-black biomes like the Lost River and the Lava Zones safely.
Quick Info
How to Get & Where to Find
Magnetite spawns as loose ore on the seabed of deep biomes and as large minable deposits. The Prawn Suit Drill Arm is the most efficient collection method, but you can also pick up loose ore by hand early on. Magnetite is dark and slightly metallic, often found near uraninite and lithium deposits.
Lost River
300–500m — the primary Magnetite source, with large deposits along the riverbed.
Primary source — deepJellyshroom Cave
180–250m — loose Magnetite near the cave entrance and around the shrooms.
Earliest accessible sourceMountains Seabed
200–300m — scattered loose ore on the deep slopes.
Predator-heavyUses & Recipes
Magnetite unlocks the sonar system, which is essentially mandatory for navigating the Lost River and deeper zones without crashing into leviathans. The Cyclops shield generator is another key sink, capable of absorbing leviathan attacks during deep expeditions.
Tips & Strategies
Bring the Prawn Suit
Large Magnetite deposits in the Lost River are far more efficient to mine with the Prawn Suit Drill Arm than collecting loose ore by hand. A single deposit can yield 10–15 Magnetite.
Prioritize the Sonar
Cyclops Sonar is the highest-leverage Magnetite sink. The Lost River is pitch black in places, and sonar is the only reliable way to spot ghost leviathans and navigate safely.
Start at the Jellyshroom Cave
The Jellyshroom Cave is the shallowest source of Magnetite. Visit early with a Seamoth to grab loose ore so you can craft the first sonar before committing to deeper expeditions.
Pair with a Power Cell Charger
The shield generator drains Cyclops power fast. Bank extra Magnetite for the module and pair it with a Cyclops power cell charger to keep your shield topped up mid-fight.

Where is Magnetite found?
Magnetite is found in deep biomes like the Lost River, Jellyshroom Cave, and on the seabed of the Mountains. It spawns as both loose ore you can pick up by hand and as large deposits that require the Prawn Suit Drill Arm.
Do I need a Prawn Suit for Magnetite?
Not strictly, but the Prawn Suit Drill Arm makes mining large Magnetite deposits far more efficient than collecting loose ore. Early on, you can hand-gather from the Jellyshroom Cave with a Seamoth for the first sonar module.
What is Magnetite used for?
Magnetite is used for the Cyclops Sonar, Seamoth Sonar, Cyclops Shield Generator, and several advanced electronics recipes. Sonar is the most critical early sink because it lets you navigate deep biomes safely.
How much Magnetite should I collect?
Aim for 12–18 Magnetite to cover the Cyclops Sonar, Seamoth Sonar, and Shield Generator. If you're pushing into the Lava Zones, bank more for advanced recipes like the Thermometer and the Prawn Suit Thermal Reactor.
