Subnautica 2 Magnetite — Best Locations to Farm Magnetite

Subnautica 2 magnetite is a critical mid-game resource used in advanced electronics, thermal power plants, and Scanner Room upgrades. Without magnetite Subnautica 2, you cannot build the Thermal Plant, the Scanner Room range upgrade, or certain vehicle modules. This Subnautica 2 magnetite guide covers where to find magnetite in every biome, the best Subnautica 2 magnetite location for efficient farming, depth requirements for each area, and optimal collection strategies that minimize risk. Knowing the best Subnautica 2 magnetite spots saves you from aimless searching in dangerous deep zones.

Best magnetite farming biomes

The best Subnautica 2 magnetite location is the Jellyshroom Caves. Magnetite appears as large deposits attached to the cave ceiling and walls at depths of 250–500 meters. The Jellyshroom Caves contain approximately 20 magnetite Subnautica 2 deposits, each yielding 2–3 magnetite when mined by hand or 4–6 with the Prawn Suit Drill Arm. The Thermal Spires are the second-best Subnautica 2 magnetite source, with 10–15 deposits near thermal vent bases at 200–350 meters depth. The Deep Zone has 5–8 magnetite Subnautica 2 deposits scattered among the thermal vents at 500+ meters, but the high creature threat makes it less efficient than Jellyshroom Caves. The Grass Plateau has no magnetite Subnautica 2 — a common mistake made by players who search shallow biomes. The Jellyshroom Caves remain the best Subnautica 2 magnetite location throughout Early Access due to their high deposit density and manageable threat level.

Depth requirements and equipment

Accessing Subnautica 2 magnetite in the Jellyshroom Caves requires the Seamoth Depth Module MK1 (500 m crush depth). The cave entrance is located in the central Grass Plateau trench at approximately 200 meters depth, and the cave floor descends to 500 meters. Without the depth module, your Seamoth will crush before you reach the magnetite Subnautica 2 deposits. For hand mining Subnautica 2 magnetite, bring a standard Scanner and at least two spare oxygen tanks — the caves are large and oxygen management is tight. For efficient Subnautica 2 magnetite farming, use the Prawn Suit with Drill Arm. The Prawn Suit allows you to stay underwater indefinitely, mine deposits faster, and survive Serpent Leviathan attacks. The Thermal Spires magnetite Subnautica 2 deposits require only the Seamoth MK1 depth module (500 m), but the Bone Shark population makes it riskier than Jellyshroom for hand mining.

Efficient farming strategy

The most efficient Subnautica 2 magnetite farming strategy uses the Jellyshroom Caves entrance from the Grass Plateau trench. Build a small outpost at the entrance with a Scanner Room equipped with Resource Range Upgrade — this reveals all Subnautica 2 magnetite deposits in the caves on your HUD. The deposits are concentrated along the ceiling of the main chamber, with a secondary cluster near the Serpent Leviathan's patrol area. Clear the main chamber deposits first (safest), then work toward the Serpent's area with a Stasis Rifle ready. A full Subnautica 2 magnetite run through the Jellyshroom Caves yields 40–80 magnetite depending on collection method — enough for all thermal plant builds, Scanner Room upgrades, and vehicle modules through the end of Early Access. Subnautica 2 magnetite deposits respawn after approximately 3 in-game hours, making the caves a renewable source for ongoing base expansion. If you need magnetite Subnautica 2 urgently and cannot access Jellyshroom Caves yet, the Thermal Spires provide enough for early thermal power needs with careful Bone Shark avoidance.
