Magnetite (Subnautica)

Magnetite is a magnetic Raw Material that can be found in the Mountains biome, inside the caves there as well as a location at the edge of the Koosh zone nearby. Due to new build updates near the end of 2015, this raw material can no longer be found inside the snake mushrooms in the Jelly Shroom Caves during survival mode game-play, however it may still be found there in creative mode. The Magnetite appears as a reddish brown stone with bright blue spots that are vaguely luminescent.

Magnetite was scheduled to be moved out of the snake mushrooms in the following reference.
