Can't Find Lithium in Subnautica
Lithium is found as loose material and in Shale Outcrops, so searching only one resource-node type can make it seem absent. Use the early Deep Sparse Reef route before relying on deeper deposits.
LAST CHECK
ANSWER LOCK // QUICK RESPONSE
Search Shale Outcrops and loose Lithium in the Deep Sparse Reef, especially around the area near Officer Keen's lifepod. Later biomes also contain large Lithium deposits.
