Lithium Node is a 矿石 resource node in Subnautica 2. It carries 2 drop entries and yields roughly 1.33 items per break when destroyed. Each row in the drop table above is an independent roll, so a single break can produce multiple stacks of different items at the listed chances.
Ore deposits are mineable nodes scattered across the seafloor. Hit one with the Resonator (or any mining-class tool) until it shatters and releases its fixed drop. Ore drops snap into inventory automatically within a few metres, so you can break a row of deposits and keep moving.
