Gatherable Materials are Plants and Minerals that spawn randomly throughout Europa's undersea rocks formations. Once gathered, they can be deconstructed into various raw materials for Crafting, or sold to outposts for Marks.
Minerals require a Plasma Cutter to cut them from the rock face. It takes 8 seconds to cut the mineral, after which they can be picked up by hand.
Plants are harvested by hand, and take 1 second to harvest.
