Mineral (StarCraft)

In the computer strategy game Starcraft, minerals are a form of monetary unit that can be used to purchase Starcraft units and buildings. Minerals can be 'harvested' by drones[?], SCVs, or probes[?].

They appear as blue crystalline formations that protrude out of the ground. Being a limited resource, a game can deplete all of the minerals in the level, in which case nearly no new units can be built.
