Excavator mineral veins

Pick a biome to see which veins the Excavator can find there and how likely each one is, or search for an ore to find the veins that yield it.

How veins work

Veins are placed when the world generates. Each one gets a mineral type drawn by weight from the types allowed in its biome, so the chance column is the share of veins in that biome of each type. Every block the Excavator digs from a vein is either a spoil (at the vein's fail chance) or one of its ores, picked by the ore's share. Use a Core Sample Drill to find out which vein lies under a chunk before you build.
