Copper-arsenic ore with a bright turquoise streak. Locked deep enough that you will likely need a Sonic Resonator to break the harder deposits.
Where to Find
Karakorum Metal Farms (deep) and Sparse Plains. Mineable deposits — harder nodes require the Sonic Resonator.
Notes
Used in: Mangalloy Ingot, Ultra High Capacity Air Tank.
Tip: Plan an Atacamite run together with a Troilite run — both live in the deep Karakorum tier and share the same trip.
