Ores are almost identical to vanilla Terraria, but instead of disappearing the ores will turn dark and will eventually grow back with new ores, sometimes the ores will even be a different type e.g. copper -> lead.
Ores can be found under Ayeswell (Mining Town) in the Central Mines and Eastern Mines or in Goblin Instance Worlds. Goblin Instance Worlds ores break into shards which will then be changed into ores when you leave the instance world and do not regenerate, unlike their normal world counterparts. Shards are worth half the amount of experience points produced by normal ores.
Mining all ores gives experience points for the mining skill.
Ore Tiers[edit | edit source]
|Demonite/Crimtane||25|| Demonite is unobtainable
Crimtane can only be obtained through Crimson Goblins
As of STW Version 1.12.1a Gold and Platinum is the highest tier of ore that can be found in the worlds, though Crimtane and Obsidian can be found in Goblin Instance Worlds.
