Ores are primary crafting materials necessary for game progress. They usually must be crafted into bars at a Furnace, after which they can craft several essential tools, weapons, armor, and other items. Some items require raw ores themselves, most commonly potions. Raw ores can also be used as plain blocks for construction.
The Calamity Mod adds 12 new ore blocks to the game, that are used to craft a variety of tools, weapons, and armor. With the exception of Sea Prism, Disenchanted Aerialite Ore, Infernal Suevite, and Scoria Ore, which are generated upon world creation, all ores are spawned upon the defeat of specific bosses.

- All ores (excluding Auric) have corresponding enemies (usually Slimes) which drop their respective ore, in order to make the amount obtainable unlimited.
- Prism Shards grow naturally in the Sunken Sea and are dropped by Prism-Backs after the Desert Scourge has been defeated as well as Blinded Anglers, which can be used to craft Sea Prisms.
- Instead of a slime, Scoria Ore is dropped by Devil Fish and Chaotic Puffers in the Abyss after the Golem has been defeated, and Exodium Cluster is dropped by Shockstorm Shuttles in the Space after the Moon Lord has been defeated.
- Instead of having slimes, Auric Ore can be found in Titanium Crates after Yharon, Dragon of Rebirth has been defeated.
