Ores are primary crafting materials necessary for game progress. They generally 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 bricks and potions. Raw ores can also be used as plain blocks for construction.

Ores are generally found as veins of placed blocks in the Underground layer and below, and are mined with a pickaxe or drill. Lower-tier ores can be found among Dirt near the surface, or within Floating Islands. Some ores are also dropped by bosses, namely Eye of Cthulhu, Eater of Worlds, Brain of Cthulhu, OcramOld-gen console version3DS version, and Moon LordDesktop, Console, and Mobile versions.

An Extractinator and Wooden Crates (from fishing) also provide ores as random rewards.

A world will generally only contain one ore type from each tier, which is chosen at random, for instance; one world may have Copper and Iron Ores, while another may have Copper and Lead Ores (see tables below). The alternate ore types that do not generate naturally in a world, but can be obtained by other means, such as Crates, bonus dropsDesktop versionConsole VersionMobile version3DS version, Slime drops, or loot from an Extractinator. Hardmode ore types are chosen at random as soon as the player destroys an Altar. There are Desktop, Console, and Mobile versions 21 / Old-gen console version3DS version 20 different types of ores.

The first three tiers of Hardmode ores are spawned by destroying Demon/Crimson Altars, which requires a hammer with 80% hammer power or higher, e.g. the Pwnhammer. Chlorophyte Ore spawns on its own once Hardmode is triggered, though it cannot be mined before killing all of the Mechanical bosses, and Luminite does not occur naturally. Neither ores are affected by destroyed altars. This content is transcluded from Altars.

  1. First altar: Cobalt OreCobalt Ore or Palladium OrePalladium Ore, chosen randomly.
  2. Second altar: Mythril OreMythril Ore or Orichalcum OreOrichalcum Ore, chosen randomly.
  3. Third altar: Adamantite OreAdamantite Ore or Titanium OreTitanium Ore, chosen randomly.

Players will be able to find these new ores scattered across the Underground layer to near-Underworld levels, with them replacing most blocks created during world generation. They will spawn at random locations in varying quantity, in places explored and unexplored alike.

  • Destroying more altars will never spawn Hardmode ore types beyond the three that were randomly assigned to the world during the initial round of destroyed altars. A world with Palladium Ore deposits will never spawn Cobalt Ore deposits, or vice versa. (Except for the Drunk World seed.)
  • Which ores are generated is not determined until the first, second or third altar is smashed. For example, it is not determined if the world has Cobalt or Palladium until the first altar has been smashed. The same goes for Mythril/Orichalcum with the second altar, and Adamantite/Titanium for the third.
  • Subsequent altars destroyed will begin the cycle again, though the fourth to sixth altars will spawn half as much ore as the first ones, the seventh to ninth will spawn only one third of the ore of the first ones, and so forth. So, the nth cycle will only generate one-nth as much ore as the first one. For example, destroying the 19th altar would yield one-seventh of Cobalt/Palladium Ore compared to the first altar. Destroying 12 altars will roughly double the ore provided by the first three; tripling that original allotment would require destroying 33 altars. Notice that although each subsequent destroyed altar will yield less ore, the total amount is unbounded.
  • No matter how many altars are destroyed, ore rarity remains set with Cobalt/Palladium being the most common, followed by Mythril/Orichalcum, then Adamantite/Titanium as the rarest.

Ore generation[edit | edit source]

The amount of ore veins generated upon destroying an altar is determined by the following formula:[1]

\frac{ \left(\mathit{world\ size} \times 310 - \mathit{ore\ tier} \times 85 \right) \times 0.85 }{ \left\lfloor \frac{\mathit{amount\ of\ altars\ destroyed}} {3} \right\rfloor + 1 } \times \mathit{factor}

  • x is the floor function.
  • world size is the width of the world divided by 4200: 1 for small, 1.524 for medium worlds and 2 for large worlds.
  • ore tier represents the respective tier of ore:
Ore type Value
Cobalt OreCobalt Ore Palladium OrePalladium Ore 0
Mythril OreMythril Ore Orichalcum OreOrichalcum Ore 1
Adamantite OreAdamantite Ore Titanium OreTitanium Ore 2
  • factor depends on the ore type, slightly increasing/decreasing the rarity of different types:
Ore type Value
Cobalt OreCobalt Ore 1.05
Mythril OreMythril Ore Adamantite OreAdamantite Ore 1
Palladium OrePalladium Ore 0.945
Orichalcum OreOrichalcum Ore Titanium OreTitanium Ore 0.9
This reveals that worlds with Palladium instead of Cobalt, Orichalcum instead of Mythril, or Titanium instead of Adamantite will, on average, have 10% less of the respective ore.

The table below visualizes this and shows how many ore veins will be spawned for each altar destroyed. If 264 altars were to be destroyed in one world, all following altars would only spawn one ore vein.

Ore type 1 altar 2 altars 3 altars 4 altars 5 altars 6 altars 7 altars 8 altars 9 altars
Cobalt Ore Cobalt 276 veins - - 138 veins - - 92 veins - -
Palladium Ore Palladium 249 veins - - 124 veins - - 83 veins - -
Mythril Ore Mythril - 191 veins - - 95 veins - - 63 veins -
Orichalcum Ore Orichalcum - 172 veins - - 86 veins - - 57 veins -
Adamantite Ore Adamantite - - 119 veins - - 59 veins - - 39 veins
Titanium Ore Titanium - - 107 veins - - 53 veins - - 35 veins

  • These values are for a small world.

All Hardmode ores will avoid spawning in the outer 100 tiles of the world. The highest location for Cobalt and Palladium to spawn is just below the surface, Mythril and Orichalcum start to spawn from the top of the Cavern layer, and Adamantite and Titanium start to spawn in the Cavern layer, lower than Mythril/Orichalcum.[2] All ores stop spawning at 150 tiles above the world's bottom border, i.e. about one fourth into the Underworld.

The amount of altars smashed does not affect the size of ore veins, only the amount. As the generation of each vein is heavily randomized, it is difficult to give exact high and low values from "optimal" veins. Instead, a table of "good luck" vein amounts and "bad luck" vein amounts is shown below. Average yield is likely between 30–40% due to occasional lost ore.

Ore type Good luck Bad luck
Cobalt Ore Cobalt 103 Cobalt Ore (34 Cobalt Bar + 1 Cobalt Ore) 11 Cobalt Ore (3 Cobalt Bar + 2 Cobalt Ore)
Palladium Ore Palladium 103 Palladium Ore (34 Palladium Bar + 1 Palladium Ore) 11 Palladium Ore (3 Palladium Bar + 2 Palladium Ore)
Mythril Ore Mythril 89 Mythril Ore (22 Mythril Bar + 1 Mythril Ore) 11 Mythril Ore (2 Mythril Bar + 3 Mythril Ore)
Orichalcum Ore Orichalcum 89 Orichalcum Ore (22 Orichalcum Bar + 1 Orichalcum Ore) 11 Orichalcum Ore (2 Orichalcum Bar + 3 Orichalcum Ore)
Adamantite Ore Adamantite 58 Adamantite Ore (11 Adamantite Bar + 3 Adamantite Ore) 11 Adamantite Ore (2 Adamantite Bar + 1 Adamantite Ore)
Titanium Ore Titanium 58 Titanium Ore (11 Titanium Bar + 3 Titanium Ore) 11 Titanium Ore (2 Titanium Bar + 1 Titanium Ore)

  • Note that this is not related to the LuckDesktop and Mobile versions mechanic.

Note however, that the above table assumes that all the ore actually replaces blocks. Ore will not spawn if it attempts to spawn over any block not listed below.

In addition to this, Hardmode ores will not generate over Granite Blocks, Marble Blocks, or any hardened sands, and as such cannot be found in the Granite CaveDesktop, Console, and Mobile versions, Marble CaveDesktop, Console, and Mobile versions, and Underground DesertDesktop, Console, and Mobile versions biomes without replaceable blocks already existing there.

Notes[edit | edit source]

  • Meteorite, Obsidian and Luminite aren't considered ores by the game. They don't have "ore" in their names and aren't counted for the Ooo! Shiny! achievement (and Extra Shiny for Luminite).
  • Chlorophyte Ore isn't counted as a Hardmode ore for the Extra Shiny! achievement.

Tips[edit | edit source]

  • Each Hardmode ore is chosen at the moment the first three altars in the world are broken. Ores can be "chosen" by quitting the world without saving (by ending the task or killing the process) after smashing the first altars. It is more easily done with a server, using the exit-nosave command.
    • As of 1.4, using the drunk world seed will generate all six hardmode ores after smashing six altars.
  • All ores except Hellstone and Obsidian are highlighted by the Spelunker buff, making it easy to find veins of ore. Hellstone is not lit up by the buff, but it is by a Dangersense Potion. Obsidian is easily found and made around lava.
  • Using a Crate Potion will improve the chances of obtaining crates and as such the ore-bearing Wooden Crates.
  • Filling in caves with spare natural blocks such as dirt before destroying altars can cause Hardmode ores to spawn in them. They can then also be seen on the minimap, presenting an easy way to convert extra blocks into ores with knowing their exact location.
  • In the 3DS3DS version version, the Palladium Pickaxe and Drill can mine Adamantite and Titanium.
  • Most ores sell for the same as or more than the bars made from them. Prior to 1.4, the exceptions are the late pre-Hardmode ores (Meteorite, Demonite/Crimtane, Hellstone), and Chlorophyte, all of which are far more profitable as bars. (Hellstone and Obsidian are unsaleable as ores, and there is no Obsidian Bar).
    • However, as of 1.4, the sell values of Demonite, Crimtane, and Chlorophyte ores were increased, such that the respective bars sell for as much as their components. Hence, it is more efficient to simply sell the ores.
    • Meteorite and Hellstone remain exceptions, although raw Hellstone can now be sold.
  • Two ways to quickly find Hardmode ores is to use previously discovered Abandoned mine shafts or search along the ceiling of The Underworld. Both of these methods feature large cave systems along a significant horizontal distance, the minecart tracks allow the player to outrun dangerous enemies, and pre-Mechanical boss Hardmode enemies in the Underworld spawn rarely and are easy to avoid.

Trivia[edit | edit source]

  • Old-gen console version3DS version Hellstone's item sprite is a recolor of that of Silver Ore.
  • Hellstone is the only ore that cannot be infinitely generated within a single world. Others can be obtained from sources such as crates, an Extractinator, bosses, duplicable liquids, Meteorite crashes, and mud. Prior to, Chlorophyte was limited by the amount of mud (and dirt) in the world, however with the addition of Dirt Bombs, dirt can be infinitely created, which can be crafted into mud, which can be used to infinitely create chlorophyte.
  • Before the update, Iron and Lead ores did not have bricks.
  • Prior to 1.4, despite being a late-game ore, Chlorophyte Ore only sold for 6 per ore. This could have been because it can be farmed indefinitely, but its bar (and derivative bars) fell right into sequence pricewise.
    • As of 1.4, Chlorophyte Ores now sells for 15 each, which is exactly in line with their bar's value.
  • Luminite sells for the most of any ore, 30 per piece.
  • Palladium, Cobalt, and Titanium are the only Hardmode ores named after real metals.
  • Luminite is the only ore that does not use either a Furnace or Hardmode Forge to craft bars, instead requiring the Ancient Manipulator.
Multiple Tier 1 Ores next to each other on the seed "05162020" (Copper on the left, Tin on the right).
  • As of 1.4, both ores of each tier can be mined in the seed "05162020" that was teased in Red's tweet here. This is just one example of the unusual world generation effects that happen on this seed. A case of this can be seen in the picture to the right. For more oddities like this, see Drunk World.
    • Another oddity is that both evil biomes' ores (Demonite and Crimtane) are spawned.
  • Chlorophyte ore is derived from the word chlorophyll which is a pigment on a leaf. Verify
