The best Y levels for priority ores in Minecraft 1.21 are -58 for both Diamond and Redstone, -16 for Gold in normal biomes, and Y 0 for Lapis Lazuli. For upper-level ores, Iron peaks at Y 16 underground and Y 232 in mountain biomes, Coal is most abundant above Y 136, Copper peaks at Y 48, and Emerald generates evenly from Y 224 to 320 in mountain biomes only. In the Nether, Ancient Debris is most common at Y 16, Nether Gold at Y 70, and Nether Quartz at Y 30.
Here are the best levels for all ores in Minecraft 1.21, with all the info you need on their distribution to help you mine efficiently. With over 10 different ores to find and mine in Minecraft, there's a lot of searching that precedes before you can hoard these resources. However, each of these ores has a higher chance of spawning at certain levels or depths on the map.
What Are the Best Y Levels for Every Ore in Minecraft 1.21?
Before we get into the details, here's a complete overview of every ore and its most commonly found levels, alongside its total distribution range:
| Ore | Best Y Level | Full Spawn Range |
|---|---|---|
 Coal | Above Y 136 | Y 0 to 320 |
 Copper | 48 | Y -16 to 112 |
 Iron | 16 (also 232 in mountains) | Y -64 to 320 |
 Lapis Lazuli | 0 | Y -64 to 64 |
 Gold | -16 (above Y 32 in Badlands) | Y -64 to 32 (Y -64 to 256 in Badlands) |
 Redstone | -58 | Y -64 to 16 |
 Diamond | -58 | Y -64 to 16 |
 Emerald | Y 224 to 320 | Y -16 to 320 (mountains only) |
NOTE: As you can see, some ores spawn below Y level 0. Do note that most ore blocks that spawn on Y level 0 and below will be in their deepslate variant. The ores that drop from deepslate blocks are also labeled as deepslate ores.
What Are the Best Y Levels for Overworld Ores in Minecraft?
The eight Overworld ores each peak at different depths, and targeting the right Y level before you start digging makes a measurable difference in how many you find per hour of mining.
Coal (Best: Y 136)
Coal is arguably one of the most common ores you can find in the Minecraft Overworld. The coal ore has a wide spawn range from Y levels 0 to 320, with the most common level being 136. Burnt Forest Biomes, Mountain Biomes, and Caves have the highest chance of spawning this ore.
Copper (Best: Y 48)
Copper is a relatively common ore mostly found at Y level 48, with a spawn range from Y levels -16 to 112. This ore also has a higher spawn chance in the Taiga biome and Dripstone Caves, but none spawn between Y -64 to -17.
Iron (Best: Y 16 and Y 232)
Iron is a really useful ore that spawns between Y levels -64 to 320, with the most common level being Y levels 16 and 232. Moreover, there's a higher chance of them spawning in the Stoney Peaks biome
Lapis Lazuli (Best: Y 0)
Lapis Lazuli has the highest spawn rate at Y level 0 with a total distribution range from Y levels -64 to 64. There's a relatively better chance for Lapis to spawn in Snomy biomes.
Gold (Best: Y -16, above Y 32 in Badlands)
Gold is highly sought-after in Minecraft and spawns across the Y levels -64 to 32. The best level to find it would be Y level -16. However, Gold ore has a higher spawn chance in the Badlands biome, with a spawn range of -64 to 256, and a higher chance at any Y level 32 or above.
Redstone (Best: Y -58)
Redstone is a versatile and useful ore that you can use to create almost anything in Minecraft. With a spawn range of Y levels -64 to 16 and the best distribution at Y level -58. If you want a better chance at finding redstone, the Cave and Jungle biomes are your best bet.
Diamond (Best: Y -58, below Y -30 for Early Game)
Diamond Ore is quite similar to Redstone in terms of distribution. It also has a spawn range of Y levels -64 to 16, with the highest spawn chance at Y level -58. In terms of biomes, you have the highest chance of getting them in the Jungle and Swamp biomes.
TIP: If you are in the early game, the best level to mine Diamonds would be Y -30.
Emerald (Best: Y 224 to 320)
Emerald Ore is essential for trading with NPCs in Minecraft. If you want to find this ore, Y levels -16 to 320 is your best bet. Emerald only generates in mountain biomes and distributes evenly at high altitudes, making the Y 224 to 320 range the best target.
Best level for every ore in the Nether Realm
Now that you know the common levels for all the overworld ores, here are the best levels for all the ores you can find in the Nether Realm in Minecraft:
| Ore | Most common level (in Y level) | Total distribution range |
|---|---|---|
 Nether Quartz | 30 | Y levels 6 to 118 |
 Nether Gold | 70 | Y levels 10 to 114 |
 Ancient Debris | 16 | Y levels 8 to 119 |
Minecraft Ore Distribution FAQ
Minecraft's ore distribution is based on Y-level (vertical height) and is often influenced by specific biomes or generation mechanics. Rarer ores are found deeper underground, while common ores can be found across a broader range of Y-levels. The best ores are usually found deep in the deepslate layers.
Yes, the type of stone block does affect ores and their rarity. Below Y=0, stone is replaced by deepslate, and any ores that generate in this range will appear as their "deepslate" variant.
Deepslate is harder to mine than regular stone, making mining more challenging. Some ores also have reduced "air exposure" rates, meaning they are more likely to generate surrounded by solid blocks rather than exposed in caves.
