How do I install Advanced ore generation?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

What Minecraft version does Advanced ore generation work with?

The listing gives Minecraft 1.21.9, 1.21.10. This is the version stated by the author or source site, not something we verified ourselves.

Advanced ore generation

Java data pack listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Data pack only.

Minecraft 1.21.9–1.21.10Newest
Minecraft 1.21.6–1.21.8

⬇ Download for 1.21.9–1.21.10 ⬇ Download for 1.21.6–1.21.8

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

This datapack changes ore generation to improve the progression in minecraft. Better ores now generate deeper than before and all ores have their specific biome where they generate more abundantly.

Coal : swamp, mangrove swamp
Copper : savanna, dripstone caves
Iron : taiga and old growth taiga
Diamond : ice spikes
Lapis : desert
Gold : mesa and badlands
Redstone : jungle
Emeralds : forest, birch forest, dark forest, pale garden, lush caves

I recommend using the villager trade rebalance experiment with this datapack for best experience. Also try my other datapack, I recommend Rare villages, it pairs well with the trade rebalance experimental features.

This datapack will be updated in the future to help discover this information in the game. For now I will include the ore distribution chart in the file and on the datapack page.

I hope you enjoy this datapack, feedback is always welcome.
