Biome Ore Richness
by balbec
Biome Ore Richness changes how ores generate, so the ores a world holds depend on the biome a player digs into.
What it does
Biome Ore Richness is a NeoForge mod for 1.21.1 that alters world generation. Ore veins become richer in some biomes, and the mod can remove vanilla ores from biomes where they are not wanted, so a biome's mineral mix reflects its character. Ore caves can be made more certain to appear depending on the biome they sit in.
The mod is built to work with other mods that change world generation. It reads game tags, so biome and ore settings can be adjusted to suit a pack without editing code. It runs on the client and the server, so the server and every player need it. The code is under the MIT License, but the project is not open source, and the latest NeoForge file, 1.4.0, was published on 2026-06-21.
Key features
Richer ore veins
Selected biomes generate ore veins with more ore, so mining in those regions yields more material.
Biome-based ore caves
Ore caves appear more reliably depending on the biome, giving each region a predictable mineral profile.
Vanilla ore removal
The mod can remove vanilla ores from specific biomes, so those biomes stop producing them.
Tag-driven configuration
World generation changes follow game tags, which lets other mods and modpacks adjust which biomes receive which ores.

Use cases
Modpack economies
Pack authors can tie resource scarcity to biome, so players must travel to find particular materials.
Custom world generation
Servers that already change terrain can add ore behavior that follows their own biome layout.
Who it’s for: Pack builders and server owners on NeoForge 1.21.1 who want ore distribution to vary by biome rather than follow vanilla rules.
How it compares
Ore Sources is also a NeoForge option for 1.21.1, and it is open source under the MIT License. Both sides need it, so players and the server must install it together. Rich Ore Vein targets Fabric and NeoForge across 26.1.2 – 26.3, and it is not open source. Only the server needs it; players can join without installing it. Biome Ore Richness covers only NeoForge 1.21.1 and is not open source.
