No Copper
No Copper is a Fabric world generation mod that stops copper ore from generating and converts existing copper into iron counterparts.
What it does
The mod intercepts chunk decoration so that copper ore and deepslate copper ore features are replaced with a configured block type, leaving the world without copper ore while keeping the other ore features intact. A server-side engine called PCKR Engine handles this, and a reload command sweeps loaded chunks to replace any residual copper ores that were already placed.
Crafting recipes convert copper items at a 5:1 ratio into their iron counterparts, so five copper ingots yield one iron ingot and five raw copper yield one raw iron, which keeps mining rewards from being lost. A custom Copper Golem construction rule spawns the vanilla golem from one iron block topped by a carved pumpkin, and requires horizontally adjacent iron blocks so it does not clash with the Iron Golem build.
Installation needs only Fabric, and the mod runs on the server alone. Files exist for 26.1.2 only, and the latest build is 0.1.0, released on 2026-07-21. No Copper is licensed as All rights reserved and is not open source.
Key features
Copper ore replacement
Copper ore and deepslate copper ore are swapped for a configured block during world generation, so new chunks contain no copper ore veins.
Retroactive replacement
A reload command replaces copper ore already placed in loaded server chunks with the configured block.
Copper to iron recipes
Five copper ingots or raw copper can be crafted into one iron ingot or one raw iron, so copper items keep a use.
Custom Copper Golem build
The golem is spawned from one iron block and one carved pumpkin, with horizontally adjacent iron blocks blocking the pattern.
