Kuba's Minerals
by Kubastic
Kuba's Minerals adds new ores to Minecraft, along with metal blocks and items that have their own uses in crafting and recycling.
What it does
The mod is aimed at expanding the game with ores that have unique purposes rather than serving only as raw material for existing recipes. Right-clicking many of its metal items and blocks over a lava-filled cauldron returns some of the materials used to make them, so older pieces can be recycled into new crafting. Necklaces crafted from emerald, sapphire and ruby give buffs to the player while they are worn.
The mod runs on Fabric for 1.21.4 only, with the latest build BETA-1.03.0 released on 2025-04-29 on the beta channel. Client and server both need it, and it requires Accessories, Fabric API and oωo (owo-lib) to load. The code is under the MIT License and is not open source. It was first published on 2025-04-24 and is one of 1022 world generation mods with Fabric files for 1.21.4.
Key features
New ores
Ores are added to the world with their own processing paths, so they are more than a stepping stone to vanilla materials.
Cauldron recycling
Metal items and blocks can be right-clicked over a lava-filled cauldron to recover part of their materials.
Emerald, sapphire and ruby necklaces
Necklaces crafted from these gems grant buffs to the player while they are worn in the accessory slot.
Invested crafting
Several recipes build on earlier metal and gem items, so progress through the mod adds up over time.

What the author says
Adding armour and tool sets for new ores isn't planned in most (if not all) cases as nobody needs new sets in between the existing ones
