This is a Rework of Lasercraft32's Ores and Alloys Datapack for 1.21, I have his permission to do it.
All credits of the content of the mod to him, he came up and coded everything, I just ported it from scratch.

-This is not an 100% Accurate Port, Since the original work is a datapack and I made a Mod I had to make it all from scratch, there are some features that I couldn't recreate because the software I'm using (MCreator) Doesn't allow me to make them without super complex code that I don't know how to do.

Main Missing features:
-Fishing Rods
-Bows and Crossbows
-Shields
-Elytras
-Custom Arrows
-Custom Item Frames
