Stage 1; which can be sifted into minerals (from UBC or si02 in the majority), with having drops of 25% for scrushed igneous stone (also includes Obsidian and Hornfel, as well as netherrack), crushed metamorphic stone, crushed sedimentary rock (which includes vanilla sand, sandstone, clay, clay ores on top of UBC's resources) (rare sifts would include mixed minerals, mixed nuggets, they will be far rarer here and more varied considering vanilla stone can theoretically represent any type of stone)

Yes many things go over 100% just like sifted materials it's the same concept

Note all stones become crushed stone, which can be directly sifted

Ore (1%)


Stage 3 Crushed stone ; this is where things like UBC stone, as well as obsidian will start, at a level where respective rocks can be isolated by the minerals they contain, certain stones like limestone or marble have impurites in small amounts and will contain less random resources than something like basalt which can have valuable metals and compounds inside, resources will be isolated into respective types; for example Basalt will give far more olivine than something like granite. While materials will have specific groups associated with them they also can give a mixed crushed ore/ mixed nugget item that needs to be further isolated into it's respective chemical groups

Stage 5; Final Isolation Redstone is a arctype of ore which considers various but, similar materials; Redstone, cinnabar, ruby, Chromite, Uvarovite, jasper, Chalcopyrite, sulfur, pyrite, magnetite, vandium magnetite and Finally Gold) while copper and iron groups might also have pyrite and chalcopyrite as associated with them as well. Ores may have multiple associations as there are many ores of iron, Limonite an ore of iron would therefore be considered in both Iron and Clay ore associations
