Many mods allow you to add new ores or stones. Excavated Variants Mod (1.19.2, 1.18.2) adds new ores to each combination of ores and stone variants. Excavated Variants also attempts to create world gens for these ore varieties. Variants can be added to the config file. Some mods are already built into the default configuration, while others will need to be added manually. For examples of ores generated, see the Images tab on Curseforge.
