this is a janky system made for a server that i just want to share use something like a viewer to see where they are
ores are mostly found higher up to make strip mines les worth and ballance exploration
iron is in common spawning biomes like forrest and plains coal is where ever it wanted to be diamonds are deep idk redstone is in biome caves and stony peaks gold is in hot biomes zinc from create is supported and found in hot biomes too copper is found in cold biomes emeralds are found in stony peaks lapis is found on stony shores
this shows a cut away for plains biome more ores at surface less lower down note that only andisite is found here
shows a Jei graphic displaying available biomes for the ore zinc in this case and where to find it
(dev build differs slightly) shows gold and zinc in a biome visable high density higher
