What value must be changed in the "bno-common" file for ores such as copper, lead, tin, and aluminum to be generated?

If you scroll down you will find this line: "[ore_generation.world_generation]".
Under this, you will see all the ores names for example like this: "nickel = false" "coal = true" "diamond = true"
If you want the ore to spawn change it to true, if you do not want it to spawn make it false.
Sorry for my bad english, I hope could help.
