[2022] Copper Copper Copper

This image from community member Ba1aB on our Discord shows well where you can find which ore, just keep in mind it's always from the highest natural block on any given position, NOT from sea level: https://cdn.discordapp.com/attachments/448531486313021459/876530423302344744/unknown.png

There is no such command I'm aware of being available to you, but you can send your world to [email protected] to have us check. I can assure you though, that there hasn't been a single world sent in to us so far that did not have any of the ores with a default config. We're always happy to check, though World Generation wasn't touched in last Update.
