Minecraft wiki entry for Nether_Wastes, associated text: In Bedrock Edition, if the Nether Wastes is used as the biome for Overworld generation, although the terrain is entirely netherrack, no ore is generated (including nether quartz, nether gold ore, ancient debris, etc.). Caverns and lakes (with red-colored water) still generate. The player is still able to place water in an Overworld Nether Wastes biome, but trying to sleep in a bed still causes an explosion.
