Minecraft wiki entry for Best_biomes_to_play, associated text: Though not ideal for living in, the badlands contain an extra generating rule for gold ore, making it around 3 times more common, and directly at surface level. Mineshafts are also exposed, making them and their loot easier to find. Coal, iron ingots, golden apples, and even diamonds can be found in the mineshafts. Gold can be used to trade with piglins to get most Nether survival items, or to craft golden apples.
