Gold Ore is a fairly rare ore found in Minecraft, typically found in veins of 1 to 9, from y=0 to y=31 in all biomes, and in veins of one to nine from y=28 to y=80 within a badlands biome. The ore itself is dropped when mined with an iron pickaxe or better. It has little use in tools and armor, since the durability is very low. Contents 1 Uses
