Iron ore is a mineral substance that generates metallic iron (Fe) when heated with a reductant. Iron ore generally comprises iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Hematite is widely considered one of the most important iron ores due to its high-grade concentrate of iron and its abundance.

Gold ore generates in veins of 4-8 blocks (sometimes up to 16 if two veins happen to spawn together, and as few as 1 if the block that was supposed to be gold ore is occupied by a generated structure). It only appears in the bottom 32 layers of the world. From levels 2-29, the occurrence of gold ore is at 0.1437% (about five times as rare as iron).
