Gold is a fairly rare spawn in all of the stones it spawns in. Most stones that spawn with gold ore has a fairly low chance of dropping the ore, with the exception of Schist.
Gold sells for the most out of all Metals, selling for 93₭ per slab to Chamal. It is also a fancy metal, therefore selling a lot when trading to others or for decoration use in buildings. Its efficiency in tools is the same as Aluminium.
