Gold ore can be mined from concentrated gold deposits in the Living Rock Caverns. Concentrated gold deposits yield five gold ores at once unlike normal gold rocks. There are four concentrated gold rock spawns, but it is recommended to use the two southern spawns that are closest to the bank deposit which is located in the centre of the cavern.
