Ore

An ore is a type of item that contains minerals of important elements that are excavated through mining. Most ores appear more commonly the deeper a blockhead mines with the exception of coal, which instead becomes rarer. A random ore can be crafted from gravel at the electric sluice. Oil also has most of the attributes of an ore, but as it can also be obtained from crafting and cannot be obtained from the sluice, it is generally not considered one.
