Ore

Ore is the general material you receive from mining walls in Caves or Mine Holes that contain metals. It must be smelted in an Ore Smelter to extract the usable metal, although it sometimes smelts into Gneiss (which is affected by your skills, see below). Ore is a type of stone, so it can also be used as pavement and to build with.
==How to Acquire==
Ore is obtained by mining in a Cave or Mine Hole built over a metal node.
==Note==
*The chance of the Ore becoming a bar/nugget is calculated at the moment the ore is mined. The following skills increase this chance: Metal Working, Tunneling, Metallurgy, and Deep Artifice. The mining process does not affect the quality of the resultant bar/nugget at all.
*Ore also counts as stone and can be stacked into existing stone stockpiles, so be careful you don't accidentally use it up in recipes or construction.
