Resources:Mineral

Minerals are resource objects placed on the ground or in caves that provides mineral material items such as Stone and Iron.
Mineral resources can be mined by getting close to it with equipped a pickaxe.Mineral resource become progressively smaller as mining begins and eventually It's removed from the map and It never regenerate However, mineral resources can be regenerated by repeatedly sealing and releasing the cave (see Cave & Ground Crack article for details).
All minerals have a set hardness, and rarer minerals take longer to mine. A rock with a hardness of 10 can yield 1 degree of mineral in about 5 strikes. The efficiency multiples for each type of pickaxe are listed in Items:Equipment.
==Rock==
Mineral resource producing only stone and pebbles. It can be found throughout the map, although it can be found mostly in Stone Terrain and underground.
	Name 	Area 	Hardness	Product 	Note
	Rock 	All areas	10 	Stone, Pebble	Pebble drops are random (about 1/3)
	Small Rock	All areas	10 	Stone, Pebble	
==Mine==
Mineral resources, including metal ores. Less frequent than the pebbles and rocks described above. Some are found in Stone Terrain and most are found in caves. Most ores can only be used as material after being refined in the "Furnace" of craft furniture.
	Name 	Area 	Hardness	Product 	Note
	Ore Rock 	Stone/Cave	20 	Iron Ore 	At least one appears on a Stone Terrain on the main map
	Copper Rock 	Stone/Cave	16 	Copper Ore 	At least one appears on a Stone Terrain on the main map
	Cassiterite Rock	Stone/Cave	16 	Cassiterite	At least one appears on a Stone Terrain on the main map
	Silver Ore Rock 	Cave 	40 	Silver Ore 	The first cave that was opend by the player must have this
	Gold Ore Rock 	Cave 	50 	Gold Ore 	The second cave that was opend by the player must have this
==Layer==
Resource objects that are not metals or gemstones, but produce useful minerals.
	Name 	Area 	Hardness	Product	Note
	Sandpile 	Desert	10 	Sand 	
	Sandstone Layer	Cave 	12 	Sand 	
	Clay Pile 	Swamp 	10 	Clay 	
	Clay Layer 	Cave 	12 	Clay 	
	Coal Layer 	Cave 	38 	Coal 	The second cave that was opend by the player must have this
	Ice Pillar 	Cave 	20 	Ice 	The second cave that was opend by the player must have this
This object does not melt naturally
==Special Minerals==
Resource objects containing special minerals found mainly in caves. When mined, special minerals drop with a chance.
	Name 	Area 	Hardness	Product 	Drop rate of special minerals	Note
	Limestone Rock Formation 	Stone/Cave 	22 	Limestone 	- 	The first cave that was opend by the player must have this
	Quartz Formation 	Cave 	40 	Quartz 	- 	The first cave that was opend by the player must have this
	Sulfur Rock 	Stone/Cave 	14 	Sulfur, Stone 	70% 	The first cave that was opend by the player must have this
	Fluorite Rock 	Cave 	20 	Fluorite, Stone 	70% 	The second cave that was opend by the player must have this
	Lapis Lazuli Rock Formation	Cave 	30 	Lapis Lazuli, Limestone 	70% 	The second cave that was opend by the player must have this
	Coal&Amber Layer 	Cave 	50 	Amber, Coal 	70% 	The third cave that was opend by the player must have this
	Quartz&Cinnabar Formation 	Cave 	80 	Cinnabar, Quartz 	60% 	The third cave that was opend by the player must have this
	Meteorite 	Ground surface	10 	Iron Ore, Copper Ore, Silver Ore, Gold Ore	- 	Randomly generated by in-game event
One of these is randomly dropped when mining
