Mining

Mining is a skill associated with breaking rocks in Stardew Valley.

During the first few days, the mines are closed due to some accident by Joja Corporation. When it is open, mining becomes available to the player. Each level adds +1 efficiency with the class tool (Pickaxe).

Mining skill

Mining Skill is increased by using the pickaxe tool or bombs to break rocks. Each level adds +1 to pickaxe proficiency.

Mining experience is gained from a number of sources. The most common is breaking nodes or stones, but the experience depends on a number of factors such as the professions one has, the location of the stone or node, the type of stone or node, and whether a special items was spawned from the stone. It also might be possible to get mining experience from opening treasure chests in the mine (25 + mine level), although this has not been confirmed in game.

Mining Nodes

Mining is done by breaking apart rocks or nodes with your pickaxe; larger rocks in the outside area or higher tier rocks and nodes in The Mines, the Quarry, and Skull Cavern will take more hits or a stronger pickaxe to break.

Note, the experience levels listed in this table will change depending on your mining professions.

	Amethyst Node	Break apart to obtain Amethyst.	Mines (Layer 7+)	8
	Aquamarine Node	Break apart to obtain Aquamarine.		20
	Copper Node	Break apart to obtain Copper Ore.	Mine (any layer), Quarry	5
	Diamond Node	Break apart to obtain Diamonds.	Mine (Layer 50+)	100
	Emerald Node	Break apart to obtain Emeralds.		80
	Gem Node	Break apart to obtain various Gems.
	Gold Node	Break apart to obtain Gold Ore.	Mine (Layer 80+)	18

Diamonds begin appearing at level 50 in the mines, at approximately 1 in 500 chance of appearing in place of a stone. For every level after level 50, frequency increases by .000016 per level. This makes for a .0028 chance for diamond to appear in place of a stone at floor 100 (1.2 in 500 or 7 in 2500), and ultimately a .003104 chance for diamond to appear in place of a stone at floor 119 (1.552 in 500 or 194 in 62500).
