The Mines are located in the north area of the Mountains (northeast of the Carpenter's Shop and to the west of the Adventurer's Guild). They are blocked by rock debris until the 5th day of Spring (year 1), when the player receives a letter.
There are a total of 120 floors (sometimes called levels), in the Mines. Ore quality (type) and quantity increases as the player moves deeper into the Mines. The Mines are filled with rocks and dirt patches. Rocks can be mined with a pickaxe in order to obtain stone, ore and geodes. A hoe can be used on dirt patches to collect minerals, artifacts, ore, clay, and cave carrots.
To advance deeper in the Mines, a ladder must be revealed on each floor. The ladder will sometimes appear when rocks are broken or after an enemy is defeated (killing enemies is the stamina-free option to finding ladders). If a floor is "infested" or "overrun" by monsters, all enemies must be defeated on that floor before a ladder will appear.
Passing out from drained health in the Mines causes the player to lose 10% of their gold, as well as various inventory items, including weapons and tools (except for the Galaxy Sword). If tools are lost, they will be returned in the mail on the following day, though Fishing poles and weapons will not be returned. After passing out in the mines, the player will awaken in the mine entrance, found by one of the villagers.
Lost items are recovered by Marlon at the Adventurer's Guild. A single lost item can be purchased there, anytime after passing out due to low health. The cost will be the the base sell price of the item (i.e., the gold that would be obtained from selling the item). Marlon's Item Recovery Service persists until the next time the player loses items in the Mines, when previously lost items are replaced by newly lost items.
A Minecart is located on the entry floor for quick travel to and from the mine. It is unlocked by completing the Community Center boiler room bundles or purchased from the Joja Community Development Form.
The Mines consist of 120 floors (sometimes called levels). These floors are divided into three sections, 40 floors each, with their own themes; the first section has a brown earth theme, the second section has an ice theme, the third and last section has a lava and dark purple theme. The last ten floors of each section has a variation of the main theme; the first section (Floor 31-39) has a shadow theme, the second section (70-79) has a castle theme, and the third section (110-119) has a darker crimson theme.
The corresponding floors in each section have the same layout. For example, Floor 1, 41, and 81 have the same layout; as does 2, 42, and 82; or Floor 10, 50, and 90; and so on.

Every monster killed has a flat 15% chance of spawning a ladder, assuming the enemy was killed over an unobstructed tile. This does not prevent ladders spawning from rocks.
Some floors are preloaded with a ladder (12, 52, 92, treasure floors in skull caverns). These ladders do not prevent ladders spawning from rocks.
After a floor loads, there is a 95% chance that a ladder will try to spawn. A tile is chosen at random, and if it is unobstructed then a ladder is placed. This will prevent ladders spawning from rocks
Every rock hit has a base chance of 2% of spawning a ladder. This is adjusted by daily luck/5 (+/-10% / 5 = +/- 2%) and food buffs (every point of buff/100 i.e. each point of food buff adds 1%). The inverse of the number of rocks remaining after the rock is hit is added (e.g 5 rocks remaining - 1/5 = 0.2 = 20%, 100 rocks remaining = 1/100 = 0.01 = 1%). If no enemies remain then 4% is added. If this chance hits, then a ladder will spawn, and prevent further ladders spawning from rocks. If you are in the skull caverns there is a 20% chance that a shaft will spawn instead, and this does not prevent further ladders/shafts spawning from rocks.
Crates and Barrels
Crates and barrels in the mines drop items when destroyed at the following rates:
|Item||0-39||40-79||80+ (including Skull Cavern)|
The following are the special items that can be obtained from either crates and barrels or monsters carrying special items
|Dwarf Scroll I||0.16%|
|Lost Book/Mixed Seeds||0.16%|
|Dwarvish Helm (Floors 1-40 only)||0.1%|
|Dwarf Scroll II (Floors 1-40 only)||0.1%|
|Dwarf Gadget (Floors 41-80 only)||0.1%|
|Gold Bar (Floors 41-80 only)||0.1%|
|Dwarf Scroll IV (Floors 81-120 only)||0.2%|
|Strange Doll (yellow)||0.03%|
|Strange Doll (green)||0.03%|
|Ore (Floor appropriate)||1.33%|
|Geode (Floor appropriate)||0.51%|
Occasionally you will enter an infested floor filled with slimes or a mix of monsters. Unlike normal floors, there are no rocks and in slime-infested floors the walls and ground are covered in green slime rather than the normal themes. Forage-able items such as quartz or mushrooms may still be found though. To proceed from an infested floor, you must continue to fight until all monsters are killed (this includes duggies that may be hidden under dirt patches), at which point a ladder will appear either where the last monster was killed or next to the entrance (the player will be notified with a message saying, "A way down has appeared").
A Staircase can also be used to escape an infested floor.
An infested floor will always be on the same floor for each day and goes up one floor the next day. For example, if an infested floor is found on floor 54 one day, it will be on 53 the next day, 52 the day after that, and so on. On some days, an infested floor might not be found because certain floors are excluded from being infested. These include elevator/treasure floors and the first five, last ten, and nineteenth floor of each section (refer back to the information about sections in Floors). There can be multiple infested floors at once, each are generally around twenty or more floors apart.
The Mushroom Floor
Sometimes a floor in the lower section of the mine (floors 81-119) will have greatly increased spawns of red and purple mushrooms. These floors will also notably have a variety of colored lanterns which usually includes at least one green lantern.
Note that no mushrooms will spawn on an elevator floor (floors ending in 0 or 5) or if the floor is infested (see previous section.) Additionally, the mushroom floor is neither unique nor guaranteed -- there may be multiple active mushroom floors or no such floors at all on a given day, and that situation may persist for several days or weeks.
Dungeon floors are similar in appearance to the single floor of the Quarry Mine. They may spawn randomly at any floor of the Mines.
The Bottom of the Mines
On floor 120 of the Mines is the Skull Key. The skull key is used to open a door in a cave in The Desert, leading to the Skull Cavern. It is also used to unlock the Junimo Kart arcade machine for play in The Stardrop Saloon.
Furthermore, reaching this floor also changes other parts of the game (introduced in 1.3.27):
- prismatic shards and diamonds will now rarely drop from any monster;
- gems and purple mushrooms may now be found when searching trash bins;
- gems and purple mushrooms may now be requested in NPC quests;
- some monsters will be stronger.
If the screen becomes "misty", "glowy", or "foggy", several of the current floor's flying monsters will spawn and attack. Consuming Oil of Garlic will prevent these infestation fogs.
If the player has reached at least Mining skill level 2, floors can be skipped by using a Staircase (crafted from 99 Stone). A Staircase allows instant access to the next floor in the Mines. After every 5 floors, an elevator will be available, allowing access to that floor at any time.
Shown below are foods with buffs that are useful when exploring the Skull Cavern. Note that eating a food with buffs will wipe out any active buffs and replace them with the buffs from the newly eaten food. If the newly eaten food has no buffs, the existing buffs will remain in effect. Coffee and Triple Shot Espresso are an exception to this rule; they will stack with other food buffs (but not each other).
- The axe, scythe or pickaxe can be used to kill monsters in lieu of the sword.
- Stone can be purchased from the Carpenter's Shop for 20g each during game year 1, making it possible to skip all 120 floors using Staircases for just under 250,000g (useful for unlocking all the floors in order to return later).
- If all monsters on a floor are killed, the chance of finding a ladder under a broken rock is increased by 4%.
- At floor 120, both the Green Serpent Statue and the Purple Serpent Statue are found.
Players with access to their saved game files may find the "Stardew Predictor" utility helpful for predicting which mine floors will be infested and which floors will be mushroom floors. The utility is located at https://mouseypounds.github.io/stardew-predictor/.

- 1.3: Removed exploit that created a ladder to the Skull Cavern on floor 120 by blowing up an item with a bomb.
- 1.4: Added random dungeon (quarry mine) levels. Changed the way mushroom levels are spawned, so they cannot be repeatedly "farmed". Removed exploit where clicking the journal icon would prevent the passing out (from low health) cutscene where items and gold were lost. Mine levels are no longer forgotten when passing out due to low health. Added Marlon's Item Recovery Service. Mine floors now reset as soon as the player leaves the floor, instead of at the next 10-minute tick of the game clock.
