Stardew Valley The Mines Database
The Mines records for Spring 5 access, 120-floor elevator progression, floor sections, reward floors, ladders, infested floors, ores, geodes, dirt patches, Skull Key, Shrine of Challenge, and dangerous mines.
Spring 5 Unlock
Access / Landslide removal, Mountain entrance, and Rusty Sword
The Mines are blocked by debris until Spring 5 Year 1, when the entrance in the Mountains opens. The first visit introduces Marlon and gives the Rusty Sword, turning mining into a combined ore, combat, and elevator route.
Elevator Progress
Progression / Five-floor checkpoints and daily mine targets
The mine elevator saves progress every 5 floors that have been reached. Plan days around 5-floor pushes, then return to the deepest saved elevator stop instead of restarting from floor 1.
Floor Biomes
Floors / Earth, frozen, and lava sections
The 120 mine floors are divided into three 40-floor sections: brown earth, frozen, and lava. Each section changes ore, gems, monsters, visibility, and route pressure.
Reward Floors
Rewards / Multiples of 10 and remixed mine reward planning
Most floors that are multiples of 10 are reward floors with a chest and no enemies. Floor 30 has no reward, while key milestones such as 40, 80, 90, 100, 110, and 120 shape combat and progression.
Ladders and Infested Floors
Traversal / Rock ladders, monster ladders, swarms, and Staircase skips
Each floor needs a ladder revealed by breaking rocks or defeating monsters. Infested and overrun floors require all enemies to be cleared unless a Staircase is used to skip the floor.
Ore and Geode Routing
Resources / Copper, iron, gold, geodes, coal, and dirt patches
Mining routes should target the floor band that matches the resource bottleneck. Dirt patches can add Cave Carrots, clay, artifacts, ore, minerals, and geodes, while Dust Sprite routes help solve coal pressure.
Bottom and Skull Key
Milestone / Floor 120 unlocks Skull Cavern and permanent world changes
Floor 120 grants the Skull Key, opening Skull Cavern in the Desert and Junimo Kart in the Stardrop Saloon. Reaching the bottom also changes monster strength and allows broader gem and rare drop behavior.
Dangerous Mines
Late Game / Danger in the Deep, Shrine of Challenge, and radioactive ore
After Qi's Walnut Room and Danger in the Deep, the Shrine of Challenge on floor 120 can toggle the Mines into dangerous mode. Dangerous Mines add tougher variants and Radioactive Nodes for Radioactive Ore.
