Tower Incremental metal mining provides the core materials required to purchase stair milestones, clear upgrade trees, and secure permanent rebirth perks in the Roblox simulator by Lucky CStudios. Progression across the tower relies on extracting raw deposits from specialized rooms, beginning with silver on early floors, expanding into iron processing at Floor 10, and scaling into advanced star metal forging near late-game rebirths.
Unlocking the Mine and Early Silver Mining
The first mining area becomes available on Floor 3 and costs 1,500 gold to open. Inside this quarry room, players manually swing a pickaxe or activate the auto-mine toggle to break mineral blocks scattered across the rock face.
Breaking default resource blocks in this chamber yields silver, the game's secondary currency. Early silver generation provides the purchasing power needed to buy foundational upgrades from the mine's internal board and unlock the Floor 5 upgrade tree.
Key early-game mining upgrades available inside the Floor 3 room include:
| Upgrade Name | Cost Resource | Function |
|---|---|---|
| Faster Mining / Pickaxe Speed | Gold / Silver | Increases swinging rate to break ore nodes more quickly. |
| More Silver Per Ore | Silver | Boosts the baseline silver payout gained per broken block. |
| Gold Multiplier | Silver | Converts silver gains into passive income multipliers for standard gold generation. |
Resource nodes in the quarry automatically reset roughly every five minutes, though breaking blocks continuously clears paths to exposed veins deeper in the room.
Iron Ore Extraction and Smeltery Automation
Iron deposits begin generating once players construct stairs up to Floor 10. Reaching this milestone introduces raw iron veins inside the main quarry and unlocks the Smeltery room.
Iron functions differently from silver because raw ore cannot be spent directly on stair building or the upgrade tree. Players must process raw ore into refined ingots:
- Extraction: Mine raw iron veins inside the quarry. Veins spawn alongside silver and yield raw ore when broken with the pickaxe.
- Transportation: Raw ore is carried to the Smeltery or transferred instantly once the "Deposit Iron From Anywhere" upgrade is purchased for 30 million gold.
- Smelting: Ten raw iron ores are loaded onto the conveyor belt and pressed into one refined iron ingot.
Refined ingots are used on Floor 10 and Floor 15 upgrade tree tiers, trail shops, and permanent upgrade chambers. Upgrading the Smeltery increases conveyor belt travel speed (reducing processing delays down to two or three seconds), expands the deposit bin storage capacity, and unlocks bulk smelting to process larger batches simultaneously.
Optimizing Mining Multipliers and Node Density
As stair costs scale into billions and trillions of gold, manual pickaxe swings yield insufficient resources without stacking luck, spawn rates, and ore multipliers. Players can optimize their metal output through several interconnected mechanics:
Mine Purchase Board
The purchase station inside the mine offers gold-funded enhancements that directly alter the block field:
- Ore Density: Increases the spawn concentration of metal nodes across the walls.
- Lucky Strike: Grants a percentage chance for broken nodes to drop double ore yields.
- More Iron Per Ore: Raises the volume of raw iron harvested from an individual vein.
Glyphs and Element Multipliers
Stepping onto glyph boards across the tower rolls passive runic multipliers that drastically scale metal yields:
- Lava and Water Glyphs: Provide baseline luck, gold multipliers, and early silver boosts.
- Poison Glyphs (Floor 15+): Introduce massive iron multipliers that multiply mining drops dozens of times over.
- Wind and Crimson Glyphs: Further stack luck multipliers, making rare glyph tiers and mining bonuses trigger more consistently.
Advanced Metalworking: The Star Forge
Beyond raw silver and iron ingots, late-game progression requires star metal. Unlocked higher in the tower near Rebirth 7 and Rebirth 8, the Star Forge functions as a secondary metallurgical station.
Instead of accepting raw mined ore from pickaxe swings, the Star Forge requires players to deposit stockpiled iron ingots. The forge processes these ingots into star metal, which is required to clear late-tier upgrade trees (such as Upgrade Tree 4 and 5), purchase high-tier movement trails, and satisfy the 5,000 star metal prerequisite for Rebirth 8. Like the Smeltery, the Star Forge offers internal upgrades to expand holding bins and multiply total star metal output per cycle.
Rebirth Impact on Metal Mining
Performing a rebirth resets stair progress and wipes standard inventory reserves, but provides permanent account-wide multipliers to metal production:
- Rebirth 1 (Floor 16 / 1 Billion Gold): Grants a permanent 40x gold boost, 3x silver boost, and 3x iron boost.
- Rebirth 2 (Floor 36 / 1.9 Trillion Gold): Retains floors 1 through 20 and further stacks metal production multipliers.
To prevent restarting metal mining operations from scratch after each prestige, players can spend gold and refined iron ingots in the Permanent Upgrades chambers (located on Floor 20 and higher). Purchasing perks like "Upgrade Board 1 will not reset" or "Section 1 of the upgrade tree will not reset" permanently preserves your mining improvements across subsequent rebirth runs.
Frequently Asked Questions
Where do I find iron in Tower Incremental?
Iron ore does not appear at the start of the game. It begins spawning inside the Floor 3 mine only after you purchase stairs up to Floor 10. Once unlocked, iron veins spawn alongside standard silver blocks.
Why is my iron not showing up in my inventory to spend?
Raw iron mined from veins must be converted into iron ingots before it can be spent on the upgrade tree. Take the raw ore to the Smeltery on Floor 10, where ten pieces of raw ore are processed into one iron ingot.
How do I automate iron deposits?
You can automate iron deposits by purchasing the "Deposit Iron From Anywhere" upgrade inside the Smeltery for 30 million gold. This automatically sends all mined iron ore directly to the smelter conveyor belt without requiring you to walk or teleport to the room.
Do mining upgrades reset when I rebirth?
Standard mine upgrades and unspent metal inventories reset upon rebirth unless you secure permanent upgrade perks. By spending iron ingots in the Permanent Upgrades room on Floor 20, you can lock in specific upgrade boards and tree sections so they persist through future rebirths.
