Crown MinerBuildings
Buildings do not mine on their own, they multiply what the drill produces. Every level of any building adds +20% mining speed, and the levels of all four add up into one multiplier.
Building multiplier = 1 + 20% × (sum of all building levels)
The cap is 10 levels per building. All four at maximum give
+800% speed, so mining grows 9x. Fully upgrading every building costs
82 500 CROWN.

Prices per level
The level cost grows linearly: base price × level number. Each building has its own base price.

How the warehouse differs
The warehouse gives more than speed: it also sets how much ore and gold you can hold, and each of its levels doubles the capacity. Details are in the Warehouse section.
