The Mine is a buildable module in Achikaps, it is one of the basic modules that have to be built in the game.
The factory is created with 5 metals and has to be near a refinery. It needs units to work (the more units there is, more products can be mined at a time) but doesn't need any material resource. It brings the material corresponding to the type of the using refinery. The blue type (the common one) gives metals and the white type (the rare one) gives bones.
