Gold Mine

The Gold Mine is a building that produces Gold, which is used to construct and upgrade buildings. Upgrading it increases the rate at which Gold is produced, as well as the amount of Gold it can hold.

 * Recoup Time is the time it takes for the investment to pay off. For example, if it costs 4200 gold to upgrade to Lvl 4 and that upgrade only earns you 50 more gold per hour then it will take (4200 / 50 =) 84hrs before that investment becomes profitable. This, as seen above, gets quite inefficient which would on its own make it worthwhile not bothering to upgrade the mines, however having enough mines of a high enough level are also a prerequisite for upgrading your Gold Storage buildings, which are much more important.
