Silver Mine

Silver Mine
In the Silver Mine, your workers are scraping precious silver ore which is used to mint silver coins. By upgrading the Silver Mine, your workers can find more silver ore and can mint more silver coins for you to use in buildings and/or troops.
Purpose
The Silver Mine is your key source of silver. It will produce silver coins even when you are offline. Silver is a key resource in many buildings, most troops, and most technologies. The higher the level of the Silver Mine, the more silver produced hourly.
Requirements
You need a Level 1 Timber Camp before you can begin building the Silver Mine.
Building Levels
The maximum level of the Silver Mine is 40. The Silver Mine's appearance changes depending on the level of the Silver Mine.
| Level 1 - 13 | Level 14 - 27 | Level 28 - 40 |

The Silver Mine is great source of silver income (as shown in the below table). However, some things can change the output of the Silver Mine, such as Merchant and the productivity of your island (shown in the next section). Each island produces 10% more of a resource and 10% less of a resource; coming into effect after level 20 (meaning all levels before produce the same amounts of resources). You can find out if your island is +/- by looking at the icon in the middle of your island.
