Everyone likes shiny things, including our settlers. Since we set up the basics of our heavy industry and have copper for tools and coins, it’s time to expand and build some Silver Mines and Gold Mines.
Both resources are used to produce coins in the Mint. The coins can be used in two ways:
First you can use them to grow your population faster when copper coins are not exciting enough anymore to attract immigrating settlers. While silver will enable you to reach a solid population, gold is always very attractive and allows you to reach the highest amount of settlers total.
Second you can store the coins in specific storages, and those riches will additionally motivate all your soldiers when they are attacking enemy territory, as the coins are their potential reward for defeating the enemies. Of course, shiny gold coins are more attractive than copper coins, while silver is in the middle.
The Silver Mine requires our settlement to be on Town-Level (), which also means that underground mining is available right away. It can be upgraded once.
At Town-Level () three workers are mining Silver on surface or underground deposits.
At City-Level (), a fourth worker joins his colleagues.
When even more rare metals are required, it’s time to build the Gold Mine.
The Gold Mine requires your settlement to be on City-Level (), four workers mine valuable gold from surface and underground deposits.
To discover the underground deposits, we first have to build a Geologist’s Hut and send our Geologist out to look for them. As soon as they found a deposit and marked it with a sign, we can build a mine in the vicinity and start exploiting it.
