Mine

The Mine is a building generates ores in exchange for coins

Description
The Mine is a Building you can place in the game. It takes Coins to produce Ores, Stone, and Element Stone. It produced ores at much faster rate than workers do. In addition, instead of removing the resources when they run out, it replaces them with depleted ores instead. Finally, each non-depleted rock around mine's area of influence gives a small speed bonus (+5%) to a miner. This Bonus can reach up to +775% if the mine is fully surrounded by ores.

= Fast endless mine =

One depleted ore deposit can supply multiple mines just fine. These mines work on 100% speed each. Note that this uses less workers and is faster than a single mine with five workers. A mine with five workers would run on 200% speed. This four-mines-setup can achieve 400% speed. The only downside is the initial building cost.
