A Metal Mine is a building that produces Metal. Metal is one of the 3 basic resources required by all emerging and established empires for the construction of structures and ships, and researching.

In-Game Description

Metal is the primary resource used in the foundation of your Empire. At greater depths, the mines can produce more output of viable metal for use in the construction of buildings, ships, defense systems, and research. As the mines drill deeper, more energy is required for maximum production. As metal is the most abundant of all resources available, its value is considered to be the lowest of all resources for trading.

Requirements:

• Available from the start

Is Required for:

• N/A

StatisticsEdit

Costs by LevelEdit

(Base Cost is 60 Metal and 15 Crystal)

ProductionEdit

Please keep in mind, that this is only the Metal produced by Metal Mines. There is always a base Metal income of 30 Metal per hour, which should be added to the result of the above formula, to find out total Metal production on your planet.

Additionally production depends on universe acceleration factor.

Production and Profit vs CostEdit

The formula above gives the amount of time in which the total metal production reaches the cost of that level of the metal mine.

The graph above says that, for example, if you built metal mine mine level 12, it will take less than 5 hours to take back your metals which you used to built that level. Metal mine level 12 costs 5189 metal, and produces 1297 metals per hour. Indeed it takes about 4 hours to take you metal back.

Example:

From the graph we observe that if you built metal mine level 30, it will take it 20 days to produce as much as metal you used to built that level.

Metal mine 30 costs 7670042 metals, and it produces 15704 metals per hour. That makes 7670042 / 15704 = 488.41 hours = 20.35 days to produce as much as metal you used to built metal mine level 30.

---

The formula above gives after what hours the profit of upgrading metal mine adds up to catch the cost of upgrading. In other words, upgrading your metal mine will cause an increment in your metal production, if you integrate this increment over time, after some time this integration will be equal to the cost of the upgrading. This formula gives this time period.

The graph above says that, if you upgrade your metal mine from level 13 to level 14, it will take approximately two days to start harvesting your investment.

If we do the calculations with actual data, upgrading from level 13 to level 14 gives 1594 - 1346 = 248 metals/hour. Metal mine level 14 costs 11677 metals. So the time to start making profit is

From the graph above, we observe that if one upgrades his metal mine from level 31 to level 32, he will start to make profit out of it after one year, for level 39 to level 40 it becomes 3000 days!

Note that, all these production and profit calculations are considered only on metal production. We assume that crystal and energy is free. If we were to consider crystal and energy issues, the formula would have been multivariable, the graph would have been 4th dimensional. And also if we considered fusion reactor and solar stallites as energy source it would have been a total mess. So in order to keep things simple, it is only explained on metal production.
