Civilian mining complex

Description

A Civilian Mining Complex (CMC) is a structure civilians build on mineral rich planets, moons and asteroids if you don't yet have a colony on them.

Each CMC is equivalent to 10 auto-mines using the Empire Mining Production ## Tons technology when it comes to determining extraction rate.

In addition to mining the body that the complex is on, they also function as a level 1 Deep Space Tracking Station and an infinite amount of Mass Drivers. Also, a Garrison Battalion is created, named, and placed on the body upon CMC creation.

Though a CMC will only be placed on an empty body, once a CMC exists another colony may be created by the player and used as a population center, mining base, military depot, etc. This will not prevent expansion of the CMC in the future.

Gathering Wealth and Resources from a Civilian Mining Complex

Civilian Mining Complexes have two settings:

Purchase Mineral Output

Minerals go to Civilian Sector

The settings are found on the Population screen (F2), Civilians / Ind Status tab.

The default settings for Aurora is to have the CMC paying you some royalties. This gives you a small income of 125 units of wealth per year per CMC, regardless of how much minerals are actually being mined out.

Alternatively you can "buy" minerals for 250 units of wealth per year per CMC in which case each mining complex functions like 10 automated mines. This amount is also not dependent on the amount of minerals that are extracted.

If you buy minerals this way, you can to direct the Mass Drivers of the CMC toward one of your colonies where you want to stockiple this minerals input. The colony must have a mass driver of its own to receive minerals, but only 1 mass driver is needed to receive any amount of minerals. Additionally, you can choose not to set a mass driver destination, in which case the minerals will stockpile and can be picked up by a cargo ship.

Civilian Mining Colony Generation

A Civilian Mining Colony will only generate after a number of conditions are met:[1]

1		First, a random number is generated between 1 and 1,000,000. That random number is compared to annual empire wealth generation. If the random number is smaller than the annual empire wealth, the next generation step occurs. Otherwise, no new CMC will be generated that production cycle.
2		Next step is to determine which system a body will be generated in. Each System with more than 10m population is ranked from most population to least. The most populous system has a 50% chance to go on to the next step. If that fails, the next populous system is given a 50% chance, down the line. If all systems fail the chance, the CMC will be generated in the largest population system.
3		Once a system has been chosen, a body must be chosen. First, the body must be surveyed and have no existing colony on it. It needs to orbiting the same star as the selected population, and be no more than 80AU away.
4		On the first run through those bodies that qualify, Aurora checks for deposits of either Sorium or Duranium in excess of 25,000 tons with 0.8 accessibility or greater.
5		If no bodies qualify, Aurora then checks for deposits of either Sorium or Duranium in excess of 15,000 tons with 0.7 accessibility. A tonnage check similar to 4B is performed to evaluate which body gets the CMC.
6		Once either step 4 or 5 find at least one candidate, Aurora finds the total mineral deposits for each body. The deposit size is multiplied by accessibility, ignoring all deposits of 0.4 or less.
7		The world with the greatest total deposit is selected and a CMC of size 1-3 is created on that body

Civilian Mining Colony Expansion

Each production cycle, each existing CMC is checked for expansion. For each CMC, a random number between 1 and 4,000,000 is selected, and if the number is less than annual empire wealth, the CMC expands by 1.

Civilian Mining Colony Closure

When the minerals on the body a CMC is located on are all extracted, a message will generate about the CMC shutting down.

At this point, what will be left is a generic colony, possibly with some minerals stockpiled and a Garrison Battalion. All that is left is to verify that the stockpile is empty, pick up that garrison and abandon the body.
