How are mining rates worked out? The manual has
(potential productivity)(mineral concentration) = (actual productivity)
but I just set up a basic game (as Humanoids) and ran it for many turns. Boranium is at concentration 1, I have 1064 mines, but my mining rate is 319kT a year - whereas I thought it'd be 1064*0.01 = i.e. ~10kT
I found an article about how the concentration drop changes as it get's lower, but it didn't mention the actual rate.
EDIT
ARGH - just found something. It's a homeworld so never goes under 30%. Good to know...

As a rough guide, 12500kt per MC point at a mine efficiency of 1, above MC of 27.
For your low min concentrations:
Quote:
Summing up, to approximate the minerals for a concentration change, use the following piece-wise function - ending con >= 27 : 12500 * ln (starting con / ending con)
ending con 26-4 : 462 * (starting con - ending con)
ending con 3, 2 : 1000 each
ending con 1 : 2000.

12500/concentration is the number of kt of minerals that can be extracted before the concentration drops one point. E.g. to go from 50 to 49, you mine 250 kt of minerals (12500/50 = 250). That is for standard, 1.0 mine efficiency. The number of minerals per point of concentration is raised for higher-efficiency planetary mines (1.5 times for 1.5 mine eff, etc). Also, the help does not explain how the lower mineral concentrations are handled. At around concentration 27, the minerals per point "go linear" at ~462 kt. They stay that way down to concentration 4. From 4 to 3, and 3 to 2, there are 1000 kt of minerals in each point. From 2 to 1, there are 2000 kt.
And yes, HWs are a fixed MC of 30

I know my minefields.. but I'm a chaff sweeper.
I used to curse when I got stuck in traffic... till I realised I AM traffic.Report message to a moderator
