Ratios of sectors to number of mines

[Elrebriwyn]

Apparently I'm missing something here and can't seem to find the answer. My question is what is the ratio of mines you can have for the number of sectors under your control. For instance how many marble and iron mines can I have for 4 controlled sectors and what is the progression from there.

Doesn't work like that.

Sector 1 - Marble (1), Stone (4) - Sector 1's special, as an early mine location apparently shifts from marble to stone, or vice-versa, (can't remember which)
Sector 2 - Copper (3), Gold (3)
Sector 3 - Marble (2), Iron (3)
Sector 4 - Stone (1), Iron (2), Copper (3)
Sector 5 - Marble (2), Stone (3), Iron (2)
Sector 6 - Iron (4), Coal (3)
Sector 7 - Coal (3)
Sector 8 - Iron (5), Marble (5)
Sector 9 - Gold (5)
