Here's some starting math:
Cost to build Space station 500 kt with 3 Robo Miner I Mineral/Organic/Radioactive

5000 M/300 O/550 R

Maintenance per turn (12.5%):

625 M/37 O/68 R

Production for Miner 1 - 600 Min/Turn (at normal mining ability and 100% mineral content of asteroid/planet) + 600 Org/Turn + 600 Rad/Turn.

Obviously with Increased tech, it becomes Robo II up to 700, 800 per turn.

I am not sure where this discussion is going really, though.
