toecutter, I have few questions:
  1. What is minimum of minerals richness of asteroid;
  2. How much asteroids from 20 scanned have minimal minerals richness;
  3. What does 'mining power' means.

'minimal richness' I mean there are different asteroid richness. 87, 2450. Sure from first I mine less ore, but what is 'minimal range'? from 50 to 100 minimal? 200-700 middle? 1k++ high?

Example: richness = 100, composition = copper, argentum, orichalcum, mining power = 25. How much copper I may have?
