Now I found the an asteroid with an ORE rating of 28. All the rest had 6 or 8. Is it worth setting up a nice factory there?
There are no other ore mines in that sector (Headquarter PTNI or something) and there are at least 3 factories there just gagging for a nice bit of ore!
What is an exceptable ore/silicone rating and are they worth the out lay?

Saw a UFO last night - It tried to put me off capturing a Orinoco.
