I tried to mine different things.. Gold seem to be bugged.. out of 11 rocks one drops about 4 units.. platinum sucks for about the same reason.. Tau-23 Niobium also very low on drop and chance of a drop compared to the distance and sell price. Best thing would is to make the $/Time somewhat equal to one another in the mining fields.. because its like always created a "One route" where all the traders and pirate hang out.
To all those who say "My new place makes me more" i can bet you are wrong.. the only thing it might be better at is lack of pirates.
