A long as its financially rewarding too. I can get about 3 million on a 2 hour single trip, with a full set of limpets in the conda. It saddens me when I realise I how much I could get on an equivalent trading session, but I just love mining so much! If ice mining pays peanuts however, I can't see me sticking at it. Man cannot live by gorgeous vistas alone....
Oh, and where does the refinery fit in to ice mining? I'm assuming it might be superfluous, so can be dispensed with, and the materials will go straight into the hold?
