My friend tried mining in a Hauler, while I provided escort. Just watching him chip away and not find anything worth refining for around three hours in different pristine areas, turned mining off for me. It's something people like, sure, just not my thing.
But I guess the Cutter could be viable for it. Big cargo capacity for large hauls and carrying tons of limpets, you can get a pretty high end Refinery, Prospector Limpets and the ones that bring the fragments to you.
Experiment. Tell us your findings.
Never mine in a res site. Find the right ring and just fly at it until you get dropped in. If you stay away from the res sites no npc spawn
You'll never find any good materials this way. RES's actually increase the amount of really expensive metals and minerals you find. Hence the "Resource Extraction Site" name. Part of the whole risk/reward thing.
There's a certain distance you can go after you drop into an RES where NPCs won't spawn but you'll still get the "I'm in a RES" bonus, but I forget the magic number...
