Edit: HIP 36601 is very good for mining Crystalline Shards. You can find Polonium (G5), and Ruthenium, Tellurium and Technetium (all G4). All at moons around the C star (which is ~150.000 ls from the main star). It's well worth the trip, if you need mats for mat trading, and who doesn't?
Curious - what jump range did you have?
Having trouble plotting a course there with my 28ly range (current, not theoretical max) Keelback. I assume its down to the rabbit warren of permit locked (pressumed Thargoid) systems out that way, but I'd like to be sure!
