Just in case anyone hasn't done it yet, after completing the Alien quest line in Masteria, Icebyrd Slim gives you a quest to kill 300 drills and rewards you with a B Ranked nebulite, so there's a starting point, it also appears to be repeatable.
Also, since Nexon didn't announce it, I doubt you can get S Ranked stuff, yet.
