I won't be coming with you guys, but I've checked out the Tsakhmet system (Pristine), 11.85 LY from Pallaeni, for materials, in case it helps. There's some useful stuff there if you need to do last minute collection.
Body:
A1 (HMC) Polonium, Molybdenum
A2 (HMC) Niobium
A3 (HMC) Germanium, Tin, Niobium
A5 (HMC) Technitum, Tin
A6 (Icy) Zirconium, Cadmium, Yttrium
A7 (Icy) Technitum
All materials were found in or close to large craters. Mesosiderites and Metallic meteorites only. This was not an extensive survey, and there may be other materials I have missed.
It's an anarchy system with frequent interdictions - so be prepared.
Excelent! I'm parked in that system if anyone wants to do some prospecting tonight
