Far from the bubble, there is an intersecting birthplace of tritium, low temperature diamonds, alexandrite, Grandidierite, and some mixed deposits, an fleet carrier is recommended

Double Alexandrite right next to double Benitoite. In a very small area you have a triple overlap

A good place to get Tritium far from the bubble, I mean, just in case. No pirates, a quiet place to mine asateroids.
Eol Prou WI-W b17-2
The ring is absolutely loaded with material spots looking a little bit like cheese with a Double Tritium hotspot and with in 30 LY of Colonia making it perfect for a free fill up with a mining ship for your or others fleet carriers.

Quiet, close to jump arrival point. Chill mining experience. There is one Haz rez available if that is your thing.

Multiple high demand and high sell price materials, no overlaps but there’s little traffic.

Eng: Easy. Outside the bubble. No NPCs. On the Guardian route “Eta Carina Sector EL-Y d16” Ita: Facile. Fuori bolla. No NPC. Sulla rotta Guardian “Eta Carina Sector EL-Y d16”
Guttors
You currently have guttors abc 2 listed as a double rhodplumsite, but it isn’t. Its a double overlap alexandrite.
Swoilz WD-T D3-5
Lots of overlapping materials, notably a 2x Musgravite overlap, a 2x Alexandrite overlap, and a handful of mixed material hotspots as well.
