Tritium Mining

I am finally taking my FC into the black along a path I setup on Spansh to go from Sol to Colonia. Looking at the path it gives me, I see that almost every other system is listed as having Pristine rings which I am assuming is for Icy Rings in those systems. I’m about 4,000 Ly out so far and found a Gas Giant with rings that have very large Tritium Hot Spots in it. Being in these HS’s, the Tritium seems to be very low in quantity/quality. Should I just be looking for Tritium in Icy Planet rings or what? Just hit 1800 hours and finally feel like I am wanting to get deeper into the core mechanics. Are there any apps I can use or websites? I use Exploration Buddy already and not opposed to others.
