I'm on HIP 36601 and there is an interesting fact:
All the Geological signals I get in Horizon don't show in v2.0, it might be because I'm new to the 2.0 interface but those signals are replaced by other non-material relevant, like distress calls etc, on the same planet.
Playing Horizon (NOT 2.0).
Here is the list of sites I visit regularly and know for sure to be rich in raw materials:
HIP 36601 - C 1 a - Polonium XXX
HIP 36601 - C 1 d - Ruthenium XXX
HIP 36601 - C 3 b - Tellurium XXX
HIP 36601 - C 5 a - Technetium XXX
LHS 417 9 E A Geo Sources 18, 19, 21, 23, 25 - Selenium
So I'm gonna top up my inventory with Polonium, Ruthenium, Tellurium and Technetium here and aim for LHS 417 9 E for Selenium, then exchange the grade 4s for all the material I need to feed the Corvette weaponry with Standard ammo, be cause the only two reliable ways for me to make credit are bounty hunting and trade loops...
Now I'm uninstalling v2.0, (trying)...
Update: Planet C5A. Technetium "trees", you shoot branches off them, they only contain the material you're looking for, time to top up an inventory from zero <> 45mn, there are other growth showing on rocks with lower grade raw materials.
