Cross post from the Rift thread as I thought it might be useful for commanders here while you're farming barnacles for MAs for the CG. It gives you something less mindless to focus on while you're grabbing pods too.
-----
It's a quick guide on where to get jumponium, mainly from barnacle farming. Looking at the hints coming through from FD we may be doing a fair bit of long distance travel soon.
-----
Merope 5C barnacles yield Yttrium, Arsenic and Germanium
Pleiades sector JC-U B3-2 1 barnacles yield chromium, niobium and vanadium
Pleiades sector JC-U B3-2 2 barnacles yield Niobium, Germanium and cadmium
Pleione 11A barnacles yield Yttrium Arsenic and Germanium
Pleiades Sector IH-V C2-16 C4 barnacles yield chromium, nickel and niobium
**EDIT Pleiades Sector IH-V C2-16 Planet D3 now has confirmed barnacles and they yield Polonium**
---
I then go to Heilelang 3 and scour the surface rocks for polonium (EDIT - Polonium bearing barnacles now listed above instead. I've left this in for people that don't want to farm barnies). It also yields niobium, germanium and vanadium there. Great planet that isn't low gravity so they don't fly off all over the place. Find a flat area and search around for metallic meteorites for best results (two lines on the lower part of the radar). the rocks that are a single line on the bottom of the radar can give some rare minerals too. I tend to land at 8.59, 15.24 and then drive back and to towards 8.59, 15.26 which was suggested by another commander a while back on reddit (username non_idea). Nice flat area where you seem to find a few groups of three metallic meteorites fairly frequently.
Merope 1A is good for Zinc and cadmium (Zinc, nickel, chromium and vanadium are needed for basic AFM refills)
---
Basic AFM refill = 2 nickel, 2 zinc, 2 chromium and 3 vanadium
Basic SRV refuel = 1 sulphur and 1 phosphorous
Basic SRV repair = 2 iron, 1 nickel
Jumponium 25% boost = 2 vanadium and 1 germanium
Jumponium 50% boost = 1 vanadium, 1 germanium, 2 cadmium and 1 niobium
Jumponium 100% boost = 3 niobium, 1 arsenic, 1 yttrium and 1 polomium

Be prepared and travel with plenty of the minerals you need and throw away the junk that you'll probably never use.
My final cargo of materials before I leave for the Rift will be:
4 iron
6 nickel
4 zinc
2 sulphur
2 phosphorous
4 chromium
112 vanadium
58 germanium
20 cadmium
13 arsenic
49 niobium
13 yttrium
13 polonium
--
Gives me:
48 x 25% FSD boosts
10 x 50% FSD boosts
13 x 100% FSD boosts
2 x SRV basic refuels
2 x SRV basic repairs
2 x AFM basic refills
Happy shopping/barnacle farming (bear in mind we may get in trouble later on for treating these poor things like cattle)

For barnacle friendly jumponium farming try:
---
Heilelang 2 (try around 0.3729, -75.6871, courtesy of the commander who mentioned Heilelang as a good source for jumponium on reddit previously, username non_idea) is a good source of yttrium.
Heilelang 3 (8.5923, 15.2435) has plenty of polonium, niobium, vanadium and germanium.
Merope 1A is good for Cadmium and Zinc.
Shinrarta Dezhra 1 (28.9126, -36.7043) gives arsenic, niobium and polonium but isn't a nice higher G world which makes collecting the minerals easier.
