1 option:
Get an SRV and a ship with decent range like the Adder, Cobra III, Diamondbacks, Asp, Anaconda. Fit a SRV hanger and buy an SRV for it.
Go to Pleiades Sector OI-T C3-7 and planet B 4 and hit up co-ordinates -19.6535 and -165.4662
Find the barnacle in the ravine, land and get in your SRV.
Target all the "spikes" and shoot them. Collect the materials you want. Return to ship and job done. Sound give you tons of sulphur, zinc, iron, phosphorus, a bit of tin and zinconium iirc as well as some vanadium and very rarely polonium. Probably about 30 pieces of sulphur (10 x3) <- Every bit you pickup is worth 3.
If you want more re-log.
