Raw materials are no longer an issue. If you're still relying on driving around looking for rocks to shoot, you're doing it wrong. Better alternatives:
Geological sites (fumaroles etc). Mats everywhere.
Crashed ships (e.g. Bug Killer). Three cargo racks containing g4 mats, refreshed on logging. Do a few laps, then trade.
Crystalline Shards. All g4 mats except selenium, in abundance. Fill up completely, then trade down to fill up g1 to g3, then go back and fill up g4 again. You could then trade to fill up the entire selenium row and then make a third trip to fill up all other g4's again.
For encoded mats, the trader at Ray Gateway is only 2 or 3 jumps away from Jameson's Cobra.
