Is this counting in mining missions as well in your experience? Moving between 3-4 high tech systems made my income increase with 1.5 million credits from missions alone...
No, look here

You will have lower yield than you would otherwise have in a pristine belt. Don't know by what margin tho. HIP 19934 has pristine rings, and the nearest high tech station with high demand for your ore is Diaguandri (60 odd lyrs)
Sounds like you actually mined from the rocky ring instead of the metallic ring

Depending on where you're mining, not all of the ring system will be metallic. If you look at the system information, it should give you some information as to whether there are multiple rings and if the good bits are closer to the planet or further away, and then it's a bit of trial and error. But I can tell you personally from mining several pristine metallic rings this past week (and like you, not dropping into the RES but away from traffic), if you're in the right spot you should be seeing indite, gallite, bertrandite, silver, gold, palladium, painite, platinum and/or osmium. Anything else and you should try to find a different spot.
HIP 16607. You're welcome.
Grand total for all that effort was less than 300k - and only because got just enough osmium to turn in for 200k mission.
it must be more than just dropping in at pristine metallic.
This is exactly what I do as well. Aim for one of the thicker, brighter bands because the rocks seem slightly more packedWhen I drop onto a ring I try to aim for a bright white band within the pristine metallic ring. The rocks seem to more densely packed. Where I mine the RES is in the rocky band so that's no good.
