Well I found a pristine Ice ring with a void opal hotspot. Never been VO mining before so I thought I'd give it a go with a friend.
There were very few cores. In 1hr 30 we found 25 cores between us only 5 of which were VO, 1 Grandideitrite, 1 LTD, the other 18 were Bromellite.
On balance we would have earned way more back in the system we were in before on a common reserves ring looking for Serendibite. At least every core in a metallic ring is valuable.
I'm not sure about pristine rings vs other resource states, doesn't seem to make any difference and the VO hotspot was actually nothing of the sort. In my experience you get more of the hotspot material, on average 2x more than all other cores combined, but last night it was the opposite.
