Have you guys done any depth testing? On my main mining area on Calypso I noticed that at average search depths of 500-800m I would not find any lysterium at all. Going up to 1000m would increase the amount of Niksarium but replace Blausarium with Lysterium. Also, the gold disappeared in favor of Tereudite. Going shallower on the same spot would yield more Caldorite than Narcansium but the middle depth would replace eronite with narcansium. It's a complete science. I will try a few thousand drops on Monria to see if I can help out.
