My technique is to set everything except painite to the ignore list. I send a prospector off to investigate anything that looks remotely glowing. While it travels to the rock, I multitask and use my mining lasers to chip sample off as many rocks as possible (the ones that are not glowing and are not too uneven and spinny), usually taking off a single chunk as I fly past. If my collectors react, I know that there is painite in the rock, so I launch a prospector. At least 50% of my profit comes from this. Finding a core is a great bonus but not essential. I actually found a rock that had 50% painite surface fragments, 2 painite subsurface deposits and a painite core. It netted me 25 tonnes.
Painite all the way for me![]()
That is an innovative way to use limpets as pre-scanners
