It's identical to the vanilla Pertam for it's ore definitions and mappings.
Hopping into a quick test world using the Star System start and only this mod I see the ores generated as expected on Pertam.

That said, I have sometimes encountered situations in testing where a planet's ores vanished after the planet was modified. I'm not sure what the cause for that was though. You might want to try pasting in a new planet using creative tools and see if it has the same issue.

ya know... i've been scouring this planet for 3 or 4 days now and I think you may have messed up the ore table in the sbc file... i have yet to find a single gram of any ore and the tables look very odd: "... TargetColor="#000000" ColorInfluence="200" ..." tells me target color is black, yet there is no black in your mats files... - of course i could be wrong and the magnetosphere of the planet is hindering ore detection...
