Still nothing from Maia B1BA (or as I like to call it, Palin's Rock). I did find a large mining complex at 0,0 which seems to be a fixed POI. It was quite visible from about 6km up and did not create a blue signature on the radar. Trashed it and the miners there, but all it dropped were uninteresting mining fragments. No Meta-Alloys. Funny thing though, in a crater a few km away I found another mining outpost, a bit smaller.
Could be that the area around 0,0 on Palin's Rock (AKA Maia B1BA) is littered with mining camps. If you're on the theory that meta-alloys are naturally formed in planets and these Ant Hill guys are trying to mine them, could be worth checking out. Notably, that part of the planet is pretty well lit.
As usual, my UA was unimpressed by anything there. Couldnt' discern any difference in its vocalizations.
