Ok, so it seems to me that the Advent have the missionary vessel that lets them be able to mine the metals/crystals pretty easily, but that the Vasari don't have an equivalent ability on their colonizer frigate?  I was trying to figure it out last night and I researched a few techs that seemed related to this ability in the industry section, but I couldn't in the end figure out how to mine/access these resources.

If someone could let me know how to do this I would appreciate it.  It seems like a pretty good advantage the Advent have to be able to do this fairly easily???
