Okay, here are some resource ideas (Beware: My Galactipedia entries suck, so you may need to adjust accordingly):
Harder than steel and theorized to be the very metal that made up the claws of Wolverine in Marvel's X-man comics, this is considered a much needed improvement in armors and casings for starships. Adamantium is a common material found usually on rocky bodies floating in space, and barren moons.
These are materials only mined in the deep caverns and catacombs of a planetary core. Deep within, the extremes heating gives this material a profound energy, which makes it useful in engines running at speeds faster than warp speed. With this new material, our efforts at reaching speeds beyond measure are nearly unmatched. These core fragments are also useful in prcoesses for reactors and sometimes shieldings, as well. They are very hard to grab, and only planets with a very hot and active core, such as volcanic planets, will have the high-powered fragments needed for use in starships.
A bright, purple, highly valuable, and presumably radioactive element that proves very useful in the making of railguns and missiles. Also useful in the making of certain high-tech armors. Can be found commonly on barren moons and ice worlds. Sometimes (though rarely), on Marshy Swamps and Continental worlds too.
A black material used to exercise the use of mind control. In the presence of malignite, which is found in abundance on very high mountainous locations throughout the galaxy, (sometimes deep underground too), control of sentient subjects is completely effective in almost one hundred percent of cases. It should be in our best interested to find this rare material in place them in every starship available so we may one day take over the galaxy.
The very material said to power the mythical Earth city of Alantis, this material proved very useful in the making of advanced gravitic weapons, and machines used to control time and space. We must take care when mining this though, as it highly radioactive and unstable. As of right now, we've only been able to find them on icy worlds, and even then, in only small quantities.
Said to be discovered by Dr. Janos Rukh in 1936, this material is useful in the creations of powerful death beams as use of destructive mass terror. Its also theroized to have strange healing powers. If so, then it would be very useful in the making of advanced medbays. So far, even though Dr. Janos claims to have discovered it, there has been no sightings of it, even in the most resourceful locations of space.
That's all I have so far, I may have more suggestions later. Hope this expands your imagination a bit :). Took these ideas from some of my favorite sci-fi movies.
EDIT: Oh lurchi, another idea for you. Hemp (or some sci-fi variant of it). Yes, we need more pot-heads in space. I'm quite sure the Shandar or Securans do these things in their spare-time Or if anything, come up with some kind of illegal contraband. It think it could be a useful role-play for the space pirates, you know. It'd be great to have that empire that controls the illegal monopoly of rare resources, too. It make this game feel much more like a space opera than it already is, too.
