Resources

Hey!

I've been playing for a while and things work reasonably well, though the large world is a bit barren.

However, I now researches advanced armor or so and can't find a metal deposit of the type I need anywhere.

Thus, I assume I need to research something else to even know how to find such metals, since

new ressources seem to pop up now and then.

My request thus is: can someone please tell me what resources exist and what prereqs (technologies) have

to be met (researched) to obtain them? This would also be a great thing to add in the Wiki.

Thanks
