All I have is Copper, Silver and Aluminum.
No iron bearing mineral whatsoever, not even any flux stone or anything :/
Atleast I have allot of obsidian.
My first fort ever was in a huge mountain of rock salt. I looked all over for other minerals, but just salt. I gave up on that fort, mainly because I couldn't tell the difference between a construction site and a finished building (I thought finished workshops would look more complete, you know. Some big brown █ for walls and a little door in the front. It didn't occur to me until after I abandoned the fort that the jumble of blue-green and white slashes was my workshop), but also because all I could find was rock salt.
You'd think that building an outdoor workshop out of rock salt would be a bad idea, with it being soluble in rain water and everything, but the dwarves seem to be able to build anything out of everything and completely throw any common sense out the window. I also read on the wiki about possessed people grabbing items out of order and making absolutely handicapped things like Moss agate coffers (which, according to my research, would be a storage box carved out of an unreasonably huge gem stone).
I need to try and teach myself to play, it sounds awesome but I feel the same way I did when I first installed Quark and decided to make an interior- hopelessly lost, except even more than I did with Quark (it had friendly little buttons with tool tips).
