Iridium is a mineral found along the K/T boundary. Some scientists speculate that iridium is not a native mineral to Earth and is only found here in a thin layer along the surface because of the huge meteor impact that apparently killed off the dinosaurs.

Diamond, titanium, cinnabar, molybdenum, uranium, helium (if you want to count that as a mineral; it does come from underground near Amarillo, Texas)

most probably uranium...because its ore is found very rarely...other one is potash in pure form....normally it is taken out from left over bones and all...but mining for potash is rare...
next is titanium...is found only in sand of some particular beaches...and in far less amount
