More or less, but they have broader ranges than that. For true accuracy, you can probably find a cheap science book on the internet or in a used book store that will tell you everything you want to know.
Since you're asking about mineral resources, just track down a book on rocks & minerals, maybe on gems. A little Golden Books or some kind of Field guide would do you just fine. They'll often tell you what minerals are found and thus mined together, like certain kinds of quartz are found with gold, diamonds in kimberlite pipes, etc.
For more exotic stuff, you'll have to do a little more research. For instance, nickel-iron can be found in meteor craters- its HARD stuff and relatively pure, and might be very highly valued by miners...but you'll also find peridot in the same strike occasionally. Other meteors strikes can be high in iridium, gold and other precious metals.
