If you don't use them at all but expired.. I think you can use it. If you had use them, try testing if your eyes feels irritated.

I recommend for eyeliner-users to swab the tips everytime you use it. For health reason anyway, since eye infections is irritating enough and often leads to much serious complications (especially if you use contact lens)

I don't really assured that mineral makeup has anything to do with bacterial growth... Usually this type is too dry for your eyes anyway and will be harder to be removed (usually if you need to drag your skin to remove stubborn makeup... this would lead to wrinkles anyway)
