    I better clarify and say that there has been refinements in XRF hand held instruments technology of the last few years that you can detect and test more reliably now more than 27 of the minerals in the previous link.  You can now detect gold as well, a range of the rare earths and others, but ultimately assaying has the ultimate say on grade as XRF instruments do have flaws (2nd link below).
