Hey 2guys - from the context I can only guess.
"whole rock" is sort of a misnomer, as I understand it what we have at AP is heavily compacted/compressed sediments (whether wind, water, etc deposited). Think sands and gravels layered deep and subject to not just that pressure over time but also desert "cementing" from what there is of water infiltration and evaporation over long periods.
So, we are not talking about an igneous intrusion that might be expected, as rock, to be fairly uniform at least in terms of what species are present if not in their relative percentages throughout the intrusive body. With a sediment layering deposit it depends a lot on what settled out when and where in the process of the transport. So the whole question of what is average, representative sample becomes difficult the more so the larger the area of the claims one is considering. XRF is a field size mobile instrument that can yield gross analyses on what the atomic and to some extent also what molecular content exists in the sample. It works by exposing the sample to X-ray irradiation and spectrographically analyzing the wavelengths re-emitted by the sample subsequent to its capture of the X-rays. I have a friend that was working last year for the USFS based in northern Calif with long service in AZ for same, and they sent him over with a regular half-ton 4x4 pickup last year with an XRF analyzer to follow-up on some tailings spread-fans from 1950's era uranium mining in AZ.
So if there was a recommendation to get an XRF it was probably so that the company could get quick estimates of the chemical composition of any given sample of dirt. Why? Could be a number of reasons. What is the MN content. What is the content of "problem" elements that impact the processing. Etc.
Bottom line is to me, if I want to buy some canned hams for long-term food stockpile, I do not test the 20 pound tins by company X for nitrites, water content, fat, etc. and finding the results acceptible then decide using 5 pound tins from company Y made more sense and so assume the results for the 20 pound tins applied. Even if I did not have to change from company X to Y it would not make sense, but going from one depositional fan layer to another is like changing companies but staying with pig meat.
My 2 cents.
