Hmm ye they seem to have some good width and depth, PPM is ok some results are fantastic.
Personally for Co not that excited by it. One major reason is that only 5% of the XRF readings were actually tested to see if calibrations on machines were correct.
Personally I do not think you can justify an XRF reading with such a small sample being assayed to check calibrations.
What I will say is that the XRF machines do find anomalies, so there is def an anomaly there, just how accurate are the readings, well you cant actually gauge it from the data presented
