On 24 Jan 2018 PEX reported high grade base metal results from Wagga Tank/Wirlong using XRF results(see link to announcement below and extract from the announcement)
The original results from the XRF gave 11m @ 11.7% Zn, 6.5% Pb, 67g/t Ag and 0.3%Cu and the assay results 7 weeks later gave the results I posted in my previous post which were reported as a single interval over 27m rather than two separate intervals over 13m and 11m.
The assays results showed up higher grades than those reported to the ASX previously from XRF but still confirmed the high grade nature of the mineralisation reported with XRF.
So you are in fact the person that is wrong. XRF can and has been used to report grades over continuous drill intervals (in the example above over an 11m drill interval) by people who know what they are doing with these devices and has been used successfully on ASX to report high grade base metal and Ag drill results. Maybe you should take the time to read what I say and learn something.
If PXX had high grade intervals of base metals and an XRF machine they could estimate those grades and report them exactly as PEX has done above.
There are no massive sulphides indicated in any of the cores from the recent drilling. The disseminated bornite is very unlikely to produce high grades. At best it will produce grades of similar tenor to what has already been discovered which will need to be shallow and open pittable to produce results of economic interest.
The core I showed from the Monty deposit in WA had disseminated bornite within other Cu baring massive sulphides so was able to produce very high grade.
With an XFR machine the geologists at PXX should have been able to narrow down the volumetric grade estimations of the observable sulphides or actually give actual grade estimates as PEX have done. The big percentage ranges for the volumetric contents of the various sulphide minerals that PXX has publish in their drill log descriptions only serves to help feed market speculation and nothing else IMO.
The only serious potential for high grade that I have seen is at the base of hole ZX-18020 (which I've estimated) and possibly for high grade gold (given some flecks of visible gold have been observed in some core samples).
