Portable XRF (pXRF) geochemistry results have extended previously defined high-grade copper mineralisation and aided the interpretation of structural controls. The pXRF programme forms part of a wider suite of geochemical surveys designed to confirm and extend the known mineralisation of this significant copper porphyry discovery.
EMU Non-Executive Chairman Peter Thomas commented,
“The initial pXRF results from the field are highly encouraging with broad disseminated copper mineralisation reported from the discovery zone potentially providing EMU with an immediate drill target. Whilst geophysics planned over the next few months will tighten drilling vectors, we are optimistic the results support our interpretation that Fiery Creek could host a large bulk multi- million tonne copper – silver porphyry system.
The pXRF survey was designed to extend our previous laboratory analysed geochemistry surveys results. The advantage of pXRF is that it gives immediate feedback in field which can substantially reduce on ground cost and time. The confirmation of significant copper mineralisation in the discovery zone by pXRF is only bettered by the fact that pXRF results from termite mounds in the adjacent zones suggest an even broader envelope of copper mineralisation than first thought.”
