Can MTH please supply some information on the mineralogy of the East Arunta drilling. The malachite - azurite described in the surface sampling is most likely the result of erosional surface enrichment. Now under this zone of surface enrichment there will be a zone of copper zinc depletion in the partially oxidized zone. Well below that depth we would expect to see non-depleted sulfide mineralization.
My question is: "How deep does the zone of depletion extend here?" MTH needs to determine if the anomalous grades in the drilling were still in weathering-depleted mineralization.
- just basic "geology weathering" 101.
