Discussion
Of the two holes in the Main Zone which returned significant intersections (Table 3),
one was drilled in a high chargeability zone (KBK0021) and the other in a low
chargeability zone (KBK0020). This must raise a question over the inferred
relationship between chargeability and copper mineralization in this area and suggests
that interpretations based solely on the IP data must be treated with caution.
The principal porphyry target in the Main Zone delineated by Leach (2001) was not
tested by the recent drilling and the mineralization still remains open at depth in the
area near BK09. In order to test this target, holes would need to be sited east and
northeast of BK09 and drilled to the west at -50-60 o .
In the South Zone, KBK0028 appears to have been drilled some 200 metres south of
the main soil geochemistry and IP target described by Geiger et al. (2005)(see fig. 9).
The main target zone therefore remains untested.
Strong clay-pyrite alteration is present in the west zone but the source of copper and
the style of any copper mineralization are not known. Further work could be
undertaken to identify the style(s) of mineralization. This could involve mapping
