Paul Vidanovich
Paul Vidanovich is a consulting geophysicist and BSc graduate from the University of
Auckland, with 25 years experience in mineral exploration in New Zealand, Australia, North
& South America, and the Asia-Pacific region.
He has worked in many geological settings including epithermal and mesothermal gold,
porphyry gold-copper, massive sulphides, PGM’s, nickel and base metals, mineral sands
and alluvial deposits.
Techniques he has used in exploration include magnetics, IP/Resistivity, radiometrics,
gravity, seismics, ground probing radar, CSAMT and EM. In addition he has been involved
extensively in drilling supervision, drill logging and geological and geochemical
reconnaissance.
In the Coromandel region Paul was involved in the early stages of the Golden Cross mine
study for Cyprus Minerals as well as the Onemana epithermal gold discovery made by
Heritage Gold in 1994. He used similar techniques to those employed at Onemana in
assisting with the discovery of the Favona high-grade epithermal deposit (now owned by
Newmont) at Waihi in 2001.
His recent experience includes working in Australia with the VTEM airborne system in the
search for base metal sulphides, nickel, and uranium. He has also been involved with
design, planning, supervision and interpretation of a number of aeromagnetic/radiometric
surveys in New Zealand.
