Career Summary
John Vann has a background in mining and exploration geology
since 1985 and an extensive track record as a geostatistician
since 1990. He started his mining career with Renison Goldfields
Consolidated (RGC) in 1985 at Renison Bell in Tasmania. He subsequently
worked in the Mining, Exploration and Research Groups of RGC
over an 8 year period, as a Mine Geologist, Exploration Geologist,
Project Geologist, Senior Mine Geologist and Geostatistician.
He completed a Masters degree in geostatistics during his time
with RGC.
In 1993 he joined Geoval, a specialist group of geostatistical
consultants. In 1997 John was appointed General Manager of Geoval,
then with a staff of 8. In 1998 Geoval merged with SRK Consulting
(Australasia) Pty Ltd, where John was appointed as a Technical
Director, and managed SRK's Resource Group.
The specialist consulting company Quantitative Group was
founded in early 2001, with John Vann as a founding director.
Since then he has continued his consulting activities with particular
focus on risk issues in mining, resource reviews, training,
management seminars and strategic consulting.
John's consulting career has spanned many commodities (including iron, coal, base metals, gold, nickel, bauxite, mineral sands, tin...) and has
included work in Australia, South East Asia, Central Asia,
North and South America, Africa and Europe. John was an AIG representative on the Joint Ore Reserves Committee from 1996-2006
(JORC). He currently holds adjunct academic appointments at the University of WA and the University of Adelaide.
In addition to his expertise in mining geostatistics, John also
has a strong reputation for delivering technically up-to-date,
understandable geostatistical training. He has experience of
performing bankable due diligence and various levels of internal
audit for companies and has acted as an expert witness in several
legal cases relating to the mining industry. Since 2006 John has been involved in a series of intensive training programs for mining and exploration management, as faculty of Duke Corporate Education.
