Graham Jenke

Senior Consulting Geophysicist

Graham Jenke completed a BSc majoring in geophysics and geology at the University of Adelaide, graduating with First Class Honours in 1972. He has over 25 years’ experience in mineral exploration with major Australian mining companies and the airborne survey contracting industry.

He joined CRA Exploration in 1973, and over the next 13 years was based in Kalgoorlie, Perth, Darwin, Canberra and Adelaide providing geophysical support in exploration programs for nickel, gold, copper, zinc, uranium and diamonds in a wide variety of geological terranes across Australia, Papua New Guinea and New Zealand. He was a core member of the team which discovered the Ellendale lamproite province and the Argyle diamond mine subsequently.

In 1987, he joined the newly formed Kevron Geophysics as manager, and oversaw its emergence as a successful provider of airborne geophysical surveys to the exploration industry.

He returned to mineral exploration with Western Mining in Kalgoorlie in 1989, working on nickel and gold exploration projects and mine sites in the Yilgarn before moving to Perth in 1994 where he became part of the company’s hydrogeological group exploring for water resources, and undertaking site characterisation and environmental monitoring surveys at the company’s mine sites in WA, SA and Queensland. Most recently, he was a key member of a base metal exploration project near Mt Isa and the West Musgrave nickel exploration program.

Graham joined SGC in 2002 and is an active member of SEG, ASEG, EAGE and EEGS.
