Vale - Keeva Vozoff

Professor Keeva Vozoff

Missed and remembered fondly by friends, colleagues and students from many parts of the world.
Before coming to Australia in 1972 to take up the appointment of Professor of Geophysics at Macquarie University, Keeva Vozoff was already well known in the geophysical world. By 1958 he was known as the ‘father of 3D EM modeling’, and in 1969, the ‘father of 2D magnetotelluric (MT) inversion’. These milestone achievements were continued at Macquarie University when, in 1975 he became the ‘father’ of ‘Joint Inversion of DC resistivity and MT’ and in 1978, ‘3D MT modeling’. Keeva was born on January 26, 1928 in Minneapolis, Minnesota where he obtained his first degree, in physics, in 1949. Then followed a MSc in Pennsylvania State in 1951 and a PhD at MIT in 1956. During the period from 1951 to 1991, Keeva applied his talents to many positions in private geophysical companies including Geophysical Service Inc. and academically, he was a visiting Assoc. Prof. at the University of Alberta, the University of California (Berkeley) and at the University of Cologne. In 1981, at Macquarie, with his characteristic drive and enthusiasm, he established the Centre for Geophysical Exploration Research (CGER), such an institute being unique in Australia at that time. As well as EM, it dealt with seismic processing and numerical modeling and by hosting visiting post-graduates from many countries, produced outstanding research results. Keeva retained the chair at Macquarie until 1991 and continued to be active in research at the age of 80. All this and more is summarized in the SEG wiki site

Vale - Sir Arvi Parbo

Sir Arvi Parbo - Tributes

A Man of modesty and grace.
The list of Sir Arvi’s achievements before and beyond his executive life is a book in itself. But he was admired for so much more than his success in business. Ask any of the many who knew him and they will identify his modesty and good grace as the surest measures of the man. “He was a great contributor to the development of Australia,” fellow titan of the second half of the 20th century, Don Argus, said on Tuesday. “He was just such a lovely man. You needed to listen to him. He never wasted a word. His knowledge and his judgment were the two things that stood out. Some have knowledge but no judgment. He had deep reserves of both. He was able to develop views that others had no chance of getting to.”

Vale - Gerry Govett

Gerry Govett Biography

From his friends at Delta Gold: Gerry was part of the "glue" at Delta, always with practical, down-to-earth advice when circumstances required.I will miss his wise counsel... and, I remember driving Gerry and his wife around all of Delta’s Zim properties back in 1988. His advice and mentoring during this fortnight will remain with me forever. Sad news indeed... and, Gerry was always a true gentleman, maybe we should have a few drinks in honour of a great geoscientist at the Rag & Famish soon... and,the passing of another gentleman in the true sense of the word – a man to remember for his counsel, his kindness, his professionalism and his humility.Very sad news.

Vale - Lincoln McClatchie

Passionate geologist, lifelong baseballer and proud animal lover.
A remarkable man and a remarkable life


Vale - Greg Kary

8 July 1957 - 12 December 2018

Memorial Page at Red Metal

My heart aches with grief upon the realisation of Greg's passing. Over the last 19 years Greg and I have had lunch together almost every day, worked in the bush together on many occasions, and shared our love of rocks, science, family and the outdoors while tossing around our grand dreams for exploration success. Greg's kind gentle soul and aura instantly connected with everyone who met him. This humanity coupled with exceptional geological skills, an embrace of new technology and love of field work made him a rare gem. I have lost a true best friend whom I admired and respected but I'm comforted in knowing that his kindness and integrity will live on in our memories and actions for generations to come. Rob Rutherford.



David was educated at Brisbane Grammar and the University of Queensland then, after a brief stint at Bougainville, replete with a PhD from Melbourne University, he embarked on a lifelong career with CRA/Rio Tinto. David worked with and is remembered by many of the great characters of the global mining industry. A true leader, modest and funny, his was a life well lived but gone too soon. We send our condolences to Georgia, Sam, Rachel and grandson Leigh; and to David’s sister, Ann and brother, John.


Siegfried J. Muessig 1922 - 2018

The plaudits will be flowing in from everyone who fell into Sig’s orbit, especially from his time with US Borax, at Getty Oil and his close involvement with the SEG. At least two major mineral discoveries have Sig’s imprint; The Escondida porphyry copper deposit in Chile is one of the world’s great mines and the Jabiluka uranium deposit in Australia, one of the world’s best U deposits unfortunately trapped by political elements and which remains in the ground. He was a wonderful man, kind, thoughtful and a very good geologist. LA Times Obituary and Sig,from SEG Newsletter - Views

It is with great sadness that we note the passing of Neil Cole, well known by many in the SMEDG community, a regular on the Cruises and a well-known and respected Sydney mining community identity.

Vale - Bob Carter

1942 - 2016

Professor Bob Carter

Bob Carter epitomized the true scientist with his firm belief in the scientific method, belief in observable facts, belief in the primacy of science before politics, and a core belief derived from his geological training that what passes for weather and climate today has been experienced and documented many times over for millions of years of Earth’s history.


Vale - Peter Macnab

Peter Macnab

One of the best geologists and prospectors of his generation and, from his country upbringing, became a great bushman

Alex Copeland Obituary
Alex Copeland
Alex formed Search Exploration Services with Peter Elliot and used Scintrex IP equipment for several years, building Search’s reputation as a hard-working, reliable, geophysical contractor. However like many Australian geophysicists, he started to realise that equipment designed and built on the other side of the world wasn’t giving him the best answers in Australia, where electrically, the overburden often looked like sea water. At this stage he could have done as most other contractors do and look for an off the shelf solution. Undaunted or perhaps not realising the cost both in time and money in building his own system, he decided to do just that and with help from Phil Palmer on the hardware side and John Paine on the software side he built what is arguably the best IP system in the world and certainly the best system for Australian conditions. He took his systems all over the world.

Vale - Arnold Offenberg
13.07.1940 - 08.03.2015

It is with great sadness that we advise of the passing of Arnold. Beloved and devoted husband to Denise. Loving brother of Anneke and Tinneke. Wonderful father to Adrian, Daniel, Laura and Rochelle. Amazing Opi to Alex, Seb, Tess and Lachie. Loved and missed by all.

Farewell Dave Blake

1937 - 2014

Dave Blake Remembered

Dave, the accomplished geologist who was always seeking for the geological truth. "A net-vein complex fanatic – from the mixing of magmas."


1922 - 2013
Jack Thompson
Jack will be warmly remembered by many in the Sydney geological fraternity for his time with Amax. Michael Leggo recalls, in his letter to John Curdie, President of the Epping RSL sub-Branch, who kindly provided the attached article from the Club’s Routine Orders on Jack: "I worked with Jack for many years with the American mining company which you have mentioned (Amax), where Jack provided strong technical leadership and mentoring of many of our young geologists. His enthusiasm for geology never waned and as you have noted, he could become very passionate about his latest ideas and observations. He was one of the old-timers who would rather head out into the jungle with a horde of porters, food supplies and tent flies and build his camps as he went along rather than rely on helicopters and base camps." Another geologist remembers Jack from the Getty-Amax Magavara joint venture in Milne Bay Province in 1973: "Jack's aerial 3D photographs in PNG were legendary. I also remember his amusement at being able to talk to the Amax New York head-office using an SSB radio from a remote Highlands village in PNG via a Port Moresby telephone link."
Here is Jack's story by John Curdie.

Professor Willard C. "Bill" Lacey

1916 - 2013

Some sad news for the Australian geological community. I've just had an email from Bill's daughter Marian and son-in-law Mike Fellows (a Townsville-based geo) which in part reads: "A note to advise that Bill Lacy died December 7th in Tucson, Arizona. He was 97 and a half. He enjoyed a full life that would have been more than enough for two lesser men and had a gracious and peaceful ending. He had very fond memories of his time in Australia and the many people who made him feel welcome here. " Bill had a big impact on minerals side of geology down under, particularly during his time as Professor of Geology at James Cook University. His James Cook MSc course for geo's working in industry was legendary and touched the lives of many who are now industry leaders. He was a true gentleman geologist and was greatly respected by all he came into contact with.

Vale - Dave Suppel

1943 - 2011

Dave Suppel passed away on 11 March this year after a three year battle with cancer. Many in the minerals industry would have known Dave as the long-time Principal Geologist Metallic Minerals in the Geological Survey of New South Wales. To encounter a Dave Suppel in a career is to have had an experience one should value for a lifetime. Quality individuals such as Dave are unfortunately rarer than we would like to think. Accordingly, Dave Suppel's death is not only a loss to our professional cadre but also a loss to that small cohort of good men.
