Geological Survey of Canda, Economic Geology Report 31.Tom Eadie graduated with a BSc(Hons) in geology and geophysics from the University of British Columbia in 1976. After a brief stint with Gulf Oil of Canada as a seismic interpreter, he worked for two years with Gcolerrex as a party chief on field crews. Returning to university, he obtained an MSc in geophysics from the University of Toronto in 1980, working on electrical methods in oil exploration. He then joined Cominco, Vancouver, in part helping to develop EM field and interpretation methods for Pb/Zn exploration. From 1983 he has been on an Aberfoyle-Cominco exchange with Jovan Silic.Jovan Silic graduated from the University of Western Australia in 1971 with first class honours in physics. From 1971 to 1975 he worked with the BMR on Australian National Antarctic Research as a geophysicist. From 1975 to 1979, still with BMR, he worked on research into electrical prospecting methods. He was also involved in acquisition and interpretation of regional geophysical data, emphasising automated in-version techniques on potential field data. In 1979. he joined Aberfoyle Exploration where he was in charge of the geophysical programme. From August 1983, he has been on an Aberfoyle-Cominco exchange with Tom Eadie.Doug Jack graduated in mining geology at the University of the Witwatersrand, Johannesburg. South Africa, in 1976. He then joined Union Carbide Exploration initially as a photogeologist working principally on Karoo uranium. From 1979 he ran an uranium exploration programme in Botswana where he spent 2 1/2 years. In 1981 he was transferred to Australia where he worked on uranium exploration in the Northern Territory, Archean gold in Western Australia and tungsten in New South Wales. He joined Aberfoyle in January 1983, based in Tasmania he was the field geologist immediately prior to the discovery of Hellyer.AUGUST 2020 PREVIEW 52'
