Exploration in data-rich environments, close to existing mines, has become a preferred and successful method of increasing company resources in recent years. With this exploration philosophy in mind, CODES is proud to present a Masters-level two-week intensive training program designed to bring participants up to date with the latest exploration techniques.

The course will cover cutting-edge technologies in geophysics, geochemistry, hyperspectral reflectance and 3D visualisation, using real data from world-class mineralised districts. The program is presented by expert teaching staff from CODES and leading minerals industry professionals.



John Ashton worked in several roles for Boliden at the Navan Zn-Pb mine in Ireland including Chief Mine Geologist and as Chief Exploration Geologist up to retirement in 2019. Earlier work includes PhD research on Zn-Pb-Au vein geology and litho-geochemistry in Central Wales, and as mine geologist at the Silvermines Zn-Pb orebody in Ireland. Experience and interests include 3D geological modelling, resource estimation, the genesis of carbonate-hosted Zn/Pb deposits and exploration for base metal deposits. Since retirement he has been providing consultancy services to Boliden’s exploration JVs in Ireland.

He started working life as an exploration geologist before transitioning to an exploration geophysicist. He has worked for international and national majors , global contractors and for the past 25 years as a consultant within consulting groups. He provides everything from broad geoscience advice to single prospectors and juniors with low levels of technical expertise through to high level specialist geophysical advice to large company geophysicists and other consulting groups.
Scott Halley is an independent consultant specializing in exploration geochemistry, and the application of multi-element ICP geochemistry and SWIR analysis to mapping alteration mineral zonation patterns around hydrothermal systems. Over the past 20 years, Scott has consulted to more than 180 mining and exploration companies in more than 25 countries.
Kate Hineis the Principal Consultant for, and a Director of, Mitre Geophysics which has been advising the mining industry since 1980, and has worked on projects across the globe including both Antarctica and the Arctic. Kate has 20 years experience working on a wide variety of commodities in a range of different geological settings, with some of the most interesting and exciting discoveries in Australia and worldwide. In Kate’s portfolio of discoveries, several are more than 400m below surface with no surface indications. Her particular specialty is high quality EM processing and interpretation, but she also has unrivalled expertise in MMR methods, used to detect and define weakly conductive mineralisation. Kate is also active in research and publication and has won two ‘Best Paper’ awards from the Australian Society of Exploration Geophysicists. She is also regularly invited to speak at industry events. Kate graduated in 2002 from the University of Tasmania.
Terry Hoschke joined Geopeko in the 1980s exploring for a number of commodities including gold, uranium and base metals. This included conducting IP and magnetic surveys at North Parkes. He managed the Darwin exploration office for North Limited for 3 years from 1992 and subsequently worked on porphyry exploration for North in Indonesia. He worked for Normandy/Newmont from 2001 to 2013 during which time he completed an MSc thesis on the geophysics of porphyry and epithermal systems. This was subsequently published by CODES. He is currently a geophysical consultant, based in Perth. He has worked on a number of projects in NSW including geophysics in the Cadia area for Newcrest.
Ned Howard is Principal Geologist, Technical at Evolution Mining. After graduating from UTAS with BSc Hons in 2004, Ned worked as an exploration geologist with Barrick and junior companies in Australia, Indonesia, PNG and Canada, before joining Evolution Mining in 2013. With Evolution, he has held geoscience and project generation roles supporting their near mine and greenfields exploration efforts. He specializes in geochemical and spectral applications and has worked on a number of gold deposit styles, predominately Archean greenstone and epithermal.
David Isles is a semi-retired geophysicst. He provides consulting and training services through Southern Geoscience Consultants focused on interpretation of aeromagnetics, gravity and radiometrics in mineral exploration applications
