MEET OUR PRESENTERS
Dennis Arne
Principal Consultant
Dennis has over (30) years’ experience in exploration in a wide range of environments in both the minerals and the petroleum industries, as an academic, and in geological surveys. In recent years he has been involved as a consultant in the development of exploration programs for precious and base metals exploration in Australia, North America, South America and the Middle East. Specifically, this has included contributing to exploration targeting reviews and understanding gold and base metals mineral systems, the design, management and interpretation of surficial geochemical surveys, the interpretation of lithogeochemical data, the preparation of QA/QC protocols, reviews of geochemical data quality, and contributions to NI43-101 and JORC/Valmin technical reports. He has published extensively in the areas of applied geochemistry, economic geology and thermal history analysis for tectonic and petroleum exploration applications.
Dr Carl Brauhart
Principal Geologist
Dr Brauhart is an exploration geologist with more than 20 years’ experience in gold and base-metal exploration, spending much of that time working in frontier areas of Western Australia on grassroots projects. He has a particular interest in geochemistry, both exploration geochemistry and ore deposit geochemistry, and a passion for field work, particularly mapping. Carl has maintained a close association with the Centre for Exploration Targeting at the University of Western Australia where he is the lead researcher on the OSNACA Project (an ore deposit geochemistry research effort).
