Innovative Applications of portable X-ray diffraction (pXRD) and X-ray fluorescence (pXRF) for base metals and gold exploration

Innovative Applications of portable X-ray diffraction (pXRD) and X-ray fluorescence (pXRF) for base metals and gold exploration

In this webinar Professor David Cohen (President of the Academic Board of University of New South Wales and President of Australian Geoscience Council) will present examples of pXRF and pXRD used in various gold and base metal exploration projects. Professor Cohen has been working with both XRF and XRD technologies in conjunction with exploration companies for many years. He has extensive experience in exploration geochemistry, biogeochemistry, regional geochemical mapping, metal extractions and data processing. The webinar will focus on interesting and innovative applications of pXRF and pXRD beyond the traditional, that new and existing users of these technologies may not be familiar with. The webinar will be hosted by Olympus’ Director of International Mining, Todd Houlahan, who has been working with pXRF technology across the globe for the last 20 years.

Director, International Mining Group

Todd Houlahan graduated from the University of Newcastle, Australia in 1993 with a Bachelor of Applied Science (Environmental) majoring in soils and hydrology. He then worked for 7 years as a contaminated land consultant in Australia and the UK with various companies before being introduced to handheld XRF in 2000 while remediating a Pb contaminated site in Sydney. From 2000-2004, he worked in Australia and used handheld XRF as a consultant, a contractor and in sales capacities on large number and wide variety of Geochem projects. From 2004-2008 Todd was on the metaphorical coal face of the mass introduction of modern x-ray tube based units to the exploration and mining sector supporting distributors and customers in the EMEA region. Since 2008, Todd has led the International Mining Group in a global capacity at Olympus and is now based out of Hertfordshire in the UK. For the past 15 years, he has dedicated his career to portable XRF applications in the minerals industry. His passion is best practice application of the technology, customer training and unique applications.
