Applied Geochemistry in Exploration: The Path to Discovery

    Published on August 17th, 2021

    Join Principal Geoscientist, Dr Pim van Geffen at the Applied Geochemistry in Exploration: The Path to Discovery 2021 Virtual Conference when he presents on ‘Compositional Domaining of Ore Deposits and Estimating Value Modifiers from Geochemical Data’ between 7 to 8 September 2021.

    Hosted by the Chile Explore Group, this conference will seek to host a number of presentations on pXRF, Mineral Chemistry, Geomet, Chemical and Spectral Analysis.

    Dr Geffen will present at 10.15 am on Wednesday 8 September.

    Abstract

    Grade has no value if it cannot be extracted profitably. The efficiency of mining, milling, and metallurgical processing depends on the physical and chemical properties of the rock mass, which in turn are a function of its mineralogy. But the cost of acquiring large volumes of mineralogical data for all critical phases at all relevant scales can be prohibitive. If adequate assay data are generated from exploration drill holes, combined with early environmental and metallurgical variability testwork, these can be used to identify unbiased compositional domains and to calculate proxies for mineralogy, plant-performance parameters, and key environmental measures.

    Pim is a professional geoscientist with more than 15 years’ experience in mineral exploration and mining across the globe. He is a leader in the fields of geochemistry and geometallurgy in the Americas and is passionate about innovation and improved business practice in the sector. Across exploration to operations, closure and remediation, Pim focuses on rock-property data integration and process optimization throughout the mining value chain. He sees tremendous potential value in unlocking hidden information through geoscientific data gathered and not used to its full potential to characterize ore and waste, minimize operational risk, and maximize return. Pim has been a significant contributor across the industry; having delivered a plethora of public short courses and conference talks on geochemical data analysis and its geomet applications. He has provided in-house training to mining companies and academic institutions on ioGAS software, portable X-ray fluorescence analysis and infrared reflectance spectroscopy, and has served as a guest lecturer at the University of British Columbia and Queen’s University.
