Jessica Stromberg presents Hyperspectral mineralogy for exploration: More than white mica & chlorite

Jessica Stromberg (CSIRO) presents 'Hyperspectral mineralogy for exploration: More than white mica & chlorite' for the GSA SGEG August Facets of Exploration Webinar

Abstract:
Hyperspectral tools provide fast, field-friendly, and cost-effective methods for extracting mineralogical information from regional to drill core scale. Hyperspectral mineralogy can add value to exploration programs at all stages, through a broad range of applications from mapping alteration footprints and transported cover, to improving geological logging and modelling other rock properties. Recent years have seen increased uptake of hyperspectral tools in mineral exploration, as well as rapid advancements in instrumentation, data processing, and data integration methods, which have expanded the available spectral range and subsequent applications. This webinar will provide a brief introduction to hyperspectral mineralogy and recent advances in instrumentation, and explore the role that hyperspectral methods can play in greenfield exploration to the near-mine context through a series of case studies. These case studies will highlight applications of hyperspectral mineralogy beyond white mica and chlorite, including the integration of hyperspectral data with other geoscience datasets. Participants will gain an understanding of the current state of the art in hyperspectral mineralogy, some of the challenges that exist, and opportunities for its application in mineral exploration.

Bio:
Dr Jessica Stromberg is a Research Scientist in the CSIRO Mineral Resources (CMR) Discovery Program. She is an ore deposit geologist with expertise in the application of geochemical and spectroscopic techniques to ore systems, and is broadly interested in improving the workflows in which we collect and integrate geoscientific datasets. She is a member of the National Virtual Core Library, Data Mosaic, and MinEx CRC Project 3 teams, and has worked across multiple commodities, with a focus on copper and gold, applying the combined use of lab and field spectroscopic and geochemical techniques in the exploration and orebody knowledge context. She completed her PhD at the University of Western Ontario in Canada where she worked throughout Canada’s Superior Province on Archean orogenic gold systems and gained industry experience working as an underground production geologist.
