The Team
Dr John Gurney (PhD Geochemistry)
Chairman
John’s specialty is the geochemistry of diamond indicator minerals, on which he has published widely. He provides high-level input into the consulting division's technical assignments and plays a key role in the evaluation of diamonds, microdiamonds and the diamond potential of kimberlites. He is also involved in the development of mineral exploration strategies for clients and has general oversight of the MS Group’s field and laboratory exploration methodologies. John is an Emeritus Professor of Geochemistry at the University of Cape Town (UCT). He was also the Head of the Kimberlite Research Group at UCT and for many years a top-rated research scientist by the South African Foundation for Research Development.
Dr Tom Nowicki, P.Geo. (B.Sc Hons Geology, MSc Minerals Exploration, PhD Geochemistry)
Technical Director
Tom has overall responsibility for the technical aspects of the MS Group’s consulting, laboratory and operations divisions. His role includes general mineral exploration consulting, the evaluation of the diamond potential of kimberlites and exploration samples and geological and resource modelling of kimberlites. Tom has carried out extensive research in kimberlite geology, indicator mineral chemistry and geochemistry and has published several peer-reviewed papers on these topics.
Kimberley Webb, P.Geo. (B.Sc Hons, MSc Geology)
Principal Geoscientist
Kimberley's consulting roles include evaluating the diamond potential of kimberlites and developing geological resource models through multidisciplinary dataset integration and analysis. She also conducts project reviews, technical audits and specialist geological investigations and is involved in the training and development of kimberlite geologists.
Alexandra Mauler, P.Geo. (MSc, PhD Geology)
Senior Geoscientist
Alexandra’s main consulting services focus on petrography outside of the diamond industry. She provides applied mineralogy in the field of environmental, mining and exploration geology. Alex is also responsible for specific analytical services related to mineralogy, including SEM-based studies, X-ray diffraction and electron microprobe analysis.
Kendra Siemens, P.Geo. (BSc Geology)
Project Geologist
Kendra is the Technical Supervisor and Quality Manager based in Cape Town. She is responsible for the implementation of a quality management system in the laboratory that complies with the ISO 17025 standard. Kendra is also involved in consulting work with regard to kimberlite evaluation and prioritisation. She has been trained by Dr John Gurney to undertake microdiamond and macrodiamond characterisation and evaluation work.
