The Team

Dr John Gurney Chairman
(PhD Geochemistry)
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 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 20 years a top-rated research scientist by the South African Foundation for Research Development.

Dr Tom Nowicki
Technical Director
(BSc Honours Geology, MSc Minerals Exploration, PhD Geochemistry; P.Geo.)
Tom is a geologist and geochemist with 24 years of experience in mineral exploration and mining. He joined the MS Group in 1998 and has overall responsibility for the technical aspects of the Group's consulting and operations divisions. His role includes oversight and supervision of technical work undertaken by Mineral Services including: general mineral exploration consulting, the evaluation of the diamond potential of kimberlites and exploration samples, and geological and resource modelling of kimberlites and other mineral deposits. Tom has carried out extensive research in kimberlite geology, indicator mineral chemistry and geochemistry and has published several peer-reviewed papers on these topics.

Gareth Garlick
Senior Geoscientist – Project Manager, Vancouver
(BSc Honours Geology; Pr.Sci.Nat.)
Gareth is a geologist with 13 years of experience focussed primarily on the exploration and evaluation of primary diamond deposits. He has extensive experience in all aspects of the exploration cycle ranging from grassroots sampling and geophysical programs to advanced evaluation work and resource reconciliation on producing mines. Gareth currently manages the consulting work carried out in Mineral Services’ Vancouver office.

Dr Herb Helmstaedt
Associate Consultant Geoscientist
(Dipl. Geol., PhD Structural Geology)
Herb's main interests are Precambrian tectonics and the structural and tectonic controls of mineral deposits of all ages, including the tectonic settings of kimberlites and diamond deposits. He is Emeritus Professor at Queen's University in Kingston, Ontario, Canada, where he taught between 1974 and 2004 and served 10 years as Head of the Department of Geological Sciences and Geological Engineering. He supervised more than 60 graduate students and participated in the Canadian LITHOPROBE Program as leader of the Western Superior Transect from 1994 to 2004. He continues to keep a busy schedule with research, writing and teaching about diamond deposits and presently is Chairman of the Scientific Advisory Board for Canada's multidisciplinary Exploration Footprints Project jointly supported by the Canada Mining Innovation Council (CMIC) Exploration Innovation Consortium and the NSERC Collaborative Research and Development program.
