Ken Johnson

The Braúna Diamond Mine – The Development of Brazil’s First Kimberlite Diamond Producer

Ken Johnson has 27 years’ experience in diamond exploration, development, production and project finance.  During his career, he has explored for, and developed diamond deposits in Canada, central and southern Africa, and most recently in Brazil, spearheading the development of the Braúna diamond mine, South America’s first diamond mine developed from a kimberlite deposit.  Ken founded Lipari

Mineração in 2008 and subsequently raised over US$65 million in financing for the development of the Braúna mine.  Prior to Lipari, Ken was President and CEO of Vaaldiam Resources Ltd, a publicly-traded company listed on the Toronto Stock Exchange that he formed in 1998, which financed the exploration and development of diamond projects in South Africa, Canada, Central Africa and Brazil.  In the Central African Republic, Ken was responsible for the discovery and development of the MBala alluvial diamond mine, which was operated as a joint venture with the Trans Hex Group of South Africa, and was also responsible for the discovery of the Passandro gold deposit, a 2.3 million ounce gold deposit now owned by Axmin Inc.  In Brazil, Vaaldiam financed the development of alluvial diamond mines in the states of Minas Gerais and Mato Grosso, kimberlite exploration in joint venture with Rio Tinto in the Pimenta Bueno diamond district in the state of Rondônia, as well as the acquisition, initial drilling and bulk sampling of the Braúna kimberlites in Bahia.  Ken holds an Honors B.Sc. in geology from the University of Windsor in Canada and earned his certification in 2002 as a rough diamond grader and valuator in Johannesburg, South Africa.  He has been a frequent speaker on the diamond industry at the annual convention of the Prospectors and Developers Association of Canada, where has was a Director from 1998 to 2001.

Her areas of expertise include petrography and development of geological models of kimberlites and lamproites in support of exploration, evaluation, resource estimation and mine planning. She has contributed to projects throughout Canada, in southern, central and west Africa, India, Australia, Russia and Ukraine.

Kimberley conducts audits of geological models, designs drilling and sampling programs, provides training in logging, geological data acquisition, sampling methods, and petrography. She is a contributing author of several NI 43-101 technical reports on kimberlites and has presented various short course and conference presentations on kimberlite geology and evaluation.

Casey Hetman

The Gahcho Kue and Kelvin kimberlite clusters, NWT Canada: advancements in exploration and geology over 20 years

Casey Hetman is a Corporate Consultant based in the Vancouver Office. Casey graduated from the University of Toronto, Department of Geology and is a registered Professional Geoscientist in British Columbia, Ontario and the Northwest Territories and Nunavut. He has more than 20 years of experience within the exploration and mining community globally.

The focus of Casey’s work has been on diamond, gold and base metal deposit geology. He has undertaken field investigations in 18 countries, at over 40 different mining operations. These investigations have involved a variety of work, including detailed examination of drillcores, outcrops and mining exposures combined with the reviews of various data sets including petrography, geophysics and grade information. 3D geology models have been produced for the purpose of guiding and directing exploration and mine planning activities as well as for resource classification and NI 43-101 reporting.

In addition to economic geology, Casey is actively involved in research and development. He has authored and coauthored 12 manuscripts and he regularly participates in geology conferences and delivers technical presentations on kimberlite geology internationally.

Barbara Scott Smith Ph.D., P.Geo.

Kimberlite Terminology and Classification: An Improved and Rationalised Staged Approach

Barbara earned her Ph.D. in 1977 from Edinburgh University and then worked as a principal research mineralogist on diamond-related ventures for Anglo American Research Laboratories and the De Beers Kimberlite Petrology Unit in South Africa. Since 1982, she has been based in Vancouver, Canada as an independent consultant offering specialist services in applied kimberlite geology relating to world-wide diamond exploration and mining projects for a variety of major to junior companies.

Professional travel has taken Barbara to 25 countries (USA, Greenland, Australia, Europe, South Africa, Lesotho, Zambia, Namibia, Botswana, Zimbabwe, Tanzania, Ivory Coast, China, India, Brazil, Yakutia and Arkhangelsk in Russia). Also, over the last two decades investigations have included most kimberlite fields across Canada. Consulting and related research has led to many publications including over 40 peer reviewed papers.

During the period April 2001-October 2003 Barbara created and directed the De Beers Canada Kimberlite Petrology Unit until its planned transfer from Vancouver to the head office in Toronto. Since then, in addition to continued consulting, Barbara now continues to share her extensive experience and expertise through Scott-Smith Petrology Inc. which now also offers unique opportunities to learn about kimberlites through “hands on” courses, mentoring and coaching. The dedicated training facility has also become a focus for kimberlite research.

Throughout her career Barbara has participated in mentoring and training a number of M.Sc. and Ph.D. students and many employees of client exploration and mining companies. In 2000 she became Adjunct Professor at the Earth and Oceanographic Sciences, University of British Columbia where she participates in kimberlite research with Maya Kopylova (Diamond Exploration Laboratory) and Kelly Russell (Volcanology and Petrology Laboratory), postgraduate teaching and supervising postgraduate students.

In 2003 she co-convened the 8th International Kimberlite Conference and in 2006 the International Workshop on Kimberlite Emplacement and was Guest Editor of both Proceedings Volumes. Professional affiliations include: Association of Professional Engineers and Geoscientists of the Province of British Columbia, Canada (P. Geo.) and Chartered Geologist of the Geological Society of London, UK (C. Geol.). Barbara is the 2009 recipient of the Hugo Dummett Diamond Award for excellence in diamond exploration and development.
