TECHNICAL COMMITTEE

Technical Team

Dr. R. Scheepers (Petrology, Geochemistry, Exploration Geology) (President, Director and CEO)

Dr. Scheepers’ involvement with geology and the mining industry stretches over a period of 28 years. He started off as a researcher at the Fuel Research Institute of the Council for Scientific and Industrial Research (CSIR) of South Africa where he gained experience in the composition and characteristics of various South African coal fields. This was followed by a 2 year period as a geologist at a South African gold mine (Witwatersrand gold deposits) where he gained experience in underground geology, underground and surface exploration, and gold exploration project planning. He then joined the University of Stellenbosch (S.U.) where he became associate professor in mineralogy/ petrology in 1999. He obtained his Ph.D.(S.U.) on the distribution of radioelements (U, Th, K) in granites in 1990 following a seven month period at the Centre de Rescherches sur le Geologie de la Uranium (CREGU) in Nancy, France. Since 2005 he has been a full-time consultant and director of companies based in the Republic of Tanzania. Dr. Scheepers is a registered Professional Natural Scientist in Geological Science and a member of:

Geological Society of South Africa (since 1984).
SACNASP Registered (since 1984).
The Mineralogical Society of South Africa (1996 to 2001).
Geological Society Western Province Branch (1985 to 2002).
Society of Geology Applied to Mineral Deposits (1989 to 1997).
Council member of the Geological Society of South Africa (1996 to 1999).

Dr. P.G. Gresse (Structural- and Exploration Geology)

Dr. Gresse is a renowned structural geologist with a lifetime experience in Africa. He has extensive experience in field geological mapping, structural geology and basin analysis. Dr. Gresse has been involved in various international research and mapping programs specialising in Late Proterozoic geology. Dr. Gresse has published widely in local and international journals (33) and has attended and presented papers at numerous international conferences and symposia (25).

Mr. C. Lötter (Geophysics and Exploration Geology)

Mr. Lötter has 30 years experience in mining and exploration geophysics and has run his own consulting and contracting business for 20 years. He has extensive experience in the Greenstone terrains of southern, eastern and western Africa as well as the Zambian and Botswana Copper belts. Mr. Lotter is involved in survey planning and design and QC/QA and interpretation, including 2D/3D forward and inversion modelling, on a daily basis.

Mr. E. D. Ole Naiko (Mining Engineering and Mineral Economics)

Mr. E.D. Ole Naiko (a mining engineer by training) conducted his post graduate studies in Mineral Economics and Metallurgical Engineering at the Colorado School of Mines. He has been an executive director of the Tanzania Investment Centre and the manager of various state mining companies, including gold mining companies, as well as an executive director of the TIC (Tanzania Investment Centre) in Tanzania. Mr. Naiko plays a major role in promoting the minerals industry of the country and attracting investment to the sector.

Mr. B. McDonald (Exploration- and Economic Geology)

Mr. McDonald is an exploration geologist with vast experience in Africa, South America, Mexico, and Cuba. He has been exploration manager on numerous successful projects for various prestigious companies including Billiton S.A.(aka BHP Billiton) and GENCOR S.A. as well as managing exploration projects for smaller companies including Trans Hex, the O'Okiep Copper Company, and along with numerous others. The commodities within his experience portfolio span from base metals, gold, precious metals, asbestos, uranium, diamonds, and coloured gemstones. His gold experience covers the spectrum from sedimentary to high grade metamorphic related gold. Complementing his geological achievements are his people skills, often successfully managing a work force of more than 100 people, including several teams of professionals concurrently under difficult operational conditions.
