Technical Advisory Committee

Dr. Julian Barnes received his B.Sc. (Hons) geology degree from the University College Swansea of Wales, UK and his PhD from the University of Leeds, UK. Dr. Barnes has extensive experience in major exploration/development project management, technical computing applications, due diligence studies, structural analysis, exploration and mining geology, technical audits, valuations, resource evaluations, ore reserve modeling and pit optimization. In 1987 Dr. Barnes founded Resource Service Group, an Australian-based consulting firm, where he has been involved in all technical and professional aspects of mining exploration and development, including project generation, exploration geochemistry, project scheduling and budgeting, exploration and resource computing and quality control programs. He has also worked on numerous bankable feasibility studies, mergers and acquisitions, and bankable due diligence studies for major international lending institutions throughout the world. From RSG's Perth office he has undertaken major projects around the globe involving a wide range of commodities, including precious metals, mineral sands, industrial minerals, nickel and copper-lead-zinc. Dr. Barnes was Executive Vice President of Dundee Precious Metals Inc. from 2004 to 2010.

Dr. Brett Davis received a BSc (Hons Class I) from James Cook University (1986) and a PhD from James Cook University (1992). Dr. Davis then worked as a production geologist at the George Fisher Pb-Zn mine at Mt Isa from 1987 to 1988. He was subsequently awarded an Australian Postdoctoral Fellowship from 1993 to 1995 and researched the tectonics of north Queensland, Australia, including the structural geological aspects to slate belt gold mineralization. Dr. Davis undertook further postdoctoral study from 1996 to 1998 and researched volcanic assemblages and sedimentary basin formation, including associated low sulphidation epithermal Au mineralization. During the period from 1992 to 1998, Dr. Davis published numerous scientific papers on topics including deformation processes, regional geology, slate belt Au, Fe-oxide Cu-Au, Cu-Au skarn mineralization and sediment-hosted Pb-Zn. Dr. Davis returned to the mining/exploration industry in 1999 and was an internal consultant for Delta Gold, working principally on Archaean lode gold systems. In 2003, Dr. Davis joined the international consultancy RSG Global as a Principal Consultant and worked on mineralized systems in numerous countries in SE Asia, Africa, Canada, Eastern Europe and Australia. In 2006, Dr. Davis joined Dundee Precious Metals as the Group Structural Geologist, working in Canada, Serbia, Bulgaria and Armenia. Dr. Davis joined Consolidated Minerals in 2008 as the General Manager - Geology, and oversaw exploration and mining at high-grade hydrothermal Mn deposits in NW Australia and Ni-sulphide deposits in the Eastern Goldfields of Western Australia. Since 2009, Dr. Davis has been working as a structural geologist on several projects in NE Africa, West Africa, Thailand and Serbia. Dr. Davis holds adjunct research positions at James Cook University and the University of Western Australia.

Dr. Graybeal received his A.B. from Dartmouth College (1960) and MS (1962) and PhD (1972) degrees from the University of Arizona. He worked as resident geologist at the Silver Bell mine in Arizona, as an instructor in economic geology at the University of Arizona in 1969, and spent most of his career in metals exploration with ASARCO Incorporated, retiring in 2003 as chief geologist. He is a member of the SME, SEG, GSA, AGS, SGA, and PDAC, has worked on committees for several of those groups, and is a past vice president of the Society of Economic Geologists. He has also served on two committees of the National Research Council, on geoscience advisory boards of several universities, and has published on various scientific and professional subjects. He now consults, participates in a porphyry copper research project in Arizona with the U. S. Geological Survey, and is a director or advisor to several public exploration and mining companies. He is a recipient of the SME Dickerson award (recognizing professionalism and contributions to the mining industry) and the SEG Marsden award (for outstanding service to the Society).

Dr. Jelenkovic received a Master of Mineral Deposit Exploration degree (1982) and a PhD (1987) degree in Geological Sciences from Belgrade University, Serbia. He is currently a full professor (Ore Deposits, Metallic Mineral Deposits, Genesis of Ore Deposits, Prospecting of Ore Deposits, Metallogenic Analyses and Prognostic Maps of Mineral Deposits) and the Chief of Department for Economic Geology at the Faculty of Mining and Geology, Belgrade University. He was elected as a Corresponding Member of the Academy of Engineering Sciences of Serbia in 2004. He has 26 years experience in the field of metallic mineral deposit assessment and metallogenetic analyses of Serbia, including various professional associations within the Ministry of Energy and Mines, Ministry of Science and Technological Development and Ministry of Environment and Spatial Planning, Republic of Serbia. Dr. Jelenkovic has authored more than 140 scientific papers, 12 monographs and books, 53 scientific studies, projects and reports of geological exploration (Cu-Au, Pb-Zn, U etc.), as well as 'Elaborati of Ore Reserves' (Serbian Resource & Reserve Statements). As President of the Republic of Serbia's Commission for Ore Reserves (2004-2009) and a current member of the Commission he has audited more than 200 national projects and reports of geological exploration and 'Elaborati of Ore Reserves'. Previous tenures include the Serbian National Geological Institute "Geoinstitut-Belgrade", where he has served as a field geologist (1983-1986).

Dr. Tosdal received a A.B. from the University of California at Santa Barbara (1974), a M.Sc. from Queen's University (1978) and a Ph.D. from the University of California at Santa Barbara (1988). Between 1978 and 1999, Dr. Tosdal worked for the U.S. Geological Survey and as an independent geologist for the mining industry. From 1999 through 2008, he was the Director of the Mineral Deposit Research Unit at the University of British Columbia where he supervised collaborative industry-university research projects on 5 continents investigating intrusion-related Au deposit, Carlin-type sedimentary rock-hosted deposits, porphyry and epithermal systems, VMS deposits, carbonate-hosted polymetallic deposits, integration of geology and geophysical inversion, and volcanology of kimberlite. In 2009, he became an independent geologist based in the eastern United States from where he consults with the minerals industry around the world. Dr. Tosdal also continues an affiliation with the Mineral Deposit Research Unit through on-going collaborative industry-university research. He has worked on geologic, tectonic, and metallogenic problems in the Cordilleras and Cratons of North and South America, Africa, Asia, and Australia.
