Barlow Medal for Best Geological Paper

For the best geological paper published in CIM publications during the preceding year

Origins & Conditions


Born on June 17, 1861, Alfred Ernest Barlow joined the Geological Survey of Canada in 1883, where he would help to define some of Canada’s most prolific mining regions. Barlow was the first geologist to recognize the Huronian belt in Ontario as a mineral rich location, and he wrote the book on the nickel and copper deposits of Sudbury. He served as president of CIM from 1912 until his untimely death in 1914. The Barlow Medal for Best Geological Paper was created in his honour, annually awarding a gold medal to those who publish the best paper on economic geology.

The Barlow Medal for Best Geological Paper criteria and other information:

  1. The award is presented annually, and there may be more than one recipient in any given year. 
  2. The winning paper will be selected by the Barlow Medal for Best Geological Paper Committee, chaired by the Vice-President-Elect of the Geological Society.
  3. The Committee shall present its report and recommendations to CIM Council not later than the last Council prior to the CIM Conference & Exhibition.
  4. When reasonably possible, the recipient shall be expected to receive the award in person during the course of the CIM Conference & Exhbition following the announcement of the award, or at such a time or place as CIM Council may direct.
  5.  Nominees should be CIM National Members.



Greg Gillstrom

Greg Gillstrom is a registered professional engineer, graduating from the University of British Columbia in geological engineering in 1990, and in electrical engineering technology from the British Columbia Institute of Technology in 1984. He has been working for 30 years in the mining industry on many properties around the word. In the past 15 years he has specialized in deposit modelling and ore reserve estimation using advanced mining software. In his current position as senior geological engineer with Imperial Metals Corporation, he has had the opportunity to help develop all Imperial's properties, including Mount Polley, Red Chris, and Huckleberry.


Christopher Rees

Chris Rees received a B.Sc. in geology from the University College of Wales in 1976, an M.Sc. from the University of Regina in 1980, and a Ph.D. from Carleton University in 1987.  After gaining some industry experience in Quebec and Yukon, he joined the British Columbia Geological Survey and worked on regional mapping projects in central and northern BC until 1997, and had a brief Structural Geology teaching position at the University of Victoria. In 1997 he was employed by Imperial Metals Corporation in the exploration for carbonate-hosted Zn-Pb-Ag in northern BC, and later for sediment-hosted gold in Nevada, US. Since 2003, Rees’s work for Imperial has concentrated on their porphyry copper mining and exploration projects in BC. His interests are in mapping, structural analysis, and understanding and modelling ore-forming processes and controls, and he has written or collaborated on several published research papers.
