Biography

A.C.S.M. Mining Engineering, Camborne School of Mines, Cornwall, United Kingdom, 1968

M.Sc.(Eng.) Mining Engineering, Queen's University, Kingston, Ontario, Canada, 1973

Work Experience

  • Falconbridge Nickel Mines, Sudbury, 1968-1971
  • Brenda Mines Ltd., Peachland, B.C. 1973-1986
  • Barrick Goldstrike, Elko, Nevada, 1993-1994
  • Niugini Mining, Antofagasta, Chile, 1997

Earlier work while employed in the mining industry produced the first computerized survey slope monitoring system which enabled the lowest grade mine in the world to successfully mine higher grades despite a major haul road instability. The on-site application of geostatistics enabled grades to be better predicted and lead to the development of one of the first interactive mine planning computer packages.

Work with Quebec Cartier produced the first robotic slope monitoring system with real time radio telemetry transmission of data for interactive analysis. Slope monitoring systems using low cost total stations as robots have also been developed. The first conversion of a large electric shovel to remote control was completed in 1991, and worked successfully at Brenda mines.

Work with truck fleet optimization, including overhead trolley assist, has helped in improving productivity and reducing costs. Software development includes a grade estimation package and geostatistical programs. Using AutoCAD as a graphic display and programming tool, ore deposits can be modelled and underground mine planning carried out.

Current research

  1. development of an open pit mine planning package
  2. practical application of grade simulation and its effects on mine planning
  3. producing truly accurate grade estimates by conventional means
  4. providing comparable & meaningful methods of classifying mineral resources.
