Peter Stacey has over 50 years’ experience in all aspects of pit slope and mining geotechnical
design, project management and review. He holds a B.Sc. Hons. degree in Geology and a
D.I.C. from Imperial College, London, and is a registered Professional Engineer in Canada and
Fellow of the Engineers of Canada, and a Chartered Engineer in the UK. He worked for the
Geological Survey of Sweden and subsequently with the Iron Ore Company of Canada before

worked primarily in the areas of pit slope design and the application of geotechnical
engineering to the operational aspects of open pit mines, as well as a project manager for

reputation and worked on open pit geotechnical projects in North and South America, Africa,
Southeast Asia and Australia.
In 2003, Mr. Stacey retired from Golder Associates and formed Stacey Mining Geotechnical

open pit mining. In this capacity, he has served as a review consultant for several international
mining companies, including Anglo American, Barrick, BHPBilliton, DeBeers, Debswana,
Kinross Gold, Newmont Goldcorp, Rio Tinto, Teck Resources and Vale, as well as for a
number of smaller mining and consulting companies.

which was published in 2009, and “Guidelines for Open Slope Designs in Weak Rocks”, which

pit slope design through UBC/Infomine and to mining company teams.
He is currently Chairman of the Large Open Pit Project Sponsors’ Representative Committee,
