A graduate of McGill University in Mechanical Engineering (1961), Dan has worked almost exclusively with mining projects, beginning with Bechtel Corporation in San Francisco. Projects included five iron ore beneficiation plants, three copper flotation plants, a uranium concentrator, two tar sands plants, and numerous industrial minerals and precious metals projects.
Although most project work has been from conception to commissioning, Dan is well known for his conceptual expertise, notably the pre-feasibility study for the giant Collahuasi Project in Chile that has been constructed essentially as envisioned by the project team in that first go-around.
He is currently president of Dan Mackie & Associates, INNOVAT Limited (which has proprietary leaching technology), and Saymwa Communications. He is author of over 100 technical papers and a practical textbook, "Engineering Management of Capital Projects" - McGraw Hill-Ryerson (1984).
