Dave Mackintosh has just passed 50 years in the potash mining industry where he started as a rock mechanics technician in 1969 for Cominco (Agrium, now Nutrien). His supervisor at the time was Jim Popowich, past president of CIM. He remained as a technician for a number of years, and became a local authority. He finally finished his geology degree at the University of Saskatchewan in 1985, and after 26 years with Cominco, formed ADM Consulting Limited in 1996. Since then, he has been fortunate to work on projects in Thailand, Europe, Britain and throughout North and South America.
