Don has more than 25 years of civil/geotechnical engineering experience, specializing in design for tailings management facilities, construction, and project management for tailings dams and other mine infrastructure. He performed in roles as Engineering Manager; Project Director; Senior/Expert Review, and also as Engineer-of-Record for tailings facilities ranging from a few million tonnes to >1 billion tonnes of storage. He is the leader of the Environment and Sustainability practice in South America.
These projects have covered many different physical, climatic and seismic settings, and have also included many different types of mineralogy of tailings, including base metals, precious metals, iron ore and phosphate tailings.
In recent years, Don has provided technical direction and guidance for fully-integrated, multi-disciplinary tailings studies for major facilities, including the combination of relevant mechanical (dewatering, classification, transport, discharge); geotechnical (dam design and risk management); and social/environmental aspects (water balance, groundwater effects, communities, etc). Don is active in sharing knowledge, having presented in and participated at numerous technical conferences and workshops related to tailings and dam design.
