Max is a principal engineer and has twenty years’ of experience in mining geotechnics. He has provided support and consulting services to open pit mining operations and greenfield projects in Europe, Asia, Africa and South America and has a broad range of experience having undertaken scoping, pre-feasibility and feasibility level studies, support to operations, technical reviews and due diligence for a range of commodities within varying geological environments.
Chief Geotechnical Manager, First Quantum Minerals Ltd, Spain
Stephen has over 20 years´ experience in geotechnics, working directly on operations and previously as a consultant. He has extensive experience in ground control on operational open pits and tailings installations, the geotechnical aspects of mine design for both open pit and underground, the implementation of state of the art monitoring systems, and ensuring mine waste management is compliant with best available techniques and practices. His current interests are the modelling of blast disturbance into pit slopes applying transitional damage factors on constitutive models, and the interactions between open pits and their underground sections during the transitional phase. For the last eight years he has successfully implemented those ground control systems at Las Cruces mine in Spain and is a founding member of the European Ground Control Group.

Teofilo da Costa
Geotechical Risk Management, Vale S.A., Brazil
In 1998, Teo joined Vale as a short-term geologist for iron ore mines and in 2004, moved to geotechnical team focus on slope monitoring and stability, slope designing and data base collection for several open pits. In 2014, Teo joined the Australian Centre for Geomechanics as a PhD student to undertake geomechanics studies. His PhD was sponsored by Vale. In 2017, Teo moved to geotechnical risk management supporting the local geotechnical team for open pit operations, risk, final slope design, monitoring and new technologies applied for slope stability for all of Vale’s ferrous and coal mines. Teo is one of Vale’s representatives for the industry’s acclaimed large open pit research project. Teo graduated with a geological engineering degree from the Federal University of Ouro Preto, Brazil in 1994 and in 1999, he obtained Honours in metallogenesis at State University of Campinas, Brazil, and Masters of Science in geotechnics applied to mining in 2009 at Federal University of Ouro Preto, Brazil.
Professor Phil Dight
Slope Stability 2020 Symposium Chair
Professor of Geotechnical Engineering, Australian Centre for Geomechanics
Phil has been involved with the development and design of ground support for mining applications since 1975. Phil joined the ACG in 2008 and has since been working on stress memory effects in rocks, ground support applications, slope stability problems (including the use of microseismicity to understand failure mechanisms), and 3D rock properties. In 2017, Phil commenced a four year MRIWA project aimed at investigating the issues of strainburst vulnerability in underground mines.
