  • Pioneered in the development and promotion of mine to mill optimisation concept at several global mining companies in Australia, Canada, Chile, Ghana, Indonesia, Peru, Papua New Guinea and USA that resulted in significant improvements in mill throughput.
  • Developed tools and techniques to minimise ore loss & dilution and improve fragmentation to maximise downstream process efficiency.
  • Developed new blast design methodologies to minimise blast induce damage and ground vibrations.
  • Developed Mine to Mill Optimisation Workshop and delivered at several international venues including annual Society of Mining Engineering (SME) conferences.
  • Lead several research projects to better understand rock blasting mechanisms and developed tools to predict fragmentation, throw and ground vibrations.
  • Implemented projects at several coalmines in Australia that resulted in significant improvement in overburden casting and reduction in coal losses.
  • Developed tools and systems to analyse the quality of field implementation and its impact on final outcomes.
  • Involved in the development of Drill and Blast Guidelines for BHP Billiton and Thiess Mining Operations. Established a community of practice for drill and blast practitioners in Thiess to share the knowledge and to implement the best practices.


  • AusIMM Mineral Industry Operating Technique Award for Y 2002 for implementing the Mine to Mill project.
  • Ian Morley prize in 1992for the best performance as a postgraduate student at the JKMRCC.
  • Authored around 60 technical papers (in various international conferences, journals and magazines), 3 theses and one book in the field of explosives and blasting.



Malcolm has applied fundamental comminution research to design and process improvement on over 60 mines worldwide during 30 years at Mintek, UCT, and the JKMRC. His work is published in over 200 papers. Malcolm collaborates extensively, with close compatriots on 5 continents forming the Global Comminution Collaborative. Malcolm’s research vision is of integrated total process simulation as a tool for innovation – linking geology, mining, energy and size reduction, gangue rejection and recovery into flexible process design and process optimisation.

Recent work on advancing the mine to mill concept has focussed on turning this knowledge into an applied process tool for medium to short-term planning and daily operation through implementing blast design, ore tracking and dynamic model-informed milling control. The work at Barrick Cortez mine demonstrates some of this approach.
