Past President of CIM (2010-2011)

Christopher Twigge-Molecy was born in London, U.K. and undertook his undergraduate studies in Mechanical Sciences at Cambridge University. He moved to Canada in 1968 to pursue a PhD in fluid mechanics. After graduating, he worked for Hatch as a professional engineer for five decades and was considered both a leader and technical innovator in the minerals and metallurgical field. As an advocate for sustainable development, Chris contributed widely to its adoption within the Canadian mining industry through his involvement in and leadership of CIM, MetSoc, the Canadian Mining Innovation Council and later the Canada-China Business Council. As a lecturer-presenter of technical papers all over the world, Chris had a constant drive to teach, coach and explore new approaches and ideas in minerals and metallurgical engineering. During his career he held six patents, and his inventions included developing a new way to maximize arsenic removal when processing gold ore and creating a novel approach to ventilating large complex industrial buildings. 

Chris Twigge-Molecey passed away on January 8, 2024. In 2025, his family were honoured to accept the Robert Elver Mineral Economics Award on his behalf.
