Simon Houlding arrived in Canada via Zimbabwe and South Africa in 1976. He founded Lynx Geosystems and for the next 20 years focused on development and application of 3D modeling technology for mineral deposit evaluation for the mining industry. This technology was the forerunner of much of the mineral deposit evaluation technology that we take for granted today. In 2000 he co-founded EduMine to publish and disseminate online professional development and training to the global mining community, much of which focused on advanced techniques for mineral economics. EduMine provided a platform for promotion of Canadian mining technology and mining excellence around the world and received the strong support of both CIM and SME. Simon Houlding retired in 2017 and lives in Vancouver, British Columbia.
