Long-Term Planning at Raglan

This paper reviews the Falconbridge- SMRQ?s Raglan project in northern Quebec and the process that was used in developing its current long-term mine plan. Challenges were many and not only limited to the longevity of the project, numerous ore deposits (both underground and open pit), and a 40km property strike length. As a result of its remote northern location other factors such as progressive reclamation, leachable mine waste, water treatment, and waste management were also part of the plan. A combination of modern planning tools were used to formulate the plan including DataMine, Mine 2-4D, AutoMod Simulation, and an Excel based financial spreadsheet to bring the total plan together. The focus of this paper is to show the complexity of modern mine planning and associated economic modeling of mine processes.
