Planning Advisory. Based on his extensive experience in mine optimization and strategic planning, David Whittle can provide services in the following areas:
Whittle (1990) incorporated a method into pit optimisation software that takes into account the value that ore has if mined by an underground method. Consider a case in which some blocks can be mined by either the openpit or underground methods.
Years of open pit mine production results in a pit of increased width and depth. This causes the cost of producing deeper ore to increase. The ore produced can also be more heavily diluted by surrounding waste. In order to increase the amount of economic reserves and mine life, a transition to underground mining can be made. There is a threshold where mining through underground methods becomes ...
and pit optimization is determined by Whittle 4X. New developments include the introduction of a linear programming ... reached final pit boundaries. The LP works on the principle that if a block is to be mined, the nine blocks above it must also be mined. Since only blocks inside the final pit layout

Jeff Whittle was the originator of what is now the GEOVIA software, as well as being the author of Prober E. Currently, there are over 2,000 Geovia Whittle software licenses in use by mining, exploration, consultant and academic customers around the world.
Project Type: Openpit / underground potential Project Status : Feasibility Minago, one of Canada's largest undeveloped sulphide nickel deposits, is located 225 kilometres south of Thompson, Manitoba and owned by Victory Nickel Inc. ("Victory Nickel" or the "Company").
The Whittle Enterprise Optimisation model is tailored for each site. It determines how much capital is worth spending on each constraint, simultaneously rebalancing the pit, phase, schedule, cutoff, blending, stockpile, processing, product mix and logistics
This book presents a collection of papers on topics in the field of strategic mine planning, including orebody modeling, mineplanning optimization and the optimization of mining complexes.

Pit Optimization – How I View It Date: June 3, 2015 Author: Ken Kuchling One of the first steps in open pit mine design is the completion of a pit optimization analysis. Pit optimisation is used to define the most profitable pit shell (or nested pit shells) for a given set of economic parameters.
