- Multiple rock types with hard and soft boundaries
- Multivariate simulation of any number of variables
Postprocessing and Optimization
- Recoverable reserves calculation
- Resource/reserve classification
- Dig limit optimization
The Place for Pangeos
There is a number of general mine planning (GMP) software packages on the market. GMP software is well-suited to data management, conventional geologic modeling, visualization, and mine planning tasks. There is a number of specialized geostatistics software packages on the market; however, there are no geostatistical software packages that provide a satisfactory solution to the problems of (1) reliably generating geostatistical realizations of multiple variables within multiple rock types, and (2) providing optimized solutions to reserve estimation and grade control in presence of uncertainty quantified by multiple geostatistical realizations. Pangeos meets the need for focused mining geosta- tistics simulation and optimization software.
