文摘

Risk assessment of spatial uncertainty in attributes of mineral deposits in a large and geologically complex case study. Risk quantification in grade-tonnage curves and in-situ mineral resources or ore reserves. Step by step geostatistical simulation of zone boundaries and multiple elements, from data analysis to validation. Computationally very efficient simulation methods for routine use in industrial environments. Methods and workflow are applicable to geotechnical and rock mass spatially distributed properties of rocks.
