Use of Multivariate Geochemical Domains as a Validation Tool in the Classification of Predicted Resource Metal Extraction Recoveries. Fruta Del Norte Gold Deposit, Ecuador, Case Study

Based on a statistical analysis of the categorical and numerical data from the established geological model, a geochemical classification of mineralization has been shown to be objective in nature and correlated to the envisioned metal extraction process. Multivariate chemical classification has the potential to discriminate within a combined response from different types of alteration and metal abundances. Distinct domains of chemical response determined by clustering analysis were used as a validating criterion for a geologically driven metallurgical testing program. The groups established are spatially linked to the geological process responsible for their genesis, providing clarity in geometallurgical and resource modeling.
