A commercially viable, statistically validated analytical method was developed to fulfill the major objective of this research: to identify the physical, chemical and biological links between hydrocarbon abundances on the surface with the buried footprints of economic mineralization. Hydrocarbon responses were tested over epithermal Au-Ag-Cu and porphyry Cu-Mo deposits in British Columbia.
With this newly developed approach, B horizon soil samples were subjected to solid phase microextraction and analysed by GC-FID to determine organic compound concentrations. Results show anomalous responses in soils overlying and adjacent to known mineralization. Discrete geochemical responses to the deposits footprint, changes in lithology, and cross-cutting faults demonstrate the predictive capabilities of this technique.
