Dr. Catchpole has extensive experience working in Mexico, USA, Canada, Andean South America and Europe, mainly with porphyry Cu, skarn (Zn-Pb-Ag-Cu), epithermal precious (Au-Ag) and base metal (Ag-Zn-Pb-Cu) deposits. Dr. Catchpole has worked in project generation, exploration and project evaluation of precious metal and porphyry Cu projects for Teck Resources Limited (“Teck”), Vale Exploration Canada and Sumitomo Metal Mining Canada. Dr. Catchpole has been directly involved in designing, planning and executing drill programs, as well as managing greenfield and reconnaissance stage projects in Mexico. Dr. Catchpole comes to GR Silver Mining from Teck where he was project manager and geoscience lead at the San Nicolas VHMS deposit in Zacatecas, Mexico, currently at pre-feasibility stage. His background in geologic, alteration and structural mapping (surface and underground) in Andean volcanic arc settings with good understanding of hydrothermal alteration and mineralization is a valuable addition to the GR Silver Mining exploration team.
