Cathy M. Hamel

Senior Petrographer B.Sc., M.Sc. (1985), P.Geo.

Senior Petrographer for Vancouver Petrographics with solid working knowledge of volcanogenic massive sulfide deposits, porphyry Cu-Au deposits, PGE, and Sedex deposits.

  • 25+ years of petrographic experience in the evaluation of igneous and metamorphic rocks as well as sandstone, carbonate, and mudstone reservoir systems in Canada [Western Canadian Sedimentary Basin, Beaufort-McKenzie Basin, Eastern Canada including offshore Newfoundland (Orphan, Flemish Pass, Jeanne d'Arc Basins), Labrador Shelf & the Scotian Margin], South America (Columbia, Argentina, Brazil), Africa (Egypt, Chad), Mexico (PEMEX) and the United States (Gulf of Mexico).​

  • Extensive field lithological/structural mapping of the Circum-Ungava meta-sedimentary belt, Cape Smith volcanic-meta-sedimentary foldbelt (Ni-Cu-Co, Pt-Pd) and the Abitibi Greenstone Belt.  Implemented mapping and surface drilling program to determine the extension of The Lac Short gold deposit (Matagami-Chibougamau belt).
