Professor Gema R. Olivo (Ph.D., P.Eng.) has been working since 1999 at Queen’s University, after completion of her post-doctoral research at McGill University, Canada, and working as exploration geologists for major and junior companies.  She received her B.Sc. in Geology and M.Sc.  in Mineral Exploration from Universidade de BrasĂ­lia, Brazil, and Ph.D. from UniversitĂ© du QuĂ©bec Ă  MontrĂ©al, Canada. She has more than 30 years of experience working in academic research on mineral deposits and on mineral exploration projects in Brazil, Chile, Peru, Mexico, USA and Canada among others. In 2003 she was granted the Premier's Research Excellence Award for her research on Hydrothermal Gold Deposits, has been associate editor to Canadian Mineralogist, and reviewer for major journals, was member of the NSERC Strategic Grant committee on Natural Resources, Chair of NSERC Alliance Missions committee, and Co-leader of the NSERC-CIMIC Footprint project, among others.  She has supervised more than 60 graduate students since 1999, with research results published in major international journals. She has been fortunate to work with many talented graduate students and post-doctoral fellows, some of them being recipients of major national and international awards and working in very prestigious positions in academia, government and industry around the world.

Research Interests/Current Research

Her research goals are mainly to understand the mechanisms by which metals are stored, have migrated and have been concentrated in anomalous amounts in the upper crust to form mineral deposits. These objectives are achieved by applying a multidisciplinary approach, and the applications of the knowledge generated by this research program are aimed at helping to improve exploration strategies and minimize the costs of mineral exploration. Her research has been focused on precious metal deposits and districts (gold, silver and platinum-group elements) in volcanic-plutonic and sedimentary sequences and base metals in mafic-ultramafic and metasedimentary systems in various geological settings in Canada, Brazil, USA, Mexico, New Zealand, Peru and Argentina, among others. She has also collaborated in the investigation of a variety of other mineral deposits around the world, including: uranium deposits associated with unconformities in the Athabasca basin and its basement, Canada (Eagle Point, Millennium deposits, and Wheeler River alteration system); Zr, and REE deposits in South Africa (Pilanesberg Project) and New Mexico (Gallinas Deposit); Ag-rich epithermal-type prospects in Peru (Santo Toribio and Pozo Rico) and Argentina (Navidad); and VMS prospects in Dominican Republic (San Antonio Concession) and deposits in Canada (Kidd Creek, Ontario and High Lake, Nunavut); tin deposit in greisen systems in Central Brazil (Mangabeira); gold deposits related to intrusions in Cuba (La Union prospect).

Supervising Information

She has supervised more than 60 graduate students since 1999, with research results published in major international journals. She has been fortunate to work with many talented graduate students and post-doctoral fellows, some of them being recipients of major national and international awards and working in very prestigious positions in academia, government and industry around the world. Her current projects involve field, laboratory and modelling research to understand the processes related to Ni-Cu-PGE in mafic-ultramafic sequences and base metals in metasedimentary systems.
