There are growing concerns about financial donations from mining companies to Canadian university campuses. University faculties in Argentina have also been rejecting such corporate blandishments. In March 2011, the Faculty of Philosophy and Letters at  Argentina’s National University of Tucumán became the twenty-seventh academic faculty to reject funds from the Alumbrera Mining company. Goldcorp has a 37.5% share in Alumbrera, which is operated as a joint venture with London-listed Xstrata and Toronto-based Yamana Gold. It was Goldcorp’s biggest source of earnings outside of Canada in 2010.
