(IDEX Online) - Workers at the Diavik diamond mine, close to the Arctic circle, were surprised to find a grizzly bear prowling the cafeteria.It's not clear how the animal gained access to the site, at Lac de Gras, in Northwest Territories, Canada, but staff suspect it entered through external doors to the adjoining kitchen.A picture of the bear was posted on Facebook, captioned: "This is wild!!!!!"."Diavik can confirm a bear entered its main camp on September 13," said the company in a brief statement. It is understood that neither the bear nor any workers at the mine, operated by Rio Tinto, were hurt.
