 A public controversy around this erupted in January 2010, when a North Korean ship carrying 2,800 metric tons of magnetite ran aground near Claveria, Cagayan on New Year's Day.There were claims that the magnetite had been illegally mined in violation of a provincial ban, but others claimed that the quantity in question was just a "sample" and came from a pre-existing stockpile.Some reports claimed that the ship also carried marijuana and shabu, but an immigration officer was quoted as stating the materials in question were just butter and tea.
