Residents of the Tambo Valley, at the heart of the feared impact of the Southern Peru Copper project known as Tía María, are demanding that their local mayors declare their positions vis-à-vis the project. A meeting is to be held on 12 September at which local mayors will be challenged to make clear their views. The president of the Board of Workers of Tambo Valley argues that the company has no municipal operating licence and therefore cannot re-open. http://www.peruthisweek.com/news-tia-maria-protests-in-islay-continue-107505
