10 tousand people protest against mine Cerro Verde, next to Arequipa.

Article at Servindi, but just in Spanish: » Perú: Diez mil pobladores protestaron contra minera Cerro Verde .
Cerro Verde is a copper mine and one of the shareholders is Buenaventura which holds shares on Yanacocha, Cajamarca.

Up to now, I couldn´t see new about this protest in the financial-mining-gold stocks news. Usually the stocks react very sensible with protests like this.
