What does a small town in Sardinia, Italy have in common with the pitched battle over the proposed Rosemont Copper mine in the Santa Rita Mountains south of Tucson?

Watch Cyanide Beach, an explosive new documentary from award-winning investigative journalist John Dougherty, that exposes the Canadian mining speculators who are behind a proposal to open the massive Rosemont Copper mine just outside Tucson, Arizona.

The revealing 24-minute film chronicles the deceptive business tactics of top executives at Augusta Resource Corporation – owner of Rosemont Copper – when they owned and operated an open-pit gold mine in Sardinia Italy from 2003-2007. You’ll see how they left behind a trail of unpaid vendors, a misspent government loan, hidden investors, and a toxic mess known to locals as “Cyanide Beach.”
