Unions to strike at Chile’s Chuquicamata after labor deal falls through

Shares in Ivanhoe mines closed up just over 5% in Toronto on Monday outperforming the broader market and bringing the counter's gains to 23.2% over the last week.

Ollanta Humala, President-elect of Peru, fulfilled a campaign promise Thursday in announcing his government's intention to hit mining companies with higher royalty taxes. Humala, who was elected in July, campaigned on a promise to tax mining company profits and distribute them to the poor — a development that had investors and mining company CEOs running for cover in a country that is the world's second largest producer of copper and the sixth biggest gold miner. Companies now pay between 1% and 3% in royalties.

Reuters reports 50,000 protesters battled police in Chile's capital on Thursday, the second day of a two-day strike against unpopular President Sebastian Pinera. A recent poll put the right-wing leader's approval rating at only 26%, below even that of dictator General Pinochet, who ruled the country for 17 years from 1973. The protests follows recent strikes in the copper sector over pay and a campaign against a massive coal mine on an island in Patagonia amid accusations that billionaire Pinera’s shareholding in the developer, Copec, constitutes a serious conflict of interest.
