"In January, we said our plan was to divest our minority interest in the Tarkwa and Damang mines for proceeds in excess of $600 million and by the end of June we had closed the sale for gross proceeds of $667 million. During that period, we also confirmed a near 700% increase in mineral resources at our niobium mine and increased our dividend by 150," said Steve Letwin, IAMGOLD's President and CEO.

Despite a report on Wednesday showing a surge in July, China's copper imports were still down 22% in the first seven months, suggesting slowing demand in the world's top copper consumer is adding to concerns that shaky western economies will knock prices further. However, according to a new study by Canaccord the copper mining industry is operating under 'a high degree of stress' and called robust copper prices the 'new normal' thanks to supply shortages. More than 500,000 tonnes of production have been lost this year due to weather delays, poor deposit grades, worker strikes and mill problems, mostly in Chile, the world's number one producer.

Dow Jones reports resource nationalism is the top business risk for the top 30 global miners, while supply capacity constraints ranging from skills shortage to infrastructure bottlenecks continue to dominate the top ten list, according to an annual survey by consultants Ernst & Young. Resource nationalism jumped to the top of the list this year from fourth in 2010 after 25 countries announced their intentions to increase their take of the mining industry's profits and others contemplate outright nationalization. Fraud, bribery and corruption sneaked onto the list of top concerns for the first time as a number of countries introduce or tighten rules for executives operating in countries that rank high on corruption indices.

Copper prices may remain above $4 a pound in coming months, driven by a recovery in demand from China, according to Codelco, the world's largest producer. Chinese inventories seem to have decreased and now the industry is catching up again," Diego Hernandez, chief executive officer of the Chilean state-owned company, said in an interview on Bloomberg Television. Output from Chile, the world's largest copper producer, may miss a target of 5.6 million metric tons in 2011 by 5 percent because of project delays, weather disruption and strikes at mine sites. Codelco plans to spend about $20 billion this decade to boost annual production to meet forecast rising global demand for copper.
