Reuters reports Peru's mining firms have agreed to pay higher royalties in an overhaul of the current system, sources on both sides of negotiations between companies and leftist President Ollanta Humala's government said on Tuesday. Under the new system, companies would pay royalties based on their operating profits, not sales and will be be similar to the system used in Chile. The new royalties rates still need to be defined, but they would likely be higher than the current rates of 1% – 3% charged on sales. The initiative comes as mining companies in Peru plan to invest $42.5 billion over the next decade, mainly in copper and gold projects. Peru is the world's largest miner of silver and the second-largest miner of copper.

Barrick Gold Corp. closed down slightly and outperformed a weak broader market on Tuesday despite a downgrade from CIBC World Markets, which is advising investors to remain cautious as the miner diversifies into copper.

Zinc price gains in July were more than wiped out in early August as worries intensified about global economic prospects, and further price declines could trigger mine production cuts in China, and help reduce surplus supply. "If prices fall below $2,000 then we would expect a lot of Chinese mine production to stop," said Giles Lloyd of industry consultants CRU Group. In 2010, China mined 3.7 million tonnes of zinc, accounting for 30 percent of world mine output.
