Copper

Output of copper cathodes and copper concentrates are beginning to be affected by a work stoppage that began Monday at the giant Collahuasi copper mine in Chile. Reuters reports that the mine, jointly owned by Xstrata and Anglo American, has implemented a contingency plan to deal with the labour action, which about 10% of workers are participating in: Some workers in Collahuasi, which produces about 3 percent of the world's copper, downed tools on Monday over fears of coming layoffs. The company later on Monday announced it had laid off a "limited" number of workers in response to a partial one-day strike in October, a move that could stoke tensions between management and the union.

A potential copper-nickel mine in Michigan's Upper Peninsula had a roadblock removed recently with a judge's decision to uphold the mine permits.

The permits had been challenged in court by groups concerned about acid mine drainage including the National Wildlife Federation.

For the third time this year, workers at the Collahuasi mine in Chile are on strike. The union representing the world's third largest copper mine is accusing management of reneging on agreements that ended a work stoppage in October, AFP reports. Production was paralyzed on July 30 and October 29 when workers downed tools. Collahuasi is owned by Switzerland’s Xstrata and Britain-based Anglo American. Reuters reports Collahuasi produced 504,000 tonnes of copper in 2010, when output was hit by a month-long strike. The mine expects to produce 500,000 tonnes of copper this year. It supplies roughly 3% of the world’s copper.

The Pebble Mine copper-gold-moly project in Southwestern Alaska got hit with another negative poll last week. The Huffington Post reports that 81% of the roughly 2000 shareholders of the Bristol Bay Native Corporation — the regional Native corporation and largest private landholder in southwest Alaska — have rejected the mine on the basis that it will "unavoidably put at risk the 'fisheries and our Native way of life.'" The project is a partnership between Anglo American (LON:AAL) and Northern Dynasty Minerals (NYSEAMEX:NAK).

Latin American blogs reported on Sunday exit roads from the regional capital remained blocked and anger was mounting over Newmont Mining's proposed $4.8 billion Conga gold mine in northern Peru as protests entered its fourth day. Schools and business had closed and police used teargas against marchers since protests began Thursday. Residents led by the Maoist president of the Cajamarca region say Conga will destroy the environment by transforming four high Andean lakes into reservoirs for mining operations and on Saturday formed the 'Front for the Defence of the Interests of Cajamarca'. Conga would be the biggest investment ever in Peru mining and is a crucial test for newly installed president Ollanta Humala who has on many occasions publicly backed the project.
