Peru gives Southern Copper construction permit on delayed $1.4bn project

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.

Brazilian mining conglomerate Vale, the world's leading iron producer, reduced its spending budget by 11 percent for 2012 in the face of an uncertain outlook for the global economy and commodities prices. In a statement released today, the Rio de Janeiro-based company plans to invest $21.4 billion on mining projects next year after failing to meet spending targets in 2011.

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.

Latin American Herald Tribune reports Venezuela's first shipment of 160 – 180 tonnes of gold held abroad was received at Maiquetia International Airport outside Caracas on Friday night. In operation that also involved tanks and aircraft, the first of some 15,000 standard 400-ounce bars wrapped in black plastic inside a caravan of armoured vehicles escorted by 500 soldiers then made its way to the bank’s headquarters downtown. President Hugo Chavez announced in August that the South American country plans to repatriate its gold reserves held by banks in England, the US, Canada and France. The Central Bank of Venezuela already holds 154 tons of bullion domestically.

Reuters reports schools and businesses were closed and Peruvian police fired tear gas on Friday to break up a protest at Newmont Mining and Buenaventura's proposed $4.8 billion Conga gold mine as the government tried to mediate a bitter environmental dispute over the project. Residents in the northern city of Cajamarca which has more than 200,000 residents (pictured), led by the president of the region,  say a new mine – adjacent to South America’s largest gold mine Yanacocha – will harm agriculture and livestock by relocating water supplies.  Conga would be the biggest investment ever in Peru mining.

Brazil has temporarily banned Chevron from drilling in the country after it caused an oil spill off the coast of Rio de Janeiro, raising doubts about the company’s role in one of the industry’s biggest investment programmes. Late on Wednesday, Brazil’s National Petroleum Agency (ANP) accused the U.S. company of negligence late on Wednesday, announcing it would suspend all of Chevron’s drilling until it clarified the reasons for a spill that released almost 3,000 barrels of oil into the sea earlier this month. Analysts believe that the Brazilian government is keen to make an example of Chevron as a warning to other foreign companies looking to take a share of Brazil’s pre-salt reserves, which are estimated to contain as much as 50bn barrels of oil.

Peru's government urged opponents of Newmont Mining's proposed $4.8 billion Conga gold mine project to refrain from violence during a protest scheduled for today as President Ollanta Humala scrambles to solve the bitter dispute.

Fears over the direction of Vale, the world’s biggest miner of iron ore by volume, renewed this morning as the company’s CEO Murilo Ferreira announced late on Monday that he will submit to the Board of Directors a proposal for a new structure of the Executive Board. Investors have been particularly cautious of management changes at the miner since Brazil’s government helped push out Roger Agnelli, Vale’s former chief executive, at the end of his mandate in May. The company said that the restructuring aims to establish an operational model with clearly defined roles and responsibilities for each business unit.

They were supposed to be the vessels that will ferry iron ore from the world's largest exporter to the world's largest customer of the crucial steelmaking ingredient. Instead, Vale's new fleet of iron ore carriers could remain moored at home docks because the Chinese don't want them. Bloomberg reports that the Vale Brasil, the largest bulk carrier ever built, was designed to carry iron ore to China from Vale's mines in South America, but it has not made one voyage in six months of operation. The reason? China is refusing to accept the vessel, which is part of a fleet of 19 ships that Vale is buying from Chinese and Korean shipbuilders in deals valued at $2.3 billion.
