Copper futures for March delivery advanced 2.8 percent to settle at $US3.513 a pound at 1:16 p.m. on the Comex in New York, the biggest gain for a most-active contract since Nov. 30.

Purchases by China still posted a drop last year, the first decline since 2008. Futures dropped 23 percent in 2011.

China's policy makers probably will ease real-estate curbs as early as the middle of the year to prevent a collapse of the housing market, according to UBS AG. Construction accounts for a quarter of demand for copper, used in pipes and wiring, the Copper Development Association says.

On the London Metal Exchange, copper for delivery in three months rose 3.3 percent to $US7,740 a metric ton ($US3.51 a pound).

2012 Best Investments: Copper, According to Shayne Heffernan Copper will see $5.15 in 2012 after having a lacklustre second half of 2011.

Heffernan Capital Management research indicates Copper is a viable inflation hedge and will have more upside than many other commodities.

Many people invest in precious metal commodities such as gold and silver but not everyone considers non-precious base metals like copper and nickel.

Unlike precious metals, the prices of base metals are more related to the health of an economy and currency than emotion or world events.

Copper will rally on fundamentals, the supply of copper is very tight across the world. Demand will exceed supply by significant margins within the next year, especially when massive reconstruction activities are proceeding in Japan and several infrastructure projects are progressing in developing regions like India, China and ASEAN.

The International Copper Study Group has said that the growth in copper demand in the world is likely to exceed global output within thia yeas year.

The copper market is facing some severe shortages that should help drive prices to new record highs. Barclays Capital sees the copper market in a 700,000 metric ton deficit in 2011.

Add to that some global strike action at various mines and a perfect storm is forming for copper prices.

Workers at Codelco in Chile, the world's largest copper producer, are set to strike for 24 hours staring on Monday to protest an overhaul of the country's giant state mining company.

A strike for higher pay has paralyzed production at Freeport McMoRan's copper and gold mine in Papua is just part of a global disruption in supply.

A series of bad-weather related events and industrial action has put strain on a market in 2011 that will lead to more demand in 2012.

Political and social upheaval play a significant part in the fortunes of copper miners, but producers of the red metal have been particularly wary of strikes across the globe in recent months. How and whether global corporations are able to resolve labor disputes will be closely monitored not just by their shareholders, but by local governments, international non-profit organizations, and human rights activists, especially as resource nationalism intensifies.

Earlier this month, copper giant Freeport-McMoRanCopper&Gold (NYSE:FCX) was able to reach an agreement with workers, who had been on strike for three months, at its Grasberg mine in Indonesia, the world's second-largest copper mine. Workers protested against low pay and poor working conditions, and only stopped after the Phoenix, Arizona-based company agreed to a 37 percent pay increase over a two year period. In the meantime, however, the company has had to halt production since September, and Freeport's fourth quarter sales projection have been lowered to 800 million pounds of copper compared to its October estimate of 915 million pounds for the same period as a direct result of the strikes.

In September the strikes also disrupted output at a Peruvian mine that is majority-owned by Freeport-McMoRan as workers of Sociedad Minera Cerro Verde also demanded higher wages. Strikes continued for two months without resolution between the workers and the company, but miners went back to work after receiving guarantees that the regional government of Arequipa would unilaterally come up with agreements for improved pay on their behalf, as the government of President Ollanta Humala declared the strikes legal for the first time in the mine's 40-year history.

A growing sense of injustice among mine workers as well as frustration among the general population that the wealth of natural resources not being shared equitably is far from unique among Freeport-McMoRan's workers.

Xstrata (LSE:XTA) and Anglo American (LSE:AAL) faced the wrath of union workers last month as they protested against possible layoffs at the Collahuasi mine in Chile which ended November 30 when the company laid off 32 employees instead of 62 as initially planned. Both Xstrata and Anglo American have a 44 percent stake in the mine, while Japanese trading house Mitsui (TSE:8031) holds the remaining shares in the site which produces about 3 percent of the world's total copper supply.

China too is facing greater scrutiny for its labor practices in overseas mines, with Human Rights Watch going on the offensive over its treatment of workers at Zambia's copper mines. In early November, the advocacy group released a report stating that the four mines in the African nation operated by state-owned China Nonferrous Metal Mining Group routinely flout labor laws and regulations.

Strikes across the globe have had a direct impact on the price of copper, and coupled with the technology to broadcast their grievances to a global audience, mine workers have been able to rally greater global support for their cause. Indeed, Indonesia's Grasberg union spokesman Juli Parorrongan stated that even as Freeport-McMoRan agreed to the pay increases, this is the first page of the struggle, and not the end, suggesting that workers in other sectors across the country as well mine workers worldwide will demand greater equity for their work.

Despite such labor tensions, however, the continued imbalance in supply over demand worldwide should keep producers eager to remain in business despite the growing challenges of meeting workers' needs as well as government regulations and environmentalists' demands. Certainly, the 25 percent decline in output at the world's largest copper mine in Chile's Escondida mine operated by BHP Billiton (ASX:BHP) as a result of strikes and bad weather is keeping supply tight, as well as a fall in copper stockpile in China, are also expected to keep the price of the red metal high despite the continued sluggishness in the global economy.

It is clear nonetheless that moving forward, junior mining companies too will need to be increasingly more vigilant about political risk and labor relations as well as commodity prices in calculating returns on their investments.
