Aluminum Corp. of China (aka Chinalco)
After a big drop in earnings last year, Chinese aluminum giant Chinalco is already witnessing a rebound in Chinese aluminum prices because of government stimulus measures and a recovery in demand.

In the weakened commodity markets, the Chinese have been taking advantage of depressed prices to prepare for future increased commodities demand with strategic investments around the world. A pending deal with Rio Tinto is expected to expand Chinalco's investment in commodities, adding to the stake that it took with Alcoa (NYSE:AA) in Rio Tinto last year.

The latest deal is backed by cheap financing and is expected to provide strong returns. The $21 billion in financing for the deal is being arranged by China Development Bank. The initial rate on the loan is less than one-third of the 9.25% coupon that Rio Tinto will pay Chinalco on $7.2 billion of convertible bonds.

More than 96% of the 3,553 CAPS members rating Aluminum Corp. of China expect it to outperform the market.

Cameco
Canadian uranium miner Cameco pulled in record revenue of $2.3 billion in 2008. While the mining industry has scaled back operations and production, Cameco remains confidently focused on long-term strategies. It has inked long-term contracts with stable electrical utilities that maintain high capacity during tough times, helping the company ride out volatility in the spot price market.

Many CAPS members echo the company's expectations for the industry's future and expect significant nuclear energy growth over the next decade in China, India, and even smaller countries such as Sweden. While uranium provider USEC (NYSE:USU) has been waiting for U.S. government help to move forward with a new project, a canceled uranium mining ban in western Australia has paved the way for exploration at Cameco's mine, which was purchased from Rio Tinto last year.

CAPS members have long been big fans of Cameco, with 97% of the 1,398 members rating the company today believing it will beat the market.

Yamana Gold
Canadian-based miner Yamana Gold generated record revenue for 2008, despite a sharp decline in prices for some metals. Similar to Agnico-Eagle Mines (NYSE:AEM), Yamana Gold took a hit from declining copper prices in the fourth quarter, but expects further revenue and earnings growth to come almost entirely from precious metals. Like peer Kinross Gold (NYSE:KGC), Yamana experienced declining production costs in the fourth quarter, and predicts that downward trend to continue, further adding to its margins for gold.

The company plans big production increases in 2009 and beyond, giving nearly 97% of the 3,505 CAPS members rating Yamana Gold reason to be bullish.

Let 130,000 members be the jury
The collective wisdom of a huge pool of investors can help give context to a page of numbers from a stock screen -- but individual investors are still the judge. Fools should always perform their own due diligence.
