NEW YORK ( TheStreet) -- MAG Silver ( MVG), GoldCorp ( GG), International Coal Group ( ICO), Puda Coal ( PUDA), Rio Tinto ( RIO), Barrick Gold Corporation ( ABX), Sterlite Industries ( SLT), VALE ( VALE), Companhia Siderurgica Nacional ( SID), Gerdau ( GGB) have an upside of up to 55%, based on analysts' consensus estimates of 12-month price targets.

Demand surge for commodities worldwide ensures upswings in most metal prices. Gold and silver have had a good run, delivering around 27% and 90% returns during the past one year, respectively. Besides, a revival in developed economies like the U.S., and a sustained push from emerging markets, would augur well for mining companies.

We have identified 10 mining stocks that investors can consider for the long term. The selected stocks have potential to deliver a 23% to 55% return in the next year and are from countries like the U.K., China, India, Canada, the U.S. and Brazil. The selected stocks have analysts' buy rating of at least 56%, while Sterlite, Puda and Mag Silver have 100% buy rating. These 10 stocks, on average, registered gains of around 50%-55% during the last year, and analysts foresee further upside from present levels.

The stocks are stacked in terms of upside, great to greatest.

10. Gerdau ( GGB) is an integrated steel player operating in Brazil, North America and Latin America. Gerdau produces common and special long steel and flat steel.

Pursuant to its expansion plans, Gerdau added the remaining stake in Ameristeel to fully own the company in June 2010. In December 2010, Gerdau announced its merger with Acos Villares, a company engaged in the production of long steel. These acquisitions during the past six months will increase Gerdau's exposure in specialty steel.

During the third quarter, higher production costs dented profitability, while net income declined 7%. However, the 14% year-over-year growth in sales volume boosted net revenue by 20%. Production volumes were up 9% during the same period.

The stock gained 2.5% in the last year and is trading at 15.5 times its estimated 2011 earnings.

9. Companhia Siderurgica Nacional ( SID) is an integrated steel producer in Brazil with interests in mining and logistics.

Domestic sales increased in recent quarters. Net sales for the first nine months were up 38%, while the share of exports in overall revenue dipped around 27%, compared to 29% during the same period last year.

The company's efficient cost-containment strategy and lower selling and administrative expenses improved operating margins. EBITDA margin rose 43.1% during the first nine months of 2010, compared to 30% in the prior year.

Analysts are positive about the company's earnings profile, although weaker steel prices and higher capex related to investments in a railroad and securities trading could dampen earnings. Overall, analysts' consensus estimates indicate 30%-35% earnings growth during 2011 and the stock is trading at 11.8 times its estimated 2011 earnings.

8. VALE ( VALE) is a metals and mining giant producing iron ore and iron ore pellets.

Sterlite has a strong balance sheet with cash and cash equivalents of $6 billion, which can be used for organic and inorganic opportunities.

On the operational front, production ramp up at its new smelters will augment volumes. The strong performance of its power and zinc segments could improve its earnings profile.

Commissioning of the Pueblo Viejo and Pascua-Lama projects would improve gold production to 9 million ounces over the next five years. Of the 28 analysts covering the stock, 24 rate it a buy. The stock gained 34% in the last year and is trading at 11.5 times its estimated 2011 earnings.
