Positive Lab Results Provide Further Confirmation of Champinon Project Potential

CHICAGO, IL--(Marketwire - Aug 6, 2012) - Tara Minerals Corp. (OTCBB: TARM) (BERLIN: 6T3) is pleased to provide results from a metallurgy recovery study conducted by METCON Research, an affiliate of KD engineering, in Tucson, Arizona regarding material from the Champinon Iron Project. The recovery results revealed high levels of recoverable magnetite. Higher levels of magnetite improves opportunity for increased volumes of ore and enhances overall potential project yields.

Test results confirm that a wide range of iron concentrations are technically viable to mine. 
Results also revealed that lower iron ore grades can be concentrated through crushing and magnetic separation to produce a marketable iron grade product. They also confirm that the low- and high-grade ores can be processed together. This increases ore tonnage crushing rates while decreasing stripping ratios, which can significantly enhance project economics.

Steve Eady, Chief Geologist, commented, "I am really excited by these results, because they confirm that we have discovered a significant deposit for iron ore mining and production. The results have provided information that can assist us in optimizing the project potential."

"In addition to confirming much of the work that has already been done, these results provide information needed to complete the initial mining plan and plant design necessary to begin producing salable Iron Ore at our Champinon Iron Project. As we rapidly advance towards production, we look forward to continually communicating the company's progress to our shareholders," said Francis R. Biscan, Chief Executive Officer.

Initial head grades of 52% and 41% were used for the study. The magnetic concentrates had final total iron grades of 68% and 58% respectively at a 4 mesh grind size. At a 10 mesh grind size, the samples had final concentrate iron grades of 68% and 67%.
