About Acero-Martin Exploration Inc.

Acero Martin's 100%-owned Pinaya project hosts one of Peru's newest and richest copper-gold porphyry/skarn deposits. The project is located 110 km northeast of Arequipa and approximately 60 kilometers south of Xstrata's Tintaya copper-gold mine, and is favoured with excellent nearby mining infrastructure.

In September of 2006, based on the first 70 holes drilled, an initial independently calculated NI 43-101 resource estimated that Pinaya hosts an Indicated Resource of 29.13 million tonnes grading 0.53 g/t gold and 0.42% copper and an Inferred Resource of 12.72 million tonnes grading 0.41 g/t gold and 0.41% copper. This equates to approximately 498,000 troy ounces of gold and 269,000,000 pounds of copper in the Indicated category, and 168,000 troy ounces of gold and 115,000,000 pounds of copper in the Inferred.

As of February 2008, the Company has completed an additional 79 holes bringing the project total to 40,900 meters and 149 holes. Drilling since the release of the initial resource continues to work to expand the size of the deposit and test new zones of mineralization. Alongside the drilling the company is currently completing a preliminary economic assessment ("scoping study") to determine the potential for, and economic parameters of, developing a starter open pit mining operation. Acero-Martin trades on the TSX-Venture exchange under the symbol ASD and the Frankfurt stock exchange under the symbol AMX.
