Acero-Martin Appoints Chief Geologist for Pinaya Gold-Copper Project, Peru

April 17, 2008

Dr. Stewart Jackson, President and CEO of Acero-Martin Exploration Inc. (the “Company” or “Acero-Martin”) is pleased to announce that the Company has hired Mr. John Romero as Chief Geologist for its Pinaya project in southern Peru.  Mr. Romero is an accomplished geological engineer with over 15 years experience and a successful track record of advancing key mineral projects in Peru  

Most recently, Mr. Romero was the Project Manager at Silver Standard Resources’ San Luis project in central Peru where he was responsible for guiding the exploration program, evaluating and interpreting geologic data, and coordinating community relations efforts.  Under Mr. Romero’s leadership an initial NI 43-101 compliant resource estimate was produced for the project and the deposit was advanced towards feasibility.

Prior to joining Silver Standard, Mr. Romero was Senior Geologist at the Toromocho project for Peru Copper Inc.  During his four year tenure at Toromocho, John oversaw more than 130,000 meters of drilling and helped contribute to the understanding, definition, and expansion of the deposits at the project.  In 2007, the Aluminum Corporation of China announced a friendly take-over bid to acquire Peru Copper. 

Mr. Romero’s background also includes positions at a number of other senior mining companies with operations in Peru, including six years with Anglo American Exploration Peru S.A.  Concurrent with Mr. Romero’s appointment as Chief Geologist, Mr. Cary Pothorin has stepped down as Vice President of Exploration.  The Company wishes to thank Mr. Pothorin for his contributions to the Company and the advancement of the Pinaya project.

In September of 2006, based on the first 70 holes drilled, an initial independently calculated NI 43-101 resource estimate was reported.  It stated 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 category.

As of March 2008, the Company has completed an additional 79 holes bringing the project totals 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.  Acero-Martin trades on the TSX-Venture exchange under the symbol ASD and the Frankfurt stock exchange under the symbol AMX.
