Acero-Martin Reports: Trench Results Continue to Expand the Pinaya Gold-Copper Project in Southern Peru

Acero-Martin Exploration Inc. (the “Company”) is pleased to announce a summary of the results from its 2006 trenching program at the Pinaya project in southern Peru. The 2006 program consisted of 46 trenches for a total of approximately 6.4 kilometers of exposure. Within those trenches 4287 channel samples with an average width of 1.5 meters were collected and sent to SGS Laboratories in Lima, Peru for analysis.

The objective of the 2006 program was to test several prospective areas along the two parallel northwest-southeast trending belts known to exist on the property; the main resource belt and the relatively untested eastern belt. Please see
http://www.aceromartinexp.com/asdtrenching06.pdf for a detailed map.

The main resource belt includes the Western Porphyry and Gold Oxide Skarn Zone resource areas and contains both porphyry copper-gold and structurally controlled copper-gold mineralization. The belt currently forms a mineralized zone approximately 2.5 kilometers long and up to 500 meters wide and is open to the northwest and southeast.

The latest trenching results indicate that the belt holds excellent potential to be extended to the northwest and southeast. Positive trenching results were obtained from both the northwest (Cerro Antaña zone) and southeast (Viscachani zone) ends of the belt.

The following table highlights the significant new trench results.

The second belt tested by trenching, the eastern belt, is located approximately one kilometer to the east of the previous and, from northwest to southeast, includes the Montaña de Cobre, Minas Jorge, and Don Pedro zones. These zones appear to be along strike from each other, and form northwest-southeast trending gold-silver-copper mineralized lenticular structures that are up to approximately 800 meters long and 200 meters wide. Out of the three zones identified in the belt only Montaña de Cobre has been tested by drilling. In 2006, PDH-43 cut 56.50 meters of 1.12 g/t Au at the zone.

The area of mineralization covered by the eastern belt is highly prospective and is potentially larger than the main resource belt to the west. The results of the recent trenching program are positive and highlight the potential of the belt for new discoveries. Positive trench results were received from the Montana de Cobre and Minas Jorge zones. Exploratory drilling on these zones is planned for 2007.

Trenching has proven invaluable for generating high quality drill targets at Pinaya. Due to weathering and leaching of surface rock, gold values over 100 ppb and copper values of over 100 ppm generally indicate the potential for significant subsurface mineralization.

Regarding the recent trench results Donald Gee, President and CEO of Acero-Martin Exploration stated: “The results of previous trenching and drilling programs indicate a strong correlation between surface work and drilling results. The latest trenching results strengthen our belief that we can continue to expand the resource at the main belt and make new discoveries on the adjacent belt to the east.”

The Company is compliant under National Instrument 43-101 for the Pinaya project. Jeffrey Reeder, P.Geo, and Cary Pothorin, P. Geo are the qualified persons responsible for the exploration program at Pinaya and are supervising the quality control and quality assurance program. A quality control program of standards, blanks and duplicates is maintained.
