Acero-Martin Exploration Inc.: New Gold-Silver Zone Intersected at Pinaya's Montana de Cobre

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 16, 2006) - Acero-Martin Exploration Inc. (the "Company") (TSX VENTURE:ASD)(FWB:AMX) is pleased to provide the following update on its ongoing 10,000 meter (32,800 feet) 2006 drill program at the Pinaya Project in southern Peru. The Company is in receipt of results for four diamond drill holes completed at Montana de Cobre (PDH-038, 040, 041 and 043), which is located approximately 2.5 kilometers north of the Open Pit gold oxide skarn zone ("GOSZ"); and one diamond drill hole (PDH-042) completed at the Western Porphyry Zone (herein "WPZ"). To-date, approximately 4500 meters in 23 holes (PDH-25 to PDH-47 in progress) has been completed.

At the Montana de Cobre Zone (herein "MC"), The gold-silver zone intersected in Hole PDH-41 averaged 46.85 m (153.7 feet) of 0.79 g/t Au and 28 g/t Ag which includes 17 meters(56 ft) of 1.72 g/t Au and 71 g/t Ag. The gold zone intersected in Hole PDH-43 averaged 56.50 meters (185 feet) of 1.12 g/t Au which includes 8.50 meters (27.9 ft) of 5.45 g/t Au. Holes PDH-41 and PDH-43 are both situated along the east flank of Montana de Cobre, and are spaced approximately 200 meters apart.

To date, drilling at the MC has demonstrated significant near surface gold mineralization. The MC consists of a series of drill intersections, soil geochemical anomalies, and trench intersections with significant gold mineralization within a target area that measures at least 650 by 400 meters. Drill holes PDH-38 and PDH-40 were collared near the top of the ridge in an area of northwesterly and easterly trending cross faults. Hole PDH-40 was collared 122 meters east-northeast of PDH-38. Holes PDH-41 and 43 were collared 142 meters east and 118 meters north of PDH-40. These holes intersected more continuous gold mineralization and were drilled in an area that of rock grab samples from historic workings that range from 8.32 to 18.56 gpt Au. Hole PDH-45 was drilled 223 meters to the northwest of PDH-43. Results for hole PDH-45 are pending.

Hole PDH-42, located near the southern end of the WPZ returned 43.50 meters with 0.63 g/t Au and 0.97 per cent Cu. Overlying the copper-gold zone, PDH-42 intersected a leached zone returning 0.29 g/t Au over 45.50 meters (149.24 feet). Drilling of the WPZ continues to show a significant near surface gold component, in addition to high grades of copper mineralization, over an extensive area that is presently being in-filled on 50 meter drill centers. Hole PDH-42 lies 50 meters southwest of PDH-21, which previously returned 63.0 meters (206.6 feet) of 0.66 g/t Au. It is also proximal to an untested ridge that is strongly anomalous with copper and gold in soils, over an area measuring 300 x 250 meters.

The Company is in receipt of the assays for PDH-038,040,041,042 and 043, the results of which are summarized below.

The Company is compliant under National Instrument 43-101 for the Pinaya project, and independent consultants are supervising the quality control and quality assurance program. Core samples are transported to SGS Labs (a laboratory certified by ISO 9002) in Lima, Peru. Gold values are determined by 30-gram fire assay fusion with an atomic absorption spectroscopy finish. All samples are also analyzed for 35 elements by ICP and total digestion and those samples anomalous in copper are reanalyzed by atomic absorption (four-acid digestion). A quality control program of standards, blanks and duplicates is maintained. Jeffrey Reeder, P Geo, is the qualified person responsible for the exploration program at Pinaya.

The Company also announces that it has paid $860,000 US according to its option agreement to acquire a 100% ownership in the Pinaya project. A total of $1,400,000 US has been paid to-date. The final payment of $1.1 M US is due in May 2007 after which the Company will own 100% of the property.
