Acero-Martin Exploration Inc.: Eight Holes Intersect Significant Gold and Copper Mineralization

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 23, 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 ft) 2006 drill program, at the Pinaya Project in southern Peru.

To date, the 2006 drill program has focused on two areas: the Gold Oxide Skarn Zone (herein "GOSZ") at the Open Pit and the Western Porphyry Zone (herein "WPZ"). Eight diamond core holes (PDH-025 to PDH-032) have been completed within an area measuring approximately 350 m (1,148 ft) north-south, by 600 m (1,968 ft) east-west. All holes have intersected strong gold and copper mineralization.

Significant copper and gold mineralization was intersected at the WPZ and at the GOSZ, along a strike length exceeding 1,250 meters (4,101 ft). The Company is now in receipt of analytical results for holes PDH-025 thru PDH-029 completed during the current 2006 drill program, and remaining results for PDH-024, which was completed during the latter part of 2005.

Highlights are as follows:

Results include PDH-025 which intersected 60.80 m (199.5 ft) of 0.71 g/t Au and 1.18% Cu; PDH-27 which intersected 78.5 m(257.5 ft) of 0.44 g/t Au and 0.36% Cu and PDH-028 which intersected 38.0 m(124.7 ft) of 0.24 g/t Au and 0.87% Cu.

EXTENSION OF THE GOLD OXIDE SKARN ZONE (GOSZ)

Holes PDH-027 and 028, were located approximately 250 m to the southeast of the main open pit, and intersected significant gold and copper values. These holes successfully extended the known gold mineralization at the "GOSZ") by more than 250 meters/820ft to the southeast. The total drill tested strike length of the "GOSZ" is currently 501 meters or 1,644 feet.

Additional details for the 2006 drill holes are as follows:

PDH-025 (225 azimuth at an inclination of -60 degrees to a total depth of 246.0 m) located approximately 52 m southeast of PDH-020, was drilled in an area of strong copper and gold anomalism in soils and nearby trenches.

PDH-026 (225 azimuth at an inclination of -60 degrees to a total depth of 150.70 m) was collared northeast of PDH-6 to test for skarn mineralization. The hole was drilled across a strong near surface IP chargeability anomaly that measures 1.2 km in length and is partly coincident with the gold mineralization at the Open Pit area.

The best results were from 40.0-113.5 m (73.5 m/241 ft) and returned 168 ppb Au (0.17 gpt Au) and 1321 ppm Cu (0.13% Cu). This includes 89.0-101.50 m (12.50 m/41 ft) of 0.07 g/t Au and 0.78% Cu and 101.50-113.5 m (12.0 m/39 ft) of 0.52 g/t Au.

PDH-027: (270 azimuth at an inclination of -50 degrees to a total depth of 101.30 m) was collared approximately 250 meters along strike to the southeast of the Open Pit, in an area of strong copper and gold anomalism in nearby soils and trenches. Best results were from 10.5-89.0 m (78.5 m/259 ft) and returned 0.44 g/t Au and 0.36% Cu.

PDH-028: (270 azimuth at an inclination of -70 degrees to a total depth of 121.05 m) was collared at the same location as PDH-27.

Donald Gee, President said, "These initial eight drill holes are an exciting extension of known gold and copper mineralization. The Gold Oxide Skarn Zone ("GOSZ") identified in the Open Pit area has been extended by more than 250 meters (820 ft) to the south by PDH-027 and 028; total strike length of the GOSZ is now 501 m or 1,644 ft and remains open along strike to the NW and SE. In addition, the Western Porphyry Zone ("WPZ") strike length is now extended to 1.2 Km (3,937 ft) which is still open to the NW and SE. We have confirmed continuing ore grade intersections in the WPZ and GOSZ. These results point to a combined gold/copper resource that is potentially much larger than initially anticipated."

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 International Standards Organization 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, 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. Cary Pothorin P.Geo is the Qualified Person responsible for the exploration program at Pinaya.

Further assay results will be released as they become available.
