Soil Sampling Discovers New Gold-Copper Zones at Acero-Martin's Pinaya Project, Southeastern Peru

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 9, 2007) - Acero-Martin Exploration Inc. (the "Company") (TSX VENTURE:ASD) (FRANKFURT:AMX) is pleased to announce that a recent soil sampling campaign has outlined two new large gold-copper anomalies adjacent and contiguous to the deposit defined in 2006.

In early 2007, the Company started a new geochemical soil survey to cover parts of the Pinaya property that had never been sampled before. The existing soil sample grid (roughly 3 km x 2 km) that covers the Western Porphyry and Gold Oxide Skarn Zones was extended to the northwest by an area of roughly 2 km x 0.8 km, and to the southeast by an area roughly 4 km x 1.4 km. The objective was to extend the grid to cover the northwest and southeast extensions of the Tertiary Puno group, which hosts the known gold-copper mineralization at Pinaya.

A total of 723 soil samples were collected from the new grid areas and analyzed by fire assay for gold and 34 element ICP at SGS Laboratories in Lima, Peru.

The soil sampling in the northwestern grid revealed an anomalous area measuring 2.2 km x 400-600 meters wide. Copper values within the zone ranged up to 56.5 ppm and gold values up to 84 ppb. The anomaly remains open to the north and west.

Soil sampling in southeastern grid also revealed an area approximately 2.8 km x 200-600 meters wide which is strongly anomalous in copper, with values as high as 1212.8 ppm. There is a smaller coincident gold anomaly within this zone, with values as high as 126 ppb Au. The area is notable from a distance with a visible color anomaly containing abundant iron oxides in the soil and remains open to the southeast.

The zone of anomalous gold and copper mineralization defined by soil sampling at Pinaya has now been tripled from 3 kilometers to over 9 kilometers of strike length and remains open at both ends.

A program to expand the coverage of the soil sampling is currently being designed, and will be implemented over the next few months. A follow-up program of trenching and geological mapping will be also be implemented to define drill targets in the new extension areas.

"Soil and rock geochemistry at Pinaya have been extremely reliable indicators of drilling success in the past," stated Donald Gee, President and CEO. "The high gold and copper values adjacent and continuous to the deposit defined in 2006 demonstrate the important exploration potential of the property. These new extension areas give us an indication that we have the potential to continue to significantly expand the deposit, increase our resources, and add substantial value to the property."

Drilling is ongoing on the Pinaya property. A total of 119 drill holes for more 30,000 meters have now been completed. The primary objective of the 2007 drilling program is to expand and further define the Western Porphyry and Gold Oxide Skarn Zones. A second prospective geological trend followed by the Montana de Cobre, Minas Jorge, and Don Pedro targets is also expected to be drill tested later in the year.

Additional drilling results will be released as they become available.

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