Acero-Martin Drills Long Intersections of High Grade Gold at Pinaya, Southern Peru

Highlights Include 2.00 g/t Gold Equivalent Over 51.15 Meters

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 21, 2007) - Acero-Martin Exploration Inc. (the "Company") (TSX VENTURE:ASD)(FRANKFURT:AMX) is pleased to report that three new drill holes from the Gold Oxide Skarn Zone of its wholly owned Pinaya Project in Southern Peru have all intersected wide intervals of economically significant gold-copper mineralization. These new results include 2.00 g/t gold equivalent over 51.15 meters in PDH-93 and 2.55 g/t gold equivalent over 24.55 meters in PDH-95.

"These exciting results highlight this area's high grade gold potential," said Donald Gee, Acero-Martin's President and CEO. "The Gold Oxide Skarn Zone has proven its potential to become a sizeable near surface gold deposit amenable to low cost open pit heap leach mining. Continued drilling in the area will consist of infill and step-out holes that will aid in the designing and modeling of the zone for near term production."

Currently, there is one drill rig turning at Pinaya with two more planned to arrive shortly. The 2007 drilling program will continue to define the gold resource at the Gold Oxide Skarn Zone area and will also expand the Western Porphyry Zone. Exploratory drilling on the Minas Jorge and Pedro Dos Mil targets will also be conducted.

Minas Jorge and Pedro Dos Mil lie on a separate geologic trend roughly one kilometer east, and adjacent to, the main Pinaya resource area (Western Porphyry and Gold Oxide Skarn Zone). Initial surface and geophysical work have indicated that the targets are part of a multi-kilometer trend that includes Montana de Cobre to the north. The area of mineralization covered by the trend is highly prospective and is potentially larger than the initial resource area to the west. Minas Jorge and Pedro Dos Mil are untested by drilling and are priority exploration targets.

In parallel to the drilling the Company is continuing with the development work associated with fast-tracking the Gold Oxide Skarn Zone into production. Metallurgical, environmental, social-economic, and mine development studies are currently in progress.

Complete drill results are summarized below:

(i) Copper equivalent values (CuEq) and gold equivalent values (AuEq) are
estimated using long-term metal prices, including copper at $1.20 (U.S.)
per pound and gold at $450 (U.S.) per ounce. Adjustment factors to account
for differences in relative metallurgical recoveries for gold and copper
will depend upon the completion of definitive metallurgical testing. CuEq
equals Cu per cent plus Au gram per tonne multiplied by 14.47/(1.20
multiplied by 22.05); AuEq equals Au gram per tonne plus Cu per cent
multiplied by 22.05 multiplied by 1.2/14.47.

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.
