Acero-Martin Announces Update on Pinaya Drilling Program

VANCOUVER, BRITISH COLUMBIA, Jul 23 (MARKET WIRE) --
Acero-Martin Exploration Inc. (TSX VENTURE: ASD)(FRANKFURT: AMX)
("Acero-Martin" or the "Company") is pleased to report that it has
completed the previously announced phase one of its 2008 diamond drilling
program on its 100% owned Pinaya Gold-Copper Project in southern Peru.

A total of 5,588 meters (18,333 feet) was drilled in eleven holes to
expand upon the copper-gold deposit outlined by previous drilling and to
test a large undrilled geophysical anomaly to the east of the main
mineralized body. The drill core samples have been submitted to the lab
and the assay results will be reported once all of the results have been
received.

The first eight holes, PDH-150 to 158, were all wide 100 to 200 meter
step out holes drilled at the North Western Porphyry Zone to increase the
projects overall resource base. For hole PDH-159, a deep drilling rig was
brought to the site. The hole was drilled at the North Western Porphyry
Zone to a depth of 800 meters and bottomed in mineralization. It was the
first hole ever drilled to test the depth potential of the deposit beyond
550 meters. The final hole, PDH-160, was drilled at the Los Vientos Zone,
a recently discovered target located 1 kilometer to the southeast of the
main deposit with a strong geophysical signature and trenching highlights
of 2.0 g/t gold over 6.7 meters, including 10.7 g/t gold over 1.2 meters
(trench PTR-152).

The core samples were sent to SGS Laboratories in Lima Peru for analysis.
The analytical results will be reported on receipt thereof and will be
used to guide further exploration in 2008.
