Acero-Martin Drills 9.80 Meters of 2.28 G/T GOLD
within 27.00 M of 1.22 G/T GOLD, Pinaya Project Peru
April 1st,
2008
Vancouver, BC
Acero-Martin Exploration Inc.
(“Acero-Martin” or the “Company”) is pleased to
report the results from the final two drill holes completed during the 2007
diamond drilling program at the Pinaya gold-copper project in southern
Peru.
Drill holes PDH-147 and 148 were both step-out, resource expansion holes
drilled at the North Western Porphyry Zone target area. The best
hole, PDH-148, intersected 9.80 meters of 2.28 g/t gold within
27.00 m of 1.22 g/t gold. A table summarizing the results is
included below:

Drilling at the North Western Porphyry Zone has been focused on
expanding the deposit with large 100 and 200 meter step-out holes.
Drill hole PDH-148 was a 100 meter step-out to the northeast of PDH-136 and
PDH-149 was drilled 100 meters to the southwest of PDH-132. An
up-to-date drill hole location map has been uploaded to: http://www.aceromartinexp.com/news/
The copper-gold deposit at the North Western Porphyry Zone has now been
defined over a surface area measuring at least 700 meters in length and up
to 400 meters in width, with mineralization running from near surface to as
deep as 569 meters. This is considerably greater than the roughly 400
meter by 150 meter area the zone had been defined over at the time of the
initial 43-101 resource estimate.
The zone remains open for expansion to the northwest, northeast,
southeast, and at depth. It is one of several porphyry and skarn
deposits and exploration targets that have been defined on the Pinaya
project which the Company is continuing to define, explore, and expand.
Drilling recently recommenced at Pinaya for 2008, and a rig is currently
stationed at the North Western Porphyry Zone continuing with the 100 to 200
meter step-out holes (see news release dated March 3rd 2008). Drill
holes PDH-24, 46, and 89 drilled previously in the northwest corner of the
North Western Porphyry Zone intersected an important copper-rich structural
zone with highlights of up to 64.80 meters of 1.03% Cu. Holes
are planned to continue to trace the high grade copper to the
northwest. In addition, holes will continue to expand the North
Western Porphyry Zone to the northeast, southeast, and test the deposit at
depth.
Results from the ongoing 2008 program will be reported as the analytical
data is received, validated and compiled. A table of previous
drilling highlights from the North Western Porphyry target is also included
below:

About Acero-Martin
Exploration Inc.
Acero-Martin’s 100%-owned Pinaya project hosts one of Peru’s
newest and richest copper-gold porphyry/skarn deposits. The project is
located 110 km northeast of Arequipa and approximately 60 kilometers south
of Xstrata’s Tintaya copper-gold mine, and is favoured with excellent
nearby mining infrastructure.
In September of 2006, based on the first 70 holes drilled, an initial
independently calculated NI 43-101 resource estimated that Pinaya hosts an
Indicated Resource of 29.13 million tonnes grading 0.53 g/t gold and 0.42%
copper and an Inferred Resource of 12.72 million tonnes grading 0.41 g/t
gold and 0.41% copper. This equates to approximately 498,000 troy
ounces of gold and 269,000,000 pounds of copper in the Indicated category,
and 168,000 troy ounces of gold and 115,000,000 pounds of copper in the
Inferred.
As of February 2008, the Company has completed an additional 79 holes
bringing the project total to 40,900 meters and 149 holes. Drilling
since the release of the initial resource continues to work to expand the
size of the deposit and test new zones of mineralization. Alongside the
drilling the company is currently completing a preliminary economic
assessment (“scoping study”) to determine the potential for,
and economic parameters of, developing a starter open pit mining
operation. Acero-Martin trades on the TSX-Venture exchange under the
symbol ASD and the Frankfurt stock exchange under the symbol AMX.

Technical
Information
Core of either HQ or NQ size is split in half on site using a diamond
saw, and shipped to SGS Labororatories in Lima, Peru. Samples are crushed
and a portion pulverized for analysis. Trench and drill core samples are
assayed for gold using a 30 gram fire assay procedure with a gravimetric or
Atomic Absorption (AA) finish. A 36-element ICP analysis is then carried
out using an Aqua Regia (4 acid) digestion. Copper assays over 1.0% are
reanalyzed using an AA procedure.
A quality assurance/quality control (QA/QC) program including standard
material of known copper and gold content, blanks, and duplicate samples is
followed. Standards and blanks are inserted every 20 samples. Duplicate
samples are also taken every 20 samples. Approximately 5% of all samples
are sent to an alternate laboratory (ALS Chemex Laboratories in Lima, Peru)
for check assaying of gold and copper. Any inconsistencies are addressed
immediately.
The technical information in this news release has been prepared in
accordance with the Canadian regulatory requirements set out in National
Instrument 43- 101 and reviewed on behalf of the Company by Cary Pothorin,
P.Geo, Acero-Martin’s Vice President of Exploration, a qualified
person.
