Acero-Martin Intersects 44.80 Meters of
1.18% Cu at Pinaya
Project, Peru
December 18th, 2007
Vancouver,
BC
Acero-Martin Exploration Inc. (the “Company” or
“Acero-Martin”) is pleased to
announce that new drilling at its wholly owned Pinaya
copper-gold deposit in southeastern Peru
continues to strengthen the resource potential of the project.
Five new step-out drill
holes from the North Western Porphyry Zone (“NWPZ”) area have
all intersected wide intervals of porphyry copper-gold
mineralization. In particular:
- PDH-143, located 100 meters
northeast of previously reported hole PDH-135, intersected 1.08 grams
per tonne gold and 0.24% copper over 23.00 meters.
- PDH-144, drilled 50 meters
southeast of previously reported hole PDH-92, intersected two separate
zones averaging 0.60% copper and 1.11 grams per
tonne gold over 11.30
meters and 0.68% copper over 13.30 meters.
- PDH-145, drilled 100 meters
northeast of previously reported hole PDH-130, intersected 1.18%
copper and 0.22
grams per tonne gold over 44.80 meters.
- PDH-146, drilled 100 meters
northeast of previously reported hole
PDH-116, intersected 0.62% copper over 28.00 meters.
- PDH-147, drilled 50 meters
southeast of previously reported hole PDH-136, returned two separate
zones averaging 0.86
grams per tonne gold over 12.90 meters
and 0.70% copper over 13.90 meters.
To date, thirty-six
drill holes at the North Western Porphyry Zone have defined an area
measuring at least 600
meters in length and up to 400 meters in width,
with mineralization occurring from near surface to as deep as 569 meters.
The North Western
Porphyry Zone is open to the north, east, west, and at depth. The
zone is one of several deposits and targets on the Pinaya
property which have similar geochemical and geophysical signatures.

The intersections
represent apparent thickness, and are 1.25 to 1.5 times the true
thickness. For a location map of the drill holes, please use the

The drilling program at
Pinaya has been successfully concluded for 2007. A total of 53 drill
holes, for 19,600
meters were drilled this year, bringing the project
total to 40,900
meters and 149 holes since drilling commenced in
2004.
With the results
reported above, data for 147 diamond drill holes at the Pinaya project have
been released, only 70 of which were included in the initial resource
estimate reported in September of 2006. The assay results from the
final two holes drilled in 2007 (PDH-148 and 149) are pending and will be
released as soon as the analytical data is received, validated and
compiled.
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 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.

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 approximately 110
km northeast of Arequipa 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.
Non-stop 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.
