Drilling Expands Gold Oxide Skarn Zone at Acero-Martin's Pinaya Deposit, Southeastern Peru

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 7, 2007) - Acero-Martin Exploration Inc. (the "Company") (TSX VENTURE:ASD)(FRANKFURT:AMX) is pleased to report that four new drill holes from the Gold Oxide Skarn Zone of its wholly owned Pinaya project in southeastern Peru have all intersected wide intervals of economically significant gold-copper mineralization. These new results include 2.61 g/t gold and 0.11 % copper over 7.5 meters within a larger intercept of 1.10 g/t Au and 0.08 % Cu over 56.50 meters in PDH-103.

The Gold Oxide Skarn Zone ("GOSZ") is an extensively mineralized body that continues over 500 meters of strike length, and has been tested to a depth of approximately 200 meters. The zone hosts a near-surface, high-grade gold deposit that has the potential to be developed using open-pit mining methods. Ongoing drilling at the zone is focused on expanding and defining its limits.

Complete drill results are summarized below:

Donald Gee, President and CEO of Acero-Martin, said: "The results to date continue to meet or exceed our expectations. Some of our short term objectives are to prove an overall increase in the size of the resource and to fast track our asset into production. The latest results strengthen our beliefs regarding the size of the resource and the economic viability for production."

Drill holes PDH-101 and PDH-102 were step-out holes roughly 75 and 125 meters respectively along strike and to the southeast of PDH-06. Both holes were drilled at an orientation of -50 degrees and 225 degrees azimuth. The anomalous gold and copper values encountered here confirm the continuity of the mineralization along strike. Sporadic high values of 7.4, 4.4, and 2.0 g/t gold were intersected in PDH-101, and values of 3.99 and 6.83 g/t gold were intersected in PDH-102. All of these high gold values occurred over 1.5 meter sample widths.

Drill holes PDH-103 and PDH-104 were both designed to intersect two distinct targets. The upper parts of the holes were drilled to intersect gold bearing skarn alteration, and the lower parts to intersect copper-gold bearing diorite porphyry.

PDH-103 was an infill hole between PDH-04 and PDH-93/PDH-94. It was drilled at an orientation of -60 degrees and 225 degrees azimuth. The upper part of the hole intersected gold bearing skarn alteration, and the lower part of the hole intersected copper and gold bearing diorite porphyry intrusive and mineralized wall rock material.

PDH-104 was a strike extension hole 50 meters to the northwest of hole PDH-04, and had a similar orientation to PDH-103. It also intersected gold bearing skarn mineralization, diorite porphyry intrusive, and mineralized wall rock material at depth.

An up-to-date drill hole location map has been uploaded to the Company's website.

The Pinaya property is located near the south-eastern end of the Andahuaylas-Yauri metallogenic belt of southern Peru, 110 kilometers northeast of Arequipa, and just seven kilometers off of the haul road to Xstrata's Tintaya mine. The Pinaya deposit can be characterized as a porphyry copper-gold, skarn, and supergene gold-copper deposit. These types of deposits are widespread throughout the Andahuaylas-Yauri belt and continue from southern Peru to northern Chile. Similar deposits in the region include Tintaya which is host to a resource of about 139 Mt with 1.39 % Cu and 0.23 g/t Au, Antapaccay with 383 Mt averaging 0.89 % Cu and 0.16 g/t Au; Quechua with 300 Mt averaging 0.68 % Cu; and Coroccohuayco with 155 Mt averaging 1.57 % Cu and 0.16 g/t Au.

Currently, there are two drill rigs turning at Pinaya. The first rig is continuing to expand and define the GOSZ and the second is drilling widely spaced step-out holes at the Western Porphyry Zone. A third rig is scheduled to arrive this month. Alongside the drilling development work for an initial gold operation is continuing.

Additional assay 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 persons 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. Reported drilling intersections represent apparent thicknesses, and are 1.25 to 1.5 time the true thickness.
