Acero-Martin Appoints Chief Geologist for Pinaya Gold-Copper Project, Peru

VANCOUVER, BRITISH COLUMBIA, Apr 17 (MARKET WIRE) --
Dr. Stewart Jackson, President and CEO of Acero-Martin Exploration Inc.
(the "Company" or "Acero-Martin") (TSX VENTURE: ASD)(FRANKFURT: AMX), is
pleased to announce that the Company has hired Mr. John Romero as Chief
Geologist for its Pinaya project in southern Peru. Mr. Romero is an
accomplished geological engineer with over 15 years experience and a
successful track record of advancing key mineral projects in Peru.

Most recently, Mr. Romero was the Project Manager at Silver Standard
Resources' San Luis project in central Peru where he was responsible for
guiding the exploration program, evaluating and interpreting geologic
data, and coordinating community relations efforts. Under Mr. Romero's
leadership an initial NI 43-101 compliant resource estimate was produced
for the project and the deposit was advanced towards feasibility.

Prior to joining Silver Standard, Mr. Romero was Senior Geologist at the
Toromocho project for Peru Copper Inc. During his four year tenure at
Toromocho, John oversaw more than 130,000 meters of drilling and helped
contribute to the understanding, definition, and expansion of the
deposits at the project. In 2007, the Aluminum Corporation of China
announced a friendly take-over bid to acquire Peru Copper.

Mr. Romero's background also includes positions at a number of other
senior mining companies with operations in Peru, including six years with
Anglo American Exploration Peru S.A. Concurrent with Mr. Romero's
appointment as Chief Geologist, Mr. Cary Pothorin has stepped down as
Vice President of Exploration. The Company wishes to thank Mr. Pothorin
for his contributions to the Company and the advancement of the Pinaya
project.

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 estimate was reported. It
stated 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 category.

As of March 2008, the Company has completed an additional 79 holes
bringing the project totals 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. Acero-Martin
