ANM Antares Minerals

Antares Minerals Inc. ("Antares") (TSX VENTURE:ANM) is pleased to announce it
has exercised its option to acquire a 100% interest in the Haquira Cu-Mo-Au
project in southern Peru by completing payments totaling US$15 million to Minera
Phelps Dodge del Peru S.A.C. ("MPDP") prior to the March 4, 2010 expiry of the
five year option period (please see Antares press release dated March 17, 2005
for details of the original option agreement). The process of title transfer
will be completed as soon as practical and will most likely be finalized prior
to the end of March, 2010.


John Black, President and CEO of Antares Minerals Inc. commented as follows:

"The acquisition of a 100% interest in the Haquira Cu-Mo-Au Project represents a
milestone achievement for Antares Minerals. We have recently completed an
updated resource estimate for Haquira and the total resource has now surpassed
the critical threshold of 10 billion pounds of contained copper metal, making
Haquira one of the largest undeveloped copper projects controlled 100% by a
junior exploration company. We are now in the process of completing a
Preliminary Economic Assessment (PEA) or scoping study to better elucidate the
potential value of this project. Our goal is to report the results of the PEA in
the second quarter of this year."


About the Haquira Copper Project, Peru

The Haquira project is located in southern Peru and offers excellent potential
for an initial low-strip, low-cost SX-EW copper operation with a subsequent
transition to a higher grade primary porphyry copper-molybdenum
mill/concentrator operation. Antares has recently announced an updated resource
estimate for the Haquira project (see press release of February 26th, 2010). The
estimate encompasses all the known mineralization at the Haquira East and
Haquira West deposits as well as the immediately surrounding areas (Potato Patch
zone), but does not reflect the mineralization recently discovered at the nearby
Cristo de los Andes prospect. It includes both the near-surface secondary
(leachable) copper mineralization as well as the underlying primary
(mill/concentrate) mineralization. This resource estimate utilizes all drilling
completed to date at the Haquira project (through drill hole AHAD-174).
Highlights from this interim resource estimate at a cut-off of 0.3% total Cu for
primary mineralization and 0.2% total Cu for leachable secondary mineralization
are as follows:

Antares has previously announced the results of a Preliminary Economic
Assessment (May 14, 2008) for the near-surface, SX-EW amenable portion of the
Haquira project. This PEA was based upon the an earlier resource estimate
announced in October, 2007 which defined leachable resources at Haquira within
two deposits (Haquira East and Haquira West) with a combined indicated resource
of 133.7 million tonnes at 0.53% total Cu with an additional inferred resource
of 43.6 million tonnes at 0.44% total Cu (0.3% total Cu cut-off, leachable
secondary copper sulphide and oxide mineralization only). This resource is
projected to support a 50,000 t/d SX/EW heap leach operation that will produce
an average of 109 million lbs of copper cathode for 11 years of mine life. The
capital cost to construct the operation is estimated at US$301 million with a
projected IRR of 26.9% and an NPV of US$224 million utilizing a copper price of
US$2.00/lb and a discount rate of 8%. 


The project is located contiguous to, and immediately south of, Xstrata Copper's
Las Bambas Cu-Au project and consists of two blocks of property optioned under
separate agreements as well as additional concessions acquired by Antares for a
total of 20,635 hectares of area. Antares has hereby fulfilled the terms of an
option agreement with Minera Phelps Dodge del Peru S.A.C. ("Phelps Dodge") to
acquire a 100% interest in the original Haquira project by completing optional
payments totalling US$15 million over a five-year period (see Antares press
release dated March 17, 2005). Upon completion of a Feasibility Study, Antares
will be obligated to make an additional payment to Phelps Dodge equal to US$0.01
for each pound of copper in excess of 2.2 billion pounds contained within the
leachable mineral resource. The additional payment will apply to all categories
of leachable resource (inferred, indicated and measured) utilizing a 0.3% total
copper cut-off grade and 50% recovery factor based upon sequential leach
analyses. The additional payment will not apply to primary copper sulphide
resources that are not amenable to leaching.


Antares also has an option agreement with Minera del Suroeste S.A.C. (MISOSA), a
wholly owned subsidiary of Hochschild Mining PLC, whereby Antares can acquire up
to a 60% interest in the Cristo de los Andes project, located contiguous to, and
immediately south of the Haquira project (see Antares press release dated April
28, 2008).

About Antares

Antares is a successful mineral exploration company with highly experienced
technical and management teams. The Company is focused on precious- and
base-metal exploration properties in Latin America that can be quickly and
cost-effectively advanced to the discovery and production stage. In addition to
the Haquira Project in Peru, Antares is also currently exploring the Rio Grande
(Cu-Au porphyry) project in Salta Province of NW Argentina in a 50/50
option/joint-venture basis with Pachamama Resources Ltd., a spin-off from
Mansfield Minerals Inc.


(i) CuEQ = Copper Equivalent is calculated for intervals dominated by primary
mineralization using US$1.50/lb Cu, US$500/oz Au, US$10/oz Ag and US$10.00/lb Mo
and is not adjusted for metallurgical recoveries as these remain uncertain.
Metallurgical recoveries and net smelter returns are assumed to be 100%. The
formula used is as follows: CuEQ = Cu% + (Au g/t x 0.4862) + (Mo% x 10.00/1.50)
+ (Ag g/t x 0.0077). Copper Equivalent contributions are only applied to primary
sulphide mineralization.


All of Antares' exploration programs and pertinent disclosure of a technical or

Mineral resources do not have demonstrated economic viability and future in-fill
drilling and scoping, pre-feasibility and feasibility studies will determine
what percentage of the inferred resource can be placed into the mineable
category. Antares is not aware of any environmental, permitting, legal, title,
taxation, socio-political, marketing or other issue which may materially affect
this estimate of mineral resources.


Certain disclosure in this release, including management's assessment of
Antares' plans and projects, constitutes forward-looking statements that are
subject to numerous risks, uncertainties and other factors relating to Antares'
operation as a mineral exploration company that may cause future results to
differ materially from those expressed or implied. Readers are cautioned not to
place undue reliance on forward-looking statements.
