              - RGA-07-043: 151.00 m with 0.40% Cu, 0.46 g/t Au

             - RGA-07-048: 152.00 m with 0.44% Cu and 0.41 g/t Au

    FOLLOW-UP DRILLING AT DISCOVERY ZONE YIELDS HIGHER GRADE CU-AU INTERCEPTS

             - RGA-07-040: 102.80 m with 0.58% Cu and 0.75 g/t Au
    

    WATERDOWN, ON, Oct. 25 /CNW Telbec/ - Antares Minerals Inc. is pleased to
announce the results from an additional eight holes (4,094 m) of the ongoing
15,000 m drilling program at the Rio Grande copper-gold project in
northwestern Argentina. Highlights of the holes include the discovery of
significant copper-gold mineralization in the previously un-drilled North zone
and the intersection of a higher grade zone in RGA-040 at the northern end of
the Discovery zone. Some of the more significant intercepts are as follows:

    
    - RGA-07-040 (Discovery Zone): 102.80 m with 0.58% Cu, 0.75 g/t Au, and
      13.1 g/t Ag
        - Includes 25.20 m with 1.37% Cu, 1.89 g/t Au, and 18.0 g/t Ag

    - RGA-07-043 (North Zone): 151.00 m with 0.40% Cu, 0.46 g/t Au, and
      12.4 g/t Ag

    - RGA-07-048 (North Zone): 152.00 m with 0.44% Cu and 0.41 g/t Au (Ag
      pending)
        - Includes 60.00 m with 0.54% Cu and 0.53 g/t Au (Ag pending)
        - Within long intercept of lower grade - 428 m with 0.30% Cu and
          0.29 g/t Au

    Thirty holes (14,040 m) have been completed to date and three drill rigs
are currently operating. The first eight drill holes (3,574 m) of the program
were previously announced on September 14, 2007. Assay results are pending for
the remainder of the completed holes and will be reported in subsequent press
releases.

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

    "We continue to be pleased with the results from the current 15,000 m
drilling program at Rio Grande. We are particularly encouraged by the
discovery of extensive copper-gold mineralization in the first few holes into
the North zone. This opens up an entirely new area that warrants considerable
follow-up drilling over the next few months. The higher grade mineralization
encountered in RGA-07-040 is also promising as it demonstrates that the Rio
Grande system is capable of producing zones with higher copper-gold grades.
The current drilling program will be extended through to near year end and we
are currently working with our partners, Mansfield Minerals, to plan an
extensive follow-up program to commence with the new year."
    Five of the eight holes were completed in the Sofia and Discovery zones
and were primarily drilled to test for extensions of mineralization to depth
and to increase the drill-hole density at the northern end of the Discovery
zone. Three of the holes were drilled into the previously un-drilled North
zone. All holes through RGA-07-043 are reported. RGA-07-048 was split and
analyzed prior to holes RGA-07-044 through RGA-07-047 due to the extensive
length of mineralization encountered in the hole and the appearance of
different styles of mineralization in the primary sulphide zone (see
discussion below). Seven of the eight holes reported here intersected
copper-gold mineralization (please see table 1 below and refer to the Antares
website at www.antaresminerals.com for drill-hole location maps and sections).

    Discussion of Results

    The objectives of the current 15,000 m program are (1) to follow-up on
encouraging results from previous drilling campaigns in the Sofia and
Discovery Zones, (2) to drill test the remaining two-thirds of the system that
has not been adequately explored to date, and (3) to provide an initial drill
test of the satellite Northeast Target which bears geological and geochemical
similarities to the nearby Lindero gold deposit owned 100% by Mansfield.
    Copper-gold mineralization at Rio Grande is hosted by a complex sequence
of intermediate sub-volcanic intrusive rocks with variable degrees of
potassic, calcic, and propylitic alteration and local late to post-mineral
intermediate dikes. The mineralization originally consisted primarily as
chalcopyrite and magnetite as disseminations and fracture fillings. The
chalcopyrite has subsequently been partially to completely oxidized to green
and black copper oxides to depths of 300-400 m or more. Oxidation is typically
in situ with little to no remobilization of copper.
    Five of the eight holes reported in this release were completed in the
Sofia and Discovery zones and were primarily drilled to test for extensions of
mineralization to depth and to increase the drill hole density at the northern
end of the Discovery zone. Three of the holes were drilled into the previously
un-drilled North zone. Significant mineralized intervals from the drill holes
are listed in table 1 above. All of the holes were drilled at angles of
50-75 degrees from horizontal to better traverse potentially sub-vertical
zones of mineralization. Reported mineralized intervals represent down-hole
lengths and not true thicknesses as there is currently insufficient geological
data to calculate true thicknesses (please see table 1 below and refer to the
Antares website at www.antaresminerals.com for drill-hole location maps and
sections).
    Drill holes RGA-07-036 (-70 degrees) and RGA-039 (-60 degrees) were
drilled to complete a drill fence within the central portion of the Discovery
zone. The holes each intersected lengthy intervals of low to moderate grade
copper-gold mineralization.
    Drill hole RGA-07-038 (-70 degrees) was completed as a test for
mineralization at depth beneath the Sofia zone. The hole encountered a narrow
zone of higher grade copper-gold mineralization suggesting that the system may
become thinner and higher grade with depth in this area (7 m with 0.76% Cu and
0.99 g/t Au).
    Drill holes RGA-07-40 (-75 degrees) and RGA-07-41(-60 degrees) were
drilled to complete drill sections at the northern end of the Discovery zone
in the vicinity of several previous drill holes and trenches with better
grades. RGA-07-040 intersected 102.80 m with 0.58% Cu, 0.75 g/y Au, and
13.1 g/t Ag which includes a zone of 25.20 m grading 1.37% Cu, 1.89 g/t Au,
and 18.0 g/t Ag. This high grade zone is likely a feeder to the more extensive
areas of lower grade. RGA-07-041 encountered a 26.00 m interval with 0.47% Cu
and 0.73 g/t Au within an envelope of lower grade material. Previous trench
and drill core results from the vicinity of RGA-07-040 include the following
intercepts: RGA-05-12: 86 m with 0.45% Cu and 0.66 g/t Au, Trench-1: 97 m with
0.57% Cu and 0.97 g/t Au, and Trench-2: 30 m with 0.74% Cu and 1.19 g/t Au.
This zone is emerging as a center of higher grades and warrants extensive
follow-up drilling.
    Drill holes RGA-07-042 (-50 degrees), RGA-07-043 (-50 degrees) and
RGA-07-048 (-60 degrees) were all drilled to the south to test the copper and
gold soil anomaly that defines the North zone of Rio Grande. Two of the tree
holes encountered significant intervals of copper-gold-silver mineralization
(RGA-07-043: 151 m with 0.40% Cu, 0.46 g/t Au, and 12.4 g/t Ag from surface
and RGA-07-048: 152 m with 0.44% Cu and 0.41 g/t Au which includes a zone of
60 m with 0.54% Cu and 0.53 g/t Au). The mineralization in RGA-07-048 is
within a very extensive zone of lower average grade (428 m with 0.30% Cu and
0.29 g/t Au). The geometry of this mineralization is not well constrained and
additional drilling will be required to determine true thicknesses. The lower
portion of this mineralization is characterized by primary sulphide
mineralization consisting of chalcopyrite and pyrite associated with extensive
and locally pervasive replacement of the intermediate intrusive host rock by
diopside and coarse secondary biotite. Grades locally exceed 1% Cu and
1 g/t Au. This is the best expression of this style of mineralization
encountered to date at Rio Grande and hole RGA-07-048 was split and analyzed
prior to other pending holes to more rapidly provide information to guide
additional drilling in the area.

    About the Rio Grande Project, Salta Province, Argentina

    The Rio Grande project is very favorably located along the prominent
northwest-trending Archibarca Lineament which also controls the location of
the world-class giant Escondida porphyry copper deposit 150 km to the
northwest in Chile. The Rio Grande project shares many geologic similarities
with the Bajo de Alumbrera porphyry copper-gold deposit which is located along
a similar northwest-trending regional structural lineament approximately
300 km to the south.
    Copper-gold mineralization at Rio Grande occurs within a distinct two-km
diameter ring fracture zone defined by IP chargeability as well as copper and
gold soil geochemical anomalies. Exploration to date has focused on the better
exposed Discovery and Sofia zones along the south-eastern portion of the
system. Drilling and trenching in these areas has defined a copper-gold
mineralized zone 1500 m long, 80-200 m wide, with a minimum depth of 200 m.
Mineralization remains open in both directions along strike and to depth. An
extensive trenching program completed by Antares earlier this year was
successful in identifying additional drill targets on the property.
    Antares is earning a 50% interest in the Rio Grande project pursuant to
an agreement with Mansfield Minerals Inc. ("Mansfield", MDR.TSX-V). Antares
has recently completed the required expenditures and payments and plans to
vest in its 50% interest in the property shortly. Antares and Mansfield will
formalize a definitive joint venture agreement in the near future to fund
ongoing development at Rio Grande on a 50/50 basis with Antares as the
operator.

    About Antares
    -------------

    Antares is focused on the acquisition and exploration of 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 Rio Grande copper-gold project in Argentina, Antares is aggressively
advancing the Haquira SX-EW copper project in south-central Peru, immediately
adjacent to the Las Bambas copper project of Xstrata Copper. Antares recently
announced an updated resource estimate for the near-surface, SX-EW amenable
portion of the Haquira project (October 09, 2007) and is process of completing
the corresponding 43-101 technical report which will also include a
preliminary economic analysis. Based on 215 drill holes completed through the
end of 2006, Haquira hosts an 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). The current resource estimate does not incorporate
any of the 2007 drilling that has been focussed on delineation of the newly
discovered primary copper-molybdenum-gold zone beneath the Haquira East copper
oxide zone. Antares has an option to acquire a 100% interest in the Haquira
project from Minera Phelps Dodge del Peru S.A.C.
