Antares intersects 189 m with 0.70% cu and 0.67 g/t au at Sofia North zone of Rio Grande copper-gold project, Argentina



    WATERDOWN, ON, Sept. 14 /CNW Telbec/ - Antares Minerals Inc. ("Antares",
ANM.TSX-V) is pleased to announce the results from the initial eight holes
(3,574 m) completed of the ongoing 15,000 m drilling program at the Rio Grande
copper-gold project in northwestern Argentina. A total of 21 holes (9,607 m)
has been completed to date and three drill rigs are currently drilling. Assay
results are pending for the remainder of the completed holes and will be
reported in subsequent press releases.
    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 along strike. Seven of the eight holes intersected
copper-gold mineralization but the highlight of the program has been
drill-hole RGA-07-34 at the northern end of the Sofia zone (please see table 1
below and refer to the Antares website at www.antaresminerals.com for
drill-hole location maps and sections).
    Drill-hole RGA-07-34 intersected a 189 m interval with 0.70% Cu and
0.67 g/t Au commencing at a depth of 140 m. This is the best intersection to
date at the Rio Grande project. The hole is located immediately to the
northwest of the two previous best holes: RGA-06-26, 150 m to the south (158 m
with 0.46% Cu and 0.51 g/t Au) and RGA-06-24, 180 m to the southeast (128 m
with 0.47% Cu and 0.71 g/t Au). RGA-07-30 was drilled to the west of RGA-06-26
to test for down dip extension of mineralization and encountered narrower
zones of mineralization with higher grades (17 m with 0.69% Cu and 0.94 g/t
Au). The mineralization in RGA-07-34 was encountered at a shallower depth than
anticipated and remains open to the west and north.

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

    "We are very pleased with the results from the first few holes of the
current drilling campaign at Rio Grande. The drilling continues to define a
large zone of copper-gold mineralization at the now continuous Discovery-Sofia
zones. More importantly, the strong and relatively near-surface intercept in
RGA-07-34 has extended the zone of higher grade copper-gold mineralization at
the northern end of Sofia zone an additional 150 m to the north. This is the
best drill intercept to date at Rio Grande and there is room to extend the
mineralization to the west and north towards the North zone target area.
Drilling is currently focused on completing holes into the previously untested
North zone. We look forward to providing additional results in the near
future."

    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.
    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 along strike. They complete a series of ten drill
sections located at approximately 150 intervals along the 1500 m strike length
of the combined zones. Each section contains two to three drill holes. These
drill holes confirm that mineralization at the Sofia-Discovery zone occurs as
an accurate zone that dips steeply to the west and northwest (approx
70 degrees) towards the center of the Rio Grande system with a true width of
approximately 80-150 m. Reported mineralized intervals represent down-hole
lengths and not true thicknesses. However, all holes are drilled to the east
or south at angles of minus 60-80 degrees to intersect the mineralized zones
at relatively high angles.
    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 up to 300-400 m. Oxidation is typically
in situ with little to no remobilization of copper.
    Drill-hole RGA-07-34 was completed on the northernmost drill fence at the
Sofia North zone and intersected a 189 m interval with 0.70% Cu and
0.67 g/t Au commencing at a depth of 140 m. This is the best intersection to
date at the Rio Grande project. The hole is located immediately to the
northwest of the two previous best holes: RGA-06-26, 150 m to the south (158 m
with 0.46% Cu and 0.51 g/t Au) and RGA-06-24, 180 m to the southeast (128 m
with 0.47% Cu and 0.71 g/t Au). RGA-07-30 was drilled to the west of RGA-06-26
to test for down dip extension of mineralization and encountered narrower
zones of sulphide mineralization with higher grades (17 m with 0.69% Cu and
0.94 g/t Au). The mineralization in RGA-07-34 was encountered at a shallower
depth than anticipated and remains open to the west and north.
    Drill holes RGA-07-29 and RGA-07-31 were drilled to fill the untested
area between the Sofia and Discovery zones. These holes intersected narrower
zones of low-grade copper-gold mineralization and demonstrate that the Sofia
and Discovery zones are connected.
    Drill-hole RGA-07-32 was collared to test for the down dip extension of
mineralization in the Discovery zone. The hole intersected numerous 5-30 metre
intervals of moderate-grade copper-gold mineralization over a length of
several hundred metres. Down-hole surveys indicate the hole is strongly
deviated and may not have completed tested the target area. This hole will be
re-drilled and efforts are underway to minimize hole deviation in the future.
    RGA-07-33, GRA-07-35, and RGA-07-37 were all drilled to test for a
southwestward extension of the discovery zone. They encountered several narrow
zones of copper-gold mineralization but generally indicate that the Discovery
zone is terminating to the southwest.

    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. The Haquira
project hosts an inferred mineral resource, at a 0.3% total copper cut-off
grade, of 156.3 million tonnes grading 0.49% copper amenable to SX-EW
processing (leachable copper oxides and secondary sulphides only). See Antares
press release dated February 14, 2006. An additional 97 drill holes were
completed in late 2006 and an updated resource estimate will be completed in
the third quarter of 2007. Antares has also recently announced the discovery
of high-grade primary porphyry copper-molybdenum-gold mineralization beneath
the secondary copper blanket at the Haquira East zone (see press releases of
12 July and 9 August, 2007) Antares has an option to acquire a 100% interest
in the Haquira project from Minera Phelps Dodge del Peru S.A.C.
