Alturas defines strong copper-gold anomalies at its Chapi Chapi and Sombrero projects, Southern Peru

    BVL: ALT

    TORONTO, Sept. 4 /CNW/ - Alturas Minerals Corp. ("Alturas") (TSX-V: ALT)
is pleased to report that it has identified a copper-gold mineralized trend
greater than 1,300 meters in length and up to 250 meters wide at its Chapi
Chapi project in southern Peru. Best copper-gold intervals from geochemical
sampling of two separate trenches include continuous sections of 18.0 meters
assaying 12.7% copper and 0.13 grams/tonne gold, and 18.0 meters assaying
1.58% copper and 2.84 grams/tonne gold, in an area of historical copper-gold
workings in skarns. In addition, the company is rapidly moving towards drill
target definition at its Sombrero copper-gold project in southern Peru.

    Chapi Chapi Copper-Gold Project

    Miguel Cardozo, President of Alturas commented: "Exploration at Chapi
Chapi has confirmed strong surface copper-gold anomalism hosted by partially
outcropping skarn bodies. In addition we continue to discover additional
copper and gold anomalies hosted within the intrusive rocks and also within
quartzites. We are currently extending soil geochemistry coverage over all
targets and following an induced polarization survey, drill targets will be

geochemical sampling in seven separate trenches within the copper-gold
mineralized corridor:

    These trench geochemical results are from oxidized skarn bodies that cut
limestones within a 1300 x 250 meter mineralized corridor adjacent to an
altered monzonite intrusive body. Surficial supergene enrichment effects
associated with the oxidation and karstic weathering processes may partially
account for some of the very high copper grades present at surface.
    The 6,903 hectare Chapi Chapi project in the department of Apurimac in
southern Peru hosts a large copper-gold-molybdenum skarn system hosted by
Cretaceous limestones and quartzites cut by dioritic to monzonitic stocks. The
limestones are part of the same unit that hosts large skarn deposits in the
Apurimac-Cusco porphyry-skarn belt, such as the Tintaya and Las Bambas
copper-gold skarn projects of XStrata and the quartzite unit hosts an
important oxide copper resource at the nearby Antilla project of Panoro
    The Chapi Chapi property block is immediately adjacent to Alturas's
Utupara copper-gold project and together the two projects comprise a larger
joint venture of Alturas with Minera IRL Limited, a company listed on the
London Stock Exchange ("IRL"). Details of the tenure and terms of the joint
venture agreement can be found in a previous Alturas press release dated
February 28, 2008.

    Sombrero Copper-Gold Project

    As previously outlined in an Alturas press release dated December 13,
2007, outcrop sampling at Sombrero identified strong copper-gold-molybdenum
values from oxidized magnetite skarn bodies with some samples attaining values
in excess of 1% copper and in excess of 1 grams per tonne gold. A detailed
ground magnetic survey has now been completed by Alturas over the 10.0 x 3.5
kilometer zone of alteration hosting the skarns. The survey established that
northeast-southwest elongated magnetic anomalies measuring up to 1,000 x 500
meters in size correspond to individual outcropping copper-gold skarn bodies
and permit the mapping of their extensions out under cover.
    Alturas recently commissioned Fugro Ground Geophysics to carry out an 88
line kilometer induced polarization geophysical survey over the skarn zones,
which is expected to be completed by the middle of September 2008. Detailed
drill targeting will be completed during Q4 of 2008.
    Miguel Cardozo, President of Alturas commented: "At the Sombrero project
strong copper-gold anomalies previously defined in exo- and endoskarn are
currently being followed up using magnetics and induced polarization. We are
working diligently towards outlining drill targets through the integration of
systematic mapping, soil and rock geochemistry, and ground geophysics."
    The 3,800 hectare Sombrero project in the department of Ayacucho in
southern Peru hosts a large copper-gold-molybdenum skarn system hosted by
Cretaceous limestones cut by dioritic to monzonitic stocks. The limestones
form part of the same unit that hosts large skarn deposits in the
Apurimac-Cusco porphyry-skarn belt, of which Sombrero appears to be a western
    The Sombrero project is owned 100% by Alturas, except for some small
claims covering 320 hectares in the central part of the project, which are
owned by a third party. Alturas is negotiating the acquisition of those
