Toronto, September 4, 2008 – 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.

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 defined.”

The accompanying table highlights key results from Alturas’s 2008 trench geochemical sampling in seven separate trenches within the copper-gold mineralized corridor:

"Chapi Chapi Corridor" 2008 trench sampling

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 Minerals.

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.

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 extension.

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 claims.
