Alturas Ready to Drill Key Targets at Their Utupara Copper-Gold Porphyry Project, Peru

TORONTO, ONTARIO--(CCNMatthews - April 26, 2007) - Alturas Minerals Corp. (TSX VENTURE:ALT) today announced results from new magnetic and Induced Polarization geophysical surveys over the Company's 100% owned Utupara Copper-Gold Project in southern Peru. The surveys confirm strong anomalies that coincide on surface with zones of copper-gold mineralized skarns and breccias. Geophysical modeling indicates that the sources of these anomalies extend to at least 500 metres vertical depth, confirming the volume potential of these copper-gold targets. Alturas is currently making all preparations to drill test the targets in May/June 2007.

Miguel Cardozo, President & CEO, commented "Geophysics has greatly helped in defining important new copper-gold drill targets at Utupara. The combined geological-geochemical-geophysical targets have never been drilled and they exhibit clear indications of strong copper-gold mineralization on surface and in nearby historical drillholes. The potential high-grade nature of these skarn and breccia pipe targets could impact positively on the eventual economics of any mineralized body that Alturas might discover here. These untested geophysical targets are all several hundreds of metres in dimension and appear to extend to depths of at least hundreds of metres. Intensive surface exploration work is currently in progress to locate final drill sites; drilling will commence once road accesses have been cleared of damage by recent heavy rains."

A summary of the four very high priority copper-gold targets defined to date follows:

Cachorro 1 breccia copper-gold target: Alturas is targeting high-grade copper-gold breccia mineralization corresponding to a large chargeability anomaly that has never been drill tested. As recently reported (February 23 2007), detailed trenching in this area defined an extensive zone of copper-gold mineralized breccias measuring 500 x 500 metres in dimension with very strong copper-gold surface values throughout, containing primary chalcopyrite (visible copper) and reporting up to 5,493 ppm (0.55%) copper and 0.57 grams/tonne gold in individual samples.

The new geophysical survey has now defined a large coherent chargeability anomaly (greater than 30 mV/V) with a near-surface footprint 500 x 400 metres in size that remains untested. A local company previously intersected an interval of 108 metres of 0.33% copper and 0.24 grams/tonne gold, including an eight metre interval of 0.66% copper and 0.60 grams/tonne gold, off the southern edge of the chargeability anomaly. This hole confirmed that the strong copper and gold grades associated with the chargeability anomaly on surface extend deep into the subsurface.

Cerro Anasino 1, 2 and 3 skarn copper-gold targets: The Cerro Anasino skarn belt extends for over 2.7 kilometres in strike length and hosts at least three "bulls eye" geophysical anomalies, each hundreds of metres in dimension with corresponding low resistivity, high chargeability and high magnetic susceptibility. The surface projection of these zones closely corresponds with partially oxidized sulfide-rich skarns (gossans) with strong copper-gold surface anomalism in trenches (peak values up to 5.28% copper and 5.07 grams/tonne gold at the Cerro Anasino 3 target). The targets highlighted for drill testing will be bodies of high-grade copper-gold corresponding to the strongly chargeable and magnetic zones defined in the geophysics.

The 4,576 hectare Utupara Project is 100% owned by Alturas and is located 130 kilometres SW of the city of Cusco in southern Peru, in the emerging Eocene-Oligocene mineral belt that also hosts giant copper-gold deposits such as the Tintaya (Xstrata), Las Bambas (Xstrata) and Los Chancas (Southern Copper Corporation). Copper-gold-silver mineralization styles of the porphyry, skarn, breccia, vein and sediment-hosted varieties occur over an area exceeding 4.0 kilometres by 4.0 kilometres in size. Within this zone, a small high-grade gold mine was worked intermittently between 1980 and 1991 by a local company.

About Alturas's QA/QC Procedures.

Strict sample integrity is maintained throughout the geochemical sampling program. The bagged samples are transported by Alturas staff to the city of Cusco in South Peru where they are shipped directly to Inspectorate Services Peru SAC Labs in Lima. Inspectorate is an ISO 9001:2000 certified laboratory that is preparing for ISO 17025 accreditation. At the Inspectorate's Lima facility, all samples are dried then crushed to 90% -10 mesh (less than 2mm) size; then riffle split to obtain an approximately 200 gram subsample. The subsample is further crushed to 95% -200 mesh (less than 75 microns) to obtain a 100 gram split ready for analysis. All samples are routinely assayed for gold by conventional fire-assay methods at Inspectorate's Lima facility, and for 34 additional elements (including silver, copper, lead, zinc) using aqua regia acid digestion followed by Inductively Coupled Plasma-Atomic Emission Spectroscopy ("ICP-AES") analysis.

Alturas follows a rigorous QC/QA program, including routine insertion of standards and blanks as well as assay of duplicate samples at other independent laboratories. Certified standards, of known gold grade are inserted "blind" every 20th sample as an independent check on assay accuracy.
