Alturas Reports up to 82.0 metres @ 1.17 grams/tonne Gold and 6.51 grams/tonne Silver from Drilling at Huilacollo Gold Project, Peru

TORONTO, ONTARIO--(CCNMatthews - Jan. 25, 2007) - Alturas Minerals Corp. (TSX VENTURE:ALT) today announced results from the final tranche of fifteen diamond drillholes of the twenty hole, 3,181 metre, Phase 1 drilling program from the Cerro Andamarca and Cerro Huilacollo targets on the Huilacollo Gold Project in southern Peru. This press release supplements results for the first tranche of five drill holes of the program, previously released on November 29, 2006. The best intersection obtained in this final tranche was from hole AM-14, which reported an interval of 1.17 grams/tonne gold and 6.51 grams/tonne silver over 82.0 metres in oxides starting at surface. This interval includes a near-surface higher grade intercept of 1.95 grams/tonne gold and 8.84 grams/tonne silver over 36 metres from 20 to 56 metres. Other highlights included hole AM-16, which reported an interval of 3.52 grams/tonne gold and 49.1 grams/tonne silver over 12 metres from 26 to 38 metres. A single vertical drillhole AM-20, drilled to 436.8 metres vertical depth and designed to test a potential deep porphyry target to the south at Cerro Huilacollo, intersected strong sericite-quartz-pyrite alteration throughout its entire length but did not return significant results.

Miguel Cardozo, President & CEO, commented "We are very encouraged by the strong gold and silver assay results from most of the diamond drill holes at Cerro Andamarca. Latest holes have confirmed the existence of strong mineralization in the third dimension, beneath zones of similar gold and silver tenor reported from surface trenching programs and previous holes. To date we have identified a gold-silver zone exceeding 400 x 200 metres in plan, including high-grade ore shoots associated with steep feeder structures and breccia zones. The mineralization is still open in several directions, and several other untested targets have been identified within the property, including the western concealed part of the Cerro Andamarca combined geochemical/geophysical anomalies plus Andamarca Norte. A Phase 2 drilling program will be required to extend the size of the known gold-silver zone and to explore the new target areas."

All diamond drill holes at Cerro Andamarca are variably inclined holes, drilled on vertical sections spaced on average 50 metres apart and oriented northwest-southeast (parallel to surface trenches of the same orientation previously executed by the Company). Alturas's interpretation of the geology confirms that the zones of best gold and silver grades are controlled by near surface oxidation enrichment, by favorable shallow-dipping volcanic units and by steeply-dipping, silicified and brecciated structures ("feeders"). Average bulk grade intervals quoted here were calculated using a 0.25 gram/tonne gold lower cutoff, and only included zones below this lower grade limit if they were less than four metres in width.

Drillholes AM-18, AM-19 and AM-20 did not report significant results.

The 2,000 hectare Huilacollo Gold Project is located approximately 970 kilometres southeast of Lima and 55 kilometres northeast of the city of Tacna. Alturas holds an option to acquire 100% of the property. Huilacollo is a high sulfidation epithermal gold system outcropping over a strike length exceeding 5 kilometres in length, and Cerro Andamarca is one of three hydrothermal centers recognized to date within this zone.

Bulk mineable, high sulphidation epithermal gold-silver systems of this style are exploited economically throughout Peru in large mines such as Yanacocha, Pierina, Alto Chicama and Aruntani. As reference information only, and in no way intending to imply the ultimate size, grade or economic parameters of gold-silver mineralization that might be discovered at Huilacollo, the dominantly heap leachable oxide ores in deposits such as these generally possess low average grades (0.7 to 2 grams/tonne gold), and very low cutoff gold grades in the range of 0.18 to 0.25 grams/tonne gold.

About Alturas's QA/QC Procedures.

Strict sample integrity is maintained throughout the geochemical sampling program. Core samples (HQ and NQ diameter) from drillholes are logged before sawing longitudinally into two halves, one half is bagged, numbered, and sealed and the other half is stored for further detailed logging and future reference. Individual sample intervals averaged two metres in length. The bagged samples are then transported by Alturas staff to the city of Tacna in South Peru where they are shipped directly to ALS Chemex Laboratories in Lima. ALS Chemex is an ISO 9001:2000-registered laboratory that is preparing for ISO 17025 certification. At ALS Chemex's Lima facility, all samples are dried then crushed to 70% -10 mesh (less than 2mm) size; then riffle split to obtain an approximately 250 gram subsample. The subsample is further crushed to 85% -200 mesh (less than 75 microns) to obtain a 30 gram split ready for analysis. All samples are routinely assayed for gold by conventional fire-assay methods at ALS Chemex'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.
