Portal Mobilizes Drill for Deep Test of the El Porvenir-Refugio Molybdenum-Copper Porphyry Target

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Nov. 6, 2006) - Portal Resources Ltd. (TSX VENTURE:PDO) is pleased to announce the mobilization of a diamond drill on the El Porvenir-Refugio target at the Arroyo Verde project to deepen reverse circulation drill hole PO-54 from a depth of 306 meters to a depth of 700-800 meters.

Portal's recent drilling of six 300-400 meter deep reverse circulation drill holes over an area of 4 square kilometers within a strong Induced Polarization anomaly measuring 3 by 4 kilometers in size with coincident porphyry style alteration outlined a broad outer zone of strongly anomalous lead-zinc mineralization, with a central zone of molybdenum-copper mineralization at a depth of 20 to 300 meters below surface in holes PO-53 and PO 54 which remains open to depth. (See previous news release October 06, 2006).

Hole PO-54 was especially anomalous in molybdenum and copper averaging 290 ppm molybdenum and 340 ppm copper from 214-306 meters (92 meters) with the bottom 11 meters grading 0.0512 % molybdenum with three values greater than 0.11% molybdenum.

Mineralization in hole PO-54 is associated with a highly altered intrusive with disseminated molybdenite, pyrite, and magnetite. Emplacement of the intrusive which is coincident with the large IP chargeability anomaly measuring 3 kilometers by 4 kilometers, is thought to be controlled by regional northwest and northeast faults with associated linear fluorite, barite, and manganese mines.

This mineralization and geological setting at El Porvenir-Refugio is similar to several large molybdenum porphyry deposits in British Columbia such as the Glacier Gulch deposit of Blue Pearl where mineralization is located at a depth of 300-400 meters below surface.

Sampling procedure at Arroyo Verde is to split the core on site with one half delivered to Alex Stewart Argentina S.A., a subsidiary of the international laboratory Alex Stewart (Assayers) Limited and transported to their laboratory in Mendoza for analysis. Samples are analyzed by fire assay for gold and silver and ICP for trace elements. Work on the Arroyo Verde project is under the direct supervision of senior geological personnel in Argentina, however overall direction is the responsibility of Mr. Gary Nordin, P.Geo. British Columbia, the designated Qualified Person in accordance with the guidelines of National Instrument 43-101.
