News Release TSX-V: PDO 06-19 October 5, 2006

FINAL DRILL RESULTS FROM EL REFUGIO-PORVENIR PORPHYRY TARGET

Portal Resources Ltd. (TSX-V: PDO) is pleased to announce that all results have now been received from the program of reverse circulation drilling at the El Refugio-Porvenir porphyry zone on the Arroyo Verde property in Chubut province, Patagonia, Argentina. The 155 square mile property hosts both epithermal gold-silver vein mineralization in a rhyolite dome setting as well as the molybdenum-lead-zinc mineralization in a porphyry setting.

Initially two holes PO-53 and PO-54, drilled to approximately a 300 metre depth on a north-south line 380 meters apart within the heart of the geophysical chargeability anomaly, intersected 260 and 160 meters respectively of rhyolitic ignimbrite overlying a silicious rhyodacitic intrusive. The upper rhyolitic ignimbrite unit is strongly argillic quartz altered with intense kaolinite, zones of silicification, and with limonite and 5 to 15% pyrite in veinlets, disseminated, and in stockworks. In the lower rhyodacite intrusive unit strong prophylic chlorite and green clay alteration and strong silicification predominate with disseminated pyrite and fine grey veinlets with molybdenite, galena and sphalerite.

Hole PO-53 was anomalous in zinc and molybdenite in the lower intrusive unit with zinc ranging from 0.050 to 1.0 % from 170-320 meters and molybdenum from 300-320 meters averaging 0.0150 %. Hole PO-54 was strongly anomalous in zinc and molybdenum in the lower intrusive unit averaging 0.22 % zinc and 0.029 % molybdenite and 340 ppm copper from 214-306 meters (92 meters). The last four meters of the drill hole averaged 0.34 % zinc, 0.27 % lead and 0.045 % molybdenite from 302-306 meters.

Subsequently four additional holes PO-89 to PO-92 were drilled to depths ranging from 136 to 400 meters on 750 to 1500 meter step outs north, east and west from drill hole PO 54. Holes PO-90 and PO-91 drilled 750 meters and 1500 meters north respectively of PO-54 were the best mineralized and intersected galena-sphalerite-pyrite and chalcopyrite as disseminations and veinlets from surface to a depth of 400 meters. Values were strongly anomalous in holes PO-90 and PO-91 averaging respectively: molybdenum 0.0175% from 55 to 313 meters (256 meters) and 0.0196% from 74 to 297 meters (223 meters); lead 0.0363% from 1 to 400 meters (399 meters) and 0.0892% from 19 to 379 meters (360 meters); and zinc 0.0783% from 137 to 400 meters (263 meters) and 0.0892% from 19 to 379 meters (360 meters. Mineralization is associated with an upper quartz-kaolinite (argillic) altered rhyolitic i gnimbrite (0 to164 and 0 to 230 meters in PO-90 and PO-91 respectively), and an underlying quartz-chlorite-magnetite (propylitic) altered rhyodacite intrusive to the end of the holes (163 to 370 meters and 240 to 400 meters in PO-90 and PO-91 respectively). These mineralized zones are modeled as the outer propylitic and argillic alteration shells of a large porphyry system measuring 3 kilometers by four kilometers. Mineralization appears to increase in the northernmost hole PO-91 and is open to the north to the outer rim of the porphyry system, an estimated distance of 1500 meters, as defined by a geophysical Induced Polarization anomaly with strong chargeability. Sulphide and magnetite mineralization as disseminations and veinlets also appears to increase with depth as well as intensity of silicification.

“Although not economic we are encouraged by the large size, intense widespread alteration, and strongly anomalous disseminated molybdenum-lead-zinc mineralization encountered in holes drilled to date as they appear associated with a very large buried porphyry system. We are currently evaluating these results and will look to planning the next phase of exploration soon.” stated David Hottman, Chairman.

Sampling procedure at Arroyo Verde is to prepare two splits from the reverse circulation cuttings at the drill pad, which are sealed and stored at the project site in a secure location. One is retained for reference and the other collected from the site by 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. All work on the project is under the direction of Mr. Gary Nordin, P.Geo. the designated Qualified Person for the project.
