PORTAL INTERSECTS 400 METERS OF 1-5 % DISSEMINATED GALENA-SPHALERITE-PYRITE-CHALCOPYRITE SULPHIDES AT EL REFUGIO PORPHYRY TARGET

Portal Resources Ltd. (TSX-V: PDO) is pleased to announce that it has completed a program of reverse circulation drilling at the El Refugio Porphyry anomaly 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 molybdenum-lead-zinc-copper mineralization in a porphyry setting.

Four reverse circulation drill holes averaging 400 meters in depth were drilled on 750 to 1500 meter step outs north, east and west from hole PO 54 which averaged 0.22 % zinc, 0.029 % molybdenite, and 340 ppm copper from 214-306 meters (92 meters) in a siliceous propylitic altered rhyodacite intrusive unit.

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 with a sulphide content ranging from 1-5 %. Mineralization is associated with an upper quartz-kaolinite (argillic) altered rhyolite ignimbrite (0-164 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 as defined by a geophysical Induced Polarization anomaly with strong chargeability, an estimated distance of 1500 meters. Sulphide and magnetite mineralization as disseminations and veinlets also appears to increase with depth as well as intensity of silicification.

Portal Resources is encouraged by the extensive zones of alteration and disseminated lead-zinc-copper mineralization encountered in holes PO-90 and PO-91 from surface to a depth of 400 meters as they appear associated with a very large porphyry system with a significant outer base metal component. All samples have been submitted for assay and results are expected in 2-3 weeks.

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.
