PORTAL RESOURCES DRILLS 176 METERS OF 0.031% MOLYBDENUM AT

EL PORVENIR-REFUGIO

Portal Resources Ltd. (TSX-V: PDO) is pleased to announce the assay results from diamond drill hole PO-54 (extension) a test at depth of the molybdenum-copper mineralization intersected in the upper portion of the drill hole.

Reverse circulation hole PO-54 that bottomed in 0.0512 % molybdenum over 11 meters from 295 to 306 meters has been deepened by diamond drilling to a total depth of 765 meters. The drill hole intersected two sections of molybdenum mineralization associated with strong quartz – pyrite – molybdenite stockworks in a strongly sericite altered granitic intrusive as follows: 284 to 460 meters (176 meters) grading 0.031 % molybdenum and 655 to 711.15 meters (54.5 meters) grading 0.0324 % molybdenum. The total interval of molybdenum mineralization in the hole is 230.5 meters.

El Porvenir-Refugio represents a grass roots discovery by the Portal geologic team. The molybdenum mineralization at El Porvenir-Refugio which is increasing in grade in the southern portion of a very large gradient IP anomaly measuring 3 by 7 kilometers remains open to the south with associated anomalous molybdenum and copper soil and rock geochemical anomalies and bedrock outcrops of silicious limonitic and argillic altered Silurian age sandstones.  

Three additional 5 kilometer long pole/dipole IP Resistivity lines totaling 15 kilometers are planned to detail the southern portion of the IP anomaly for follow-up diamond drilling.

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. Mr. Gary Nordin, P.Geo, British Columbia is the designated Qualified Person in accordance with the guidelines of National Instrument 43-101. Mr. Nordin is responsible for the program design and quality control of exploration undertaken by the Company in Argentina.
