TORONTO, ONTARIO--(Marketwire - Sept. 4, 2012) - Portex Minerals Inc. ("Portex" or the "Company") (CNSX:PAX) is pleased to announce the latest drilling and geophysical survey results for the Lagoa Salgada deposit in South Western Portugal. Portex is a mineral exploration and development company with properties in Spain and Portugal. Portex has previously announced that it has entered into a non-binding Memorandum of Understanding to acquire the outstanding securities of Scandinavian Metals Inc. with exploration properties in Sweden and an indirect investment in properties in Norway.
The drilling was conducted to follow up on initial drilling results from the 2011 exploration program (see Portex news release dated September 26, 2011). The latest program also incorporated the analysis of results from the Technical Report and resource estimate completed by Tetra Tech, as reported in a Portex news release dated January 4, 2012.
The first two holes of the planned 7-hole Phase 2 program were completed. Percussion pre-collaring of overlying barren sediments was completed in the first half of March 2012. Diamond drilling commenced on June 25 and was completed on July 27, 2012. As in the previous drill programs, samples were collected and shipped to an accredited assay laboratory owned by ALS Laboratories at its Seville Spain facility. Assay results were recently received, compiled and composited for disclosure, as shown in the table below.

Drillhole PX02 was targeted to evaluate the eastern downdip extension of the SE massive sulphide lens delineated by 2011 drilling as presented in the Technical Report. The hole encountered a residual gossan horizon at the contact between the overlying Tertiary sediments and the older Paleozoic volcanic sequence hosting the Lagoa Salgada deposit. Below the gossan, the hole encountered altered volcanic tuffs and sulphide stockwork mineralization and a narrow massive sulphide intercept between 169m and 179m depth. No significant assays were obtained from hole PX02.
Hole PX05 was located to further evaluate the tenor and continuity of the SE lens and was collared between previous holes PX04A and PX08, which were 111m apart. Hole PX05 intersected a thick gossan at the unconformity followed by 55m of massive and semi-massive sulphides. The hole confirmed the continuity of the SE lens and also the relatively higher grade upper section of the sulphide sequence which, as in PX03 and PX08, contains significant grades of gold, silver, lead and zinc. The upper sulphide zone contained a continuous section 18.10m in thickness grading 1.30 g/t Au, 72.03g/t Ag, 5.54% Pb and 7.33% Zn. The gossan zone above the sulphides also contains appreciable gold, silver and lead. Immediately below the gossan an interval of enriched copper and silver exists, likely from supergene enrichment, which graded 112 g/t silver and 4.35% copper. Hole PX05 terminated in a clay-rich fault from 221-223.8m which prevented further drilling. The typical volcanic tuff-stockwork assemblage below the massive sulphide was not intersected which suggests that the hole ended prematurely. Portex is examining its options with respect to extending PX05 at depth.
Portex contracted downhole transient EM surveys on both holes immediately following the drilling. IGT Geophysical Technology, SL, a Spanish firm with previous experience in the Pyrite Belt, conducted the surveys. Hole PX02 detected the adjacent sulphide mass to the west (intersected in PX08 (2011)) and hole PX05 demonstrated two conductive responses: one strong anomaly for the sulphide zone intersected by the hole and a second weaker off-hole response interpreted to reflect the main sulphide body at Lagoa Salgada to the west. The conductive zones were interpreted to dip 78-75°NE. The interpreted dip is steeper than expected and may indicate that hole PX02 was terminated above the target sulphide horizon. Consideration will be given to extending this hole to depth if re-entry is possible. Portex expects that completion of the remaining five holes of the planned Phase 2 program will greatly assist in refining the geologic model and potential for resource expansion at Lagoa Salgada.
Portex has incorporated a quality assurance and control program for the Lagoa Salgada drilling samples which inserts laboratory standards and blanks into the assayed sample shipments to ensure reliability and accuracy of core analytical data. Assaying is being conducted by ALS Laboratories at its Seville Spain facility. All drill core is maintained in a secure facility on the concession under the supervision of Portex personnel.
Portex is a Toronto-based mineral development company, focused on acquisition and development of base and precious metal properties in Europe. The Company has properties in Spain and Portugal.
The Lagoa Salgada concession in Southern Portugal hosts the Lagoa Salgada deposit, a polymetallic volcanogenic massive sulphide ("VMS") deposit which consists primarily of lead and zinc, along with some gold, silver and copper. Portex completed a NI 43-101 Technical Report and Resource Estimate (Wardrop, a Tetra Tech company ("Tetra Tech"), January 9, 2012) which showed an indicated resource, at a 3.5% Zinc-Equivalent ("Zn-Eq") cut-off, of 2.9 million tonnes at 7.2% zinc equivalent and an inferred resource of 1.6 million tonnes at 5.5% zinc equivalent, as announced previously in Portex's news release dated January 4, 2012. The NI 43-101 Technical Report and Resource Estimate was filed on SEDAR on January 11, 2012.
The Toral Project covers a license area of 2,400 ha located in the province of Leon in North West Spain, approximately 400 km northwest of Madrid. The property is accessed by infrastructure including a regional highway, a high voltage power line and a railway line which links to the Asturianas zinc-lead smelter via the city of Leon. The April 30, 2012 NI 43-101 technical report (updating the April 2011 Technical Report commissioned by GoldQuest), commissioned by Portex and prepared by Micon International Co Limited, estimated an indicated resource for the Toral project of 4.04Mt grading 5.3% lead, 6.5% zinc, 0.11% copper and 41g/t of silver. In addition, Micon estimated an inferred resource of 4.67Mt grading 4.44% lead, 5.4% zinc, 0.14% copper and 32g/t of silver. A cut-off grade of 7% combined lead and zinc was used to define the Toral project's mineral resources. The complete NI 43-101 technical report may be found on the Company's profile at www.sedar.com.
