Argentex Discovers New Veins at Pinguino Project and Intersects 2 m @ 486.5 g/t Ag and 0.46 g/t Au

Argentex Mining Corporation ("Argentex" or the "Company") (TSX VENTURE:ATX)(OTCQB:AGXMF) is pleased to announce results from 18 holes (1,739 m) of the Phase VIII reverse-circulation ("RC") drill program conducted at its 100%-owned silver-gold and polymetallic Pingüino Project, located in Santa Cruz province, Argentina. These 18 RC holes intersected four new veins on the property: the CSV Vein Group and the Kalia, Pamela and Aurora veins (Figure 1). To date, 63 holes (5,946 m) of the 93-hole (8,410 m) RC drill program, completed in June 2012, have been announced.

 

"The latest assays indicating the discovery of additional precious metal veins at the Pingüino system continue to reinforce our belief that the Project has significantly more potential as we continue to discover high grade precious metal vein systems near surface. Not only are the grades at the CSV veins significant (with 5 of the ten holes reporting greater than 200 g/t Ag eq.) but their east-west orientation is new, opening up the potential for other veins of similar strike," commented Michael Brown, President of Argentex. "The CSV vein group and Kalia join Karina (previously reported in press release dated September 17, 2012) as three potentially significant discoveries made this year in terms of grade of precious metals, strike length and the potential for extensions with further drilling."

RC Drill Program Review ( please visit Argentex's website for graphics discussed below ) :

CSV Vein Group

Ten RC holes were drilled into the CSV veins after a group of parallel structures was discovered with a combination of soil surveys and gradient IP, and subsequently tested with trenches (please refer to the July 24th, 2012 news release where 2 m @ 1,029 g/t Ag and 1.80 g/t Au was reported). The CSV vein structures do not outcrop, as they are obscured mainly by recent sediments.

The CSV group of veins (Figure 2) consists of three main structures (discovered to date):

  1. CSV Norte: strike length of >550 metres and divided into two main sectors: west area dipping to the south (parallel to Karina vein) and merging with Savary vein, and the east area dipping to the north. Best intercept: PR182-12, 2 m @ 564.2 g/t Ag eq. from 19m depth
  2. CSV: group of quartz and oxide veinlets with a minimum strike length of 100 metres and two branches dipping north. Best intercept: PR216-12, 1 m @ 1069.45 g/t Ag eq. from 1m depth
  3. CSV Sur: strike length of about 350 metres and also two branches dipping north. PR246-12, 2 m @ 509.53 g/t Ag eq. from 31m depth

All of the vein structures have an east-west strike and contain anomalous precious metals, particularly in silver, accompanied by elevated values in base metals and indium. Results for each vein are highlighted in Figure 2. These unexposed east-west striking high-grade structures are the first of their type to be found at Pingüino. It is thought that greater potential exists for more discoveries of this new vein type at Pingüino.

Kalia ("KAL") Vein

Four RC holes were drilled into the KAL vein (Figure 3), in follow up to encouraging results from trenching of soil anomalies (please refer to press release dated July 24th, 2012 wherein 1 m @ 175 g/t Ag and 3.06 g/t Au was reported).

KAL is a silver-bearing polymetallic vein, analogous to the Marta Centro (Ag-Au-Zn-Pb-In) vein type. Precious metal mineralisation was intercepted in all holes, ranging from 1 m @ 52.92 g/t Ag eq. to 2 m @ 249 g/t Ag, 0.74 g/t Au, 16.48% Pb, 5.11% Zn and 17.7 g/t indium. KAL is open along strike and at depth, and may hold good potential for precious and base metals.

Pamela ("PAM") and Aurora ("AUR")

The recently discovered PAM and AUR are located at the southern part of the Pingüino project (Figure 1). Both veins are characterised by their considerable strike length (>2 km), their high relief due to the high silica content, and their distribution in multiple parallel branches. The first set of exploratory RC holes on each vein targeted chargeability anomalies outlined by the Phase VIII IP program.

Three RC holes drilled at PAM identified two parallel veins. Holes PR234-12 and PR235-12 encountered anomalous silver and base metals in the west dipping western vein. Two RC holes were drilled at the two different branches of the AUR vein and identified base metal and silver grades in the eastern branch. Hole PR231-12 assayed 49.2 g/t Ag and close to 5% combined Pb+Zn over a 2 metre intersection. The AUR vein is an east dipping structure that can be compared to the nearby polymetallic Tranquilo vein. The PAM and AUR veins warrant further exploration to ascertain their potential for precious and base metals in higher-grade zones along their extensive strike length.

About Pingüino

Argentex's 10,000-hectare advanced silver and gold Pingüino exploration project is located in Argentina's Patagonia region, within the Deseado Massif of Santa Cruz province. The Deseado Massif is an active region of mining with four precious metal mines currently in production, and includes multiple active advanced and early stage exploration projects.

The Company has drill tested 36 of the known 70+ veins at the Pingüino system, which in total have a combined strike length approaching 113 line-kilometres. The Pingüino project is unique within the Deseado Massif region of Santa Cruz province, in that it contains two different and geographically distinct types of mineralisation, one precious metal and the other sulphide-rich polymetallic. The Company also continues to evaluate the geological model of sulphide-enriched potentially mineralized intrusives at depth, forming the probable source for the polymetallic veins exposed on surface.

Pingüino is easily accessible, situated approximately 400 metres above sea level in low-relief topography. An existing system of all-weather roads provides year-round access to the property.

Quality Assurance

Samples selected for analysis are sent to Acme Analytical Laboratories' sample preparation lab in Mendoza, Argentina. From there, sample pulps are sent to its laboratory in Vancouver, Canada for multielement ICP-MS analysis (1DX procedure). Samples overlimit in silver, lead, zinc, and/or copper are reanalysed by a high detection limit ICP-ES analysis (7AR procedure). Samples overlimit in silver from that procedure and gold results >300 ppb are rerun by fire assay (G6 procedure). Acme Analytical Laboratories is an ISO 9000:2001 accredited, full-service commercial laboratory, with its head office located in Vancouver.
