Argentex Intersects 5 m @ 355.2 g/t Ag and 18.66 g/t Au at Pinguino
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 10/11/12 -- Argentex Mining Corporation ("Argentex" or the "Company") (TSX VENTURE: ATX)(OTCQB: AGXMF) is pleased to announce results from the remaining 32 holes (2,751 m) of the Phase VIII reverse-circulation ("RC") drill program conducted at its 100%-owned silver-gold and polymetallic Pinguino Project, located in Santa Cruz province, Argentina. With this release, all holes from the 93-hole (8,410 m) RC drill program, completed in June 2012, have been announced.
Drill Hole Highlights from Final 32 holes:
Savary Vein: Hole: PR224-12: 30 m @ 192.5 g/t Ag and 3.65 g/t Au
Including: 3 m @ 1,156.3 g/t Ag and 3.63 g/t Au
and 5 m @ 355.2 g/t Ag and 18.66 g/t Au
Marta Sur: Hole PR177-12: 19 m @ 272.5 g/t Ag and 0.41 g/t Au
Including: 5 m @ 767.2 g/t Ag and 0.57 g/t Au
Key highlights and successes from the 2011/12 Phase VIII Exploration and Development Program (please refer to news releases from June 25th to September 20th, 2012):
-- Discovery of four new high-grade precious metal veins (CSV group of
veins, Karina, Kalia and Florencia veins) with a combined strike length
estimated at 3 kilometres. High-grade results from these new discoveries
are:
-- Drilled 2 m @ 1,459.5 g/t Ag and 1.17 g/t Au and trenched 1 m @
2,524 g/t Ag and 0.86 g/t Au at Karina Vein
-- Drilled 2 m @ 486.5 g/t Ag and 0.46 g/t Au and trenched 2 m @ 1,029
g/t Ag and 1.80 g/t Au at CSV vein
-- Discovery of high-grade precious metal zones within six previously
discovered vein systems (Savary, Silvia, Marta Noroeste, Marta Oeste,
Tranquilo Sur and Marta Sur)
-- Extension of oxide zones and higher grade sulphide shoot at depth at
Marta Este (2 m @ 281.5 g/t Ag and 5.62 g/t Au)
-- Discovery of high grade zone at Tranquilo in trench (2.5 m @ 4,709.6 g/t
Ag and 0.30 g/t Au)
-- Extended the Pinguino vein system by approximately 50% (from approx. 75
line-km to approx. 113 line-km)
-- Increased the number of veins drilled from 19 to 36 (from the total of
70+ veins discovered to date)
"This final round of drill results has capped another highly successful exploration program at Pinguino. Results reported on the Savary vein are significant as they indicate the potential for high-grade precious metals at the intersection of two vein sets. We believe these structural targets offer the prospect for additional high-grade precious metal intersections at Pinguino," commented Michael Brown, President of Argentex. "This year's exploration program has succeeded in further demonstrating the potential for a significant precious metal deposit at Pinguino. We look forward to incorporating all results into our resource model, anticipated to be released by the end of January 2013, as well as to receiving results from metallurgical studies."
RC Drill Program Highlights (please visit Argentex's website for graphics discussed below):
Savary ("SAV") Vein
SAV vein is a precious metals target with an interpreted strike length of over 3.7 kilometres. Nine shallow RC holes tested anomalous ground magnetics and structurally favourable areas at the intersections of Savary with crosscutting "K system" veins: Kasia, Kimsia, Kimberly, Karina and Karina Norte (Figure 3).
Drill results revealed three high-grade precious metal zones along the vein. We interpret these to be structurally controlled by the intersections of the Savary structure with Kimsia, Karina III/CSV veins, with the section bound by the two branches of the south part of Savary III. These intersections are all open at depth.
The Savary I segment is important for its apparent continuity based on drilling to date and for its potential volume of mineralisation. The Savary II area appears to present a structurally favourable setting for high-grade mineralisation. The high-grade precious metals encountered in PR224-12, with values up to 30 m @ 192 g/t Ag and 3.65 g/t Au, including two high-grade mineralized structures: a silver-rich one with 3 m @ 1,156.3 g/t Ag and 3.63 g/t Au; and a gold-rich one with 5 m @ 355.2 g/t Ag and 18.66 g/t Au, support this assumption. This hole suggests that intersections of the K vein systems, striking ENE, against the NW striking SAV vein system could provide a favourable setting for high-grade mineralisation.

Marta Sur ("MS") Vein
Ten exploratory RC holes targeted previously identified high-grade areas along the two kilometre-long MS vein. Based on detailed ground magnetics, three anomalous areas (South, Central and North) were defined (Figure 2). The North zone, with a different (NNW) strike, had not been previously tested.
Wide intervals of high-grade precious metal values were intersected at the southern anomaly with hole PR177-12 (19 m @ 272.5 g/t Ag and 0.41 g/t Au, including 5 m @ 767.2 g/t Ag and 0.57 g/t Au) and hole PR202-12 (21 m @ 109.9 g/t Ag and 0.26 g/t Au, including 4 m @ 313.3 g/t Ag and 0.63 g/t Au). These holes, together with results from the 2011 Phase VII drill program, indicate a high-grade precious metal system with a strike length of approximately 350 metres.
This is the first high-grade area found at this large and thick quartz vein, and suggests that additional high-grade precious metal values may exist at depth (See longitudinal section, Figure 2).

Silvia ("SIL") Vein
SIL is a very long structure, having a strike length of approximately 4.5 kilometres. It had just two holes drilled in previous exploration phases. The central area (Figure 4) is outlined by both anomalous ground magnetics and gradient IP which was tested with four RC exploration holes.
The drilling reported high-grade precious metal values, along with high-grade base metal values for the two northern holes - 2 m @ 286.5 g/t and Ag 0.88 g/t Au in hole PR180-12 and 4 m @ 131.1 g/t Ag and 0.39 g/t Au in hole PR240-12. These two holes suggest the presence of a new high-grade area at SIL with a potential strike length of 450 metres (Figure 4).

Silver Eq (presented in above tables) is Silver Equivalent of gold plus silver and based upon a price ratio of 50:1 gold to silver. True widths are estimated to be 85 to 90% of the drilled intersection length. See Appendix A below for a full table of assay results.
In our press release dated September 6, 2012, we incorrectly disclosed that the results were from the first 30 holes (3,004 m). This should have been reported as 28 holes (2,717) meters.
About Pinguino
Argentex's 10,000-hectare advanced silver and gold Pinguino 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 Pinguino system, which in total have a combined strike length approaching 113 line-kilometres. The Pinguino 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.
Pinguino 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 greater than 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.
