VANCOUVER, BRITISH COLUMBIA--(Marketwired - March 17, 2014) - Argentex Mining Corporation (TSX VENTURE:ATX)(OTCQB:AGXMF) ("Argentex" or the "Company") is pleased to announce the complete trenching results from its 6,000-metre 2013 Phase IX resource development program at its 100% owned Pingüino silver and gold project, located in Santa Cruz Province, Argentina.

Selected results from the trenching program are highlighted in the following table (see Company website for complete results: http://www.argentexmining.com/s/Pinguino.asp)

"The trenching program was undertaken principally to extend the areas of known near-surface mineralisation at Pingüino. In addition to providing better continuation to the high grade zone at Tranquilo, the trenches have extended and confirmed the presence of good medium to high grade gold mineralisation at surface in the more easterly veins at Savary and the CSS-CSV group, which is a very encouraging outcome," commented Michael Brown, President and CEO of Argentex. "As we now have complete results from the trenching, the revised geological interpretation can be completed in preparation for an upgraded mineral resource."

The trenching plays an important role in characterising remnant mineralisation in the oxidized zone at Pingüino. The low silver grade in the trenches is generally not correlated to grade at depth. This is typical for leached material. However, higher grade mineralisation in the trenches is strongly correlated to the presence of supergene enriched, high grade silver zones.

About Pingüino

Argentex's 10,000-hectare advanced silver and gold exploration Pingüino 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 Pingüino system has grown to 70+ individual veins, with a combined strike length approaching ~113 line-kilometers. The Pingüino project is unique within the Deseado Massif region of Santa Cruz province in that it contains two different and spatially distinct types of mineralisation; a precious metal intermediate sulphidation epithermal system and a polymetallic sulphide-rich system.

Pingüino is easily accessible, situated approximately 400 meters 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 multi-element 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.
