Argentex Completes 2013 Resource Development Drilling Program at Pinguino

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Nov 4, 2013) - Argentex Mining Corp. ("Argentex" or the "Company") (TSX VENTURE:ATX)(OTCQB:AGXMF) is pleased to announce the completion of its 2013 resource development drilling program (Phase IX) at its 100% owned Pingüino silver and gold project located in Santa Cruz Province, Argentina. The 3,003-metre drill program, which was undertaken from September 12, 2013 to October 26, 2013, was comprised of 58 holes of reverse circulation drilling targeting oxide material in previously discovered high priority veins, which is not included in the current resource model. Additionally, approximately 7,700 metres of trenching is being finalised to test continuity to surface of mineralisation.

"The program was completed on schedule and on budget. Upon receipt of the new drill results, our plan is to update the mineral resource estimate at Pingüino with a goal of increasing the inventory of near surface oxide material," commented Michael Brown, President and CEO of Argentex. "We continue to review internal engineering studies to determine the next stage of development of the project."

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.
