The portion of the mineralized system assessed in the PEA is limited to the indicated and inferred silver-gold oxide resource previously identified by Moose Mountain Technical Services in its National Instrument (NI) 43-101-compliant August 2009 report.

The company had been focused on drilling the polymetallic sulphide mineralization at Pinguino through until late 2009, at which time Argentex began to focus on the property’s near-surface silver-gold oxide horizon.

Argentex intends to use data from silver-gold discoveries made in 2010, as well as results from the current 2011 drill program in progress, to update both the PEA and the 2009 Technical Report later this year.

Additional veins that have been tested since preparation of the 2009 technical report contain significant intersections of high-grade silver and remain open along strike and to depth.

The PEA covers nine of the 51 mineralized veins identified to date at Pinguino.

Additional veins that have been tested since preparation of the 2009 technical report contain significant intersections of high-grade silver and remain open along strike and to depth.
