Toronto, ON, June 8, 2004 – Argentex Mining Corporation (OTCBB: AGXM) today announced that it has completed initial exploration work, including extensive sampling, on two properties located in Santa Cruz Province, Argentina. The primary focus of study was the company's Pinguino property, where Argentex is targeting known mineralization identified by the previous operator of the property. Sampling was also conducted on the El Condor property. The samples are currently being assayed, with results to be released as they become available.

Pinguino

Extensive geophysical and geochemical work has been completed at Pinguino, with a total of 300 rock samples and 1,313 soil samples collected from the property.

Over 75 miles (120 kilometers) of grid line was laid out on a known mineralized strike length of 3.75 miles (six kilometers) over the principal vein, providing a significant tightening of the grid in and around anomalous zones. In total, 1,313 soil samples were collected on this grid at 50-meter intervals on 100 meter spaced lines. Approximately 25 line miles (40 line kilometers) of 3D Induced Polarization (IP) geophysics was completed by SJ Geophysics, an independent Canadian geophysical contractor. Argentex also collected 300 rock samples from a total of 22 earlier trenches. A total of 18 trenches were cleaned out and rock samples were cut using a diamond saw, allowing continuous channel samples to be collected. Rock chip samples were also taken from three of these 18 sites and from four additional trenches.

A system of sample duplicates, including rocks and soils, was completed and the Pinguino samples have been shipped to Acme Labs for assaying.

El Condor

At El Condor, a previously sampled site known to contain visible gold was confirmed and sampled on a rectangular grid of two line miles (3.2 line kilometers), with 46 soil samples collected for analysis. In addition, two line miles of 3D IP data was recorded over the main area of mineralization.

Independent Review

Independent consulting geologist Mr. Bob Morris, P.Geo, visited both the Pinguino and El Condor properties and collected data for an independent geological report that may be required in the future.

“I was impressed with the quality of work being carried out by the Argentex crew at El Condor and Pinguino,” said Morris. “At Pinguino, the soil sample media appears to be consistent across the property and the sample spacing should be adequate to locate near surface targets. Follow-up around anomalous samples may prove to be important in extending known zones. The trenching was reviewed and several of the trenches extended, and re-sampling is of the highest quality and should provide good results. A detailed comparison between the original results and the new samples is important and is expected to both increase the company's confidence in its Pinguino property and verify the prior data.”

Results Forthcoming

Results from Argentex's exploration initiatives at Pinguino and El Condor will be forthcoming following receipt of assay results from Acme Labs. These assays will be compiled and analyzed by Argentex management and independent consultants. This process is scheduled to take place over a two to three month period, with results being released as they become available.
