Argentex began a comprehensive exploration program in early 2004, consisting of grid layout, soil sampling, diamond saw channel sampling of trenches, magnetometry and 3D IP geophysics. This work culminated in a 3,000-meter drilling program that tested a number of widely spaced, high priority targets. Work completed to date includes:
|
120 line-kilometers of grid
|
|
Over 3,500 soil samples
|
|
Over 100 line-kilometers of magnetometry
|
|
40 line-kilometers of 3D IP geophysics
|
|
Over 1,600 meters of trenching
|
|
Over 1,400 trench channel and chip samples
|
|
Over 700 drill samples
|
Soil Geochemistry
In 2004-2005, detailed soil sampling on the Marta Vein system returned strong silver, gold and pathfinder element anomalies that correlated well with existing mineralization exposed in trenches. In addition, this work exposed numerous soil anomalies in covered areas. These could potentially lead to the discovery of "blind" veins with precious metal mineralization.

Trenching Highlights
Our initial work program on the Marta vein included diamond saw channel sampling of open trenches left by the previous property owner. Argentex selected a number of these trenches in specific areas of obvious mineralization. Results of the work confirmed the significant silver and gold values in previous grab and chip samples.

Drilling Highlights
2005 areas of drilling
on the Marta vein system
|
Drilling was conducted on four select areas of the main Marta vein system. Some of the best silver results were obtained from the Marta Norte area. The best gold results were found in the Marta Sur area.
The Marta structure remains open in all directions, and numerous other significant veins segments, such as the 3,280-foot (1,000-meter) long Yvonne Vein, remain to be tested by drilling.

3D IP Geophysics
In 2004-2005, approximately 40 line-kilometers of 3D IP geophysics were completed over significant segments of the Marta vein system. Results showed large chargeability anomalies at depths of 100 to 200 meters below surface. The anomalies were situated below the drill testing conducted on the property in 2004-2005 and were scheduled to be the focus of an extensive follow-up program in future years. IP geophysics were conducted by SJ Geophysics, an independent Canadian geophysical contractor.
