Minera Andes San Jose Project Drilling Hits 4.4 Ounces Per Ton Gold And 364 Ounces Per Ton Silver At The Kospi Vein
|
| | SPOKANE, WA----Sept 14, 2006---- Minera Andes Inc. (TSX-V: MAI and US OTC: MNEAF) is pleased to announce the remaining results of the exploration drill holes at the Kospi silver/gold vein discovered last year at its San José project in southern Argentina. Drill hole SJD-226 encountered 136.72 g/t (4.4 ounces per ton - opt) gold and 11,314 g/t (364 opt) silver over 1.28 meters, the highest gold and silver grades found on the Kospi silver/gold vein to date.
The Kospi vein is located in the area between the Huevos Verdes and Frea Veins, both of which are currently under development (see map). Drilling in 2005 delineated mineralization over a strike length of 250 meters. The follow up 2006 drilling has now identified mineralization over a distance of 1.3 kilometers - a four-fold increase in strike length (see attached map).
Allen Ambrose, president of Minera Andes, said: "The Kospi vein now appears to have sufficient drill spacing to complete an inferred resource estimate. In the fourth quarter of this year we anticipate completing an audit of the drilling to add this resource to the mineral inventory on the San José project where production is planned for early next year."
Two holes, SJD-233 and SJD-234, close to the northwestern limits of drilling at the Kospi vein, encountered 6.46 meters to 0.83 meters of quartz vein and contained no significant gold or silver values. Drill holes SJD-237 and SJD-238 were drilled in the upper central portion of the vein encountering 0.86 g/t gold and 73 g/t silver over 0.49 meters; 11.66 g/t gold and 1,551 g/t silver over 0.52 meters; and 1.77 g/t gold and 213 g/t silver over 1.45 meters (see attached map). The Kospi vein is present in all the holes and the silver/gold mineralization may pick up again along strike. Typically at San José, while the vein itself may well be continuous, the gold and silver mineralization within the vein occurs as pods 300-500 meters in length separated by 100 to 200 meters of unmineralized rock. The drilling indicates the Kospi vein is an open-ended mineralized silver/gold vein that averages about 2.8 meters in width. All of the new results and the previously announced 2005 and 2006 drilling are listed in the tables below.

Assay results for the drilling were reviewed by Brian Gavin, Minera Andes' vice president of exploration, who is an appropriately qualified person as defined by National Instrument 43-101. All samples were collected in accordance with industry standards. Splits from the drill core samples were submitted to Alex Stewart Assayers, Argentina, S.A., in Mendoza, Argentina, for fire assay and ICP analysis. Accuracy of results is tested through the systematic inclusion of standards, blanks and check assays.
