SPOKANE, WA––March 7, 2008–– Minera Andes Inc. (TSX: MAI and US OTC: MNEAF) is pleased to announce that during the fourth quarter of 2007 drilling has defined 2.8 km of strike length along the Odin and Ayelén veins that have significant potential to further increase the current reserves/resources at its producing San José mine in southern Argentina. The highest grade intercept from this drilling campaign was in hole SJD-412 that encountered 52.44 g/t (1.69 ounces per ton “opt”) gold and 1,147 g/t (37 opt) silver over 1.68 meters (see table below).

During 2007, approximately 28,587 meters of core drilling totaling 113 drill holes was conducted on several targets identified at San José. In September thru December of 2007, 82 holes totaling 20,274 meters were drilled at the Frea, Odin, Ayelén, Frigga, and Lourdes targets. Assay results for 19 drill holes are still pending. Three of the areas (Frea, Odin, and Ayelén) contained high-grade gold/silver mineralization discovered in late 2005 through reconnaissance drilling of blind geophysical targets.

The majority of the fourth quarter 2007 drilling concentrated on the Odin and Ayelén veins covering approximately 2.8 kilometers of strike length along these open-ended mineralized veins. The drilling completed in 2007 extended the known mineralization along the Odin and Ayelén vein trends another 1000 meters along strike – more than a 64% increase in strike length from the 2005 discovery drilling.

Allen Ambrose, president of Minera Andes, said: “The drilling results from the 2007 exploration drilling program continue to expand the San José projects size. This should further facilitate MSC’s plan to double production from 750 to 1500 tonnes per day by the end of this year.”

The San José project is operated by Minera Santa Cruz S.A. (“MSC”) (owned 51% by Hochschild Mining plc (“Hochschild”) (HOC.L: Reuters and HOC.LN: Bloomberg - London Stock Exchange) and 49% by Minera Andes. The discovery of new high-grade silver/gold mineralization in veins such as Odin, Ayelén and Frea represents additional mineralization that can add to the current reserves/resources at the project where production has recently commenced. These discoveries also indicate the large mineral potential of the San José property where more than 40 kilometers of vein trend target is currently known to exist, and of which less than 15% has been explored to date.

Odin Vein
During the 2007 campaign, 30 holes were drilled on the Odin target and the vein is currently defined by a total of 44 holes in an area approximately 1600 meters along the strike of the vein to a depth of approximately 200 meters (see attached map). Highlights of the program included the identification of massive and banded quartz veining with disseminated pyrite and argillic alteration. The Odin vein remains open along strike and to depth.

High-grade gold and silver mineralization was intersected in the fourth quarter 2007 drilling campaign at the Odin vein (see table below). The highest grade intercept drilled in this drilling campaign is described above. Highlights of the Odin vein drilling include values up to 0..46 meters of 34.43 g/t (1.11 opt) gold and 321 g/t (10 opt) silver (SJ-368) which is part of a larger interval running 3.15 meters of 10.57 g/t (0.34 opt) gold and 244 (8 opt) g/t silver. Hole SJD-398 contains 0.50 meters of 6.30 g/t (0.20 opt) gold and 1074 g/t (35 opt) silver at depth of 220 meters below surface. See table below for important intercepts.

Ayelén Vein
Drilling in the fourth quarter has expanded the Ayelén high-grade gold silver vein to a strike length of 1200 meters and a depth of 200 meters (see attached map).  A total of 45 holes have been drilled on the Ayelén vein with 37 holes drilled in the 2007 campaign. The Ayelén vein structure is sub parallel to the Odin vein and dips in the same direction southwest.

Significant intercepts (see table below) at Ayelén include SJD-397 that encountered 28.22 g/t (0.91 opt) gold and 1,759 g/t (57 opt) silver over 1.02 meters. Drill hole SJD-426 encountered 1.53 meters grading 8.21 g/t  (0.26 opt) gold and 1,161 g/t (37 opt) silver within a larger interval of 2.95 meters of 5.41 g/t (0.17 opt) gold and 804 g/t  (26 opt) silver. Hole SJD-428 encountered 1.55 meters containing 15.41 g/t (0.50 opt) gold and 736 g/t (24 opt) silver.

Frea Vein
The Frea vein is located 2 kilometers northeast of the Huevos Verdes vein, and both veins are currently being mined on several levels. Proven reserves of 587,000 tonnes and probable reserves 350,000 tonnes ( totaling 937,000 tonnes grading 7.77 g/t gold and 343 g/t silver – see November 26, 2007 News Release) at the Frea vein are currently delineated over a strike length of about 575 meters and to a depth of approximately 350 meters below the surface. The drilling completed in 2007 extends the known mineralization along the Frea vein trend another 500 meters along strike - an increase of 87% in strike length. Frea Vein mineralization now extends for 700 meters of strike and it remains open to further expansion to the northwest and to depth.

The 2007 drilling concentrated on infill and drilling the northwest extension of the Frea vein. Significant drilling results include SJD-364 that encountered 11.57 g/t (0.37 opt) gold and 1,291 g/t (42 opt) silver over 3.64 meters of high grade mineralization. Drill hole SJD-386 encountered 1.50 meters grading 12.87 g/t (0.41 opt) gold and 710 g/t (23 opt) silver. Hole SJD-391 encountered 1.47 meters containing 9.41 g/t (0.30 opt) gold and 758 g/t (24 opt) silver. In 2007, the drilling at the Frea vein indicates that it is an open-ended mineralized silver/gold vein. Assay results are pending for hole SJD-442.

In addition to the holes listed in the table above, four holes (SJD-370, 372, 377, and 395) were drilled in the Lourdes target plus five holes (SJD-400, 402, 405, 408, and 413) were drilled in the Frigga target and one hole SJD-396 was drilled at the Kospi vein. These holes encountered quartz veining and/or hydrothermal breccia that did not return values above background levels of gold and silver. Although only background gold and silver values were encountered, the geologic features identified at these targets are consistent with precious metal-bearing epithermal systems. One goal of this reconnaissance drilling is to identify promising geologic trends that will be further tested in order to explore for high-grade shoots typical of the mineralization found at the Frea, Kospi, and Huevos Verdes veins. Also, several other targets, such as Aguas Vivas to the north, remain to be drill tested on the property. Assay results are pending on drill holes SJD- 407 and SJD-408.

At Odin drill holes SJD-373, 393, and 399 did not intersect the vein and holes SJD-362, 365, 407, 415, and 424 contained no gold and silver values. Assay results are pending for Odin holes SJD-410, 411, 418, 438, and 440. At Ayelén drill holes SJD-378, 380, and 411 intersected the quartz vein without precious metal values and assay results are pending on SJD-416, 432-439, 441, and 443.

Assay results for the drilling were reviewed by Brian Gavin, Minera Andes’ vice president, 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.
