Minera Andes Announces First Quarter 2011 San Jose Mine Production


TORONTO, ONTARIO--(Marketwire - April 20, 2011) - Minera Andes Inc. (the "Company" or "Minera Andes") (TSX:MAI)(OTCBB:MNEAF) announces production results from its 49% owned San José mine in Santa Cruz Province, Argentina. Overall production at the San José mine during the first quarter of 2011 was 1,522,207 ounces of silver and 21,412 ounces of gold, of which 49% is attributable to Minera Andes. Production cost information will be provided in conjunction with our first quarter 2011 financial results expected to be released mid-May.

Compared to the first quarter of 2010, first quarter 2011 silver production increased 85% and gold production increased 30%. Mill throughput increased 18% over that period due to higher daily production rates as a result of an increase in the number of high grade stoping areas available for mining, including the high grade Kospi vein. This improved access resulted in a higher average silver head grade mined, consistent with reserve grades, compared to the first quarter 2010. Higher recovery rates also contributed to the increased production.

Compared to the fourth quarter of 2010, first quarter 2011 silver production was 19% lower and gold production was 18% lower. The decrease in silver and gold production was primarily the result of lower mine production with tonnage down by 16% and slightly lower head grades for both silver and gold, partially offset by higher recovery rates. Tonnage in the first quarter of 2011 was lower than the fourth quarter of 2010 primarily as production was impacted by the seasonal effect of fewer production days in the first quarter relative to the fourth quarter of the year.

The difference in the amount of metal sold in the quarter compared to the amount produced was due to timing differences.
