Minera Andes Reports Third Quarter 2008 Results

Minera Andes Inc. (TSX-MAI and US OTC: MNEAF) today reported a net loss of $3.5 million or $0.02 per share in its third quarter of 2008 financial statements. For the nine months ended September 30, 2008, Minera Andes recorded a net profit of $3.6 million or $0.02 per share. Our financial statements are available at www.sedar.com.

Minera Andes' revenue is derived from Minera Santa Cruz S.A.("MSC"), which is owned 49% by Minera Andes and 51% by Hochschild Mining plc. ("Hochschild") (HOCM.L: Reuters and HOC LN: Bloomberg - London Stock Exchange). MSC operates the San Jose silver/gold mine in southern Argentina, which had its first quarter of positive earning from silver and gold sales in Q2 2008 following the commencement of production at San Jose last year. Hochschild is the operator of the San Jose mine.

As previously reported, silver and gold sales in the third quarter totaled $18.5 million versus $63.2 million for the second quarter. Third quarter 2008 sales of gold and silver are lower than Q2 because an inventory build of metal produced in 4Q 2007 and 1Q 2008 gave the second quarter higher than normal sales. In addition, another build up of metal inventory has occurred in Q3 due to a smelting furnace being temporarily down. The metal in inventory is planned to be sold in Q4 of 2008. The averaged weighted sales prices for Q3 were $861/ounce of gold and $12.37/ounce of silver. The average realized market prices in Q3 2008 were 4.5% lower for Au and 25% lower for Ag than in Q2 2008 (source: KITCO). Since mine start up 15 months ago, San Jose's total sales have been $92.9 million. San Jose's silver and gold sales are un-hedged.

Allen Ambrose, President of Minera Andes said, "Sales and net revenues for the third quarter were less than expected, primarily due to temporary mechanical problems with a smelting furnace causing an inventory buildup of precipitate at site. With the first phase of expansion completed to double the production rate, it is estimated that the San Jose mine will join the ranks of the top ten primary silver producing mines in the world next year when the mine and mill ramp up to the expanded capacity level."

Production

Mill throughput increased 11.5% compared to the previous quarter, but silver production was 9.4% lower and gold production was 0.6% lower than the previous quarter due to lower head grades. San Jose's silver production declined slightly in the third quarter compared to the second quarter. Silver production was 990,000 ounces in the third quarter, compared to 1,093,000 ounces in the second quarter. Annualized, third quarter silver production is running closer to the average grade of the reserves in the original mine plan versus last quarter that was running 33% above the average grade of the reserves. During the life of the mine it is anticipated the gold and silver production will be in line with the mine plan and the reserve grades. Gold production in the third quarter was 12,340 ounces, compared to 12,410 ounces in the second quarter.

For the third quarter, production cash costs on a co-product basis averaged $7.43 per ounce of silver and $431 per ounce of gold. The production cash costs are shown on a co-product basis and are calculated by multiplying the total cash costs by the percentage the calculated value of the silver produced, divided by the number of silver ounces produced in the case of silver, and in the case of gold by multiplying the total cash costs by the percentage of value of gold produced, divided by the number of gold ounces produced. Cash costs include cost of sales, commercial deductions and selling expenses, less depreciation. The production cash costs were calculated using the value of the 12,340 ounces of gold and 990,000 ounces of silver produced in the form of dore, precipitates, and concentrates and the cost to produce those ounces as defined above was $12.7 million. The percentage of the values for the gold and silver production is based on the Q3 2008 average London PM fix for gold and the London fix for silver.

Phase I of the Mine Expansion

Phase I of the expansion has been completed, consisting of an increase in the mining and processing capacity from 750 metric ton per day to 1,500 metric ton per day. Mine production will ramp up to full capacity over the next few months. Currently, approximately 40% of the ore fed to the expanded plant is being processed to produce dore bars and approximately 60% is being processed to produce concentrates. Phase II of the expansion involves connecting to the regional electrical grid which is estimated to be completed in Q1 2009. Meanwhile, there is sufficient diesel generating capacity at the mine to run the mill at its full capacity. Phase III of the mine expansion, which is expected to be completed by mid-2009, involves further expansion of the refining circuit at the processing facility to convert all the concentrate to dore, which will reduce working capital requirements, selling discounts and result in lower production taxes.
