Gold/Silver Recoveries Further Enhanced at Minera Andes' Huevos Verdes Project
Wednesday August 18, 3:15 pm ET


SPOKANE, Wash., Aug. 18, 2004 (PRIMEZONE) -- Minera Andes Inc. (TSX-V:MAI) (OTC BB:MNEAF.OB - News) -- Metallurgical testing has achieved higher recoveries of gold and silver from underground samples of mineralized material at Minera Andes Inc.'s Huevos Verdes gold/silver vein. The vein under development is part of the San Jose project located in southern Argentina. The recoveries of high-grade gold and silver from the latest round of tests are higher than recoveries reported from a series of tests on drill samples reported by Minera Andes in 2003.

The objectives of the metallurgical program are to lower capital and operating costs, increase metal recoveries, and minimize environmental impact and decrease time to production. In the latest ongoing metallurgical tests in which industry standard extraction methods were used, preliminary results show that recovery of gold from high-grade underground sampling was 96 percent for both flotation and chemical leaching technologies. Silver recoveries ranged from 93 per cent (chemical leaching) to 95.7 percent (flotation). In a previous round of tests on drill samples reported by Minera Andes February 11, 2003 (News Release 03-03), recoveries using the same technologies were 94 percent for gold and 92.1 percent for silver.

Allen V. Ambrose, president of Minera Andes, said, ``As a high-grade gold/silver vein, with potential to be a low cost mine, the latest test results from underground sampling at Huevos Verdes have important implications for production because they may further lower costs and make a more efficient mine.''

Five types of mineralized material were selected for testing from underground workings at Huevos Verdes, where planned underground construction work of tunnels and other infrastructure is being accelerated in order to complete a 3,500-meter work program around the end of 2004. A feasibility study, also planned for completion near the end of the year, is underway for the Huevos Verdes project.

The testing, which is continuing on other sample types, was commissioned by Minera Andes' joint venture partner and project co-owner, Mauricio Hochschild & Cia. Ltda. (MHC) of Lima, Peru (MHC, 51 percent ownership; Minera Andes, 49 percent). C.H. Plenge Laboratory in Lima, Peru tested the high grade samples and will also test other samples as underground construction and sampling continue. SGS Lakefield Research in Canada will conduct check work on duplicates of the metallurgical samples, and crushing and grinding tests.

Huevos Verdes is Minera Andes' most advanced project and is located in the San Jose project, a 98,800-acre mining district-size property with about ten other known gold/silver targets at earlier stages of exploration. Currently, four veins totaling about 32 km of strike length have been identified at San Jose. Only 2.2 km of Huevos Verdes has been drill-tested in detail, or less than half of its presently known 5 km of strike length. The mineralization at Huevos Verdes is open at depth and laterally.

Minera Andes is funded with working capital of approximately US$5.3 million, as at June 30, 2004, for its exploration and underground construction programs. Minera Andes is a mining exploration company focused on gold, silver and copper exploration in Argentina where it holds about 200,000 hectares (500,000 acres) of mineral exploration land and co-owns the advanced stage San Jose/Huevos Verdes gold/silver project now under construction for possible mine production, with a feasibility study underway. Minera Andes has also discovered an enriched copper zone at its Los Azules property, and is acquiring other exploration targets in southern Argentina. The Corporation presently has 70,291,490 issued and outstanding shares.

Forward-Looking Statement -- Although Minera Andes believes many of its properties have promising potential, its properties are in the early stages of exploration. None have yet been shown to contain proven or probable mineral reserves. There can be no assurance that such reserves will be identified on any property, or that, if identified, mineralization may be economically extracted. In addition, Minera Andes' joint venture partner, Mauricio Hochschild & Cia. Ltda., does not accept responsibility for the use of project data or in the adequacy or accuracy of this release.

Construction Accelerates at Minera Andes' Gold/Silver Project
Wednesday August 4, 5:08 pm ET


SPOKANE, Wash., Aug. 4, 2004 (PRIMEZONE) -- Construction work at Minera Andes'(OTC BB:MNEAF.OB - News) (Vancouver:MAI.V - News) Huevos Verdes gold/silver vein, part of the San Jose project in southern Argentina, is expanding and accelerating to complete underground workings by the end of 2004. The expanded and accelerated construction schedule is in part due to the recent underground work at the site that has indicated much higher gold and silver grades from the underground development sampling relative to the grades encountered in drilling from surface (see July 12, 2004 News Release) and to facilitate completion of the announced feasibility study.

Allen V. Ambrose, president of Minera Andes, said, ``We are very pleased to see the work program accelerated. The increased tempo of this program reflects great confidence in the Huevos Verdes discovery. This underground development work, including drifts, inclines, vertical raises and a ramp to increase capacity, are an important step at Huevos Verdes moving us towards the road to production.''

Underground Work Pace Increases

Minera Santa Cruz (MSC), an operating company owned jointly by Minera Andes' and its partner, Mauricio Hochschild & Cia. Ltda. (MHC) of Lima, Peru, plans to complete some 3500 meters of underground workings by the end of the year. Underground work is expected to increase monthly peaking in October. The underground work, estimated to be about one-quarter completed by the end of July, will connect both the North and South access shafts via underground workings when finished. Through their respective ownership interests in MSC, Minera Andes owns 49 percent of Huevos Verdes and the 98,800-acre San Jose project area of which it is a part, and MHC owns 51 percent.

Additional Workers Hired

The quickened pace of the construction schedule at Huevos Verdes has resulted in the hiring of more workers. Since January 2004 when 53 were employed, employment rose to 109 by midyear, and is expected to reach 166 workers by the end of 2004. Occupations represented include engineers, geologists, miners, maintenance personnel, computer systems operators, transportation personnel, and safety personnel. Completing the construction work has required the addition of new equipment, including the addition of several new scoop front end loaders and drills. Currently up to six faces are being worked underground at once and up to 14 faces will be active at any given time through the completion of the underground workings.

Minera Andes is funded with working capital of approximately US$5.0 million to carry out its exploration and development programs. Minera Andes is a mining exploration company focused on gold, silver and copper exploration in Argentina where it holds about 200,000 hectares (500,000 acres) of mineral exploration land and co-owns the advanced stage San Jose/Huevos Verdes gold/silver project now under construction for possible mine production, with a feasibility study underway.
