Antares trenching results bode well (February 14, 2005)

Trenching at the Rio Grande project in northwestern Argentina has returned high values of copper, gold and silver.

Antares Minerals (ANM-V) reports that a 106-metre-wide interval averaged 0.57% copper and 0.93 gram gold per tonne. The interval included a 60-metre-wide zone of 0.82% copper, 0.66 gram gold and 3.1 grams silver and an adjacent, lower-grade, 32-metre-long zone of 0.28% copper and 0.36 gram gold. Another zone returned 3.4 grams gold, 10.7 grams silver and 0.2% copper over 14 metres.

Copper mineralization is oxidized and exists both as disseminations and fracture-coating in altered, sub-volcanic, intrusive rocks. The gold-enriched zone trends west-northwest.

Three trenches were intersected perpendicular to the trend of a geochemical anomaly. One, 75 metres to the northwest, exposed a 50-metre-wide zone of copper oxides, while another, 50 metres to the southeast, intersected 70 metres of mineralization. Assays are pending.

A trench in the Discovery zone resulted in 100 metres grading 0.34% copper, 0.43 gram gold and 3.2 grams silver. Included in this interval were 36 metres of 0.54% copper, 0.65 gram gold and 4.1 grams silver.

Drilling of 8-9 holes is under way. Two holes have cut the Discovery zone and a third is testing the Sofia zone.

Rio Grande is one of three Argentine properties in which Antares is earning a half-interest from Mansfield Minerals (MDR-V).
