Orsu Metals Sees Sellable Mineralization At Tallas Project

LONDON (Dow Jones)--Orsu Metals Corporation (OSU.LN) said Wednesday that the results of the metallurgical tests on the Tallas project indicate that a potentially sellable copper-gold- molybdenum concentrate grading 19%Cu, 1.30% Mo and 102g/t Au with respective recoveries of 88%, 89% and 85% can be produced from the Taldybulak sulphide ore material. MAIN FACTS: -Additional optimization work on leaching of the floatation tailings fraction and floatation of oxidized material is planned for the third and fourth quarter of 2010. -Orsu conducted metallurgical testwork at the Stewart Assayers Laboratory (which is independent of Orsu) in Kyrgyzstan. -Two samples, representing the Northern (TH-1; 344.5 kg) and Southern (TH-2; 333.3 kg) mineralized areas of the Tokhtazan deposit were analyzed using the cyanide bottle roll leaching and percolation column tests. -The average grade of -1 was 2.35 g/t Au, whereas the average grade of -2 was 3.17 g/t Au. -Samples were made up of primarily oxidized material collected from drill road cuts at surface. -The Company believes that these results confirm principal amenability of the Tokhtazan ores to heap leaching extraction of gold. -Shares closed Wednesday at 10.5 pence.
