:: SONARtrac® Flow Monitoring Technology Selected for Cerro Vanguardia Mine, Argentina

CiDRA Minerals Processing announced today that CiDRA was awarded a contract for the installation of three flowmeters at AngloGold Ashanti's Cerro Vanguardia mine in Patagonia, Argentina. CiDRA's SONARtrac systems were chosen by Cerro Vanguardia after a series of performance tests and flowmeter comparisons, and ultimately, the sonar systems were chosen for their reliability and ease of installation. Two of the SONARtrac systems are now installed on the overflow lines from the mill and secondary thickener; while the third meter is awaiting installation on the milling hydrocyclone feed line.

Cerro Vanguardia is a gold and silver mine located northwest of Puerto San Julian in the province of Santa Cruz. AngloGold Ashanti has a 92.5% interest in the mine with the province of Santa Cruz holding the remaining 7.5%. Cerro Vanguardia consists of multiple small open pits with high stripping ratios. The ore bodies comprise a series of hydrothermal vein deposits containing vast quantities of silver, which is produced as a by-product.

CiDRA's SONARtrac systems are non-invasive, which allowed the customer quick installation without any process interruption, and provide the high reliability, performance, and maintenance-free operation the customer required. CiDRA's SONARtrac flow technology is a new class of industrial flowmeter, utilizing measurement principles that are distinct from all other flowmeter technologies operating in the mining industry. As well, SONARtrac systems demonstrate very stable output and superior levels of performance in the presence of highly variable fluid properties.
