CiDRA Minerals Processing ( was awarded, through M3 Engineering & Technology (, an added contract to supply SONARtrac process monitoring systems to the Peñasquito project in Mexico, expanding its installed base of CiDRA’s SONARtrac systems to 17. This project covers approximately 39,000 ha, located 27 km west of Concepci—n del Oro district and the northeastern portion of Zacatecas State, Mexico. The SONARtrac systems will provide volumetric flow measurements on critical slurry lines.

Peñasquito is a development project that is owned by Goldcorp ( and will be Mexico’s largest open pit mine. The project consists of two open pits – Peñasco and Chile Colorado. Annual production over the life of mine (estimated at 22 years) is expected to average approximately 500,000 ounces of gold, 31 million ounces of silver and over 400 million pounds of zinc. In December 2008, new reserves were calculated using the latest exploration data and the deposit now contains 17.4 million ounces of proven and probable gold reserves, 4.6 million ounces of measured and indicated gold resources and 5.3 million ounces of inferred gold resources. In addition, Peñasquito contains 1,045.7 million ounces of proven and probable silver reserves, 369.7 million ounces of measured and indicated silver resources and 395.1 million ounces of inferred silver resources. Significant quantities of zinc and lead will also add to the reserve base. The deposit remains open to the north, east, and at depth. Exploration drilling remains in progress.

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. SONARtrac non-intrusive flow monitoring systems make no contact with the slurry and can be removed and reinstalled when it is necessary to replace the pipe. As well, SONARtrac systems demonstrate a very stable output in the presence of a variety of ores, and demonstrate superior levels of performance. This passive, sonar-based technology enables measurements of single phase and multiphase fluids, as well as slurries, with the same level of accuracy and performance.
