Preliminary Economic Assessment Completed for San Javier

DENVER, CO - Constellation Copper Corporation reported positive results from an independently prepared Preliminary Economic Assessment ("PEA") or scoping study of its San Javier Copper Project that has recently been completed by Independent Mining Consultants ("IMC") of Tucson, Arizona. Also participating in the preparation of the PEA is KD Engineering of Tucson and Golder Associates of Denver, Colorado. The San Javier Project is located about two hours drive east from Hermosillo, Sonora and is immediately adjacent to Mexican Highway 16, the major highway between Hermosillo and Chihuahua City.
The PEA evaluates the potential of the 100% Company owned or controlled San Javier Project to be a significant producer of LME Grade A copper cathode using conventional mining, leaching and recovery methods. The PEA estimates the capital and operating costs for an integrated facility in which copper-bearing material is mined primarily from an open pit on the main Cerro Verde deposit, crushed to a nominal -12 mm (-1/2 inch) size and then placed via conveyors onto a conventional heap leach pad. The material will be leached using dilute sulfuric acid with the resulting copper-bearing solutions being passed through a solvent extraction and electrowinning plant to recover the copper as saleable cathodes.
The PEA concludes that the Project is both technically and economically feasible and recommends that the Project be advanced towards a Feasibility Study.
