Item 8.01 Other Events

The Form 8-K filed on June 9, 2006, Topic: Closure of La Caridad

Southern Copper Corporation (the “Company”) announces that its subsidiary Mexicana de Cobre, S.A. de C.V. (“Mexcobre”) has been forced to close its copper mine at La Caridad and its lime plant at Agua Prieta both located in the state of Sonora in Mexico.

The Company and Mexcobre have been forced to take this step as a result of the continued strike and illegal blockage of the entrance to the La Caridad mine since March 24, 2006 by a group of workers and the resulting vandalism and theft. The Company and Mexcobre have attempted to work through official channels to resolve this dispute. The lack of secure conditions despite assurances from the Mexican Federal Goverment, has resulted in the continued blockage of access to La Caridad for 78 days. At this time, the Company does not believe the dispute will be resolved in the near future and has been forced to suspend operations at the La Caridad mine and the Agua Prieta plant to avoid further losses and possible new conflicts.

The Company and Mexcobre regret being forced to make this decision. The Company has determined that it has no choice but to close the La Caridad mine and the Agua Prieta plant and terminate its individual labor agreements and collective bargaining agreements in accordance with the Mexican federal labor law. The Company’s subsidiary Mexicana de Cananea, S.A. de C.V. has declared force majeure on its June and July Cananea copper mine delivery contracts. The Company believes that the issues that need to be resolved are internal union issues on a national level which have nothing to do with contractual labor relations between the Company and its workers.
