ITEM 8.01 Other Events

RELEVANT EVENT

Mexico City, September 22, 2014, Buenavista del Cobre, S.A. de C.V. (the “Company”), a subsidiary of Southern Copper Corporation, reports that there was no second spill of acid copper sulfate solution at any of the reservoirs at the Buenavista del Cobre mine.

As a consequence of heavy rains triggered by Hurricane Odile, the Tinajas 1 and Tinajas 2 reservoirs at the mine were overflowing with rainwater. Such incident was timely communicated to the relevant authorities on September 18, 2014. The Mexican Environmental Protection Agency (PROFEPA) has announced that such discharge derives from the rainwater and contains some ferrous elements below hazardous levels, which are not considered a health hazard. (See PROFEPA’s official statement at: http://www.profepa.gob.mx/innovaportal/v/6327/1/mx/aguas_ pluviales _con_elementos_ferrosos_por_debajo_de_la_norma_analisis_de_nuevo_vertimiento_en_buenavista_del_cobre:_profepa.html)

Water testing conducted through September 20th, 2014 by PROFEPA, CONAGUA and the Company reported normal acidity levels in the Bacanuchi and Sonora Rivers.
