LIMA, March 27 (Reuters) - Peru's Buenaventura

, one of the country's largest miners of precious

metals, on Wednesday said it added two executives from Chile's

Antofagasta ( ANFGF ) to its board of directors following a

partnership that began late last year.

The new members are Ivan Arriagada, Antofagasta's ( ANFGF ) chief

executive, and Andronico Luksic, Antofagasta's ( ANFGF ) vice president of

development, Buenaventura said in a statement.

They will join another seven members on Buenaventura's

board of directors.

Antofagasta ( ANFGF ) acquired a 19% stake of Buenaventura in

December.
