Yanacocha Suspends Construction at the Conga Project in Agreement with the Government of Peru

Compañía de Minas Buenaventura S.A.A. ('Buenaventura? or 'the Company?)
(NYSE: BVN; Lima Stock Exchange: BUE.LM), Peru′s largest publicly-traded
precious metals mining company announced today that Minera Yanacocha
S.R.L. (Peruvian gold producer held by Buenaventura 43.65%, Newmont
51.35% and the IFC 5%) , in agreement with the government of Peru, has
suspended construction activities at the Conga project (or the
'Project?) in Peru for the safety of employees and community members.
During the past month, the Conga project has experienced intermittent
work stoppages as a result of ongoing protests in the region. Beginning
in October 2011, anti-mining activists expressed concerns about
perceived impacts of the Project on the local water supply. The Conga
Environmental Impact Assessment was approved in 2010 after extensive
review by the Peruvian government, which included significant engagement
and consultation with local communities.

Buenaventura considers this a prudent decision in order to reestablish
law and order in the Cajamarca Region that is under social unrest. The
Company believed that Conga is a feasible mineral deposit and that the
well being of the people in Cajamarca moving forward will depend on the
development of this and other mineral deposits in the Region.
Buenaventura believes that Yanacocha should continue working hard to
develop the social acceptance of the project.

Mr. Roque Benavides, Buenaventura′s Chief Executive Officer, said:
'Suspending construction activities in Conga does not mean that we do
not believe in the project. We think this is the best thing we can do
for the people in Cajamarca and for the country. Buenaventura is
committed to Peru and ?will keep on working enthusiastically to develop
new projects with a better social and environmental understanding in
Peru.'
