Ref: Notice of Material Information

Dear Sirs:

As required by the Regulation on Material and Reserved Information (Resolution SMV No. 005-2014-SMV/01), we inform you that:

On the date hereof, Compañia de Minas Buenaventura S.A.A. (“Buenaventura” or “the Company”) entered into certain definitive agreements with Newmont Corporation (“Newmont”) to sell its total stake in Minera Yanacocha S.R.L. (“Yanacocha”), held through Compañía Minera Condesa S.A., which represents 43.65% of Yanacocha’s equity, for a consideration equal to US$ 300 million plus certain contingent payments of up to US$ 100 million linked to the production of the sulfides project that Yanacocha is planning to develop and as well as to future increases in mineral prices.

Additionally, the Company’s subsidiary Sociedad Minera de Responsabilidad Limitada Chaupiloma Dos de Cajamarca (“Chaupiloma”) will transfer all of its mining concessions to Yanacocha, in exchange for a royalty in an amount equal to the royalty currently perceived from such operations by Chaupiloma as well as two additional royalties in respect of future projects in certain concessions.

Further, Newmont will transfer its quotas in Minera La Zanja S.R.L. to Buenaventura, in exchange for a royalty in respect of such mining unit’s future production. Newmont will also make a one-time payment to the Company in an amount of US$45 million, as partial contribution to the future costs relating to the closure plan for the La Zanja Mining Unit.

With these transactions, Buenaventura seeks to focus on its asset portfolio, decrease its leverage and increase shareholder returns.

Yours faithfully,

Daniel Domínguez Vera

Stock Exchange Representative
