Ref.: Notice of Material Information

Dear Sirs:

Through this notice and in accordance with Article 16.1 of the Regulation on Material and Reserved Information, SMV Resolution No. 005-2014-SMV-01, we inform you that:

Compañía de Minas Buenaventura S.A.A. (“Buenaventura”) is pleased to announce that S&P Global Ratings (“S&P”) has initiated credit coverage of the company and has assigned it a rating of BB-, with a stable outlook. This rating reflects an increase in production, a greater diversification of operations, and a low level of leverage.

S&P highlights Buenaventura’s projected production growth, driven by the restart of Uchucchacua Yumpag. Additionally, S&P also highlights that Buenaventura benefits from a diversified portfolio of mines and investments, such as Cerro Verde, that produce both precious and base metals, as well as sound leverage management and an adequate capital structure.

This new credit rating reaffirms Buenaventura’s commitment to generating greater value for its shareholders. Our efforts are focused on mitigating the risks associated with the construction of San Gabriel, complying with the established deadlines and CAPEX, and further optimizing the cost reduction of our operations to increase profitability and maintain a sound financial position.

Sincerely,

DANIEL DOMINGUEZ VERA

MARKET RELATIONS OFFICER

COMPAÑIA DE MINAS BUENAVENTURA S.A.A.
