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:

Today the Julcani Mining Unit will restart its operations, having adequate security conditions and social support, thanks to the joint work with the neighboring communities of the Mining Unit, who expressed their rejection of the acts of violence carried out by a group of people outside the area of influence of the Mining Unit.

Both the surrounding communities and the different unions publicly expressed their rejection of the acts of vandalism carried out at the Mining Unit, after which they issued a formal request to the Company to restart operations at the Julcani Mining Unit.

Buenaventura reiterates its rejection of any act of violence and shows its appreciation to the communities surrounding the Julcani Mining Unit for their solidarity, support and commitment to an operation that has worked hand in hand with the local population for 70 years.
