Investment in Minera Yanacocha S.R.L.-

The Group, through its subsidiary Compañía Minera Condesa S.A., has an interest of 43.65 percent of Minera Yanacocha S.R.L. (hereinafter “Yanacocha”). Yanacocha is engaged in gold production and exploration and development of gold and copper in their own concessions or owned by S.M.R.L. Chaupiloma Dos de Cajamarca (subsidiary of the Group), with which signed a contract of use of mineral rights.

The Quecher Main project of Yanacocha, an oxide deposit, which is a new open pit within the existing footprint of Yanacocha which began operating in October 2019. This project will add oxide production at Yanacocha and will extend the life of the Yanacocha operation to 2027. During 2020, the ounce production of the project was 55,413 ounces.

In addition, Yanacocha owns the Conga project which consists in two deposits of gold and porphyry of copper located at northeast of Yanacocha operating area in the provinces of Celendín, Cajamarca and Hualgayoc (Peru).

Because of local communities and political protests for potential water impacts of the project development activities and construction, the projects are suspended since November 2011. To date, Yanacocha’ s management has been making only water support activities recommended by independent experts, mainly the construction of water reservoirs, before carrying out any development project.

In December 2017, Yanacocha acquired 63.92 million of shares (share of 5%) held by International Finance Corporation (IFC) in Yanacocha, for an amount of US$47.9 million. In June 2018, Sumitomo Corporation (Sumitomo) paid US$48 million for the five percent stake in the ownership interest in Yanacocha for the proportion held prior to the repurchase of the IFC’s ownership stake in December. As a result of that acquisition, the Company recognized a lower value with respect to Yanacocha’s equity participation.

In February 2020, the Supreme Court resolution was published, whereby Yanacocha received notification of an unfavorable result in the Tax Dispute related to the amortization of contractual rights (see note 29(d)) for which Yanacocha recorded a liability in term of tax payable for US$8.1 million and recorded interests and penalties for US$21.0 million in its financial statements as of December 31, 2019. The potential outstanding liability in this matter amounts to US$61 million. During 2020, Yanacocha registered an amount of US$2.1 million related to workers participation related to this resolution. Yanacocha´s Management concluded that is not possible to fully predict the outcome of this litigation.
