In August 2015, the Peruvian environmental leader Milton Sánchez Cubas, Secretary-General of the Plataforma Interinstitucional Celendina (PIC), was accused of disturbances by the Mining Company Yanacocha with operations in Peru. In July 2015, Milton Sanchez and other community leaders demonstrated against the Conga Mining Project, developed by Minera Yanacocha, for considering it a threat that put at risk the quantity and quality of water, life, agriculture, and the environment. On 26 May 2019, the first Criminal Appeals Chamber of the Superior Court of Justice of Cajamarca acquitted Milton Sánchez Cubas of the Yanacocha company's charges.
