Fatal victims

• - On May 5, 2006, a conflict over better salaries between the mining company and its workers led to the blocking of access to the mine and the subsequent police repression in which the student Joel Martel Castromonte (25) and the miner Guillermo Tolentino Abad (42) were murdered in Huallapampa.[7]​[8]​[9]​ Additionally, 20 people were injured.[10]​.

• - On September 19, 2012, a conflict over water between the mining company and residents of the Mareniyoc hamlet in the Jangas district ended in a confrontation where Nemesio Poma Asnate (57) died and 4 other community members were injured along with 3 members of the police forces.[11]​[12]​ Due to what happened, mining operations were suspended for a day for mourning. The corporate affairs manager, Gonzalo Quijandría Fernández, stated that this decision would not affect monthly production.[13]​.

Pierina has been going through the “progressive closure” stage since 2015, which will last until 2021 or 2022, and involves the dismantling of the infrastructure and the revegetation of the pit. Then comes the final closure, which includes chemical stability for five or six years. And later will come the monitoring phase, which goes beyond 2026.[14]​.
