A bloc of 300 organizations, including community action boards, civil society nature reserves and environmental groups, declared Minera de Cobre Quebradona and AngloGold Ashanti as 'persona non grata' in southwest Antioquia.[^3] The signatories refused to participate in any socialization activities the company proposes.[^7]

The declaration comes as Colombia's National Mining Agency (ANM) extended the exploration phase for the Quebradona copper project in Jericó, Antioquia, until 2027.[^2] Minera de Cobre Quebradona, a subsidiary of AngloGold Ashanti, began a new community dialogue process in the region to prepare a new Environmental Impact Study (EIA) for the project.[^4] AngloGold Ashanti is developing the Quebradona underground copper mine project in Jericó, focused on copper, gold and silver.[^5][^6]

Opponents of the project argue that studies by Corantioquia, the University of Antioquia, and the Colombian Geological Service warn of a vital aquifer recharge zone in the area, putting water sources at risk from deep mining.[^1]
