Cerro Negro Norte opened again in 2010–2014 and in 2021 it had a production capacity of 4 million tons of iron.[4][1] It produces iron ore concentrate that is transported as pulp in pipelines to the port of Punta Totoralillo located 55km northwest of the mine.[1][5] The mine stores and processesiron ore from smaller mining companies.[1]
In 2014, plans for a desalination plant to provide water for mining operations at it and other mines was announced.[6]
As of 2025 Cerro Negro Norte was the newest of the mines owned and operated by Compañía Minera del Pacífico (CMP).[1] In early 2025 Compañía Minera del Pacífico submitted a plan to the Environmental Assessment Service to increase iron production capacity at the mine from 4 to 4.5 million metric tons.[1] Among other things the project seeks to improve are the conminution and concentrating plants.[7]
