Corporación Nacional del Cobre de Chile (Codelco) has resumed operations at its Distrito Norte mines after the company had to shutdown activities due to torrential rain and flooding.
The heavy rain is said to have caused widespread flooding in various parts of northern Chile.
Wall Street quoted the Chilean state-owned copper producing company, saying it halted operation at its División Salvador in the Atacama region, as safe operating conditions still could not be guaranteed.
Due to the rains Codelco closed operations at some open-pit mines as a precautionary measure due to slippery roads. The company's processing plants were working.
The company's operations in Chuquicamata, Ministro Hales, Radomiro Tomic and Gabriela Mistral divisions in the Distrito Norte, which were affected due to the slowdown, now have normal water and energy supplies.
Chile Deputy Interior Minister Mahmud Aleuy said the torrential rain forced Chile's Government to declare a state of emergency in the northern regions of Atacama and Antofagasta.
Aleuy told Bloomberg News: "We still don't have the number of those affected, though we do know there are 800 people in shelters in Atacama and another 684 in Antofagasta."
Lundin Mining was also compelled to cease operations at its Candelaria mine and Pan Pacific Copper also closed its Caserones mines.
Following the downpour, Anglo American's Mantoverde plant was closed by power cuts.
