Authorities in Chile are cracking down on water use by mines within the driest desert on earth, threatening future provide within the prime copper-producing nation.

On Friday, Chile’s environmental company SMA charged BHP Group’s Escondida for allegedly drawing extra water than allowed for nearly 15 years in a transfer that would outcome within the lack of its allow, closure or a high-quality. Simply to the south, state-owned Codelco has suspended a deliberate growth of its Salvador mine till it could possibly resolve a swimsuit filed by the State Protection Council towards the venture’s proposed use of water.

BHP has 10 days to current a compliance program in response to the cost.

Escondida rejected the allegations, saying in an emailed assertion that it ceased extraction from aquifers on the finish of 2019 and now runs solely with desalinated water.

“Escondida has by no means exceeded the restriction of 25 centimeters established as most acceptable lower of the aquifer stage within the monitoring space of the wetlands of Tilopozo,” it mentioned.

The swimsuit towards Salvador’s growth threatens future provide given the venture is required to replenish falling ore grades at Codelco’s smallest and least worthwhile operation.
