The San Cristóbal mine, located near the border with Chile, has suspended operations.

The Caribou mine in New Brunswick has been in continuous production since 2015.

Glencore joins peers such as Anglo American, Antofagasta, Codelco and Teck Resources in temporarily closing or slowing some operations.

Analysts at Fastmarkets believe the extended closures and logistical jams could see supply of base metals produced in the region restricted.

Zinc prices have cratered since peaking in January.

The miner said there had been no material impact on production or shipments from any of the company’s operations to date as a result of Covid-19.

The miner is dealing with permitting issues incurred in by the previous owner of the Santa Cruz operation.
