South32 Ltd. said April 6 that mining at its Cannington silver-lead-zinc project in Queensland, Australia, was temporarily stalled by an underground fire that damaged the load-out and shaft haulage infrastructure, lowering the projected output from the mine for the year.

The company said extraction of the higher-grade silver-lead stope 60L will be delayed due to remediation work that will be done over a four-week period.

South32 also said it lowered its payable production at Cannington to 16.5 million ounces of silver, 135,000 tonnes of lead and 70,000 tonnes of zinc this year based on a revised mill throughput of approximately 3.1 million tonnes.

Previously, the mine was expected to produce 19.1 million ounces of silver, 163,000 tonnes of lead and 80,000 tonnes of zinc for the year.
