700 000 oz, reflecting the suspension of operations at the Rosebel mine in response to Covid-19 being detected among workers.
Operations at the mine in Suriname were halted on June 12. The suspension was lifted on July 24, once national health authorities confirmed it was safe to do so.
The Toronto-listed miner, which on Wednesday published its second-quarter results, also revised up its 2020 cost of sales guidance to between $990/oz and $1 030/oz, from between $955/oz and $995/oz previously, owing to lower production volumes.
The 2020 all-in sustaining cost (AISC) an ounce was maintained at $1 195 to $1 245.
