The Vancouver company had suspended work at the mine on April 2 after an earlier occupancy deal expired.
Goldcorp said production at Los Filos is expected to be at the low end of the mine's guidance for between 330,000 and 345,000 ounces due to the lost month.
However, the gold miner reconfirmed its overall company guidance of between 2.95 and 3.10 million gold ounces for the year.
The Los Filos mine has been in operation since 2007 and produced 332,400 ounces in 2013.
The project consists of two open-pit mines and one underground mine.
