Northern Star Resources Ltd. produced 211,553 ounces of gold in the first quarter of its fiscal 2020, decreasing from 229,136 ounces produced a year ago.
Gold sales fell to 184,005 ounces from 212,682 ounces, while all-in sustaining cost increased to A$1,493 per ounce from A$1,226/oz.
Production and costs during the quarter stemmed from lower-grade mining sequences and scheduling, Northern Star said Oct. 17. It expects costs to decline following access to new mining zones and a percentage increase in stoping tonnes relative to the total processing tonnes.
The company said the strong performance of its Kalgoorlie and Jundee operations in Western Australia helped it generate underlying free cash flow of A$28 million during the quarter, despite spending about A$43 million on growth and exploration.
Northern Star said it made significant progress to expand the processing plant capacity at its Pogo gold mine in Alaska, with mine development rates now on the cusp of hitting the increased monthly target of 1,500 meters.
