IAMGOLD Corp. expects production from its Westwood gold mine in Quebec of 100,000 to 125,000 ounces per annum during its three to four year ramp-up period, based on preliminary sequencing.

All-in sustaining costs are expected to range from US$1,125 per ounce sold to US$1,225/oz, according to a Dec. 12 news release.

Annual steady-state output following ramp-up at Westwood is targeted at between 130,000 and 145,000 ounces at all-in sustaining costs of between US$1,000/oz and US$1,100/oz.

The mine life is expected to go beyond 2030, with potential to extend further.

The company will update the mineral reserves and resources and the National Instrument 43-101 life-of-mine plan for Westwood in the second quarter of 2020.
