Westgold Resources (ASX:WGX) issued fiscal 2027 gold production guidance of 385,000 to 425,000 ounces at an all-in sustaining cost of AU$2,980 to AU$3,380 per ounce, according to a Wednesday filing with the Australian bourse.

The company also provided an updated three-year outlook to increase group gold production to between 460,000 and 510,000 ounces in fiscal 2029.

Planned investment in Westgold's largest mines is expected to lift production, improve mill utilization, and reduce its all-in sustaining cost to AU$2,640 to AU$3,000 per ounce by fiscal 2029.

Group processing capacity is expected to increase to more than 7 million tonnes per annum by fiscal 2029 through sequenced brownfield expansion of the Cue and Meekatharra hubs, the company said.

Its shares fell 5% in recent Wednesday trade.
