Aeris lifts FY27 growth budget; Constellation ore hits mill late Q3

At Tritton, first-half grades will run lower and weigh on output while the mill processes ore from the Murrawombie open pit and the Budgerygar and Tritton underground mines. Production strengthens in the second half once Constellation's sulphide ore reaches the mill. By the final quarter of FY27, roughly 45% of mill feed is expected to come from the pit's high-grade supergene and primary ore, the company said, lifting feed grades.

Growth capital at Tritton funds infrastructure and capitalised waste stripping at Constellation, with a tailings dam lift and electrical works in the budget. Studies at Mallee Bull are also planned. Aeris will continue an aggressive resource definition drilling campaign at Tritton to convert the large inferred mineral resource defined in FY26 into indicated resources, the basis for future ore reserve consideration. Surface greenfields exploration will search the wider package for another Constellation-style discovery.

Cracow's gold output is expected to decline year on year because of lower forecast grades, despite similar mining and processing volumes. Exploration spending at the mine rises more than 50%. Drilling at the Golden Plateau project extends beyond the 14,000 metres committed in FY26, and a third underground rig will target new high-grade ore shoots at the Western Vein Field. Sustaining capital will also rise because the company is upgrading underground equipment to support a longer mine life.
