Federation

Our Federation Mine is located approximately 10km south of our Hera site. The deposit hosts high-grade zinc, lead, gold, copper and silver mineralisation.

Federation represents the first building block to unlocking our broader potential in the Cobar Basin and was officially opened by the Hon. Minister Courtney Houssos on 11 September 2024.

Ore haulage from Federation to Peak began in Q2 FY25, with the first ore processed in December 2024 and 81kt processed during FY25.

On 27 March 2025, the NSW Department of Planning, Housing and Infrastructure approved a modification (MOD2) to Federation’s development consent. Originally lodged in Q4 FY24, MOD2 enables extended ore haulage hours and increases annual ore transport capacity to 600ktpa. These changes will be key enablers to ramping up production at Federation in FY26.

Following the commencement of development activities in August 2023, 5,400m of lateral development has been completed. Q4 FY25 saw notable increases, with 1,134m developed and 9,051m drilled. Infrastructure delivery tracked closely with the ramp-up schedule. Surface works for ore haulage routes were largely completed. The Hera water management dam became operational in Q2 FY25, power upgrades and the commissioning of a primary ventilation fan supported
deeper development, and the mobile maintenance workshop neared completion by the end of Q4 FY25. Road intersection upgrades are scheduled for FY26 to facilitate higher haulage volumes to Peak in line with MOD2 provisions.

The Federation Project team also demobilised in Q4 FY25, signalling the shift to full operational control.

In FY26, the focus at our Federation Mine will be on ramping up production, increasing stoping tonnes, advancing decline development to establish deeper drilling platforms and the transition to commercial production.
