Mineral Resource and Ore Reserve Statement as at 31 December 2023

Managing Director and CEO Andrew Strelein said “We are pleased to provide this annual update to St Barbara’s Mineral Resource and Ore Reserve Statement showing overall Mineral Resources at Simberi and Atlantic has grown from 5.9 Moz to 6.7 Moz. This growth has primarily come from Simberi and this is before any inclusion of results from the ongoing FY24 program.”

“An updated Statement is planned for the end of FY24 and will incorporate results available from the resource definition program where we are targeting an upgrade of 1.0 Moz from Inferred to Indicated Mineral Resource.”

“Our Mineral Resource position of 6.7 Moz is incredible for a Company of our market capitalisation. We recognise that the value proposition for St Barbara lies in demonstrating the development potential of these projects and we are moving quickly on the respective work programs.”
