Summary
St Barbara Limited announced a significant increase in the Mineral Resources Estimate for their 15-Mile Processing Hub Project, rising by 20% to 2.5 Moz. This update incorporates revised geological interpretations, additional historical drilling data, and employs Ordinary Kriging for greater accuracy due to enhanced data density and confidence. Validation included a comprehensive review of historical drilling data from the 1980s. The updated estimate supports the potential for larger optimised pit shells and indicates high gold recovery potential through strong metallurgical results. Further studies and reserve estimates are planned for completion in FY27.
