Yari Confirms Low-Ash Coal Quality at Rolleston South, Bowen Basin, Qld
Coal quality testwork confirms Rolleston South can produce a low-impurity, low-ash coal product that typically commands stronger pricing and broader export market acceptance
• Detailed coal quality testwork completed on core from drillhole RSC015C targeting the key “B” and “D” seams of the Bandanna Formation
• Results confirm very low raw ash and favourable washability characteristics, supporting the potential for a low-ash export product
• Washability simulations indicate a 7–8% ash product may be achievable at approximately 85% yield through conventional coal preparation
• Low total sulphur (0.35%) and low total phosphorus (0.07%), further support potential export market acceptance
• Coal quality data underpinned the recently reported maiden Indicated Resource of 33.7 Mt, contributing to a total Resource of 222.9 Mt
• Quality assessment supports potential for an export-quality thermal or semi-soft metallurgical product, subject to further confirmatory work
• Yari continues to evaluate strategic development and partnership pathways for Rolleston South within the Southern Bowen Basin
