Recent Drilling Intersects Significant Coal at Rolleston South Coal Project
• Three recently drilled CSG wells (Rougemont 3, 5 & 6) on Yari’s tenure and freely available through a data-sharing agreement, all encountered notable coal seams (up to 3.5m thick) in the D seam horizon
• This is extremely encouraging, as the newly drilled CSG wells are proximal to the Rolleston South Coal Project’s existing delineated 151 Mt Inferred Resource
• Preliminary interpretations by Yari’s geology team, subject to ratification by geological modelling, suggests there is significant potential to expand the existing Inferred Resource
• Results from updating the resource model with the fresh data from the CSG wells will be released once complete
• The Board is progressing securing regulatory approvals for the inaugural drilling campaign, while mapping out a clearer path to market, given Glencore’s Rolleston Mine is only 15km north-west from the Rolleston South Coal Project
