Correction to Previous Announcement

• Errors in intersections highlighted in the body of the announcement
• Incorrect grid coordinates in the drillhole location table in Appendix 1
• Corrected drillhole locations and drilling details provided

Rox Resources Limited (ASX: RXL) has issued a correction to a previous ASX announcement titled 'Drilling identifies high-grade ounces outside of mine plan', released on 21 April 2026. The announcement contained errors in the intersections highlighted in the body of the announcement, as well as incorrect grid coordinates in the drillhole location table in Appendix 1. The company has provided the corrected drillhole intersections and locations, noting that the significance of the findings remains unchanged, as they continue to derisk initial production fronts scheduled for late 2026 and indicate substantial potential to increase production with additional levels and stopes from the initial mine plan. The errors in Appendix 1 arose through the misreporting of drillhole location coordinates using the mine operational grid instead of MGA. The company has provided the corrected collar locations and drilling details, as well as the mine grid to MGA conversion. There were no other changes to the JORC Table used in the original announcement.
