• Ground truthing confirms target Mesozoic Algebuckina Sandstone exposed at desired elevation
• Encouraging modal analysis results with Valuable Heavy Minerals (VHM) ranging from 51.6% to 67.1%
• Sachet logging confirms VHM assemblage of 40% to 70% with high combined rutile and zircon content

Iron Road Ltd is pleased to advise that a comprehensive reconnaissance mapping and surface sampling program has been completed at the Irria Prospect by HM expert Ian Warland, Iron Road's independent Geological Consultant. Ground truthing confirms that the Algebuckina Sandstone, a potential host of heavy minerals, occurs at an elevation of 160-190m ASL at the Irria Prospect. The reconnaissance HM sampling program involved the collection and analysis of 20 pan concentrated sediment samples. Modal analysis returned highly encouraging results in the -400µm fraction, with Valuable Heavy Minerals (VHM) ranging from 51.6% to 67.1%, dominated by titanium minerals and with a notable relative presence of higher-value zircon. Sachet logging of the -400µm fraction confirmed the VHM component ranging from 40% to 70%, averaging 55% and dominated by ilmenite, rutile, zircon, and leucoxene. Rutile and zircon combined averaged 24% of the VHM present in the samples, which is encouraging due to the higher value of these minerals compared to ilmenite. The reconnaissance program has validated the prospectivity of the Irria Prospect, with a low-impact drilling and sampling program now approved and a drilling contractor appointed, with mobilisation planned for 1 December 2025.
