Announcement PDF MRG Metals Limited ABN: 83 148 938 532 / ASX Code: MRQ Phone: +61 3 5330 5800 / Fax: +61 3 5330 5890 12 Anderson Street West, Ballarat VIC 3350 / PO Box 237 Ballarat VIC 3353 www.mrgmetals.com.au / info@mrgmetals.com.au ASX ANNOUNCEMENT 17 September 2026 Clarification and Additional information in relation to ASX Announcement of 15 September 2026 “Adriano Rare Earth – Growing Mineralized Footprint” MRG Metals Limited (ASX: MRQ) (“MRG” or “the Company”) wishes to supply clarification and additional information as requested by the ASX in relation to an announcement made to the marken on 15 September 2026 “Adriano Rare Earth – Growing Mineralized Footprint”. In the announcement, the following statements were made “Visually estimated grade in these step out holes is consistent with visually estimated auger grades observed in previous holes within the footprint, that later recorded high grade HMS in assays(refer Figure 4)” and “The visual mineralisation discussed will be confirmed via laboratory analyses. There is no guarantee on what exploration will uncover in terms of the dimensions / mineralisation of the alluvial deposits. Positive results will result in additional infill / step-out drilling”. The comments referred to visually estimated Total Heavy Mineral (THM%) grades of samples as estimated by field staff during exploration. MRG did not report the visually estimated grades, or show the results on a map, but have been advised to supply this information to augment the announcement. The auger borehole details (coordinates, dip, azimuth) for the 20m and 200m grid areas were reported in the main body of the announcement. The hole ID, individual sample intervals and sample numbers, as well as the visually estimated THM% grade for each sample, are shown in Table 1 for the 20m spaced grid and Table 2 for the 200m grid below. Samples with visually estimated THM% of ≥4% are highlighted in red. Figure 1 shows the holes for the 20 and 200m grid, as well as the viasually estimated grades. Subject to a current capital raising, MRG anticipates being able to report the laboratory assay results from this program late in Q4 2026 or Q1 2027.
