Aurumin Limited (ASX: AUN) ('Aurumin' or 'the Company') is pleased to announce final assay results have been returned for the outstanding diamond hole samples and for the RC pre-collar samples of the recently completed Reverse Circulation (RC) and Diamond Drilling programme at its 100% owned Central Sandstone Gold Project. Drilling seeks to both extend and better define the Company's previously reported inferred underground Mineral Resource Estimate (MRE) of 14.2Mt @ 1.1g/t Au for 500koz Au at Two Mile Hill.

Hole SN_TM_RD_22_0001 was drilled using an RC pre-collar to 91.0m depth. From 91.0m drilling was by diamond core to end of hole at 609.3m. SN_TM_RD_22_0001 was designed to further test the northern portion of the Two Mile Hill inferred geological resource at depth.

Aurumin's Managing Director, Brad Valiukas, commented: 'This is another good result and, along with the previously released diamond results, continues to add to the picture at Two Mile Hill. 'Along with the recently completed RC drilling at Shillington, this sets us up to now model the Shillington and Two Mile Hill deposits as a single geological complex, with known grade in the banded iron formation, mafic and tonalite. 'We are commencing an updated resource model, and look forward to releasing the model results and plans for the next round of drilling

DIAMOND DRILLING AND GEOLOGY SUMMARY

Drilling seeks to extend and better define the Company's previously reported inferred underground Mineral Resource Estimate (MRE) of 14.2Mt @ 1.1g/t Au for 500koz Au at Two Mile Hill, with a focus on the tonalite intrusion between 250m and 500m below surface.1 (see Figure 1) The mineralisation at Two Mile Hill is hosted in three geological domains. The majority of the Two-Mile Hill resource occurs within a tonalite intrusion. Mineralisation also occurs within banded iron formation (BIF) beds, and within the basalts that host the tonalite intrusion. The tonalite intrusion is broadly oblate in plan, dipping ~78-degree towards 281-degree. Tonalite hosted mineralisation occurs predominantly as discreet free gold occurrences within a sheeted/stockwork array of narrow quartz veins. The orientation of the sheeted vein array is variable but is on average orthogonal to the estimated axis of the tonalite. There is some variability in the dip direction but on average veins dip shallowly to the north-east. Veins range from 2mm to 900mm but are typically in the order of 20-80mm width. The drilling is designed to test the Two Mile Hill Tonalite volume with drilling approximately perpendicular to the mineralised sheeted vein array. Structural logging and observation in core drilled during this round of drilling has confirmed the dominant vein orientation from previous studies. Within the tonalite and adjacent mafic, contact zone veins with visible gold are usually (though not exclusively) dipping 20-30-degree degrees towards 30-130-degree (striking 300-040-degree). Visually coherent zones of mineralisation, and higher grades are largely consistent with this orientation. This is consistent with the geometry of the BIF unit(s) and overall surrounding lithology, and broadly perpendicular to the direction of drilling
