Aurumin Limited (ASX: AUN) ('Aurumin' or 'the Company') is pleased to provide an update on exploration activity at its 100% owned Central Sandstone Gold Project.

Aurumin's first drilling programme at Sandstone is progressing well with the reverse circulation (RC) portion completed and the first diamond drill hole now through the tonalite target. Diamond drilling is seeking to both extend and better define the existing inferred 14.2Mt @ 1.1g/t Au (500koz Au) Two Mile Hill underground resource. The first diamond hole has intersected numerous occurrences of mostly fine visible gold through the tonalite, and the core is currently being processed on-site in preparation for assay.

All assays from the RC portion of the programme, focused on extending the higher grade portion of the Shillington deposit along a structural control, are currently at the assay laboratory. Aurumin's auger programme, infilling and extending a 2021 programme, has increased resolution across six known target areas and highlighted five new targets. The increased resolution provides information to better assess and potentially advance these prospects towards drill targets.

Aurumin's Managing Director, Brad Valiukas, commented: 'We have a two-pronged approach that is progressing well at Sandstone. The first part is to make the most of the 500koz Two Mile Hill Resource. We are diamond drilling currently with some specific goals and it's always pleasing to be intersecting visible gold. The second part is to make the most out of the tenement package that we have at Sandstone. The auger programme is part of that, exploring for new deposits just a couple of kilometres from existing infrastructure. Another five targets is a great outcome and there are still further areas to be assessed with another programme. '

DIAMOND DRILLING - FIRST HOLE COMPLETE

As per the announcement of 27th May 2022 Aurumin has commenced the diamond portion of the programme targeting the Two Mile Hill Complex. Aurumin's first diamond hole at Sandstone (SN_TM_RD_22_0002) has completed drilling through the tonalite on 08/06/2022 at a down hole depth of 562m. The target tonalite stock was intercepted 20m earlier than modelled, giving confidence to Aurumin's working interpretations. The hole has returned numerous occurrences of visible, mostly fine gold, typically associated with galena in brittle shallow dipping quartz and quartz-carbonate veins and fractures.

AUGER RESULTS RETURNED

Auger results have now been received and compiled from the programme completed at the Central Sandstone Project in April. Results have confirmed and supported the six targets highlighted in auger work completed in the 2021 campaign, increasing the resolution of anomalism at Two Mile West, Mt Klempt, Wirrimina North, Nugget Patch, Three Mile and Nungarra Town. The increased resolution provides information to assess better and advance these prospects towards drilling. New targets have been identified at Ridge North, Two Mile North & East, McClaren West, and on the Old Town Well Trend with gold grades up to 1,860ppb. These targets will be further assessed for the next stage of work. Multielement analysis is in progress to better understand potential pathfinders and allow comparison with existing deposits.
