Aurumin Ltd (ASX:AUN) has logged numerous occurrences of mostly fine visible gold in its first diamond hole drilled through a tonalite target at Central Sandstone Gold Project in Western Australia.
The company's diamond drilling is aiming to extend and better define the existing inferred 500,000-ounce Two Mile Hill underground resource.
Furthermore, Aurumin’s auger program, infilling and extending a 2021 program, has increased resolution across six known target areas and highlighted five new targets.
“Intersecting visible gold”
Aurumin managing director Brad Valiukas said: "We have a two-pronged approach that is progressing well at Sandstone.
“The first part is to make the most of the 500,000-ounce 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 program 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 program."
Diamond drilling progress
Aurumin's first drilling program at Sandstone is progressing well with the reverse circulation (RC) portion completed and the first diamond drill hole now through the tonalite target.
Its first diamond hole at Sandstone (SN_TM_RD_22_0002) completed drilling through the tonalite on June 8, 2022, at a down hole depth of 562 metres
The target tonalite stock was intercepted 20 metres earlier than modelled, giving confidence to Aurumin’s working interpretations.
The hole returned numerous occurrences of visible, mostly fine gold, typically associated with galena in brittle shallow dipping quartz and quartz-carbonate veins and fractures.
Visible gold towards the end of the hole supports mineralisation being open below the base of the existing 500,000-ounce resource.

Auger results
Aurumin’s auger program highlighted six targets in 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 1,860 parts per billion.
These targets will be further assessed for the next stage of work.
Furthermore, a multi-element analysis is in progress to better understand potential pathfinders and allow comparison with existing deposits.
