Sipa Resources Limited has released promising Nuckulla Maiden RC drilling results at its South Australian Nuckulla Hill Gold Project, including high-grade intercepts confirming exploration potential at the Sheoak and Bimba prospects.
Strong Intercepts Recorded at Sheoak Prospect
RC drilling underway at the Nuckulla Hill Gold Project in South Australia
The Sheoak Nuckulla Maiden RC drilling produced many intersections of gold in seven holes tested across 1,022 metres. The highlight was 16 metres at 5.6g/t gold from 68 metres in hole NHRC022, which included 4 metres at 16.2g/t and an additional 4 metres at 4.4g/t.
There were additional intercepts of 16 metres at 2.2g/t gold from 60 metres with 4 metres at 5.1g/t, and 12 metres at 1.3g/t gold from 120 metres. These intercepts confirm the presence of high-grade zones in a broad system of mineralisation hosted in the Yarlbrinda Shear.
The company noted that mineralisation at Sheoak remains open in the north, south, and down-dip, and thus there is room to expand. The fact that higher-grade intercepts occur within broader anomalous zones highlights the scale potential of the Nuckulla Hill Gold Project.
Extension of Mineralisation Beyond Historical Work
High-grade gold intercepts were returned from Sheoak prospect drilling
Sipa Resources Limited reported that hole NHRC022 stretched mineralisation by at least 50 metres to the northwest. Significantly, no intervals of high-grade from this hole were encountered in the above historical 1990s RAB drilling.
This discovery indicates that earlier shallow drilling may not have fully probed gold mineralisation. The company asserted that areas earlier believed to be extensively tested or prospect zones have the potential to still contain mineralised zones at depth. The discovery leaves room for more exploration across the entire project area.
Bimba Prospect Drilling Results
Together with Sheoak, six holes with a cumulative 662 metres were drilled on the Bimba prospect. Whilst no +1g/t gold intercepts were attained, there were wide anomalous zones of gold. Some results were 4 metres at 0.9g/t gold from 112 metres and 4 metres at 0.7g/t gold from 136 metres.
Sipa Resources Limited noted mineralisation at Bimba to be potentially oriented northwest-southeast, a direction not adequately tested in this campaign. The company intends to use this orientation for subsequent drilling phases. Identification of broad anomalous zones is indicative of potential for further definition in the Yarlbrinda Shear.
Future Drilling and Sampling Programs
Sipa Resources Limited said follow-up drilling of the Nuckulla Hill Gold Project would commence within the coming week. The following campaign will include 4,000 to 5,000 metres of aircore drilling and selective RC holes to test further targets.
The project will sample Sheoak, the significant Tunkillia North gold-in-calcrete anomaly, and the historic assays at Arcoady. Resamples of the current campaign of one metre will also be grabbed and analysed further. Assays are to be returned within four to six weeks.
In addition to drilling, pre-advanced-stage and regional targets have soil sampling programs planned out over them to expand exploration priority. This systematic procedure is applied for building a pipeline of prospective targets in the broader project district.
Geological Setting and Regional Positioning
Nuckulla Hill Gold Project is hosted within the Yarlbrinda Shear Zone, host to Barton Gold’s 1.6Moz Tunkillia deposit. The project hosts a number of underexplored prospects such as Sheoak, Bimba, and Tunkillia North.
Previous exploration in the 1990s focused mainly on shallow RAB and aircore drilling. Current RC drilling indicates that the areas of higher grade are below the depth that has been tested from earlier work. This has rejuvenated belief in the overall exploration potential of the Nuckulla Hill Gold Project.
Sipa Resources Limited highlighted its projects’ proximity to mature regional operators, whereas proximity to deposits and infrastructure supports the project’s standing within South Australia.

Market Outlook
Sipa Resources Limited shares (ASX: SRI) finished flat at $0.014 on 28 August 2025 following news of the Nuckulla Maiden RC drilling results. Pending resample assays follow-up drilling, and Tunkillia North updates will be monitored by market players.
The company’s strategy of advancing multiple opportunities within the Yarlbrinda Shear provides an ongoing news stream and exploration upside. Shareholders will likely monitor assay results and drilling success during the next few months.
