Poseidon Nickel (ASX: POS, the Company) is pleased to provide an update on the gold exploration programs at Black Swan.
- Reconnaissance soils sampling has identified several gold anomalies
- Anomalies extend over multiple soil traverses (between 400m to 800m) along the interpreted gold bearing structures
- Wilson’s Prospect – several positive coincident attributes established
- A coherent gold anomaly defined (up to 54ppb Au) that is 1.4km by 1km in size and remains open to the south
- The gold anomaly extents capture the locations of the previously announced gold nuggets and anomalous rock chip samples that graded up to 1.25g/t Au in gossanous quartz veins1,2
- Several historical gold drill intersections with assay results >1g/t Au, including 0.4m @ 6.41 g/t Au2, are also located within the anomaly area, despite only 5% of all historical drillhole samples being assayed for gold
- The layered indicators for gold potential at Wilson’s Prospect point to a highly prospective exploration target as evaluation programs continue
- Gold exploration programs underway
- High priority infill soil and further grab sampling programs are underway to better define soil trends at Black Swan. Infill results will be used to optimise drill targets
- At Lake Johnston, maiden reconnaissance soil surveys have been completed across the newly acquired Mantis tenement and submitted for analysis - results awaiting
CEO, Brendan Shalders, commented, “During August 2024 the Company completed a wide spaced reconnaissance soil sampling program across the entire landholding at Black Swan which was assayed for the full suite of elements.
Soil sample assay results have noted four promising gold in soil anomalies. The extents of the anomalies and morphology appear to be tracing the prospective gold bearing structures throughout the geological sequence at Black Swan which have never been systematically tested for gold.
There is little outcrop at Black Swan thus reconnaissance surface geochemical surveys are considered a cost-effective exploration technique to quickly identify areas of gold anomalism. Due to the significant dilution of the soil profile as it is mainly comprised of sands and clays, the gold values recorded are usually only at low levels (ppb). The importance of a gold in soil anomaly is it often presents a vector to a prospective gold system below, and in its original undiluted setting, maybe at much higher grades, hence drilling is required to effectively test the target.
We are particularly excited about the gold targets that are presenting at the Wilson’s Prospect. Results of the separate work programs to date are showing several positive coincident attributes underpinning the prospectivity for the targets. These include the establishment of a large coherent gold in soil anomaly with a footprint that captures the locations of the previously reported gold nuggets, anomalous rock chip samples and historical drilling intersections grading up to 6.41g/t Au.
Despite the historical gold intersections, only 5% of all drillhole samples at Black Swan were assayed for gold. Given the lack of gold assays and the historical focus on nickel, the gold potential at Black Swan has been somewhat overlooked.
High priority infill soil sampling programs are underway to better define drill targets and progress the planning for low-cost shallow drilling programs.
We are also awaiting the results from the Lake Johnston soil programs completed in early September 2024. Once received and interpreted the company plans to continue to undertake additional programs to progress and established any newly identified gold targets within the portfolio.”
Gold in Soil Anomalies at Black Swan
During August 2024 the Company collected 362 soil samples from a wide spaced reconnaissance soil sampling program over the entire Black Swan tenement package on 800m and 400m space traverses with sampling intervals of between 80m and 160m. The soil samples were tested using the UltraFine+ technique identifying four coherent anomalies across the program (refer Figure 1).
Figure 1: Black Swan gold in soil anomalies
Gold assay results from the soil sampling, tabled in Appendix 1, grade up to 54ppb and present four distinct gold in soil anomalies spread across the Black Swan tenements. Importantly these anomalies correlate to the interpreted secondary structural corridors emanating NNE off the larger north striking Mt Monger Fault (see Figure 2 for interpreted location of Mt Monger Fault).
The Black Swan project is situated within the Boorara Geological Domain which hosts a number of gold mines including the nearby Kanowna Belle, Mungarra and Gordon Sirdar projects, as recently announced in ASX announcement “Gold Prospectivity Enhanced at Black Swan and Lake Johnston” re- released 16 August 2024.

High grade Massive Sulphide Intercepts Confirmed at Oval
HIGHLIGHTS:
- OVD027 confirms the continution of high grade massive sulphide from OVD0211 with an intercept of 6.1 metres of 4.16% Cu, 3.51% Ni, 0.G3g/t E3, and 0.13% Co from G8.2 metres encountered between broader high grade zones of:
- A dense disseminated intercept - 26.2 metres of 0.44% Cu, 0.52% Ni, 0.12g/t E3, and 0.03% Co from 72.0 metres and
- A net textured intercept - 15.3 metres of 1.15% Cu, 0.79% Ni, 0.35g/t E3, and 0.04% Co from 104.3 metres;
- A high grade broad intersection is confirmed at the central part of the Oval area by OVD026. It includes a massive sulphide intercept in hole OVD026 of 1.8 metres of 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co from 105.0 metres within broader mineralisation of:
- 19.8 metres of 1.23% Cu, 0.98% Ni, 0.36g/t E3, and 0.05% Co from 91.2 metres.
OVD026 is located 100 metres northwest of the previously announced 8.8 metres of massive sulphide identified in drillhole OVD021.
On completion of the Phase 2 exploration work and receipt of all assays, Managing Director Gan-Ochir Zunduisuren, commented:“The 2024 Phase 1 and 2 drilling and exploration programs have confirmed the broad presence of high-grade mineralisation in the Oval gabbroic intrusion. The grades intercepted in some of the drillholes are exceptional and may be indicative of broader potential over a larger area, given Oval is a greenfields discovery.
The 2025 exploration program will focus on obtaining information on the size/metal content potential of the Oval Cu-Ni-PGE mineral system as well as targeting the possible deeper magmatic sources at Oval. Broader exploration is also planned at potential extensions of Oval and nearby look-a-like prospects. We look forward to updating shareholders on progress, with drilling expected to commence in around 8 weeks”.
Summary of Phase 2 exploration drilling at Oval Cu-Ni-PGE project
The Company’s recent drilling work has predominantly focused on finding high-grade mineralisation in the olivine-amphibole gabbro at the Oval project. The multiple intercepts of massive sulphide mineralisation with different ratios of metal contents throughout the Oval gabbroic intrusion is highly encouraging for the presence of one or more deeper sources of high grade mineralisation in the opinion of ABM.

Drillhole OVD02c
Drillhole OVD026 was designed to test the Down-Hole Electromagnetic (DHEM) conductor plate identified as OVD007_L2_B (reinterpretation of OVD007_L2_A2 by Southern Geoscience Consultants), which exhibits a conductance of 1,000 siemens. The drilling intersected a total of 1G.8 metres of mineralisation with 1.23% Cu, 0.G8% Ni, 0.36g/t E3, and 0.05% Co from G1.2 metres including;
- 4.8 metres of @ 0.45% Cu, 0.43% of Ni, 0.14g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 91.2 metres,
- 6.6 metres of @ 1.56% Cu, 0.G0% Ni, 0.50g/t E3, and 0.04% Co of net textured mineralisation from G6.0 metres,
- 2.4 metres of @ 1.52% Cu, 1.3G% Ni, 0.43g/t E3, and 0.07% Co of semi massive sulphide mineralisation from 102.6 metres,
- 1.8 metres of @ 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co of massive sulphide mineralisation from 105.0 metres, and
- 4.2 metres of @ 0.57% Cu, 0.45% of Ni, 0.21g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 106.9 metres (Table 1 provides a detailed breakdown of mineralisation intervals).
OVD026 is located in the Oval area, which is approximately 100 metres northwest of the previous intersection identified in drillhole OVD0213. This intercept may represent an extension of the known massive sulphide mineralisation in the Oval area and highlights the potential for further expansion of massive sulphide zones within the broader prospect area (Figures 1 and 3).
