Warriedar Resources Limited (ASX: WA8) (Warriedar or the Company) is pleased to release assay results from drilling undertaken at the Ricciardo deposit (previously known as Silverstone) within its Golden Range Project located in the Murchison region of Western Australia. The results released today have confirmed the presence of high-grade shoots below existing oxide open pits and demonstrates the excellent exploration potential for further discoveries at Ricciardo.
HIGHLIGHTS:
- Assay results received for thirteen (13) RC holes drilled at the Ricciardo deposit with all holes intersecting significant intervals of gold mineralisation, including:
- 32m @ 3.59 g/t Au from 148m, incl. 1m @ 10.85 g/t Au from 151m (RDRC019)
- 11m @ 3.43 g/t Au from 149m (RDRC031)
- 14m @ 1.15 g/t Au from 114m (RDRC022)
- 3m @ 5.61 g/t Au from 114m, incl. 1m @ 11.20 g/t Au from 114m (RDRC025)
- Drilling has identified two new high-grade shoots beneath the historical open pits at Silverstone and Silverstone South.
- Significant extensions of high-grade gold mineralisation have been intersected under the Ricciardo deposit at shallow depths (of between 150 - 200m) – which confirms the potential for further discoveries below historical open pits.
- Drilling demonstrates the excellent potential for significant growth of the Ricciardo deposit and Resource.
- Assays from a further nine (9) RC holes are pending with results anticipated to be received in the next four weeks.
- The Ricciardo deposit remains open along strike and at depth, with further growth-focussed drilling of this area planned from Q2 CY2024.
- Ricciardo sits in the middle of the 25km long Golden Corridor at Golden Range, which hosts six discrete deposits that are all open at depth and possess immediate growth potential.
- Ricciardo and the Golden Corridor to be the key focus of Warriedar’s exploration in 2024.
Warriedar Managing Director and CEO, Dr Amanda Buckingham, commented:
“We are very pleased with the results from this first batch of assays from the growth-focussed 2024 drilling program at Ricciardo. The results demonstrate the excellent potential to expand the Mineral Resource at Ricciardo, which has a strike length of 2.3km with high-grade gold mineralisation occurring at numerous locations along the trend.
With further assays pending, and follow-up drilling planned to commence from next quarter, we are excited as to what our exploration activities at Ricciardo can deliver for Warriedar this year.”

Robust high-grade extensions delivered across Ricciardo
21 holes have been drilled at Ricciardo during 2024 for 3,500m of drilling. This drilling was targeted to significantly extend the Ricciardo Mineral Resource boundaries at depth and along strike. The results released today have been able to achieve both goals.
Assay results have now been received for 13 holes drilled at Ricciardo. All 13 holes have returned significant gold intercepts, as reported in Table 2, with the better results provided below;
- 32m @ 3.59 g/t Au from 148m in RDRC019 beneath Ardmore pit.
- 11m @ 3.43 g/t Au from 149m in RDRC031 beneath Silverstone pit.
- 8m @ 1.84 g/t Au from 171m in RDRC032 beneath Silverstone pit.
- 14m @ 1.15 g/t Au from 114m in RDRC022 beneath Silverstone South pit.
- 10m @ 1.63 g/t Au from 156m in RDRC027 (ended within mineralisation) beneath Silverstone South pit.
The results have identified two additional high grade gold shoots within existing mineralisation as well as significant down-dip extension of the known mineralisation below the historic Silverstone and Silverstone South open pits. These results demonstrate the high-grade growth potential beneath Ricciardo both along strike and down dip of all five historic pits (Eastern Creek, Silverstone South, Silverstone (Copse), Ardmore, and Silverstone North) see Figure 3.
The Ricciardo deposit has a current Mineral Resource estimate of 8.7 Mt @ 1.7 g/t Au for 476 koz gold (6 koz Measured, 203 koz Indicated, 267 koz Inferred).1 The oxide material at Ricciardo (extending to 45 - 60m depth) has previously been mined across two separate phases: 2001 - 04 and 2013 - 19.
The Ricciardo gold system spans a strike length of approximately 2.3km, with very limited drilling having been undertaken below 100m depth.
The high-grade shoots comprising the Ricciardo mineralisation remain open both at depth and along strike. As a result of the strong growth potential (and its existing scale and grade), Ricciardo is a key focus area for Warriedar this year. Follow-up drilling at Ricciardo is planned from Q2 CY2024.

Continued Delivery of High Grade Antimony Mineralisation at Ricciardo
HIGHLIGHTS:
- Review of the antimony (Sb) potential at Ricciardo is complete with drillhole assay data confirming Sb mineralisation of significant thickness and grade exists below both the Ardmore pit (previously identified) and the Copse-Silverstone pits (newly identified), representing a potential combined strike length of approx. 1km.
- Multiple significant Sb intervals have been identified (reviewing both historic and WA8 drill hole assays), in addition to results recently released (* indicated below):
- Most of the Sb mineralisation appears to be located above the main gold zone, a distinct metallurgical positive for future processing and economic potential. Similarly to the gold mineralisation, the Sb zones remain wide open at depth.
- Only 11% of historical drill samples at Ricciardo were assayed for Sb. Retained pulp samples from historical holes are currently being tested with pXRF, with those favourable for significant Sb set to undergo laboratory multi element assay.
- An approx. 100kg high-grade sample of antimony mineralisation from Ricciardo has also been dispatched for scoping-level metallurgical testwork.
Warriedar Managing Director and CEO, Amanda Buckingham, commented:
“Following the recent high grade antimony intersections at Ricciardo, our initial review of the broader antimony potential has delivered further promise. An exceptionally high-grade antimony interval, as well as a much wider intersection, are now able to be placed in greater context. This context is a broader volume of antimony, not yet well-defined but with existing drilling showing serious scale and grade potential.
“Importantly, the high-grade antimony appears relatively discrete from higher-grade gold mineralisation, an excellent metallurgical outcome. While it remains early days, we are cautiously optimistic and have commenced initial metallurgical testing for potential processing and antimony recovery.
“While we are excited about this emerging opportunity at Ricciardo, I want to emphasise however that pursuit of this opportunity will be in parallel with our growth-focussed gold drilling at Golden Range, which remains our current core focus.”

Key Ricciardo context
The Ricciardo gold system spans a strike length of approximately 2.3km, with very limited drilling having been undertaken below 100m depth. Ricciardo possesses a current Mineral Resource Estimate (MRE) of 8.7 Mt @ 1.7 g/t Au for 476 koz gold.1
Historical gold mining operations at Ricciardo were primarily focused on the oxide material, with the transition and primary sulphides mineralisation not systematically explored. Antimony was not a focus of previous exploration, with only about 11% of historic drill holes assayed for antimony.
The gold and antimony mineralisation at Ricciardo is predominantly hosted within intensely altered and deformed ultramafic units. The high-grade antimony-dominant mineralisation occurred later than the main gold events and generally sits above the high-grade gold mineralisation.

Further Strong Extensional Diamond Drill Results from Ricciardo
HIGHLIGHTS:
- All residual assay results received from the recent 2,701m (27 holes) diamond drilling program at Ricciardo.
- Drilling underneath the Silverstone pit confirms the identified high-grade shoot continues at depth and at better than previously modelled grades:
- 13.7m @ 3.27 g/t Au and 0.36% Sb (4.04 g/t AuEq) from 253.3m, inc.
1.2m @ 9.00 g/t Au and 0.00% Sb (9.00 g/t AuEq) from 264.85m (RDRC046) - 22.6m @ 2.11 g/t Au and 0.29% Sb (2.71 g/t AuEq) from 294m, inc.
3m @ 7.22 g/t Au and 0.02 % Sb (7.26 g/t AuEq) from 312m (RDRC044)
- 13.7m @ 3.27 g/t Au and 0.36% Sb (4.04 g/t AuEq) from 253.3m, inc.
- Drilling from the Eastern Creek area, located at the southern end of Ricciardo, confirms down dip continuity with increasing grade and width at depth:
- 7.0m @ 2.54 g/t Au and 0.24% Sb (3.05 g/t AuEq) from 170m (RDRC060)
- 25.0m @ 1.23 g/t Au and 0.17% Sb (1.60 g/t AuEq) from 232m, inc.
6.8m @ 2.37 g/t Au and 0.37% Sb (3.16 g/t AuEq) from 250.2m (RDRC059)
- Update of Ricciardo Mineral Resource Estimate (MRE) on track for Q4 2024.
- Aircore drilling program now in progress at the Golden Range Project targeting an underexplored section at the southern end of the 70-km long shear.
- Further growth-focussed Reverse Circulation (RC) drilling of the ‘Golden Corridor’ scheduled to commence in November.
The assays reported in this release are full results for the final 11 diamond holes (1,021m) from the recent 27-hole diamond tail program at Ricciardo. Results for the first 16 holes of this program have previously been reported (refer WA8 ASX releases dated 3 July 2024, 19 July 2024, 2 August 2024 and 26 August 2024).
Warriedar Managing Director and CEO, Amanda Buckingham, commented:
“This final set of diamond results from the recent Ricciardo drilling have really put a bow on the whole program for us. The broad-based extensional success delivered by this drilling is both real and exciting. The fact that these results are being delivered at what are still relatively shallow down-dip depths, and in such proximity to excellent surrounding infrastructure, also delivers excellent potential for the economic character of the anticipated resource additions at Ricciardo. It is my firm belief that we are just getting started in terms of the opportunity at Ricciardo, let alone within the larger ‘Golden Corridor’ and along the broader mineralised shear.”
Key Ricciardo context
The Ricciardo gold system is located within Warriedar’s flagship Golden Range Project in the Murchison region of Western Australia (refer Figures 1 and 2).
Ricciardo spans a strike length of approximately 2.3km, with very limited drilling having been undertaken below 100m depth. It possesses a current MRE of 8.7 Mt @ 1.7 g/t Au for 476 koz gold. 1 Importantly, historical mining operations at Ricciardo were primarily focused on oxide material, with the transition and primary sulphides mineralisation not systematically explored.
Figure 1: The Golden Range and Fields Find Projects, with proximate mines, mills and projects.
Figure 2: The ‘Golden Corridor’ within the Golden Range Project. The image on the right is gravity over shaded residualmagnetic RTP.
The most recent phase of RC and diamond drilling of Ricciardo has concluded. This release reports on the assays from the final 11 holes of the diamond program. These holes were predominantly located in the southern part of the Ricciardo deposit, focusing on down-dip extension where no previous drilling had been undertaken (refer Table 1 and Figure 3 for drill collar and relevant section locations).
All 11 holes returned significant intersections, delivering a further round of meaningful extensional success from the recent program (refer Table 2). All results are set to be incorporated into an update of the Ricciardo MRE, which remains on track for completion during Q4 2024.

Further Step-Out Gold Success and High-Grade Antimony Discovery
HIGHLIGHTS:
- Assay results received for a further 1,102m of diamond drilling at Ricciardo.
- Extremely high-grade antimony (Sb) intersected in multiple holes below the Ardmore pit, including in RDRC067 above the main zone of high-grade gold mineralisation:
- 12.7m @ 4.98% Sb and 0.36 g/t Au (10.92 g/t AuEq*) from 229.2m
incl. 1.85m @ 28.50% Sb and 0.45 g/t Au (60.94 g/t AuEq) from 238.25m
- 12.7m @ 4.98% Sb and 0.36 g/t Au (10.92 g/t AuEq*) from 229.2m
- A wide zone of antimony mineralisation was encountered in hole RDRC001:
- 34m @ 1.0% Sb and 0.59 g/t Au (2.72 g/t AuEq) from 158.80m
- This newly identified and exceptionally high-grade Sb zone, along with the broader antimony potential at Ricciardo, demands prompt follow-up and evaluation.
- Further high-grade gold extension delivered below the Ardmore pit:
- 18m @ 3.41 g/t Au and 0.27% Sb (3.97 g/t AuEq) from 276m (RDRC048B) incl. 4.5m @ 9.90 g/t Au and 0.01% Sb (9.93 g/t AuEq) from 286.5m
- 1m @ 28.31 g/t Au and 2.18% Sb (32.92 g/t AuEq) from 286m (NMRC005)
- 42.6m @ 1.08 g/t Au and 0.05% Sb (1.17 g/t AuEq) from 253.38m (RDRC067)
- ‘Golden Corridor’ diamond drilling now complete, with 31 holes drilled for 3,300m.
- All residual diamond assays expected to be received by late September, with update of the Ricciardo Mineral Resource targeted for Q4 2024.
- Further growth-focussed RC drilling of the ‘Golden Corridor’ scheduled for H2 2024, as well as planned aircore drilling along select parts of the regional shear.
Warriedar Managing Director and CEO, Amanda Buckingham, commented:
“The results for these holes successfully demonstrate further extensional high-grade gold, and for the first time very high-grade antimony zones below the Ardmore pit area.
Given the relative absence of assaying for antimony in historical drilling at Golden Range, we are cautiously optimistic on the potential that might exist here. Moreover, the apparent zonation in RDRC067 is also highly encouraging for any future antimony development potential.
I want to emphasise however that pursuit of this opportunity will be in parallel with our growth-focussed gold drilling at Golden Range, which remains our current core focus.”

Key Ricciardo context
The Ricciardo gold system spans a strike length of approximately 2.3km, with very limited drilling having been undertaken below 100m depth. Ricciardo possesses a current MRE of 8.7 Mt @ 1.7 g/t Au for 476 koz gold.1 Historical mining operations at Ricciardo were primarily focused on oxide material, with the transition and primary sulphides mineralisation not systematically explored.
Due to the limited number of multi-element assays from historical drill holes at Ricciardo, other mineral potential (outside of gold) has also not been properly evaluated historically.
Figure 2: The ‘Golden Corridor’ within the Golden Range Project. The image on the right is gravity over shaded residual magnetic RTP.
The gold mineralisation at Ricciardo is predominantly hosted with intensified altered and deformed ultramafic units. It is important to note that the newly identified antimony-dominant mineralisation identified in RDRC067 (discussed below) sits above high-grade gold mineralisation in the same area, and may overprint the earlier gold mineralisation in some areas.
High-grade antimony zone discovery below the Ardmore pit
RDRC067 was designed to drill south to north along strike to better understand the structural controls within the Ricciardo deposit and assess the continuity of the ultramafic unit (Figure 3). All previous drill holes (by Warriedar and previous explorers) have been drilled eastward perpendicular to the known mineralised structure. RDRC067 was considered an important hole by the Warriedar technical team in order to confirm there are no additional structural controls and to provide further confidence in the geological model.
Figure 3: Plan view of Ricciardo deposit with current cross section locations annotated. The holes drilled in Q2/Q3 as part of the current program are highlighted in red. Additional holes are also outlined but not presented in below cross sections.
Unexpectedly, RDRC067 intersected significant high-grade antimony mineralisation from 229.2m to 241.9m downhole, returning 12.7m @ 4.98% Sb and 0.36 g/t Au (10.92 g/t AuEq) (Figure 4). Above this high-grade antimony zone, another significant zone was also identified from 183m to 198.1m downhole, returning 15.1m @ 1.42% Sb and 0.42 g/t Au (3.42 g/t AuEq) (Figure 4).
The antimony zones intersected by RDRC067 are interpreted to correlate with a lower grade antimony zone intersected in RDRC038 and RDRC049 (Figure 4). Encouragingly, drillhole RDRC001 returned a wide zone of antimony mineralisation: 34m @ 1.0% Sb and 0.59 g/t Au (2.72 g/t AuEq). Further work is required to determine the geometry and extent of the antimony mineralisation.
RDRC067 concluded at 296.96m downhole depth, within the gold mineralisation domain, as the target depth of the hole had been reached. As RDRC067 is not drilled perpendicular to the Mougooderra Shear, which is the main control of the mineralisation, it is important to note that the intersected thickness does not reflect the true thickness of the mineralisation.

Infill Drilling of Ricciardo Deposit Delivers Significant Gold Mineralisation
HIGHLIGHTS:
- Assay results for a further two (2) diamond tails at Ricciardo confirm a 77m wide (not true width) mineralisation zone 180m down-dip of the current Resource beneath the Ardmore pit, including a high-grade shoot.
- Significant gold intervals include:
- 7.2m @ 4.51 g/t Au from 232.8m, incl. 3m @ 9.03 g/t Au from 234m
- 10.5m @ 1.53 g/t Au from 218.8m
- 3.9m @ 3.35 g/t Au from 218.8m
- 23.2m @ 1.60 g/t Au from 270.8m
- Mineralisation in this area is structurally complex, extends to a vertical depth of ~ 460m and remains open.
- Ricciardo sits in the middle of the 25km-long ‘Golden Corridor’ at Golden Range, which hosts six (6) discrete deposits (18 historic pits) that are all open at depth and possess immediate growth potential.
- Current diamond drilling program (now extended to 3,000m) at Ricciardo and M1 set to be completed in mid-August, with all assays expected by late-September.
- Update of the Ricciardo MRE is targeted for Q4 2024.
- Further growth-focussed drilling of the ‘Golden Corridor’ scheduled for H2 2024.
The results reported in this release are for a further two (2) of the diamond holes drilled in the current program. Results for the first twelve (12) diamond holes of the current program were previously reported (refer WA8 ASX releases dated 3 July 2024 and 19 July 2024).
The results for these two (2) holes again demonstrate wide infill of the broader Ricciardo deposit at depth, further validating the outstanding Mineral Resource Estimate (MRE) growth potential that exists at Ricciardo and along the broader ‘Golden Corridor’ trend (refer Figure 2).
Warriedar Managing Director and CEO, Amanda Buckingham, commented:
“The outcomes of these two diamond tails are significant, given that they represented substantial depth step-outs under the shallow Ardmore pit. A 77m wide mineralised zone (downhole) with a central high-grade shoot (4.51 g/t), 180m below the MRE is a great result. We don’t fully understand the structural geometry here yet, but we are delighted that the deeper part of hole 49 validates the drill results from a previous explorer – confirming the deposit extends to about 460m vertical depth and retains some good grade (3.19 g/t). Excellent progress.
We continue to drill ahead at Ricciardo as part of the current diamond program, with follow-up growth drilling activities in planning for the remainder of H2 2024.”

- KR-272: 11.4m @ 13,383 ppm TREO1 from 102.7 (NdPrO2 3,982 ppm)
- The tables of REE Mineralised Zones >1,000 ppm TREO (in the announcement below) detail many more results worthy of attention
Prospech Managing Director, Jason Beckon, commented:
"Korsnäs keeps delivering standout results, with recent recognition of high grade zones rich in critical Heavy Rare Earth Elements (HREEs) like dysprosium (Dy) and terbium (Tb).
While Korsnäs is primarily a carbonatite-associated deposit known for valuable magnet REEs such as neodymium (Nd) and praseodymium (Pr), the presence of significant Dy and Tb mineralisation is a major advantage. These heavy REEs are crucial for producing high strength magnets which hold up under high temperatures and perform reliably in demanding applications like electric vehicles, wind turbines and high-efficiency motors.
With current supply disruptions in China, securing a stable source of these materials is more important than ever. Prospech is looking to meet this need, positioning itself as a dependable future supplier of magnet critical HREEs. Our commitment to thoroughly assessing these enriched zones at Korsnäs reflects our confidence in the project’s potential and our determination to support the growing global demand for sustainable energy technologies. By developing Korsnäs as a secure supply source, we are not just meeting immediate industry needs; we’re playing a key role in strengthening the resilience of global rare earth supply chains for the long term."
Initially developed as a lead mine, the Korsnäs project also hosts extensive rare earth element (REE) zones, which remain open both along strike and at depth. The site features a series of layered carbonatite zones, each up to 20 metres thick and separated by 50 to 100 metres along the strike. These REE enriched zones correlate with gravity anomalies, represented as orange ellipses on the included plan. So far, five such anomalies have been identified, extending over a strike length of more than 5 kilometres.
Focusing on REE mineralisation, the Company has conducted a comprehensive REE sampling program on the historic Korsnäs core stored by GTK at their data facility. Assay results have been reported in ASX announcements on 11 May 2023, 14 June 2023, 5 September 2023, 24 October 2023, 21 November 2023, 12 December 2023, 16 January 2024, 5 February 2024, 26 March 2024, 4 July 2024 and 4 November 2024.
Map showing the locations of drilling at Korsnäs. Newly reported holes are marked with red circles, previously reported holes with additional new assays are represented by blue triangles. Gravity-low anomalies are indicated by orange ellipses.
Presented below are two tables of assay intersections from the latest batch. The first table lists intersections from newly assayed holes that have not been reported before. The second table (in two parts) includes intersections from previously reported holes, now updated with additional assays from the margins of mineralised zones.

Ultra-High Grade Naturally Occurring Antimony at Alturas Project with Assays up to 69.98% Sb
Highlights
- Rock chip samples from the Alturas Antimony project in British Columbia, Canada, have returned outstanding ultra-high grade Antimony assays, including:
- 69.98% Sb – sample ALT24-PS-R003
- 67.96% Sb – sample ALT24-JL-R004
- 49.98% Sb – sample ALT24-JL-R005
- 47.97% Sb – sample ALT24-JL-R002
- 45.55% Sb – sample ALT24-JL-R003
- 44.45% Sb – sample ALT24-PS-R002
- 37.39% Sb – sample ALT24-PS-R004
- 28.81% Sb – sample ALT24-PS-R005
- 20.89% Sb – sample ALT24-JL-R009
- 20.17% Sb – sample ALT24-PS-R001
- 18.01% Sb – sample ALT24-JL-R007
- 16.77% Sb – sample ALT24-JL-R010
- 14.75% Sb – sample ALT24-JL-R001
- 12.42% Sb – sample ALT24-PS-R006
Pure Stibnite, Antimony Ore contains 71.4% Sb
- Additional ground totaling 3.3 km2 has been strategically staked to the east and west of the property, offering further potential to expand the mineralised footprint.
- 105 tonnes of Antimony ore, averaging 57.20% Sb has been historically sold from the Alps- Alturas Antimony Mine on this property.
- Since the execution of the option agreement for the Alturas project, the price for Antimony has reached US$36,000 per metric ton as of October 25, 2024, from approximately US$24,000 per metric ton at the time of acquisition. This significant price increase has been driven by supply constraints arising from new export controls on antimony announced by China in September 2024.
- Malachite stained rock chip from copper-bearing boulder field returned up to 0.96% Cu, offering potential for copper mineralisation beneath the surface.
- Drilling underway at Brazilian REE projects with assay results pending.
Equinox Resources Managing Director, Zac Komur commented:
We are thrilled to announce our latest exceptional exploration results, revealing extraordinary antimony assays that highlight the immense potential of the Alturas Project. Rock chip samples have returned grades as high as 69.98% antimony (Sb), establishing some of the world's highest reported natural stibnite (Sb2S3) grades. Considering that pure stibnite contains 71.4% antimony, these findings confirm Alturas as a truly unique and valuable asset.
By strategically expanding our footprint with additional claims to the east and west, we are positioned to explore beyond the known mineralisation. The discovered copper zone, with rock chips grading at 0.96% Cu, along with an extensive shear system, further solidifies Alturas as an outstanding opportunity. This project offers us a rare chance to unlock substantial value by systematically exploring an underexplored, ultra-high-grade asset in a mining-friendly jurisdiction.
We’re also continuing drilling at our Mata da Corda Titanium and Campo Grande Rare Earth Projects in Brazil, with assays pending.”
Reconnaissance Sampling
In September 2024, Equinox Resources conducted a maiden reconnaissance sampling campaign at the Alturas Antimony Project to evaluate the potential for high-grade antimony and associated polymetallic mineralisation along the extensive shear zone. The objectives of the reconnaissance campaign were to map and sample key structures by focusing on the 1.5 km shear zone, identified as the main mineralising structure, and to assess antimony concentrations in rock chip samples across newly identified dilation zones and extensions.
Figure 1: Location diagram of rock chip and soil samples taken with mapped shear zone identified
Figure 2: Assay results concentrated across the shear zone (Sb grades greater than 1%)
Project Overview
The Alturas Antimony Project is located in the Slocan Mining Division of British Columbia, Canada, approximately 15 kilometers northeast of New Denver. The project area is situated within a favorable geological setting, featuring a 1.5 km shear zone with polymetallic potential, including antimony, copper, and silver. The tenements cover the historic Alps-Alturas mine, an Antimony mine which operated between 1916 and 1926 selling ultra-high grade Antimony, averaging 57.2% Sb and up to 59.50% Sb. On 10 September 2024, Equinox Resources entered into a 12-month option to acquire 100% interest in all three tenements.

Woomera Completes Maiden Drilling Program at Bronze Fox Copper-Gold Porphyry Project
- Woomera’s first drill programme at the Bronze Fox Project in Mongolia has been completed.
- 16 Diamond drill holes were completed for a total of 2516m.
- Drilling largely focussed on shallow infill and extension drilling with a single deeper hole (F109/916.4m) testing a coincident geophysical/structural target.
- The target porphyry was intersected in all holes with assays due late December/early January.
- Woomera can earn an 80% interest in the Bronze Fox Project by spending US$4m on exploration (with an election to acquire 100%).
Assays for the program are expected to be available in late December 2024 or early January 2025. Woomera can earn an 80% interest in the Bronze Fox Project from Kincora Copper Limited (ASX: KCC) by expenditure of US$4m and has to the right to acquire a 100% interest.

BRONZE FOX PROJECT
The Bronze Fox Project covers 175km2 and is located in the Southern Gobi porphyry belt of southern Mongolia, approximately 450km south of the capital Ulaanbaatar. It represents an opportunity to secure a 100% interest in an underexplored world-class porphyry copper project with genuine Tier-1 potential. Drilling by Kincora totalling 46,625 metres of Reverse Circulation and Diamond Core drilling has defined three shallow, large porphyry complexes, providing genuine new discovery potential, resource delineation and early-stage exploration plays.
The Bronze Fox Project contains the West Kasulu Inferred Mineral Resource of 194.1Mt at 0.26% Copper Equivalent (CuEq), at a 0.2% CuEq cut-off to a depth of approximately 325m below surface and an Exploration Target of between 100Mt and 300Mt at 0.25 to 0.35% CuEq.20221
The Bronze Fox Project is located proximal to several world class mineral deposits including Oyu Tolgoi, Kharmagtai, Tsagaan Suvarga and Tavan Tolgoi (see Figure 3).

Kurundi Main Assay Results Tennant Creek
- TTRC098: 9m @ 1.62g/t Au from 49m including 1m @ 12.75g/t Au from 53m.
Other high-grade results include:
- TTRC103: 3m @ 8.3g/t Au from 35m including 1m @ 16.25/t Au from 36m at the central main zone.
- TTRC092: 5m @ 2.14g/t Au from 38m including 1m @ 6.39g/t Au from 40m at the central main zone.
- TTRC110: 2m @ 5.11g/t Au from 44m including 1m @ 6.33g/t Au from 45m at the northern workings
Also, a possible new style of mineralisation on a porphyry-basalt contact, footwall to the central main mineralized zone has been identified (requires further investigation - see Central Target Area section below) with an intersection of:
- TTRC103: 2m @ 10.93g/t Au from 51m including 1m @ 20.75g/t Au from 51m.
All intersections are stated as down hole widths which are close to true width for the Kurundi Main structure. A second phase of drilling has commenced to test the new southern high-grade zone and continue exploring the other Kurundi Main targets.
Figure 1: Kurundi Main Prospect 2024 drilling (blue dots) with best new results (yellow labels). 2022 drilling shown as black dots.
A total of 28 RC holes for 1,986m have been completed (results listed in Table 2) testing 3 main targets: (1) northern and southern extensions of the Kurundi structure up to 1km from the central main workings, (2) testing the plunge of the central high-grade shoot intersected in 2022 drilling, (3) testing mineralisation deeper under the central main workings.
Central Target Area:
Drilling has confirmed a southerly plunge to the central main high grade gold mineralisation identified in 2022 drilling with TTRC0103 and TTRC092 intersecting high grade gold mineralisation (Figure 2). Also, TTRC103 intersected an unexpected high grade gold zone of mineralisation footwall to the central main zone, on the contact between the basalt host rock and a porphyry intrusive unit (cross section in Figure 3). Due to the lack of structure and alteration being visible in the drill chips the result was initially perceived as a sampling error (2 composite samples from this interval returned anomalous results). However, re-assaying of the pulps followed by resampling at 1m intervals confirmed the presence of gold mineralization and eliminated possible sampling and laboratory errors. This possible new style of mineralisation will be investigated thoroughly with reinterpretation, drill hole relogging, multi element analysis, petrography and drilling to understand possible orientations, further targeting and to eliminate the possibility of down hole contamination of samples during the drilling of TTRC103.
In the Central Target Area KRR’s previous 2022 drilling only tested to a vertical depth of 40m. Four new holes have now been drilled to test a vertical depth of 65m. All holes intersected strong structure, alteration and veining confirming the continuation of the central target zone at depth. TTRC105 intersected a broad zone of veining and alteration and returned 10m @ 0.32g/t Au including 1m @ 0.98g/t Au from 68m with mineralisation open at depth and to the south, shown in the long projection below (Figure 2). The presence of strong veining and shearing at depth across the strike of the central zone is very encouraging for further, deeper drilling.

New results shown in yellow boxes, 2022 results shown in grey boxes, light purple box is for the footwall intersection.
TTRC112 was drilled to test a resistivity anomaly identified by 2023 DDIP survey (KRR ASX: 28 June 2024) however no cause for the resistivity anomaly was identified.

Exploration Program Commences at Virka
Key Highlights
- Historic data review identifies three areas for immediate field investigation
- Initial mapping and reconnaissance sampling underway
- Historic drill core located for relogging, and where possible, sampling:
- Evidence for both significant width and grade mineralisation at the Virka project from drilling which included 1,2
- 9 m at 1,087 ppm U3O8 from 24.5 m in drill hole 81-003
- within 17 m at 707ppm U3O8 from 23 metres depth
- Evidence for both significant width and grade mineralisation at the Virka project from drilling which included 1,2
- No modern systematic exploration undertaken with last significant exploration in 1980’s highlighting district scale potential
Initial work will focus on the assessment of three areas identified through reviewing historic reports. Limited exploration work was documented, but recorded anomalous base metals, silver and uranium. Exploration work at Virka focussed on North-NorthEast orientated structural features, which were interpreted to be a suitable structural conduit for potential mineralisation.
Basin’s Managing Director, Pete Moorhouse, commented:
“The team at Basin are extremely excited to commence work on the recently announced Scandinavian uranium and green energy metals portfolio. Initial review of the available historical data on the Virka project has provided areas for immediate groundwork. We know that the system is prospective for a variety of metals, with the historical drilling indicating favourable thickness of uranium mineralisation.
The team has commenced work immediately at Virka, conscious of the upcoming winter season. Initial work will focus on getting boots on the ground to assess rock outcrops and trace boulder trains. We will move to historic drill core review and additional literature compilation once the weather prohibits further ground activities.”
Virka Project Background 3
The Virka project is strategically positioned in the heart of the Arjeplog-Arvidsjaur shear-hosted uranium district in Sweden, and approximately 37 km southeast of Boliden’s (STO:BOL) Laisvall Pb-Zn-Ag former mine.
Figure 1: Virka initial work locations
Previous drilling activities conducted in the 1980’s across all licenses targeted uranium mineralisation, with diamond drillholes gamma probed and in rare occasions sampled for geochemical analysis3. Additionally, historical regional geological mapping and boulder tracing records unveiled several surface anomalisms in lead, zinc, silver and gold associated with fault structures. Research indicates that these anomalies have not been adequately followed up with results not verified to JORC Code (2012), however using this data and Basin’s interpretations, three areas have been prioritised for immediate field reconnaissance (Figure 1). This program has commenced with the review of these anomalous features that were historically reported in the project area.
