Warriedar Resources Limited (ASX: WA8) (Warriedar or the Company) is pleased to report on an updated MRE for its flagship Ricciardo Gold Deposit, part of the broader Golden Range Project located in the Murchison region of Western Australia.
HIGHLIGHTS:
- Updated Mineral Resource Estimate (MRE) for the Ricciardo Deposit (part of the broader Golden Range Project) of 16.44 Mt @ 1.8 g/t Au for 947.5 koz gold.
- Represents a 99% increase in Ricciardo MRE contained gold ounces.
- Proven high-returning exploration with the increased Ricciardo MRE ounces delivered at an attractive all-in discovery cost of only approx. A$16/oz.
- High-quality resource additions given drilling focus on high-grade growth ounces with strong commercial potential.
- The updated Ricciardo MRE comprises:
- 467.5 koz @ 1.6 g/t Au open-pit gold Resource (75% M&I) (optimised pit shell constrained at A$3,300/oz)
- 480.0 koz @ 2.0 g/t Au underground gold Resource
- Critically, the Ricciardo system remains wide open at depth and along strike.
- Total Golden Range Project Mineral Resources now stand at over 1.28 Moz gold, a 58% increase from the previous level.
- This initial outcome validates the excellent potential for further growth within the broader 25km ‘Golden Corridor’ via the ongoing, simple strategy of targeting fresh rock extensions under shallow existing pits.
- RC drilling at the southern end of the ‘Golden Corridor’ targeting high-grade Resource growth is progressing well; 9 holes completed for 1,472 metres to date, assays pending.
Warriedar Managing Director and CEO, Amanda Buckingham, commented:
“This is the result we have been working towards all year. With less than 15,000m of targeted, efficient drilling we have added over 470 koz to the Ricciardo deposit, doubling the Resource.
We are excited by both the outcome itself, and the outlook that it delivers us for the wider corridor of gold deposits. The simple strategy of drilling below shallow open pits to find mineable ounces worked exceptionally well for our producing neighbours. The validity of this strategy is now beyond doubt, for us.
Not only is the Ricciardo system still wide open down-plunge, but the entire 25km long ‘Golden Corridor’ offers similar potential upside from such a relatively simple drilling focus.
In the middle of the infrastructure-rich southern Murchison, and located on existing Mining Leases, the opportunity in front of us is utterly irresistible.”
The Ricciardo Deposit
The Ricciardo Gold Deposit is located on existing mining leases 100% owned by WA8, in the Murchison Region, approximately 300 km east of Geraldton, and 420 km by road north-northeast of Perth. Sitting approximately 8km South of the Golden Range Mill on M59/421, and M59/458, within the Golden Range group of historic open pit mines and deposits.
Discovered in the 1990’s, open pit mining of the oxide resources commenced in 2001, and the plant entered Care & Maintenance twice (between July 2004 and 2009, and May 2010 to mid- 2013). Production was over 300 Koz before finally going into ongoing Care and Maintenance in August 2019.
The Ricciardo deposit is located 90km north of Capricorn Metals’ Mt Gibson Gold Project, 8kms south of the Company’s plant, 26km from the neighbouring Golden Grove processing facility and 40 km northeast of Vault Minerals’ high grade Rothsay gold mine (Figure 1).
Figure 1: The location of the Ricciardo gold deposit within the Golden Range Project; within the broader Southern Murchison region.
The Ricciardo gold system spans a strike length of approximately 2.3km, with very limited drilling having been undertaken below 100m depth prior to Warriedar drilling. Historical mining operations at Ricciardo were primarily focused on oxide material, with the transition and primary sulphides mineralisation not systematically explored.
Warriedar’s drilling of Ricciardo during CY2024 achieved excellent results, demonstrating high- grade extensions to the resource. The results demonstrated that the previously quantified resource is part of a much larger system.
Warriedar engaged independent mining consultants, Measured Group to update the Ricciardo MRE, previously reported 476Koz gold.1
The Ricciardo Gold Deposit consists of six semi-continuous historical open pit mines along the 2.3 km arcuate stretch of the Mougooderra Shear Zone, running north to south. These mines are named (from north to south) Silverstone North, Ardmore, Copse, Silverstone, Silverstone South, and Eastern Creek (Figure 2).

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.”
Figure 1: The Golden Range and Fields Find Projects, with proximate mines, mills and projects.
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.”

Drilling Preparations at Abercromby Gold Project
BMG Resources Limited (ASX: BMG) (BMG or the Company) is pleased to announce that preparations to resume drilling at its 100%-owned Abercromby Gold Project are well advanced with the start of drilling scheduled for this month.
- Diamond drill programme focused on resource growth is scheduled to commence this month at the Abercromby Gold Project
- Extensional drilling of high-grade zones is planned with potential to add significantly to BMG's maiden resource of 518,000 oz Au at 1.45 g/t Au
- Infill drilling planned to convert inferred resources to the indicated category to support development studies
- Programme of Work approval in place
- Programme of Work approval in place
John Prineas, BMG's Non-Executive Chairman, said:
"Following the support shown by investors in the recent capital raising, the team at BMG have moved quickly to finalise arrangements to resume drilling at the Abercromby Gold Project.
"The drill programme will focus on expanding high-grade gold zones beyond the existing resource shell, as well as increasing resource confidence by upgrading inferred resources to indicated status.
"The results of the drilling have potential to contribute significantly to resource growth at Abercromby, and to ..iaterially boost the potential project economics."
Drilling for growth in gold resources:
BMG delivered the large maiden Mineral Resource at Abercromby after completion of only three drill campaigns and at a discovery cost of just $8.35 per ounce. This achievement highlights the extensive gold endowment at Abercromby, as well as the efficient exploration planning by our technical team.
This excellent track record of results at Abercromby provides confidence in the potential for continued drilling success at Abercromby that could increase the size of the gold resource.
The Abercromby Gold Project is owned 100% by BMG and comprised within two granted Mining Leases. The Project is located in an established mining region with access to infrastructure (roads, power) and proximal to a number pf producing gold mines.
The favourable metallurgical properties of the Abercromby ore were confirmed by metallurgical testwork completed by Extreme Metallurgy and reviewed by GR Engineering Services. That testwork concluded that the Abercromby gold mineralisation was free milling in nature and amenable to traditional carbon-in-leach processing. High gold recoveries were achieved in the range 93% to 95%.
Maiden Resource is just the beginning:
The maiden MRE for Abercromby is comprised in the Capital Deposit and is defined as 11.12Mt @ 1.45 g/t Au for 518,000 oz Au. This resource is a subset of a global resource estimate containing about 670,000 oz Au at a Og/t Au lower cut-off.
The Capital Deposit remains open at depth and along strike — both to the north and south. A diamond drilling program is planned to commence this month to test for extensions of the mineralisation as well as to convert inferred resources to the indicated category.
The prospective stratigraphy at Abercromby extends for more than 6km with only a strike of 1.2km systematically drilled to date. This provides potential for substantial discovery opportunities with further exploration drilling.
Drilling is also planned for early next year to test regional targets to the south of the Capital Deposit.
Reconnaissance aircore drilling at the Capital South, Archer and Barrack Prospects — located along a 1km corridor of prospective stratigraphy to the south of the Capital Deposit — has confirmed the presence of a large high-grade gold system and supports the potential for a repetition of significant mineralisation like the Capital Deposit.
Table 1: JORC-compliant Mineral Resource for Abercromby.
A further announcement will be issued by BMG once drilling commences at Abercromby.
For further information on the Abercromby resource, see our ASX announcement dated 6 February 2023 'High Gold Recoveries — Abercromby Met Testwork' and 17 April 2023 '518,000oz Au Maiden Mineral Resource for Abercromby Gold Project'.

Octava Secures Drilling Contractor for the High-Grade Antimony Project at Yallalong
Highlights
- Octava has now completed the selection process for a drilling contractor to conduct exploration at its 100% owned high-grade Yallalong antimony project in the Midwest of Western Australia.
- A 3000m drilling program is expected to commence by the end of this month and will focus on the Discovery target, where previous high-grade intercepts have been recorded including:
- YRC16: 7m @ 3.27% Sb from 12m including 1m @ 11.5% from 18m
- YRC06: 3m @ 6.83% Sb from 21m including 1m @ 13.6% Sb from 22m
- Maiden drill holes will also be completed on the Central antimony target, where no previous drilling has been done.
- Detailed geophysical survey over the identified antimony corridor at Yallalong is progressing well, now 40% complete.
- The geophysical survey will assist in defining additional antimony targets within the corridor, that may be transported cover.
Octava’s Managing Director Bevan Wakelam stated, "We are really pleased to have secured our drillers to undertake the exploration drill program to outline further high-grade antimony at Yallalong. We will target lateral extensions of existing, known high grade antimony mineralisation and also the underlying bedrock contacts. We also look forward to completing the geophysical survey that will provide us with better geological understanding of what’s below the surface along the antimony corridor.”
Figure 1. Cross-section through the Discovery antimony target showing mineralisation occurring parallel to the sedimentary and mafic rock contact and in the fault zone. (refer ASX announcement 17 September 2024)The antimony (Sb) mineralisation identified at Yallalong appears to occur within a 10km north-south striking mineralised corridor that is interpreted to be related to a structural corridor between the Darling and Woodrarung faults. The fault zones act as conduits for mineralising fluids into the sedimentary rocks that are peripheral to mafic intrusive dykes, a well-known geological setting for antimony deposits worldwide.
Octava is planning to drill two of the priority antimony targets at the Yallalong antimony Project, Discovery and Central. Previous exploration identified four principal antimony targets where antimony mineralisation was exposed at surface at all target locations. Only the Discovery Prospect has any drilling and remains open. Antimony ingot prices at that time were ~$8000/tonne compared to over $30,000/tonne now1. Drilling is expected to commence at the end of this month.
The detailed geophysical surveys are progressing well, now at 40% and on track to be completed in the next 7-10 days. The survey will provide clearer understanding on these key structures, such as shears & faults and provide better definition of controlling lithological boundaries.

Heavy REEs Terbium and Dysprosium from Korsnäs
- Further impressive assay results received from 307 samples, 25 historical drill holes
- Assays include heavy REEs (Terbium (Tb) and Dysprosium (Dy)) results up to 86 ppm and 313.4 ppm respectively
- Numerous high grade and broad REE intersections are reported, such as:
- KR-272: 11.4m @ 13,383 ppm TREO1 from 102.7 (NdPrO2 3,982 ppm)
Including4.0m @ 32,831 ppm TREO from 106.7m
(40.9 ppm Tb4O7; 227.4 ppm Dy2O3; 9,943 ppm NdPrO) - SO-187: 17.4m @ 9,798 ppm TREO from 0.0m (NdPrO 3,087 ppm)
Including3.0m @ 48,465 ppm TREO from 11.4m
(86.0 ppm Tb4O7; 313.4 ppm Dy2O3; 15,557 ppm NdPrO)
- 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.

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.

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.
