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.

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.
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.

- 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.

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.
