Drill Program at Yalgoo Confirms Continuity of LCT Pegmatites at Johnson Well
Firetail Resources Limited ("Firetail" or "the Company") (ASX: FTL) is pleased to provide an update on exploration activites at its Yalgoo Lithium Project ("Yalgoo") in Western Australia. Final assay results have been received from the Company’s drilling program at the Johnson Well Prospect, completed in late June.
Highlights include:
- Reverse Circulation (“RC”) Drilling program comprising 22 holes for 589m completed at the Johnson Well Prospect, following up from encouraging rock chip sample results.
- Pegmatites intersected in 3 of the 4 drill sections over a strike length of around 150m and appear continuous for ~ 120m down-dip.
- Encouraging assay results include 3m @ 0.83% LiO2 from 32m including 1m @ 1.16% LiO2 from 34m in JWRC-0005.
- Apparent increase in lithium grade down-dip in eastern-most drill section (Fence 1), where the deepest intersection of pegmatite returned the best assay results (JWRC-0005).
- All pegmatites intersected are open down-dip, with the next stage of RC drilling proposed to step- out further to the northeast and test these pegmatites at depth.

Executive Chairman, Brett Grosvenor, commented:
"We are really pleased to be able to report the results of this drilling at Johnson Well, that were received late last week. These results reflect an increased understanding of the region and further assurance that our team’s interpretation of the pegmatite system within the Yalgoo tenure is heading in the right direction
“Johnson Well is our second target drilled at Yalgoo to date and the confirmation of the LCT mineralisation gives us confidence that we are on the right track.
“Our Geological team, led by Robin Wilson, is hard at work planning the next round of activities to better understand the geology and potential for further LCT pegmatites in the region, as well as target generation for future drilling campaigns.”
Yalgoo Project – Johnson Well Prospect
RC Drilling
An RC drilling program was completed at the Yalgoo Project, Johnson Well Prospect in June 2023, following up from geological mapping and rock chip sampling1. The drilling program comprised of 22 holes for 589m with drilling completed on four traverses approximately 80m apart and drill holes 20m or 40m apart (see Figure 3 below).
Three of the four drill traverses intersected pegmatites indicating continuity over a strike length of at least 150m and also open down-dip. The pegmatites are interpreted to be relatively shallow-dipping towards the north/northeast and striking roughly west-northwest (see Figures 2 and 3 below).
Assay results have now been received which confirm the pegmatites intersected are Lithium-Caesium- Tantalum (LCT) pegmatites, with a best result of 3m @ 0.83% LiO2 from 32m in JWRC-0005 including 1m @ 1.16% LiO2 from 34m. All significant LiO2 assay results (>0.2% LiO2) are highlighted in the Table 2 below (Appendix 1). Lithium minerals observed in the pegmatites were predominantly lepidolite and zinnwaldite, associated with potassium feldspar, albite, muscovite and biotite.
Of note is the apparent increase in lithium grade at depth which is evident on Drill Fence 1 (see Figure 2 below) where the deepest pegmatite intersection returned the best lithium assay result (drill hole JWRC-0005).

Termination of Fifield Project Earn-in Agreement and Funding Update
Rimfire Pacific Mining Limited (Rimfire or the Company) (ASX: RIM) provides the following updates in respect of the Fifield Project, the Avondale Project, funding arrangements and next steps.
Termination of Fifield Project Earn-in Agreement
Rimfire has two projects in the Lachlan Fold Belt of NSW, each of which are prospective for critical minerals – the Fifield Project and the Avondale Project. Activities at both projects have been funded by Golden Plains Resources Pty Ltd (GPR) under separate earn-in arrangements, which have the potential to see GPR earn a joint venture interest of up to 50.1% (in the case of the Fifield Project) and up to 75% (in the case of the Avondale Project).
Rimfire has issued a notice of termination to GPR in respect of the Fifield Project Earn-in Agreement, with the termination stated to take immediate effect.
The Company has exercised a termination right which has arisen as a result of a change of control of GPR following the judgement of the Victorian Supreme Court in: Resource Capital Ltd v Giovinazzo [2024] VSC 548 (Judgement), delivered 6 September 2024.
Given the Fifield Project Earn-in Agreement was terminated prior to GPR satisfying the earn-in requirements, GPR will have no interest in the Fifield Project going forward. The express terms of the Fifield Project Earn-in Agreement do not require the Company to repay to GPR any funding provided by it prior to termination in these circumstances.
The Fifield Project contains the Murga North Scandium Prospect where Rimfire has recently reported an Inferred Mineral Resource estimate of 21Mt @ 125 ppm Sc (4,050t Sc Oxide) as well as an Exploration Target of 100 to 200Mt at 100 to 200ppm Sc* (15 – 46Kt Sc Oxide) for the surrounding Murga area (See Rimfire ASX Announcement dated 9 September 2024)**.
Rimfire is considering its rights in relation to the Avondale Project Earn-in Agreement in light of the Judgement and is currently seeking further information from GPR.
The Avondale Project contains the Melrose Scandium Prospect where Rimfire has recently reported an Indicated and Inferred Mineral Resource estimate of 3Mt @ 240 ppm Sc (1,120t Sc Oxide) (See Rimfire ASX Announcement dated 9 September 2024)**.

Maximus Hits 19m @ 3.21 g/t Gold at Hilditch as Development Activities Advance
Maximus Resources Limited (‘Maximus’ or the ‘Company’, ASX:MXR) is pleased to update shareholders on assay results received from a completed Reverse Circulation (RC) drill program at the Hilditch gold deposit (Hilditch) (90Å Maximus, 10Å Bullabulling Pty Ltd) located on a granted mining tenement 25km from Kambalda, Western Australia
- Assay results from a Reverse Circulation (RC) drill program at the Hilditch gold deposit return multiple shallow high-grade intersections, including:
- 19m @ 3.21g/t Au from 16m incl. 6m @ 5.64g/t Au from 18m and 5m @ 3.28g/t Au from 30m (HGRC065)
- 9m @ 3.11g/t Au from 63m incl. 4m @ 4.84g/t Au from 63m (HGRC068)
- 15m @ 1.12g/t Au from 24m incl. 1m @ 2.85g/t Au from 25m and 4m @ 2.12g/t Au from 35m (HGRC067)
- 5m @ 1.61g/t Au from 48m incl. 1m @ 2.02g/t Au from 48m and 1m @ 2.0g/t Au from 51m (HGRC065)
- Representative minable ore-grade intervals have been submitted for metallurgical test work under real-world toll milling protocols with results expected to be received in October. Initial results up to 95.8Å recovery of gold.
- Updated Mineral Resource Estimate (MRE) for Hilditch gold deposit targeted for October 2024.
- Development studies including geotechnical, environmental, infrastructure, surface water and hydrogeology assessments necessary for the mine approval process are advancing.
- The Hilditch gold project is situated on granted mining tenements, with excellent access to infrastructure, service providers and several toll-treating options within a 60km haulage.
- The Company is in active discussions with potential mining and toll-milling partners.
Eleven RC holes (722m) were drilled at Hilditch to investigate recent intersected high-grade zones. The Company has commenced updating the Hilditch Mineral Resource Estimate (MRE) to finalise optimised open-pit designs, aiming to secure mine approvals and advance discussions with potential mining and toll milling partners.
Maximus’ Managing Director, Tim Wither, commented, “The recent drilling results, including 19m @ 3.21g/t Au from 16m, fall within optimised open pit shells and support the MRE update prior to completing open pit designs. Hilditch offers a promising near-term gold production prospect for Maximus, situated on an approved mining tenement near the Coolgardie-Norseman highway, and within close proximity to multiple regional gold processing facilities.
“These new drilling results successfully expand the high-grade mineralised zones, and significantly improve the economic outlook for Hilditch, with efforts concentrated on advancing open pit development to generate cash flow for the Company, capitalising on the rising gold price environment.”
Hilditch Gold Deposit
Hilditch is located on a granted mining tenement adjacent to the Coolgardie-Norseman highway and is proximal to several toll-treating processing plants. The existing 19,500 oz Au @ 1.3 g/t Au mineral resource is shallow, with mineralisation commencing at the surface over a 200m strike length and remains open at depth with significant strike extension to be tested (ASX announcement 19 December 2023). The completed RC drill program was aimed at infill and resource extension to upgrade material classification into the indicated category, before updating the Hilditch MRE.
Gold mineralisation at Hilditch is interpreted to be associated with east-dipping structurally controlled contacts between mafic/ultramafic and volcaniclastic units. Minor interflow sediments are observed within the mafic and ultramafic sequence, similar to that prevalent at the Company’s Wattle Dam Gold Project. In the Hilditch region, the rocks show extensive weathering, reaching an average depth of 20 metres below the surface, indicative of full oxidation. From 20 to 40 metres, there exists a transitional zone, and beyond 40 metres, the rock is unweathered and contains primary mineralisation.
Preliminary metallurgical test work indicative of the Hilditch open-pit gold resource is free milling (non-refractory) with exceptional gold recoveries between 91.4Å and 95.8Å, indicating that the mineable ore is very amenable to conventional Carbon in Leach (CIL) gold processing found throughout Western Australia’s Eastern Goldfields. Completed metallurgical tests covered various gold grades and oxidation stages, ensuring representative sampling across expected mining depths (ASX announcement 3 July 2024). Further tests are underway to represent real- world toll milling protocols (Figure 2).
Figure 1 – Hilditch gold deposit significant drill results from recent drilling (gram x metres).
Drilling Results
The latest round of drilling expanded upon previous high-grade intersections near hole HGRC038, which had reported 4m @ 12.44g/t Au from 47m, including 1m @ 25.93g/t Au from 47m (Figure 1) (ASX announcement 15 August 2024).
Five RC holes were drilled in proximity to HGRC038. Notably, hole HGRC065, located 25m north of HGRC038, intersected 19m @ 3.21g/t Au from 16m, including 6m @ 5.64g/t Au from 18m and 5m @ 3.28g/t Au from 30m, effectively extending the high-grade zone to the north.
Additionally, hole HGRC068, situated 15m down-dip of HGRC038, intercepted 9m @ 3.11g/t Au from 63m, including 4m @ 4.84g/t Au from 63m. HGRC067 drilled 15m up-dip of HGRC038 returned 15m @ 1.12g/t Au from 24m, with notable intervals of 1m @ 2.85g/t Au from 25m and 4m @ 2.12g/t Au from 35m (Figure 3). These results confirm a well-defined, high-grade gold zone within the central part of the deposit, bolstering geological confidence and continuity of high-grade mineralisation.
At the northern limit of the deposit, several drill holes were positioned to the north of previously reported hole HGRC019, which intersected 7m @ 7.9 g/t Au from 51m, including 2m @ 16.9 g/t Au from 52m (ASX announcement 14 June 2022), in an effort to extend the resource along strike. However, drill holes HGRC059 to HGRC061 failed to return significant results, confirming that the mineralisation is closed off along strike to the north.

190 Metre Antimony Copper Intercept at Bulla Park
West Cobar Metals Limited (“West Cobar”, ASX:WC1) is pleased to advise that assays from the latest drilling of its 100%-owned Bulla Park Copper - Antimony Project (Figure 1), located 110km west of Cobar in New South Wales have shown drill intersections of broad and consistent copper and antimony mineralisation.
Highlights
- Recent diamond drilling confirms a thick zone of antimony copper mineralisation at Bulla Park with structural control from a major WSW trending fault
- Provides further confidence of a large antimony copper system at Bulla Park supporting previous drilling results - 33m at 0.47% Cu and 0.15% Sb (19CA002, 229m to 262m)1
- BPD09 encountered copper - antimony grades up to 1m at 1.04% Cu, 0.55% Sb (204m to 205m)
- Broad intercepts from BPD09 include 190m at 0.23% Cu and 0.08% Sb from 128m
- Selected intersections from BPD09 include 66m at 0.34% Cu and 0.13% Sb, 7g/t Ag from 200m. Also:
- 4m at 0.44% Cu, 0.20% Sb and 7g/t Ag from 131m
- 10m at 0.47% Cu, 0.23% Sb and 9g/t Ag from 200m
- 4m at 0.53% Cu, 0.21% Sb and 10g/t Ag from 223m
- 13m at 0.45% Cu, 0.17% Sb and 7g/t Ag from 239m
- Gravity and aeromagnetic surveys indicate there is potential mineralisation along at least 1.8km of strike, over 350m of horizontal width and drill intersected thicknesses of approximately 60m
- Strong macroeconomic factors for antimony (prices are approx. US$22,700/t) and copper (prices are approx. US$9,300/t)*
- Antimony is on the critical mineral lists of both Australia and the US
- In addition, potential for stratiform massive sulphide silver – zinc - lead mineralisation exists south of the copper - antimony mineralisation
- Additional drilling planned to enable maiden antimony copper mineral resource estimate
West Cobar Metals’ Managing Director, Matt Szwedzicki, commented: “The Bulla Park project is shaping up to have potential for a major copper – antimony – silver deposit. The antimony content is exceptional and with the global prices of antimony trading at nearly 2.5 times the price of copper, it is a good time to have drilled through a major intercept of antimony mineralisation.
We are now planning the next drill program to follow the deposit along strike.”
Figure 1 - West Cobar’s Bulla Park Project exploration licences, interpreted geology and outline limits of aeromagnetic surveys flown.
Mineralisation is dominantly tetrahedrite (copper - antimony sulphide) and minor chalcopyrite and stibnite (antimony sulphide). Antimony grades in all drill hole intercepts are approximately 30% to 35% of the copper grade, reflecting the theoretical composition of tetrahedrite (Cu12Sb4S13).
The mineralisation has developed over several stages. Syn-depositional siderite alteration of Lower Devonian (Winduck Group) silty fossiliferous sandstones is accompanied by chalcopyrite and tetrahedrite. Synsedimentary microfaults and dewatering structures are common indicating a tectonically active depositional and mineralising environment. When subsequently lithified, brittle faulting and fracturing has resulted in siderite-barite stockwork veining and hydrothermal breccias with tetrahedrite as the main copper-antimony mineral. Later faulting is associated with tectonic breccias, massive siderite-barite veins up to 20m thick and tetrahedrite and stibnite crystals filling vughs and veins (Figures 2 and 3).

Gold Potential Builds at Black Swan
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.
