Warriedar Resources Limited (ASX: WA8) (Warriedar or the Company) is pleased to report on assay results received for a further five (5) drill holes from the Rothschild deposit, part of the ongoing Reverse Circulation (RC) drilling program at its Fields Find Project in the Murchison province of Western Australia (refer Figure 1).
HIGHLIGHTS:
- Second set of assay results comprising a further five (5) drill holes at the Rothschild deposit within the Fields Find Project.
- High-grade extensional intercepts returned including 5m @ 4.36 g/t Au from 91m, 12m @ 1.61g/t Au from 179m, and 12m @ 1.29 g/t from 228m.
- Further demonstration of substantial, multi-lode growth potential at Rothschild, both along strike and at depth; with mineralization extended to 220m below surface.
- Initial drilling program at Rothschild of 47 RC holes for 7,529m is now complete; assays for 38 holes are pending and expected to be received during the second half of June.
- Excellent results to date at Rothschild have encouraged acceleration of scout-drilling targeting ‘Rothschild analogues’, with similar or better geophysical responses, within the camp-scale setting of the ML that overlays that part of the Fields Find Project.
- Drilling of these high-potential targets is expected to commence during Q3 CY2023.
These results further demonstrate deposit extension at depth and, together with the initial assays released (see WA8 ASX announcement dated 28 April 2023), confirm Warriedar’s interpretation that the Rothschild deposit is much larger than currently defined in terms of both strike and depth extent.
Key intervals returned include (refer Table 1, and Figures 1, 4 and 5):
- 5m @ 4.36 g/t Au from 91m (BRRC088), ending in mineralisation;
- 12m @ 1.61g/t Au from 179m (BRRC089); and
- 12m @ 1.29 g/t Au from 228m (BRRC090), ending in mineralisation with assays from the last 32m pending.
The Rothschild deposit is one of several prospects within a larger camp-scale gold play, on the eastern side of the Fields Find Project (refer Figure 2). Ongoing success at Rothschild has encouraged the Company to bring forward scout-drilling of geophysically-targeted ‘Rothschild analogues’ within the wider existing Mining Lease (ML) that overlays that part of Fields Find.
Further assay results from Rothschild extensional drilling
The initial drilling program at Rothschild, which is now complete, was 47 RC holes for 7,529m. Results have now been received and released for 9 holes (the first 4 holes in WA8 ASX release dated 28 April 2023, and a further 5 holes in this release).

[RIGHT]: DEPOSIT SCALE – plan view of the existing resource and the locations of the holes drilled this year and historically. Gold assay results coloured by gram-m value (for historic significant intervals, see ASX Announcement 28 November 2022). The resource exhibits good continuity along strike. Drilling by the company has increased the depth extent of the deposit. The magnetic data would suggest the unit hosting the gold extends west of the fault. Drillholes BRRC118-120 were designed to test this hypothesis. BRRC118 intersected strong sulphides. See photo of the chip tray BOTTOM LEFT, chips for 74 to 79m downhole shown. Assays pending will inform the scale potential of the deposit. Underlying image = semi-transparent residual RTP magnetic data (using the 50m spaced survey over the prospect, 1999, survey 60712).
Two of the holes announced in this release failed to reach target depth due to excess water (drillholes BRRC086 and BRRC087). The remaining three holes intersected the target zone and extended the known depth of gold mineralisation (BBRC088, BBRC089 and BBRC090; refer Table 1 for full results).
Figure 3 shows the coverage of the 2023 drilling program completed to date at Rothschild. The location of the five holes with assays released in this announcement are highlighted in yellow (target depth achieved) and purple (target depth not achieved). Cross sections are shown in Figures 4 and 5.
The mineralization intersected in drillhole BRRC090 is 220m below surface (vertical depth), refer to Figure 5. The final 1m sample in the hole returned 3.12 g/t (240m downhole) with assays for the final 32m of the hole still pending. This 12m interval at > 1 g/t Au at 230m below surface, more than doubles the previously understood depth extent of the mineralization.

Warriedar Resources
Overview
Warriedar Resources (ASX:WA8) is an advanced gold and copper exploration company backed by a highly skilled team of experts, Warriedar maintains an incredibly strong and stable portfolio of gold assets in both Western Australia and Nevada. Between its three projects – Golden Range, Fields Find and Big Springs – it currently holds more than 2 million ounces of high-grade gold resources with blue-sky potential for growth, and a robust pipeline of high-quality drill targets. Warriedar is well-funded for its planned 2024 drill programs focused on rapidly building its gold resources.
Two of its brownfield projects – Golden Range and Fields Find – are located in Western Australia's Murchison Province, widely known as an active mining and exploration region. Both projects are situated on previously mined and underexplored land, and surrounded by successful, operating gold and base metal mines. Golden Range hosts approximately 950,000 oz gold resource and an existing 800 ktpa processing plant and associated infrastructure (placed on care and maintenance during 2019 by its previous owner). To the east of Golden Range is the Fields Find project, which contains significant levels of gold, copper and nickel.
Warriedar’s Big Springs gold project in Nevada, USA, is adjacent to First Majestic Silver’s Jerritt Canyon gold mine complex, an operating mine with a production history of over 10 Moz gold. Big Springs has an existing resource base of approximately 1 Moz gold within a granted mining licence, surrounded by approximately 93 square kilometers of prime exploration ground prospective for Carlin-style gold.
Warriedar also prides itself on the expertise and experience of its leadership team, driving the company towards successfully achieving its goals and increasing shareholder value. Geophysicist Dr. Amanda Buckingham serves on Warriedar's board of directors, bringing three decades of experience to her role. Mark Connelly, Warriedar’s non-executive chairman, is a financial and commercial executive with extensive experience in the resource industry. Dianmin Chen, a seasoned mining engineer, completes the complementary skill set of the board.

Key Projects
Golden Range
Situated in the middle of Western Australia's highly active Murchison exploration and mining province, the Golden Range project is strategically positioned between several major operating mines and advanced exploration projects. Together with the nearby Fields Find project, it represents a belt-scale opportunity, covering a combined area of 813 square kilometres.
A brownfields project with considerable past exploration and development, Golden Range hosts a gold resource of 945,000 ounces along a dominant central shear corridor. Existing on-site infrastructure includes an 800-ktpa oxide processing plant, which was placed on care and maintenance by the project's previous owner in 2019. This provides Warriedar with an accelerated, low-capital-intensity pathway to future gold production pending the success of an ongoing exploration program.
Project Highlights:
- Prime Location: Golden Range is bordered by multiple existing mines and deposits, each serving as a valuable analogue to the resources it may potentially contain. These include: Deflector Copper-Gold Mine, owned by Silver Lake Resources (ASX:SLR); Rothsay Gold Mine, owned by Silver Lake Resources; Mt. Magnet. owned by Ramelius Resources (ASX:RMS); Mt Gibson, owned by Capricorn Metals (ASX:CMM); and Golden Grove Copper-Zinc-Silver-Gold mine, owned by 29Metals (ASX:29M).
- Untapped Potential: Historical drilling at Golden Range was largely focused on shallow oxide gold in proximity to the existing mill, with an average drill depth of 42 metres. Historical pits on-site range in depth from 20 to 80 metres, with an average depth of 60 metres. This leaves substantial exploration upside for primary gold discoveries both below and along strike from existing shallow open pits.
- Exploration Results: Warriedar undertook an aggressive exploration program in 2023, which included drilling as well as airborne and ground electromagnetic (EM) surveying at both Golden Range and Fields Find. A total of ~ 36,000m of Reverse Circulation (RC) drilling was completed, resulting in the extension of 5 of the 5 gold Resources drilled (all in Mining Leases) and the advancement of several key Prospects. Importantly, the 2023 work highlighted where the 2024 focus should be – along the main mineralized shear within a 25 km long trend called the Golden Corridor. This trend already hosts 736 koz Au across 6 deposits and 16 historic pits. Results from 2023 and early 2024 included:
- Ricciardo (RDRC019): 32 m @ 3.59 g/t gold from 148 m (ended in mineralization)
- Ricciardo (RDRC020): 6 m @ 4.69 g/t gold from 142 m
- Ricciardo (RDRC002): 7 m @ 4.48 g/t from 251 m
- Ricciardo (RDRC031): 11 m @ 3.43 g/t gold from 149 m
- Windinne Well (WORC056): 4 m @ 5.17 g/t from 52 m
- Austin (AURC086): 20 m @ 1.98 g/t gold, 7.2 g/t silver, 844 ppm lead from 160 m
- Rothschild (BRRC083): 18 m @ 2.43 g/t gold from 191 m
- Mugs Luck (MLRC209): 8 m @ 2.28 g/t gold from 72 m
The Ricciardo deposit, an existing 476-koz resource in the middle of the Golden Corridor along the main shear. Assay results from drilling undertaken at the Ricciardo deposit confirmed the presence of high-grade shoots below existing oxide open pits and demonstrated the excellent exploration potential for further discoveries at Ricciardo
- Current MRE: The current mineral resource estimate for Golden Range is 945 koz contained within 19,429 kt at 1.5 g/t gold:
- 20 koz contained within 282 kt at 2.2 g/t gold measured.
- 441 koz contained within 8,887 kt at 1.5 g/t gold indicated.
- 485 koz contained within 10,080 kt at 1.5 g/t gold inferred.
- Exploration Roadmap: Warriedar has a clear line of sight on pursuing substantial resource growth and exploration success for its Western Australia projects. The focus during 2024 will be drilling for quality gold ounces to grow existing resources along the Golden Corridor, and drilling for new discoveries along the 70 km shear (ground all held by Warriedar).
Fields Find
The Fields Find Project and the location of key prospects.
Located just to the east of Golden Range, Fields Find is most notable for its highly irregular geology. Due to an intrusive complex within the greenstone sequence, the area is known to contain elevated levels of nickel, copper and gold. Although the brownfields project has been the site of previous exploration, the focus was exclusively on gold with one notable exception.
At Fields Find's southwest corner stands the historic Warriedar copper mine, which is located at the end of Warriedar's target zone, known as the Warriedar Corridor. It is also worth noting that the Murchison Province is generally known to be rich in copper with both the Golden Grove and Deflector copper mines in geological proximity.
Project Highlights:
- Copper Region: The Murchison province is known for its rich copper resource. Fields Find also encompasses the Warriedar Corridor.
- Exploration Results: Warriedar carried out a decent exploration program during 2023 which included drilling, airborne and ground-based EM surveying, at Fields Find. Results include:
- At the Rothschild gold deposit: the main gold lode along the entire strike length of the deposit was extended at depth by 150 m. Assay results included: 18 m @ 2.43 g/t gold from 191 m (BRRC083), 11 m @ 3.39 g/t gold from 197 m (BRRC081).
- New 2023 airborne electromagnetic (AEM) data covering a substantial part of the tenure which was previously un-flown. Follow-up ground EM identified several well constrained priority 1 targets, ready for drilling. Many of these are located with the layered mafic-ultramafic intrusion (the Fields Find Intrusive Complex).
- Drilling at Fields Find West confirmed a multi-phase porphyry intrusive system hosting polymetallic mineralisation comprising gold, copper, molybdenum and silver. At the Mopoke Prospect within this porphyry system, assay results returned 4 m @ 5.00 g/t gold from 92 m (MOR005).
Big Springs
Located in the prolific Nevada Gold Trend, the Big Springs Gold Project stands adjacent to First Majestic Silver's (TSE:FR) Jerritt Canyon Gold Mine Complex, which has a production history of more than 10 Moz gold. The project itself has an existing resource base of roughly 1 Moz gold and is surrounded by approximately 93 square kilometres of exploration ground prospective for Carlin-style gold.
Warriedar is currently collecting the necessary geoscience data to optimise its drill targets while also advancing its exploration permitting. It plans to recommence its drilling program upon approval of expanded permits, with a suitable partner.
The company believes the tenement package offers enormous untapped potential for growth in existing gold resources.
Project Highlights:
- Current MRE: The mineral resource estimate for Big Springs is 1,014 koz contained within 15,490 kt at 2 g/t gold:
- 129 koz contained within 860 kt at 4.7 g/t gold measured
- 428 koz contained within 6,000 kt at 2.2 g/t gold indicated
- 459 koz contained within 8,630 kt at 1.7 g/t gold inferred

Viani - Low Sulphidation Epithermal Gold Project License Renewed
Highlights
- MRD notified Alice Queen on Friday 19 July 2024 via email that its Viani license (SPL1513) has been renewed for a further three years with effect from Wednesday 3 July 2024.
- Viani, located on the Pacific Rim of Fire on Vanua Levu in Fiji, covers an area greater than 200km2 and is largely under explored (see Figures 1 and 2).
- The Dakuniba prospect within Viani has been previously sampled where epithermal gold mineralisation has been recorded in outcrop samples over a >3km strike length.
- Multiple epithermal veins within the Dakuniba prospect area, 5km by 1.5km surface gold-in- soil geochemical anomaly - the footprint of the epithermal mineralisation is comparable to other economically productive gold epithermal deposits globally.
- Previous drilling by Japanese International Cooperation Agency (JICA) in 1997 focused on a small, shallow part of the overall system and intersected high grade epithermal gold mineralisation.
- (Hole MJFV-5 (see Figure 3) over 6 vein zones at 50 to 100m below surface with best results, 0.6m @ 27.6 g/t Au & 900 g/t Ag and 0.4m @ 11.7 g/t Au1 and remains open in all directions.
- The JICA drilling was limited to only 600m of strike-length of the 5km long gold-in-soil anomaly (>10ppb Au) supported by epithermal geochemistry i.e., Ag and As.
- Based on discovery knowledge from epithermal systems worldwide, it is apparent the historical drilling was an inadequate test of the Viani gold system.
Alice Queen’s Managing Director, Andrew Buxton said,
We are delighted the SPL1513 license has been renewed for a further three years and look forward to continuing to work alongside the Fiji Mineral Resources Department as we commence our next phase of exploration activities. The Viani Gold Project is a tremendous prospect which has demonstrated it has the potential to become a significant epithermal system. With the license now renewed and the Company fully funded for its Fiji exploration plans, Alice Queen will continue the systematic exploration of the Viani Gold Project with the Company having commenced planning for its upcoming exploration programs.
Viani
Figure 1. Fiji Project locations.
Figure 2. Location of the Dakuniba Prospect in relation with SPL1513.
The Viani project (SPL1513) covers an area greater than 200km2 on the Caukadrove Peninsula on the Pacific Rim of Fire, Vanua Levu, Fiji. It is well serviced from Savu Savu on Vanua Levu and is highly prospective for a high-grade LSE gold system (see ASX releases 2 December 2022, “VIANI UPDATE” and 6 March 2023, “ALICE QUEEN UPGRADES VIANI EPITHERMAL PROJECT”.
Following a renewal process for Viani (SPL1513) which the Company commenced earlier this year (including as announced in the Quarterly Activities Report released to ASX on 23 April 2024), MRD notified Alice Queen on Friday 19 July 2024 that the license had been renewed with effect from Wednesday 3 July 2024 for a further three years. The renewed license includes typical terms for a license of this nature, including minimum work program and expenditure requirements.
Whilst the greater project area remains under explored, extensive sampling, trenching and (historic) limited drilling of the Dakuniba prospect area has been previously completed.
Previous drilling by JICA in 1997 returned multiple epithermal gold intersections in shallow drilling. Hole MJFV-5 (see Figure 2) intersected 6 vein zones at 50 to 100m below surface (best results include 0.6m @ 27.6ppm Au & 900ppm Ag, 0.4m @ 11.7ppm Au & 4.3ppm Ag)1. The JICA drilling was limited to only 600m of strike-length of the 5km long gold-in-soil anomaly (>10ppb Au) supported by epithermal geochemistry i.e., Ag and As.
Further details in relation to upcoming exploration plans at Viani will be announced in due course.

June 2024 Quarter - Activities Report
Highlights
- Multiple work programs focused on high-value critical minerals – scandium, cobalt, and copper across Rimfire’s NSW projects
- Thick zones of strong scandium anomalism from surface across multiple locations across the 20km² Murga Intrusive Complex;
- 22m @ 273ppm Sc from surface incl 12m @ 353ppm Sc
- 22m @ 172ppm Sc from 2m incl 5m @ 226ppm Sc
- 28m @ 158ppm Sc from 4m incl 6m @ 320ppm Sc
- 25m @ 163ppm Sc from 2m incl 5m @ 242ppm Sc
- 27m @ 162ppm Sc from 3m incl 4m @ 270ppm Sc
- Further Melrose leaching test work generates up to 90% scandium recoveries at atmospheric pressures
- Estimation of a combined JORC Mineral Resource for both Murga North and Melrose Scandium Prospects (Fifield and Avondale Earn-In Projects) underway ahead of completion within the coming weeks subject to receiving outstanding drill assays from the laboratory
- Drilling programs are planned for September 2024 Quarter designed to test copper cobalt targets at Broken Hill and scandium targets at Fifield
- Rimfire completes a placement to raise $1.15M post end of Quarter
Commenting on the Quarterly Activities report, Rimfire’s Managing Director Mr David Hutton said: “Rimfire continues to explore for and discover the critical minerals that are associated with global decarbonisation strategies. We are leveraged to and provide unique ASX investment exposure to scandium – an extremely valuable metal.
Buoyed by the success of our scandium drilling and metallurgical studies carried out during the Quarter we have made the decision to estimate a maiden JORC Mineral Resource for both the Melrose and Murga North Prospects with the work underway.
We expect to announce both resources in the coming weeks with just some Melrose drilling assays awaited on to complete the estimation process.
Looking ahead, the September 2024 Quarter will be pivotal for Rimfire and its shareholders with maiden scandium resources, further scandium drilling and the resumption of copper-cobalt drilling at Broken Hill”.
Introduction and Operational Summary
During the June 2024 Quarter (the “Quarter”), Rimfire’s exploration activities were focused on advancing the Murga and Melrose Scandium Prospects (Fifield and Avondale Earn In Project) with 100 aircore holes (2,664 metres) drilled.
The drilling successfully intersected strongly anomalous scandium at multiple locations across the Murga Intrusive Complex with subsequent re-assaying of anomalous drill samples demonstrating a significant increase in grade.
Buoyed by the success of the drilling, Rimfire has commenced the estimation of a combined JORC Mineral Resource for both the Murga North and Melrose Scandium Prospects.
Also, two further sighter leach tests focused on maximising scandium recovery at atmospheric pressures from Melrose laterite-hosted mineralisation returned recoveries of 62.6% and 90.1% scandium respectively. The latest results represent a significant improvement on previous best scandium recovery of 40% and can be attributed to increased acidity (sulphuric acid) and addition of reagents (NaCl).
To guide the Company’s future metallurgical studies, Rimfire also engaged highly experienced hydrometallugist Mr Boyd Willis as Process Consultant.
The exploration activities at the Fifield and Avondale are funded by Rimfire’s exploration partner
- Golden Plains Resources (GPR) and looking ahead to the September 2024 Quarter, Rimfire will complete the estimate of the combined JORC Mineral Resource for the Murga North and Melrose Scandium Prospects, as well as undertaking further aircore and diamond drilling at Murga to build on the initial resource.
Separately on its 100% - owned projects, Rimfire is preparing to carry out a further round of diamond drilling at its Bald Hill Copper Cobalt prospect commencing in August 2024.
