Anax Metals Ltd ( ASX: ANX) (Anax) and Develop Global Ltd (ASX: DVP) (Develop) are pleased to provide an update on the progress of the Scoping Study announced in March 2024 investigating options for processing select oxide and transitional ores from Sulphur Springs at Whim Creek.1 The Whim Creek Copper-Zinc Project, located 100 km southwest of Port Hedland, is jointly held by ANX (80%) and DVP (20%). Develop’s 100%-owned Sulphur Springs Zinc-Copper project is located 115 km south-east of Port Hedland and 150 km east-southeast of Whim Creek.
- Bench scale tests on Sulphur Springs oxide and transitional ore demonstrate excellent leaching amenability
- High grade transitional and oxide copper recoveries between 80-95%
- High grade transitional zinc recoveries ranged between 95% and 99%
- Whim Creek bacteria used to enhance the leaching process
- High zinc recoveries could unlock significant value for the joint venture through zinc sulphate production
- Acid production from the leaching process potentially a valuable byproduct
Anax’s Managing Director, Geoff Laing commented:“The Anax team has applied the considerable knowledge and learnings, including from the Whim Creek heap leach programme over the last three years, to deliver outstanding outcomes in this preliminary round of test work. Heap leaching of copper oxide and transitional ores is commonly practiced, and the Sulphur Springs ore has demonstrated excellent amenability to the process conditions we have applied. We are excited to have demonstrated the excellent response of zinc dissolution to the process as this may facilitate the production of zinc sulphate, a key additive to fertilisers.”

Sulphur Springs Project
The Sulphur Springs Project is an advanced pre-development Project with a JORC compliant resource of 13.8 Mt @ 1.1% Cu, 5.7% Zn and 23.5 g/t Ag. 2 In June 2023, DVP announced the results of an updated Definitive Feasibility Study (DFS) for the Sulphur Springs Project, which identified an ore Reserve of 8.8 Mt @ 1.1% Cu and 5.4% Zn that will be processed through a new 1.3 Mtpa concentrator.
ANX and DVP have identified high-grade oxide and transitional ore outside the mineral inventory, reported by DVP in the Sulphur Springs DFS,3 that may be amenable to heap leaching. The Scoping Study is investigating the feasibility of transporting oxide ores from Sulphur Springs to the fully permitted Whim Creek, where ore may be heap leached to produce saleable copper and zinc products.
Sulphur Springs Test Work Samples
Key to the strategy is demonstrating the metallurgical amenability of the Sulphur Springs ores to heap leaching at Whim Creek. Heap leaching of oxide, supergene and transitional ores is common practice within the industry and the refurbished Whim Creek heap infrastructure provides an opportunity for the joint venture partners to enhance the value of both projects.

Anax Metals Limited
Investor Insight
Anax Metals is an ASX-listed exploration company looking to develop its copper assets in the Pilbara Region of Australia. It has important joint ventures and partnerships that can facilitate the execution of a strategic processing hub to offer a compelling investor value proposition.
Overview
Anax Metals (ASX:ANX) is a project developer that is on track to begin producing copper and zinc concentrates from its flagship Whim Creek project located in the Pilbara region of Western Australia. The project is 80 percent owned by Anax, with JV partner Develop Global (Develop) owning the remaining 20 percent. The Whim Creek DFS (and leaching study) have demonstrated the opportunity for an eight-year mining operation producing copper concentrates, cathodes and valuable byproducts. The operation will generate $410 million in cash flow and deliver an NPV of $270 million with a development capex of $71 million.
The company believes its growth potential lies both in expanding the mineral resources across the project’s four deposits and a consolidation strategy that includes a processing hub with a concentrator and heap leach at Whim Creek. Benefits from the consolidation include delivering economies of scale with processing flexibility to treat ores from regional orebodies. The permitted infrastructure is ideally located and suited to becoming the Pilbara-processing hub.,
Anax Metals and Develop have commenced a scoping study to evaluate the potential for treating high-grade oxide/transitional ores from Develop’s wholly owned Sulphur Springs project on the Whim Creek heap.
During the second quarter of 2024, Anax Metals and GreenTech Metals announced they had signed a non-binding and non-exclusive memorandum of understanding to assess the potential to treat mined material from GreenTech’s base metal assets, with a focus on the open-pittable Whundo deposit.
Anax Metals also signed a non-binding and non-exclusive memorandum of understanding (MoU) with Artemis Resources (ASX:ARV) to jointly assess the potential for processing the copper content of Artemis’ open-pittable Greater Carlow resource at the fully-permitted Whim Creek Processing hub. Anax and Artemis also agree to evaluate the potential for Artemis to explore for gold mineralisation on the Anax project tenure.
Whim Creek Pit
Since acquiring the project in 2020, Anax Metals has increased its contained metal resource inventory by over 57 percent. At the end of the second quarter of 2024, Anax Metals signed a contract with drilling company Topdrill for up to 1,700 metres of diamond drilling. Diamond drill rigs have been mobilized at site with the primary goal of testing the down-plunge extensions of the high-grade copper zones at the Evelyn deposit. Previous drilling intersected 13 m @ 4.46 percent copper, 3.10 percent zinc, 45 g/t silver and 1.61 g/t gold from 204 m. Evelyn remains open down plunge with lots of expansion potential.
Company Highlights
- Focus remains on delivering near-term copper production, within the next 18 to 24 months, at the Whim Creek copper-zinc project, which will generate in excess of $400 million in free cash flow over an eight-year mine life.
- The company’s growth strategy includes delivering both resource growth and consolidation of copper assets in the Pilbara region through the development of a central processing hub.
- Since completing the DFS last year, Anax Metals has been considering the potential to expand the production capacity of Whim Creek infrastructure beyond 20 kt of copper equivalent per year.
- Capital requirements are anticipated to be low as Anax Metals plans to utilise substantial existing infrastructure and implement preconcentration technology to reduce process capacity requirements.
- The company is currently working with key partners, including Develop Global (ASX:DVP), Greentech Metals (ASX:GRE), and several metal trading groups.
Whim Creek Copper Zinc Project
Whim Creek is located 120 km from both Port Headland and Karratha on the NW Coastal Highway in the Pilbara region of Western Australia. The project has a long history of copper production with existing infrastructure that includes dams, haul roads, offices, workshops and a dedicated gas spur line to site. The project is currently being developed as a joint venture (80/20) between Anax Metals and Develop Global. The project has four main deposits, namely Whim Creek, Mons Cupri, Salt Creek and Evelyn, with structurally controlled, volcanic-hosted massive sulphide style copper-zinc-lead mineralization.
Production – Concentrator and Heap Leach
Since completing the definitive feasibility study in 2023, Anax has promoted Whim Creek as a regional processing hub, with potential for an expanded production capacity in excess of 20 kt copper equivalent. Highlights of the technical report include FCF generation of $410 million over an eight-year mine life. Processing would be predominantly through the planned concentrator. Heap leaching is anticipated to begin in the second year of production.
A processing hub with sorting, concentrator and heap leach facilities
The company believes the project will also provide a processing solution for surrounding projects located within trucking distance of Anax’s processing facility. Longer term, Anax plans to establish a Pilbara Base Metal Alliance to facilitate collaboration with other base metal projects in the region.
Exploration
The project exploration tenure is located in the highly prospective Archean granite-greenstones of the Pilbara region, encompassing the width of the Whim Creek Greenstone Belt. Near mine extensions to known copper-zinc-lead VMS resources remain underexplored with potential at Mons Cupri South for the discovery of a new intact Mons Cupri-sized deposit. VMS-style alteration and mineralisation have been intersected over 1km. The two satellite deposits at Salt Creek and Evelyn have excellent down plunge and strike potential for blind massive sulphide shoots and drilling is under way at Evelyn.

Exploration Update - Visible Gold Intersected at Salanie
HIGHLIGHTS:
- Visible gold identified in drilling at the A1 prospect at 19m depth (Figure 1), associated within a broader 13m zone of quartz veining and shearing from 9.6m downhole:
- Interpreted as extension to system in trench SATR001 (10.3m @ 3.4g/t Au and 1.4m @ 15.7 g/t Au) (Figure 5);
- Assays for this hole are pending.
- At P6, a significant quartz veining/shear system over 20m with associated sulphides has been identified along the trend of historical high-grade underground workings that produced at an average of 16g/t Au.
- The underground workings at P6 represent a priority target that will be further targeted in the 2025 drill season:
- System displays as quartz veining and associated visual estimates of sulphides (trace to 25% pyrite+/-chalcopyrite) intersected in three principal positions in drillhole SLDD002 (61- 65m; 71-75m and 84-87m).
- Drilling completed for the current field season, with discussions advanced with a highly reputable new drilling contractor for drilling in 2025.
- At Salanie, five holes for 328m (two at the P6 prospect and three at the A1 prospect) were completed (two of these did not reach target depth due to drilling performance), with assay results received for 3 holes.
- In the northern areas around the Mikouma and Binda prospects, infill soil sampling has strengthened existing gold targets in these regions with anomalies up to 200ppb Au. Follow up ground reconnaissance will assist in delineating further the drill targets.
- Company to undertake a one (1) for three (3) non-renounceable entitlements offer to raise approximately $3.25 million (before costs).
Figure 1: Examples of visible gold identified in SLDD004 – at 19.04m (associated with chalcopyrite (Cpy) and galena (Gn)).
The Company cautions that visual estimates of sulphides or mineral abundance should never be considered a proxy or substitute for laboratory analysis. Laboratory analysis would be required to determine the widths and grades of sulphides, visible gold, or suspected mineralised intervals reported herein. Visual information also potentially provides no information regarding impurities or deleterious physical properties relevant to valuations. Assays are expected within 3-5 weeks.
Apollo Minerals’ Managing Director, Mr Neil Inwood, commented:
“The first pass drilling is highly encouraging having identified visible gold associated with quartz veining at A1 and a significant shear/quartz vein system at P6. Assays are pending from the key holes at A1. The Salanie system is interpreted to be in the same regional trend of Archean greenstones as Managem’s 1m oz Eteke deposit; highlighting the potential in the broader system.”
“Unfortunately, a combination of late arrival and poor performance from the drilling contractor and the end of the field season has meant that less than a quarter of the planned holes for 2024 were completed and the P6 target was only partially tested by one drill hole. We are in advanced discussions with another drilling company to commence drilling in the new year. Such a partner will enable a significant increase in drilling rate and quality and enable us to further unlock the untested potential at the Salanie Gold Project.”

Wadi Al Junah VMS-Style Copper-Zinc-Gold-Silver Project in Saudi Arabia
Highlights
- As announced on 6 November, MBK’s Saudi Arabian JV company, has been awarded the Wadi Al Junah Project as part of the Saudi Government’s Exploration Licensing Round 6
- Wadi Al Junah is prospective for volcanogenic massive sulphide (VMS) copper-zinc- gold-silver mineralisation and for shear zone gold-silver, with several untested priority targets
- The Project is 35km east of the Al Hajar Au-Ag-(Cu-Zn) deposit previously mined by Ma’aden and is proximal to the regional centre of Bisha, and close to major access routes, local towns and workforce
- Saudi exploration strategy is supported by a well capitalised in-country JV Company in CMC and significant Saudi government incentives to de-risk and fast-track exploration
- Metal Bank continues to assess new potential project areas in Saudi Arabia prospective for copper, gold and other critical minerals – several tenement applications in progress
CMC is a Saudi Arabian limited liability company owned by MBK (60%) and Central Mining Holding Company (‘CMH’, 40%). CMH is a member of the Al Qahtani Holdings group, and was the JV partner of Citadel Resources which, under the leadership of Inés Scotland as Managing Director, was responsible for the exploration and development of the Jabal Sayid copper project in Saudi Arabia (prior to its acquisition by Equinox). CMC will be responsible for managing and implementing the work program for the Wadi Al Junah project utilising the technical expertise of MBK, as the exploration JV partner, in combination with the KSA expertise of the Al Qahtani Group. CMC has a current capitalisation of SAR5m (~AUD2.1m).
Wadi al Junah with an area of 427km2 was the largest of the projects offered in Round 6 and is proximal to the major regional centre and airport of Bisha, with major access routes passing through the license area and local towns and workforce close by. The Project is located in the prospective Wadi Shwas Gold Belt, a region under-explored for shear zone gold, VMS copper-zinc-gold-silver and intrusion-related gold and base metal deposits. It is supported by several mineral occurrences with encouraging geological observations, and gold, silver and copper grades in historic regional- scale reconnaissance mapping, which have not been followed up by modern work.
MBK’s technical team has prepared a comprehensive two-year work program, with an initial focus on following up the previous limited and surface based exploration for mineral occurrences of copper, gold and silver. MBK is aiming to be drill-ready within the next six months.
Commenting on this acquisition, Metal Bank’s Chair, Inés Scotland said:
“The successful tender for the Wadi al Junah project in Saudi Arabia by our JV company CMC via a tightly contested and highly competitive exploration round speaks to our commitment, capability and technical expertise in achieving our strategy of acquiring prospective tenure within Saudi Arabia, which we believe remains underexplored and highly prospective.
Wadi al Junah represents our first project back in Saudi Arabia, a region in which MBK’s management team has extensive experience and a proven track record of success, having previously developed the Jabal Sayid project. We are well-supported by both our JV partner and the significant government incentives provided by the Kingdom of Saudi Arabia in search for the next Jabal Sayid. The Arabian Shield has so much underexplored potential, and we are ready to get our initial phase of exploration underway as quickly as possible.”
Wadi al Junah Copper-Zinc-Gold-Silver Summary
The Wadi al Junah project area covers an area of 427sq km within the Asir province of the Arabian Shield, southwest Saudi Arabia (Figures 1 and 2). It is approximately 375km south-east of Jeddah, 150km east-northeast of the port of Al Quinfidhad and around 35km east of the Al Hajar Au-Ag-(Cu- Zn) deposit previously mined by Ma’aden. It is proximal to the major regional centre and airport of Bisha, with major access routes passing through the license area and local towns and workforce close by. The majority of the project area is accessed by local tracks and wadi valleys in moderate topography.

Figure 2: Wadi al Junah location map within the Arabian Shield showing major geological provinces and major Au and Cu mines (modified from KSA Ministry of Industry and Minerals publication after Nehlig et al, 2002)
Geology
Wadi al Junah is situated within the central Asir terrane of the Archaean Arabian Shield (Figure 2) within the ~80km long north-trending Wadi Shwas Gold Belt. The Shwas VMS belt on the western margin of the Wadi Shwas Gold Belt is host to the Al Hajar Au-Ag-Cu-Zn deposit, and numerous other VMS base metal and Au mineral occurrences of Proterozoic age are present in the region (Figure 3).
Three known mineral occurrences occur in the tenement area – Haniyat (Ag-Cu-+/-Au+/-Zn), Wadi al Maytha (Ag-Cu) and Wadi Umm Rahka (Ag-Cu). Very limited rock chip sampling as part of regional scale mapping work in the 1960’s and 1970’s includes results up to 1.53% Cu, 0.44g/t Au and 160g/t Ag from these prospects, which were never followed up1.

Octava to Commence Drilling at Yallalong High-Grade Antimony Project
Highlights
- Drill rig relocating to site with drilling to commence this weekend.
- The 3000m reverse circulation (RC) drill program is targeting further high-grade antimony at the Discovery prospect.
- Historic drilling at Discovery recorded high-grade antimony intercepts over a strike length of ~300m and remains open. Results include:
- 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
- After drilling at Discovery, the drill rig will relocate to the Central antimony target, 2km north along strike. There has been no previous drilling at Central.
- A detailed geophysical survey over the antimony corridor at Yallalong is now complete, with the data being processed. This is expected to generate further targets within the antimony corridor.
Octava’s Managing Director Bevan Wakelam stated, "It’s great to have the rig heading to site and earlier than we had planned. The drilling will start on Discovery, then move to the Central target and should take about 2 weeks to complete. High-grade antimony has already been intersected at Discovery over a significant strike length and this drilling will further test the size. We will also twin some of the previously drilled holes."
Figure 1. Planned drill hole locations at the Discovery antimony target - Yallalong Antimony Project.
The antimony (Sb) mineralisation identified at Yallalong appears within a 10km north-south striking mineralised corridor that is interpreted to be related to a structural belt between the regional scale Darling and Woodrarung faults. Previous exploration identified four principal antimony targets where antimony mineralisation was exposed at surface. 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.
Figure 2. Antimony targets at Yallalong antimony project with underlying geology.
Drilling at Discovery target recorded some of the highest-grade antimony drill intersections in Australia, at shallow depth, over a strike of ~300m 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
- YRC27: 6m @ 1.35% Sb from 13m
After drilling at the Discovery target is complete, the rig will then move to the Central target, which is located 2 kilometres north along strike. There has been no previous drilling at the Central target.

Targeted Exploration Focus Delivers an Additional 471koz or 99% Increase in Ounces, and a Higher Grade for Ricciardo
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).
