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.

Airborne EM over Multiple Targets on Ti-Tree Project
- Augustus Minerals has contracted UTS Geophysics to conduct a VTEM Max survey over several Copper, Cu-Ni-PGE, Zn-Pb-Ag and Uranium targets along the money Intrusion and within proximity of the prospective 85k long Ti-Tree Shear.
- The surveys will cover:
- The Money Intrusion, prospective for Cu-Ni-PGE mineralisation.
- Copper Ridge and Nics Bore over anomalous Copper Drilling results
- The Coo Creek prospect where drilling by Augustus in 2023 identified strongly anomalous Zn-Pb-Ag mineralisation.
- The Munaballya Well North area which shows potential for economic Uranium mineralisation.
- The surveys will help to advance the untapped potential of the Ti-Tree project to host economic mineralisation of multiple commodities.
Andrew Ford, GM Exploration
“The VTEM survey will provide key targeting data over three highly prospective and different prospects with potential for multiple commodities. Whilst the high prospectivity for copper mineralisation has been well documented, the addition of uranium and Broken Hill base metal style mineralisation highlights the quality of the underexplored Ti-Tree project”.
VTEM
UTS Geophysics has been engaged to conduct a helicopter borne VTEM Max survey comprising 646-line km over three separate survey areas. The system is excellent for locating discrete conductive anomalies as well as mapping lateral and vertical variations in resistivity which helps map structure, alteration and rock type. The system also collects magnetic data through a caesium magnetometer. The transmitter/receiver loop is suspended on a cable approximately 40m below the helicopter (Figure 1).
Figure 1 VTEM Max helicopter deployed electromagnetic survey arrangement.
Figure 2 Prospects and VTEM Survey areas.
Money Intrusion
The Money Intrusion, which has proven potential to host Ni-Cu-Co-PGE (platinum group elements), is part of the regional Mundine Well Dolerite Suite, a regionally extensive dolerite (strike length >80km). This extensive mafic intrusion, which is comprised of a variety of lithologies, including gabbro in the core, olivine dolerite on the chilled lower contact or keel and fine-grained dolerite on the outer edges. Mapping, aeromagnetics and multi-spectral imagery show that the Money Intrusion within the Ti-Tree Project covers a strike length greater than 16km, reaching widths >600m in the north of E09/23241.

Firetail Resources
Overview
Firetail Resources (ASX:FTL) is an Australian exploration company building a strategic portfolio of battery metals in Australia and Peru.
Batteries are a critical foundation of the transition to a greener and more sustainable future. Consequently, between electric vehicles and renewable energy, global demand for batteries is expected to increase from 185 GWh in 2020 to over 2,000 GWh by 2030. This is expected to have a profound impact on the market for battery and base metals such as lithium, nickel, cobalt and copper.
Firetail Resources aims to leverage this significant opportunity to find the critical resources to support the world’s journey to electrification. Under the direction of a proven board and management team with decades of collective experience in mining exploration, development and production, Firetail Resources boasts a diversified asset portfolio with multiple drill-ready targets and advanced exploration projects that all have tremendous potential to increase shareholder value.
Firetail's Australian Yalgoo-Dalgaranga, Mt. Slopeaway and Paterson projects are all located in proven geologic domains and display significant upside for substantial mineral resources. The company's more recent acquisition of two projects in Peru strongly complements these assets.
As the world's third-largest copper producer, Peru has a massive mining industry with a strong prominence in the country’s national economy. Long recognized as an excellent, low-risk mining jurisdiction, the country recently approved roughly $600 million worth of new mining projects. Unsurprisingly, nearly every major global mining company is either operating in the jurisdiction or is aware of it.
Although only recently acquired, Firetail's Picha Copper project is now one of its most promising assets. The Picha Project was acquired as part of a deal that includes a farm-in agreement with Barrick Gold Corporation (TSE:ABX) for an earn-in of up to 70 percent interest in the Charaque Project.
Picha is located along a NNW regional trend of carbonate-replacement (CRD) and epithermal deposits, including the San Gabriel Gold Project (Buenaventura NYSE:BVN), which is fully permitted and in construction; and the Berenguela Ag, Cu, Mn, Zn Deposit (Aftermath Silver TSXV:AAG).
In 2024, Firetail Resources announced the acquisition of York Harbour copper project, Canada. The company has signed a binding option agreement to acquire up to 80 percent of York Harbour project via a staged earn-in. York Harbour is a Cyprus-style volcanogenic massive sulphide (VMS) exploration project, located 180 km west-south-west of FireFly Metals Ltd (ASX:FFM) Green Bay copper project.
With a diversified portfolio of battery and base metals assets in two leading mining jurisdictions, Firetail is perfectly positioned to take advantage of the transition to green energy, driving considerable shareholder value in the process.
Company Highlights
- Demand for batteries is expected to exponentially increase by 2030, consequently driving the demand for battery and base metals.
- An Australian exploration company, Firetail Resources is well-positioned to take advantage of this market trend via a portfolio of Australian and Peruvian battery metals projects.
- Firetail's drill-ready assets are supported by smart field exploration and drilling programs to unlock their resource potential and increase shareholder value.
- The company's current portfolio of assets includes lithium, copper, cobalt, manganese, molybdenum, lead, zinc and nickel.
- All of Firetail's exploration activities are directed by a board and management team with a proven track record in mineral exploration, development and production.
Key Projects
Picha (Copper)
Located in Southern Peru's Moquegua and Puno departments, Picha represents Firetail's most recent acquisition. Intended as a complement to the company's portfolio of battery metals assets, the highly prospective 200-square-kilometre copper project hosts multiple drill-ready targets which Firetail plans to test in the coming months. Picha was obtained as part of a deal that included a farm-in agreement with Barrick Gold Corporation for the Charaque Project located 30 kilometres to the northeast.
Firetail recently confirmed its official drill permit for Picha and site preparations are underway for a October drilling campaign.
Project Highlights
- Promising Geology: Picha is located within Peru's Epithermal Au-Ag-Cu-Pb-Zn metallogenic zone along a north-northwest regional trend of carbonate-replacement and epithermal deposits.
- Nearby Projects: Picha is situated roughly 17 kilometres east-northeast of Compania de Minas Buenaventura's San Gabriel gold-copper-silver project, which hosts:
- Reserves of 14.9 Mt with 4.04 grams per ton (g/t) gold and 6.43 g/t silver representing 1.94 Moz gold.
- Resources of 24.86 Mt with 2.10 g/t gold and 8.46 g/t silver.
- Multiple Mineralisation: The project is prospective for multiple styles of copper mineralisation, including epithermal, stratabound, polymetallic carbonate replacement and porphyry-style. It also hosts several untested and geologically significant geochemical and geophysical anomalies, displaying similar mineralisation to the Storm/Seal copper project on Somerset Island.
- Significant Exploration Potential: Firetail has identified 13 exploration targets through a combination of geological mapping, surface sampling and geophysical surveys. Thus far, the company has collected 651 rock/chip samples and 289 soil samples and performed 118 line-kilometre IPs and 240 line-kilometre magnetic surveys. Highlights of its exploration work include:
- Widespread surface copper mineralisation coincident with IP anomalies.
- Channel Sample Results
- Cobremani: 41.6 metres at 1.12 percent copper and 22.85 g/t gold.
- Maricate: 17.6 metres at 1.95 percent copper and 29.58 g/t gold.
- Cumbre Coya: 32.85 metres at 0.61 percent copper and 209.76 g/t gold.
- Fundicion Target: Identification of a large chargeability anomaly reflecting potential sulphide mineralisation and/or alteration at depth indicative of a large porphyry body. This anomaly is roughly 2 kilometres long and 2 kilometres across at its widest point.
- Additional Drill Targets: Firetail's second IP survey revealed additional anomalies, including:
- Ichucollo: Semi-contiguous 2.5-kilometre long IP anomaly with coincident surface mineralisation and sample results of 24 metres at 1.08 percent copper, 13 metres at 1.38 percent copper and 30 metres at 0.79 percent copper. Manto-type mineralisation at the target's southern end also averages 1.45 percent copper over 18 metres.
- Huancune: A 1.5-kilometre long anomaly coincident with surface mineralisation. Multiple channel samples ranging from less than 0.5 percent copper up to 3.95 percent copper.
Charaque (Copper)
The Charaque Copper Project is located roughly 30 kilometres northeast of Firetail's Picha project, consisting of eight claims covering roughly 60 square kilometres. The region around the project is an active exploration area where multiple leading mining companies maintain significant landholdings, including Barrick Gold, Teck Resources (TSE:TECK.B) and Fresnillo (LON:FRES).
Charaque was acquired via a farm-in agreement between Firetail and Barrick Gold which entitles the latter to earn up to a 70 percent interest in the project.
Yalgoo & Dalgaranga (Lithium)
Firetail's Yalgoo and Dalgaranga lithium projects collectively span more than 1,750 square kilometres in Western Australia's highly prospective Murchison region. Located close to Geraldton Port and with easy access to all necessary infrastructure, the two projects host known lithium-caesium-tantalum (LCT) pegmatites with a strong rubidium association. Firetail recently completed a small maiden drilling program in the Johnson Well area of Yalgoo, itself the site of a historic lepidolite mine.
Rock chip sampling of surrounding areas is ongoing along with a detailed analysis of lithium prospectivity. Results and a project update are expected within four to six weeks.
Project Highlights
- Yalgoo Exploration Results: Thus far, exploration at Yalgoo has returned highly promising results, including:
- A 25-kilometre "Goldilocks Zone" at Yalgoo confirmed to host LCT pegmatites with historic results of up to 3.75 percent lithium oxide.
- Rock chip assay results of up to 0.54 percent lithium oxide and under 1 percent rubidium.
- High-grade rubidium, including 10 metres at 0.44 percent rubidium from 10 metres.
- Dalgaranga Exploration Results: Firetail has completed detailed geological mapping in the project's north, returning anomalous lithium, rubidium, caesium and tantalum values indicative of LCT pegmatites. The company plans to undertake further mapping in the area.
- Dalgaranga's Strong Prospectivity: Dalgaranga counts several advanced critical minerals projects amongst its neighbours which together confirm its prospectivity:
- King Tamba (ASX:KTA): Maiden mineral resource estimate (MRE) of 5 Mt at 0.14 percent rubidium oxide with a lithium oxide credit. Open mineralisation in all directions with a planned infill drill program to expand MRE.
- Aldoro Resources Limited (ASX:ARN): Aldoro's Niobe Tantalum-Lithium project has delivered a maiden inferred JORC MRE of 4.6 Mt at 0.17 percent rubidium oxide and 0.07 percent lithium oxide. Potential to upgrade is present thanks to mineralisation at shallow depth.
- Farm-in Agreement on Southern Yalgoo Tenement: Completion of the farm-in agreement completed with SensOre (ASX:S3N), through its joint-venture subisidiary Exploration Ventures AI Pty (EXAI) in partnership with German resource investment group Deutsche Rohstoff AG, on tenement E59/E2252, a part of the Firetail Yalgoo Lithium Project. As per the agreement, EXAI is to earn up to 80 percent of lithium rights on E59/E2252 by spending $3.5 million in two stages. Additional considerations of up to $600,000 will be fulfilled upon the delivery of maiden mineral resource estimate (MRE) and pre-feasibility study (PFS). SensOre will further provide Firetail access to its proprietary AI technology across the Yalgoo and Dalgaranga Lithium Projects. The two companies will work closely together to identify and confirm Lithium exploration targets in the region.
Mt. Slopeaway (Nickel)
Situated in Central Queensland, Firetail's Mt. Slopeaway Nickel Project contains an existing JORC 2012-compliant inferred mineral resource of 4 MT at 1 percent nickel, 0.2 percent cobalt and 1 percent manganese. Having recently been awarded project status, Firetail plans to conduct environmental and heritage surveys. Planning of an onsite drilling program is also underway.
Project Highlights
- Current Progress: In addition to drilling, heritage and environmental surveys, highlights of Firetail's work at Mt. Slopeaway include:
- Development of a geological model indicative of a manganese-cobalt-nickel layer at the base of a limonite section.
- Finalisation of a project land access agreement and completion of site earthworks.
- Phase 1 reverse circulation (RC) drilling with results exceeding historical nickel and cobalt assay data.
- A planned Phase 2 RC and diamond drilling program to upgrade the project's current resource classification.
- Extensional drilling to potentially expand the project's current inferred resource.
- Drilling Results: A drilling program completed in Q4 2022 returned up to 51 metres of thick laterite nickel-cobalt mineralisation.
Paterson (Copper)
Firetail's Paterson Copper Project spans five tenements across roughly 1,000 square kilometres in Western Australia. Heritage agreements for the project are in place and desktop studies are currently progressing, with multiple prospective target areas identified for drilling.
Project Highlights
- Shallow Intercepts: Paterson displays the shallowest known historical gold/copper intercepts in the region, with up to 6.5 percent copper, 0.99 g/t gold and copper, 0.99 g/t gold and 1,330 parts per million (ppm) molybdenum across an approximately 50-metre wide magnetite alteration zone.
- Drilling Targets: Paterson has identified the following potential targets for drilling at Paterson:

Aura Increases Tiris’ Mineral Resources by 55% to 91.3 Mlbs U3O8
KEY POINTS:
- Tiris’ global Mineral Resources increased by 55% to 91.3 Mlbs U3O8, up from 58.9Mlbs U3O81 (global Mineral Resources includes Tiris East and Oum Ferkik Project areas)
- The recent 15,262m drill program delivered a very large 28.9 Mlbs U3O8 increase in the Tiris East Uranium Project’s Mineral Resources, totalling 76.6 Mlbs U3O8, delivered at a discovery cost of only US$ 0.14 per lb U3O8
- Measured and Indicated Mineral Resources increased by 35% adding 10.3 Mlbs U3O8 providing further confidence to the Front End Engineering Design (“FEED”)2 production schedule
- Drilling results and the increase in Mineral Resources both demonstrate significant future resource growth potential at Tiris from ongoing exploration activities
- The major increase in the Tiris Mineral Resources:
- Reinforces Auras’ commitment to progress Tiris towards a development decision in late 2024 or early 2025;
- Offers significant potential to materially enhance the already excellent FEED economics of NPV8 US$ 388 M and IRR 36% after tax3,4, and
- Presents real opportunities to increase the Project’s future scale beyond the current 17-year mine life at 2 Mlbs pa U3O8 production
- Additional Mineral Resources were defined from extensions to known mineralisation and exhibit the same characteristics as the current shallow free digging mineralisation that has proven exceptional beneficiation characteristics
- Mine scheduling and optimisation including a review of the Ore Reserve Estimate will now be undertaken on the enhanced Mineral Resources
Aura Energy’s Managing Director and CEO Andrew Grove said:
"The resource growth at Tiris confirms our view that this is an important uranium province with the capacity for further growth upside.
The Board believes that the very significant increase in Mineral Resources resulting from the successful drilling campaign will have a materially positive impact on Tiris’ economics and has been delivered at a very low discovery cost of just US$ 0.14 per lb.
Mineralisation was identified not only from high strength radiometric anomalies, but from areas of low strength anomalies, significantly increasing the exploration potential of the area as these low-level anomalies have been ignored in past exploration.
More opportunities remain to expand the known mineralisation within the current granted tenements. In addition, the potential for future discoveries within the 13,000km2 of new tenement applications is significant as we have only just begun exploration over this district-scale opportunity.
The increased Mineral Resource inventory will further support the funding and development of the Tiris Uranium Project in the near future.”
Tiris Global Mineral Resource Estimate reported using a 100ppm U3O8 cut-off grade, see Table 1 for details
The drilling program undertaken in 2024 has delivered a major increase to the Project’s Global Mineral Resources totalling 184 Mt at 225ppm for 91.3 Mlbs U3O8 at a 100ppm cut-off grade. This is a 55% increase in the contained U3O8 from the previous MRE, reported in 2023, of 113Mt at 236ppm for 58.9Mlbs5 U3O8.
This drilling program was aimed at assessing additional resource potential at Tiris East and delivered a 10.3 Mlbs or 35% increase of Measured and Indicated (“M&I”) Resources, which stands at 83 Mt @ 219ppm for 39.9 Mlbs U3O8, and a 76% increase in total Inferred Resource, which stands at 102 Mt @ 229ppm for 51.4 Mlbs U3O8. The detail of the upgraded resource across the project areas and the previous resources are shown in Table 1.
In April 20246, Aura completed an air core (“AC”) drilling program of 2,995 holes for 15,262 metres, a 37% increase in the total number of holes available for resource calculations, to evaluate a previously announced exploration target of between 8 Mlbs and 32 Mlbs7. The Mineral Resource increase of
32.4 Mlbs U3O8 exceeded the upper end of the exploration target range, providing strong support to Aura’s exploration methodology, and is a strong indication to the mineralisation potential that may be available in regional leases that are currently under application8.
In addition to targeting extensions to known mineralisation, and testing previously un-drilled radiometric anomalies around Tiris East, the program considered several conceptual targets over low- level radiometric anomalies. Several of these conceptual targets returned very positive results, further increasing exploration potential of the area. This is a major change from previous exploration in the area.
Mineral Resource estimates were undertaken utilising Multiple Indicator Kriging (“MIK”) estimation methodology and recoverable Mineral Resources reported using a 10x10x1m Selective Mining Unit (“SMU”). The Competent Person for the 2024 Tiris Mineral Resource Estimates is Mr Arnold van der Heyden of H&S Consulting Pty Limited (“HSC”).
