Kihabe-Nxuu Polymetallic Project Silver/Gallium Potential
In response to recent enquiries, Mount Burgess Mining Ltd (MTB:ASX, the “Company”) is pleased to update the silver potential of the Kihabe-Nxuu Project (“Project”) in Botswana. With the recent increase in silver prices and multiple forecasts predicting a structural deficit over the coming years, the importance of the silver content of the Project has increased substantially.
HIGHLIGHTS
- Kihabe Mineral Resource Estimate (21 million Tonnes at 2.0% ZnEq1) estimated to contain 5.4 million Oz of silver.
- Silver currently trading at or near 10-year highs at US$30 per Ounce2 (Figure 1)
- Estimated silver deficit of 215.3 million troy ounces in 20243
- Individual silver intersections at the Kihabe Deposit include:
- 7m @ 984g/t (31.6oz/t) from 97m incl. 1m @ 4,076 g/t (131oz/t) from 97m (KDD114)
- 7m @ 477g/t (15.3oz/t) from 63m incl. 1m @ 1,510 g/t (48.5oz/t) from 65m (KIH007)
- 50 holes in the SW domain, over a strike length of 550m, average 49.7g/t (1.6oz/t) Ag4
- 31 holes in the NE domain, over a strike length of 900m, average 63.67g/t (2.0oz/t) Ag5
- Metallurgical test work underway to determine onsite recovery of Gallium and Germanium not yet included in the Kihabe Mineral Resource Estimate. Kihabe Deposit has a large Exploration Target of up to 100 million tonnes @12 g/t Gallium.
- Gallium currently trading at US$811.2/kg6
The Kihabe Deposit has two significant silver domains with shallow high-grade intersections including 7m @ 984g/t from 97m and 7m @ 477g/t from 63m, previously announced in June 2021. The SW and NE domains require further infill and extensional drilling. The Company is taking this opportunity to update the market by releasing individual metres over 93g/t (3oz/t) in the following tables. Individual metres of 311g/t (10oz/t) and over, are highlighted in green. Refer to attached Figures outlined in Drill Section headings in the table to review the intersections from which the individual metres have been extracted.
The 6 million tonne Nxuu Mineral Resource Estimate, 7kms to the East of the Kihabe Deposit, contains a further 1,040,000 ounces of silver.
The Company is also undertaking metallurgical test work to determine the recovery of Gallium and Germanium onsite. Results will be released once available. Further drilling is required before the Gallium Exploration Target (refer ASX Release 6 July 2023) and Germanium can be included in the Kihabe Mineral Resource Estimate. Gallium and Germanium have been included in the Nxuu Mineral Resource Estimate.
Chairman of Mount Burgess Mining Mr. Nigel Forrester commented:
“The importance of the silver content of the Kihabe-Nxuu Project is supported by its recent significant price increase to 10-year highs. The Company sees this as being positive for the Project as the expectation is that silver demand will continue to increase due to the metal’s green technology use in solar panels, batteries and wind turbines.
The importance of the gallium content of the Kihabe-Nxuu project is also supported by its recent significant 272% price increase to US$811.2/kg since January 2020. The increase is primarily due to gallium nitride chips required to replace silicon chips not able to cope with the increase in heat generated from the increase in 5G communication traffic in computers, laptops and smart phones.”

Airborne EM over Multiple Targets on Ti-Tree Project
Augustus Minerals (ASX: AUG; “Augustus” or the “Company”) is pleased to announce that an airborne Versatile Time Domain Electromagnetic (VTEM) Max survey will be undertaken at three areas within the 3,600km2 Ti-Tree Project in the Gascoyne Region. The survey is scheduled for August.
- 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.

Registration Opens for the Inaugural Mining, Metals and the Circular Economy Conference
Early bird delegate passes are now on sale for the inaugural Mining, Metals and the Circular Economy conference, scheduled to take place at the ICC Sydney on 29 & 30 October 2024.
The launch of this event is timely, as circularity in the mining and metals industry is important for reaching net-zero goals and global decarbonisation, while also addressing the rising demand for minerals required for future technologies and other vital materials.
Organised by Beacon Events, the Mining, Metals and the Circular Economy conference will be co-located with the International Mining and Resources Conference (IMARC), providing attendees with unprecedented access to industry experts and thought leaders in the mining sector, fostering a dynamic exchange of innovative ideas and best practices. What sets this conference apart is that it is the world’s first and only event to explore the global context of process and product circularity throughout the mining industry’s value chain.
Sherene Asnasyous, Event Director at Beacon Events, explained that the strategic development of Mining, Metals and the Circular Economy is about helping mining companies, as well as their customers, partners, and suppliers, better comprehend their roles within the circular value supply stream.
“As a powerful tool to reduce waste and pollution, circularity needs to be a priority for mining producers and their supply chains. It is also crucial for meeting the growing demand for minerals needed for new technologies, construction, and other industries, as it extends the lifespan of metals beyond their initial use. We encourage companies involved in the mining value chain to join us in this forum to explore ways to reduce waste at all stages of a mine site’s lifecycle and capitalise on the economic benefits of extracting valuable materials from waste and metals recycling,” Ms. Asnasyous said.
The introduction of Mining, Metals and the Circular Economy to the mining value chain's events calendar offers businesses a focused and in-depth opportunity to implement circular economy practices as a solution to address the current environmental and supply chain challenges faced by the industry.
“Mining, Metals and the Circular Economy is a valuable opportunity for industry players to come together because no single organisation has all the solutions to applying circularity to their business operations. It requires diverse insights and skills, as well as collaboration, to help find better ways to mine and be more resource efficient. The conference program features international and local experts from leading mining companies, consultancy firms, industry associations, and academia. Our speakers will cover a range of important topics including mine rehabilitation, waste commercialisation, policy and regulation, recycling metals, and circularity tracking and reporting,” Ms. Asnasyous said.
Alan Young, Senior Advisor at Circular Economy Leadership Canada and a panellist on Day 1 of the conference, underscores the importance of implementing circular economy principles across all participants in the minerals value chain.
"With the minerals-intensive reality of the green energy transition, there is an urgent imperative to re-invent the way we access and use metals, from the mine site to their end use in cars, batteries, computers and renewable energy systems. An integrated circular economy framework allows all participants in minerals value chains to contribute to the vision of a zero waste/zero carbon approach to these vitally important materials, while creating a massive economic benefit for society,” Mr. Young emphasised.
Gustavo Roque, General Manager – Future Use at Vale in Brazil, another international speaker headlining the conference, is looking forward to presenting on reclaiming post-mining landscapes to leverage social, economic and natural assets.
“My participation in the event will facilitate valuable exchanges of ideas and foster collaborations that can propel the industry toward more sustainable and efficient practices. Engaging with global experts and leaders at these events aligns perfectly with our objectives to redefine the mining landscape through innovation,” Mr. Roque said.

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

- 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”).

Latest Assays Demonstrate Significant Increase in Murga Scandium Grades
Rimfire Pacific Mining (ASX: RIM, “Rimfire” or “the Company”) is pleased to advise that re-assaying of aircore drill samples from the Murga Scandium Prospect has demonstrated a significant increase in scandium grade for the prospect, which is located on Rimfire’s Fifield Project 70kms NW of Parkes NSW (Figure 1).
Highlights
- Re-assaying of March 2024 aircore drill samples increases average scandium grade by 11% with some samples achieving 25 – 50% increases
- Maiden Murga North JORC Resource to be estimated in conjunction with Melrose maiden JORC resource estimate
- Planning for further aircore and diamond drilling to determine the lateral extents and infill wide spaced anomalies of the scandium at Murga underway
- All scandium exploration funded by exploration partner GPR with a further $250K received during the last month
This is a significant development as the re-assay data demonstrate that the actual scandium grades for Murga could be significantly higher than the original drill intercepts previously reported by Rimfire and reinforces the potential of Murga to host a large-scale pure scandium resource.
On the back of these great results, Rimfire has decided to estimate a JORC resource for the Murga North portion of Murga, which will be carried out in conjunction with the upcoming Melrose JORC resource estimate”.
Re-assaying of Samples
Original assaying of drill samples from the reconnaissance March 2024 Murga aircore drilling program was undertaken using a 4-acid digestion / ICP analysis technique which is considered a “partial digest” analytical method and was used by Rimfire to cost effectively “screen” large numbers of drill samples generated by the drill program (see Rimfire’s ASX Announcement dated 6 May 2024).
Having identified multiple scandium occurrences at Murga (i.e. Murga North, Murga Northwest, Murga East and Murga South, Rimfire subsequently resubmitted 260 of the most anomalous samples (greater than 120ppm Sc) from the drilling for additional scandium analysis using the more expensive lithium borate fusion XRF method.
This technique is a “whole digest” analytical method whereby a fused disk of the sample is created and analysed with XRF spectroscopy. The assay grade achieved by this method is considered to be a more representative scandium assay value.
The additional assaying aimed to confirm and potentially increase the scandium assay values obtained from the 4-acid digestion / ICP analysis method. Where the two methods have been previously employed on other Rimfire scandium prospects in the area, the lithium borate fusion method has typically increased individual scandium assay values by 5 – 10%.
As shown in Table 1, the most recent batch of lithium borate fusion XRF assaying returned an average increase in scandium assay values of 11% compared to the corresponding assay value obtained from the 4-acid digestion / ICP analysis method. There were also several individual samples that showed an increase in scandium grade of 25 – 50%.
The lithium borate fusion XRF results are important as they demonstrate that the actual scandium grades for Murga could be significantly higher than the original Murga drill intercepts (calculated using the 4-acid digestion / ICP analysis technique) previously reported by Rimfire (see Rimfire’s ASX Announcement dated 6 May 2024).
