Tivan acquires 100% of the Molyhil Project
Strategic acquisition of NT Major Project to enable high-value critical minerals precinct with common infrastructure and expedited development pathway
-
Tivan has executed a Binding Term Sheet with Investigator Resources Limited and Thor Energy Plc to acquire 100% of the Molyhil Tungsten-Molybdenum Project (“Project”) located 220km north-east of Alice Springs in the NT and adjacent to Tivan’s Sandover Fluorite Project.
-
The Project hosts a JORC Code (2012) Mineral Resource Estimate of 4.647 million tonnes at 0.26% WO3 (tungsten trioxide) and 0.09% Mo (molybdenum) (0.05% WO3 cut-off grade) for 12,100 tonnes of WO3 and 4,400 tonnes of molybdenum.
-
Tungsten and molybdenum are used in the defence, automotive, semiconductor and clean energy sectors; both are recognised on Critical Minerals Lists in all major jurisdictions and both are currently subject to export restrictions in China.
-
Small scale open pit mining of the Project’s tungsten and molybdenum deposit was undertaken during the 1970s; a Definitive Feasibility Study was published by Thor in August 2018; an Updated Mineral Resource Estimate was published by Investigator in May 2024.
-
As part of the acquisition, Tivan will also take assignment of all mineral rights held Investigator and Thor on tenements comprising the Company’s adjacent Sandover Fluorite Project.
-
Consideration for the acquisition totals $8.75 million, comprised of initial cash payments ($3.5 million) and deferred payments ($5.25 million) in cash or shares (with a value equivalent to 50% of deferred payments, at Tivan’s election). The deferred payments comprise three equal annual payments.
-
The acquisition, once completed, will provide Tivan with 100% ownership of an advanced, high-value critical minerals project that has unique development synergies with the Sandover Fluorite Project.
-
The acquisition enables Tivan to leverage existing relationships in central Australia, with the Northern Territory and Federal governments, and in Japan, in support of expedited project facilitation, offtake marketing, financing and development.
The Board of Tivan Limited (ASX: TVN) (“Tivan” or the “Company”) is pleased to announce that Tivan has signed a Binding Term Sheet with Fram Resources Pty Ltd (“Fram”), a subsidiary of ASX-listed Investigator Resources Limited (“Investigator”; ASX: IVR) and Molyhil Mining Pty Ltd (“Molyhil”), a subsidiary of ASX-listed Thor Energy Plc (“Thor”; ASX & AIM: THR, OTCQB: THORF) to acquire 100% of the Molyhil Tungsten-Molybdenum Project (“Project”).
The Project is located approximately 220km north-east of Alice Springs in the Northern Territory and hosts a JORC Code (2012) Measured, Indicated and Inferred Mineral Resource Estimate of 4.647 million tonnes at 0.26% WO3 (tungsten trioxide) and 0.09% Mo (molybdenum) (0.05% WO3 cut-off grade) for 12,100 tonnes of WO3 and 4,400 tonnes of molybdenum. The Molyhil Tungsten-Molybdenum Project also includes an operational production water bore, which is essential for any planned project development and operation.

Tungsten and molybdenum are listed on the Australian Government’s Critical Minerals List, highlighting their importance to Australia’s economy and national interests, and vulnerability to supply chain disruption. Both metals are also included on Japan’s list of designated “rare metals” for stockpiling and listed as critical or strategic minerals by a number of major economies including the US, the EU, China, the UK and Canada.
The strategic rationale for undertaking the acquisition is summarised as follows:
-
Addition of high-value critical minerals to Tivan’s project pipeline, diversifying the Company’s portfolio, whilst leveraging in-house project development capabilities.
-
Highly favourable commodity price outlook with a significant re-rating of tungsten and molybdenum prices underway, supporting project valuation and access to joint venture financing.
-
Existing JORC Code (2012) Mineral Resource Estimate to underpin technical and project studies, whilst mitigating geological risk and expediting the pathway to production.
-
Highly significant infrastructure, operational and logistical synergies with the Sandover Fluorite Project, enabling planning for a long-life critical minerals precinct in central Australia.
-
Opportunity to leverage established commercial relationships to support project facilitation, and to develop the Molyhil Project on an inclusive and respectful basis with the Traditional Owners and Central Land Council.
The Board of Tivan views the Molyhil Project as highly complementary to the Company’s mission of building a strategically important company across northern Australia. The Board believes that Tivan’s comparative advantages, especially in terms of in-house technical capabilities, governmental relationships, standing with Traditional Owners in central Australia, access to finance and project facilitation partnerships in Japan, along with proximity to the Sandover Fluorite Project, provide a unique foundation from which to develop the Molyhil Project for the benefits of shareholders.

Project Overview
The Molyhil Tungsten-Molybdenum Project is located approximately 220km north-east of Alice Springs in the Northern Territory in the Aileron Province. Access to the Project is off the Plenty Highway, which links to the Stuart Highway that runs from Darwin through Alice Springs to Port Augusta in South Australia.
The Molyhil deposit was first discovered in the 1970s and mined between 1978 and 1982. Various drill programs and studies were progressed between 2004 and 2024, supporting resource definition and estimation, and preliminary testwork. A Definitive Feasibility Study was published by Thor in August 2018. An Updated Mineral Resource Estimate was published by Investigator in May 2024 (see below for further details).
Mineralisation is hosted within two magnetite skarn bodies that overprint a Paleoproterozoic meta-carbonate units of the Deep Bore Metamorphics situated along the contact with the broad-scale intrusive I-Type Marshall Granite. The two lodes are referred to as the Northern Lode (also known as the “Yacht Club” Lode) and Southern Lode. Mineralisation outcrops as massive and disseminated scheelite (CaWO4), powellite (CaMoO4) and molybdenite (MoS2) bearing Magnetite-skarn within the historic open pit. The lodes are ellipsoidal, plunging steeply to the south and dipping steeply to the east. Mineralisation is open at depth for both lodes.
Existing ownership is under a farm-in and joint venture arrangement between the respective subsidiaries of Investigator (Fram) and Thor (Molyhil). Fram has the right to earn an 80% legal and beneficial interest in the Project, of which it has at the date of this announcement earned a 25% beneficial interest (with Molyhil holding the remaining 75% beneficial interest).[1]
Mineral Resource Estimate
In May 2024, Investigator prepared an updated Mineral Resource Estimate for the Project, undertaken as part of a verification program of the previous Mineral Resource Estimate update published by Thor in April 2021 and following the signing of the farm-in agreement between Thor and Investigator in November 2022 (refer to Investigator’s ASX announcement of 24 November 2022).
Investigator engaged independent resource consulting group H&S Consultants (“HSC”) to assist with the verification program and prepare the 2024 updated Mineral Resource Estimate.
The verification program involved additional RC and diamond drilling, including twinning of historic holes as well as confirmatory drilling in areas of lower drill density, supported by an extensive program of collection of specific gravity data from drill core facilitating bulk density modelling. As part of the program, HSC prepared a detailed quality assurance / quality control (“QAQC”) report, based on verifiable historic drilling data and Investigator’s new drilling data. The drilling data was used by HSC for the independent resource update.
Given the near surface expression and geometry of the mineralisation, the Mineral Resource Estimate was undertaken on the assumption that the deposit would be mined by way of a conventional open pit operation.

The updated JORC Code (2012) Molyhil Mineral Resource Estimate prepared by HSC is detailed in Table 1 below:
| WO3 | WO3 | Mo | Mo | Cu | Cu | ||
|---|---|---|---|---|---|---|---|
| Category | Tonnes | Grade % | Tonnes | Grade % | Tonnes | Grade % | Tonnes |
| Measured | 1,160,000 | 0.34 | 3,900 | 0.11 | 1,300 | 0.06 | 700 |
| Indicated | 1,664,000 | 0.27 | 4,600 | 0.10 | 1,600 | 0.05 | 800 |
| Inferred | 1,823,000 | 0.20 | 3,600 | 0.08 | 1,500 | 0.03 | 550 |

Table 1: Molyhil Project Mineral Resource Estimate (Investigator, May 2024)
Reported at a cut-off grade of 0.05% WO3 Tungsten and to 150mRL, based on an open pit mining scenario. Variability of summation may occur due to rounding to appropriate level of significant figures. A detailed summary of the technical parameters for the updated Mineral Resource Estimate is set out in Attachment A to this announcement.
Thor Mining Plc reported an updated and most recent Ore Reserve estimate statement in January 2018. Tivan has not undertaken sufficient work to validate the economic parameters underpinning the Ore Reserve statement, and, therefore out of prudence given the time elapsed since its release Tivan has elected not to report the Ore Reserve estimate statement in this announcement. Tivan intends to complete an independent and appropriate level of study to evaluate and report, if appropriate to do so, an Ore Reserve in accordance with the JORC Code (2012).
The main mineralised domains demonstrated sufficient continuity in both geology and grade to support the definition of a Mineral Resource, and the classifications applied under the JORC Code (2012). The drillhole database used by HSC, supported by QAQC reporting, comprised data from a total of 121 drill holes (89 RC and 32 diamond) for an aggregate total of 17,396m of drilling. Rotary Air Blast holes and other drilling prior to 2004 were used to inform the geological modelling, however assays from these sources were excluded from the updated resource due to insufficient QAQC support. Additionally, the data from three shafts and three underground crosscuts (total development length 198m) completed in 2005 was validated and used as part of the resource update. One new drilled diamond hole was designed to pass in close proximity to the northern cross-cut drive to assess grade continuity. The results verified the previously sampled and reported grades observed in the crosscut, and in addition to the thorough assessment of methodology and QAQC undertaken for the underground workings, HSC and Investigator considered this data to be of sufficient quality for inclusion in the updated resource estimate.
Tivan notes that the mineralisation envelopes modelled at Molyhill are considered open at depth and may therefore extend further than currently modelled. The significant change in tungsten and molybdenum prices observed since 2024 may also favourably influence resource modelling in the future.
A detailed summary of the technical parameters for the updated Mineral Resource Estimate is set out in Attachment A to this announcement.

Addition of high-value critical minerals at Tivan
Tungsten and molybdenum are considered high-value critical minerals, with current pricing in excess of US$50,000 per tonne (see charts below). The high-value of these products diversifies Tivan’s project pipeline and a provides a project pathway in central Australia that involves low transit volumes and low haulage costs.
Tungsten is steel-grey coloured and extremely hard metal, known as one of the strongest naturally occurring materials. It has the highest melting point among all elements, making it of high value in applications requiring high heat resistance. It is almost exclusively found in the form of chemical compounds with other elements. Tungsten is used for industrial tooling and machinery, aerospace and defence applications, electronics and semi-conductors, and niche high-density applications.
Molybdenum is a silvery-grey soft metal with a metallic lustre that has the sixth-highest melting point of any element. It is a naturally occurring metallic trace element found in natural minerals and recovered as a byproduct of copper and tungsten mining. Molybdenum is primarily used as an alloying agent, forming hard and stable carbides in alloys, enhancing strength, corrosion resistance and high-temperature stability in steel and superalloys. Molybdenum is used in the aerospace, automotive, industrial machinery, semiconductor and clean energy sectors.

The supply chains for these minerals are highly vulnerable to geopolitical disruptions due to concentrated production and processing. Recent Chinese export control measures on molybdenum and tungsten reflect a strategic shift to leverage critical mineral supply for industrial policy and national security objectives. This is driving Western policy responses, investing in supply diversification, domestic processing and strategic stockpiling.
Japan has maintained stockpiles of tungsten and molybdenum since the 1980s. The Japan Organization for Metals and Energy Security (JOGMEC) sold portions of Japan’s tungsten stockpile via a competitive bid process in 2005.[2]

Since February 2025, China has mandated export licenses for tungsten and molybdenum, issuing zero permits, effectively creating a trade embargo for export-ready forms. For molybdenum, China’s curbs have focused on certain high-purity molybdenum powders crucial for defence applications. China exported approximately 287 tonnes of the affected molybdenum powder in 2024 (roughly half of it to Japan).
China produces ~83% of global supply of tungsten and controls most downstream refining capacity. Export curbs and quota cuts have pushed prices to their highest levels in a decade (since 2013). China also produces 40–45% of the global molybdenum output and controls refined molybdenum powder exports critical for defence and high-tech sectors.

Infrastructure, Operational, and Logistical Synergies
As noted, part of the strategic rationale for the acquisition is the significant potential for infrastructure, operational and logistical synergies upon future development of both the Molyhil Tungsten-Molybdenum Project and the Sandover Fluorite Project. A centralised multi-commodity precinct model across the projects would enable common project infrastructure and generate material operational efficiencies and cost savings.
Potential exists to develop shared power, water, heat, compressed air and groundwater supply infrastructure. Accommodation camps and support facilities could be centralised between the two projects. A coordinated diesel/fuel distribution hub with satellite supply points could also be established.
The projects would benefit from a shared, single access road off the Plenty Highway and links to the Stuart Highway, and established logistics to export hubs in Darwin and southern ports. A single transport provider between the projects has the potential to unlock economies of scale in haulage and handling. Road upgrades and maintenance could be shared across the projects.
Potential also exists for development of centralised or co-located processing. Economies of scale in tailings and waste management could also be considered, reducing environmental impacts and capital and operating costs.

As part of the SF Acquisition, the parties agreed to the key terms of a “Mineral Sharing Agreement” allowing:
-
Sandover SPV1 Pty Ltd, a wholly owned subsidiary of Tivan, to explore for fluorite outside of the SF Tenements in an area along the northern boundary of EL22349 (which was retained by Fram and Molyhil).
-
Fram and Molyhil to explore for minerals other than fluorite on the SF Tenements (“Other Mineral Rights”).
Under the Binding Term Sheet, the Other Mineral Rights will be assigned to MNT SPV.
Consideration Payable
Total consideration payable by Tivan for the Acquisition totals $8.75 million, comprising staged payments as follows:
-
Non-Refundable Deposit : $500,000 cash payable within 5 business days of execution of the Binding Term Sheet.
-
Completion Payment : $3 million cash payable upon completion of the Acquisition.
-
Year 1 Payment : $1.75 million, payable as $875,000 in cash and $875,000 in cash or shares at Tivan’s election, one year from the date of execution of the Binding Term Sheet.

Other terms
Completion of the Acquisition is subject to and conditional on:
-
the payment of the Non-Refundable Deposit;
-
the lodgement of the instrument of transfer and grant of all necessary consents and approvals by the relevant Minister under the Mineral Titles Act 2010 (NT) to the transfer of the Molyhil Tenements to MNT SPV; and
-
obtaining the Central Land Council’s consent to the transfer of the Molyhil Tenements and assignment of a Mining Agreement to MNT SPV.
The above conditions must be satisfied by the date that is six months from the date of the Binding Term Sheet, or such other date as agreed by the parties (“Conditions Deadline Date”).
Fram and Molyhil have provided a non-exclusive licence to MNT SPV under the Binding Term Sheet to access the Molyhil Tenements for the purposes of undertaking non-ground disturbing works (including site inspections, surveys, mapping and environmental assessments) until the earlier of completion of the Acquisition or the Binding Term Sheet being terminated in accordance with its terms.
Fram and Molyhil have provided certain typical representations and warranties regarding the title and good standing of the Sale Assets under the Binding Term Sheet, which may be terminated by the parties in customary circumstances for agreements of this nature (including for breach or non-satisfaction of the conditions described above by the Conditions Deadline Date).
Project Planning & Next Steps
Over the past two years Tivan has developed a detailed and methodical model for evaluation and development planning for its resources projects, supported by strong in-house technical capability and external expert consultants across a range of fields. The robustness of this model is highlighted by the positive progression of the Speewah Fluorite Project in Western Australia.
Tivan’s project team has applied this model to initial development planning for the Molyhil Project. As a result, the Company will not rely on the outcomes of previous technical and economic studies completed for the Project, and reviewed as part of due diligence, but will instead undertake as an initial study phase a Pre-Feasibility Study (“PFS”) on the basis of the existing Mineral Resource estimate. This will ensure that the feasibility of the Project is assessed
==> picture [596 x 68] intentionally omitted <==
==> picture [596 x 127] intentionally omitted <==
consistent with Tivan’s rigorous technical and economic assessment framework and enable Tivan’s project team to assess and optimise coordination with the Sandover Fluorite Project.
In parallel Tivan will progress its own metallurgical testwork program for the Project in support of flowsheet development. This approach will enable Tivan to optimise target production from the Project, whilst taking into account the positive price developments in tungsten and molybdenum markets in recent years.
In taking this approach, Tivan will also ensure the Project is brought into alignment with changes in the regulatory landscape for mineral resources projects in the Northern Territory in recent years and ensure that project planning proceeds on an inclusive and respectful basis with the Traditional Owners and Native Title Holders.
Investor Briefing
Executive Chairman, Mr Grant Wilson, will host an Investor Briefing on Friday 19 September to introduce the Molyhil Project to shareholders and to discuss the development pathway ahead, including sequencing and synergies with the Sandover Fluorite Project. The Company will provide investor materials and dial-in details ahead of time.
Comment from Tivan Executive Chairman
Mr Grant Wilson commented:
“Tivan is the natural owner of the Molyhil Project. We have the capabilities, standing and determination required to lift the project out its prolonged orphan phase and into production in rapid time. The criticality of Molyhil is reflected in China’s recent export restrictions and the major shifts that are underway in favor of national stockpiling of select critical minerals. Tivan is operating at the frontier of these developments, with our strong governmental relationships in Australia and our Tier 1 project partners in Japan.
Molyhil also shapes a staging ground for Tivan in central Australia. As a previously disturbed site with established water infrastructure, our impact footprint would be materially reduced, aiding environmental approvals and respectful engagement with the Traditional Owners and Native Title Holders. At current commodity prices the first couple of years of mining would be extraordinarily profitable, enabling Tivan to optimally finance the development of an iconic critical minerals precinct in central Australia”.
This announcement has been approved by the Board of the Company.

Attachment A: Tivan Mineral Resource Estimate and Reporting Criteria
Tivan has signed a Binding Term Sheet with Investigator and Thor to acquire 100% of the Molyhil TungstenMolybdenum Project (“Molyhil Project”) located 220km north-east of Alice Springs in the NT and adjacent to Tivan’s Sandover Fluorite Project.
The mineral resource estimate for the Molyhil Tungsten-Molybdenum Project is being reported by Tivan in accordance with the 2012 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (“JORC Code”). The information in this announcement relating to exploration results, Mineral Resources and the reasonable prospects of eventual economic extraction of Mineral Resources is based on information compiled by Competent Persons facilitated by Investigator. Investigator previously released a Mineral Resource Estimate for the Molyhil Project on 28 May 2024 in conjunction with H&S Consultants Pty Ltd (“HSC”), updating the Molyhil Mineral Resource Estimate reported by Thor in 2021.
The following sections attached are provided in accordance with ASX listing Rule 5.8 and to ensure compliance with the JORC Code requirements for the reporting of the Molyhil Mineral Resource Estimate, and includes relevant Competent Person’s Statements. Tivan considers that the various technical and economic parameters detailed in Attachment A support a resource of which there is reasonable prospect of eventual economic extraction.
==> picture [596 x 68] intentionally omitted <==
Introduction
Investigator, in conjunction with HSC, devised a program of drilling aimed at Quality Assurance/Quality Control (QA/QC) verification of the pre-existing data via selective twinning of historic Reverse Circulation (RC) and Diamond Drill (DD) holes and confirmatory drilling in areas of lower drill density, supported by an extensive program of collection of specific gravity data from drill core supporting a greater focus on bulk density modelling. This drill program of 12 diamond holes (totalling 1,501 metres) was completed in December 2023. Significant intersections from this program are included in Appendix 4 of this release.
Data from historic drilling, that was able to be verified to a sufficient level of confidence, in addition to Investigator’s acquired data, was provided to HSC and supported by a detailed QA/QC report. This information was utilised by HSC to independently prepare the updated Molyhil MRE.
Updated Molyhil Mineral Resource Estimate
In preparation of the updated Molyhil MRE, Investigator is responsible for the accuracy and reliability of exploration data supplied to HSC and informing the MRE, whilst HSC takes responsibility for the Mineral Resource Estimation modelling and classification. The estimates are reported in accordance with the 2012 edition of the Australian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves (2012 JORC Code).
The Molyhil deposit is located in the Aileron Province, 230 km to the northeast of Alice Springs (Figure 1). Mineralisation occurs at the contact between altered Palaeoproterozoic meta-carbonate rocks of the Deep Bore Metamorphics and the broad-scale intrusive I-Type Marshall Granite.
The deposit is hosted within two magnetite skarn bodies that overprint the meta-carbonate units. These are referred to as the northern Yacht Club Lode and the Southern Lode (Figure 4). Mineralisation outcrops at surface within an historic open pit, mined in the 1970s & 1980s. The Lodes are ellipsoidal, plunging steeply to the south and dipping steeply to the east, with approximate dimensions of 55m x 60m x 250m (width x length x depth) for the Yacht Club Lode and 55m x 65m x 360m (width x length x depth) for the Southern Lode. Mineralisation is currently open at depth in both Lodes.
Mineralisation occurs as massive and disseminated scheelite (CaWO4), powellite (CaMoO4) and molybdenite (MoS2), predominantly within the skarn unit but also observed within calc-silicate and granite at margins of the host skarn.
HSC, following their due diligence review, recommended the use of Multiple Indicator Kriging (MIK) as a more appropriate method of estimation for modelling the heterogeonous style of the Molyhil tungsten and molybdenum mineralisation.
The tungsten and molybdenum resources were estimated by MIK method and are reported using E- type panel estimates above tungsten cut-off grades. The copper resource estimate has been reported utilising Ordinary Kriging (OK) methodology.
Estimates of resources are reported at a range of tungsten cut-off grades for open pit mining selectivity at practical block dimensions of 10m x 5m x 10m (length x width x depth).
Given the near surface nature and geometry of the Molyhil mineralisation, the MRE has been undertaken on the assumption that the deposit would be mined using open pit method and HSC has modelled and classified the resource accordingly.
Acknowledging the improved tungsten and molybdenum prices and the cut-off grades adopted in peer open-cut projects, coupled with the potential recovery improvements identified in the ore sorting study completed by Thor in 2021[1] , this updated MRE is reported at a 0.05% WO3 cut-off grade to the 150mRL level (a depth of 260m below surface). Investigator considers that these parameters support a resource of which there is reasonable prospect of eventual economic extraction. Thor’s Mineral Resource Estimate Update, utilising Mixed Support Kriging used a 0.07% WO3 cut-off grade to the 200mRL level (a depth of 210m) (as reported to the ASX on 8 April 2021).

Table 1: IVR’s updated Molyhil Mineral Resource Estimate, reported at a cut-off grade of 0.05% WO3 tungsten to 150mRL. Variability of summation may occur due to rounding to appropriate level of significant figures.
The result of the updated Molyhil MRE is an approximate 6% (or 261,000t) increase in global resource tonnes and a 4% decrease in global tungsten grade for an overall increase in global tungsten metal of 2% (or 289t) at a 0.05% WO3 cutoff compared to the previous 2021 MRE (Thor)[2] . The global grade of molybdenum and copper experienced slight decreases of 6% and 12% respectively, resulting in minor metal decreases of less than 1% molybdenum and 7% copper compared to the previous 2021 MRE.
The improvement in estimated global tonnage compared to the previous 2021 MRE is due to a combination of increased modelled in-situ rock density (resulting from Investigator’s extensive focus and work on densities), reporting to a lower cut-off grade of 0.05% WO3 (compared to 0.07% WO3) and reporting to a 260m depth, 50m below that used in the 2021 MRE. The slight decreases in molybdenum and copper contained metal resulted from minor reductions in grade following Investigator’s 2023 drilling.
There was a reduction in estimated tonnage within the Indicated Category where tonnage was converted to the higher confidence Measured Category. This was in addition to the adoption of a more constrained geometry of the skarn model in areas that lacked sufficient data to inform the MRE (particularly in the Yacht Club Lode).
Significantly, Investigator’s additional drilling and rigorous focus on capturing high quality data and QA/QC, resulted in the following increase of the Measured Category for the updated Molyhil MRE compared to the previous 2021 MRE (Thor):
- Tonnes increased from 464Kt to 1,056Kt (a 150% increase),
2 – Thor Energy PLC (THR) ASX – April 2021 Molyhil Project – Mineral Resource Estimate Updated.
-
Grade increased from 0.28% to 0.34% WO3 (a 21% increase),
-
Tungsten metal increased from 1,300t to 3,900t (a 200% increase).
Molybdenum and copper also recognised significant increases in the Measured Category with:
-
Molybdenum metal increase from 600t to 1,200t (a 110% increase),
-
Copper metal increase from 280t to 644t (a 147% increase).
A comparison with Thor’s 2021 MRE can be seen in Appendix 5.

Mineral Resource Classification
The updated Molyhil MRE for tungsten, molybdenum and copper has been classified as Measured, Indicated and Inferred by HSC. The main mineralised domains have demonstrated sufficient continuity in both geology and grade continuity to support the definition of a Mineral Resource, and the classifications applied under the 2012 JORC Code.
Estimates for mineralisation within the main mineralised Lodes are tested by drilling spaced nominally at 25m x 25m in the more well-defined areas of the deposit, reducing to 5m to 15m spacing within select parts of the skarn where Investigator drilled holes to twin older RC and DD holes to validate historic grades.
Confidence categories assigned to the estimates reflect qualitative panel criteria established by the resource consultant, including but not limited to, number of drillholes, number of samples, QA/QC (surveys, standards, duplicates etc.) within each individual panel of the block model.
Investigator has supplied HSC with sufficient information to support the utilisation of the reported cutoff grade, and lower depth of the MRE and HSC is satisfied with the assumptions and supportive information provided, including metal price improvements, improvements in potential processing options and taking into consideration improved confidence in the resource classification.
Updated Mineral Resource Additional Information
Domains used in Estimation
The deposit in hosted predominantly within two adjacent magnetite skarn bodies that overprint metacarbonate units of the Deep Bore metamorphics (1805 ± 7 million years ago, Ma), the skarn is proximal to Marshall granite intrusions (1780-1710 Ma) and outcrops at surface. Main logged units at the deposit are magnetite skarn, calc-silicate and granite, additional minor lithologies include aplite dykes, quartz veins and fluorite/barite veins.
A nominal cut-off grade of 10-15% Fe2O3 was used to define the MREs constraining wireframe of the two main skarn zones, the Yacht Club Lode and Southern Lode (Figure 4). The skarn wireframes were validated by both HSC and Investigator.
A plan view showing the distribution of drilling over the Molyhil deposit in relation to mineralisation constraining wireframes (Southern and Yacht Club Lodes) is shown in Figure 4 below.

Data used in Estimation
The compiled drill hole database supplied to HSC, supported by QA/QC reporting documentation, comprises information from 121 drill holes (89 reverse circulation and 32 diamond drill holes) for an aggregate total of 17,396m of drilling. Rotary Air Blast holes and other drilling prior to 2004 were used to inform the geological modelling however assays from these sources were excluded from the updated MRE due to insufficient QA/QC support.
Additionally, 3 shafts and 3 underground crosscuts for a total development length of 198m were completed in 2005 and verified geological and assay data from this source was utilised as part of this current MRE. These underground workings had been developed to resolve differences between costean bulk sampling, which supported historical mined grades, and historic RC drill hole grades.
One (1) newly drilled DD hole was designed to pass in close proximity to the northern cross-cut drive to assess grade continuity. The results verified the previously sampled and reported grades observed in the cross-cut, and in addition to the thorough assessment of methodology and QA/QC undertaken for the underground workings, HSC and Investigator considered this data to be of sufficient quality for inclusion into the updated MRE.
Drill holes within the main mineralised lodes are predominantly inclined RC and DD holes, drilled in a westerly orientation to intersect the north-south striking mineralised lodes. A small number of holes (4 in 2004, 1 in 2021 and 2 in 2019) were drilled in alternate orientations to assess the mineralisation distribution.
Twin hole comparison from the 2023 (Investigator) drill program showed broad lithological and grade continuity in all elements, however mineralisation was seen to extend beyond the historical skarn wireframe, likely due to the expanded sampling regime adopted by Investigator sampling 10m into the granite, compared with the historic sampling which was restricted to the mineralised skarn. Despite the good correlation with copper and molybdenum, tungsten displays greater variability, and was generally higher grade in Investigator’s recently drilled diamond holes.
All 2023 diamond core was HQ diameter from surface with half core sampling on one metre intervals undertaken. Samples were sent to a certified and NATA accredited commercial laboratory for multi-element analysis of a suite of elements including tungsten, molybdenum and copper (refer accompanying JORC 2012 Table 1 for detailed information). QA/QC protocols included duplicate sampling every 20[th] sample and inclusion of certified reference standards every 25[th] sample of the program.
A section view showing the resource estimate classification block model defining the two mineralised lodes, downhole geology for some of the 2023 drilling, and simplified geology in the background of image is shown in Figure 6 below.

Densities
Investigator identified that better data on rock density provided an opportunity to improve on previous resource estimations. Dry bulk density measurements for prior MREs were estimated utilising a linear (YonX) iron (Fe) regression calculation to assign density to each sample using specific gravity from a total of 69 RC Pycnometer samples analysed from 2 holes only (1 each from Yacht Club and Southern Lodes, spaced 90m apart).
Investigator had initially identified 17 historic diamond drillholes for which no previous specific gravity measurement data was obtained. Utilising this drill core, 1,462 Archimedes method (Density = Wd/(Wd-Ww) where Wd=dry weight, Ww=wet weight (for density where water is 1g/cm[3] )) were collected from all available drill core. An additional 1,841 specific gravity measurements were completed
from the newly drilled 2023 core, focusing on measuring as many pieces of core as possible throughout the mineralised skarn and calc-silcate units. This work provided a far larger dataset of 3,303 density measurements to utilize in modelling compared to the 69 previous density measurements.
For the updated MRE, dry bulk densities were assigned to each sample within the mineralised lode wireframes, allowing both the metals (WO3/Mo/Cu/Fe) and density to be modelled at the same search criteria. HSC recommended the use of an alternate regression method - Reduced Major Axis, which takes into account the ‘error’ in both variables (Fe and density) and is considered better suited for this type of deposit. The iron regression was used to populate density for each sample within the model but honoured actual field measurements where present.
A sensitivity analysis was undertaken, whereby the density model was run an additional four times using three alternate regression methods and using raw data alone. The results of all methods were similar, providing confidence in the model, which supported the uplift in tonnes in the Measured classification, where the majority of drilling and density data was available.

Market outlook
Tungsten is a strategically significant metal and a key input to industries vital to everyday life. The unique physical properties of tungsten (melting point/hardness/tensile strength) and lack of substitutes makes tungsten critical in industrial, oil & gas, mining and agricultural applications and as such is considered a strategic commodity in the USA, China, European Union and Australia. Rising supply concerns for defence, micro electronics and green energy end use continue to drive demand.
Current industry outlook for tungsten is strong due to growing demand but also as a result of high supply risk, with China accounting for over 83% of the world’s tungsten primary production. With growing demand for alternative sources of tungsten from the United States and allied countries, demand is anticipated to remain strong.

The global molybdenum market is also on a significant growth path, driven by rising demand in industries and regions worldwide. Renowned for its high-temperature stability, tensile strength, and corrosion resistance, molybdenum is crucial in producing high-strength steel alloys essential for construction, transportation, and energy sectors.
The rising demand for steel alloys in countries with developing economies as a result of urbanisation and the expansion of residential and commercial construction is expected to support molybdenum market growth. Additionally, opportunities in renewable energy and new applications for molybdenum are emerging.
The molybdenum price is historically volatile having reached more than US$90,000/tonne during February 2023 from a low of near US$17,000/tonne during August 2020. Current spot price sits at approximately US$69,000/tonne, having risen roughly 60% since January 2024.

| Sampling techniques • Nature and quality of sampling (e.g. cut channels, random chips, or specific special- ised industry standard measurement tools appropriate to the minerals under investiga- tion, such as down hole gamma sondes, or handheld XRF instruments, etc). These ex- amples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to en- sure sample representivity and the appropri- ate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisa- tion that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘RC drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be re- quired, such as where there is coarse gold |
Diamond Hole (DD) Drilling • Investigator Resources Ltd (IVR) 2023 DD program was undertaken with HQ2 size core drilled for all 12 holes completed in the program, totalling 1,501 metres. • Historic diamond drilling contained within this resource consists of mainly HQ core with small contribution of PQ, comprising 20 holes for 3,002.5 metres (195.6m PQ, 2,806.9 HQ) • IVR Diamond drilling was sampled at nominal 1m intervals down hole (88% at 1m for IVR drill- ing), or to geological boundaries, with “from” – “to” intervals recorded against sample number. • Historic sampling was reported as at nominal 1m intervals down hole (70% at 1m for historical drilling) or to geological boundaries resulting in some shorter and longer intervals, with only min- eralised skarn lithologies generally sampled. • IVR 2023 core was oriented on site by IVR geologists and a cut line applied to ensure consistent sampling of core from one side occurred. • All IVR 2023 diamond drill core samples were marked up onsite by geologists and field techni- cians and collected by cutting the core longitudinally in half using a diamond core saw. If an ori- entation line was present the core was cut to preserve the orientation line. If an orientation line was not present the core was marked with a cut line in order to provide the most representative uniform and unbiased down hole sample. • Historic orientation of core occurred sporadically with Tennant Creek Gold (TCG) orientating 5 geotechnical holes in 2005 (TMDH001-005). However, majority of previous diamond drilling is not orientated. • Historic core was longitudinally cut or split sampled and sent for analysis. • 2023 IVR duplicate pair analyses were undertaken by ¼ core paired interval samples every 20th sample in program. |

| that has inherent sampling problems. Unu- sual commodities or mineralisation types (e.g. submarine nodules) may warrant dis- closure of detailed information. |
• Historic (pre-IVR) core was generally ½ core sampled with exception of duplicate pair analyses which were ¼ core paired interval samples for drilling 2011 onwards. • Historic core drilled pre 2004 has no survey or Quality Assurance or Quality Control (QA/QC) in- formation and as such has not been incorporated in this or previous MRE’s. • All core samples were processed by laboratories using industry standard methods including crushing and pulverising prior to analysis. • Visual confirmation of mineralisation was undertaken utilising UV light for Tungsten, but not re- lied upon for resource estimation. • 2023 IVR program core was cut utilising an automatic core saw. Historically, core was either half split utilising a chisel or utilising a manual core saw. • Magnetic Susceptibility sampling utilised a KT10 meter that had been calibrated prior to the pro- gram. • Portable XRF was only used for mineral identification and not relied on for assay data. • Scintillometer readings were taken for the first 3 drillholes in the 2023 program to confirm that no radioactive hazards existed as part of the program. • Sample specific gravity analysis was by wet/dry Archimedes method of analysis using a cali- brated and certified scale. Within the mineralised skarn or calc-silicate zones measurements were recorded for all pieces of core greater than 10cm in size. In the unmineralised granite measurements were recorded every 2 – 3m. Samples had from and to measurements recorded. • IVR undertook SG measurements on all available historic core using the same equipment. SG generally was on ½ core for historic sampling. • Historic SG data collected by Thor Energy PLC (Thor) in one program was not utilised given ina- bility to confirm accurately the sample interval. Historic Reverse Circulation (RC) Drilling • RC drilling was reported in historic reports and database as sampled at nominal 1m intervals down hole (95% of RC is 1m). There was a small component of historical 2m, 3m, 4m and 5m composites outside of the mineralised material. • A total of 89 holes for 12,892.7 metres of RC were incorporated in the resource estimate. |
| Criteria and JORC Code explanation | Commentary | |
|---|---|---|
| • Sampling was undertaken using a stand-alone riffle splitter or a rotary cone splitter in programs with type of splitter identified in historic reports. Approximately 2-5kg of the original sample vol- ume was submitted to the laboratory for assay. • Riffle splitters were reported as visually inspected prior to drilling to confirm appropriate construc- tion and fitness for purpose. It was also reported that the splitter was blown clean between rods and when possible every metre within the ore zone. • Drill intervals had visual moisture content recorded i.e., Dry, Moist, Wet. • Records of sample volume are only reported from the 2011 RC program. • Duplicate sampling was only undertaken for the 2004, 2007 and 2011 RC drill programs. It was reported that subsequent re-sampling of 14 samples from the 2006 RC drilling for QA/QC pur- poses occurred during the 2007 program. Historic Underground Shaft and crosscut Bulk Sampling • Three shafts (2m x 1.2m) totalling 96m and three cross-cuts (2.1m x 1.2m) totalling 102m were sunk into the Southern Lode. The winzes and cross-cuts were all sampled at 2m intervals. • Each 2m advance created approximately 16 tonne of sample and was put through a crushing plant on site where material was crushed down to 12.7mm. • Samples for assay were generated by three methods; grab sample from stockpile, 4 x duplicate pairs collected by stopping the conveyor belt of the plant following crushing and sweeping crushed rock into a bucket, which was subsequently riffle split to create a 10kg sample, and fi- nally continuous sampling off belt (24 samples per cut), similarly into a bucket which was riffle split to create 10kg samples. • Crosscut sampling was used historically to compare RCsample gradesagainst bulk sample sample grades. This comparison resulted in the use of somewhat subjective “grade factoring” in a number of historical Molyhil Mineral Resource Estimates (MRE), however “grade factoring" was not implemented in the Thor 2021 MRE, nor in this current MRE. Other Aspects: |

| Drilling techniques • Drill type (e.g. core, RC, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc). |
Molyhil Tungsten Project Drilling Statistics: Aggregate total data used: • DD holes used as part of 2024 resource estimate was 32 for 4,503.5 metres and 1,934 samples. • RC holes used as part of resource estimate was 89 for 12,892.7 metres and 9,932 samples. • 3 x underground crosscuts and 3 x shafts used for a total of 198.1 metres and 100 samples. Drill data used in the updated resource estimate (includes components of historical resource and geotechnical drilling completed in 2004-2023): • Multiple Bulk sample, RC, DD programs have been undertaken at the Molyhil Tungsten Project with program documentation records retained in various levels of detail. • 2004-2011 RC drilling was completed using standard 5 ½ inch face sampling percussion ham- mers to variable depths and various dips and azimuths. • Drilling was conducted primarily on nominal 25m by 25m line spacing, reduced in some areas of the deposit to 12.5m by 12.5m. • Historic holes were generally angled at -60° towards the west (average of 252° azimuth) to opti- mally intersect the mineralised zones. • Diamond programs undertaken in 2004 and 2011 utilised wireline method with HQ bits. Core from both programs was orientated and logged structurally. The 2004 program utilised a spear to orientate the core immediatelyafter drillingand the 2011program employed a Reflex orientation |

| tool. No other historic programs of diamond drilling have records of core orientation. • During the 2011 Diamond program the top 3m was typically blade drilled and then cored to termi- nation, all other DD is recorded as cored from surface. • 2019 Thor diamond drilling utilised the wireline method with PQ coring from surface. The core was not orientated. • 2021 Thor diamond drilling utilised the wireline method with HQ coring from surface to bottom of hole, with the exception of one hole (21MH001) which changed to NQ2 from 20m to end of hole. The core was orientated. • 2023 IVR diamond drilling utilised the wireline method with HQ coring from surface. Orientation of core was done with use of a Reflex orientation tool. |

| Drill sample recovery • Method of recording and assessing core and chip sample recoveries and results as- sessed. • Measures taken to maximise sample recov- ery and ensure representative nature of the samples. • Whether a relationship exists between sam- ple recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
Diamond Hole Drilling IVR 2023 Program • 2023 DD recovery and geotechnical data were recorded during core logging for all holes in the company’s referential database. • DD recovery was measured against driller run returns for all holes. • Core runs were limited to smaller intervals in broken/fractured ground, with 3m runs only in fresh, competent rock. • 2023 DD mean recovery for all holes was 96.5%. • Recovery loss was primarily in the upper oxidised portion of the hole (0-18m) Historic Programs • 2004 DD, mean recovery was 99.7%. • 2011 DD, mean recovery was 98.5%. • 2019 DD, mean recovery was 97.8%. |
| Criteria and JORC Code explanation | Commentary | |
|---|---|---|
| • 2021 DD, mean recovery was 97.3%. Reverse Circulation Drilling • Percussion samples from RC programs between 2004 and 2011 were reported as visually checked for recovery and moisture content and the data recorded. The reported recovery figures available averaged 90% recovery. • Sample Quality for these programs were also recorded with table below showing 98% of samples being dry samples. Dry Moist Wet Total Count 3081 37 27 3145 Percent 98.0 1.2 0.9 100 • Sample weights from the 2011 RC program were analysed by IVR in conjunction with assay re- sults for corresponding intervals; this analysis showed no bias between variables. General: • Observed poor and variable recovery is recorded in the sampling database. Per the notes above, the recovery for both DD and RC is excellent, at or above industry standard. • Zones of poor DD recovery are flagged in the sampling database. • As part of the 2023 drill program, IVR did selective DD twinning versus a representative number of historical holes (DD and RC) to support recovery/grade observations and appropriateness of method. • Five (5) of the 2023 IVR holes were compared to nearby historical RC and DD drill holes from different sections of the deposit. Copper (Cu), Tungsten (W) and Molybdenum (Mo) were com- pared downhole. In general, these twin holes confirmed the presence of mineralisation, and some geological continuity. However, the twin holes highlight the heterogeneity and nuggety na- ture of the Mo and W mineralisation, with variable short distance grade continuity. Cu minerali- sation appears to have greater spatial continuity in comparison to that of Mo and W. Following completion of the drilling program further desktop review highlighted lack of downhole survey data for some RC holes that were twinned; this lack of spatial accuracy and known location of samples in 3d space makes comparison of grade continuity against these DD twins difficult. |
| Criteria and JORC Code explanation | Commentary |
|---|---|
| • Historically, within the 2004 program two pairs of twin holes were drilled comparing RC and DD methods (TMDH005 vs TMRC007 and TMDH004 vs TMRC019). Comparison of grades of equiv- alent intervals showed significant variation beyond the ascribed variance between the two types of drilling. Tennant Creek Gold (TCG) suggested that the variation is evidence of small-scale het- erogeneity of the mineralisation within the deposit, a feature not uncommon in skarn mineralisa- tion. However, IVR noted through re-analysis of these twinned holes that at the time of drilling and resource definition for the 2004 MRE, both diamond holes and RC holes were only single shot camera surveyed with only dip readings recorded. As such no azimuth data was recorded other than the planned collar azimuth. Thus, a 3D location of the samples is not possible and as a result, comparison of these holes as “twins” and Thor’s noted issue of RC vs DD grades (Conti- nental Resource Management, 2006) is considered inaccurate. Only hole TMRC007 was gyro- scopically surveyed in the later 2011 program. |

• In 2023, IVR’s holes were logged comprehensively and photographed on site. • Historic holes post 2004 were logged and photographed on site. • In 2023, IVR qualitatively logged lithology, colour, mineralogy, veining type and percentage, sul- phide content and percentage, description, marker horizons, weathering, texture, alteration, min- eralisation, and mineral percentage. • In 2023, IVR quantitatively logged magnetic susceptibility, specific gravity (DD only), geotech- nical parameters (DD only). • Historic quantitative logging included magnetic susceptibility and limited specific gravity in some of the DD which was not used by IVR or prior Thor resource estimations due to lack of QA/QC. Thor indicated that the quality of these specific gravity measurements was suspect and recom- mended the data was not used. Assessment by IVR identified that there was a greater percent- age of errors within the relatively small dataset additional to suspect interval sizes and agreed with Thor’s recommendation to exclude this dataset. • Portable XRF was utilised on an informal basis to identify zones of mineralisation and mineralogi- cal components to assist in lithological logging but not relied upon for reporting of analytical re- sults. • Historic underground developments were also geologically logged and mapped qualitatively and documented in reports. |

2023 IVR DD program • All HQ2 and DD core samples were collected by cutting core longitudinally in half using an auto- matic diamond core saw. • Core was marked during logging with a cut line under geological supervision, which served to preserve the orientation line if present. If an orientation line was not present the core was orien- tated as best as possible and marked in order to provide the most representative sample. • Sampling intervals for core were determined by the field geologist and marked on drill core and recorded in database. • All core where a field duplicate sample was taken (1 in 20 samples) was cut as quarter core lon- gitudinally. • Sample lengths were generally 1m and honoured geological boundaries. • All mineralised skarn and potentially mineralised calc silicate and a zone 10m either side of these units in granite were sampled continuously. A sample approximately every 10m within granite outside of these zones were collected for basic geochemistry. • Duplicate ¼ core samples (1 in 20) have been used to examine representivity and consistency. • Sample sizes are regarded as appropriate for the grain size of the material being sampled. Historic DD Programs • All PQ and HQ diamond drill core samples were collected by cutting core longitudinally in half us- ing a manual diamond core saw or via splitting with chisel and hammer (2004 Program). • TCG utilised duplicate analyses within their 2004 program. Thor has utilised a systematic stand- ard program since 2011. Confirmation of this system has been observed for all but 2019 pro- gram. • Certified Reference Material CRM data is not available for any program before 2011. • Data from the Thor 2011 program indicates that a sequence of every 25th sample was submitted as a standard, a different sequence of every 25th sample was inserted as a field duplicate and a third sequence of every 25th sample was inserted as a blank. This resulted in 3 samples in every 25 being a QA/QC sample (approximately 12% of all samples). |

| • 3-5kg samples was considered appropriate to correctly represent the W and Mo mineralisation based on: the style of mineralisation, the thickness and consistency of the intersections, the sam- pling methodology and assay value ranges for W and Mo. • Sample sizes are regarded as appropriate for the grain size of the material being sampled. Historic RC Programs • RC drilling was reported as sampled at nominal 1m intervals for those within prospective ore zones designated “Black rock Skarn”. Within barren country rock, spear composite samples were collected varying from 2m, 3m, 4m and 5m composites across different programs. • Sampling was undertaken either using a rig attached cyclone cone splitter to collect a 2-5kg rep- resentative samples to be submitted to the laboratory for assay. Wet samples were dried before dispatch. • The rig cyclone and splitter were reported as visually inspected prior to each program to confirm appropriate construction and fitness for purpose as well as blown clean in between rods and when possible, some programs specified every metre in the ore zone • Sampling method and quality of sample were recorded for all programs post 2004 excluding 2009. • Standard and duplicate sampling of RC programmes were undertaken in the same manner as historical DD sampling. • Sample sizes are regarded as appropriate for the grain size of the material being sampled. Historic Bulk Shaft/Crosscut Sampling • Each 2m advance created approximately 16 tonne of sample and was put through a crushing plant where material was crushed down to 12.7mm. • Three (3) sets of sample for assay were generated. o3 x Grab samples were collected from stockpiles of each advance pre-crush. o4 x 2 pairs of sample was collected from each advance following crushing and halting of conveyor, where belt was swept into calico. o24 x 20L bucket of crushed material was collected from each advance at end of conveyor prior to riffle splitting. A resultant 10kgsample was sent for assay. |

| • Sample sizes were regarded as appropriate for the grain size of the material being sampled. Duplicates: • 2011 program had a total of 68 field duplicates submitted for Cu, Fe, Mo and W. An analysis of Cu was not completed as this element was not included in the 2012 resource estimate. Field du- plicate QA/QC results show the 2011 drill data can be considered acceptable for further use. A relatively greater assay variation is observed for Mo and W when compared to Fe as would be geologically expected due to the heterogenous and nuggety nature of mineralisation. Laboratory sample preparation • Subsampling techniques are undertaken in line with standard operating practices to ensure no bias. • QA checks of the laboratory included re-split and analysis of a selection of samples from coarse reject material and pulp reject material to determine if bias at laboratory was present. This was undertaken during the 2004, 2006, 2007, 2011, 2021 and 2023 programs. • The nature, quality and appropriateness of the sampling technique is considered appropriate for the grainsize and type of mineralisation and confidence level being attributed to the results pre- sented. |

2023 IVR Program • ALS Laboratories (ALS) (Perth), a certified and NATA accredited commercial laboratory, was used for all assays from 2023 drilling. • Samples were analysed using methods “ME-MS61” and “ME-MS85”. • MeMs61 samples were prepared to a 0.25g prepared sample subjected to a 4-acid total digest with perchloric, nitric, hydrofluoric and hydrochloric acids and analysed by ICP-AES and ICP-MS for 48 elements including Mo, Cu and Fe. • Over-range samples for MeMs61 (>1% Mo, >1% Cu) were re-assayed using methods “Cu- OG62” and “Mo-OG62” (Cu and Mo). A 0.4g prepared sample was subjected to a 4-acid total di- gest with ICP-AES finish with an upper detection limit of 50% Cu and 10% Mo. |

• Fe results (>50%) were re-assayed by method Fe-ICP89 using a sodium peroxide fusion with ICP-AES finish to 70% Fe. • ME-MS85 samples were prepared with a lithium borate fusion flux and analysed by ICP-MS. This method was used exclusively to analyse for W after discussion with ALS Laboratories. • Over range samples for W (>1%) were analysed by MEMS85h, ore grade W by Fusion/ICPMS, to an upper detection limit of 5%. • Over range samples for W (>5%) were analysed by ME-XRF15b involving a 12:22 lithium metaborate-lithium tetraborate flux containing 20% NaNO3 with an XRF finish. Detection limits for W are up to 15.9%. • Umpire check analysis with Bureau Veritas (an alternate NATA accredited laboratory) for a sub- set of approximately 58 assay pulps from the 2023 drilling, with varying W and Mo grades, were undertaken to confirm the level of accuracy reported by ALS laboratories. Results for this work from Bureau Veritas have not been received at the time of this release. • ALS umpire check analysis of historic Bureau Veritas analyses for the 2011 diamond drill pro- gram was undertaken in 2024. Results show a strong positive correlation between original and re-submitted samples (R2> 0.98 for all elements W, Mo, Cu & Fe). Historic programs • Previous programs have utilised a multitude of accredited commercial labs over the course of the project’s lifetime with samples sent for preparation (crushing and pulverising) and analysed using the XRF method at various laboratories including ALS Perth, Amdel Adelaide and Genalysis Perth. • Details of assay laboratory and method assayed are present in the Thor database handed over to IVR prior to the program of work. • Additional detail on historic assay method can be found in the prior Thor MRE release to the ASX dated 8th April, 2021 (ASX,THR 2021). • Umpire check analyses 6 samples was undertaken by THR at Ultra Trace (UT) from the 2004 program and compared against ALS results.

| behaviour is not as noticeable for Mo. This behaviour was concluded to be reflective the nuggety nature of the ore. • A total of 41 pulps originally analysed by ALS were sent to Ultra Trace Pty Ltd, Canning Vale (Ul- traTrace) for check analyses. UltraTrace carried out the analyses by X-Ray Fluorescence Spec- trometry (XRF) on a fused glass bead. Fourteen of the pulps were from the 2006 drill pro- gramme and the other 27 from the 2007 programme. • A total of 26 pulps from the 2007 programme originally analysed by Genalysis were also sent to UltraTrace for check analyses. • Prior to 2011 drilling program Certifiable Reference materials and blank quality control samples were not utilised. • 2011: A program of field duplicate sampling was undertaken by Thor to compare the original samples with a field duplicate resample. Field duplicates were collected every 25th sample where the sample bag number ended on #15, #40, #65 or #90. The RC duplicates were collected using a riffle splitter and were taken at the time of drilling. Quarter core duplicates were taken from diamond core during core cutting. A total of 68 field duplicates were submitted for analysis. Field duplicate QA/QC results show results are within acceptable limits for iron, however some widely scattered field duplicate results for molybdenum, tungsten and copper were observed. A relatively greater assay variation is observed for Mo, W and Cu when compared to Fe as would be geologically expected due to the nuggety nature of the mineralisation resulting in high grade variability. • 2011: Certified XRF standards were inserted every 25th sample where the sample bag number ended on #05, #30, #55 or #80. The standards were provided by Geostats Pty Ltd as pulverised material sealed within air-tight plastic packets. Separate standards were used for molybdenum and tungsten as a combined molybdenum and tungsten standard was not available. Most of the results were within the upper and lower warning limits. • 2011: Blank Quality Control standards were uncertified and are sourced from an adjacent 2009 RC hole. The drill cuttings were collected from the barren hanging-wall zone and are geologically similar to drill samples submitted for assay. RC assays have confirmed the blanks contain only very low levels of molybdenum or tungsten grade. QA/QC Summary • Records of QA/QC techniques undertaken during IVR’s 2023 drill program in addition to historic QA/QC techniques undertaken by Thor and others and provided by Thor are retained by IVR. |

| • Certified reference standards including blanks, were randomly selected and inserted into the sampling sequence (1 in 25 samples). Standards were designed to validate laboratory accuracy and ranged from low grade to high grade material. Review of standards indicated that they re- ported within expected limits with no evidence of bias. This practice was implemented from the 2011 program onwards. • Detailed data from the 2011 program indicates that a sequence of every 25th sample was sub- mitted as a standard, a different sequence of every 25th sample was inserted as a field duplicate and a third sequence of every 25th sample was inserted as a blank. This resulted in 3 samples in every 25 being a QA/QC sample (approximately 12% of all samples). • Field duplicate samples for the IVR 2023 program were routinely taken on every 20thsample. Duplicate sample results showed no bias relative to their original sample. • A detailed QA/QC report was generated for the 2024 MRE by IVR, covering all aspects of current IVR and historical drilling programs, and bulk sampling activities over the course of the • project’s lifetime. This document includes key analysis of all data and procedures and was sup- plied to the independent resource consultant. • No significant analytical biases have been detected in the results presented. |

| Verification of sampling and assaying • The verification of significant intersections by either independent or alternative com- pany personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. |
• Significant intersections are calculated in the company’s cloud hosted and remotely managed database (Datashed5). These significant intersections were verified by Investigator personnel visually and utilising Micromine drill hole validation. Intersections are calculated using IVR speci- fied thresholds and allow for 1m internal dilution. • Additional 3rdparty validation of significant intersections was completed by an independent re- source consultant. • Five (5) drill holes at Molyhil were twinned during the 2023 program, to assess representivity and short-range spatial variability. This included DD/DD twinning and DD/RC. • Five (5) of the 2023 IVR holes were compared to nearby historical RC and DD holes from differ- ent sections of the deposit. Three (3) analytes of Cu, W and Mo were compared downhole. In general, these twin holes confirmed the presence of mineralisation, and some geological continu- ity. However, the twin holes highlight the heterogeneity and nuggety nature of the Mo and W min- eralisation, with variable short distance grade continuity. Cu mineralisation appears to have greater spatial continuity in comparison to the nuggety nature of Mo and W. Following comple- tion of the drilling program further desktopreview highlighted lack of downhole surveydata for |
| Criteria and JORC Code explanation | Commentary |
|---|---|
| some RC holes that were twinned. This lack of spatial accuracy and known location of drillholes makes comparison of grade continuity against these DD twins difficult. • Historically, within the 2004 program two pairs of twin holes were drilled comparing RC and DD methods (TMDH005 vs TMRC007 and TMDH004 vs TMRC019). Comparison of grades of equiv- alent intervals showed significant variation beyond the ascribed variance between the two types of drilling. TCG suggested that the variation is evidence of small-scale heterogeneity of the min- eralisation within the deposit, a feature not uncommon in skarn mineralisation. However, IVR noted through re-analysis of these twinned holes that at the time of drilling and resource defini- tion for the 2004 MRE, both diamond holes and RC holes were only single shot camera surveyed with only dip readings recorded. As such no azimuth data was recorded other than the planned collar azimuth. As a result, comparison of these holes as “twins” and Thor’s noted issue of RC vs DD grades (CRM, 2006) is considered inaccurate. Only hole, TMRC007, was gyroscopically sur- veyed in the later 2011 program. • Following the the 2004 DD and RC drilling program and the identification of potentially poor correlation of W grades across drill types and when compared to historical mining grades, a bulk sampling program in 3 costeans was undertaken over the Southern Lode to compare against drill grades of nearby RC holes. Results from the costeans were compared against the neighboring RC holes drilled in the 2004 program, showing a significant difference in grade between the costean bulk samples and RC estimated grades informing the 2004 CRM block model. IVR is of the opinion this difference is a reflection of the overall displacement of the drillhole compared to the surficial expression of the costean, with sample points not in a comparable location. In addition, the known heterogenity of the deposit is possible cause for variation in sample grades over distance. • Further bulk sampling was undertaken in 2005 by Thor in an attempt to resolve the differences between the previous costean bulk sampling and RC grades. A total of three (3) vertical shafts (96m) and subordinate crosscuts (102m) were sunk into the Southern Lode. Samples were col- lected in two metre advances with each sample weighing approximately 12 tonnes. Results from this bulk sampling program agreed with previous costean sampling showing poor correlation be- tween RC drill grade and bulk sample grade, indicating RC was potentially under reporting grade. • Subsequent MRE’s up to 2019 applied an adjustment factor up to +114% for Mo and +144% for W for RC grades to account for differentiation of sample types. It was interpreted that the coarse- grained, brittle and heterogeneous nature of the mineralisation, as confirmed by underground mapping in 2005, could result in a likely sample bias for the RC assays of W and Mo compared to the interpreted more representative underground bulk and diamond core samples. However, |
| Criteria and JORC Code explanation | Commentary | |

| this practice was discontinued in the 2021 MRE due to issues seen in locality comparisons of sample types. No factoring has been considered of utilised in this current MRE. IVR Data • Primary data was directly captured into LogChief field software and synchronised into an online, secure cloud hosted and externally managed database (Datashed5). • Logchief field data capture software has unique user ID and password requirements. • All assay data undergoes automated importation into Datashed5 along with QA/QC check analy- sis by batch (eg sample number match, standard and duplicate analysis, pulverisation checks etc) Failures of QA/QC analysis causes importation to be halted until IVR have undertaken in- spection and verification of data, and approved import with details. • All assay data is cross validated using Micromine drill hole validation checks including interval integrity checks. Further integrity checking was undertaken by the independent resource con- sultant on receipt of data. • Results reported as percent are left in this format within the new database. Below detection re- sults reported with a “<” sign are converted to “-“ as part of importation. • Where an over range re-assay is returned, the result is transferred into the database with the method of analysis identified against each sample number with such over range results. Over- range analytical methods are prioritised to prevent reporting errors. • Laboratory assay data is auto imported to mapped element fields from laboratory supplied ex- ports within Datashed5 for all 2023 data. Importation requires preset QA/QC hurdles to be cleared relating to standard and duplicate data, with review and acceptance of any failed batches by a competent senior geologist of Investigator Resources. Failed hurdle batches require com- mentary as to why the batch is to be accepted, else query to lab and re-assay. • All historic data was supplied to IVR by Thor and has undergone significant review and QA/QC checks. For example, it was identified that Cu was imported incorrectly for the two 2019 dia- mond holes and Cu and Fe for the 2005 shafts and cross-cuts. The issue was Cu% being im- ported as Cu2O3% and Fe2O3% being imported as Fe%. This was corrected in Investigator’s da- tabase prior to resource estimation. |

• DD, RC Holes and Shaft locations were initially field located utilising handheld GPS (accuracy of approximately +/-4m) and ortho-imagery. These were subsequently picked up using a Differen- tial GPS with typical accuracy of +/- 10cm. • All accessible drill hole collars, underground shafts and starting azimuths and downhole devia- tions were accurately re-surveyed by Direct Systems surveyors in 2011. Confirmation of these recordings were subsequently undertaken by IVR at the end of the 2023 drill program, utilising a Differential GPS for collar locations (hired through Ultimate Positioning), with typical accuracy of +/- 10cm, and utilising a reflex gyro (provided by United Drilling) – Collar shot only. Locations of collars were accurate to within 2m with only 2019 holes showing variance up to 5m from rec- orded collar location. • Survey method for all drill holes is recorded in the company’s referential database. • Topographic control uses a high resolution DTM generated by drone survey utilising an IVR owned and operated drone, with 8cm spatial resolution. This DTM was resolved using known points picked up by handheld GPS. Subsequent differential GPS pick-ups also provide topo- graphic control to 3cm resolution. Down hole surveys • IVR 2023 DD holes were surveyed at start of hole within the collar (6-9m), then every 30m down hole. This allow tracking of hole whilst it was being drilled. Additionally, upon completion, each hole was surveyed continuously in and out of the hole. A reflex gyroscope survey tool was uti- lised by United Drilling Services for this work, due to the highly magnetic nature of the mineral- ised zone. • Hole setup involved multiple gyroscopic mast shots to ensure lineup was accurate to planned az- imuth before commencement of drilling to counter effects of magnetite in skarns. • Survey results, depth and survey tool are recorded for each hole in Investigator’s drilling data- base. Hole surveys were checked by geologists for potential errors or setup errors. Suspect surveys were flagged in the database and omitted where reasonable evidence was present to do so. • Historical RC and DD holes typically had a survey completed at 30m intervals. However, pre- 2011 programs utilised single shot reflex tool which is heavily affected by the magnetic nature of the Molyhil Ore body. As such only dip readings were recorded with absolute certainty of accu- racy. |

| and collecting scoops from each determined composited interval. Composites varied from 2m up to 5m. upon recognition of mineralised intervals within composited samples. 1m samples were then collected and assayed. • Two 1m samples from the 2023 IVR drill program were mixed/composited during sample prepa- ration by the laboratory. IVR were notified immediately about the incident. Under instructions from IVR, the analysis was continued as a 2m composite sample. The initial 1m samples were reported as destroyed. |

| Orientation of data in relation to geological structure • Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orien- tation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
• The majority of the known mineralisation is interpreted to occur in both primary and alteration controlled vertical to sub-vertical layers. The drilling orientations are considered appropriate to test these orientations. • Drill holes are orientated predominantly to an azimuth of 252° and drilled at an angle of -60° to the west, which is approximately perpendicular to the orientation of the mineralised zones. • Inclinations for drillholes from 2011-2014 have, in the majority been at -60°, however there are several holes drilled at -55° earlier drilling programs. Specific holes have had variable azimuths and declinations to suit the target objective of each drillhole. |

2023 Diamond Drilling • IVR core was secured on site in core trays, strapped, then transported to a secure warehouse (Emmerson Resources processing facility in Tennant Creek) for contract cutting/sampling. Drill core was sampled under supervision of an Investigator geologist and Field technician at the com- mencement of sampling to satisfy IVR standard procedural requirements. • All core is photographed prior to dispatch from site. • Pallets of core have lids and are metal strapped at site to ensure no loss or tampering or damage to core whilst in transit to the contract cutting and sampling warehouse. • Core sampling is undertaken under contract by experienced technicians with sampling intervals marked up and defined by Investigator geologists in advance. Sample intervals and sample number designations were written on core and core trays on site prior to transport. Sampling/cut sheets were supplied to core cutting contractors independent of core delivery. |

| Geology • Deposit type, geological setting and style of mineralisation. |
•The Molyhil Tungsten Project is a W-Mo deposit that is hosted predominantly within a Fe enriched altered magnetite skarn that overprints meta-carbonate units of the Deep Bore metamorphic se- quence at the contact of a large intrusion of peraluminous monzogranite, Marshall granite. •The Molyhil area is amongst a range of west-northwest trending 10-100km crustal scale shear zones, including the Delny Shear zone, which have caused widespread structural adjustment of geology in the area. A number of smaller faults are believed to have been activated and reac- tivated over the long tectno-thermal cycle of these regional shear and fault zones from 1.79 -1.70 Ga. •Molyhil is comprised of two north-south trending, magnetite altered, mineralised zones that plunge 65° to the south and dip steeply to the east. The larger Southern Lode (approx. 55m x 65m x 360m (width x length x depth), to a vertical depth of approx. 320m) and smaller Yacht Club Lode (approx. 55m x 60m x 250m (width x length x depth), to a vertical depth of 200m) are sepa- rated by foliated, compositionally layered paragneiss and meta-carbonate rocks of the Deep Bore Metamorphic sequence. •This sequence has been intruded by a large volume of peraluminous granite (Marshall) with multi- ple pulses of intrusion sometimes crosscutting mineralisation. A range of interpreted post mineral- isation aplitic dykes also crosscut across older intrusions and the magnetite skarn body. The |

| Georgina basin uncomformably overlays and is faulted against the Deep Bore Domain in the area of Molyhil. •The deposit comprises of massive and disseminated Scheelite (CaWO4), Powellite (CaMoO4), Molybdenite (MoS2) together with magnetite. Mineralisation is layer parallel and occurs primarily within horizons of the cackleberry meta-carbonate that has been altered to diopside skarn at con- tacts with the Marshall Granite. •The mineralised meta-carbonate exoskarn alteration comprises predominantly of garnet-scapo- lite-diopside-hedenbergite whilst the endo skarn granite consists of microcline-actinolite-diopside- quartz-calcite-biotite. •The deposit has a number of crosscutting structures that have offset some mineralisation includ- ing the Yacht Club Fault, a dextral fault trending east-southeast. This fault offsets and slightly ro- tates the Yacht club and southern orebodies which are believed to be fault displaced sections of a singular mineralised body. This faulting is typically associated with possible Neoproterozoic stage carbonate-fluorite-barite veining that crosscuts mineralisation and granite alike. |

•IVR and Thor have developed a comprehensive geological interpretation of the Molyhil deposit based on geological logging and chemical assays. IVR personnel, and their predecessors Thor, have a good understanding of the geology of the deposit. This is, in part, reflected in the wireframe models of the two skarn bodies that they had initially prepared (later modified by HSC to incorporate new drilling), which form a solid framework for Mineral Resource estimation. •IVR’s interpretation of the deposit’s geological setting, which is primarily based on logging and as- saying of diamond drill holes and review of all historic data, is of sufficiently high confidence to in- form the MRE. •The Molyhil deposit consists of two adjacent outcropping iron rich skarn bodies, enclosed in gran- ite, that contain powellite, scheelite and molybdenite mineralisation. Both skarn bodies strike ap- proximately north south and dip steeply to the east. The bodies are arranged in an en-echelon manner, the northeast body being named the Yacht Club Lode and the southwest body the Southern Lode. |

| grade and geology. • The effect, if any, of alternative interpreta- tions on Mineral Resource estimation. |
•IVR has identified that historic focus and interpreted source of mineralisation had been associated with “Black Rock Skarn” lithology, suggesting magnetite alteration is associated with tungsten mineralisation. Observations whilst logging and undertaking density checks identified mineralisa- tion associated with areas of little to no magnetite alteration. A historic reference to a structure is interpreted by IVR to potentially act as a later focus to magnetite alteration, suggesting potential for emplacement after W mineralisation. •The bedrock is exposed within the open pit environment particularly the “Southern Lode” which has had historic mining. •The continuity of the two main mineralised lodes is clearly observed by relevant W, Mo and Cu grades within the drill holes. The close spaced drilling and historic trench and underground sam- pling, in addition to open pit exposures, suggest the current interpretation is robust. The nature of the lodes would indicate that alternate interpretations would have little impact on the overall MRE. •Mineralisation is coarse-grained and its distribution is irregular. Two broad lithological variations are present within each of the two main skarns. o“Black rock skarn”: Mineralised (which, historically, was selectively mined on the basis of its colour) a calc-silicate containing a high proportion of magnetite, pyrite, and iron-rich minerals such as andradite-garnet, actinolite, and ferro-amphibole. This unit is irregularly mineralised with scheelite, molybdenite, and chalcopyrite. The mineralisation is, in general, both coarse- grained and heterogeneous. Decimetre wide bands rich in molybdenite and/or scheelite are separated by metre scale bands of barren/low grade black rock skarn. oUnmineralised (little to no Fe/W/Mo/Cu) skarn: a pale green calc-silicate rock containing di- opsidic pyroxene and garnet. • A nominal cut-off grade of 10-15% Fe2O3was used to define boundaries of the two main skarn zones, Yacht Club Lode and Southern Lode, and one much smaller one, Yacht Club Lower, This Fe2O3grade range was determined from analysis of log probability plots of all samples at the de- posit and also adopted, in large part, from Thor’s initial work. The Fe2O3cut-off was initially used to define the two skarn’s mineralised zones in a gross sense and create the initial 3D wireframes. From there, the 3D skarn wireframes were manipulated by HSC, and verified by IVR, to reflect the IVR 2023 drilling and to include any significant W/Mo/Cu mineralisation that was as- sociated with lower Fe2O3. This manipulation by HSC was done by adding additional points, snapped to drill hole intercepts, which may include more W/Mo/Cu intercepts that were not nec- essarily associated with higher Fe2O3or to exclude non-mineralised (W/Mo/Cu) intercepts within in otherwise higher Fe2O3zones. In some places, this may have increased or decreased the ini- tial width of the skarn as interpreted byThor/IVR. Thesepoints where then used to create 3D |

| surfaces of footwall and hanging wall for each skarn, which were then joined together to create a 3D wireframe volumes for the two mineralised skarns. •These 3D wireframe volumes, representing the two main mineralised skarns (and one very small skarn), were used to guide and control the mineral resource estimation procedures for W/Mo/Cu/Fe and density. •There is some scope for alternative geological interpretations of the deposit, principally in the in- terpretation of possible higher grade sub-zones within the two main skarns and also possible down dip extension(s). However, at this time any geological modelling of sub-zones are quite diffi- cult to define given the current drillhole spacing and the irregularity of the mineralised lithology units. While this could affect estimates locally, it appears unlikely to have a significant impact on the global MRE. And vertical/down dip extensions to the mineralised skarns would be beyond that of the current preliminary project economics. Drill density at depth is insufficient to determine if potential remains for strike extension of the two skarn lodes. |

Drill hole spacing is nominally 25x25m in the better drilled areas of the deposit reducing to 5-15m spacing within select parts of the skarns where IVR holes twinned some of the original older RC drillholes. So, the parent block size is about half that of the overall nominal hole spacing, which is considered appropriate for MIK (multiple indicator kriging) estimation. The same block size was used for ordinary kriging (OK) es- timates, •WO3and Mo were estimated by multiple indicator kriging (MIK), using the e-type or average block grade at the scale of the panels, making the panel block size the selective mining unit (SMU). •All other attributes were estimated by OK, including Fe, Cu and DBD. OK was considered appro- priate because the coefficients of variation (CV=SD/mean) are generally low to moderate, and the grades and density are reasonably well structured spatially. MIK was chosen for W and Mo pri- marily because the CV is higher and due to the known ‘nuggety’ and coarse grain nature of the W and Mo mineralisation. •No assumptions were made regarding the recovery of any by-products. •MIK estimates were generated using GS3 software, while OK estimates were produced in Micro- mine software. •Each of the two main skarns, and the small one as well, were estimated separately. Each skarn had its own set of indicator (WO3and Mo) and metal variograms (Fe, Cu, DBD) used by the MIK and OK routines. •A five pass search strategy in GS3 was used for the MIK grade estimates: • 5 x 20 x 20m search, 16-48 samples, minimum of 4 octants informed • 7.5 x 30 x 30m search, 16-48 samples, minimum of 4 octants informed • 20 x 80 x 80m search, 12-48 samples, minimum of 2 octants informed • 30 x 120 x 120m search, 12-48 samples, minimum of 2 octants informed • 30 x 120 x 120m search, 6-48 samples, minimum of 1 octants informed |

• The last three passes were combined to form a final ‘pass 3’ for the MIK • For the Yacht Club Skarn there were 79 blocks within the wireframe, at the furthest down-dip extent, that had not been estimated during the MIK search passes. IVL wished to have these estimated so that a closer volume comparison could be done versus the Thor model. So these blocks were assigned the average grade of the 3 closest holes (TMRC024/031/060) for WO3 and Mo. •A four pass search strategy in Micromine was used for the OK grade and DBD estimates: • 5x20x20m search, min 4 holes, min 1 sample per hole, max 12 samples • 10x40x40m search, min 2 holes, min 1 sample per hole, max 12 samples • 20x100x100m search, min 1 hole, min 1 sample per hole, max 12 samples • 40x160x160m search, min 1 hole, min 1 sample per hole, max 12 samples • The last pass 4 was an additional larger pass was used for Cu and DBD, both with fewer data, to ensure estimates in all blocks had an estimated value •Search radii for the MIK and OK estimates where the same, but the number of required data differ slightly because of differences between GS3 (sample count specific, octants) and Micromine (sample and hole count specific, quadrants) setups. •For the MIK estimates, the maximum extrapolation distance will be somewhat less than the maxi- mum search radius due to octant constraints requiring at least 4 drill holes. Maximum extrapola- tion distance is around 300m. •All elements have been estimated independently for each domain. •An assumption of the correlation of Fe versus density has been used, and demonstrated as a valid strong correlation, via statistical and graphical analysis. In this way a modelled density value (linear regression, RMA) was assigned to each sample that was assayed for Fe so that density could be estimated in more detail into the block model. Note that not all samples that had W and Mo assays had a Fe assay. No other element pairings appear to show good correlation; they are either poor or no correlation at all. Also, other elements besides Fe, so no correlation with density, eg W v density or Mo v density. •It is assumed that a W/Mo/Cu concentrate will be produced. Given the nuggety nature of the W and Mo mineralisation, it is also assumed that an ore sorting process/circuit, such as a TOMRA style sorter, would be part of the mining process. |

| •No deleterious elements have been estimated. Being a magnetite skarn, the sulphur content is, overall, quite low. However, some higher sulphur grades are seen in the assayed samples. Inves- tigation for the characterisation of acid mine drainage will be undertaken as part of planned/ongo- ing metallurgical and ore sorting studies. •DBD was estimated directly into the model from the drill hole samples, using a similar methodol- ogy to the other elements. DBD data for each sample, if it was assayed for Fe, was derived per the relationship of Fe v DBD, as described above. •The geological interpretation controls the MRE through the use of the 3D wireframes for the two main skarn (Yacht Club and Southern) and one much smaller skarn wireframe (Yacht Club Lower). The wireframes were used as hard boundaries during estimation. •MIK is designed (in this case, for WO3and Mo) to overcome the need, or at least strongly miti- gate, the need for grade top cutting. This is done through the use of grade indicators and indicator variograms. However, the moderate CVs for WO3and Mo and a review of the conditional statistics for the top indicator class for both skarns, and the known nuggety nature of the WO3and Mo min- eralisation within the skarns, resulted in HSC deciding to use the average of the mean and the median for the top indicator class. •The Fe/Cu and DBD grade distributions are not strongly skewed, and have a low CV; no grade cutting was used. •The new model was validated in a number of ways – visual comparison of block and drill hole grades, statistical analysis, examination of grade-tonnage data, and comparison with previous models. All the validation checks indicate that the grade estimates are reasonable when com- pared to the composite grades, allowing for data clustering and the change of support effect. •The new MRE is broadly comparable to the previous 2021 version (Thor, 8 April 2021) and closely comparable to the 2023 MIK version (IVR, internal use/not publicly reported). The new model has: • been compared to the 2021 Thor model (at same cutoff criteria), for Measured and Indicated: lower tonnes but higher grade and higher density, for less overall contained WO3metal (91%). • been compared to the 2023 IVR model, for Measured and Indicated: tonnes are within 1%, slightly higher grade (by 2%) and same density, for more overall contained WO3metal (101%). |

| • differences between both that are mostly attributed to the overall smaller size of the con- straining wireframes (the 2023 IVR drilling helping to better define the two skarn bodies), ad- ditional DD drilling (some of which twinned or near-twinned historical holes) and a complete replacement of historical density data (replacement of all 2021 Thor density data) with the IVR 2023 density. For the Thor comparison there are also estimation methodology differ- ences. •These differences indicate that the new MRE takes appropriate account of these previous esti- mates. •The deposit was mined 1975 and 1976 (~20kt of molybdenum and tungsten) but there is insuffi- cient data available to perform a reconciliation study. However, cross-sectional plots within the area of the bulk samples (shafts and cross-cuts) of WO3estimates in the MIK block model appear to show good to very good agreement. Mining also occurred in between 1978-1982 down to 25m but again with insufficient data available. |

IVR regard this cut-off grade as appropriate on the basis of the stable and robust current tungsten price with a positive outlook and anticipated improved project economics. |

• Metallurgical and mineralogical analysis has been conducted on drill samples taken from explora- tion programs by Thor. • The metallurgical work by Thor has demonstrated successful molybdenum and tungsten recovery using a combination of gravity extraction and flotation processes. • Test work by Thor has demonstrated production of tungsten (as WO3) and molybdenum (as MoS2) concentrates in addition to a low-grade copper concentrate. • In Thor’s process flowsheet (Thor, DFS 23 August 2018), following comminution, molybdenum is floated, then copper is subsequently extracted via flotation of the pyrite flotation tail. Following these steps, a rougher scheelite is then recovered, again via flotation. The rougher scheelite concentrate is then upgraded using the Modified Petrov flotation model incorporating preheating the rougher product to 90⁰C. The current flowsheet also incorporates Xray ore sorting after the secondary screening stage. • A TOMRA ore sorting study undertaken in 2021 (internal study by Thor, not reported to the ASX), demonstrated potential recovery improvements for both tungsten (as WO3) and molybdenum (as MoS2). • IVR have undertakenpreliminaryreviews of metallurgyand identified a number of opportunities to |

| modify and potentially improve metallurgical processes, which will be tested further. | |
| Environmental factors or assumptions • Assumptions made regarding possible waste and process residue disposal op- tions. It is always necessary as part of the process of determining reasonable pro- spects for eventual economic extraction to consider the potential environmental im- pacts of the mining and processing opera- tion. While at this stage the determination of potential environmental impacts, particu- larly for a greenfields project, may not al- ways be well advanced, the status of early consideration of these potential environ- mental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made. |
• It is currently assumed that all process residue and waste rock disposal will take place on site in purpose built and licensed facilities. • All waste rock and process residue disposal will be done in a responsible manner and in accord- ance with any mining license conditions. •Existing historic mining activity has left existing waste and tailings on site and assumptions that disposal will be feasible are made, however environmental permitting and reviews on waste material risk are yet to occur. |
| Bulk density • Whether assumed or determined. If as- sumed, the basis for the assumptions. If de- termined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock |
• The bulk density at Molyhil is mainly reflective of the magnetite and tungsten content. • IVR’s reviews of previous work identified a number of concerns including (but not limited to): oa small portion of Fe assays in database were only analytically tested up to 50% Fe2O3. No over-range analytical method was used, thus limiting potential higher Fe during den- sity comparisons. oall samples taken had W and Mo present but a small portion had no accompanying Fe assays. othat no assessment of densities from drill core had been undertaken to review or aug- ment density assumptions. |

| and alteration zones within the deposit. • Discuss assumptions for bulk density esti- mates used in the evaluation process of the different materials. |
• During the 2023 drilling program IVR made a concerted effort to collect as much density data as possible utilising the Archimedes Wet/Dry method, in addition to undertaking DBD measure- ments of all available historic drill core. • Frequency of measurements was based on geology, with the more uniform unmineralised Mar- shall granite typically restricted to 1-2 measurements per tray of HQ core (~4m). In zones of skarn alteration and calc silicates, measurements were taken on every piece >10cm in length resulting in majority of drill core intersected having a DBD value in mineralised zones. • As a result, 1841 density measurements were collected during the drilling program. A further 1462 measurements were collected by reweighing historical HQ half core available at Thor’s core yard. • Check of Archimedes density was also undertaken on a selection of holes and trays via whole tray weight, and using average core length and diameter (vernier calliper) to calculate DBD and compare to Archimedes values. The results of these checks were comparable to the average lithological unit DBD values, confirming the accuracy of the method. • DBD for each sample was assigned as per noted above. |

| Classification • The basis for the classification of the Min- eral Resources into varying confidence cat- egories. • Whether appropriate account has been taken of all relevant factors (i.e. relative con- fidence in tonnage/grade estimations, relia- bility of input data, confidence in continuity of geology and metal values, quality, quan- tity and distribution of the data). • Whether the result appropriately reflects the Competent Person’s view of the deposit. |
• The classification scheme is based on the estimation search pass for WO3; Pass 1 = Measured, Pass 2 = Indicated and Pass 3 = Inferred. Pass 4 is not classified as part of the MRE but could be considered as a potential Exploration Target. • This scheme is considered to take appropriate account of all relevant factors, including the rela- tive confidence in tonnage and grade estimates, confidence in the continuity of geology and metal values, and the quality, quantity and distribution of the data. • The classification appropriately reflects the Competent Person’s view of the deposit. |
| Audits or reviews • The results of any audits or reviews of Min- eral Resource estimates. |
•Molyhil MRE’s in the past have been completed by a number of alternate consulting mineral re- source estimation companies with generally similar outcomes. •Thor initiated reviews of input data in December 2013 and September 2019 by consultants RPM to ensure compliance with JORC 2012 Code. RPM also verified technical inputs, methodology and parameters, in addition to conducting estimations. •In Thor’s 2021 MRE, consultants RES recommended implementation of an alternate estimation technique that removed previous “grade factoring assumptions” from the MRE (used mixed sup- ported kriging). •HSC in 2023 undertook a basic re-estimation review on the basis that provided data was valid (un- confirmed at the time) and noted that the 2021 MRE outputs by Thor appeared reasonable. •This new MRE has been reviewed by IVR personnel and peer reviewed by HSC and no material issues were identified. |

| Discussion of relative accuracy/ confidence • Where appropriate a statement of the rela- tive accuracy and confidence level in the Mineral Resource estimate using an ap- proach or procedure deemed appropriate by the Competent Person. For example, the ap- plication of statistical or geostatistical pro- cedures to quantify the relative accuracy of the resource within stated confidence limits, or, if such an approach is not deemed ap- propriate, a qualitative discussion of the fac- tors that could affect the relative accuracy and confidence of the estimate. • The statement should specify whether it re- lates to global or local estimates, and, if lo- cal, state the relevant tonnages, which should be relevant to technical and eco- nomic evaluation. Documentation should in- clude assumptions made and the proce- dures used. • These statements of relative accuracy and confidence of the estimate should be com- pared with production data, where available. |
• The relative accuracy and confidence level in the MRE are considered to be in line with the gen- erally accepted accuracy and confidence of the nominated JORC Mineral Resource categories. This has been determined on a qualitative, rather than quantitative, basis, and is based on the estimator’s experience with a number of similar deposits elsewhere. The main factor that affects the relative accuracy and confidence of the MRE is drill hole spacing, because there are no strong geological controls on the primary mineralisation. • The estimates are local, in the sense that they are localised to model blocks of a size considered appropriate for local grade estimation. The tonnages relevant to technical and economic analysis are those classified as Measured and Indicated Mineral Resources. •The deposit was mined between 1975-1976 and 1978-1982 but there is insufficient data available to perform a comparison or relative accuracy statement. However, cross-sectional plots within the area of the bulk samples (shafts and cross-cuts) of WO3 estimates in the MIK block model appear to show good to very good agreement. |
