MQR Expands Mt Clement (Eastern Hills) Inferred - Mineral Resource (MRE) by +69% Sb now Contributing 10,000t of Contained Metal

HIGHLIGHTS

• Marquee Resources Limited receives final assays from the phase 2 drilling campaign and expands Mt Clement (Eastern Hills) Inferred Mineral Resource (MRE) by +69% to 1.93Mt at 0.6% SbEq* for 11,000t SbEq of contained metal.

• Significant potential for Resource Expansion, zones open at depth and along strike.

• Phase three exploration drilling program scheduled to commence in March 2026.

• Company Chairman and Executives return from productive site visit to China to meet Executives from Yantai Jinao.

* Antimony equivalent values are based on antimony, lead, gold and silver prices of $US48,000/t, $2,000/t, $3,375/oz and $35.00/oz respectively and metallurgical recoveries[1] of 85%, 85%, 80% and 92% for these metals. These parameters give the following formulae: SbEq (%) = Sb (%) + 0.042 x Pb (%) + 0.21 x Au(g/t) + 0.0028 x Ag(g/t). They are based on Marquee’s assumed potential commodity prices and metallurgical test work reported by Artemis Resources Limited[1] for the Eastern Hills Deposit. It is the Company’s opinion that all elements included in the antimony equivalent grades have reasonable potential to be recovered and sold.

Marquee Resources Limited ( “Marquee” or “the Company” ) ( ASX:MQR ) is pleased to announce its updated Inferred Mineral Resource Estimate ( MRE ) at the Mt Clement (Eastern Hills) Project (“ Mt Clement or Eastern Hills ”) following on from the completion of the Phase 2 drilling program in late 2025.

The MRE, reported at cut-off grades of 0.15% SbEq and 0.35% SbEq for open pit and underground components respectively, totals 1.93Mt at 0.6% SbEq* for 11,000t of contained metal (Refer Table 1), with antimony contributing 10,000t of contained metal. Approximately 90% of the antimony metal is contained within the open pit component of the estimates .

Marquee Resources also declares an updated Exploration Target of approximately 2Mt to 4Mt with antimony grades of approximately 0.7% to 1.1% at Mt Clement (Eastern Hills). The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in estimation of a Mineral Resource.

Marquee Executive Chairman, Mr Charles Thomas, commented:

“This is a Company-making milestone for Marquee. Delivering an updated Inferred Mineral Resource Estimate (MRE) at Mt Clement (Eastern Hills) of 1.93Mt at 0.6% SbEq for 11,000t SbEq — including 10,000t of contained antimony metal — is a major step-change in scale for both the Project and the Company as a whole and further confirms we are building a genuinely meaningful (and possibly leading) antimony Company in Australia.”

“In an Australian context, a contained antimony inventory of this size announced today, places Mt Clement (Eastern Hills) amongst the leading antimony players nationally and reinforces the strategic importance of the broader Mt Clement system and the value that this Project can deliver for the Company and our Shareholders.”

“With antimony firmly recognised as a critical mineral and supply security now a central theme for governments and industry, an emerging Australian deposit of this scale carries real strategic weight. For Marquee, the value is now clear and immediate - this upgraded Resource strengthens our strategic optionality, materially improves our leverage in partnering and offtake discussions, and supports accelerated metallurgical and development workstreams as we continue to grow the system.”

“We believe Mt Clement (Eastern Hills) has rapidly become a cornerstone asset for the Company and will be a significant driver of shareholder value in the coming months and years.”

“Equally exciting is the acceleration we’re seeing on the broader strategic pathway. Last week in China I had the privilege of meeting with executives and representatives of Yantai Jinao, and I’m particularly pleased with the excellent relationship I have developed with Yantai Jinao’s Chairman, Mr Wang. The engagement was highly constructive and solutions-focused, and we are well aligned on advancing both upstream development and downstream partnership opportunities at Mt Clement (Eastern Hills). Marquee is working to position Mt Clement as a credible, strategically important source of antimony supply, and we believe these discussions with Yantai Jinao will turn out to be an extremely important step in that direction, when we look back at the progress that was made at Mt Clement during 2025/2026 in years to come.”

“Finally, I wish to genuinely thank our team of geologists and the wider team at Marquee for their tirelessly hard work and dedication in delivering this key milestone for the Company today. It is much appreciated by me and the Board and the real praise for delivery of this milestone should be with them.”

Phase 2 Drilling Program

The Phase 2 drilling program covered all three known Sb zones (Taipan, Gwardar and Dugite), delineating eight new mineralised structures, with estimates for five of these included in the updated MRE.

For the updated MRE, antimony rich mineralisation is modelled as nine discrete lode structures over three domains (see Figure 1), separated by oblique faults with apparent strike-slip displacement. The western block comprises five Taipan structures with a new Dugite structure. Between the two faults, the Taipan zone is observed to be offset with moderately southeast dipping structures, and the Gwardar Zone comprises two structures, with only one of these included in the updated inferred resource at this stage (refer Figure 1 and Figure 2). To the northeast the second eastern fault mineralisation remains underexplored and is currently classified as a target area, representing further potential upside to the size of the Resource at Mt Clement (pending additional drilling).

Table 3 lists the complete set of drill holes within Marquee’s tenement that inform the MRE and Table 4 lists the significant intercepts for these holes, calculated at a cut off of 0.10% Sb and minimum down-hole length of 1 m. Higher grade portions of significant intercepts are selectively shown for grades exceeding 0.3% Sb to effectively characterise the grade distribution of mineralisation.

Exploration Target at Mt Clement (Eastern Hills)

The Exploration Target at Mt Clement (Eastern Hills) of approximately 2Mt to 4Mt with antimony grades of approximately 0.7% to 1.1% (refer Figures 2 and 3) has been interpreted based on the following:

• Strike extension Target Structures (as delineated in Figure 1). The two most significant Target Structures are hosted in the Taipan and Dugite Zone and are each interpreted to strike over approximately 200 m;

• Mineralised rock chip sample beyond the current open pit outline;

• Depth extensions to all three high-grade domains of the underground model which remain open at depth (refer Figures 2 and 3).

WWW.MARQUEERESOURCES.COM.AU

==> picture [106 x 57] intentionally omitted <==

The upcoming Phase 3 drilling Program commencing in March aims to test the Exploration Target, including new planned drill holes targeting the strike extension, target structures and depth extensions of the underground Resource. The drilling is also designed to provide representative mineralised samples for ongoing metallurgical test work by Yantai Jinao, enabling material derisking in tandem with Resource expansion.

Metallurgical Test work and Strategic Engagements Progressing

Marquee has now delivered two shipments of high-grade antimony-lead-silver ore to Yantai Jinao, who have commenced metallurgical test work. The first sample met expectations in terms of grade and sample quality, prompting the submission of a second, higher-grade sample representing Mt Clement (Eastern Hills) material from the Phase 2 drilling. This follow-up sample was designed to test performance at higher grades and better reflect potential production scenarios.

Discussions with Yantai Jinao are ongoing, with a meeting of the Chairmen and executives of both Marquee and Yantai Jinao occurring last week in China. These meetings are expected to play a key role in advancing the upstream and downstream strategic pathways for the Project.

Marquees Mt Clement antimony Project which adjoins Black Cat Syndicate’s (ASX:BC8) antimony deposit (which is quoted as “Australia’s Largest Undeveloped Antimony Deposit”), is now positioned to become a cornerstone asset of Marquees in establishing a secure antimony supply chain. These full suite of results and significantly upgrade MRE, confirm robust grades and consistent mineralisation, validating Marquee’s strategy to aggressively advance exploration and development of this Project.

Figure 4 – Mt Clement Project tenure and major geological structures.

The Mt Clement Project is located 30km SW of Black Cat Syndicate’s (ASX:BC8) Paulsens gold mine (Figure 4), at the western end of the Ashburton Basin in the northern Capricorn Orogen. Mineralisation at the Mt Clement deposit (ASX:BC8) includes of gold, copper, antimony, silver, and lead with arsenic a key indicator. Marquee’s Mt Clement Eastern Hills Project is contiguous on the eastern flank of the Mount Clement Antimony Mineral Resource now owned by Black Cat Syndicate Ltd. Black Cat has stated that its portion of this antimony deposit is Australia’s largest undeveloped antimony Project and the fourth largest antimony Resource in Australia comprising 794kt @ 1.7% Sb (~13kt), +Au, +Ag).[2]

The Company has identified several prospects (Mt Edith, Yandi Well, Blackadder and Lady Marian) in addition to Eastern Hills, where potential antimony and gold mineralisation will be further targeted. The Ashburton Basin is an underexplored terrain in the west Pilbara, host to numerous examples of Au, Pb-Ag and Cu mineralisation.

ASX Listing Rule 5.8.1 & JORC 2012 Reporting Guidelines

The following is a summary of material information used to estimate the Mineral Resource, as required by Listing Rule 5.8.1 and JORC 2012 Reporting Guidelines.

Geology and geological interpretation

Marquee’s Mt Clement Project is located in the Ashburton Basin which is characterised by Proterozoic meta-sedimentary and meta-volcanic rocks. Within the project area, rocks of the Ashburton Formation crop out as sandstones, siltstones and mudstones. Prominent NE-SW striking dolerite dykes of the Black Hill Suite are often continuous over several kilometres.

At Marquee’s Mt Clement (Eastern Hills) Deposit, Sb-Pb-As-Ag veins are hosted in numerous, sub-parallel quartz-sulphide lodes. The mineralisation comprises a boulangerite and jamesonite assemblage with minor galena and accessory arsenopyrite, pyrite and pyrrhotite. Silicification of disseminated sulphide bearing meta-sediments typifies the alteration halos.

The mineralisation is interpreted as post-dating the nearby (~1.2 km) syngenetic stratabound Mt Clement Gold Deposit. Eastern Hills mineralisation may represent syn-metamorphic remobilisation and substantial recrystallisation from massive sulphide mineralisation.

Sampling and sub-sampling techniques

Marquee Resources Limited

• The rig-mounted cyclone and splitter was orientated vertically using spirit levels at the start of each drill hole and checked during drilling activities.

• The cleanliness of the rig-mounted cyclone and splitter was routinely checked by the offsiders throughout the drill program and cleaned down by air hose when required.

• Approx. 2.5kg primary samples in pre-labelled calico bags representing one metre drilling intervals were sampled directly from the rig-mounted cyclone and cone splitter.

• Compositing of unmineralised intervals (aided by visual assessment of chips, logging and Olympus pXRF) of between 2 - 4m was undertaken to generate a ~2.5kg sample.

• Sample sizes are considered appropriate to give an indication of mineralisation given the particle size.

• Primary 1m and composited (2-4m) samples (<3 kg mass) were pulverised with 85% passing - 75µm. Samples in excess of 3kg were crushed and split prior to pulverising.

Artemis Resources Limited

• The RC drilling rig was equipped with an in-built cyclone and triple tier riffle splitting system, which provided one bulk sample of approximately 20kg, and a sub-sample of 2-4kg per metre drilled.

• All samples were split using the system described above to maximise and maintain consistent representativity. The majority of samples were dry. For wet samples the cleanliness of the cyclone and splitter was constantly monitored by the geologist and maintained to avoid contamination.

• Bulk samples were collected in large plastic bags, with the sub-samples collected in calico sample bags.

• Field duplicates were collected by re-splitting the bulk samples from large plastic bags. These duplicates were designed for laboratory checks as well as umpire analysis.

• A sample size of 2-4kg was collected and considered appropriate and representative for the grain size and style of mineralisation.

Taipan Resources NL

• Four-metre composite samples were taken and fire assayed for Au, Ni, Cu, Pb, Zn, Ag, As and Sb.

• Encouraging results from the four metre composites prompted follow up sampling of one metre samples which were assayed for the same suite of elements.

Drilling Techniques

All holes were drilled utilising RC drill rigs with face sampling bits of 114-124 mm diameter. Downhole gyroscopic surveys were conducted for Marquee and Artemis drillholes. No downhole orientation surveys were conducted for Taipan’s drilling. Most drillholes were collared orientated towards the northwest, broadly perpendicular to strike of mineralised lodes.

Sample Analysis Methods

Marquee Resources Limited

• Sample preparation and assaying was completed by ALS Perth using the XRF-15b method for analytes Sb and Pb for total digestion. This method targets comprises fusion (12:22 lithium metaborate - lithium tetraborate flux containing 20% NaNO3) with XRF finish.

• Additional assaying for multi-element ICP and fire assay methods were reported in September 2025.

• Duplicate field samples were collected from the opposite side of the cone splitter averaging around 1 per 30 primary samples.

• Samples of Certified Reference Material (CRM) were inserted at a frequency averaging of around 1 per 30 primary samples.

Artemis Resources Limited

Estimation Methodology

Open pit and underground components of the Mt Clement (Eastern Hills) Mineral Resource are respectively derived from two block models generated from RC drilling information available for the Project in February 2026. Both models cover Mt Clement (Eastern Hills) mineralisation intersected by drilling to date, with Mineral Resources including only mineralisation material within Tenement E08/3214.

The Mineral Resource Estimates are tested by variably spaced drilling approximating 40 to 80 m spaced traverses. Subset to the Resource volume, Marquee drilling provides around 39% of the estimation dataset with Taipan and Artemis drilling respectively contributing around 26% and 35%. The estimates are extrapolated to a maximum of around 100 m from drilling, within around 91% of the estimates within 70 m of drilling.

The Open Pit and Underground Resource models incorporate generally steeply southeast dipping to subvertical wire-framed mineralised domains capturing SbEq grades of generally greater than 0.1% and 0.35% respectively. The mineralised domains were interpreted with a minimum down-hole intercept length of generally around 3 m, representing around 1.5 m true width with some lower grade intervals included for continuity.

Within E 08/3214 the Inferred open pit model estimates incorporate nine mineralised domains comprising a West Main and adjacent West South domain, which respectively host around 56% and 22% estimated open pit resources and seven subsidiary zones which each contribute between 1% and 6% of the estimates. Underground Mineral Resource Estimates include estimates for the West Main domain (98%) and West South (2%) zones.

A surface representing the base of weathering interpreted from geological drill hole logs, which averages around 40 m depth was used for density assignment.

For each metal, block grades were estimated by Ordinary Kriging of one metre down-hole composited assay grades within the mineralised domains.

The modelling utilised 40 by 2 by 20 m parent blocks with sub-blocking at domain boundaries. For grade estimation, composites were unfolded to remove domain undulations and estimated model blocks back transformed to real-world coordinates. Kriging of Sb, Pb, Au and Ag grades utilised a variogram model interpreted from composite Sb grades reflecting the comparatively early stage of project assessment and the generally strong correlation between these metal grades. Estimation incorporated upper cuts

13

==> picture [106 x 57] intentionally omitted <==

approximating the 99[th] percentile of each metal grade in the combined dataset reducing the impact of a small number of outlier composite grades on the estimates. Resource estimation used eight progressively relaxed search passes selected from on the drill hole spacing and mineralisation trends to inform a reasonably large proportion of the mineralised domains while allowing blocks to be estimated by reasonably close data where possible.

No bulk density measurements are available for the deposit and the assigned densities of 2.4 and 2.6 t/bcm for weathered and fresh mineralisation respectively were selected on the basis of Competent Person’s experience of densities for comparable mineralisation styles.

Micromine software was used for data compilation, domain wire framing, coding of composite values and pit optimisation. GS3M was used for resource modelling. The estimation methodology is appropriate for the mineralisation style.

Classification Criteria

The Estimates are classified as Inferred, primarily reflecting the comparatively broad drill hole spacing.

Potential for reasonable prospects of eventual economic extraction

To provide Estimates with reasonable prospects of eventual economic extraction, open pit resources are constrained within an optimal pit shell generated by cost and revenue parameters specified by Marquee, as summarised in Table 5. Unit costs reflect Marquee’s interpretation of potential moderate scale, selectively conventional open pit and underground mining and processing by floatation. The metallurgical recoveries are based on Artemis Resources Limited (ASX:ARV) April 2014 metallurgical test work program. For that program, Core Process Engineering tested three RC chip composite samples from the Eastern Hills Deposit, including sample EHMET001 comprising bulk samples from 164-168 m of drillhole AREHRC002 now wholly contained in Marquee tenure E 08/3214.

Cut-off grades used for open mineral resource reporting reflect these cost and revenue parameters.

JORC CODE, 2012 EDITION – TABLE 1 REPORT

Section 1 Sampling Techniques and Data

Criteria	JORC Code explanation	Commentary
Sampling techniques	• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation 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 required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.	Marquee Resources Limited • 21 reverse-circulation (RC) holes for 4,254 m have been completed during 2025, approx. 203 m average max depth. • RC drilling was completed using a 124 mm face sampling hammer. • Drill spoils were sampled via the onboard cyclone and cone splitter at intervals of every 1 m and placed in piles with corresponding labelled calico bag for sampling by MQR geologists. • Sampling involved collection of calico bags and insertion of calico bagged (blind) QAQC certified reference material in sequence. • Samples were sent to the laboratory for XRF, fire assay and ICP analysis (further details below). • Sampling was carried out under the Company’s protocols and QAQC procedures as per industry best practice (further details below). Artemis Resources Limited • Seven RC holes are collared within E08/3214 (Table 3 in main body). • Reverse circulation drilling was used to obtain 1m drill chip samples from which a 2-4kg sample was collected for submission to the laboratory for ICP and XRF analysis. • Samples from each metre were collected in a cyclone and split using a 3-level riffle splitter. Artemis used a hand-held XRF to obtain an instant qualitative geochemical analysis of each sample during the drilling. Taipan Resources NL • Six RC holes from 1996 & 1997 drilling are collared within E08/3214 (Table 3) • Reverse circulation drilling was used to obtain 1m drill chipsamples.

Section 3 Estimation and Reporting of Mineral Resources

(Criteria listed in section 1, and where relevant in section 2, also apply to this section.)

Criteria	JORC Code explanation	Commentary
Database integrity	• Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. • Data validation procedures used.	•Marquee adheres to strict approval and export procedures for assay results and geological logging data. •Database entries are routinely validated by company personnel using a variety of software packages.
Site visits	• Comment on any site visits undertaken by the Competent Person and the outcome of those visits. • If no site visits have been undertaken indicate why this is the case.	•Mr Currell has visited the site many times, most recently November 2025. Outcomes from these visits include field mapping, rock chip sample collection, soil sampling and RC drill rig geology and program management. •Mr Gokler has conducted multiple site visits and has been actively involved in drill program management, geological interpretation, and database oversight. His involvement included supervision of drilling activities, real-time geological logging review, structural interpretation, and validation of data inputs supporting mineralisation models and resource estimation work. •Mr Abbott has not visited the project. While undertaking this study, Mr Abbott worked closely with Marquee geologists and the mineralisation interpretations underlying the estimates are consistent with Marquee’s geological understanding of the deposits.
Geological interpretation	• Confidence in (or conversely, the uncertainty of ) the geological interpretation of the mineral deposit. • Nature of the data used and of any assumptions made. • The effect, if any, of alternative interpretations on Mineral Resource estimation. • The use of geology in guiding and controlling Mineral Resource estimation. • The factors affecting continuity both of grade and geology.	•Eastern Hills mineralisation is interpreted to be hosted in several quartz-sulphide lodes which cross-cut bedding in the metasedimentary rocks of the Ashburton Formation and are cross cut by several cross cutting faults. •The mineralised lodes trend broadly northeast-southwest and generally dip steeply to sub-vertically southeast. Several domains in the east of the project dip at around 60otowards the southeast. •The project is at an early stage of evaluation and secondary controls have not yet been confidently established. Uncertainty in geological controls is reflected by classification of the Mineral Resources as Inferred. •The mineralised domains used for resource modelling and are consistent with geological interpretations of drill hole logs and surface exposures. •A surface representing the base of weathering interpreted from drill hole logging, which ranges from around 5m to 75m depth and averages around 40m depth was used for density assignment. •Confidence in the geological interpretation is sufficient for the current resource estimates. Alternative interpretations are considered unnecessary.

Within this trimmed pit shell, the domains informing open pit mineral resources have the following contributions to the estimates, and approximate strike, vertical extents from surface and average horizontal width: oWest Main (56%), 280 m, 260 m, 9.0 m oWest South (22%), 310 m, 250 m, 4.1 m oWest Far South 1 (6%), 150 m, 240 m, 2.1 m oWest Far North (3%),110 m, 130 m, 1.9 m oWest North (2%), 60 m, 110 m, 2.4 m oCentral South (5%), 170 m, 90 m, 2.7 m oCentral Mid (1%), 50 m, 80 m, 4.1 m oCentral Far North (4%), 150 m, 50 m, 3.9 m oWest Far South 2 (1%), 60 m, 190 m, 1.8 m •The Underground resource model includes wire-frame interpreted for the West Main and West South mineralised domains capturing drill sample grades with SbEq grades of generally greater than 0.35%. Underground Mineral Resources are constrained below the open pit resource shell and extend to a maximum vertical depth from surface of around 300 m. The mineralised domains have the following contributions to the estimates, and approximate combined strike, vertical extents and average horizontal width: o West Main (98%), 230 m, 60 m, 4.5 m o West South (2%), 80 m, 20 m, 2.2 m
Estimation and modelling techniques	• The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. • The assumptions made regarding recovery of by- products. • Estimation of deleterious elements or other non-grade	•Open pit and underground Mineral Resources were estimated from block models incorporating wire-framed mineralised domains capturing SbEq grades of generally greater than 0.1% and 0.35% respectively. The domains, which were interpreted in conjunction with Marquee geologists generally dip steeply south-southeast to sub- vertical with several domains in the east of the deposit interpreted to dip at around 60otowards the southeast. The domains were generally interpreted with a minimum down-hole intercept length of around 3 m, representing around 1.5 m true width. Some lower grade intervals were included for continuity. •Both models cover Mount Clement mineralisation intersected by drilling to date, with Mineral Resources including only mineralisation within estimates within E08/3214. •Within E08/3214 the open pit model incorporates nine mineralised domains including a West Main and adjacent West South domain, which respectively host around 56% and 22% estimated open pit resources along with seven subsidiary zones which each contribute between 1% and 6% of the estimates. Mineral resources reported from the underground model include only the West Main domain and West South domains. •The mineralised domains are consistent with geological interpretations of drill hole logs and surface exposures. A surface representing the base of weathering interpreted from drill hole logging, was used for densityassignment.

The open pit model utilised Sb, Pb, Ag and Au upper cuts of 5%, 11%, 100 g/t and 2.0 g/t respectively. The underground model employed Sb, Pb, Ag and Au upper cuts of 6%, 12%, 105 g/t and 2.5 g/t respectively. •Kriging of Sb, Pb, Ag and Au grades utilised a variogram model interpreted from composite Sb grades. This approach reflects the comparatively early stage of project assessment and the generally strong correlation between these metal grades. •Micromine software was used for data compilation, domain wire framing and coding of composite values and GS3M was used for resource estimation. The resulting estimates were imported into Micromine for pit optimisation and resource reporting. •The modelling did not include estimation of any deleterious elements or other non-grade variables. Rare estimation dataset composites from Taipan drilling without Pb assays including 7 (1%) within the resource volume, lead grades were assigned from a Pb vs. Sb function derived from composites with assays for both metals. •The modelling approach is appropriate for the mineralisation style. •Reviews of the block model included visual comparisons of the model with the informing data. •The estimates are tested by variably spaced drilling approximating 40 m spaced traverses. Modelling utilised 40 by 2 by 20m parent blocks sub-blocked to minimum dimensions of 2 by 0.5 by 1 m at domain boundaries (strike, cross strike, vertical). •For grade estimation composites were unfolded to remove domain undulations and estimated model blocks back transformed to real-world coordinates. •Mineral resource estimation included a seven-pass search strategy with (strike, cross strike and down-dip) radii and minimum data requirements as follows: oSearch 1: 40, 2, 40 m, minimum 6 data oSearch 2: 60, 3, 60 m, minimum 6 data oSearch 3: 60, 3, 60 m, minimum 3 data oSearch 4: 160, 8, 160 m, minimum 3 data oSearch 5: 160, 8, 160 m, minimum 3 data oSearch 6: 160, 8, 160 m, minimum 2 data oSearch 7: 240, 8, 240 m, minimum 3 data oSearch 8: 480, 16, 480 m, minimum 3 data •Mineral resources are primarily informed by search passes 1 to 5 which inform around 97% of the estimates, with search 6 informing around 3% and searches 7 and 8 contributing only small amounts. •Mineral Resources are extrapolated to a maximum of

No bulk density measurements are available for the deposit and the assigned densities of 2.4 and 2.6 t/bcm for weathered and fresh mineralisation respectively were selected on the basis of the competent persons experience of densities for comparable mineralisation styles determined from oven dried diamond core samples and mine production.
Cut-off parameters	• The basis of the adopted cut- off grade(s) or quality parameters applied.	•The cut-off grades selected for reporting reflect Marquee’s view of potential project economics
Mining factors or assumptions	• Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made.	•The open pit and underground models reflect moderate scale selective mining, with minimum mining widths of around 1.5 m. Optimisation parameters for the pit shell constraining open pit resources included mining dilution of 10%.
Metallurgical factors or assumptions	• The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made.	• Economic evaluation of the Eastern Hills deposit is at comparatively an early stage. Marquee have not yet evaluated metallurgical considerations for potential mining in detail. However, recovery results from metallurgical test work reported by Artemis Resources Limited for the Eastern Hills indicates that there are unlikely to be any specific metallurgical issues that would preclude potential eventual economic extraction.
