04[th] April 2023

64% INCREASE OF MT CARBINE INDICATED RESOURCES (IN-SITU)

EQ Resources Limited is the 100% owner of the Mt Carbine Tungsten Mine near Cairns, Australia’s only primary tungsten producer.

Highlights:

  • Updated Mt Carbine Mineral Resource Estimate (“MRE”) confirms an increase of 64% metal contained in Indicated Resources (In-situ), adding ~2.11 million mtu*.

  • Global MRE (Inferred- & Indicated category) increases by 28.6% to ~9.61 million mtu**.

  • Indicated Resources (In-situ) expanded from 12Mt @ 0.27% WO3 to 18.1Mt @ 0.30% WO3, adding significant metal value to the Company’s inventories.

  • The high-grade mineralisation located in the Dyke West Zone and the Northern Iron Duke Zone in recent drilling program is driving this MRE expansion, with mineralisation remaining open at depth and along strike.

  • Work continues to update the Mt Carbine Ore Reserves through a potential Western Pit Expansion and additional drilling to commence in the coming weeks.

* 0.05% WO3 cut-off grade ** mtu = metric ton unit, equals 10kg WO3

EQ Resources Limited (“EQR” or “the Company”) is pleased to provide the revised Mt Carbine MRE that includes the successful Phase 2 2022 drilling program, with significant high-grade mineralisation intersected (see ASX announcement ‘Drilling Results Highlight Significant Iron Duke Discovery And Potential For Additional Pit Expansion’ dated 13 February 2023, and ASX announcement ‘Drilling Confirms High-Grade Mineralised System in Western Extension’ dated 27 February 2023). Total drilling to date at Mt Carbine used for this MRE Update comprises 96 holes for 24,337m of diamond drilling.

The update resulted in a 64% increase in the Indicated Resources (In-situ) Category by adding 2,109,101 mtu. Global MRE inventory went up by 28.6% for a total increase of 2,136,338 mtu. The extension drilling around the Dyke West Zone and Northern Iron Duke Zone was principally responsible for the significant increase in metal inventory at Mt Carbine.

The Company is currently reviewing and optimising the latest open pit design which together with the significant MRE upgrade will form a very strong basis for a revision of the Mt Carbine Ore Reserves.

EQR’s Chief Executive Officer, Mr Kevin MacNeill, commented: ‘’This upgrade to the mineral resource base at Mt Carbine by adding 2.14 million mtu to our global resource base is a substantial value driver for EQR and its shareholders moving forward. Importantly, this larger resource gives the Company significant options for expansion since most of this increase has now been brought into the Indicated Resource Category and thus forms the basis for the Ore Reserve update due in a few weeks.”

The Company is now in a position to model a larger pit to expand from the current 4 year BFS pit as per the revised BFS Economic Update of November 2022. The high-grade mineralisation recently intersected still remains open further to the west, north and to depth and the Company flags it will continue to drill this year to further expand this world-class tungsten resource.

“The target has always been a long life open pit operation followed by, or in sequence to, a long life underground operation. The Company’s immediate priority is to put this additional resource into our financial model to plan a larger pit and extend open pit mine life’’, Mr MacNeill adds.

The updated MRE is reported in accordance with the 2012 JORC Code and summarised as follows:

  4. The deposit is sheeted vein system with subparrallel zones of quartz tungsten mineralisation that extends for >1.2km in length and remains open to the west and north. At depth the South Wall Fault cuts the Iolanthe to Johnson's veins but the Iron Duke zones remain open to depth.

Figure 1 - Mt Carbine Mineral Resource Estimate as of April 2023

The Company remodelled this MRE with a similar set of parameters as defined by the Measured Group when calculating the June 2021 and August 2022 Resource Statements with only minor modifications (for details see ‘Annex 1 - Mineral Resource Statement’). The calculation used a ‘Kriged Variable Orientated Estimation’ methodology for the model. It was found the single variogram applied in previous estimations was not suitable for the western extensions where changes in vein orientations were observed. The strike changes of the veins in this area moved from grid east-west to grid south-west and was recorded from surface mapping of the veins as well as reflected in the recent orientated drill core.

The updated MRE uses the same 0.05% WO3 cut-off as defined in our previous Resources and Reserves Statements (see November 2022 Updated Bankable Feasibility Study). The lower grade portion of these Resources is designated for storage into the Company’s low-grade stockpiles which are currently being mined at a grade of 0.075% WO3, whilst the >0.08% WO3 portion is marked into the Company’s In-situ Resources Category.

One of the key aspects of the Mt Carbine tungsten deposit is the potential to lift the grade mined to match any variations in economic circumstances. Much of the world’s tungsten deposits do not have the high-grade core that exists at Mt Carbine. The Company is well advanced to commence open pit mining operations at the Andy White Pit with plans for 760,000t @ 0.44% WO3 ore in the first year. Earthmoving contractor Golding begins mobilisation in May 2023 for mining to commence in June 2023.

ANNEX 1 - MINERAL RESOURCE STATEMENT

Mineral Resource Estimation Overview

Pursuant to ASX listing rule 5.8.1., and in addition to the JORC tables (see Annex 2), the Company provides the following in respect to the Mt Carbine Mineral Resource Estimate (“MRE”).

The following revised MRE being issued on 04 April 2023. This Resource Statement includes detailed variogram modelling that includes additional data from drilling conducted in February 2023. (see ASX announcement ‘Drilling Results Highlight Significant Iron Duke Discovery And Potential For Additional Pit Expansion’ dated 13 February 2023, and ASX announcement ‘Drilling Confirms High-Grade Mineralised System in Western Extension’ dated 27 February 2023).

The MRE for Mt Carbine consists of two separate components:

  1. In-Situ Mineral Resources adjacent to, and below, the current open pit, proposed to be mined by open pit and underground mining methods; and

  2. The mineralised rock previously mined and stockpiled, located in what is now referred to as the Low-Grade Stockpile (“LGS”). The resource statement for the LGS was not re-estimated in this review other than to reduce the available tonnes from 12Mt to 10.126Mt due to current trial mining activities during 2022 & 2023. Suffice to say that the grades continue to be verified during this trial mining at being 0.075% WO 3 . The reader is pointed to the resource statement of 23 September 2021, where the detailed calculations and methodology are outlined for the LGS. This work was completed by the independent consultant known as the Measured Group.

This MRE was finalised on 04 April 2023 and is based on a re-run of resources using all the geological database acquired to date including 24,337m of diamond core in 96 diamond drill holes. These holes have for the most part intersected the in-situ orebody adjacent to, and below, the current open-pit.

The JORC 2012 compliant resource estimated for Mt Carbine as outlined on the 04 April 2023 is as follows

Geology and Geological Interpretation & Sampling Methods.

EQ Resources completed this MRE using criteria as outlined in this statement. The differences from previous Resources Estimates completed by the Measured Group (see EQ Resources website ‘Technical Reports; 2021 Resource Report December dated 3[rd] December, 2021 & 2022 Resource Report July dated 21[st] July,2022 is principally the details of variogram modelling. The variogram of the Measured Group was a single variogram applied to the entire resource whilst EQ Resources work showed that the veins moved orientation in the western portion of the deposit. The procedure to install a variable orientation estimation was to outline the vein trend from surface mapping of the veins, historical underground workings maps and the orientation of the veins in the diamond drill core using high quality vein orientation measurements.

The veins occur as distinct white quartz-tungsten veins of 5-200cm in width with the main ore zone occurring between the Reduced Levels (RL’s) of 100 to 350m RL. The veins occur in multiple sets of sheeted veins that make distinctive ‘package’ zones. The individual veins in the ‘packages’ are often from 0.5m to 5m apart, whereas between packages the vein separation is typically 10-20m. The better mineralised zones of the Iolanthe, Bluff & Johnson packages, typically have from 10-15 veins that make up the vein zone. Internally in the vein zone package, veins do merge and bifurcate, pinch and swell and truncate, but for the most part are sheeted in their format. This is demonstrated on the global project scale where subparallel veins are repeated over more than 500m width and >1km strike with a total of 7 vein packages so far identified and mapped out.

The database for the estimate has grown to 96 drill holes for 24,337m of diamond drilling that has all been geologically and geotechnically logged, and photographed. Approximately, 22% of the core has been assayed with all veins being included. Core was split using diamond saw cut along the same determined orientation to keep the consistency of sampling. All samples were prepared to recommended powder before a fusion disk XRF-15b analysis by ALS in Brisbane.

Lithological, structural and assay data from the 96 diamond core drill holes, which are spaced between 20m and 75m apart, were used to build the mineralisation wireframes which is used to constrain the block model. Checks of the documentation describing the sampling, sample preparation, QA/QC protocols and analytical procedures used for all the drilling phases were completed by the Competent Person responsible for the estimate.

No compositing of core sample intervals was undertaken in the field. Samples were composited within the mineralisation envelopes for geological modelling. Data spacing was considered sufficient for the estimation of WO3 grades by ordinary kriging. Mineralisation was modelled as three-dimensional blocks of size 5 m x 5 m x 1 m. No assumptions were made regarding the modelling of selective mining units but veins were mapped into their orientation domains and modelled using variable orientation estimation variography.

The following validation checks were completed on the block model:

  • Drill holes used for the estimation plotted in expected positions.

  • Flagged domains intersections lay within, and corresponded with, domain wireframes.

  • Determine whether statistical analyses indicated that grade cutting was required.

  • Volumes of wireframes of domains matched volumes of blocks of domains in the block model.

  • Visually plot of grades in the block model against drill holes.

The MRE was completed on the basis that the in-situ Mineral Resource will be mined by either open-cut or underground mining methods. Given the proximity of the modelled orebody to the current open pit, the MRE has been deemed by the Competent Person to pass the “reasonable prospects for eventual economic extraction test” (RPEEE). EQ Resources is currently preparing to mine in Q3, 2023 the reserves as outlined in the December 2022 Bankable Feasibility Study (“BFS”) Update. These resources include these reserves and have expanded beyond the current BFS.

Cut-offs

No upper cut-off grades were applied to the Mt Carbine Resource Estimate. The Competent Person established to his satisfaction that the high-grade zones recorded in the drill results were present in the

mineralized zones and could be correlated between sections. A lower cut of 0.05% WO3 was used to determine the resource and to define the geological boundaries to the mineralized zones. The Competent Person completed an assessment of tonnes by grade table to assist in the determination of the cut-off grade.

Cut-Off Grades

The 04 April 2023 MRE is based on a detailed review of the project completed by EQR. It has incorporated EQR’s current view of near and long-term tungsten prices, cost assumptions, plus mining and metallurgy performance to select cut-off grades and physical mining parameters. The 18 months of trial mining of the 0.075% WO3 LGS has demonstrated clearly the economics of the project and the viability for including grades above this as Resources. Existing geological and mining models show that the quoted Resource has “reasonable prospects for eventual economic extraction” as required by the JORC Code (2012).

The updated MRE uses the same 0.05% WO3 cut-off as defined in our previous Resources and Reserves Statements (see November 2022 Updated Bankable Feasibility Study). The lower grade portion of these Resources is designated for storage into the Company’s low-grade stockpiles which are currently being mined at a grade of 0.075% WO3, whilst the >0.08% WO3 portion is marked into the Company’s In-situ Resources Category.

Variography & Classification

A complete review of the variography was undertaken using the following information:

  1. Historical miners mapping of the workings, including the line / orientation of the veins.

  2. Review of R&B data from previous open pit works including both structural and detailed vein mapping.

  3. Review of structure by independent consultant Nick Oliver that allows an understanding of the structural setting and likely vein orientations.

  4. Relogging of historical holes (all of which are in good condition at site). Review using modern computerisation of the veining to determine vein packages.

  5. Recent surface vein tracings and observations of existing workings trends.

  6. 33 orientated diamond drill holes data computerized and in 3D that enables the individual veins and packages to be observed.

  7. Detailed core photography that allows for integration of old and new drill holes.

  8. Trend lines computerised for different vein Domains that match all the relevant data.

  9. Determining the range of different vein orientations.

As per Measured Groups Methodology to ensure there is a strong correlation between actual drill hole values and the estimated block model a new set of variable orientation variograms were generated. This model was estimated using ordinary kriging.

==> picture [318 x 195] intentionally omitted <==

Figure 7 - Vein Variography

The mineralisation at Mt Carbine was interrogated along all 3 primary axis’s to determine the best direction for establishing continuity. The strike of the veins is the greatest variable in the modelling due to vein orientation changes and using a variable orientated estimate along strike lines of the mineralisation best represented the field observations. Veins are persistent but do bifurcate and merge with variations in orientations along different vein packages. The following plan shows the variable orientation estimation method. The modelling creates a variogram change as it sees the strike and attitude of the vein changing.

Classification

The Mt Carbine Tungsten Mine MRE has been classified by the Competent Person as Indicated and Inferred Mineral Resource categories, based on the current understanding of the continuity of the orebody geometry (geology) and grade. The classification reflects the Competent Person’s confidence in the location, quantity, grade, geological characteristics, variography and continuity of the Mineral Resource.

The veins have been mapped and drilled and are predictable with high-grade zones being repeated from section to section. The veins have distinctive signature of morphology and format with variable ratios of

scheelite vs wolframite that assist to identify the individual veins. Veins do wander over several meters and in some cases there are clear off-shoots and localised ladder veins. Moreover, the veins occur in regular packages with the veins on the margins of the package often being the higher grade veins.

Categories used for classification are:

  • 30 x 30m centres for Indicated Resources

  • 80 X 80m centres for Inferred Resources

In the author’s opinion the veins have demonstrated clear continuity at the drill spacing of 30m centres to be Classified under the JORC 2012 Definition as Indicated Resources. The style of mineralisation, data quality and excellent QAQC data all reflect confidence in this resource. The application of 30m centres for Indicated Resources is same standard as applied by Measured Group in the previous two MRE’s, and the author agrees with this criteria as it provides the necessary detail for linkage of veins & packages.

Drilling up to 80m centres where both the vein package and individual veins still can be recognised are considered by the author to be inferred. Beyond 80m centres the mineralisation is designated as Exploration Potential.

Block Modelling (In-situ Zone)

Creation of the block models were constructed using Leapfrog v2022 1.1 3D modelling software. The block model for the In situ Zone was created for the deposit with the extents and block size shown in both visual and table form here.

Data

The block model has 96 holes and 24,337m of diamond drilling. The total sample database consists of samples that represent ½ core that has been entirely pulverised to appropriate fineness and sampled for assay using fusion disk XRF15b methodology at ALS Laboratory. Further details of sampling & protocol methodology are listed in the attached JORC tables 1 & 2.

The inputs into the In-situ Zone for the block model includes topography, orebody grade shells, weathering wireframes, estimation data, density, and resource classification. Block sizes were determined from sample length within the assay data set. The variables used in the modelling include the following:-

ORE - Ore domains, WO3% tungsten grades with subsets of package composites, DENSITY - detailed density data, MinD – being distance to closest sample AvgD – average distance to samples, RESCLASS – resource classification, KE - Kriging efficiency, KV – Kriging variance, NS of samples to estimate block, SoR – slope regressions, SumN – sum of negative weights.

Statistical analysis was undertaken on the composited drill hole file to determine the domain boundaries with appropriate variogram applied. The domains resources were calculated using ordinary kriging (“OK”) with variable orientation estimation methodology. A total of the nearest 20 samples were used to determine grade. Mineralisation was modelled as three-dimensional blocks of primary size:

  • 5 m Vertical

  • 5 m Horizontal

  • 1 m Width

This block size reflects the narrow high-grade vein nature to the mineralization that have both extension lateral and depth extents. The mineralization in this resource extends for greater than 1.2km in strike and at least 7 vein packages (>10 veins per set) are recorded in the drilling with the package names as follows

Iolanthe, Bluff, Wayback, Johnson, Dazzler, Talis & Crown lodes. Several historical names are part of these larger packages (e.g. Nel, Nil, Ruby etc.).

Each of these vein packages has several king veins where high grades of tungsten are recorded and in some cases (e.g. Bluff) contain more than 20 individual quartz tungsten veins.

In depth constraints the southern lodes of Iolanthe, Bluff, Wayback and to some extent Johnson have shown to be cut-off by the South Wall Fault which is a major Reverse Slip Fault (Nick Oliver, report comm.) on the southern extent of the deposit. The remaining vein packages show depth extents of over 400m vertically with no sign of truncation.

In global sense from the drilling two high-grade zones are known with the primary zone being a vertical zone that extends below the historical pit and a second zone to the west that appears to plunge westward to depth. Both these high-grade zones have extensive zones of veins that exceed 1m @ 1% WO3 and in recent drilling have extended up to 18.24m @ 1.0% WO3 (Hole EQ030, depth from 387.25 to 405.49m).

Mining & Environmental Factors

Completion of two Bankable Feasibility Studies (See EQ Resources website ‘Technical Reports Mt Carbine Expansion Project – Bankable Feasibility Study dated 31 December 2021 & Mt Carbine Expansion Project – Bankable Feasibility Study 2022 dated 09 November, 2022) demonstrate the economics of the project and viability to include the current cut-offs for this MRE. The success of mining the 0.075% WO3 dumps has demonstrated the viability of even low grades in current mining conditions. A more conservative approach with the costs of open pit mining have suggested that grades between 0.05% and 0.08% WO3 be stockpiled as low grade ore for later tungsten extraction and all mineralisation above 0.08% WO3 be sent direct to ROM. The latest BFS completed by EQ Resources did a major adjustment for fuel prices, labour price increases and used actual contract mining rates and discounted tungsten pricing.

EQR has been granted an Environmental Authority by the Queensland Department of Environment and Science (“DES”) for both the Low-Grade Stockpile and for operations in the In-Situ Open Pit Development. All permits exist for commencement of the mining activities at the Mt Carbine site.

APPENDIX A: JORC TABLE 1 – INSITU OREBODY

Section 1 - Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections)

Criteria JORC Code Explanation Details
Sampling
techniques
Nature and quality of sampling (e.g.- 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 (e.g.- ‘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
(e.g.-
submarine nodules) may warrant disclosure of
detailed information.
All zones of potential mineralisation were logged and sampled by cutting the core interval selected in half and
the complete half core was sent to ALS Laboratories in Brisbane Australia for analysis.
Before cutting and sampling the core is logged with zones of visual minerals of wolframite and scheelite
recorded by their percentages. scheelite glows under ultraviolet light and although difficult to distinguish
under ordinary light from quartz-carbonate it is visual under the shortwave 254nm UV light with a common
technique to estimate grade being to trace out individual crystals and determine the overall percentage
shown on the face of the core. Often the mineralisation is manifested as very coarse tungsten mineral
crystals of up to 10cm in size.
The method used for the analysis of Tungsten was ME-XRF15b where the sample was fused into a disk in a
furnace and then analysed by a Bruker X-ray Fluorescent machine. ALS is a registered laboratory that
conducts internal and external round-robin analysis to maintain its certification and to ensure that the
machine used for analysis is correctly calibrated. The Assaying is completed at 10ppm accuracy, It is
important in this process that the sample is homogenous, and as such the sample is prepared by crushing
and grinding to less than 200 microns to ensure homogeneity.
All quartz veins intersected in the drilling have been assayed as separate samples. Where the veins are more
than 1m in downhole length then the sample is broken into two or more samples each with a maximum of
1m intervals. The minimum vein assayed is 5cm in width. Since the mineralisation at Mt Carbine often
occurs in narrow widths of 5-500cm then it is important to assay each such narrow zones. On either side of
the mineralised zone, samples are also taken of the host rock at intervals of 1m to ascertain if the
mineralisation has extended into the host rocks.
Drilling at Mt Carbine was completed by HQ and NQ sized diamond drilling rig that used both double and triple
tube-drilling techniques, HQ was drilled down until the South Wall Fault was intersected and then cased off
before continuing in NQ drill size. The footwall of this fault has no mineralisation as noted under the geology
section and this fault truncates all observed mineralisation. The full core is being collected and marked for
its depth and orientation. The core was drilled using a digital orientation method and the Reflex Act III tool
system. Recording hole orientation and hole survey that is wirelessly transmitted to back-end computer for
recording.

Criteria JORC Code Explanation Details
Drilling
techniques
Drill type (e.g.- core, reverse circulation, 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).
Drilling at Mt Carbine was completed by HQ and NQ sized diamond drilling rig that used both double and triple
tube-drilling techniques, HQ was drilled down until the South Wall Fault was intersected and then cased off
before continuing in NQ drill size. The footwall of this fault has no mineralisation as noted under the geology

its depth and orientation. The core was drilled using a digital orientation method and the Reflex Act III tool
system. Recording hole orientation and hole survey that is wirelessly transmitted to back-end computer for
recording.
Drill
sample
recovery
Method of recording and assessing core and chip sample
recoveries and results assessed.
Measures taken to maximise sample recovery and ensure
representative nature of the samples.
Whether a relationship exists between sample recovery and
grade and whether sample bias may have occurred due
to preferential loss/gain of fine/coarse material.
Core was marked with core blocks typically at 1.5 & 3.0m intervals by the drilling company using stick-up
techniques that ensure measurement to 1cm accuracy.
The core showed very high recoveries with 99% recovered on the entire campaign to date. With the extreme
hardness of the quartz zones, no loss from drilling has been recorded to date, nevertheless, each interval
is measured to ensure this is the case. The core is hard and competent and all sampling in this programme
is below the base of oxidation. Host rocks are metasediments that have been silicified and then crosscut
by sheeted white quartz veins.
Logging Whether core and chip samples have been geologically and
geotechnically logged to a level of detail to support
appropriate Mineral Resource estimation, mining studies
and metallurgical studies.
Whether logging is qualitative or quantitative in nature. Core
(or costean, channel, etc) photography.
The total length and percentage of the relevant intersections
logged.
The core has been re-joined into long sticks and photographed using a high-resolution camera for both dry
and wet images. The core has a geotechnical log completed and core marked up and measured for
recovery etc. Using the marks provided during the drilling an orientation line is marked down the full length
of the core. Post sampling, the core has been selected for alteration mapping and petrographic studies but
has yet to be sent to the relevant consultancy.
Logging is quantitative in its description of alteration intensity, and mineral types in percentages using
geological percentage charts.
Sub-sampling
techniques and
sample
preparation
If core, whether cut or sawn and whether quarter, half or all
core taken.
If non-core, whether riffled, tube sampled, rotary split, etc and
whether sampled wet or dry.
For all sample types, the nature, quality and appropriateness
of the sample preparation technique.
Quality control procedures adopted for all sub-sampling
stages to maximise representivity of samples.
Measures taken to ensure that the sampling is representative
of the in situ material collected, including for instance
results for field duplicate/second-half sampling.
Whether sample sizes are appropriate to the grain size of the
material being sampled.
The core is cut in half using a diamond saw along the centre line marked referred above being the mark for the
orientation of the core. Half core was used in all sampling collections.
Each sample was weighed and marked correctly in consecutive order with a space left for the insertion of
standards and this was done every 10th sample for 10% checks and balances. No samples were combined
for assay with each sample assayed separately and are either a vein or host rock.
EQR completed a comprehensive assessment of past core including duplicates and repeats to establish that
the ALS assaying shows consistency and accuracy and historical results were accurate. EQR inputs 10%
of the samples sent to the laboratory as either a blank or predetermined assay standard. With each batch
of results sent there is a minimum of 5 check samples inserted.

Criteria JORC Code Explanation Details
Quality of assay
data
and
laboratory tests
The nature, quality and appropriateness of the assaying and
laboratory procedures used and whether the technique is
considered partial or total.
For geophysical tools, spectrometers, handheld XRF
instruments, etc, the parameters used in determining the
analysis including instrument make and model, reading
times, calibrations factors applied and their derivation,
etc.
Nature of quality control procedures adopted (e.g.-
standards,
blanks,
duplicates,
external
laboratory
checks) and whether acceptable levels of accuracy (i.e.
lack of bias) and precision have been established.
Tungsten best corresponds to X-ray Fluorescence assay techniques and the best of these techniques uses a
fusion disk where a representative sample of the core is taken after fine grinding until a homogenous sample
is obtained (<200 microns) and then melted in an arc furnace to produce a clear fused disc. This disk is
then x rayed with the fluorescence recorded by way of spectral peaks. The machine needs to be calibrated
to record quantitative results. The instrument is a Bruker multi-shot XRF machine with an X-ray scan of 1
minute applied to each disk to get the light and heavy elements.
All checks are also assayed in each batch in their order with 10% check samples submitted alternatively being
either a blank, a tungsten standard or a repeat sample with a known grade. Precision is 10 ppm for this
technique with our samples noted as being significant above 1000 ppm. Only in one instance, the results
do not match the visual in sample no. 100216 and 100217, which are vein and host rock. By the weights of
each of these samples, it was determined that the grade of 0.72% was in the vein, not the host rock i.e.
samples at the lab have been switched.
Verification
of
sampling
The verification of significant intersections by either
independent or alternative company 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.
Each mineralised interval is recorded by the Site Resource geologist and then checked for accuracy by the
company’s chief geologist before cutting and sampling occur.
No twinned holes have been completed in this programme
Data is completed using a paper log sheet with the information and then transferred to a digital database
holding all the information on drilling, surveying, assays, recovery, Geotech info etc.
No uppercuts were applied in reporting exploration results and only results where an individual assay was
taken are used. No partial intervals or subsets were used.
Drill intervals quoted are down-hole intervals as the true widths will only be determined once the accurate
orientation of the veins occurs.
Location of data
points
Accuracy and quality of surveys used to locate drill holes
(collar and down-hole surveys), trenches, mine workings
and other locations used in Mineral Resource estimation.
Specification of the grid system used.
Quality and adequacy of topographic control.
Surveying of the drill holes was completed using a Garmin GPS61 model GPS for locating the collar
coordinates in the WGS84 Datum system. Downhole surveys were conducted every 30 m down the hole
except for the pre-collar zones. These zones reached up to 120 m in depth with HW casing being installed
before continuing drilling in NQ-sized core. All survey data were input into the database and then plotted
using Leapfrog Mining Software to determine any swings in the hole.
Topography has 2020 been upgraded to 10 cm accuracy using a LIDAR Drone survey technology with the
topography having high-resolution photography overlaid.
Holes were in July surveyed by Differential GPS against known trig stations and converted to local grids by
professional surveyor Neil Murphy who was Project Manager from Brazier Motti Pty Ltd based in Cairns,
North Queensland.
Data
spacing
and distribution
Data spacing for reporting of Exploration Results.
Whether the data spacing and distribution is sufficient to
establish the degree of geological and grade continuity
appropriate for the Mineral Resource and Ore Reserve
estimation procedure(s) and classifications applied.
Whether sample compositing has been applied.
Drilling Is currently designed to complete the testing of the zone beneath the historical pit at a spacing of 30 x
30m and 50 x 50m centres.
In several locations, drilling spacing was completed down to 20m to provide additional data and confirm the
grade and widths of zones etc.

Criteria JORC Code Explanation Details
Sampling compositing has occurred in the reporting of results of this press release using weighted averages
for the assay result and a total distance for the length of the geological interval.
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 orientation and the
orientation of key mineralised structures is considered to
have introduced a sampling bias, this should be assessed
and reported if material.
The drilling was done at right angles to the trend of the mineralisation on a localized grid that has been used
since the 1960s and this local grid has been used to orientate all 89 drill holes completed on the property.
This allows for regular spacing and interpretations of the deposit veins.
Depending on the hole angle and attitude of the vein the released results which are down-hole intervals will
report a longer interval than the true width of the vein. No bias has been determined for the mineralisation
as the mineralised veins show remarkable parallel zones and it is deemed that the drilling has been
completed at the best angle to give a true indication of the zones.
Sample
security
The measures taken to ensure sample security. The core is transported daily to a fenced core shed yard. This yard remains locked after work hours and
contains a roofed shed within which core racks are installed the house the core. On a more permanent
basis, each hole is cling-wrapped and put on a separate pallet and put in its number place at the core farm.
All samples are taken and bagged and placed in this locked enclosure in larger 1-tonne bags. Rejects from the
sampling are also stored should a check is required or further element analysis is needed. The larger bags
are inspected on arrival at ALS to ensure no tampering has occurred to the samples.
Audits
or
reviews
The results of any audits or reviews of sampling techniques
and data.
An internal audit of techniques was completed to check for any sample bias or variances being introduced to
the samples. No biases were encountered.

About this drilling, all historical holes with their intersections compiled using the same criteria as current drilling
have been reported previously (High-grade structural zones extend for 1.2 km: Mt Carbine historical drilling
reinterpretation – 16th October 2020) have been recorded on all sections and plans and this has been
completed by various companies over the past 25 years.
Geology Deposit type, geological setting and style of mineralisation. The deposit falls into the sheeted hydrothermal tungsten vein style that is associated with the Mareeba
Granodiorite. The veins are narrow from 5 to 500 cm in width and extend for up to 1.2 km along strike as
currently understood. They have been drilled over a 400 m vertical extent and occur in groups designated
as zones and referred to as Iolanthe, Bluff, Wayback, Johnson, Dazzler and Iron Duke. The veins with
higher grade mineralisation occur as late veins and overprints on an extensive early vein system that has
weaker tungsten mineralisation or no mineralisation. This late overprint is what EQR is chasing in the
current drill programme.

Data
aggregation
methods
In reporting Exploration Results, weighting averaging
techniques, maximum and/or minimum grade truncations
(e.g.- cutting of high grades) and cut-off grades are
usually Material and should be stated.
Where aggregate intercepts incorporate short lengths of
high-grade results and longer lengths of low-grade
results, the procedure used for such aggregation should
be stated and some typical examples of such
aggregations should be shown in detail.
The assumptions used for any reporting of metal equivalent
values should be clearly stated.
Weighted averages are used for any results combined with no uppercuts applied. A zone reported may contain
results with no grade provided it is the same zone used on other sections, to maintain geological uniformity
between the sections.
Domain 1 – is identified by the closer spacing of the King Veins allowing for larger composites of the zones to
be made. The resource uses composites made up above 0.05% WO3to identify the boundaries of the
zones including up to 10 m of internal waste. The shapes were drawn in sections and confirmed to match
the geology and then wire framed as a hard boundary to the mineralized zones. Block modelling was done
inside the geological wire frames using a variogram search that matches the veins' orientations, dip and
strike. The block model was then validated against the sections to confirm grade distribution reflects the
intersected grade and location of intervals.
Domain 2 - Only those zones where the combined metal factor being the ‘grade x interval’ is above 2 m
@0.25% * i.e. a metal factor of 0.5) Tungsten Trioxide (WO3) are reported as being significant in this
release. e.g. 0.3 @ 8.0% WO3has a metal factor of 2.4 and qualifies but 4m @ 0.1% with metal factor of
0.4 does not qualify.
Relationship
between
mineralisation
widths and
intercept length
These relationships are particularly important in the reporting
of Exploration Results.
If the geometry of the mineralisation with respect to the drill
hole angle is known, its nature should be reported.
If it is not known and only the downhole lengths are reported,
there should be a clear statement to this effect (e.g.-
‘down hole length, true width not known’).
The results reported are downhole intercepts and not true widths. Although all drilling has been completed at
right angles to the strike of the veins, the holes may intercept the vein at an angle given that the veins
generally are from 60-90 degrees in dip. To determine true width requires the individual veins to be
orientated in space and the surveyed hole to also be known at that point.
For orientation, all veins are being measured for both Alpha and Beta angels to enable the absolute dip and
direction of each vein to be determined in the orientated core. The veins do vary in their strike and dip and
until the orientations have been entered into the database along with the surveyed hole angles, and run
through the leapfrog mining software true widths are not known. Interception true widths may vary from
being 0.3 of the downhole interval to no change to the downhole intervals. The point of interception of the
vein and the attitude of the hole at this point determines the true width and this calculation has not been
done. It should also be noted that in quite a few instances the angles of the same vein vary significantly on
either margin. In these instances, true width will be calculated on the average dip and strike When any
resources will be calculated in the future only true width intervals will be used.
Diagrams Appropriate maps and sections (with scales) and tabulations
of intercepts should be included for any significant
discovery being reported. These should include, but not
be limited to a plan view of drill hole collar locations and
appropriate sectional views.
A local grid is used in the drilling to ensure the drilling has been completed at right angles to the strike of the
mineralisation. The local grid is at a 51-degree rotation westwards to true north; i.e.
Local Grid North-South is aligned at 51 degrees against true north with a yearly deviation occurring as the
continents drift.
Balanced
reporting
Where comprehensive reporting of all Exploration Results is
not practicable, representative reporting of both low and
high grades and/or widths should be practiced to avoid
misleading reporting of Exploration Results.
All zones that meet the criteria of significance as defined above have been recorded and shown on the
associated cross-sections. Where there is a blank it means no results met the criteria used as significant
results. At this point, only the data is represented with the most recent geological interpretation, but no
resource association is implied with the release of these results.
The zones on each section refer only to the results being released for the current hole and the results of
adjacent old holes are not included as this is not new information.

data
Other exploration data, if meaningful and material, should be
reported including (but not limited to): geological
observations; geophysical survey results; geochemical
survey results; bulk samples – size and method of
treatment; metallurgical test results; bulk density,
groundwater, geotechnical and rock characteristics;
potential deleterious or contaminating substances.
The mineralisation occurs as narrow late quartz veins overprinting an earlier phase of quartz veining that
reaches up to 30% of the zones marked on the sections. Although all quartz veins are sampled to be
complete, most are from the earlier event that has no mineralisation associated with it. The interpretation
is cantered on those veins that do carry tungsten and what is perceived as the controls to these zones.
More than 100 bulk densities have been completed at the project and the host rock and mineralised zones
record bulk densities of 2.6 and 2.8 respectively with 2.74 as the average bulk density
The South Wall Fault marked on the maps has truncated much of the veining as shown on the sections. The
current interpretation of this fault is that is a reverse thrust fault with the footwall dropping an unknown
distance.
Further work The nature and scale of planned further work (e.g.- tests for
lateral extensions or depth extensions or large-scale
step-out drilling).
Diagrams clearly highlighting the areas of possible
extensions, including the main geological interpretations
and future drilling areas, provided this information is not
commercially sensitive.
The company continues to drill to outline the limits of the mineralisation in both strike and depth constraints.
The target is limited to what might be considered in an open-cut extension of the pit but several holes were
extended to look at the potential of additional veins such as Iron Duke for a future underground operation.

Criteria JORC Code Explanation Details
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.
The specific measures taken by previous parties to ensure database integrity are not known but
the creation of a digital database has allowed for ongoing review of the integrity of the data.
EQR maintains a database that contains all drill hole surveys, drilling details, lithological data and
assay results. Where possible, all original geological logs, hole collar survey files, digital
laboratory data and reports and other similar source data are maintained by EQR. The
database is the primary source for all such information and was used by the Competent Person
to estimate resources.
The Competent Person undertook consistency checks between the database and original data
sources as well as routine internal checks of database validity including spot checks and the
use of validation tools. No material inconsistencies were identified.
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.
The Competent Person, Mr Tony Bainbridge works full time at the Mt Carbine Tungsten Project in
North Queensland, Australia since February 2020. Mr Bainbridge is in principal position to plan
and execute the drill programs that this resource is based upon and has verified all the historic
drill hole collars in the field, inspected the drill core, reviewed the metallurgical and
mineralogical test work that was previously completed, and reviewed the extensive geological
database.
Mr Bainbridge has developed the protocols and procedures for all QAQC work and routinely
checks the database for accuracy. Mr Bainbridge has developed the exploration models for the
site that have proved to be successful with a large increase in high grade mineralisation being the
outcome.
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.
Geological setting and mineralisation controls of the Mt Carbine Project mineralisation have been
confidently established from drill hole logging and geological mapping, including the
development of a robust three-dimensional model of the major rock units.
The geological domains are based on a minimum 2 m downhole depth of mineralisation. The
composited grades are based on sampled, assayed results and barren zones to create a zone
of mineralisation for geological modelling and resource estimation based on these composited
grades.
Due to the confidence in the understanding of mineralisation controls and the robustness of the
geological model, investigation of alternative interpretations is unnecessary.
Dimensions The extent and variability of the Mineral Resource expressed
as length (along strike or otherwise), plan width, and
Drilling indicates that the mineralisation continues up to 1300 m along strike and up to 600 m wide.

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

Any assumptions behind modelling of selective mining units.
Any assumptions about correlation between variables.
Description of how the geological interpretation was used to
control the resource estimates.
Discussion of basis for using or not using grade cutting or
capping.
The process of validation, the checking process used, the
comparison of model data to drill hole data, and use of
reconciliation data if available.
Statistical analysis was undertaken on the composited drill hole file to assess the appropriateness
of the domaining process and as such, no additional domaining was undertaken. All domains
were interpolated using ordinary kriging (“OK”).
A strike of vein packages was determined by surface mapping and use of oriented core directions
to apply a Variable Orientation Estimate to the variography so each vein was extended based
on factual data. The block search was limited to a estimate from the first 20 samples reached
using the local variogram conditions.
Mineralisation was modelled as three-dimensional blocks of size 5 m X 5m X 5 m. No sub-blocks
were used on the modelling.
No assumptions were made regarding the modelling of selective mining units.
Validation of the block model was made by:
checking that drill holes used for the estimation plotted in expected positions;
checking that flagged domains intersections lay within, and corresponded with, domain
wireframes;
ensuring whether statistical analyses indicated that grade cutting was required;
checking that the volumes of the wireframes of domains matched the volumes of blocks of domains
in the block model;
checking plots of the grades in the block model against plots of drill holes;
Historical estimates were examined and the comparisons were similar yet inconclusive due to the
‘discreet’ style of geological interpretation in this estimate compared to the larger, all-
encompassing lower grade style previously.
Moisture Whether the tonnages are estimated on a dry basis or with
natural moisture, and the method of determination of the
moisture content.
Tonnages were estimated on a dry basis.
Cut-off
parameters
The basis of the adopted cut-off grade(s) or quality
parameters applied.
The mineralised material is interpreted to have ‘reasonable prospects of eventual economic
extraction’ by open-pit methods and by underground mining methods.
No upper cut-off grades were applied to the Mt Carbine Resource Estimate. The competent person
establish to their satisfaction that the high-grade zones recorded in the drill results were present
in the mineralized zones and could be linked between sections to our satisfaction.
Domain 1 - A lower cut of 0.05% WO3was used in Domain 1 to reflect the wider zones that include
lower-grade mineralisation halos. It was found that it was not practical to apply a similar cut to

Criteria JORC Code Explanation Details
other areas of the deposit where the veins themselves are more isolated and are treated as
single zones. An upper cut at 10% was applied to the data set for individual assays to match
the statistical curve grade–frequency variances. This subset domain was to identify material to
be put on the LGS dump as our marginal low grade dump material.
Domain 2 – A lower cut of 0.08% WO3- Above this cut-off grade was used to determine the
resource and definition of the geological boundaries to the mineralized zones as per the
statement that will be mined as potential ROM Feed. Included in the resource statement is a
tonne-by-grade table that highlights how cut-off grade variations influenced the tonnages.
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 resource estimate has been completed with the assumption that it will be mined using open
cut and underground mining methods. No other detailed assumptions have been made to date.
However, EQR will be completing a Feasibility Study on this resource estimate model, and

The resource estimate has been completed with the assumption that it will be mined using open

This showed that in the open-cut scenario the deposit was economic using a 0.08% Composite
criteria on the wire-framed geological results.
Mining Trials have continued on the LGS dump showing that excellent efficiencies are presently
using the Tomra ore sorting such that grades from 0.05% WO3are economic to mine. This has
led to looking at a rerun of the block model at a lower cut-off for the pit. Low-grade halo ore from
the pit will be put onto an LGS Rom pad and evaluated monthly for its economics at the relevant
tungsten price.
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.
Historical production shows the Mt Carbine Project was in the lowest quartile cost of production of
western producers and produce very high-grade wolframite (>70% WO3) and scheelite (68-
72%WO3) concentrates with no or very low impurity penalties.
The main processes involve crushing to several different product sizes and then screening to
create the product.
These processes are in current production and lead to the ‘reasonable prospects for eventual
economic extraction’ considered by the Competent Person.
Environmental
factors
or
assumptions
Assumptions made regarding possible waste and process
residue disposal options. It is always necessary as part of
the process of determining reasonable prospects for
eventual economic extraction to consider the potential
environmental impacts of the mining and processing
operation. While at this stage the determination of
potential environmental impacts, particularly for a
Greenfields project, may not always be well advanced,
There has been recorded mining activity at the Mt Carbine Project between 1974-1987.
There is currently re-processing of low-grade ore from the stockpile constructed from the discarded
material and existing tailings dam.
Near the project site, the land is mainly used for forestry, livestock farming and recreational
activities.

Criteria JORC Code Explanation Details
the status of early consideration of these potential
environmental impacts should be reported. Where these
aspects have not been considered this should be
reported with an explanation of the environmental
assumptions made.
As the potential mine area contained an active open-pit mine up until 1987; and is still by law
considered an active Mining Licence Area, development near the deposit has been limited.
A surface water sampling programme (now in place for two years) for environmental monitoring.
Completion of 5 twinned water monitoring bores to aid monitoring of groundwater regimes for
environmental management.
Development of an application for a higher level of Environmental Approval to cover the mining
activities and processing.
Bulk density Whether assumed or determined. If assumed, the basis for
the assumptions. If determined, 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 (i.e.
vugs, porosity, etc), moisture and differences between
rock and alteration zones within the deposit.
Discuss assumptions for bulk density estimates used in the
evaluation process of the different materials.
A total of 1,048 density measurements from the drill core were completed.
The methodology of density measurements was as follows:
A length of solid and intact/unbroken core with essentially zero porosity was selected and the ends
were carefully cut with a diamond saw to make a near-perfect cylinder.
The core was then sun-dried and the length and diameter of the cylinder (average of three readings
with callipers) and an accurate weight were recorded to permit a simple volume/dry weight
density estimate.
Density measurements were analysed for any spatial trends by easting, northing and depth, with
no obvious trends detected.
Hence, an average density of 2.74 was applied to the whole deposit.
Classification The basis for the classification of the Mineral Resources into
varying confidence categories.
Whether appropriate account has been taken of all relevant
factors (i.e. relative confidence in tonnage/grade
estimations, reliability of input data, confidence in
continuity of geology and metal values, quality, quantity
and distribution of the data).
Whether the result appropriately reflects the Competent
Person’s view of the deposit.
Classification of the Mineral Resource estimate was interpreted on several criteria, including
confidence in the geological interpretation, the integrity of the data, the spatial continuity of the
mineralisation and the quality of the estimation.
An assessment of the historical mining showed increased confidence in the surrounding areas of
the open-cut and confirmed by drilling results.
The classification reflected the author’s confidence in the location, quantity, grade, geological
characteristics and continuity of the Mineral Resources.
The data spacing and distribution are sufficient to establish geological and grade continuity
appropriate for Mineral Resource estimation and classification and the results appropriately
reflect the Competent Person’s view of the deposit.
Audits
or
reviews
The results of any audits or reviews of Mineral Resource
estimates.
An internal audit of techniques was completed to check for any bias or variances being introduced
to the resource estimate. No biases were encountered.

Discussion
of
relative
accuracy/
confidence
Where appropriate a statement of the relative accuracy and
confidence level in the Mineral Resource estimate using
an approach or procedure deemed appropriate by the
Competent Person. For example, the application of
statistical or geostatistical procedures to quantify the
relative accuracy of the resource within stated confidence
limits, or, if such an approach is not deemed appropriate,
a qualitative discussion of the factors that could affect the
relative accuracy and confidence of the estimate.
The statement should specify whether it relates to global or
local estimates, and, if local, state the relevant tonnages,
which should be relevant to technical and economic
evaluation. Documentation should include assumptions
made and the procedures used.
These statements of relative accuracy and confidence of the
estimate should be compared with production data,
where available.
The estimates made for this report are global estimates. Predicted tonnages and grades made
from such block estimates are useful for feasibility studies, and long-, medium- and short-term
mine planning. Individual, as distinct from aggregated, block estimates should not be relied
upon for block selection for mining.
Local block model estimates, or grade control estimates, whose block grades are to be relied upon
for the selection of ore from waste at the time of mining will require additional drilling and
sampling of blast holes.
Confidence in the relative accuracy of the estimates is reflected in the classification of estimates
as Indicated and Inferred.
Variography was completed for Tungsten. The variogram models were interpreted as being
isotropic in the plane with shorter ranges perpendicular to the plane of maximum continuity.
Validation checks have been completed on raw data, composited data, model data and Resource
estimates.
The model is checked to ensure it honours the validated data and no obvious anomalies exist
which are not geologically sound.
The mineralised zones are based on actual intersections. These intersections are checked against
the drill hole data. The Competent Person has independently checked laboratory sample data.
The picks are sound and suitable to be used in the modelling and estimation process.
Further drilling also needs to be completed to improve the Resource classification of the Inferred
Resource.

The Deposit
The Mt Carbine tungsten deposit is a sheeted quartz vein deposit. Many sub-parallel, sub-vertical
quartz veins have been deposited in fractures developed in the host rocks metasediments in a
zone that drilling and mapping of historical surface workings have shown to be approximately 300m
wide and at least 1.4 km long, trending at about 315 degrees.
Grade Variation
Sampling, drill core logging, geostatistical analysis of drill core assay data and mapping of the open
pit have determined that all the material mined during the previous operation was mineralised to
some extent and that the mineralogy of the deposit was uniform. There is little doubt that the
mineralogy of the stockpile material is identical to that mined and processed. The material in the
stockpile comprises a single formation, the result of the alteration of Siluro-Devonian meta-
sedimentary host rocks (Forsythe and Higgins, 1990).
The amount of quartz veining varies within the mineralised zone and previous mining and exploration
have been concentrated at the south-eastern end of the mineralised zone. It is well understood
that there are high-grade zones within the mineralisation in this part of the deposit and that the
higher-grade zones are surrounded by lower-grade mineralisation. Interpretation of recent drilling
suggests that the main high-grade zone may plunge to the north of the present open pit. The
previous mine assumption that quartz vein abundance is directly correlated with grade is not
supported by an independent review of quartz vein abundance and grade.

Nature of the data used and of any assumptions

The effect, if any, of alternative interpretations on

Mr Dean Krak is the resource geologist and who is extensively involved in sampling, logging, photography
survey and other geological duties. Mr Krak has six years experience in resource work and modelling.
Dimensions The extent and variability of the Mineral Resource
expressed as length (along strike or otherwise),
plan width, and depth below surface to the
upper and lower limits of the Mineral Resource.
The 10.126Mt tonnes estimated to be remaining in the LGS have been mined on trial continuously for 18 months
and the grade and recovery confirms the head grade is 0.075% as determined in resource work. Good mass
balances are achieved throught this mining.

In the case of block model interpolation, the block
size in relation to the average sample spacing
and the search employed.
Any assumptions behind modelling of selective
miningunits.
The detailed distribution of grade through the LGS is not known, as no record was kept of placement of rock
consigned to the stockpile, nor was any sampling carried out. The average of assays of the three-size range
subsamples of the bulk sample is 0.075% WO3. This reconciles very favourably with a back-calculation from
historic mine records of production and mill recovery and based on the recent resource estimate which took
account of the resource mined during the previous open pit operation, of a global average grade of 0.075%
WO3for the Low-Grade Stockpile.
It should be noted that the historical mine records state that 3.5Mt of rock described as ore was consigned to
the stockpile in 1982.
The grab samples average 0.088% WO3(fused disk XRF analysis), which is taken to indicate that the tungsten
grade of the finer fraction (<200mm) of the stockpile is higher than the global average grade of the bulk
sample that included fragments up to 500mm.

Criteria Explanation Commentary
explanation of the basis of the metallurgical
assumptions made.
Environmental
factors or
assumptions
Assumptions made regarding possible waste and
process residue disposal options. It is always
necessary as part of the process of determining
reasonable prospects for eventual economic
extraction
to
consider
the
potential
environmental impacts of the mining and
processing operation. While at this stage the
determination
of
potential
environmental
impacts, particularly for a greenfields project,
may not always be well advanced, the status of
early
consideration
of
these
potential
environmental impacts should be reported.
Where these aspects have not been considered
this should be reported with an explanation of
the environmental assumptions made.
EQR has been granted an Environmental Authority by the Queensland Department of Environment and Science
(“DES”) for the Low-Grade Stockpile. Based on the sampling of existing stockpiles, tailings storage facilities
and analytical characterisation of the mineralisation, the only elements present at hazardous values are
fluorine (as fluorite) and arsenic (as arsenopyrite). Previous mine practice and the present Environmental
Management Plan approved by the DES include measures to manage the environmental hazards these
elements present. The sampling of the existing stockpiles and tailings storage facility indicates that acid mine
drainage will not be a hazard created by future mining and waste storage.
Bulk density Whether assumed or determined. If assumed, the
basis for the assumptions. If determined, 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 and alteration
zones within the deposit.
Discuss assumptions for bulk density estimates
used in the evaluation process of the different
materials.
The tonnes estimated to be contained in the stockpile have been derived independently of calculation by
multiplying volume by density.
Classification The basis for the classification of the Mineral
Resources into varying confidence categories.
Whether appropriate account has been taken of all
relevant factors (i.e. relative confidence in
tonnage/grade estimations, reliability of input
data, confidence in continuity of geology and
metal values, quality, quantity and distribution
of the data).
Whether the result appropriately reflects the
Competent Person’s view of the deposit.
Following extensive metallurgical testing of bulk samples from the stockpile that provide robust anticipated
recovery and quality of product, the LGS has been classified as an Indicated Resource.

Audits or
reviews.
The results of any audits or reviews of Mineral
Resource estimates.
The estimates for the LGS have been subject to internal Company and Independent Competent Persons
Company review.
Discussion of
relative
accuracy/
confidence
Where appropriate a statement of the relative
accuracy and confidence level in the Mineral
Resource estimate using an approach or
procedure
deemed
appropriate
by
the
Competent
Person.
For
example,
the
application
of
statistical
or
geostatistical
procedures to quantify the relative accuracy of
the resource within stated confidence limits, or,
if such an approach is not deemed appropriate,
a qualitative discussion of the factors that could
affect the relative accuracy and confidence of
the estimate.
The statement should specify whether it relates to
global or local estimates, and, if local, state the
relevant tonnages, which should be relevant to
technical
and
economic
evaluation.
Documentation should include assumptions
made and the procedures used.
These
statements
of
relative
accuracy
and
confidence of the estimate should be compared
withproduction data,where available.
The success of the proposed stockpile treatment is underpinned by the fact that the same orebody was profitably
mined for 13 years by the previous operators. The mine only closed in 1987 because of the price collapse
caused by oversupply from Chinese producers dumping products on the market, resulting in the closure of
most western tungsten-producing mines. Before the price collapse, the Mt Carbine mine operators and their
joint venture partners had carried out detailed plans to extend the mine life and maintain production for a
further ten years.
The Mt Carbine mine had not run out of ore (there was an estimated 3.5Mt of ore to be extracted from the
existing pit before any mine expansion had to be considered). The ore treatment process was well
documented, and studies spurred by the collapsing price showed that mill recovery could be significantly
increased. This has since been confirmed by test work carried out by EQR.
