The classification for the Panther deposit has been defined by the increased geological understanding from

recent RC drilling and the confidence in the continuity of mineralising features. Figure 2 below shows the

classification of the updated MRE in long section view.

PANTHER RC DRILLING – PHASE 3

Beacon is pleased to provide the results of its third phase of resource definition drilling at the Company’s

Panther Prospect. A total of 20 holes were drilled for 1,308 metres (Appendix 1).

The program was drilled in May 2020 and followed up the first and second phases of drilling, attempting to

close off shallow mineralisation identified in the earlier programs.

This new drilling was used in conjunction with recent and historical drilling to develop the updated MRE.

Significant intersections of mineralisation confirmed existing trends and extended known mineralisation at

depth, see Figure 3.

Significant intercepts include:

Pursuant to listing Rule 5.8.1, and in addition to the information in the JORC Tables in Appendix 1, Beacon

provides a summary of the Panther Mineral Resource Estimate (MRE).

Panther Mineral Resource Overview

The MRE was undertaken by independent resource consultants BM Geological Services Pty Ltd (BMGS).

The MRE was updated from October 2019 announcement using an additional 125 RC holes for 7,700 metres

of drilling completed by Beacon to improve the understanding of the deposit. The tonnes and grade were

generated using a gold top‐cut of 25g/t and a lower reporting gold cut off of 0.6g/t.

Geology

The primary ore lode at the Panther deposit is striking NW‐SE, varyingly steep dipping 70°W shear zone, with a large scaled quartz vein stockwork associated with the gold mineralisation. A weathered profile exposed in Panther pit shows an upper saprolite and lower saprolite lithology suite including a high‐magnesium basalt or ultramafic pyroxenite (multi‐element to confirm) in proximity to basalt host rock

The quartz veining stockwork is made up of vein sets regularly spaced approximately 5m apart, with horizontal and vertical sets ranging in thickness from 5cm to 40cm. The majority of mapped veins in the Panther pit are of 20‐25cm thick on the footwall side of the shear and in proximity to the main NW‐SE shear


zone. The quartz veins deeper in pit are of increasing thickness, up to 40cm. Two other notable but smaller shear zones intersect the main shear zone entering from the west side of Panther pit.

A flat lying supergene enrichment zone is interpreted for both Northern and Southern extremities, where the Panther shear extends to surface. The supergene mineralisation varies in thickness between 1 and 6m.

Drilling and Data Collection

For the Panther 2020 MRE 222 RC holes (for 14,066m) and 2 diamond holes (for 140m) were used.

Validation checks were carried out on collar locations, downhole surveys and overlapping samples.

No AC, RAB or historical grade control drilling was used in the updated MRE.

For RC drilling, a face sampling hammer was used generating 1m samples. Samples were collected through

a rig mounted cone or riffle splitter. Diamond core samples were cut with a diamond blade, with half the

core being sent for analysis. Beacon completed QAQC monitoring for the sampling and assaying including

regular field duplicates, standards and blanks. Assays are monitored for repeatability and accuracy of

standards. All gold assaying is undertaken at reputable labs using industry standard practices and

procedures. All samples were assayed using 40g or 50g charge lead collection Fire Assay with atomic

absorption spectrometry finish (AAS finish).

All recent drillhole collars completed by Beacon and Sentosa Mining were surveyed using differential global

positioning systems (DGPS) tool. Downhole surveys were carried out for all the RC and diamond drilling on

5m intervals.

Model & Estimation

The Panther mineralisation consists of a NW‐SE trending package with a westerly dip. The deposit was

estimated using Ordinary Kriging (OK) grade interpolation of 2m composited data. A Surpac block model

was used for the estimate with block sizes of 20mNS by 5mEW by 5m vertical with a minimum subblock

size of 5mNS by 1.25 m EW by 1.25m vertical.

The interpretation was based on a nominal 0.4g/t gold lower grade cut‐off and a minimum downhole

intersection of 2m to allow for potential open pit mining. The main mineralised trend is interpreted to be

350m long, extends 100m below the base of the existing mined pit and varies in width from 30m to 3m

wide along strike. The mineralised domain dips variably to the west between 60‐85 degrees. There are also

2 supergene horizons interpreted at the northern and southern extents of the deposit that were delineated

in recent drilling. These are parallel to the surface and range in thickness from 2‐5m.

Base of laterite, base of complete oxidation (BOCO) and top of fresh rock (TOFR) surfaces were generated

based on the oxidisation and lithology logging in the database to create the weathering profiles of oxide,

transitional and fresh.

The dataset was assessed for bias from extreme grades that would require adjustment or top‐cut. The

results of the MRE and comparison with historical mining reconciliations suggest that top‐cuts are required


to be used for estimation purposes. A top‐cut of 25 g/t was selected based on analysis of the dataset and

the grade distribution.

The search criteria were based on the overall orientation of the individual domain geometries and the

variogram models. Ellipses were orientated along the main axis of the lode.

Bulk density (BD) samples were collected from downhole density logging completed in 2013 and

reconciliation data from mining in 2000. Samples from nearby deposits were also used to assign BD’s.

Assigned BD’s were:

oxide/highly weathered: 1.7

transition/weathered: 2.1

fresh: 2.7

The Mineral Resource is classified as Indicated and Inferred based on the density of drill data, the geological

understanding of the deposit, consistency of gold assay grades and the likelihood of mining taking place.

Further refinement of the classification could be completed based on optimisation studies.

Metallurgy

Metallurgical studies are in progress.

Appendix 2

JORC Code, 2012 Edition – Table 1 Report – Phase3 RC Drilling at the Panther deposit

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

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.

The sampling of reverse circulation (RC) drilling included a total of 20 holes for 1308 metres on 1m sampling intervals, which were completed around the existing pit perimeter, to test extensions of known mineralisation trends.

Include reference to measures taken to ensure sample representation and the appropriate calibration of any measurement tools or systems used.

The drill hole collar locations were surveyed by RTK using Kalgoorlie based registered surveyors of Minecomp Pty Ltd. Sampling was carried out under Beacon’s protocols and QAQC procedures as per industry best practice. See further details below.

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.

The RC holes were drilled using a 133 mm face‐sampling bit. One metre samples were collected through a cyclone. A sample size of approximately 3‐4kg was collected for each metre. All samples were pulverised at the lab to ‐75um, to produce a 50g charge for Fire Assay with an AAS finish. Blanks, Std’s and duplicate samples were collected and submitted with each submission.

Drilling techniques

Drill type (eg core, reverse circulation, open‐hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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).

The RC drilling rig, owned and operated by Jarahfire Drilling, was used to collect the samples for this second phase of RC drilling. The RC drill bit has a diameter of 133 mm.



Drill sample recovery

Method of recording and assessing core and chip sample recoveries and results assessed.

The majority of samples were dry. Ground water ingress occurred in some holes at rod change, but overall the holes were kept dry. Typically, drilling operators ensured water was lifted from the face of the hole at each rod change to ensure water did not interfere with drilling and to make sure samples were collected dry. RC recoveries were visually estimated, and recoveries recorded in the log as a percentage. Recovery of the samples was good, generally estimated to be full, except for some sample loss at the collar of the hole.

Measures taken to maximise sample recovery and ensure representative nature of the samples.

RC face‐sample bits and dust suppression were used to minimise sample loss. High pressure air via compressor was used ensure to dry sampling. RC samples are collected through a cyclone and then split to capture a 3 to 4 Kg sample.

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.

No relationship between recovery and grade has been identified.

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.

All chips were geologically logged by a Beacon Senior Geologist using the Beacon Minerals geological logging legend and protocol.

Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.

Logging of RC chips and drill core records lithology, mineralogy, mineralisation, weathering, colour and other features of the samples. All samples are wet‐sieved and stored in a chip tray.

The total length and percentage of the relevant intersections logged

All holes were logged in full.

Sub‐sampling techniques and sample preparation

If core, whether cut or sawn and whether quarter, half or all core taken.

Not applicable. The drill holes are reverse circulation in nature.

If non‐core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.

One‐metre drill samples were collected below a rig mounted cyclone and riffle splitter, and an average 3‐4 kg sample was collected in a pre‐numbered calico bag and positioned on top of the reject. >98% of samples were dry.

For all sample types, the nature, quality and appropriateness of the sample preparation technique.

Samples for the RC programme of Panther were prepared at the ALS Laboratory in Kalgoorlie. Samples were dried, and the hole sample pulverised to 90% passing ‐75um, and a sub‐sample of approx. 200g retained. A nominal 50g was used for the fire assay analysis. The procedure is industry standard for this type of sample.



Quality control procedures adopted for all sub‐sampling stages to maximise representation of samples.

A CRM standard, fine blank and field duplicate was submitted at a rate of approximately 1 in 30 samples. At the laboratory, regular Repeats and Lab Check samples are assayed.

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.

The technique to collect the one metre samples was via a rig mounted riffle splitter. The riffle splitter was routinely inspected by the field geologist. Field duplicates were collected, and results were satisfactory, suggesting the duplicate field samples replicated the original samples.

Whether sample sizes are appropriate to the grain size of the material being sampled.

Sample sizes are considered appropriate to give an indication of mineralisation given the particle size and the preference to keep the sample weight at a targeted 3 to 4kg mass.

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.

Samples were analysed at the ALS Laboratory in Kalgoorlie. The analytical method used was a 50g Fire Assay with AAS finish for gold. The technique is considered to be appropriate for the material and style of mineralization.

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.

No geophysical tools were used in this program.

Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.

The Beacon QA/QC protocol used at Panther was for a single CRM (Certified Reference Material), fine blank and field duplicate to be inserted in every 90 samples. This at a rate of approximately 1 QA/QC sample per 30 regular samples. At the ALS Laboratory, regular assay Repeats, Lab Standards and Blanks are analysed. Results of the Field and Lab QAQC were analysed on assay receipt. On analysis, all assays passed QAQC protocols, showing no levels of contamination or sample bias. Analysis of field duplicate assay data suggests appropriate levels of sampling precision have been achieved for the sampling technique employed.

Verification of sampling and assaying

The verification of significant intersections by either independent or alternative company personnel.

Significant results were checked by Beacon Minerals mining team and BMGS Senior Geologists.

The use of twinned holes. No twinning of RC holes was completed in this small programme.

Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.

All field logging is carried out manually and transferred into an Access database. Assay files are received electronically from the Laboratory. All data is stored in the



Panther Gold Project Access database and managed by BMGS and Beacon Minerals.

Discuss any adjustment to assay data. No assay data was adjusted.

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.

RC hole collar locations were surveyed by a registered Surveyor. The group used was the Kalgoorlie based Minecomp Pty Ltd. Thirty six (36) of the holes were vertical, whilst the remainder were angled at between ‐50˚ to ‐72˚. All holes were surveyed using a down hole Reflex EZgyro.

Specification of the grid system used. Grid projection is MGA94, Zone 51.

Quality and adequacy of topographic control. Minecomp Pty Ltd has completed an aerial topographic survey over the lease picking up the existing open pit on the Mining Lease.

Data spacing and distribution

Data spacing for reporting of Exploration Results. The drilling was located to follow‐up on previously identified areas of gold mineralisation whilst taking into account practical drill set‐up locations.

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.

This spacing is sufficient to test the continuity of mineralisation of the Panther deposit.

Whether sample compositing has been applied. All RC samples collected were 1 metre composites.

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.

It is considered the orientation of the drilling and sampling suitably captures the “structure” of the style of mineralisation.

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.

This is not considered material.

Sample security

The measures taken to ensure sample security. Samples were transported by company transport to the ALS laboratory in Kalgoorlie.

Audits or reviews

The results of any audits or reviews of sampling techniques and data.

Sampling and assaying techniques are industry standard. No specific audits or reviews have been undertaken at this stage in the program.


Section 2 Reporting of Exploration Results (Criteria listed in the preceding section also apply to this section.)


Mineral tenement and land tenure status

Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.

The RC grade control has been within tenement M16/365, of which BCN holds a 100% controlling interest.

The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.

The tenement is in good standing with the WA DMIRS.

Exploration done by other parties

Acknowledgment and appraisal of exploration by other parties. 1990‐1997 Coolgardie Gold NL (CGNL) conducted extensive exploration programs in the Jaurdi area between 1990 and 1997, covering tenements from Carbine to south of Jaurdi Mining Center (e.g., Williamson and Copeland, 2000). And north to Jaurdi Hills, Dunnsville, Eight Mile Rock, Mayor’s Pool, and Gorge Dam and Panther. Auger drilling to 1.4 m depth at a 320 m by 80 m grid spacing was undertaken between the Panther anomaly and the Jaurdi Mining Center as well as southeast of the Black Cat prospect. Rotary air blast (RAB) drilling was undertaken to follow‐up anomalies identified in the soil geochemical program. Exploration at the Jaurdi Hills Project by CGNL resulted in the definition of gold resources at the Panther, Black Cat, and Jaurdi Mining Center anomalies, estimated at 586,000 tonnes grading 2.98 g/t Au in all resource categories (Australian Mining Consultants, 1996). 1998‐2000 Kinver Mining NL (Kinver) conducted exploration of the Property between 1998 and 2000 and this work included a digital compilation and re‐interpretation of historic data, grid construction and verification, ground geophysical surveying, prospecting, geologic mapping, RC drilling (5,256 m in 81 holes, as well as modelling of selected resources for resource estimation. 2000 Prospecting in 2000 was conducted by Kinver over areas of anomalous gold in soils using handheld metal detectors. Significant near‐surface gold at two locations was discovered and recovered, at the Panther North target area (about 800 m north‐



northeast of the Panther deposit) and at another area about 750 m east of Jaurdi Mining Centre. At the Panther North area about 200 ounces of gold were recovered from the upper couple of meters of soil using hand shovels and a backhoe; at the area east of Jaurdi Mining Center, nearly 50 oz of gold was recovered. Kinver also conducted some drilling at the Panther deposit to follow up anomalies identified in CGNL’s RAB and RC drilling programs; Kinver’s drilling yielding a best intersection of 7.93 g Au/t (0.26 oz Au/t) over 31 m. 2001 The Panther deposit was open‐pit mined in 2001. A total of 70,720 dmt @ 2.66g/t Au for 6,061 ounces was mined by Kinver. 2013 Sentosa Mining undertook a small RC programme which confirmed the moderate westerly dip and shallow northerly plunge of the Panther mineralisation.

Geology Deposit type, geological setting and style of mineralisation. The Panther Project lies within the northwest trending Dunnsville– Ubini greenstone belt of Archean age (Swager, 1989). The greenstone belt is folded around the Dunnsville and Doyle Dam granodiorite plutons and forms a doubly plunging antiformal structure. One such thrust, the Jaurdi Shear Zone, transects the project area. The greenstone sequence has been intruded south of Panther by the syn‐D2 Dunnsville granodiorite. Upright D2 deformation also resulted in north‐westerly trending domal structures, and regional scale synforms and antiforms. These include a regional scale F2 antiformal axis that trends south‐easterly along the Dunnsville Granodiorite but swings south‐south‐westerly in the vicinity of the Jaurdi Mining Centre–Black Cat area (Swager, 1989). The Doyle Dam Granodiorite, and Silt Dam and Bali Monzogranites, were emplaced post D2 or during D3 deformation, and disrupted the trace of F2 folds. During D3, there also was development of major north‐north‐westerly trending strike slip shears that extend through the project area. Similar, major sub parallel D3 structures include the Kunanalling Shear Zone to the east and the Bullabulling shear zone and Mt. Ida fault which lie to the west of the Jaurdi shear zone. Subsequent D4 deformation resulted in further sinistral movement along the D3 shear zones and, during late D4 time, in northwest‐ and northeast‐trending dextral strike slip faults. The



regional metamorphic grade ranges from upper greenschist to lower amphibolite facies, with strong serpentinization of the ultramafic rocks.

Drill hole Information

A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: easting and northing of the drill hole collar elevation or RL (Reduced Level – elevation above sea

level in metres) of the drill hole collar dip and azimuth of the hole down hole length and interception depth hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.

A total of 20 RC resource definition holes were drilled around the perimeter of Panther pit. All holes and significant assays are reported in Appendix 1.

Data aggregation methods

In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut‐off grades are usually Material and should be stated.

Grades are reported as down‐hole length‐weighted averages of grades above approximately 0.5 ppm Au. No top cuts have been applied to the reporting of the assay results. Intercepts averaging values significantly less than 0.5 g/t Au were assigned the text “NSI” (No Significant Intercept).

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.

Higher grade intervals are included in the reported grade intervals.

The assumptions used for any reporting of metal equivalent values should be clearly stated.

No metal equivalent values are used.



Relationship between mineralisation widths and intercept lengths

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 down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’).

The geometry of the mineralisation has been well established by the recent drilling, which has provided crucial information regarding orientation of sheared structure hosting the significant intercepts.

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.

Refer to Figures 2 and 3 in the body of text and appendix 1 for significant intercepts.

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.

No misleading results have been presented in this announcement.

Other substantive exploration 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.

There is nothing to report relevant to this programme.

Further work The nature and scale of planned further work (eg 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 sesitive.

Further exploration work is currently under consideration, the details of which will be released in due‐course including a follow up drilling program – Panther Phase 4


Section 3 Estimation and Reporting of Mineral Resources


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.

Database inputs were logged electronically at the drill site. The collar metrics, assay, lithology and down‐hole survey interval tables were checked and validated by numerous staff of BMGS.

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.

BMGS staff based out of the BMGS Kalgoorlie office have visited the Panther site on numerous occasions.

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.

Logging, where available, of the lithology has correlated well with resultant assay values and is in‐line with intercepts from historical drilling programs. RC and DD drilling data has been used in the estimation. Geological logging was utilised for identification of the mineralised units where available and for guiding the interpretation of bulk density using weathering profiles. The drill holes at Panther are orthogonal to the Panther shear and are orientated to the east. Recent drilling completed in 2020 was limited by access to suitable collar locations. Some down plunge drilling occurred as a result. Extensive vertical drilling has delineated horizontal, supergene style mineralisation at northern and southern extents of the deposit.

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 total strike length of the Panther mineral resource extends 350m in a Northerly orientation. The mineralisation domain for interpretation has encompassed all mineralisation, which consists of flat



lying and vertical vein sets within a deformed shear zone. The mineralised zone is up to 30m thick and dips variably to the west between 60‐80 degrees.

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 variables of economic significance (eg sulphur for acid mine drainage characterisation). 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 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.

Grade estimation was completed via ordinary kriging (OK). A nested spherical variogram with two structures was derived for each OK domain using Snowden Supervisor software. The variogram was created as normal scores and was back transformed for use with 3D Surpac modelling software. Estimations were completed using varying top cuts and evaluated against raw data and previous historical mining to assess validity. Nil assumptions were made. Three domains were created, based on variable grade distribution and orientation of mineralisation. A statistical analysis was undertaken, domains with high degree of grade distribution and corresponding coefficient of variation had top‐cuts applied Nil by‐products have been identified. Nil deleterious elements have been identified. Block sizes were based predominantly on drill spacing sizings and the likely mining options. Parent blocks sizes of 20mY, 5X and 5m Z were selected with sub‐blocking to 5mY and 2.5m in the X and Z orientations. Nil assumptions were made regarding correlation between variables A statistical analysis was undertaken for determination of a Gold top‐cut for each domain. All domains displayed a positive skew typical of gold deposits. The central/main lode had a very high Coefficient of Variation (CV) which is indicative of dual populations of data.



The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available.

An earlier resource estimate, completed by previous owners in 2013 was used as a check, as well visual checks and a series of swath validation plots that spatially compare block grades to raw composite data. Reconciliations were completed against mining data from 2000 and the resource figures were within 12% of mined reconciled ounces for the previously mined areas, using the same lower cut off grades

Moisture Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content.

Tonnage has been estimated on a dry basis. Bulk density value was estimated based on taking into account values typical of Goldfields oxidized profiles. Density values were also aligned with previous mining reconciliations to ensure representivity.

Cut‐off parameters The basis of the adopted cut‐off grade(s) or quality parameters applied.

A suite of cut‐off grades was presented for a scoping study. 0.6 g/t Au was selected as the optimal cut‐off grade.

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 assumption of open‐pit mining, using a 90t backhoe excavator was used. Minimal mining dilution is expected due to the simplicity and orientation of mineralisation. A minimum of 2m down‐hole width was applied to the interpretation. Internal waste zones were included within the main mineralised zone to ensure overall geological continuity. This was also based on reviewing GC drilling data from historical mining showing grade variability on scale closer than the resource definition drilling.



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.

Detailed metallurgical analysis is underway and will be factored into the economics of the deposit when complete. Further work will be undertaken to identify any potential deleterious elements.

Environmen‐tal 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.

Waste material is expected to be back‐filled into completed sectors of the open‐pit. The location of ore treatment will be Beacon Minerals ore processing facility at Lost Dog; 7.5 Km south of the Panther Deposit. A detailed environmental study will be undertaken before any mining activity takes place.

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

A down‐hole geophysical survey was undertaken during August 2013. The survey was conducted on 4 RC drill holes. A density reading was taken at a 1cm interval down‐hole. The down‐hole density readings were then cleaned to remove outliers and unrealistic values.



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.

A comparison of the down‐hole data mining data collected from 2000 was undertaken before applying an SG of 1.7 g/cm3 (oxide), 2.1 g/cm3 (transitional) and 2.7 g/cm3 (fresh). It is anticipated that further diamond core will be drilled prior to mining for confirmation of bulk 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 (ie 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.

Resource classification as Indicated or Inferred was based on drill‐hole density and confidence in the continuity of mineralisation. The current classification is considered appropriate for the current level of geological knowledge and continuity within the broad dimensions of the hosting mineralisation. The Mineral Resource classification and results appropriately reflect the Competent Person’s view of the deposits and the current level of risk associated with the project to date

Audits or reviews The results of any audits or reviews of Mineral Resource estimates.

Nil audits have been undertaken of the Panther deposit.

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

Comparison of mined tonnes and grade from historical mining in 2000 and the current model indicated a ounces variation of 12% between quoted resources above a 2 g/t lower cut‐off grade, which was used in 2000.



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.
