EXCELLENT LITHIUM DRILL RESULTS CONTINUE TO ESTABLISH

PROSPECTIVITY OF DORCHAP LITHIUM PROJECT

Dart Mining NL (ASX:DTM) (“Dart Mining” or “the Company”) is pleased to announce further results from the Phase 1 diamond drilling program from the Dorchap Range Lithium project under the Sociedad Química y Minera de Chile S.A (NYSE: SQM ) $12 million SQM earn in agreement with Dart Mining. Assays from drill holes MIDDH009 & MIDDH010 have continued to highlight the prospectivity of the Dorchap Dyke Swarm for ongoing lithium exploration.

DORCHAP RANGE Li-Cs-Ta PEGMATITES

• Drill holes MIDDH009 and MIDDH010 targeted the Boone’s Dyke within the Dorchap Dyke Swam, one of 5 mapped pegmatite dykes drill tested during Phase 1 of drilling.

• Highlight assay results included:

• MIDDH009

  • 10.0m @ 1.08% Li2O from 313m

    • Including 7.0m @ 1.38% Li2O from 315m

• MIDDH010

  • 2.0m @ 1.07% Li2O from 302m

    • Including 1.0m @ 1.38% Li2O from 303m

• Results to date have been received from 5 out of 12 holes drilled across 5 dykes. All drill holes returned to date have shown elevated levels of lithium mineralisation.

• Assay results returned continue to support the prospectivity of the Dorchap Range Li-CsTa Pegmatite Dyke swarm to host significant levels of Lithium mineralisation.

• Dart Mining has granted SQM, the right, to sole fund exploration expenditure totalling A$12million .

• During the first earn in period, SQM may earn an initial 30% interest in the Dorchap Lithium Project by sole funding exploration expenditure of A$3million

Chairman, James Chirnside commented: “The outstanding results from Holes 9 and 10 confirm the growing potential of the Dorchap Dyke swarm as an exciting new region for lithium exploration. The width and grades intersected are very solid and adds further to Dart’s cumulative knowledge of the Dorchap Lithium project.”

Discussion of Drilling Results

The results from drill holes MIDDH009 and MIDDH010 continue to develop the understanding of the Dorchap Range Lithium exploration project and build on the previously reported results from holes MIDDH001, MIDDH002 and MIDDH005 into the Eagle and Fergusson pegmatite dyke targets ( Dart Mining ASX June 2023 ). The drilling clearly highlights the prospectivity of the Dorchap Dyke Swarm to host significant grades of Lithium Mineralisation.

The narrow interval of the peak assay result from MIDDH002 (0.81m @ 1.2% Li2O) and the broad exomorphic halos reported from the Eagle Dyke drilling ( Dart Mining ASX June 2023 ) were interpreted to have resulted from the complex structural history of dyke emplacement. Dart Mining geologists currently interpret that syn-emplacement to post-emplacement shearing (extensive at the Eagle Dyke) has generated mylonitic (sheared) textures that likely caused partial recrystallisation of the pegmatite and re-mobilised the contained lithium from the dyke into surrounding sediments. This process may be responsible for the broader, but overall lower grade lithium intersections at Eagle dyke. In contrast, structural and lithological logging of drill holes MIDDH009 and MIDDH010 from the Boones dyke target (Figure 1,2 and 3) show only narrow zones of mylonitic textures within the dykes. This represents a significant increase in the proportion of large primary crystals of lithium minerals inbound from the dyke margins with a consequent marked increase in reported lithium grades. The structural evolution of the region appears critical to emplacement and development of the pegmatite dykes and is a critical, ongoing focus for Dart Mining moving forward.

MIDDH009 intersected 10m @ 1.08% Li2O (See Appendix 1) from 313m (including 7m @ 1.38% Li2O) from the western dyke structure at Boones (Figure 1 and 3). The Boones dyke appears to dip steeply (84[0] ) to the west and shows geological continuity extends below 200m depth from surface. The true width of the pegmatite based on surface mapping and the current drill interpretation is between 5 – 13m with an open strike extent of some 300m at surface. The drill intersection assay highlight is approximately 5m in true width with the drill hole orientation approximately perpendicular to the strike of the pegmatite.

MIDDH010 intersected 2m @ 1.07% Li2O (See Appendix 1) from 302m from the western dyke, some 90m along strike from the western dyke intersection in MIDDH009 (Figure 2 and 3). Geological continuity extends below 175m depth from surface with the true width of the pegmatite drill intersection being approximately 5m. The drill intersection orientation is approximately perpendicular to the strike of the dyke with the assay highlight having a true width of approximately 1.1m.

Sampling and logging of pegmatite intersections in the remaining 7 drill holes of the Phase 1 drill program is complete. Further assay results are expected over the coming 4-6 weeks and will be reported as results come to hand.

Dorchap Lithium Project Summary

Dart Mining geologists first identified the lithium prospectivity of pegmatite dykes in the Dorchap Range in 2016 and set about acquiring exploration leases across the region ( Dart Mining ASX May 2016 ; Dart Mining ASX August 2016 ). These are the first recorded lithium pegmatites identified in Victoria, and are believed to have been sourced from the nearby Mount Wills Granite. A regional sampling program consisting of 826 samples has identified a strong fractionation trend across the Dorchap Range, resolving a 20×12 km zone of strongly fractionated pegmatites bearing enriched Li, Cs, Ta, Be and Sn mineralisation ( Dart Mining ASX July 2021 ).

Dart Mining’s chip sampling program has seen some rewarding results, including: 16m at >530 ppm Cs2O, 0.32% Li2O and 104 ppm Ta2O5, and grab samples at 1.57% Li2O and 0.1% Ta2O5 at the Bluejacket Dyke in Glen Wills, along with 10m at 0.95% Li2O from the Eagle Dyke and 10m at 1.38% Li2O from the Holloway Dyke (Dorchap Range), and 10m at 1.22% Li2O from Scrubby Dyke, 1m at 838 ppm Cs2O and 0.46% SnO2 , and a grab sample at 9.98% SnO2 from elsewhere in the Dorchap Range ( Dart Mining ASX July 2021 ). The initial, short drilling program in 2019 has been followed by an airborne LiDAR mapping program in early 2021 ( Dart Mining ASX March 2021 ), which has allowed additional, detailed mapping of pegmatite dykes that were previously overlooked in pockets of dense bush across the Dorchap Range.

APPENDIX 3

JORC CODE, 2012 EDITION – TABLE 1

SECTION 1 SAMPLING TECHNIQUES AND DATA

Criteria	JORC Code Explanation	Commentary
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.	• HQ diamond drill core was drilled using triple tube method to retain maximum sample recovery. • Diamond core was sampled as half core at 1m intervals or to geological or mineralogical boundaries, where relevant, to a minimum sample size of 0.2m and a maximum of 1.5m. To ensure representative sampling, half core samples were always taken from the same side of the core. • Only pegmatite dykes and contact zones are sampled due to the target mineralisation. • In interpreted unmineralised, mineralised or altered zones, samples were not submitted for analysis. • Samples submitted to ALS were whole sample crushed to 70% <2mm, riffle/rotary split off 1 kg, pulverise to >85% passing 75 microns, then assayed by ALS methods ME-MS61 (0.25g sample aliquot by four-acid digest and ICP-MS and ICP-AES analysis), ME-ICP89 and ME-MS91. • Certified Reference Materials OREAS 750, OREAS 751, OREAS 752, OREAS 753, and OREAS 999 as well as CRM blank OREAS C27c were inserted every 10 samples as part of a QA/QC system. • All-drill related data are referenced to the original ASX report by date published. All details appear in the original report. • Chip samples are taken continuously perpendicular to the general strike of mineralised structures in outcrop, and large samples (4 – 7kg) are taken where possible to provide a more representative sample. The chip samples are of adequate quality to be indicative of the area sampled. • Grab samples were collected from the outcrop over a small area (<1 – 5m in diameter). The grab samples are generally small (ie. <7kg) and represent the local area only, sampling only tests a small aerial extent, and are not considered as being representative of the outcrop. The grab samples are of adequate quality to be representative of the small area sampled and approximate the sampled in situ mineralisation. • Rock samples are dried, crushed and whole sample pulverized and riffle split. A sample aliquot (25g) is taken for analysis. Lithium has been analysed by ALS Method ME-MS61– a four acid digest assay technique for total digestion. • Individual <7kgchip / grab samples were collected from outcrop,individual chips

		making up the sample were <40mm and chipped from a random selection of the mineralisation to generate a representative average sample of the mineralisation targeted. • Semi-quantitative XRD results we analysed from the same sample pulp analysed for multi-element geochemistry. • X-ray diffraction traces were obtained from the samples with a Panalytical Aeris Research Powder Diffractometer. Operating conditions were 40kV/15mA, Fe Kß filter, step scan 0.01/29 secs˚2Ɵ at, 1/4˚ divergence and a 1.0˚ ant-scatter slit. Scan range was 5° to 90° 2Ɵ. Phases were identified by computer search/match of the COD and ICDD 2022 Databases. Quantitative results have been determined with full pattern Rietveld refinement software.
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.).	• 12 diamond holes drilled by DDH1 Ltd across the mineralised structures. • 3 RC drillholes were drilled by EDrill Pty Ltd limited over two mineralised dyke structures. • Diamond Drilling (Core) is of HQ3 (63.5mm diameter) from surface. Drill holes are angled, and core is orientated (Reflex Tool) to allow structural interpretation (not yet completed) • Face sampling 5.25” hammer Reverse Circulation drilling • Holes surveyed using an Trushot downhole camera, both open hole and within rods (for dip). Verified using clinometer and compass survey of rods. • Face sampling 5 ¾’ RC drilling • Each 2m composite sample was weighed and results recorded to monitor sample recovery – a high average recovery was achieved in all holes. • Experienced geologists ensured best drilling and sampling practices were maintained. • Experienced drillers ensured best drilling and sampling practices were maintained, including pausing drilling between sample intervals to ensure all sample is out of the system and regular cleaning of the sampling equipment. • There was no observable relationshipbetween sample recoveryandgrade.
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.	• Drill core recovery is recorded for each drill interval recorded by the drill contractor. The drilled interval (recorded on core blocks) and the recovered interval (measured during logging) are recorded in the company drill log database and recovery is calculated as a percentage. • Drilling techniques are designed to maximise core recovery • No analysis of sampling has been carried out to date to establish if any relationship between sample recovery, grade and any possible sample bias may exist. • Drill chips were geologically logged at 1m intervals for lithology (including quartz types and percentages), alteration and mineralisation, and drilling conditions. • Representative chips from each metre were collected in chip trays. Chip trays were photographed. • 100% of the drillingwas logged.

13 | P a g e

==> picture [113 x 47] intentionally omitted <==

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.	• Drill core initial summary lithology logging is carried out to allow subsequent hole planning and to track hole geology against hole plan. Detailed geological logging of all drill core will follow and include recording of recovery, weathering, lithology, alteration, mineralisation and RQD. All drill core will be photographed prior to sampling. This logging is qualitative. • Drill chips were geologically logged at 1m intervals for lithology (including quartz types and percentages), alteration and mineralisation, and drilling conditions. • Representative chips from each metre were collected in chip trays. Chip trays were photographed. • 100% of the drillingwas logged.
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.	• All Diamond core was cut longitudinally using a brick saw with sampling of one half of the core, with the remaining core kept as reference. • No assessment of the appropriateness of the diamond core sampling method has been undertaken yet. • RC samples were collected from a riffle splitter mounted directly beneath the cyclone. • Samples from all intervals were collected as 1m composite samples at the splitting stage at the drill site. • 12.5% of the sample was split with the remainder collected in residue bags. • The majority of samples were dry, there were four wet samples collected across the whole drill program. • The sampling procedure is appropriate for the mineralisation style of large pegmatite dykes and is better described inDart Mining ASX 19thJune 2019. • The samples were sent to ALS Laboratories, Pooraka, SA. • XRD results were obtained from McKnight Mineralogy, Ballarat, Victoria. • Semi-quantitative XRD results we analysed from the same sample pulp analysed for multi-elementgeochemistry.
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.	• Samples were submitted to ALS Chemex and analysed for a suite of trace elements using ALS Methods ME-ICP89 and ME-MS91 (a peroxide leach is considered a total extraction technique for lithium). These techniques are appropriate and considered a total extraction technique for key metals Rb, Nb, Sn, Nb, Ta, Cs and Li. • Samples were whole sample crushed, pulverised to P85 at 75um and assayed by ALS methods ME-ICP89 and ME-MS91. • Lithium pegmatite standards OREAS 147, OREAS 148, and OREAS 149, as well as rhyodacite blanks (OREAS C27e) were included every 10 samples as part of the internal QA/QC system. All results are within expected confidence limits. • ALS conducted their own internal laboratory checks. • Laboratory blanks, standards are reviewed per batch to monitor accuracy and precision. • For rock chip samples, due to the reconnaissance nature of the sampling, no QAQC procedures were adopted other than internal laboratoryCRM.

		• XRD data is semi-quantitative which is considered appropriate at this stage of exploration.
Verification of sampling and assaying	• 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.	• Sample duplicates (quarter sawn) are submitted every 20thsample. • Geological logging is completed by experienced geologists • The laboratory supplies all assay data as an export to a CSV file. The raw data is edited to separate all duplicates and CRM results into a QA/QC tab in the CSV file and reviewed. • Verification of significant intersections were made by alternative company personnel. • No independent review of assay data has been carried out. • Geological data were logged onto paper and transferred to a spreadsheet and checked. • Electronic-only assay data is imported into a spreadsheet from the laboratory’s electronic data. • No holes were twinned at this early exploration stage. • Lithium analysis reports Li%, Li2O (%) is derived by using a conversion factor: Li2O = Li x 2.153 • Tantalum analysis (where reported) Ta (ppm) Ta2O5(ppm) is derived by using a conversion factor: Ta2O5= Ta x 1.2211
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.	• The location of drill hole collars and geological mapping confirmed using a Garmin GPSMAP 62s GPS, set to MGA94 Grid Datum (Zone 55) with topographic control taken from the GPS. Accuracy is variable but maintained <5m during the mapping process with constant visual quality assessment conducted. • Hand-held GPS was used to survey a control point and drill hole collar positions are then measured by tape and compass relative to the GPS control. The accuracy between holes is <0.5m but absolute accuracy is relative to the original GPS control point at <5m. • Down hole, multi-shot surveys were taken at a nominal 30 m interval where possible in an open hole (percussion) or in rod (diamond drilling). Where the percussion hole was suspected to have collapsed a downhole, multi-shot survey was conducted within the rods to determine dip. • All maps, plans and data are on an MGA datum and GDA94 zone 55 projection. • Elevation is established from the GPS control point. • Mine workings were located using GPS control and then tape and compass surveyed for underground development.
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 estimationprocedure(s) and classifications	• Drill sites were restricted to existing tracks. It was not intended to establish a drill spacing for resource estimation although these holes can be used at a later date. • Drill core sampling minimum 0.2m and maximum 1.5m with sampling to lithological and mineralogical boundaries and is considered appropriate for the style of

This sample interval is considered appropriate for the style of pegmatite mineralisation tested. • All drill related data are referenced to the original ASX report by date published. All details appear in the original report. • Where exposure allows, multiple chip samples are collected across mineralised structures to assess the continuity of Li grade. • Rock chip sampling is limited by outcrop exposure. • Reconnaissance-scale chip / grab samples are not presented or considered to be representative of the average grade. Grab samples only represent the grade at a single point within the rock exposure. Sample spacing is designed to allow an initial assessment of lithium mineralisation and is not suitable for future resource estimation activities.
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.	• Drilling was restricted to existing tracks and pads. However, in all cases it was possible to drill at a high angle to the host structures (refer toDart Mining ASX 19th June 2019)and achieve a suitable orientation that cross cuts the mineralised dykes. True width intersections are provided in drill sections (Dart Mining ASX 19thJune 2019), there appears to be no relationship between drill orientation and mineralisation grades. • Drill transects were oriented perpendicular across the known trend of major structures.
Sample security	• The measures taken to ensure sample security.	• All samples submitted for analysis are placed in sealed poly-weave bags and delivered to a commercial transport company for delivery to the laboratory. Any evidence of sample damage or tampering is immediately reported by the laboratory to the company and a decision made as to the integrity of the sample and the remainingsamples within the damaged/tampered bag/s.
Audits or reviews	• The results of any audits or reviews of sampling techniques and data.	• An internal review of procedures, operations, sampling techniques and analytical techniques was made by Dart Mining. • The mapping and sampling methodology and results were documented and reviewed bythe competentperson for this report.

SECTION 2 REPORTING OF EXPLORATION RESULTS

Criteria	JORC Code Explanation	Commentary
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 security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.	• All tenements remain in good standing as of 31stAugust 2023 • Details of Dart Mining tenements shown in Appendix 2 and Figure 4
Exploration done by other parties	• Acknowledgment and appraisal of exploration by other parties.	• No commercial exploration for Li has previously occurred, geological investigations as part of academic research has been reported for the pegmatite dykes of the area in: - Eagle, R. M., 2009. Petrology, petrogenesis and mineralisation of granitic pegmatites of the Mount Wills District, northeastern Victoria. Unpublished thesis, University of Ballarat. - Eagle, R. M., Birch, W. D & McKnight, S., 2015. Phosphate minerals in granitic pegmatites from the Mount Wills district, northeastern Victoria. Royal Society of Victoria. 127:55-68. • Previous exploration in the district has focused on gold exploration at Glen Wills and historic Snproduction frompegmatite dykes.
Geology	• Deposit type, geological setting and style of mineralisation.	• Lithium mineralisation is hosted within highly evolved, late tectonic peraluminous granite pegmatites of the complex Lithium, Caesium, Tantalum (LCT) class. These dykes are thought to be distal to a source granitic body and are present as lenticular, discontinuous bodies of variable length and width (up to many hundreds of metres in length and tens of metres in width). Lithium mineralisation within the pegmatites is poorly understood at this early exploration stage but suspected to be spatially related to the zonation within the complex pegmatites. Lithium mineralisation observed to date appears to be as spodumene and Petalite with Cassiterite also evident within some of the dykes.
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: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detractfrom the	• All drillhole data (location, RL, azimuth, dip, depth etc.) for this drilling program is presented in the body of this report, referenced drill locations also appear inDart Mining ASX 19thJune 2019. • Additional sampling and drillhole collar information is presented in previous Dart Mining ASX Announcements and Releases. An archive of historic Dart Mining ASX releases is held at: https://www2.asx.com.au/markets/trade-our-cash- market/announcements.dtm

	understanding of the report, the Competent Person should clearly explain why this is the case.
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.	• The length weighted average lithium content of the pegmatite dykes are provided across the full intersection width in each drill hole. The nominal sample length is 1m with a limited frequency of <1m sample lengths requiring a length weighted average technique to be used for reporting dyke intersections. No grade cutting or cut-off grade has been applied in reporting the average lithium grades across dyke drill intersections at this early stage of exploration. • All drill-related data are referenced to the original ASX report by date published. All details appear in the original report.
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 (e.g. ‘down hole length, true width not known’).	• The relationship between the drill hole and the geometry of the mineralised pegmatite dykes is clearly presented in a series of summary cross sections and drill plans. The angle between the drill hole and the dyke structure is variable with an interpretation of the relative geometry presented as cross sections down hole, down hole average grades are also presented on these drill sections and are representative of the current geological interpretation, this interpretation may change over time as more drilling information become available. Dyke interpretation is constrained with surface geological mapping and down hole lithology logging. • All drill-related data are referenced to the original ASX report by date published. All details appear in the original report.
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 summary table showing the hole location and orientation for all drilling is presented in Table 2, referenced past drilling locations appear inDart Mining ASX 19thJune 2019.Drill plans and cross sections are also presented for all holes to illustrate the relationship between drill holes and average grades from down hole intersections within the target structures (Dart Mining ASX 19thJune 2019). Sampling data for primary discussed mineralised dykes at Boones is shown in figure 1 & 2.
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.	• Where mentioned, selected grade details and intercepts are included in the body of the report of this release, or else referenced back to the relevant release or data source. • All drill-related data are referenced to the original ASX report by date published. All details appear in the original report.
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.	• Any other relevant information is discussed in the main body of the report.
