Havieron Exploration and Development Update

South East Crescent high grade zone extended which following recent Growth Drilling

is now identified at extending over 1,000 metres of continuous mineralisation, and remains open

High grade results within the Northern Breccia continue to demonstrate the potential for

further high-grade mineralisation adjacent to the South East Crescent Zone

Extensive Growth Drilling programme planned across the next twelve months,

which provides substantial opportunity to expand Havieron

Greatland Gold plc (AIM:GGP), a mining development and exploration company with a focus on precious and base metals, is pleased to provide an exploration and development update at the Havieron gold-copper project in the Paterson region of Western Australia.

Highlights

-- Seven drill rigs currently onsite, all focused on growth targeting:

-- South East Crescent: continuous mineraliation identified across 1,000 vertical meters and remains open. Drilling continuing to progressively test for extensions to the South East Crescent, with drilling planned up to 400 metres below the Updated Mineral Resource(1)

-- Eastern Breccia: drilling continuing to define the greater mineralised footprint of the Eastern Breccia, including definition of higher-grade zones recently announced

-- Northern Breccia: drilling aimed at extending high-grade zones of mineralisation at depth

-- New Targets: drilling continuing to define geophysical targets outside of the main Havieron system with follow-up drilling planned at regional targets on the Havieron mining lease

New drilling results

-- Drilling in the South East Crescent has extended the high grade zone down a further 100 metres with Crescent zone having now been continuously intersected to over 1,000 vertical metres (3800m RL(2) ) and remaining open at depth :

-- HAD133W9 returned 85.8m @ 3.0g/t Au & 0.06% Cu from 1,604m and 25.3m @ 1.1g/t Au & 0.08% Cu from 1,471.1m

-- High grade results in the Northern Breccia reinforce the potential for further high-grade sulphide mineralisation adjacent to the South East Crescent Zone:

-- HAD055W4 returned 149.9m @ 2.7 g/t Au & 0.12% Cu from 877.4m,

-- Including 13.9m @ 22.8 g/t Au & 0.46% Cu from 1,013.4m

-- HAD055W5 returned 39.6m @ 2.8 g/t Au & 0.07% Cu from 983.6m,

-- Including 0.5m @ 96.0 g/t Au & 0.10% Cu from 1,020.7m

-- Early Works improvements: Construction activities by Newcrest are progressing including:

-- An exploration decline advance of 377.5 metres as at end of May 2022

-- Fuel facility fully commissioned

The decline experienced improved ground conditions in the June quarter. Advance rates have improved after c hanges in the design of the decline brought forward the first downward spiral to the current advance position. This has allowed the decline to transition into better ground conditions. The Havieron fuel facility has now been completed and commissioned into operation.

-- Feasibility Study work by Newcrest is progressing and k ey contracts have been awarded. The Feasibility Study is still forecast to be delivered in the December 2022 quarter(3) .

Shaun Day, M anaging Director of Greatland Gold plc, commented: " The growth drilling programme continues to expand Havieron's mineralised system. The existing high grade mineralised zone of the South East Crescent now extends a further 100 metres below our previous Mineral Resource estimate. Testament to the scale of Havieron, there is now continuous mineralisation observed over 1,000 metres of vertical extent with the system remaining open at depth.

With an extensive growth drilling programme planned over the next twelve months, there is tremendous potential to further expand the Havieron resource and unlock the true scale and value of the broader system.

Pleasingly, the decline has encountered better ground conditions, resulting in recent improvements to the decline advancement rates."

Further Information on Drilling and Operations at Havieron

The Havieron gold-copper deposit is centered on a deep magnetic anomaly located 45km east of Telfer in the Paterson Province where exploration drilling by Greatland during 2018 resulted in the discovery of gold and copper ore under 420 metres of post mineralisation cover. The Joint Venture commenced drilling during the June 2019 quarter and has completed 243,618 metres of drilling from 295 drill holes to date (excluding holes in progress, abandoned holes or drill holes not yet sampled).

Drilling activities have produced a further 6,174 metres of drilling from 10 new holes since the last update ("Havieron Exploration and Development Update", RNS dated 28 April 2022). New assay results are reported from 7 holes. 4 holes returned significant assay intercepts in excess of 50 gram metres Au (Au ppm x length metres).

Growth drilling is focused on potential extensions at the South East Crescent Zone, Northern Breccia and Eastern Breccia, while regional exploration holes are planned to locate new discoveries outside the main Havieron mineralised system. Assays reported include drilling from:

-- South East Crescent Deeps - assay results reported for one drill hole.

-- Northern Breccia - assay results are reported for three drill holes.

-- Eastern Breccia - assay results reported for one drill hole, with five holes awaiting assays.

-- First pass drill testing of geophysical regional targets outboard of the Havieron system - two drill holes results from step out drilling north and south of the Havieron system.

There are now seven rigs on site, and the number of drill holes completed is expected to increase in future updates. The JV is targeting an extensive growth drilling programme in the 12 months to 30 June 2023 which has the potential to again expand the Havieron resource. Refer to Appendix 2 for all reported results.

At the South East Crescent Deeps Target, growth drilling continued, defining high grade mineralisation below the Updated Mineral Resource, which remains open at depth. Results were received from one drill hole - HAD133W9.

Results from HAD133W9 have extended the Crescent high grade zone by a further 100 metres to over 1,000 vertical metres (3800m RL) of continuous high grade crescent style mineralisation now defined. Further drilling is planned to test the potential for high-grade resource extensions for a further vertical extension of 300m (3500m RL).

Results include:

-- HAD133W9

-- 85.8m @ 3.0g/t Au & 0.06% Cu from 1,604m,

-- 25.3m @ 1.1g/t Au & 0.08% Cu from 1,471.1m

Northern Breccia infill drilling has confirmed known high-grade mineralisation within the core of the Northern Breccia, adjacent to the high grade South East Crescent.

Results include:

-- HAD055W4

-- 149.9m @ 2.7 g/t Au & 0.12% Cu from 877.4m,

-- incl. 13.9m @ 22.8 g/t Au & 0.46% Cu from 1,013.4m

-- HAD055W5

-- 76.5m @ 1.1 g/t Au & 0.11% Cu from 892.5m,

-- incl. 11.4m @ 1.9 g/t Au & 0.12% Cu from 921m

-- 39.6m @ 2.8 g/t Au & 0.07% Cu from 983.6m,

-- incl. 0.5m @ 96.0 g/t Au & 0.10% Cu from 1,020.7m

-- HAD055W6

-- 43.2m @ 1.4 g/t Au & 0.08% Cu from 978.3m,

-- incl. 10.9m @ 2.3 g/t Au & 0.05% Cu from 978.3m

At the Eastern Breccia, assays for one additional hole were reported (HAD104W1) with no significant mineralisation intercepted (Figure 2). This hole was drilled towards the east, at the junction between the currently defined Eastern Breccia mineralisation and the base of the South East Crescent Zone. In addition, 6 new holes were successfully drilled into the Eastern Breccia complex with assays pending.

Drilling to test geophysical targets outside of the known Havieron system, including evaluating the Havieron dolerite at multiple intervals north and south of the Havieron mineralised pipe revealed no significant intercepts from two drill holes (HAD154 & HAD155). Further drilling is planned external to Havieron in the coming months.

The JV is targeting an extensive growth drilling programme in the 12 months to 30 June 2023 which has the potential to further expand the Havieron resource. Growth drilling continues to show potential for resource additions outside of the existing Inferred Mineral Resource limits, including:

-- Extension of the South East Crescent Zone at depth below the Updated Mineral Resource;

-- Potential for additional material in the Eastern Breccia, including higher grade "Crescent" like material, currently open along strike and at depth;

-- Expansion of multiple higher-grade zones including Northern Breccia and North West Pod; and,

-- Additionally, drilling is continuing to target geophysical targets outside of the main Havieron system.

Refer to Appendix 1 for additional information and Appendix 2 for all drillhole results reported during the period.

Development Update

Newcrest has advised development of the exploration decline experienced improved ground conditions in the June quarter. Advance rates have recently improved after c hanges in the design of the decline have brought forward the first downward spiral to the current advance position. This has allowed the decline to transition into better ground conditions sooner. The Havieron fuel facility has now been completed and commissioned into operation.

Background to Havieron and Joint Venture Agreement with Newcrest

The Havieron copper-gold project is operated by Newcrest under a Joint Venture Agreement with Greatland. Newcrest has earned a joint venture interest of 70% (30% Greatland). Newcrest may also acquire an additional 5% joint venture interest at fair market value (under the principles of the Joint Venture Agreement) and, if exercised, Newcrest will be entitled to an overall joint venture interest of 75% (Greatland 25%). Greatland and Newcrest continued to progress the process to determine the option price for the 5% interest in accordance with the Joint Venture Agreement during the period.

The Joint Venture Agreement includes tolling principles reflecting the intention of the parties that, subject to a successful exploration programme and feasibility study and a positive decision to mine, the resulting joint venture mineralised material will be processed at Telfer, located 45km west of Havieron.

Section 1 Sampling Techniques and Data

 
 Criteria              Commentary 
 Sampling techniques   Samples are obtained from diamond core drilling in Proterozoic 
                        basement lithologies. 
                        Core is cut along the orientation line and one half 
                        consistently sampled. 
                        PQ-HQ and NQ diameter core was drilled on a 6m run. 
                        Core was cut using an automated core-cutter and half 
                        core sampled at 1m intervals or at breaks for major 
                        geological changes. Sampling intervals range from 0.2 
                        - 2.0m. Sample weights were typically between 0.7 and 
                        5.6 kg. Cover sequences were not sampled. 
--------------------  ------------------------------------------------------------------ 
 Drilling techniques   Permian Paterson Formation cover sequence was drilled 
                        using mud rotary drilling. Depths of cover typically 
                        observed to approximately 420m vertically below surface. 
                        Steel casing was emplaced to secure the pre-collar. 
                        Core drilling was advanced from the base of the cover 
                        sequence with PQ3, HQ3 and NQ2 diameter double tube 
                        coring configuration with minor HQ and PQ triple tube 
                        configuration. Navi drilling was undertaken to start 
                        wedged holes from parent holes. 
                        Core from inclined drill holes are oriented on 3m and 
                        6m runs using an electronic core orientation tool (Reflex 
                        ACTIII or equivalent). At the end of each run, the bottom 
                        of hole position is marked by the driller, which is 
                        later transferred to the whole drill core run length 
                        with a bottom of hole reference line. 
--------------------  ------------------------------------------------------------------ 
 Drill sample          Core recovery is systematically recorded from the commencement 
  recovery              of coring to end of hole, by reconciling recovered core 
                        measurements against driller's depth blocks in each 
                        core tray, as recorded in the database. Driller's depth 
                        blocks provided the depth, interval of core recovered, 
                        and interval of core drilled. Core recoveries below 
                        the cover sequence were typically 100%, with isolated 
                        zones of lower recovery. Cover sequence drilling by 
                        the mud-rotary drilling technique does not yield recoverable 
                        samples. 
                        Those sections of wedge holes that were Navi drilled 
                        did not produce recoverable sample material and have 
                        not been sampled. 
                        No specific measures have been taken to maximise recovery, 
                        other than employing professional and well respected 
                        drillers; 
                        There is no discernible relationship between sample 
                        recovery and the grade of any important variable. 
--------------------  ------------------------------------------------------------------ 
 Logging               Geological logging recorded qualitative descriptions 
                        of lithology, alteration, mineralisation, veining, and 
                        structure , including orientation of key geological 
                        features. 
                        Geotechnical measurements including Rock Quality Designation 
                        (RQD) fracture frequency, solid core recovery and qualitative 
                        rock strength measurements were recorded by Geologists 
                        or Geotechnical Engineers. 
                        All geological and geotechnical logging was conducted 
                        at the Havieron site. 
                        Magnetic susceptibility measurements were recorded every 
                        metre. The bulk density of selected drill core intervals 
                        was determined at site on whole core samples. 
                        Digital data logging was captured on diamond drill core 
                        intervals only, and all data validated and stored in 
                        a Datashed database. 
                        All drill cores were photographed (wet and dry), prior 
                        to cutting and/or sampling the core. 
                        The logging is of sufficient quality to support Mineral 
                        Resource estimates, mining studies and metallurgical 
                        studies 
                        100 percent of recovered core in the basement rocks 
                        has been logged. 
--------------------  ------------------------------------------------------------------ 
 Sub-sampling          Core was cut and sampled at the Havieron core processing 
  techniques            facilities. Half core samples were collected in pre-numbered 
  and sample            calico bags and grouped into bulk bags for dispatch 
  preparation           to the laboratory. Sample weights typically varied from 
                        0.7 to 5.6kg. Sample sizes are considered appropriate 
                        for the style of mineralisation. Sample lengths typically 
                        ranged from 0.2 to 2m with most samples being 1m in 
                        length. Drill core samples were freighted by air and 
                        road to the laboratory. 
                        Navi drilled sections of holes did not produce recoverable 
                        material and could not be sampled. 
                        Sample preparation was conducted at the independent 
                        ISO17025 accredited Intertek Laboratory, Perth (Intertek). 
                        Samples were dried at 105(o) C, and crushed to 95% passing 
                        4.75mm, and then split to obtain up to 3kg sub-sample, 
                        which was pulverised (using LM5) to produce a pulped 
                        product with the minimum standard of 95% passing 106<MU>m. 
                        Routine grind size analysis is conducted. Duplicate 
                        samples were collected from crush and pulp samples at 
                        a rate of 1:20. 
                        Coarse Crush and Pulp Duplicate results show an acceptable 
                        level of variability for the material sampled and style 
                        of mineralisation. 
                        Periodic size checks (1:20) for crush and pulp samples 
                        and sample weights are provided by the laboratory and 
                        recorded in the Datashed database. Field Duplicate samples 
                        are not (routinely) taken. 
                        Sampling and sample preparation sizes and quality control 
                        protocols are considered appropriate to the grain size 
                        of the material being sampled. 
                      ------------------------------------------------------------------ 
 Quality of            Assaying of drill core samples was conducted at Intertek. 
  assay data            All samples were assayed for 48 elements using a 4-acid 
  and laboratory        digestion followed by ICP-AES/ICP-MS determination (method 
  tests                 4A/MS907), which is considered to provide a total assay 
                        for copper. Gold analyses were determined by 50g fire 
                        assay with AAS finish (method FA50N/AA), which is considered 
                        to provide a total assay for gold. 
                        Sampling and assaying quality control procedures consisted 
                        of inclusion of certified reference material (CRMs), 
                        coarse residue and pulp duplicates with each batch (at 
                        least 1:20). Assays of quality control samples were 
                        compared with reference samples in the Datashed database 
                        and verified as acceptable prior to use of data from 
                        analysed batches. Batches failing QA/QC tests were re-submitted 
                        for assay. 
                        Laboratory quality control data, including laboratory 
                        standards, blanks, duplicates, repeats and grind size 
                        results are captured in the Datashed database and assessed 
                        for accuracy and precision for recent data. 
                        Extended quality control programs including pulp samples 
                        submitted to an umpire laboratory. 
                        Analysis of the available quality control sample assay 
                        results indicates that an acceptable level of accuracy 
                        and precision has been achieved and the database contains 
                        no analytical data that has been numerically manipulated. 
                        The assaying techniques and quality control protocols 
                        used are considered appropriate for the data to be used 
                        for reporting Exploration Results and Mineral Resources. 
                      ------------------------------------------------------------------ 
 Verification          Assessment of reported significant assay intervals was 
  of sampling           verified by re-logging of diamond drill core intervals 
  and assaying          and assessment of high-resolution core photography. 
                        The verification of significant intersections has been 
                        completed by Newcrest personnel and Newcrest's Competent 
                        Person/Qualified Person. 
                        No twinned holes have been drilled, however there are 
                        many 'wedge/daughter' holes that provide close-spaced 
                        intersections in adjacent holes. 
                        Sampling intervals defined by the geologist are electronically 
                        assigned sample identification numbers prior to core 
                        cutting. Corresponding sample numbers matching pre-labelled 
                        calico bags are assigned to each interval. Electronically 
                        generated sample submission forms providing the sample 
                        identification number accompany each submission to the 
                        laboratory. Assay results from the laboratory with corresponding 
                        sample identification are loaded directly into the Datashed 
                        database. 
                        No adjustments are made to any assay data. 
                        There are no currently known drilling, sampling, recovery, 
                        or other factors that could materially affect the accuracy 
                        or reliability of the data. 
                      ------------------------------------------------------------------ 
 Location of           Drill hole collar locations were surveyed using a differential 
  data points           GPS with GNSS with a stated accuracy of +/- 0.5m for 
                        all drill holes reported. 
                        Drill rig alignment was attained using an electronic 
                        azimuth aligner. 
                        Downhole survey data was collected at 6-12m intervals 
                        in the cover sequence, and every 6 to 30m in diamond 
                        drill core segments of the drill hole using single shot 
                        (Axis Mining Champ Gyro or equivalent). The single shot 
                        surveys have been validated using continuous survey 
                        to surface (Axis Mining Champ or equivalent) along with 
                        a selection of drill holes re-surveyed by an external 
                        survey contactor using a DeviGyro tool - confirming 
                        sufficient accuracy for downhole spatial recording. 
                        All collar coordinates are provided in the Geocentric 
                        Datum of Australian (GDA20 Zone 51). All relative depth 
                        (RL) information is reported in AHD +5000m. 
                        A LIDAR survey was completed over the project area in 
                        Nov 2019 which was used to prepare a DEM / topographic 
                        model for the project with a spatial accuracy of +/- 
                        0.1m vertical and +/- 0.3m horizontal. The topography 
                        is generally low relief to flat, elevation within the 
                        dune corridors in ranges between 250-265m Australian 
                        Height Datum (AHD) steepening to the southeast. Easting 
                        and Northing coordinates are provided in the Geocentric 
                        Datum of Australian (GDA20 Zone 51) and all vertical 
                        level information is reported in AHD +5000m. 
--------------------  ------------------------------------------------------------------ 
 Data spacing          Within the South East Crescent Zone, Breccia Zone and 
  and distribution      Eastern Breccia, drill hole spacing ranges from 50 by 
                        100m, to 50 by 50m within the current resource extents. 
                        Outside the resource boundary drill hole spacing ranges 
                        from 50 to 200m in lateral extent within the Breccia 
                        Zone over an area of 2km2. 
                        Isolated holes test targets away from the Havieron pipe. 
                        The data spacing 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. 
                        Samples have not been composited. 
--------------------  ------------------------------------------------------------------ 
 Orientation           Drill holes targeting the Crescent Zone are oriented 
  of data in            to intersect the steeply dipping high-grade sulphide 
  relation to           mineralisation zones at an angle of greater than 40 
  geological            degrees. As such, the drilled length of reported intersections 
  structure             is typically greater than true width of mineralisation 
                        in this Zone. Most of these holes also intersect the 
                        adjacent Breccia Zones. 
                        Drill holes targeting the Breccia Zones are oriented 
                        to intersect at angles either broadly perpendicular 
                        to the adjacent Crescent Sulphide Zones, or if drilling 
                        away from the South East Crescent Zone area, at intersections 
                        broadly perpendicular to the elongation of the ovoid 
                        breccia body. Given the lower level of understanding 
                        of the breccia geometries it is not possible to quantify 
                        the relationship between drilled and true length of 
                        reported intersections in these Zones. 
                        The attitudes of the South East Crescent Zone and Main 
                        (Northern) Breccia Zone and the variety in drilling 
                        orientations through such suggest no sample orientation 
                        related biases affect these zones. 
                        The Eastern Breccia, which is interpreted to strike 
                        north-westerly and dip steeply, is intersected almost 
                        exclusively with moderate-steep west-to-east drilling. 
--------------------  ------------------------------------------------------------------ 
 Sample security       The security of samples is controlled by tracking samples 
                        from drill rig to database. 
                        Drill core was delivered from the drill rig to the Havieron 
                        core yard every shift. On completion of geological and 
                        geotechnical logging, core processing was initially 
                        completed by Newcrest personnel at the Telfer facility 
                        but later done at the Havieron facility once it was 
                        operational. 
                        Samples were freighted in sealed bags by air and road 
                        to the laboratory, in the custody of Newcrest representatives. 
                        Sample numbers are generated directly from the database. 
                        All samples are collected in pre-numbered calico bags. 
                        Verification of sample numbers and identification is 
                        conducted by the laboratory on receipt of samples, and 
                        sample receipt advice issued to Newcrest. 
                        Details of all sample movement are recorded in a database 
                        table. Dates, Hole ID sample ranges, and the analytical 
                        suite requested are recorded with the dispatch of samples 
                        to analytical services. Any discrepancies logged at 
                        the receipt of samples into the analytical services 
                        are validated. 
--------------------  ------------------------------------------------------------------ 
 Audits or             Internal reviews by Newcrest (JV Manager) of the core 
  reviews               handling, sample preparation and assays laboratories 
                        are conducted on a regular basis by both project personnel 
                        and owner representatives and have not identified any 
                        material issues affecting the reliability of the sampling 
                        techniques and data. 
                        In the Competent Person's opinion, the sample preparation, 
                        security and analytical procedures are consistent with 
                        current industry standards and are appropriate and acceptable 
                        for the styles of mineralisation identified and will 
                        be appropriate for use in the reporting of Exploration 
                        Results and Mineral Resource estimates. No drilling, 
                        sampling or recovery factors that materially impact 
                        the reliability of the results of the drilling programme 
                        have been identified.

 Exploration               Newcrest completed six core holes in the vicinity of 
  done by other             the Havieron Project from 1991 to 2003. Greatland Gold 
  parties                   completed targeting and drilling of nine Reverse Circulation 
                            (RC) drill holes with core tails for a total of approximately 
                            6,800m in 2018. Results of drilling programs conducted 
                            by Greatland have previously been reported on the Greatland 
                            website.

 Geology                   The Havieron Project is located within the north-western 
                            exposure of the Palaeo-Proterozoic to Neoproterozoic 
                            Paterson Orogen (formerly Paterson Province), 45 km 
                            east of Telfer. The Yeneena Supergroup hosts the Havieron 
                            prospect and consists of a 9km thick sequence of marine 
                            sedimentary rocks and is entirely overlain by approximately 
                            420m of Phanerozoic sediments of the Paterson Formation 
                            and Quaternary aeolian sediments. 
                            Gold and copper mineralisation at Havieron consist of 
                            breccia, vein and massive sulphide replacement mineralisation 
                            typical of intrusion-related and skarn styles of mineralisation. 
                            Mineralisation is hosted by metasedimentary rocks (meta-sandstones, 
                            meta-siltstones and meta-carbonate) and intrusive rocks 
                            of an undetermined age. The main mineral assemblage 
                            contains well developed pyrrhotite-chalcopyrite and 
                            pyrite sulphide mineral assemblages as breccia and vein 
                            infill, and massive sulphide lenses. The main mineralisation 
                            event is associated with amphibole-carbonate-biotite-sericite-chlorite 
                            wall rock alteration. Drilling has partially defined 
                            the extents of mineralisation which are observed over 
                            a 650m by 350m ovoid area, and to depths of up to 1500m 
                            below surface.

 Drill hole                As provided in Appendix II. Refer to previous exploration 
  Information               releases for drillhole information of the previously 
                            reported intercepts highlighted in this report. 
                          ------------------------------------------------------------------------ 
 Data aggregation          Significant assay intercepts are reported as (A) length-weighted 
  methods                   averages exceeding 1.0g/t Au greater than or equal to 
                            10m, with a maximum of 5m consecutive internal dilution; 
                            and (B) length-weighted averages exceeding 0.2g/t Au 
                            for greater than or equal to 20m, with a maximum of 
                            10m consecutive internal dilution, and (C) intervals 
                            of >30g/t with no internal dilution which are greater 
                            or equal to 30 gram metres (Au_ppm x length). No top 
                            cuts are applied to intercept calculations. Refer to 
                            previous exploration releases for drillhole information 
                            of the previously reported intercepts highlighted in 
                            this report and used in the Mineral Resource Estimate.

 Relationship              Significant assay intervals reported represent apparent 
  between mineralisation    widths. Drilling is not always perpendicular to the 
  widths and                dip of mineralisation and true widths are less than 
  intercept                 downhole widths. Estimates of true widths will only 
  lengths                   be possible when all results are received, and final 
                            geological interpretations have been completed.

 Further work              Growth drilling is underway to extend the limits of 
                            the mineralised system at depth and looking to establish 
                            additional resources outside those defined to date, 
                            including extension and infill of the Eastern Breccia 
                            and drilling outside the Havieron mineralised system

(#) drilling in progress. **partial intercept, assays pending. ^updated intercept. ^^previously reported intercept.

Havieron Project, Paterson Province, Western Australia

Reporting Criteria: Intercepts reported are downhole drill width (not true width) Au >0.20ppm (0.2g/t Au) and minimum 20m downhole width with maximum consecutive internal dilution of 10m. Average grades are based on length-weighting of samples grades. Also highlighted are high grade intervals of Au >1.0ppm (1g/t Au) and minimum 10m downhole width with maximum consecutive internal dilution of 5m, and intervals of >30g/t which are greater or equal to 30 gram metres (Au_ppm x length) are tabled. Gold and copper grades are reported to two significant figures, the downhole lengths are rounded to 0.1m which may cause some apparent discrepancies in interval widths. Samples are from core drilling which is PQ, HQ or NQ in diameter. Core is photographed and logged by the geology team before being cut. Half core PQ, HQ and NQ samples are prepared for assay and the remaining material is retained in the core farm for future reference. Each assay batch is submitted with duplicates and standards to monitor laboratory quality. Total depth (end of hole) is rounded to one decimal place for reporting purposes. Collars denoted with a * show partial results, with further significant assays to be reported in subsequent exploration updates.
