NEWS RELEASE | 20 April 2023  

Rudall Exploration Results

High grade gold mineralisation intersected at depth

THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION AS STIPULATED UNDER THE UK MARKET ABUSE REGULATIONS.  ON PUBLICATION OF THIS ANNOUNCEMENT VIA A REGULATORY INFORMATION SERVICE, THIS INFORMATION IS CONSIDERED TO BE IN THE PUBLIC DOMAIN .

Greatland Gold plc (AIM:GGP; Greatland or Company) is pleased to announce the results of its 2022 drilling programme at the 100%-owned Rudall project in the Paterson Province of Western Australia.  The Ramses target is located within the Rudall tenement, 20km southeast of Greatland's flagship Havieron gold-copper project.  The single drill hole testing the Ramses target was supported by a Western Australian Exploration Incentive Scheme (EIS) grant (see RNS Announcement titled "Greatland awarded a drilling grant for Paterson province exploration project" dated 10 May 2022).

Highlights

§ Hole RAD002 intersected 18.25m @ 22.0g/t Au from 924m (uncut) to end of hole (EOH) at 942.25m, including 1m @ 393g/t Au from 926m .  Significantly, anomalous copper, silver, bismuth and arsenic assays were recorded within the broad, altered intersection

§ The hole ended due to drilling limitations and mineralisation is open at depth

§ Structural and geochemical work and a future downhole electromagnetic survey are required to refine the potential for mineralisation to extend into shallower positions within the system

Greatland Managing Director, Shaun Day, commented:

"Our recent drilling at Rudall has delivered a significant and high-grade result."

"While recognising the high-grade intercept is at depth, the strong gold mineralisation and supporting pathfinder geochemistry in consistently altered and veined basement sediments continues to highlight the outstanding prospectivity within Greatland's tenement package and the Paterson Province in general."

"These results, together with our continual improvement in understanding of the covered basement geology, stratigraphy and structure, increase our confidence in the prospectivity of the region, and our ability to vector towards intrusion related and other styles of mineralised systems on our extensive ground holdings."

Overview of the 2022 Rudall Programme

The Ramses target, within the Rudall project (Figure 1), was identified as a potential Havieron-style body from interpretation and re-modelling of regional airborne magnetic and gravity data. Following the granting of EIS funding for drill testing, a small, ground moving loop electromagnetic survey utilising an Abitibi-RMIT (ARMIT) sensor probe was completed prior to drilling in an attempt to detect a conductive body.  Results were inconclusive due to the thickness of cover. To further refine the drill target, the magnetic anomaly was forward modelled by Adelaide Mining Geophysics ( Figure 3 ). Modelling estimated cover to extend to a depth of between 300m and 700m over a 500m wide vertical roughly cylindrical body.

Diamond drill hole RAD002 was drilled to a depth of 942.25m to ensure success in penetrating through the cover into the Proterozoic basement and magnetic target zone.

Ramses Target

Drilling intersected the Permian Canning Basin sediment contact unconformity at a depth of 566m downhole (approximately 557m vertical).  The underlying target Proterozoic Yeneena sedimentary stratigraphy consisted of generally sub-horizontally bedded, fine-grained sandstones interbedded with variably calcareous, silty sandstone to limestone rich sedimentary units.

A second, angular unconformity was noted within basement rocks at 924m downhole, where barren, sub-horizontally bedded, dark, fine-grained carbonaceous shaley siltstones overlay the pale green-brown, silica-carbonate-sericite altered and mineralised sandstone package ( Figures 3 and 4 ).  Bedding in the mineralised unit below 924m displays open folding with a maximum dip of 67^o about an E-W fold axis, with a sub-vertical axial planar foliation.  Two cross-cutting vein sets, the first dipping 21^o towards the south and a steep set dipping ~70^o towards 240^o (SSW) were noted in the altered sandstones which appear linked to the gold mineralisation and alteration.  The presence of iron oxide-stained sediments at such great depth indicates potential uplift and exposure to air and water at some earlier stage.

The entire sandstone sequence below the interpreted unconformity was altered and mineralised, ( Figure 4 and Table 2 ), including several narrow intervals of significantly anomalous multi-element pathfinder elements such as bismuth, arsenic, silver and copper (Appendix 1). 

Subsequent laboratory screen fire assay check analyses for gold confirmed the single metre, high-grade assay and overall mineralised intersection tenor.  No bias between the fine fraction and coarse fraction assays in the screen fire results was noted, giving a high degree of confidence in the initial results.

Next Steps

The presence of steep dipping veining within the mineralised zone increases the potential that the mineralisation extends to the top of the basement at approximately ~550m below surface. For context, the Havieron deposit occurs at ~420m below surface.

To test this, further structural and geochemical work along with a downhole electromagnetic survey of hole RAD002 to identify any off-hole conductors, will refine the potential for the mineralisation to extend to a shallower position within the basement.

About Greatland

Greatland is a mining development and exploration company focused primarily on precious and base metals. 

The Company's flagship asset is the world-class Havieron gold-copper project in the Paterson Province of Western Australia, discovered by Greatland and presently under development in joint venture with ASX gold major, Newcrest Mining Limited.

Havieron is located approximately 45km east of Newcrest's existing Telfer gold mine. The box cut and decline to the Havieron orebody commenced in February 2021.  Development continues to accelerate with record advancement achieved in the December 2022 quarter.  Havieron is intended to leverage the existing Telfer infrastructure and processing plant. Access to Telfer will de-risk the development, reduces capital expenditure and lowers the project's carbon footprint.

Greatland has a proven track record of discovery and exploration success and is pursuing the next generation of tier-one mineral deposits by applying advanced exploration techniques in under-explored regions.  Greatland has a number of exploration projects across Western Australia and in parallel to the development of Havieron is focused on becoming a multi-commodity miner of significant scale.

JORC Code, 2012 Edition - Table 1

Section 1 Sampling Techniques and Data

Criteria	JORC Code Explanation	Commentary
Sampling techniques	§ Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation) § Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used § Aspects of the determination of mineralisation that are Material to the Public Report § In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information	§ A multi-purpose RC/DD Drill rig was used to drill mud rotary pre-collars from surface to competent ground or through the cover sequence with a diamond tail completed in competent ground/basement, to obtain representative samples in an industry standard method § Greatland diamond samples comprise half core material in generally 1m lengths (NQ and HQ diameter core). All basement and the basal 20m of the Permian cover was sampled where intersected with Diamond or RC drilling. Core was cut using an automated core-cutter At Greatland's Port Hedland core shed laydown § No regular sampling was completed for mud rotary drilling as the sample is considered contaminated § Cutting of core adjacent to the downhole orientation line or, where un-oriented and possible, orthogonal to visible geological structures such as bedding, foliation; ensures sample representivity § 50% of the assayed core was sent to DMIRS Core Library as part of the EIS protocols.  Greatland retained quarter core for future check logging, re-sampling and QA/QC.  100% of the un-sampled Permian cover sequence core was sent to DMIRS Ground EM Data Collection: In September 2022, Vortex Geophysics, supervised by NewExCo, on behalf of Greatland Gold, undertook the collection of 5.2-line kilometres of slingram configured, Moving Loop ground electromagnetic data, over the Ramses target. Moving Loop Data collection specifications are: - 200m square transmitter loops - VTX-100 transmitter - Monex GeoScope ARMITv4 Sensor - Monex Geoscope Terra TEM24 receiver - Base frequency 1.0 Htz - Duty cycle 50% - Off time ramp 1 msec - 6 channels; full time series; 24 Bit ADC Precision - Station spacing: 100m; on 2 x 400m spaced lines.
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)	§ mud-rotary pre-collars were followed by HQ then NQ diamond drill core to EOH § The core is oriented using a Reflex mark III tool, nominally every core run (around 3 or 6m)
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	§ Recovery is measured on core and reconciled against driller's depth blocks in each core tray. Basement core recovery is typically around 100% § No specific measures have been taken to maximise recovery, other than employing skilled drillers § Half core cut at a consistent spacing from orientation lines assists in sample representivity § No relationship between recovery and grade has been observed
Logging	§ Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies § Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography § The total length and percentage of the relevant intersections logged	§ The logging is of sufficient quality to support a Mineral Resource estimate, and comprises a combination of quantitative and qualitative features. The entire hole is logged § Geological logging recorded qualitative descriptions of lithology, alteration, mineralisation, veining, and structure including orientation of key geological features § Geotechnical measurements were recorded including Rock Quality Designation (RQD) and solid core recovery § Magnetic susceptibility measurements were recorded every metre using a KT20 machine § The bulk density of selected drill core intervals was determined at site on selected whole core samples § Digital data was recorded on site and stored in an SQL database § All drill cores were photographed, prior to cutting and sampling the core § The ground EM survey data was interpreted and reported by expert geophysical Consultants NewExCo
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	§ Drill samples were freighted by road to the laboratory. All core is cut with a core saw, and quarter core sampled to the laboratory § The samples are assayed at Intertek (Perth, WA)  Samples were dried at 105oC, and the bulk of the samples pulverised (using an LM5) to produce a pulped product. Oversize primary samples were crushed and a 3kg subsample then milled with the LM5 mill § Sub sampling is reduced to a minimum by using total sample pulverisation prior to sub sampling wherever possible § The sample sizes (1-1.5kg) are considered appropriate for the material being sampled
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 (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.	§ The samples were assayed for Au by a 50gm fire assay and for a multi-element scan using 4 acid digest and MS and OES finish for pathfinder and lithogeochemical elements. The assays are considered total rather than partial § Greatland QA/QC procedures include using reference samples and field duplicate samples every 25 samples, in addition to the laboratories in- house QA/QC methods § Analysis of the 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
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	§ No twinned holes have been completed § All data entry procedures, including original logging, sample depth selection for sampling and recording of sample numbers are recorded digitally in an electronic database § There are no adjustments to assay data, other than below detection samples are reported at negative one half the detection limit § Extreme high grade Au (>100g/t Au) was noted in the initial fire assay results.  The entire mineralised core interval from 920m to EOH was re-assayed at Intertek by Screen Fire Assay to ensure the accuracy of the original fire assay results.  The fine fraction (<75um) is fire assayed in duplicate and all gold in the coarse fraction is recovered by FA.  The total assay grade of the coarse and fine fractions are then calculated by weighted average. Results of the screen fire assays are considered consistent with the original fire assays and the fire assays are reported for consistency
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	§ Drill collar locations were surveyed using hand held GPS. RL's were collected with the same GPS § Drill rig alignment was attained using fixed gyro instrument. § Downhole survey was collected every 30m in diamond drill core segments of the drill hole using a single shot Axis Mining Champ Gyro § The topography is generally low relief to flat, elevation within the dune corridors in ranges between 250-265m AHD steepening to the southeast § All collar coordinates are provided in the Geocentric Datum of Australian (GDA94 Zone 51). All relative depth information is reported in Australian Height Datum (AHD)
Data spacing and distribution	§ Data spacing for reporting of Exploration Results § Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied § Whether sample compositing has been applied	§ Drill holes are individual exploration holes targeting specific targets, and are not part of a grid pattern as such no mineral resource or reserve is stated § No sample compositing has been applied
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 is oriented at various angles to folded layering, and to identified sulphide mineralised structures. The relationship to possible mineralised structures is unknown at this stage
Sample security	§ The measures taken to ensure sample security	§ The security of samples is controlled by tracking samples from drill rig to database § Entire core samples are delivered by company personnel to a freight company in Port Hedland for delivery by road freight to the assay lab in Perth, where the core is cut and sampled
Audits or reviews	§ The results of any audits or reviews of sampling techniques and data	§ No audits or reviews have been completed

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	§ The Rudall tenement E45/5533 is 100% owned by Greatland Pty Ltd § The tenement is subject to a Land Access Agreement  with Jamukurnu-Yapalikurnu Aboriginal Corporation
Exploration done by other parties	§ Acknowledgment and appraisal of exploration by other parties	§ There is no known previous work on the tenement
Geology	§ Deposit type, geological setting and style of mineralisation	§ Exploration is for intrusion related and orogenic, structurally controlled Au-Cu deposits similar to Telfer, Havieron and Winu, all located in Neo-Proterozoic Yeneena Group sediments of the Paterson Province, Western Australia
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	§ Greatland drill hole collar details are listed in - Table 1 and anomalous results in Table 2
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 § 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	§ No economically significant results have been reported, and no data aggregation methods have been applied § Where anomalous results are quoted (Table 2) the samples have been selected as follows: -  Au >0.1ppm; or -  Ag >2ppm; or -  Cu >500ppm; or -  Bi >1ppm; or -  Pb >200ppm; or -  Zn >1000ppm -  with a maximum consecutive internal waste of 3m § individual assays and their interval widths for reported anomalous intervals are displayed in appendix 1
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')	§ No economically significant results are reported, and there is no known relationship between reported widths and the geometry of any mineralisation § All intercepts are reported downhole as true width is not known
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	§ Maps are provided in Figures 1-2. No significant discovery is reported
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	§ The reporting is considered balanced
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	§ No other substantive exploration data other than that provided in the figures
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 sensitive	§ Downhole EM of RAD002 is planned for 2023
