Initial Scallywag Drill Results and New Targets Identified
First three drill holes at Scallywag intersect prospective target lithologies and pathfinder element anomalism
Multiple new targets identified across Scallywag licence (including Teach, Swan, A34, A35 and A36) from analysis of Airborne EM survey data and regional aeromagnetics
Greatland Gold plc (AIM:GGP), the precious and base metals exploration and development company, announces the results of the first three drill holes completed at its 100% owned Scallywag licence. In addition, the Company has identified multiple new targets at Scallywag following analysis of results of a Heliborne Electromagnetic ("EM") survey conducted last year and further geological interpretation of regional aeromagnetics.
Exploration work at Scallywag is focussed on the discovery of intrusion related gold-copper deposits such as Havieron, Telfer and Winu. Greatland completed seven drill holes at Scallywag in the second half of calendar 2020, testing targets at the Kraken, London and Blackbeard prospects. Assay results have been received for the first three holes (LOD001, KRD001 and BLD001) and are reported here today.
Highlights of Drill Results
· The assay and logging results from the first three drill holes of the 2020 programme suggest the holes have intersected prospective target lithologies and pathfinder element anomalism associated with quartz-pyrite vein arrays.
· Peak gold intersected was 1m @ 0.25g/t from 398m (LOD001) and peak copper intersected was 1m @ 1,105ppm from 461m (BLD001), with anomalous levels of other pathfinder elements including silver and bismuth also detected.
New Targets Identified
· Analysis of results from Heliborne EM geophysical survey conducted last year has identified multiple new conductors within the Scallywag licence including:
· Swan - a strong, deep AEM conductor located in an interpreted fold structure developed adjacent to, or truncated by, a crustal scale fault.
· A34, A35 and A36 - discrete segments of strongly conductive material coincident with positive gravity response.
· In addition, ongoing geological interpretation assisted by drill information and regional aeromagnetics has identified a new target within the Scallywag licence named "Teach", located 3km SSE of the Blackbeard prospect.
Next Steps
· Follow up drilling is planned during the 2021 field season to test for further development of brecciated and mineralised lithologies, in particular along strike at the newly defined Teach target.
· Drilling of the new EM targets identified is also planned for the 2021 field season, following the collection of ground EM data which is scheduled to commence in March 2021.
· A more detailed evaluation of drill results will be undertaken on receipt of all analytical data from the 2020 field season and targets will be further assessed and ranked for drill testing.
Gervaise Heddle, Chief Executive Officer of Greatland Gold plc, commented: "Greatland's first drilling campaign at Scallywag has identified pathfinder element anomalism and provides us with valuable geological information which we expect to use in further assessing and ranking drill targets across the Scallywag licence. In addition, further analysis of geophysical data has built on our existing understanding to generate a number of new compelling targets. We look forward to progressing with further drill testing at Scallywag during 2021, particularly at the new Teach target and other high-priority targets identified by the EM survey conducted last year."

Further Information on Initial Drilling Results from Scallywag
The Company completed a total of seven holes for 3,761m at Scallywag during the 2020 field season, testing targets at the Kraken, London and Blackbeard prospects. Exploration work at Scallywag is focussed on the discovery of intrusion related gold-copper deposits such as Havieron, Telfer and Winu.
The 2020 Scallywag drill programme was designed to test a series of Induced Polarisation ('IP'), magnetic altered or demagnetised geophysical targets located around the closure and limbs of the Scallywag Syncline, a tight fold structure located to the west of the Havieron discovery. The Syncline folds a package of Puntapunta Formation calc-silicates and overlying Wilki Formation siliciclastic metasediments, with a prominent magnetic anomaly marking the contact between the two units. The Puntapunta Formation sediments host the Havieron Au-Cu system on the east limb of the Scallywag Syncline, some 8.5km east south east of the fold nose or closure of the Syncline.
Three targets have been partially tested by seven drill holes, of which results for three drill holes are reported today: LOD001 on the London prospect, KRD001 on the Kraken prospect, and BLD001 on the Blackbeard prospect for 1,919m of drilling. Samples from a further four drill holes for 1,842m are currently with assay laboratories, which are experiencing high sample deliveries resulting in significant delays in return of results.
London
The London target comprises an IP anomaly located on the edge of an interpreted granite body (gravity low) displaying potential demagnetisation or apparent truncation in the magnetic Wilki Formation sedimentary unit intruding along the magnetic east limb of the Scallywag Syncline. The IP anomaly could represent skarn type mineralisation on or near the edge of the interpreted granite body.
LOD001 was drilled to a total depth of 576.6m and intersected basement Wilki Formation quartz rich siliciclastic sediments below 291.3m of Permian cover. The drillhole intersected granite between 552.7m to 571.4m downhole with anomalous Ag-Cu-Pb-Zn assays reported from samples in the granite near the upper contact with the sediments, associated with a stockwork of thin quartz veins and disseminated pyrite. Peak values were 0.9ppm Ag, 565 ppm Cu, 571 ppm Pb and 1047ppm Zn, with some anomalous Bi and Mo reported, including an interval of 4m averaging 21ppm Mo from 561m. Peak gold intersected was 1m @ 0.25g/t from 398m hosted in quartzite with a narrow quartz- pyrite-hematite vein. Anomalous values are reported in Appendix I.
Sulphide concentrations in the hole are not considered sufficient to generate the IP response. The discrete granite sill intersected in the drilling is not considered to have caused the demagnetisation and/or displacement of the magnetic anomaly along the Wilki-Puntapunta contact, and there may be more sills or alteration along this contact that have not been tested by LOD001. A further drill hole is warranted to test for demagnetisation or displacement of the contact.
Kraken
The Kraken target comprises a combined magnetic and IP anomaly located near the nose of the Scallywag Syncline.
Hole KRD001 was drilled to a total depth of 748.5m and intersected basement Puntapunta Formation calc-silicate sediments including marbles and interbedded siltstones beneath the base of Permian at 195.4m, staying in Puntapunta to end of hole.
Anomalous pathfinders are reported over several intervals, including copper, silver, bismuth, tellurium and lead, with anomalous gold to 76ppb over 0.5m locally. Maximum values (with coexisting elements) are reported in Table 1 (with all anomalous results listed in Appendix I). The higher Au and Ag values around 220 to 224.5m are associated with discrete narrow steep south west dipping quartz-pyrite veins with silica-hematite alteration haloes. There is a distinct arsenic anomalous zone (>10ppm As, maximum 36.5 ppm As) hosted within calcite rich marble between 335-345m. In detail the As appears associated with disseminated sulphide hosted in thin siltstone beds between calcite rich marble bands.

KRD001 intersected minor magnetic material and sulphide bearing material which may be sufficient to generate the IP response.
Blackbeard
The Blackbeard target comprises an IP anomaly located in the core of the Scallywag Syncline, around 1km southeast of the Kraken prospect. The Blackbeard IP anomaly could represent sulphide mineralisation at depth hosted in Wilki Formation siliciclastic sediments above the magnetic Wilki- Puntapunta Formation contact.
BLD001 was drilled to total depth of 593.85m and intersected basement Wilki Formation siliciclastic sandstone and siltstone sediments below base of Permian at 275.95m downhole.
No significant sulphides were reported from the drilling however anomalous pathfinders were located, in particular Bi and locally some Ag. Peak copper result in BLD001 was 1m @ 1,105ppm from 461m. Anomalous results are listed in Appendix I.
BLD001 did not intersect significant sulphide bearing material considered sufficient to generate the IP response.
Other Drilling from 2020 Field Programme
Samples from a further four drill holes for 1,842m are currently with assay laboratories who are experiencing high sample deliveries resulting in delays to receipt of results.
The four drill holes are:
• LOD002 drilled SE of LOD001 testing a deep IP target;
• LOD003 drilled between Kraken and Blackbeard, testing an IP target;
• KRD002 a partial scissor hole to KRD001 and testing the Kraken target; and
• KRD003, testing a gravity anomaly on the edge of the Kraken target in the nose of the Scallywag Synform.
Summary of Drilling Results and Conclusions
The assay results and geological information from the first three drill holes of the 2020 programme intersected prospective lithologies and pathfinder element anomalism (Ag, Cu, Bi), associated with quartz-pyrite vein arrays. Follow up drilling is recommended to test for further development of brecciated and mineralised lithologies, in particular along strike at the newly defined "Teach" target, described below.
A more detailed evaluation of drill results will be undertaken on receipt of all analytical data from the 2020 field season and targets will be further assessed and ranked against the multiple targets within the Company's 100% owned ground and Farm-in/JV areas. Drilling of the Company's many existing targets and newly generated targets identified in the recent airborne EM survey is planned to resume in the current field season.
New Magnetic Target - Teach
Ongoing geological interpretation assisted by drill information and regional aeromagnetics has identified a new target within the Scallywag licence named Teach. Teach is located 3km south-south east of the Blackbeard prospect, comprising a series of structures with associated magnetic anomalism piercing the east limb of the Scallywag Anticline. Teach may represent primary mineralisation along the Scallywag Synform providing possible distal mineralisation and pathfinder element response as seen in LOD001, KRD001 and BLD001.
New Airborne Electromagnetic Targets
During the 2020 field season Greatland acquired an Airborne Electromagnetic ('AEM') geophysical survey covering the Scallywag, Black Hills and the western part of the Paterson Range East exploration licenses. The survey was designed to:
· Assist in the detection of Havieron, Winu and Telfer style Au-Cu deposits beneath cover;
· Detect basement conductor's related to accumulation of massive sulphides and/or associated alteration;
· Map structure and stratigraphy, particularly in non-magnetic sedimentary packages, similar to the host rocks at Telfer and Havieron; and
· Map basement topography and depth of cover.
Within the Scallywag licence the survey comprised 492 line kilometres of AEM collected by New Resolution Geophysics using their helicopter borne 25Hz 'Xcite' system. Line spacing was 200m. The survey has identified nine new conductors within Scallywag, seven of which may be the response of basement conductors with several described below:
· Swan - a strong, deep AEM conductor located in an interpreted fold structure developed adjacent to, or truncated by, a crustal scale fault; and
· A34, A35 and A36 - discrete segments of strongly conductive material coincident with positive gravity response.
Historic shallow drilling is present over the Swan, A34, A35 and A36 targets however these historic holes are considered ineffective due to cover depth.
Interpretation and ranking of bedrock AEM conductors is ongoing, including integration with other available geological, geochemical and geophysical datasets. Several targets warrant drill testing after ground EM follow-up work to confirm conductor location and tenor.
Additional drill hole information is presented in Appendices I, II, III and IV.

Notes for Editors:
Greatland Gold plc is a London Stock Exchange AIM-listed (AIM:GGP) natural resource exploration and development company with a current focus on precious and base metals. The Company has six main projects; four situated in Western Australia and two in Tasmania.
In March 2019, Greatland signed a Farm-in Agreement with Newcrest Operations Limited, a wholly-owned subsidiary of Newcrest Mining Limited (ASX:NCM), to explore and develop Greatland's Havieron gold-copper deposit in the Paterson region of Western Australia. The Havieron Project is operated by Newcrest under a Joint Venture Agreement with Greatland Gold plc. Newcrest can earn up to a 70% joint venture interest through total expenditure of US$65 million and the completion of a series of exploration and development milestones in a four-stage farm-in over a six year period that commenced in March 2019. Newcrest may acquire an additional 5% interest at the end of the farm-in period at fair market value.
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.
Greatland is seeking to identify large mineral deposits in areas that have not been subject to extensive exploration previously. It is widely recognised that the next generation of large deposits will come from such under-explored areas and Greatland is applying advanced exploration techniques to investigate a number of carefully selected targets within its focused licence portfolio.
The Company is also actively investigating a range of new opportunities in precious and strategic metals and will update the market on new opportunities as and when appropriate.

JORC Code, 2012 Edition - Table 1 report template
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)
· 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.
· Greatland samples comprise half core material in generally 1m lengths (NQ core) or 0.5m lengths (in PQ core). All basement and the basal 20m of the Permian cover was sampled. Core was cut using an automated core-cutter.
· Historical drilling- no sampling reported
Sampling techniques
· Xcite Airborne EM Program
· An Airborne Electromagnetic and Magnetic Survey was undertaken in 2020 by New Resolution Geophysics Australia Pty Ltd (NRG), using a Time Domain Airborne Electromagnetic (Excite TM ) time‐ domain, helicopter borne electromagnetic system.

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).
· RC precollars were followed by PQ then NQ diamond drill core to EOH.
· The core is oriented using a Reflex mark III tool, nominally every core run (around 6m).
· Historical drilling- see Appendix IV.
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 along orientation lines assist in sample representivity;
· No relationship between recovery and grade has been observed;
· Historical drilling- no sampling reported
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.

· Whether sample compositing has been applied.
· Drill holes are individual exploration holes targeting specific targets, and are not part of a grid pattern;
· Not applicable in early stage exploration;
· No sample compositing has been applied;
· Historical drilling has comprised generally vertical holes on a nominal 400m x 400m grid - no sampling reported
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 mineralized structures. The relationship to possible mineralized structures is unknown at this stage.
· Historical drilling- no sampling or structure reported
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.
· Historical drilling- not recorded
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 listed in the preceding section also apply to this section.)

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 Scallywag tenement E45/4701 is 100% owned by Greatland Pty Ltd.
· The tenement is subject to a Land Access Agreement (LAA) with Western Desert Lands Aboriginal Corporation;
Exploration done by other parties
· Acknowledgment and appraisal of exploration by other parties.
· No previous on ground exploration has been completed in the vicinity of the reported Greatland drilling.
· Historical work comprised shallow drilling in the north end of the Scallywag tenement (72 generally aircore holes, averaging 47.3m deep, 4 RAB holes (average 68m) and 9 RC holes (average 96.3m) by companies including Newcrest and Normandy Exploration Limited.
· Historical reports (WAMEX "A" numbers) are referenced in Appendix IV
Geology
· Deposit type, geological setting and style of mineralisation.
· Exploration is for intrusion related 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:
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 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 Appendix II and anomalous results in Appendix i.
· Historical drill hole collar details are listed in Appendix IV. No results are reported.
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 significant results have been reported, and no data aggregation methods have been applied.
· Where anomalous results are quoted (Appendix III) the samples have been selected as follows (note that the database comprises 1495 samples):
o Au >0.1ppm (2 samples);
o Ag >2ppm (4 samples);
o Cu >500ppm (6 samples);
o Bi >5ppm (16 samples;
o Pb >200ppm (16 samples) and
o Zn >1000ppm (2 samples)
· Historical drilling- no sampling reported.
Relationship between mineralis-ation 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 significant results are reported, and there is no known relationship between reported widths and the geometry of any mineralization.
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 Figure 1 and 2. No significant discovery is reported and no sections are provided.
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.
· Further drilling in the Scallywag Anticline- Syncline pair is planned for 20121, in addition to drilling of AEM targets including the Swan target, closer to Black Hills to the north west of the existing drilling.
