Scallywag Drill Results 
 
Results provide further evidence of the potential for intrusion-related mineralised systems at Scallywag, confirming the area's prospectivity and meriting further exploration 
 
Greatland Gold plc (AIM:GGP), the precious and base metals exploration and development company, announces the results of the remaining four drill holes from the 2020 drilling campaign at its 100% owned Scallywag licence. The Company has identified multiple new targets to conduct further drill testing. Greatland's 2021 drilling in the Paterson is expected to commence in the coming weeks. 
 
The Scallywag drill programme reported here is the first stage of an extended drilling programme across Greatland's 100% licences and the Juri Joint Venture. During 2020 a total of seven drill holes were completed for 3,761m testing targets at the Kraken, London and Blackbeard prospects. Assay results have now been received for the remaining four holes (LOD002, LOD003, KRD002 and KRD003) in addition to the results of the first three holes released on 20 January 2021.
 
Highlights of 2020 Drill Results
 
§ Drill results provide further evidence of pathfinder element anomalism potentially distal to intrusion-related mineralised systems, and potentially along strike of the current drilling 
§ At the Kraken target, assay and logging confirm the intersection of prospective target lithologies and pathfinder element anomalisms including silver, copper, bismuth and lead  
 
New Targets Identified
 
§ Ongoing geological interpretation, assisted by drill information and regional aeromagnetics, has identified multiple new targets within the Scallywag licence
§ New targets include "Architeuthis", a 600m long magnetic anomaly located 1km north of Kraken and 9km north-west along strike of Havieron, and which may represent primary mineralisation along the Scallywag Synform 
 
High Grade Anomaly
 
§ At the London target, initial sample results reported very high-grade intercepts of silver, copper and tungsten results (872ppm Ag, 1137ppm Cu and >2000ppm W) in the interval 349.0 - 350.0m in LOD003 
§ These results were suspected to be contamination. Accordingly, prior to public release, check resampling and analysis was undertaken of washed 1/4 core and the results confirmed (Appendix II, "Check" sample phase results). Notwithstanding the confirmation, it remains probable that the interval may be caused by contamination and not representative of the rock mass. The Company intends to confirm whether this may be the result of downhole contamination with follow up drilling scheduled for the upcoming drill programme
 
Next Steps
 
§ A staged exploration programme is set to methodically drill test a series of targets based on modern geological, gravity, magnetic and recently collected airborne EM datasets
§ Targets within the 100% Scallywag licence include the Swan, Teach and Architeuthis. Targets within the Juri JV include the existing Goliath, Outamind, Los Diablos and Parlay, plus newly defined AEM targets within the Black Hills area, and Tama, N5 and A9 in the Paterson Range East area
§ Drilling is expected to be ongoing throughout the 2021 and 2022 field seasons
 
Shaun Day, Chief Executive Officer of Greatland Gold plc, commented: 
 
"We may only be in the first stages of an extensive drilling programme, yet these results provide further evidence that the Scallywag licence is prospective for intrusion-related mineralised systems. In particular, it is very pleasing that initial targets have once more intersected pathfinder elements associated with systems seen nearby at Havieron and Telfer, and regionally at Winu.  
 
"Greatland has established a proven approach to exploration that brought it much success at Havieron: drill selective targets, analyse the information and refine targets to unlock value from our projects. With these encouraging initial drill results, we now have a significantly enhanced understanding of Scallywag's geology and have been able to identify multiple compelling targets that merit follow-up drilling in the coming weeks and months, particularly Swan, Teach and Architeuthis. These will form an important part of the comprehensive exploration campaign we are conducting across our 100% licences and our Juri Joint Venture."

Further Information on 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 calcareous sediments and overlying Wilki Formation siliciclastic sediments, 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 tested by seven drill holes, of which results for the last four drill holes are reported today: KRD002 and KRD003 on the Kraken prospect, and LOD002 and LOD003 around the London prospect, for 1,842m of drilling. Results for the first three drill holes (BLD001, KRD001 and LOD001) were reported in January 2021 ("Initial Scallywag Drill Results and New Targets Identified", dated 20/1/2021).
 
Kraken
 
The Kraken target comprises a combined magnetic and IP anomaly located near the nose of the Scallywag Syncline.
 
Designed to test the Kraken magnetic anomaly hole, KRD002 was drilled to a total depth of 504.5m, intersecting Wilki Formation quartz rich sediments overlying Puntapunta Formation calcareous sediments beneath the base of Permian at 256.8m downhole (all depths are reported as downhole depths). The magnetic anomaly is sourced in the basal Wilki and upper Puntapunta calcareous rocks. No significant gold or copper intersections are reported, although anomalous pathfinder elements (including silver, bismuth, copper and lead) are reported locally. Anomalous results are listed in Appendix I.  The maximum gold assay of 0.112ppm Au over 0.5m from 249m is hosted in the Permian cover.
 
Holes KRD003 was drilled to a total depth of 468.8m, testing the nose of the Scallywag Syncline, and intersected basement Puntapunta Formation calcareous sediments including magnetic units, beneath the base of Permian at 231.3m. Anomalous results are listed in Appendix I.      
 
London
 
The London target comprises an IP anomaly located on the edge of an interpreted granite body (gravity low) intruding along the magnetic east limb of the Scallywag Syncline and displaying potential demagnetisation or apparent truncation of the magnetic Wilki Formation sedimentary unit. The IP anomaly could represent skarn type mineralisation on or near the edge of the interpreted granite body.  
 
LOD002 was drilled to a total depth of 414.9m and intersected basement Wilki Formation quartz rich siliciclastic sediments below 307.1m of Permian cover. No anomalous results were reported.
 
LOD003 was drilled in the core of the Scallywag Syncline, testing an IP target near the interpreted axial plane of the Syncline.  The drill hole intersected Wilki Formation sediments below base of Permian at 284.7m. Initial sample results reported very high silver, copper and tungsten results (872ppm Ag, 1137ppm Cu and >2000ppm W, as listed in Appendix II, "Initial" sample phase results) in the interval 349.0- 350.0m, hosted in quartzite but including a 10cm interval of clay, apparently located at the end of a drill run.
 
There is a risk that this high-grade intercept is downhole contamination. Accordingly, prior to public release, check re-sampling and analysis was undertaken of washed 1/4 core. This re-sampling confirmed the very high silver, copper and tungsten results (Appendix II, "Check" sample phase results), but with the high-grade sample now restricted to the interval of clay postulated to be at the end of the drill run. It is probable that this material is contamination. The silver-copper-tungsten metal association can be typical of drilling tools with tungsten carbide teeth and silver solder sourced from a broken drill bit introduced into the drill hole. Therefore, the interval may not be representative of the rock mass. The Company intends to confirm whether this is actual mineralisation, or a result of downhole contamination, with a follow-up drill hole during the 2021 field season.
 
Summary of Drilling Results and Conclusions
 
The assay results from the four holes presented above are consistent with the first three drill holes, intersecting prospective lithologies (Puntapunta Formation) and pathfinder element (silver, copper and bismuth) anomalism, potentially the distal signature of intrusion related mineralised systems. Follow-up drilling is recommended to test for further development of brecciated and mineralised lithologies, in particular along strike at the "Teach" target, and at the newly defined "Architeuthis" magnetic target, described below.
 
These results 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, including targets identified in the 2020 airborne EM survey, is planned to commence in the coming weeks.
 
New Magnetic Target "Architeuthis" and Future Drilling Plans 
 
Ongoing geological interpretation, assisted by drill information and regional aeromagnetics, has identified a new target within the Scallywag licence named "Architeuthis". Located in the hinge of the Scallywag Syncline, Architeuthis comprises an elongate, probably tabular north east trending and west south west dipping magnetic anomaly, around 600m long, hosted in Puntapunta Formation rocks. The anomaly is in a similar stratigraphic position to Havieron but located around 9km to the north west along strike. The magnetic anomaly has a footprint of around 600m x 150m. Architeuthis may represent primary mineralisation along the Scallywag Synform providing the possible distal mineralisation and pathfinder element response as seen in the 2020 Scallywag drilling.
 
Additional drill hole information is presented in Appendices I, II, III and IV. Drill hole collar locations are shown in Figure 1.
 
The Scallywag drill programme comprises the first stage of an extended drilling programme across Greatland's 100% Scallywag licence and the Juri Joint Venture (Greatland 75%; Newcrest 25% with the right to earn 75%). Greatland's future work comprises a staged exploration programme designed to methodically drill test a series of targets based on modern geological, gravity, magnetic and recently collected airborne EM datasets. Targets within the 100% Scallywag licence include the Swan, Teach and Architeuthis targets. Targets within the Juri JV include the existing Goliath, Outamind, Los Diablos and Parlay, plus newly defined AEM targets within the Black Hills area, and Tama, N5 and A9 in the Paterson Range East area. Drilling is expected to be ongoing through the 2021 and 2022 field seasons.

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's flagship asset is the world class Havieron gold-copper deposit in the Paterson region of Western Australia. This asset is held in joint venture with Newcrest Mining Ltd. Havieron is located approximately 45km east of Newcrest's Telfer gold mine, processing plant and existing infrastructure.
 
The box cut and decline to develop the Havieron ore body was commenced in February 2021. In addition, a substantial ongoing growth drilling programme is presently underway at Havieron which is being undertaken in conjunction with preparation of a Pre-Feasibility Study. The PFS is expected to be released in late calendar 2021.
 
The Joint Venture Agreement includes tolling principles reflecting the intention of the parties that, subject to positive decision to mine, the resulting joint venture mineralised material will be processed at Telfer.
 
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 actively investigating a range of new opportunities in Australia for precious and strategic metals.

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) 
·     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.


·     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.

·     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.).


·     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

·     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;

·     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) fracture frequency, solid core recovery and qualitative rock strength measurements;
·   Magnetic susceptibility measurements were recorded every metre using a KT20 machine;
·   The bulk density of selected drill core intervals was determined at site on whole core samples.

·     Drill core samples were freighted by road to the laboratory. All core is cut with a core saw, and half core sampled;
·     The samples are assayed at Intertek (Perth, WA).  Samples were dried at 105oC, and the bulk of the samples pulverised (using 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 minimum by using total sample pulverization prior to sub sampling wherever possible;
·     The sample sizes (2-3kg) are considered appropriate for the material being sampled;
·     Historical drilling- no sampling reported.

·     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.


·     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;

·     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;
·     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.

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




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 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 V.




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 IV and anomalous results in Appendix I.
·     Historical drill hole collar details are listed in Appendix V. No results are reported.




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.


·     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 1047 samples):
o  Au >0.1ppm (1 samples);
o  Ag >2ppm (1 samples);
o  Cu >500ppm (4 samples);
o  Bi >5ppm (16 samples);
o  Pb >200ppm (1 samples) and 
o  Zn >1000ppm (No samples)
·     Historical drilling- no sampling reported.




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').


·     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. 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 (e.g. 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 2021, in addition to drilling of AEM targets including the Swan target, closer to Black Hills to the north west of the existing drilling.
