Exploration Update - Firetower Drill Results

Broad widths of gold mineralisation intersected at Firetower prospect

Greatland Gold plc (AIM:GGP), the precious and base metals exploration and development company, is pleased to announce that initial results from diamond drilling at the Company's 100% owned Firetower project in Tasmania, Australia confirm the presence of broad widths of gold mineralisation.

The current systematic, grid-based drilling programme comprises approximately 15 diamond holes with depths from 50m to 250m, for a total of approximately 2,000 metres. The programme is designed to test the main zone of mineralisation at Firetower and additional holes will test a previously undrilled area at Firetower East where new targets were identified by last year's 3D Induced Polarisation ("3DIP") survey.

Analytical results have been received for the first six diamond holes at Firetower and are reported in this announcement.

Highlights of Drill Results

·    Results received to date confirm the presence of broad widths of gold mineralisation at the Firetower prospect.

·    Best initial results include:

o  54.5m at 1.36g/t Au from surface (0m) (2019FTD001), including

§ 5m at 5.41g/t Au from 45m

o  29m at 0.78g/t Au from 78m (2019FTD003), including

§ 5m at 2.54g/t Au from 92m

o  5m at 8.72g/t Au from 81m (2019FTD004), including

§ 2m at 21.2g/t Au from 81m

o  27m at 0.46g/t Au from 43m (2019FTD005)

o  23m at 0.53g/t Au from 50m (2019FTD006)

·    Two drill holes (2019FTD001 and 2019FTD006) ended in or near mineralisation and these holes may be extended in order to test for additional mineralisation at depth.

·    Drilling activities are ongoing and further assay results are awaited at Firetower as well as for drill holes designed to test the previously undrilled target at Firetower East. 

Gervaise Heddle, Chief Executive Officer, commented: "We are pleased by the initial results from our ongoing drill campaign at Firetower which confirm the presence of broad widths of gold mineralisation. This is a promising start as these early results highlight potential depth extensions and good continuity of mineralisation between sections drilled to date. We look forward to providing further updates over the coming weeks, including results from drilling at the previously untested Firetower East prospect."

In June 2019 Greatland commenced drilling at the Firetower project with two key objectives: a) to systematically test strike continuity and potential depth extensions of mineralisation at Firetower as guided by 3DIP inversions; b) to test the 3DIP chargeability response along strike at the Firetower East prospect, in an area previously undrilled, and determine its spatial relationship to mineralisation.

Overview of the Firetower Project

The Firetower project is located in central north Tasmania, Australia, and covers an area of 62 square kilometres. The project lies in the eastern parts of the highly mineralised Mt Read volcanic rocks which host major polymetallic (zinc, lead, gold) deposits such as Hellyer and Roseberry, and copper deposits such as Mt Lyell, and the Henty gold mine which has produced over 1.25m oz since 1996.

The 100% owned Firetower project includes the prospects of Firetower, Firetower West, Firetower East and the strike extensions of prospective stratigraphy. The Firetower prospect has significant gold mineralisation from surface up to 30g/t while the mineralised system at Firetower West shows copper to 1.34% and silver to 2.6g/t. Both prospects remain open along strike and at depth.

Gold mineralisation at Firetower was first located in the late 1970s but this was not followed up until the early 1990s with reconnaissance drilling. More modern exploration by Greatland and JV partners has included soil geochemistry, geophysics and diamond drilling. Drilling to date has, in general, tested approximately 250m of strike at the main Firetower prospect.

The current diamond drilling programme is being carried out on systematic north-south traverses across the main mineralised zone at the Firetower prospect. A primary objective is to determine strike continuity and depth extensions as guided by 3DIP inversions. The programme comprises approximately 15 holes with depths from 50m to 250m. Holes are angled at 60 degrees to provide coverage across each section and it is expected that approximately 2,000m of drilling will be completed. Spacing between drill traverses is a nominal 25m.

The main zone of gold mineralisation at the Firetower prospect is spatially associated with an IP chargeability response. The IP response will also be tested along strike and at depth during the current programme at the Firetower East prospect which is located approximately 500m east of the Firetower prospect. The IP response at Firetower, as established by both 3DIP (2018) and gradient array (2002) surveys, extends across approximately 3km of strike.

Analytical results have been received for the first six diamond holes at Firetower and are reported in this announcement. Results show broad widths of gold mineralisation at the Firetower prospect including 54.5m at 1.36g/t Au from 0m in 2019FTD001, 29m at 0.78g/t Au from 78m in hole 2019FTD003, 5m at 8.72g/t Au from 81m in hole 2019FTD004, and 23m at 0.53g/t Au from 50m in hole FTD006.

Mineralisation is hosted in a package of volcanic and sedimentary rocks with an apparent structural control. Peak intercept to date is 2m at 21.2g/t Au from 81m in hole 2019FTD004. Results suggest that there is good continuity of mineralisation between sections drilled to date, and highlight potential depth extensions to the known mineralisation. It is apparent that mineralisation is present at, or near to, the bottom of holes 2019FTD001 and 2019FTD006 and as such these holes may be extended in order to test for additional mineralisation at depth. Drill hole collar details and tabulated intercepts are presented in Appendix I and additional drill hole information is presented in Appendix II.

Ground conditions have remained good since programme commencement. Drilling activities are ongoing and are being supported by continuous XRF core scanning. Further analytical results will be reported in the coming weeks.

Notes for Editors:

Greatland Gold plc is a London-listed (LON:GGP) natural resource exploration and development company with a current focus on gold, copper and nickel exploration projects.

The Company has six main projects; four situated in Western Australia and two in Tasmania.  All projects are 100% owned by Greatland.

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 project in the Paterson region of Western Australia. Newcrest has the right to acquire up to a 70% interest in a 12-block area within E45/4701 that covers the Havieron target by spending up to US$65m.

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.

APPENDIX II

JORC Code 2012 Table 1 - Firetower Project

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

Criteria	Explanation
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, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. •    Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. •    Aspects of the determination of mineralisation that are Material to the Public Report. In cases where 'industry standard' work has been done this would be relatively simple (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.	2019 Diamond Drilling ·      Assays have been received for six 2019 Diamond drill holes.  These are the first six holes of a planned 15 hole program. ·      Samples consist of diamond drill core (HQ and NQ sizes) cut in half.  ·      All available core was cut and sampled.  Sampling interval is generally 1m or 0.5m, but respects geological contacts in places.  Sampling was carried out to Greatland internal protocols and QAQC procedures. ·      Entire samples were crushed then pulverised to a nominal 85% passing 75 microns.  The resulting pulps were analysed for Au (50g charge, fire assay) and multi-element geochemistry (four acid digest ICP-MS).  ·      The method of sampling is industry standard for reporting of Exploration Results. ·      Locations and orientation of 2019 drill holes for this release are tabulated in the body of the report.
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).	Diamond Drilling ·      Drilling was undertaken using a track mounted Coretech CSD1800 drill rig.  The drill rig is capable of ~1000m NQ.  ·      Drill holes were cased with HWT casing to ~3m.  HQ sized drill core from 0m to ~20m followed by NQ drill core from 20m to end of hole.
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.	·      Length based core recovery is measured from reassembled core for every drill run.  Data is recorded into laptop computer using 'LogChief' - geological logging software.      ·      Core recovery is very high (97%).  The drilling method employed leads to very high recoveries.  ·      Due to consistently high recoveries, no relationship between grade and recovery is evident.
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.	·      All drill core/samples were geologically logged for lithology, mineralogy, alteration, veining, sulphide occurrences, structure and geotechnical data.  This logging includes both qualitative and quantitative components.  All core is digitally photographed. ·      Logging is recorded directly into a laptop computer using 'LogChief' - geological logging software.  This software has 'look-up tables' that do not allow for invalid entries.  Additional validation is then carried out when data is transferred to Greatlands database managers. ·      All samples are analysed in the field using a pXRF (Olympus Vanta handheld - model VMR) for the purpose of geochemical interpretation. ·      All core is analysed in the field using a Minalyze unit.  This collects ultra-high resolution photography, and continuous XRF measurements.
Sub-sampling techniques and sample preparation	•    If core, whether cut or sawn and whether quarter, half or all core taken. •    If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. •    For all sample types, the nature, quality and appropriateness of the sample preparation technique. •    Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. •    Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. •    Whether sample sizes are appropriate to the grain size of the material being sampled.	·      All sampled core was cut with a core saw in a consistent way that preserved the bottom of hole reference line, where present.  Sampling interval is generally 1m or 0.5m, but respects geological contacts in places. ·      Sample preparation included drying, crushing and pulverising in full to a nominal 85% passing 75 microns.  ·      All staff were adequately trained for all sampling steps, with geologists checking sample sheets prior to loading into the database. ·      The sample sizes are considered appropriate for the style of mineralisation encountered in the region.  ·      No field duplicates have been collected/reported.
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.	·      All samples were submitted for preparation at Intertek laboratory Adelaide.  Pulp samples were then submitted for analysis to Intertek Perth Laboratory. ·      Au analysis - 50g Fire Assay/ICP-OES (detection limit of 0.005ppm). ·      Multi-Element analysis - four acid digestion ICP-MS (for Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Ga, Ge, Hf, In, K, La, Li, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, Re, S, Sb, Sc, Se, Sn, Sr, Ta, Te, Th, Ti, TI, U, V, W, Y, Zn, Zr). ·      No geophysical tools were used for any element concentrations in this report. ·      All samples are analysed in the field using a pXRF (Olympus M-series) for the purpose of geochemical interpretation.  This data is for internal company use only. ·      Quality Control procedures in the field involve the use of certified reference material (CRM's) for assay standards and blanks.  Standards and blanks are inserted every 20 samples.  ·      No field duplicates have been collected/reported.
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.	·      Significant intersections have been verified by multiple company personnel. ·      No twin holes have been drilled. ·      Logging is recorded directly into a laptop computer using 'LogChief' - geological logging software.  This software has 'look-up tables' that do not allow for invalid entries.  Additional validation is then carried out when data is transferred to Greatlands database managers. ·      No adjustments have been made to any assay data. ·      Primary assay data is stored in its electronic form, and retained in both original certificate form (.pdf) and text/.csv files.
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.	Location information ·      Drill hole collar locations were surveyed using a handheld Garmin 64ST GPS (accuracy of ± 5m). ·      All coordinates are in GDA94 Zone55.   ·      Down hole surveys were conducted every 30m using a Pathfinder electronic survey tool (for holes 2019FTD001 à 2019FTD005).  Subsequent holes were surveyed down hole using an Axis Champ Discover survey tool.  ·      Topographic control of drill collars utilises handheld GPS information.
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 planning at Firetower was designed to reduce spacing to ~15m between sections, and drill all holes in the same orientation (north) for the collection of systematic geological information. Average spacing between drill holes on sections is ~40m. ·      Historic drilling was of an ad-hoc nature, with average section spacing (east-west) of ~30m (in the main Firetower area), although holes  have been drilled both to the north and south so continuity of geological information collected has been sparse.   ·      The data spacing is not sufficient to establish a Mineral Resource.
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.	·      It is interpreted that the local geology is sub-vertical.  The orientation of drill holes is not believed to have introduced any bias in sampling.  ·      The orientation of key mineralised structures is unknown.  ·      There is presently insufficient information to confirm the true thickness of any mineralised intervals.
Sample security	•    The measures taken to ensure sample security.	·      Samples were freighted to the Laboratory using Greatland chain of custody protocols.   ·      Verification of sample numbers and identification is conducted by the laboratory on receipt of samples, and sample receipt advise issued to Greatland. ·      Details of all sample movement are digitally recorded.  Dates, Hole ID sample ranges, and the analytical suite requested are recorded with the dispatch of samples to analytical services.
Audits or reviews	•    The results of any audits or reviews of sampling techniques and data.	·      No audits have been completed. ·      No reviews are considered required due as the project is in early phase of exploration.

Section 2 Reporting of Exploration Results

(Criteria listed in the preceding section also apply to this section.)

Criteria	Explanation
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 Firetower Project is located wholly within the following Exploration Licence: ·      EL26/2004 (granted) ·      Greatland Pty Ltd holds a 100% interest in EL26/2004 ·      The tenements are in 'good standing' with Minerals Resources Tasmania (MRT). ·      No known impediments exist, including a licence to operate in the area.
Exploration done by other parties	•    Acknowledgment and appraisal of exploration by other parties.	·      Exploration in the region of the Firetower Project has involved the following companies: ·      Arasco (1970's) ·      CRA (1984) ·      Noranda and Noranda Plutonic JV (1989-1993) ·      Sirrocco (2000) ·      Auriongold (2001-2002) ·      Greatland Pty Ltd (2004-2011) ·      Unity Mining Limited (2011-2014) ·      Greatland Pty Ltd (2015 - current)
Geology	•    Deposit type, geological setting and style of mineralisation.	·      The Firetower project lies in the central north of Tasmania within equivalents of the Mt Read Volcanics. ·      Gold mineralisation is hosted in volcanoclastic rocks and manifests as sheeted veins (and breccias) with associated pyrite, haematite, quartz and limonite.
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.	·      A tabulation of the collar details and significant intersections is within the body of the release. ·      Reports prepared by Greatland Pty Ltd are available to view on: www.greatlandgold.com
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.	•    Exploration results are reported by length weighted average.  •    Significant intersections are reported as minimum length of 1m - greater than or equal to 0.2ppm Au with up to 4m of internal dilution and intervals greater than or equal to 0.5ppm Au with zero metres of internal dilution.
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').	•    Down hole lengths are reported, 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.	•    Appropriate diagrams are available with this report.
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 company believes this announcement is a balanced report, and that all material information has been reported.
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.	•    Previous exploration results included in this announcement can be found on the company website: www.greatlandgold.com
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 results are awaited for the remaining  holes.  •    Planned further work includes geological and geochemical investigation of drill results with the aim of developing a 3D geological model of the project.
