NEWS RELEASE | 14 November 2023
Drilling commences at 100% owned Ernest Giles Project
Co-funded diamond core drilling to test the high priority Meadows gold
prospect
Greatland Gold plc (AIM:GGP) (Greatland or the Company) is pleased to advise
that drilling has commenced at the Meadows gold prospect within the Ernest
Giles Project (Ernest Giles).
Highlights
§ Ernest Giles is an underexplored Archean greenstone belt which lies within
the highly mineralised Yilgarn Craton of Western Australia
§ A drill rig is on site and has commenced diamond core drilling at the
highly prospective Meadows gold prospect
§ Heritage surveys and mobilisation was completed safely and quickly
following entry into the Ernest Giles Land Access Agreement (LAA) in September
2023
§ First two diamond holes will test interpreted mineralised zones and are
co-funded by the Government of Western Australia's Exploration Incentive
Scheme (EIS) drilling grant for up to A$220,000 (£115,000)
§ Current drilling builds on previous work at Ernest Giles and will provide
important geological and structural information to inform a systematic reverse
circulation drill program in 2024
Greatland Managing Director, Shaun Day, commented:
"We are very pleased to be drilling the high priority Meadows gold prospect at
Ernest Giles following conclusion of the Land Access Agreement."
"Ernest Giles sits within an underexplored greenstone belt located north of
the world-class Tropicana and Gruyere gold operations. As a 100% owned
project, Ernest Giles represents an excellent exploration opportunity for
Greatland and our shareholders."
Overview of the Ernest Giles Project
The Ernest Giles Project is located approximately 250km north-east of the town
of Laverton and covers a folded belt of magnetic greenstone rocks (Figure 1)
which is typical of the highly gold and nickel endowed parts of the Archean
Goldfields of Western Australia. The Goldfields host large gold camps such as
Kalgoorlie, St Ives, Leonora, Laverton, Mt Magnet, Jundee, Gruyere and
Tropicana. The prospective greenstone sequence at Ernest Giles does not
outcrop and is therefore underexplored relative to the remainder of the
Goldfields.
Greatland's granted and under-application tenure at Ernest Giles comprises a
comprehensive holding over what Greatland considers to be the most prospective
near surface portions of the Ernest Giles belt, covering more than 1,950km(2).

Current drilling program
Previous exploration at Ernest Giles included a program of 62,800m spaced
vertical RC drillholes, largely focused on the Meadows prospect, in addition
to airborne magnetics and ground gravity surveys.
Gold mineralisation and anomalism is hosted within altered mafic volcanic,
banded iron formation (BIF) and syenite. The mafic is pyrite and albite
altered with thin quartz veinlets. Hematite alteration has also been observed.
The syenite comprises disseminated pyrite and may be hematite altered.
Results returned previously included a peak of 16m @ 0.36g/t Au from 182m
downhole including 3m @ 1.28g/t Au in hole ERC011. Table 1 in Appendix 1 sets
out all significant results.
The two EIS co-funded diamond core drill holes will provide the first angled
diamond holes and oriented core at Meadows, considered critical for the
geological understanding of the project.
Drill hole EG_Prop_1 targets two mineralised zones within the previous
vertical RC hole ERC011 which returned values +1g/t Au (Appendix 1, Table 1)
in mafic rock (Figure 4).
Drill hole EG_Prop_2 targets the interpreted syenite (intrusive granitoid)
body intersected in ERC014 which returned 18m @ 0.11g/t Au (Appendix 1, Table
1).
In addition, the drilling is planned to:
§ confirm gold mineralisation and anomalism intersected in previous RC
drilling and test for continuity down dip;
§ provide geological and structural information to understand the setting and
nature of gold mineralisation;
§ investigate a larger section across strike than has been possible with
vertical drillholes;
§ identify pathfinders for mineralisation; and
§ be utilised as a platform for downhole geophysics should it be viable.

Further work
Additional ongoing work will include airborne geophysics to better understand
the geology of the entire Ernest Giles belt. A follow up RC drilling program
will be designed utilising the knowledge gained from the current drilling, to
systematically target the best results of all drilling at Meadows to date.
This work will commence in the 2024 calendar year.

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 world gold major, Newmont
Corporation.
Havieron is located approximately 45km east of Newmont's existing Telfer gold
mine. The box cut and decline to the Havieron orebody commenced in February
2021. Total development now exceeds 2,820m including over 2,030m of advance in
the main access decline (as at 8 October 2023). Subject to a positive
feasibility study and Decision to Mine, Havieron is intended to leverage the
existing Telfer infrastructure and processing plant. Access to Telfer will
de-risk the development and reduces capital expenditure.
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.

§ Documentation of primary data, data entry procedures, data verification,
data storage (physical and electronic) protocols § There are no adjustments to assay data, other than below detection samples
are reported at negative one half the detection limit.
§ Discuss any adjustment to assay data.
MMI Results correlated favourably with pre-existing drilling and with a trial
of Newcrest's proprietary Deep Sensing Geochemistry (DSG) sampling.
Location of data points § Accuracy and quality of surveys used to locate drill holes (collar and § Drill collar and surface sample locations were surveyed using hand held
down-hole surveys), trenches, mine workings and other locations used in GPS. RL's were collected with the same GPS
Mineral Resource estimation.
§ As all holes were drilled vertically drill rig alignment was not required.
§ Specification of the grid system used.
§ Downhole survey was collected using a single shot reflex down hole camera
§ Quality and adequacy of topographic control for diamond holes at 90 metres, then base of transported and every fifty
metres in bedrock. No downhole surveys were taken for RC holes
§ The topography is generally low relief to flat, elevation within the dune
corridors in ranges between 250-265m AHD steepening to the southeast
§ All coordinates are provided in the Geocentric Datum of Australian (GDA94
Zone 51). All relative depth information is reported in Australian Height

Data spacing and distribution § Data spacing for reporting of Exploration Results RC holes were vertical and drilled on a broad grid spacing of 1,600m x 800m.
The broad spaced holes were designed to test basement lithologies for gold
§ Whether the data spacing and distribution is sufficient to establish the mineralisation which had been intersected in previous 'wildcat' drilling by
degree of geological and grade continuity appropriate for the Mineral Resource the company, and also test geochemical responses from surface sampling work
and Ore Reserve estimation procedure(s) and classifications applied carried out by a previous explorer.
§ Whether sample compositing has been applied § RC samples including RC pre-collars were original composited to 4m. any
anomalous intervals where then re-assayed on 1m intervals.
Diamond drilling was carried out on a "wild cat " basis with individual holes
testing geochemical and geophysical anomalies
The drill data spacing is not sufficient for calculation of a mineral resource
or reserve and none is reported.
MMI sampling was done on 200m x800m basis with the shorter distance across
strike.
Orientation of data in relation to geological structure § Whether the orientation of sampling achieves unbiased sampling of possible § Drilling is vertical into what are expected to be dominantly vertical
structures and the extent to which this is known, considering the deposit type stratigraphy. Any mineralisation intervals are expected to be significantly
greater than true width.

Exploration done by other parties Acknowledgment and appraisal of exploration by other parties CRA initially carried out an aeromagnetic survey in the mid 90's.
WMC after reviewing the geophysics interpreted the area as containing
archean greenstones, and completed regional soils and gravity surveys along
with 200m spaced aeromagnetic and 8 RC holes (ENGC01-8) over what is now the
Meadows prospect, identifying anomalous gold between 1996 and 1999.
MRG metal completed further aeromagnetics and 3 diamond holes
(EY4001-EY4003) in the region from 2011 to 2015.
Geology Deposit type, geological setting and style of mineralisation Exploration is for Yilgarn style Archean lode gold.
Drill hole Information A summary of all information material to the understanding of the exploration Drill hole collar details are listed in Appendix 1 (Table 2) and anomalous
results including a tabulation of the following information for all Material results in Appendix 1 (Table 1).
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
Data aggregation methods In reporting Exploration Results, weighting averaging techniques, maximum No economically significant results have been reported, and no data

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')

include, but not be limited to a plan view of drill hole collar locations and
appropriate sectional views
Balanced reporting Where comprehensive reporting of all Exploration Results is not practicable, The reporting is considered balanced.
representative reporting of both low and high grades and/or widths should be
practiced to avoid misleading reporting of Exploration Results
Other substantive exploration data Other exploration data, if meaningful and material, should be reported No other substantive exploration data other than that provided in the figures.
