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.

Relationship
between * These relationships are particularly important in the * No economically significant results are reported, and
mineralisation reporting of Exploration Results there is no known relationship between reported
widths widths and the geometry of any mineralisation
and intercept
lengths * If the geometry of the mineralisation with respect to
the drill hole angle is known, its nature should be * All intercepts are reported downhole as true width is
reported not known
* 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')
------------------------------------------------------------ ------------------------------------------------------------
Diagrams
* Appropriate maps and sections (with scales) and * Maps are provided in Figures 1-2. No significant
tabulations of intercepts should be included for any discovery is reported
significant discovery being reported These should
include, but not be limited to a plan view of drill

------------------------------------------------------------ ------------------------------------------------------------
Balanced
reporting * Where comprehensive reporting of all Exploration * The reporting is considered balanced
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
------------------------------------------------------------ ------------------------------------------------------------
Other
substantive * Other exploration data, if meaningful and material, * No other substantive exploration data other than that
exploration should be reported including (but not limited to): provided in the figures
data 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
