NEWS RELEASE | 30 November 2023
Nickel prospectivity confirmed in soil sampling at Panorama
800 metre coherent nickel strike defined in favourable
geology
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 the Company) is
pleased to announce the results of surface sampling across its
Panorama East, Panorama and Panorama North tenure. The Panorama
project is located approximately 200km south east of Port Hedland
in the Pilbara region of Western Australia, and is considered
prospective for Archean gold and nickel. The combined soil and rock
chip sampling program was designed to follow up along strike of
previous surface sample results and to test conductors identified
in an airborne electromagnetic survey.
Highlights
-- Surface sampling program was undertaken with results
including 27 soil samples from the Ni_04 prospect returning above
0.1% nickel over a 1.4km strike extent, and a peak result of 0.3%
nickel in a rock chip sample.
-- Nickel strike includes 800 metre coherent +0.18% nickel
anomaly.
-- These nickel results sit within the Dalton Suite ultramafics,
which is confirmed as nickel enriched and a potential primary
nickel sulphide host.
-- Several untested highly prospective conductors sit within the
14km of unsampled Dalton Suite.
Greatland Managing Director, Shaun Day, commented:
"Our recent surface sampling at Panorama has delivered a
strongly positive result for nickel prospectivity.
The large extent of the prospective Dalton Suite ultramafics
within our tenure, and the existence of coincident untested
conductors, gives us confidence in the potential for a substantial
nickel discovery at Panorama.
We are now planning our next steps to effectively test both the
geochemical and geophysical anomalies on the tenure."
Overview of the Panorama project
Greatland's Panorama project comprises three tenements (157
km(2) ) located approximately 200km south east of Port Hedland in
the Pilbara Craton of Western Australia. (Figure 1).

========== =============== ============== ===========
The geology of the area is predominantly greenstone and granite
of the Archean Pilbara Craton in northern Western Australia. Coarse
grained Archean volcano-sedimentary rocks ("greenstones") strike
over 7km from north to south throughout the Panorama project area.
The greenstones form the "Coongan Syncline" and lie between the
Shaw batholith to the west and the Coongan batholith to the north
east.
Importantly the sequence is intruded by ultramafic rocks of the
Dalton Suite (illustrated in purple in Figure 2). These units are
considered prospective for primary nickel sulphide deposits.

Previous work
Limited soil sampling (489 samples) completed by Greatland over
the tenure previously in 2019 identified the Dalton Suite as
anomalous for nickel.
A detailed aeromagnetic survey assisted in mapping out the
extents of the Dalton Suite and a follow up airborne
electromagnetic survey highlighted 28 conductors, 12 of which are
located within the Dalton Suite and may correlate to massive
sulphides.
No drilling has been undertaken across the tenements.
Surface Sampling Program
Eight soil grids (refer Table 2 and Figure 2) were designed so
that a sample was taken every 50m on lines generally 200m apart at
each prospect to test predominantly the nickel and gold
prospectivity across the tenure, with a focus on conductors within
the Dalton Suite.
A total of 832 soil samples were taken.
Opportunistic rock chips were taken where favourable outcrop was
identified. In total, 74 rock chips were taken with an estimated
weight of 2kg each.
All samples were sent to Intertek laboratory in Perth for
multi-element analysis.

Assay Results
Results returned for the recent program displayed a peak of 0.3%
nickel in a rock chip from the Ni_04 prospect within the Dalton
Suite (Figure 3). The Ni_04 prospect returned a total of 27 soil
samples above 0.1% nickel over a 1.4km strike, within which a
coherent core nickel anomaly of 800m strike at > 0.18% nickel
was outlined.
A further four soil samples in the Ni_02 prospect reported above
0.1% nickel.
Three surface samples returned gold results above 100ppb, all
within the Ni_03 prospect. The peak assay was 142ppb gold. No
coherent anomaly was detected.
Discussion
The nickel anomaly identified on the NI_04 prospect strongly
increases the prospectivity of the Dalton Suite ultramafics within
the tenure.
Primary nickel sulphide deposits such as Radio Hill (Figure 1)
located 50km south of Karratha within the Pilbara craton and 350km
west of Panorama, are formed during the emplacement of the host
mantle derived ultramafic rocks into the crust. The (nickel)
sulphides accumulate in structural depressions along the basal
contact and in feeder conduits (Hoatson et al. 2006) as they are
insoluble in the melt and have high density. These accumulations
can be identified as short strike length conductors with
electromagnetic surveys.
These latest results confirm the Dalton Suite in the Company's
tenure as nickeliferous. The untested, folded 14km strike extent of
the Dalton Suite within the tenure includes five untested
conductors identified from the airborne electromagnetic (EM) survey
in addition to the 800m Ni_04 geochemical anomaly. The short strike
length conductors A13 and A17 identified from the airborne EM
(Figure 4) in untested Ni_01 prospect may represent base of channel
sulphide accumulations in the Dalton Suite. Similar to the Radio
Hill deposit (M. De Angelis 1987), these anomalies also have
coincident magnetic anomalies.
Planning is underway to determine the follow up on the highly
favourable geochemical and geophysical anomalies within the Dalton
Suite.

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 Newcrest'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.
