Dissemination of a Regulatory Announcement that contains inside

Greatland Gold plc
("Greatland" or "the Company")
Panorama Project - Exploration Update
Results of soil sampling confirm the presence of gold anomalism
along the main mineralised trend at Greatland's Panorama
project
Greatland Gold plc (AIM:GGP), the precious and base metals
exploration and development company, is pleased to announce a
surface geochemical programme has confirmed the presence of gold
anomalism along the main mineralised trend at the Company's 100%
owned Panorama project, located in the Pilbara region of Western
Australia.
Greatland completed a systematic, grid based, surface
geochemical soil sampling programme at Panorama during July and
August 2019 which involved the collection of 468 samples at a
density of 200m x 50m and 100m x 50m over approximately 4.5km of
strike. Results from the geochemical sampling are presented in this
announcement.
Highlights:
-- Results of soil sampling confirm the presence of gold
anomalism along the main mineralised trend previously identified by
rock chips and coarse gold (nuggets).
-- Multiple discrete gold in soil anomalies identified,
including a 600m by 200m area which returned results in excess of
50ppb gold.
-- Four samples returned gold values in excess of 100ppb with
one sample exceeding upper detection limit from the laboratory
(>2000ppb).
-- Further work planned to determine the limits of gold
anomalism at surface and the relationship between the gold in soil
anomalism and bedrock mineralisation.
In addition, the Company is pleased to provide images from a
detailed airborne magnetic survey conducted at Panorama earlier
this year which can be found on the Company web site at
www.greatlandgold.com.
Gervaise Heddle, Chief Executive Officer, commented: "We are
very encouraged by the results from our soil sampling campaign at
Panorama which highlight several areas of gold anomalism along the
mineralised trend. These geochemical results, combined with images
from the recent detailed aeromagnetic survey, enhance our
understanding of the project and build upon the work we conducted
earlier this year which identified gold in rock chips and coarse
gold over six kilometres of strike.
"While exploration at Panorama is still in the very early
stages, we are pleased by the progress made this year and look
forward to providing shareholders with details of further work as
we seek to advance this exciting gold prospect."

Panorama Project
The Panorama project consists of three adjoining granted
exploration licences located in the Pilbara region of northern
Western Australia. The three licences cover a total area of
approximately 155 square kilometres and are prospective for gold
and base metal mineralisation.
Geology of the area is predominantly greenstone and granite of
the Archean Pilbara Craton in northern Western Australia, and
younger overlying sedimentary and volcanic sequences.
The Company completed a detailed review of historical data which
revealed several rock chip samples with an elevated gold response
from within the project area. These lie along a generally
north-south trending zone with results including 66.0g/t, 14.5g/t,
4.1g/t, 2.1g/t. The geological setting is a prominent ridge marking
the structural contact of basaltic and ultramafic rocks of Archean
age.
Greatland has carried out sporadic rock chip sampling within
this zone during confirming the presence of bedrock mineralisation
returning results including 18.45g/t and 1.82g/t, 0.71g/t, and
0.61g/t gold. Subsequent prospecting activities by Greatland
located coarse gold (nuggets) in small creeks, and in the soil
profile overlying basaltic bedrock. The gold in rock chip samples
and presence of coarse gold has been identified over a strike
length of approximately 6.1 km.
A systematic, grid based, surface geochemical soil sampling
programme was completed during July and August 2019 which involved
the collection of 468 samples at a density of 200m x 50m and 100m x
50m over approximately 4.5km of strike. Results from the
geochemical sampling have been received and are presented in this
announcement.
Results of soil sampling confirm the presence of gold anomalism
along the main mineralised trend identified by rock chips and
coarse gold (nuggets). Significantly, multiple discrete gold in
soil anomalies are present, including the delineation of a 600m x
200m area of +50ppb gold. Four samples returned gold values of
+100ppb with one sample exceeding upper detection limit from the
laboratory (>2000ppb). It is apparent that gold geochemical
anomalism is open on several lines and additional soil sampling
should be carried out. Overall, the Company is pleased with the
results of the soil sample programme, but further work is required
to determine the relationship between the soil geochemical
anomalism and bedrock mineralisation and coarse gold (i.e. gold
found in rock chips or as nuggets).
A detailed, low-level, high-resolution airborne magnetic,
radiometric and elevation geophysical survey was collected over the
entire Panorama project. The survey comprised approximately 8,092
line kilometres flown at a traverse line spacing of 50m with a mean
terrain clearance of 30m. Previous aeromagnetic coverage of the
area included 200m and 400m line spaced surveys. The new 50m line
spaced aeromagnetic survey by Greatland is complete and final data
received. The data provides significantly increased resolution of
basement features and details of local structural architecture.
The combination of gold in rock chips and as coarse gold, new
geochemical data and recent detailed aeromagnetic survey provides a
comprehensive data set the Company will use to assist in geological
and structural interpretation of basement geology and targeting.
Further work is likely to comprise geological mapping and
additional soil sampling, along with local scale geophysical
surveys if warranted.

Notes for Editors:
Greatland Gold plc is 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.
