Warrentinna Drilling Intersects High-Grade Gold
Mineralisation
Targeted, low-cost diamond drilling programme at Derby North
prospect returns high-grade gold intercepts, including 21.7m @
3.3g/t Au from 9.3m
Greatland Gold plc (AIM: GGP), the precious and base metals
exploration and development company, is pleased to announce that it
has intersected high-grade gold mineralisation from its maiden
diamond drilling programme at Derby North, a prospect within the
Company's 100% owned Warrentinna project in Tasmania,
Australia.
Greatland previously conducted limited Reverse Circulation
("RC") drilling at Derby North, which outlined a gold mineralised
system approximately 150m long and 100m wide, open to the north,
east and at depth. The Company has now completed its maiden diamond
drilling programme at the prospect with three diamond holes for a
total of 285m of drilling. This targeted drilling campaign was
designed to provide a better understanding of the host rocks, type
and tenor of gold mineralisation, and highlight any structural
controls. Laboratory assay results have now been received and are
announced today.
Highlights of Drill Results
-- Maiden diamond drill programme at Derby North prospect
intersects high-grade gold mineralisation and increases depth
extent of known mineralisation.
-- Best results include:
o 21.7m @ 3.3g/t Au from 9.3m (2019WTD001), including
-- 2.2m @ 12g/t Au from 10.8m
o 11.7m @ 2.8g/t Au from 115m (2019WTD002) - a new zone of gold
mineralisation beneath previous drilling
o 43m @ 1.5g/t Au from 10m (2019WTD003)
-- Results and data collected from the drilling programme are
expected to assist with potential divestment of the project, in
line with the Company's strategy to seek to divest non-core
projects.
Gervaise Heddle, Chief Executive Officer, commented: "These
positive results from our maiden diamond drilling campaign at
Warrentinna further increase the depth extent of the known
mineralised zone and clearly demonstrate the potential for a
significant gold mineralised system at Derby North.
"The drill core and associated data collected has greatly
improved the Company's understanding of the mineralised system and
should assist with any potential divestment of the project. Our
immediate next step is to complete an evaluation of the results to
assess the project's potential, referencing Orogenic-type gold
occurrences in central Victoria which include the Fosterville and
Bendigo gold deposits."

Reporting Criteria: Intercepts reported as a minimum length of

dilution of 4m and intervals greater than or equal to 1ppm Au with
zero metres of internal dilution. Au is reported to two significant
figures.
Overview of the Warrentinna Project, Tasmania
The Warrentinna project is located in north-east Tasmania and
covers an area of approximately 37 square kilometres of Mathinna
Group rocks which comprise metamorphosed sandstones, siltstones and
mudstones of Ordovician to Silurian age. The Mathinna Group
metasediments, together with intrusive Devonian granites, cover
much of the north-eastern parts of Tasmania and are considered
equivalent to rocks of the Melbourne Trough which host the bulk of
Victoria's Orogenic-type gold mineralisation. Examples of these
types of deposits are Fosterville and Bendigo. Greatland is
targeting this style gold mineralisation.
Diamond Drilling at Derby North Prospect
Greatland completed three diamond core holes for a total of 285m
at the Derby North prospect within the Warrentinna project.
Greatland previously conducted shallow RC drilling at the prospect,
but this is the first time the Company has undertaken a diamond
drilling programme. The diamond holes 'twinned' two historic RC
drill holes that had intersected significant high-grade gold
mineralisation (see announcement dated 11 November 2019). The
diamond holes were completed to gain a better understanding of the
host rocks, type and tenor of gold mineralisation, and highlight
any structural controls.
The drill programme successfully achieved its aims by confirming
the presence of significant widths and grades of gold
mineralisation previously seen in RC drilling. Drill Hole
2019WTD001 intersected the targeted shallow mineralised zone
returning 21.7m at 3.3g/t Au from 9.3m, including high grade zones
such as 2.2m at 12g/t Au from 10.8m and peak intercept grade for
the drill programme of 0.5m at 15g/t Au from 17m. This hole did not
reach target depth due to hole conditions. 2019WTD003 was a step
back hole that drilled under 2019WTD001 and intersected a very
broad near-surface zone of gold mineralisation returning 43m at
1.5g/t Au including a higher grade zone of 2.5m at 5.1g/t Au from
31.8m. Drill hole 2019WTD002 was collared approximately 25m to the
south of 2019WTD001, and intersected the two targeted deeper
mineralised zones returning 12.65m at 1.5g/t Au from 79m and 10m at
2.0g/t Au from 98m, respectively. Significantly, the bottom of hole
2019WTD002 intersected a new zone of gold mineralisation, beneath
previous drilling, returning 11.7m at 2.8g/t from 115m including
higher grade zones of 4m at 4.7g/t Au with a peak intercept grade
of 0.5m at 10g/t Au from 122m.
The drill core and associated data collected has greatly
improved the Company's understanding of the mineralised system,
including rock type identification, lithological variations, and
potential structural controls. Mineralised zones present as quartz
stock working and veins in fine grained siltstone rocks. The
results reported today have further increased the depth extent of
the known mineralised zone and clearly demonstrate the potential
for a significant gold mineralised system at Derby North which
warrants further exploration efforts. An evaluation of results will
be completed to assess the project's potential, referencing
Orogenic-type gold occurrences in central Victoria which include
the Fosterville and Bendigo gold deposits. Results and data
collected from the maiden diamond drilling programme are expected
to assist with potential divestment of the project.
Additional drill hole information and tabulated drill hole
intercepts are presented in Appendix I and Appendix II.

Notes for Editors:
Greatland Gold plc is a London Stock Exchange AIM-listed
(AIM: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 earn up to a 70% interest in a
12-block area within E45/4701 that covers the Havieron target by
spending up to US$65 million.
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.
