Dissemination of a Regulatory Announcement that contains inside information according to REGULATION (EU) No 596/2014 (MAR).

("Greatland" or "the Company")
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."

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.
