Gervaise Heddle, Chief Executive Officer, commented: “These exciting drill results at Black Hills confirm the presence of a near-surface gold system at the Saddle Reefs prospect which includes high-grade gold mineralisation.
In addition, our systematic exploration approach continues to generate new targets across the region, including three within the Black Hills area which have not been tested by historic drilling.
“The results from our drilling and geophysical work at Black Hills further highlight the exceptional prospectivity of the Paterson region, which continues to draw in major resource players to the underexplored province.”
In June 2018, Greatland commenced its first exploration campaign at Black Hills. Surface rock chip sampling located outcropping gold mineralisation over several hundred metres at the Saddle Reefs prospect and subsequent geophysical work outlined a large, coherent chargeability anomaly over 1,400m of strike, subparallel to gold mineralisation identified at surface. Recent drilling completed at Black Hills has partially tested the Saddle Reefs prospect and has confirmed the presence of high-grade gold.

Black Hills – Positive Final Drill Results & New Geophysical Targets
Drill results confirm the presence of high-grade gold mineralisation at the Black Hills’ Saddle Reefs prospect, including 1m @ 10.96g/t gold from 35m (SRRC011)
Ground gravity surveys identify three new geophysical targets at Black Hills
Greatland Gold plc (AIM:GGP), the precious and base metals exploration and development company, is pleased to announce positive final drill results with several intervals greater than 5g/t gold at its 100% owned Black Hills project in the Paterson region of Western Australia. The Company is also pleased to report it has identified three new geophysical targets following the completion of ground gravity surveys over the Black Hills licence and adjacent Havieron licence.
AÂ Reverse Circulation (“RC”) programme has been completed at Black Hills with a total of twenty RC holes for 5,846m, drilled to depths ranging from 154m to 500m. All holes were sampled from surface to end of hole as four metre composites with single metre samples analysed in areas of gold anomalism. Final analytical results have been received for all samples and are reported in this announcement.
Highlights of Drill Results
·    Results received confirm the presence of high-grade gold mineralisation at the Saddle Reefs prospect. Best results include:
o  13m @ 2.01g/t Au from 67m (SRRC012), including
§ 2m @ 7.38g/t Au from 77m
o  12m @ 1.38g/t Au from 32m (SRRC011), including
§ 1m @ 10.96g/t Au from 35m
o  36m @ 0.35g/t Au from surface (0m) (SRRC010)
o  19m @ 0.51g/t Au from 118m (SRRC007)
·    New drill results are considered very positive with several intervals greater than 5g/t gold, indicating the potential for a fertile gold system at Black Hills.
New Targets at Black Hills
·    Greatland has completed ground gravity surveys over the entire Black Hills licence and adjacent Havieron licence, which have identified three new geophysical targets in the Black Hills area:
o  Parlay – Located in the south-western corner of the Black Hills licence, the Parlay target includes magnetic and gravity anomalies on an interpreted key lithological and structural contact.
o  Black Hills North – Located to the north of recent drilling, Black Hills North comprises coincident gravity, magnetic and IP anomalies.
o  Black Hills South – Located on Greatland’s Havieron licence (E45/4701), Black Hills South is a very high amplitude gravity anomaly located at the interpreted closure of the Black Hills Dome to the south of outcrop under relatively thin cover (approximately 50m).
Overview of Paterson Project and Black Hills licence
The Company’s Paterson project comprises the Havieron, Paterson Range East, and Black Hills licences, located in the Paterson region of northern Western Australia. The three licences collectively cover more than 385 square kilometres and are prospective for Havieron and Telfer style gold-copper mineralisation.
The Paterson region is currently one of the most active exploration areas in Australia. Recent exploration success achieved by Greatland Gold and Rio Tinto demonstrates the region has been underexplored, particularly the extensive areas under cover. As well as hosting several large gold and copper deposits such as Telfer and Nifty, more recent exploration has outlined several other deposits including Magnum (Au), Calibre (Au), O’Callaghans (W, Cu) and Maroochydore (Cu). The region is remote, however infrastructure is good with several operating mines, roads, formed tracks and rail networks nearby which branch out from the regional industrial hub of Port Hedland 500km to the west.
The Black Hills licence, E45/4512, lies 30 km east of the large Telfer gold mine. Black Hills is a granted exploration licence that covers 25 square kilometres and sits adjacent to the Company’s Havieron exploration licence. The Black Hills licence is regarded as having high potential to host gold mineralisation, similar in style to that seen at Telfer. There has been a considerable amount of historical exploration work at Black Hills with several discrete zones of mineralisation identified over 5km of strike. Historical rock chip samples have returned gold over 10g/t, with free (visible) gold in places. Historic drill intercepts include 3m at 9.14g/t gold from 26m downhole (incl. 1m at 21.2g/t from 27m (CBR073)), 1m at 10.0g/t gold from 16m (CBH138), 1m at 4.93g/t from 12m (CBH071) and 1m at 3.12g/t from 37m (NBH004).
Gold prospects identified to date extend from Black Hills into the north western parts of the Havieron licence. Proterozoic sandstone and carbonate rocks of the Yeneena Group formations are present, including the Telfer Formation, in a domal structure which is the equivalent geology to that of the large Telfer gold deposit located 30km to the west.
A large amount of historical surface exploration data for the Black Hills area has been compiled and incorporated into the Company’s database. Gold mineralisation has been outlined at several prospects throughout the licence including Saddle Reefs, Eastern, Rogers and Northern Granites (within an area of 6.5km x 2km).
The Company commenced field activities at Black Hills in mid-2018. Work focused on the Saddle Reefs and Rogers areas, collecting rock chip samples and locating historical access. The host sequence of Proterozoic sandstones and limestones outcrop through relatively thin sand cover. Numerous indications of mineralisation in bedrock are apparent. Gossanous samples were collected from outcrop, visible gold recovered from rock chip samples, and gold nuggets were found in thin sand cover at Saddle Reefs.
At Saddle Reefs, the mineralised sequence outcrops through a thin veneer of sand and gravel. Rock chip samples were collected over a strike length of approximately 800m with results over 10g/t gold including 81.7g/t, 45.7g/t, 37.6g/t, 33.9g/t, 28.2g/t and 23.5g/t. Many also showed high silver above 10g/t up to a maximum of 106.1g/t. Gold (and silver) mineralisation in bedrock has been identified over a strike length of approximately 800m at Saddle Reefs.
Comprehensive Induced Polarisation (“IP”) geophysical work over Saddle Reefs was undertaken during mid 2018 and early 2019 which covered a strike length of 2km. Modern 3D inversion models of resultant IP data were generated. These models outlined a large chargeability anomaly over 1,400m of strike subparallel to gold mineralisation identified at surface.
As previously reported, an RC drill program has been completed at Black Hills with 1m results reported in this announcement. RC drilling largely focussed on the Saddle Reefs prospect, with several additional holes into the Saddle Reefs West and Eastern prospects. A total of twenty RC holes for 5,846m were drilled to depths ranging from 154m to 500m. Holes were primarily angled at 60 degrees. All holes were sampled from surface to end of hole as four metre composites and single metre samples, and analysed for a 49 element suite. Single metre samples were analysed where 4m composites returned gold results of 0.1g/t or greater. Final analytical results have been received for the 20 holes completed. The first 13 holes represent three traverses of drill holes across portions of the Saddle Reefs prospect with highest results of 1m @ 10.96g/t gold from 35m (SRRC011) and 2m @ 7.38g/t Au from 77m (SRRC012). Results received confirm the presence of high-grade gold mineralisation at the Saddle Reefs prospect. Significant intercepts are presented in Table 1.
