Latest results further highlight the potential for extensions to the Initial Resource
Early Works advancing with box cut and surface works nearing completion
Greatland Gold plc (AIM:GGP), the precious and base metals exploration and development company, is pleased to provide an update on the drilling campaign at the Havieron deposit in the Paterson region of Western Australia. The Company notes the release of an ASX announcement titled “Quarterly Exploration Report” by Newcrest Mining Ltd (“Newcrest”) earlier today.
Drilling activities since the last report include new results from the Growth Drilling programme, which continue to support the potential for resource expansion of the Havieron system. Infill drilling from within the Inferred Mineral Resource Boundary (at a nominal 50m by 50m spacing) is designed to support the delivery of an Indicated Mineral Resource estimate in the South East Crescent Zone and adjacent Breccia Zone. It should be noted that the results for infill drilling were received in the March 2021 quarter, and reported in the Greatland release ” Further Outstanding Infill Drilling Results at Havieron”, dated 11 March 2021.
Assay results for four new drill holes from the Growth Drilling programme (not previously reported) have been received and are reported here today, with all holes intersecting significant mineralisation.
Results from the 26 holes from the infill drilling programme reported in the last update (” Further Outstanding Infill Drilling Results at Havieron”, dated 11 March 2021) are included below.
Highlights
§ Excellent Results from Growth Drilling:
o Results from Growth Drilling continue to support the potential for resource expansion of the Havieron gold-copper mineralised system, particularly within and around the Northern Breccia, and below the Inferred Mineral Resource estimate in the South East Crescent Zone and adjacent Breccia Zones.
§ Excellent Results from Infill Drilling (previously reported 11 March 2021):
o The high-grade infill drilling results provide additional confidence of both geological and grade continuity within the existing resource shell .
o This supports the delivery of an Indicated Mineral Resource estimate in the South East Crescent Zone and adjacent Breccia Zones.
§ 2021 Growth Drilling Programme: The 2021 Growth Drilling programme is ongoing, with priorities established:
o North West Crescent and Northern Breccia: The Growth Drilling programme will initially focus on the North West Crescent and Northern Breccia zone and is aimed at providing support for the potential expansion of the existing Inferred Mineral Resource.
o Eastern Breccia: Drill testing and interpretation of the geological and mineralisation controls of the Eastern Breccia Zone is ongoing.
o South East Crescent and Breccia: Targeting potential resource definition of extensions below the existing resource shell and lateral extensions adjacent to the existing high-grade resource shell .
o New Targets: New targets outside of the immediate vicinity of the Havieron deposit, but within the Havieron Joint Venture area, have been identified with the potential to conduct drill testing of these targets in the future.
§ Early Works Underway: As announced on 21 January 2021, earthmoving activities for construction of the box cut and decline have commenced.
o Excavation of the box cut commenced on 8 February 2021. Box Cut is 90% complete and surface works are 85% complete.
o Portal establishment is expected in the coming weeks.
o Newcrest is progressing the necessary approvals and permits required to commence the development of an operating underground mine.
o Work continues to investigate the potential to achieve commercial production at Havieron within three years of the commencement of the decline.

Shaun Day, Chief Executive Officer of Greatland Gold plc, commented: “We are very pleased with another set of excellent results which continue to highlight the world-class potential of Havieron. The latest results from the Infill and Growth Drilling campaigns further support the delivery of an Indicated Mineral Resource as well as the potential expansion of the Havieron gold-copper mineralised system.
“Alongside this, the joint venture continues to advance earthmoving activities with the box cut and surface works nearing completion and the portal and decline progressing to plan. With the 2021 65,000m drilling campaign well underway and the early works programme progressing at pace, we look forward to updating the market on the continuing progress at Havieron.”
Analytical results for new drilling from HAD083BW4, HAD86, HAD090 and HAD106W1 have been received and are announced today, along with results from HAD060W3, HAD112, HAD113W2, HAD114W1, HAD114W2, HAD115, HAD116, HAD116W1, HAD117, HAD117W1, HAD118, HAD119, HAD119W1, HAD120, HAD121, HAD122, HAD123, HAD124, HAD125, HAD126, HAD127, HAD128, HAD129, HAD130, HAD131 and HAD132 which were completed early in the Quarter and have been previously reported. The results reported here are from 4 new drill holes comprising 3,680m of drilling, and 26 drill holes previously reported holes comprising 16,449m of drilling. Selected significant intercepts are presented in Table 1.
