Greatland Gold plc (AIM: GGP), the precious and base metals exploration and development company, is pleased to provide an update on activities at the Havieron gold-copper project in the Paterson region of Western Australia.

The Company notes the release of an ASX announcement titled 'Exploration Update' by Newcrest Mining Ltd ('Newcrest') earlier today.

Drilling activities since the last report include new results from the ongoing Growth Drilling programme, which continue to support the potential for resource expansion of the Havieron system.

The latest results consist of seven new drill holes from the Growth Drilling programme. Newcrest has now completed a total of 164,420m of drilling from 190 holes to date, with all the latest holes continuing to intersect significant mineralisation.

Highlights

Excellent results from Growth Drilling continue to support the potential for resource expansion within the Havieron gold-copper mineralised system

High-grade intercepts below the December 2020 Initial Inferred Mineral Resource shell in the South East Crescent Zone and adjacent Breccia Zones, and around the Northern Breccia.

HAD133 returned 85m @ 11g/t Au & 0.29% Cu from 1345m, including 13m @ 32g/t Au & 0.46% Cu from 1363m, and 14.5m @ 32g/t Au & 0.33% Cu from 1396.5m1.

High-grade Crescent Zone remains open at depth.

Additional mineralisation identified in Northern Breccia Zone, highlighting the potential for resource extensions outside the existing resource shell.

New drill intercepts from within the 2020 Initial Inferred Mineral Resource shell support geological and grade continuity

Additional high-grade South East Crescent intercepts from within the December 2020 Initial Mineral Resource.

These results support the delivery of an Indicated Mineral Resource estimate in the South East Crescent Zone.

2021 Growth Drilling is progressing into FY22

North West Crescent and Northern Breccia: Growth Drilling continues to focus on the North West Crescent and Northern Breccia zone and aimed at providing support for the potential expansion of the existing Inferred Mineral Resource Estimate.

Eastern Breccia: Drill testing and interpretation of the geological and mineralisation controls of the Eastern Breccia Zone is ongoing.

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.

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 previously announced, surface earthworks are largely complete, with the box cut complete and decline development commenced: Excavation of the box cut commenced on 8 February 2021.

Commencement of the underground decline access, from the base of the box cut, was announced on the 12 May 2021.

The Joint Venture is progressing the necessary approvals and permits for the development of an operating underground mine (subject to a successful exploration program, feasibility studies, market and operating conditions, board approvals and a positive decision to mine).

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: 'These latest drilling results add further extensions to the high-grade mineralisation at Havieron while evolving the deposit beyond the existing resource shell. With each new set of excellent intercepts, we demonstrably advance the potential size and value of the gold-copper orebody at Havieron.

'Development on site continues at pace with surface earthworks nearing completion and the underground decline underway. As the Joint Venture progresses, ongoing exploration continues to enhance the potential scale of the gold-copper mineralised system at Havieron.'

Analytical results for new drilling from HAD086W1, HAD089W1, HAD096W1, HAD097W3, HAD106W2, HAD133, and HAD136 have been received and are announced today. The results reported here are from seven new drill holes comprising 5,757m of drilling completed since 31 March 2021, with all holes intersecting mineralisation.

Background to Havieron and Joint Venture Agreement with Newcrest

The Havieron Project is operated by Newcrest under a Joint Venture Agreement with Greatland. As announced on 30 November 2020, Newcrest has now met the Stage 3 expenditure requirement (US$45 million) and is entitled to earn an additional 20% joint venture interest, resulting in an overall joint venture interest of 60% (Greatland 40%). Newcrest can earn up to a 70% joint venture interest through total expenditure of US$65 million and the completion of a series of exploration and development milestones (including the delivery of a Pre-Feasibility study) in a four-stage farm-in over a six year period that commenced in May 2019. Newcrest may acquire an additional 5% interest at the end of the Farm-In period at fair market value.

The Joint Venture Agreement includes tolling principles reflecting the intention of the parties that, subject to a successful exploration programme, Feasibility Study and a positive decision to mine, the resulting joint venture mineralised material will be processed at Newcrest's Telfer operation, located 45km west of Havieron.
