Greatland Gold provides Havieron exploration and development update

Highlights

• Seven drill rigs currently on site, all focused on growth targeting:
  • South East Crescent: continuous mineralisation identified across 1000 vertical m and remains open. Drilling continuing to progressively test for extensions to the South East Crescent, with drilling planned up to 400 m below the updated mineral resource.
  • Eastern Breccia: drilling continuing to define the greater mineralised footprint of the Eastern Breccia, including definition of higher-grade zones recently announced.
  • Northern Breccia: drilling aimed at extending high-grade zones of mineralisation at depth.
  • New Targets: drilling continuing to define geophysical targets outside of the main Havieron system with follow-up drilling planned at regional targets on the Havieron mining lease.

New drilling results

• Drilling in the South East Crescent has extended the high grade zone down a further 100 m with Crescent zone having now been continuously intersected to over 1000 vertical m (3800 m RL2) and remaining open at depth:
  • HAD133W9: 85.8 m at 3 g/t gold (Au) and 0.06% copper (Cu) from 1604 m and 25.3 m at 1.1 g/t Au and 0.08% Cu from 1471.1 m.
• High grade results in the Northern Breccia reinforce the potential for further high-grade sulfide mineralisation adjacent to the South East Crescent Zone:
  • HAD055W4: 149.9 m at 2.7 g/t Au and 0.12% Cu from 877.4 m, including 13.9 m at 22.8 g/t Au and 0.46% Cu from 1013.4 m.
  • HAD055W5: 39.6 m at 2.8 g/t Au and 0.07% Cu from 983.6 m, including 0.5 m at 96 g/t Au and 0.1% Cu from 1020.7 m.
• Early Works improvements: Construction activities by Newcrest are progressing including:
  • An exploration decline advance of 377.5 m as at end of May 2022.
  • Fuel facility fully commissioned.

The decline experienced improved ground conditions in the June quarter. Advance rates have improved after changes in the design of the decline brought forward the first downward spiral to the current advance position. This has allowed the decline to transition into better ground conditions. The Havieron fuel facility has now been completed and commissioned into operation.

• Feasibility study work by Newcrest is progressing and key contracts have been awarded. The feasibility study is still forecast to be delivered in the December 2022 quarter.

Shaun Day, Managing Director of Greatland Gold plc, commented: “The growth drilling programme continues to expand Havieron‘s mineralised system. The existing high grade mineralised zone of the South East Crescent now extends a further 100 m below our previous mineral resource estimate. Testament to the scale of Havieron, there is now continuous mineralisation observed over 1000 m of vertical extent with the system remaining open at depth.

“With an extensive growth drilling programme planned over the next 12 months, there is tremendous potential to further expand the Havieron resource and unlock the true scale and value of the broader system.

“Pleasingly, the decline has encountered better ground conditions, resulting in recent improvements to the decline advancement rates.”
