Greatland Gold has provided a development update and a mineral resource estimate on the Havieron project it shares with Newcrest Mining.
Havieron is a high-grade gold-copper project centred on a deep magnetic anomaly located in Western Australia, approximately 485 kilometres southeast of Port Hedland and 45 kilometres east of Telfer. It is a joint venture between Greatland (30 per cent) and Newcrest (70 per cent).
Greatland has announced that Havieron’s main decline continues to progress, having surpassed 1840 metres. The decline support excavations for ventilation, services and materials handling have taken the total development to over 2600 metres.
“The decline has continued to progress through improved ground conditions since successfully developing through the middle aquifer late last month,” the company said.
Greatland also announced that over 80,000 metres of growth drilling has been completed at Havieron since Greatland announced Havieron’s mineral resource estimation (MRE) in March 2022.
Greatland has since focused on defining the extents of mineralisation in the lower levels of the SE Crescent, resource definition within the lower levels of the mineralised system with a focus on the Eastern Breccia, and extending the mineral system below the existing resource.
The company said the work programs required to incorporate the drill results into an updated Havieron MRE are currently in progress.
Greatland Gold managing director Shaun Day said the underground development at Havieron is making good progress as the company continues to advance to the top of the orebody.
“We are working towards the publication of an updated MRE, which will incorporate data from a further 80,000 metres of growth drilling at Havieron since our March 2022 MRE update,” Day said.
“We are targeting completion and announcement of an updated MRE during the December 2023 quarter and look forward to updating the market in due course.”
