Greatland Resources has confirmed growing opportunities at its West Dome Underground project following ongoing drilling.
The company has now completed 19 holes for more than 9000 metres as part of its Phase 2 drilling program, with results received from nine holes. The drilling program has largely focused on growth drilling for the first half of the fiscal 2026 year, targeting the southern extension of mineralisation.
The increasing drill density has confirmed three mineralised domains: a broad Western Stockwork Corridor (WSC), with extensive Wester Limb and Eastern Limb high-grade shoots within the Lower Limey Unit (LLU)
Recent drilling returned broad, high-grade intersections across the WSC, including 82.2m at 1.90 grams per tonne (g/t) gold and 0.31 per cent copper from 360.7m, 56.6m at 2.24g/t gold and 1.26 per cent copper from 337m and several additional wide zones between 40–70m true width.
In addition, high grade mineralisation continues to be intercepted within the LLU across both the Eastern Limb and Western Limb, with mineralisation on both limbs now over 500 metres in strike and remain open.
Greatland Managing Director, Shaun Day said: “Access to the West Dome Underground effectively opens access to a new quartile of the Telfer mine, being the two open pits and potentially the opportunity to start a second underground mine.
“The second development drive to the West Dome Underground is well progressed, and a pre-feasibility study is now underway and will assess how the substantial existing infrastructure capacity at the Main Dome Underground can be leveraged to deliver a pathway to production.”
The company expects a mineral resource estimate in the March 2026 quarter. Existing Telfer infrastructure supports the potential to accelerate a new mine at West Dome Underground.
A pre-feasibility study is underway and will assess the utilisation of the existing infrastructure at the Main Dome Underground.
