Highlights
- West Dome Underground shows expanding high-grade zones
- Three mineralised domains confirmed
- Proximity to Telfer infrastructure enhances development
Greatland Resources Ltd (ASX:GGP) has reported a series of broad gold-copper intercepts at the West Dome Underground (WDU) within the Telfer region, strengthening the profile of this emerging ASX mining stocks opportunity. The latest drilling confirms the continuity of high-grade mineralisation and expands the footprint of the project. These developments are set to contribute meaningfully to the evolving landscape of the ASX stock market.
Phase 2 Drilling Program Advances
The Phase 2 drilling program at West Dome Underground has made significant progress, with multiple holes completed, highlighting expanding mineralised zones and high-grade sectors in the southern area. The drilling aims to support an upcoming maiden Mineral Resource Estimate (MRE), which is expected to provide clarity on the scale and grade distribution across the underground project.
Three Mineralised Domains Identified
As drilling intensity increases, Greatland Resources has confirmed three distinct mineralised domains within the West Dome system:
Western Stockwork Corridor (WSC)
The WSC demonstrates broad widths and significant down-dip continuity. Mineralisation extends across a substantial strike length, illustrating the scale of the underground opportunity. The stockwork nature of the corridor indicates a strong potential for consistent gold-copper mineralisation.
Western Limb
The Western Limb continues to show robust mineralisation over an extensive strike length. Drilling has identified high-grade zones, confirming the limb as one of the primary targets within WDU. The Western Limb is proving to be a key contributor to the overall high-grade potential of the underground system.
Eastern Limb
The Eastern Limb is emerging as a secondary high-grade target. Drilling results indicate mineralisation comparable to the Western Limb, reinforcing the potential for multiple high-grade sectors within West Dome. Both limbs remain open along strike and down dip, suggesting future expansion possibilities.
Leveraging Telfer Infrastructure
The WDU project benefits from its proximity to the existing Telfer underground operations. Infrastructure, including haulage systems, crushing facilities, ventilation, and power supply, offers considerable support for advancing WDU development. The Main Dome Underground (MDU) has spare capacity, providing an efficient pathway for integrating West Dome ore into the existing system.
A pre-feasibility study is underway to evaluate how WDU can utilise MDU's infrastructure effectively. This includes assessing underground crushers, hoisting shafts, and ventilation, while also considering processing optimisations alongside future Havieron ore sources.
Development Progress
Work continues to expand underground access, including a parallel drive from MDU toward WDU. Completion of this access will enable higher drilling rates and flexibility for early development works. The expansion underscores the operational synergy between West Dome and existing Telfer facilities, facilitating a smoother path toward production readiness.
Strategic Significance
West Dome Underground represents an extension of Telfer’s mining profile, offering access to additional high-grade mineralisation zones. The ongoing drilling highlights substantial widths and consistent grades, enhancing the underground project’s strategic importance. Access to these zones could open a new phase of underground operations within Telfer, complementing the existing open pits and contributing to long-term operational depth.
Greatland Resources is positioning the West Dome Underground project as a significant addition to the Telfer mine. Continuous drilling success, three confirmed mineralised domains, and access to existing infrastructure are all reinforcing the project’s high-grade potential. With a focused development approach, West Dome Underground is on track to become a notable contributor within the ASX100 and ASX300 landscape.
