Greatland Gold PLC (AIM: GGP, OTC: GRLGF) CEO Shaun Day has hailed the first underground drilling results from the West Dome project as “exceptional,” reinforcing the potential for high-grade gold and copper beneath the Telfer West Dome open pit.
Of the 19 drill holes, 16 intersected significant mineralisation, with an average intercept of 23.2 metres grading 2.95 grams per tonne of gold and 1.07% copper—equivalent to 4.23 grams per tonne of gold.
A standout drill result included an intercept of 14.3 metres at 9.06 grams per tonne of gold and 8.57% copper.
The findings confirm that high-grade mineralisation extends over 700 metres and remains open in multiple directions, indicating strong potential for resource expansion through further drilling.
Greatland also highlighted that West Dome shares the same geological characteristics as the nearby Main Dome underground mine, which has already yielded over 3.1 million ounces of gold and 210,000 tonnes of copper.
Highlights
- Maiden West Dome Underground diamond drilling program completed in December 2024 quarter with all results now returned and interpreted.
- 16 of the 19 holes drilled in this program intercepted >50 gram-metres Au (gm), with the average down hole intercept from these 16 holes of 23.2m @ 2.95g/t Au and 1.07% Cu (4.23g/t AuEq1)
- Exceptional results included:
‒ 14.3m @ 9.06 g/t Au and 8.57% Cu (19.34 g/t AuEq) from 290.4m
‒ 59.0m @ 2.83 g/t Au & 0.71% Cu (3.68 g/t AuEq) from 259.0m
- Mineralisation identified over 700m of strike and remains open along strike and down dip
- Drilling confirms high grade mineralisation in the West Dome Underground is associated with the same geological units seen at the active Main Dome Underground, which has produced more than 3.1Moz gold and 210kt copper to date
- Existing infrastructure supports the economics of a potential West Dome Underground Project and would accelerate its development
- Second phase drilling program planning underway
Greatland Managing Director, Shaun Day, commented:
“The exceptional drilling results from the maiden underground drilling campaign validate the exciting opportunity we identified at the West Dome Underground during our acquisition due diligence.
“The Main Dome Underground began production in mid 2006 and continues operating today, almost 20 years later, having produced more than 3 million ounces of gold to date. This underground drilling campaign is the first since driving across to gain access beneath the West Dome.
“The West Dome Underground drilling delivered high grades and equally importantly, excellent widths. They confirm that key geological units hosting the Main Dome Underground mineralisation are present in the West Dome Underground. Mineralisation remains open along strike and down dip, and we intend to increase our confidence of the initial body as well as continue to test extensions in our further work.
“A primary focus for us at Telfer is mine life extension, and these results confirm the West Dome Underground Project as a very high priority target for us. We are planning a second phase drilling program, including geotechnical and hydrogeological testing to support planned mine studies. If we continue to have exploration success, the ability to leverage the existing underground infrastructure at Telfer, including the haulage shaft, provides the opportunity to rapidly advance development of the West Dome Underground.”
Extending Telfer’s mine life remains a key priority, and these results establish West Dome Underground as a leading exploration target, according to CEO Shaun Day.
Planning is already underway for a second phase of drilling, which will include geotechnical and hydrogeological testing to support mine studies. If exploration continues to yield positive outcomes, existing underground infrastructure, such as the haulage shaft, could enable an accelerated development timeline.
