Crown Prince Drilling Yields 3m at 43.10g/t and 36.3m at 2.22g/t Gold
New Murchison Gold Limited reveals significant high-grade gold intersections well below the current open pit at its Crown Prince Gold Mine, signaling promising underground mining potential and an extended mine life.
- High-grade drill intersections including 3m at 43.10g/t Au and 36.3m at 2.22g/t Au
- Mineralisation extends 75m below current open pit design
- Open pit mining progressing with ore deliveries to Westgold’s Bluebird plant
- Processing plant commissioning scheduled for September 2025
- Plans underway for resource update and underground feasibility study
Exploration Breakthrough at Crown Prince
New Murchison Gold Limited (ASX, NMG) has announced compelling results from its latest diamond drilling program at the Crown Prince Gold Mine, part of its flagship Garden Gully Gold Project near Meekatharra, Western Australia. The company reported high-grade gold intersections well below the existing open pit, including a standout 3 metres at 43.10 grams per tonne (g/t) gold and a broader 36.3 metres at 2.22 g/t gold. These results confirm that the mineralised zones continue at depth, expanding the underground mining potential beyond the current mine plan.
Extending the Resource Envelope
The drilling targeted the south-eastern and northern zones of mineralisation, areas previously outside the current Mineral Resource Estimate. Notably, the high-grade intercept of 3m at 43.10 g/t gold was encountered 75 metres below the base of the ultimate pit design, underscoring the potential for deeper ore shoots. Another hole intersected a continuous 36.3m zone averaging 2.22 g/t gold at 367.5 metres depth, the deepest drilled into the South-Eastern Zone to date. These findings suggest a robust and persistent mineralised structure that could support a transition to underground mining.
Operational Progress and Future Plans
Meanwhile, surface operations are advancing steadily. Open pit mining is underway with ore being delivered to Westgold Resources Limited’s Bluebird Gold Processing Plant, which is on track to commence processing in September 2025. This operational momentum complements the exploration success, positioning New Murchison Gold to move towards production.
CEO Alex Passmore highlighted the significance of these results, stating they enhance confidence in the resource inventory and underpin plans for a resource update and an underground feasibility study. These studies will be critical in defining the economic viability of mining extensions and shaping the company’s development strategy beyond the current 30-month open pit mine life.
Geological Context and Exploration Methodology
The Crown Prince deposit is hosted within a package of mafic rocks, including schists and basalts, with gold mineralisation associated with quartz-carbonate veins and alteration zones. The recent drilling program employed diamond core techniques to test mineralisation continuity at depth, with rigorous sampling and assay protocols ensuring data quality. The geological model interprets the mineralisation as steeply plunging shoots within an anticlinal structure, favorable for underground extraction.
Looking Ahead
New Murchison Gold is also investigating satellite deposits near Crown Prince as potential future development options, indicating a broader growth pipeline within the Garden Gully project. The company’s comprehensive tenure package and ongoing exploration efforts position it well to capitalise on the Murchison goldfield’s prolific potential.
Bottom Line?
With high-grade mineralisation confirmed at depth, New Murchison Gold is poised to extend Crown Prince’s mine life and transition towards underground operations.
Questions in the middle?
- How will the upcoming resource update and feasibility study impact the mine’s economic outlook?
- What is the timeline and scale for developing satellite deposits near Crown Prince?
- How might operational ramp-up at the Bluebird processing plant influence production forecasts?
