Highlights
- High-grade gold intercepts confirmed at multiple projects, showcasing strong mineralisation potential.
- Additional drilling at Queen Alexandra supports an open-pit operation and possible underground expansion.
- Maiden resource estimate underway for Redcastle Reef with potential satellite mining prospects.
Redcastle Resources (ASX:RC1) has reported significant high-grade gold intercepts across its Queen Alexandra, Redcastle Reef, and Morgan’s Castle East projects in Western Australia’s eastern goldfields. These results stem from an additional 1,700 meters of reverse circulation (RC) drilling, complementing an earlier 6,500-meter program completed under budget.
The drilling program, covering 99 holes for a total of 9,700 meters, confirmed widespread gold mineralisation, reinforcing the exploration potential across these projects.
Encouraging Results from Queen Alexandra
At the Queen Alexandra prospect, some of the most promising results included 4 meters at 10.94 grams per tonne (g/t) gold from just 6 meters depth and 4 meters at 4.79g/t gold from 8 meters. These results were found in a previously undrilled northern section of the prospect, indicating untapped mineralisation.
Notably, the newly identified Kestrel Lode returned multiple high-grade intercepts, such as:
- 7m at 10.16g/t gold from 42m,
- 3m at 6.43g/t from 15m,
- 2m at 7.78g/t from 77m, and
- 3m at 5.07g/t from 20m.
These findings have prompted an additional 17 drill holes and a scoping study to evaluate the potential for an open-pit operation, with further underground expansion being considered through third-party toll processing.
Advancing Redcastle Reef Towards Maiden Resource Estimate
Following strong drilling results at Redcastle Reef, the company is now working towards its maiden mineral resource estimate. Notable intercepts include:
- 2m at 9.14g/t gold from 39m, and
- 8m at 3.06g/t gold.
Redcastle Reef is being considered as a potential satellite open-pit operation that could complement Queen Alexandra’s development.
Morgan’s Castle East Shows Strong Potential
Reconnaissance drilling at Morgan’s Castle East confirmed a gold-mineralised structure within an oxide zone, with a potential east-west strike length of 400 meters. Key results included:
- 1m at 22.5g/t gold from 36m, and
- 1m at 6.12g/t gold from 27m.
The presence of soft oxide and transition material suggests potential for low-cost mining operations in the area.
Strategic Outlook and Exploration Expansion
Chair Ray Shaw emphasized the significance of these discoveries, highlighting the potential for an extensive east-to-west gold corridor.
“We now see the possibility of a mineralised corridor with Queen Alexandra at its core, extending eastward to Coronation, Redcastle Reef, and Morgan’s Castle East,” Shaw stated. “With continued exploration, this corridor could extend even further, covering approximately 2.5km.”
These latest drilling results have strengthened the company’s confidence in the project’s long-term potential, setting the stage for further development and resource expansion.
