Redcastle Resources reports outstanding high-grade gold intercepts from ongoing drilling at Redcastle Reef, reinforcing mineralisation continuity and supporting near-term mine planning.
- Over 6,500 assay results from 134 new drillholes
- Exceptional intercepts including 10m @ 50.11 g/t Au and 1m @ 311 g/t Au
- Grade control drilling approximately 88% complete
- Strong continuity of mineralised lode system confirmed
- Shallow high-grade nuggety gold offers potential for early cash flow
Exceptional Grade Control Drilling Results
Redcastle Resources Limited has released a new batch of assay results from its ongoing grade control drilling program at the Redcastle Reef deposit in Western Australia's Eastern Goldfields. The latest data, comprising over 6,500 assays from 134 drillholes, reveals multiple robust high-grade gold shoots, including standout intercepts such as 10 metres at 50.11 grams per tonne gold starting from just 12 metres depth, and a remarkable 1 metre intercept grading 311 grams per tonne gold.
These results build on previous drilling efforts and confirm the presence of a coherent mineralised lode system with strong continuity at mining scale. The drilling program is now approximately 88% complete, with a total of 7,110 metres drilled to date, representing more than half of the planned 12,800 metres designed to refine grade definition for mine planning and production.
Geological Confidence and Nuggety Gold Characteristics
The high-grade intercepts support Redcastle's current geological interpretation, showing consistent lode geometry and repeatable higher-grade zones across multiple adjacent sections. Notably, the footprint of very high-grade mineralisation exceeds that observed in the original Mineral Resource Estimate drilling dataset.
The deposit is characterised by nuggety gold, a coarse gold style known to cause variability in assay results. This nuggety nature is evident in the exceptionally high assay values, which are uncut and subject to adjustment in future resource estimations. The presence of shallow high-grade nuggety gold near surface is particularly encouraging, as it mirrors the style found at Redcastle's Queen Alexandra deposit, potentially enabling early access to high-grade ore with limited overburden removal.
Implications for Mine Planning and Production
Chairman Ron Miller highlighted that the expanded grade control dataset will underpin near-term mine planning and operational decisions. The drilling confirms well-defined high-grade shoots within the eastern sections of the deposit, with intercepts of significant width and grade reinforcing confidence in the geological model.
With the drilling program nearing completion, Redcastle plans to integrate all assay results into an updated mine model to support production activities in 2026. The company is also undertaking confirmatory check assays on exceptionally high-grade intervals to ensure accuracy and reliability.
Quality Assurance and Forward Outlook
Samples were analysed by fire assay at Bureau Veritas in Kalgoorlie, with rigorous quality control measures including certified reference materials and blanks confirming the reliability of assay data. The drilling orientation and sampling methods are industry standard, ensuring representative results.
Looking ahead, Redcastle Resources and its joint venture partner BML Ventures continue to advance the project, subject to approvals and commercial decisions. The company is evaluating additional data acquisition and plans to update the Mineral Resource Estimate once all grade control assays are received and validated.
Bottom Line?
As Redcastle Reef’s grade control drilling nears completion, the stage is set for a resource update that could unlock significant value and shape near-term production plans.
Questions in the middle?
- How will the nuggety nature of gold at Redcastle Reef affect final resource estimates and mining recovery?
- What is the timeline for integrating all assay results and updating the Mineral Resource Estimate?
- How might these high-grade intercepts influence the joint venture’s production scheduling and early cash flow?
