Redcastle Resources Limited has released a comprehensive technical report detailing updated mineral resource estimates for its Queen Alexandra and Redcastle Reef deposits. The update reflects the latest results from extensive reverse circulation and diamond drilling programs, with the combined resource now featuring significant volumes of indicated and inferred gold mineralisation. Key technical parameters include a nominal 1 g/t Au cut‐off for open pit evaluation, metallurgical recovery assumptions of 92%, and a gold price benchmark of AU$4,800 per ounce. The report highlights that the Queen Alexandra deposit now benefits from denser drilling data on a 20m by 20m grid, while the Redcastle Reef deposit has been similarly modelled with attention to historical drill data and contemporary sampling techniques. The technical evaluation employed advanced block modelling methods using ordinary kriging and inverse distance algorithms, with careful attention to geological continuity, shape dilution, and high-grade cut-offs applied to the most extreme assay values. Detailed conceptual pit designs derived from Whittle optimization studies suggest that both deposits have robust near-term potential for open pit development. The modelling incorporates multiple material types—from oxide through transition to fresh rock—with bulk density measurements ranging from 1.9 to 2.9 t/m³, ensuring that tonnage estimates are reported on a dry basis. Extensive appendices document drilling collar layouts, geological sections, intersection data, and resampling procedures, reinforcing the technical robustness of the resource estimate. Investors may view this news with a positive outlook. The updated estimates not only show an increase in both the volume and confidence levels (with sizable indicated categories within economic pit shells) but also point to potential cost savings through co-development opportunities and partnering arrangements. The methodological rigor and detailed geostatistical work underpin a clear path to future production and resource growth, which is encouraging for long-term value creation. Conversely, caution is warranted given that a significant portion of the resource remains in the inferred category and further work—including detailed scoping studies, diamond drilling to confirm geotechnical parameters, and additional economic analysis—is required before the mineral resources can be converted to reserves. This means near-term capital requirements and project timelines remain subject to further refinement, which may temper enthusiasm among more risk-sensitive investors.
