Rumble Resources Limited has upgraded its Western Queen Gold Project, now estimating 370,000 oz gold at an average grade of 3.1g/t—a substantial boost in both resource volume and grade. This promising update opens new avenues for further exploration and potential underground mining initiatives.
Rumble Resources Limited has reported a major upgrade to the Western Queen Gold Project’s mineral resource, with the revised estimate now standing at 3.72 million tonnes at 3.1g/t Au, amounting to 370,000oz of gold. This new figure reflects a 29% increase in contained ounces and a 53% increase in head grade compared to earlier estimates, thanks to an additional 8,205m of reverse circulation drilling and 2,453m of diamond drilling carried out between November 2024 and March 2025.
The improvement is most significant at the Western Queen South deposit, where the revised resource now totals 2.32 million tonnes at 2.66g/t Au, representing a 59% increase in ounces. Updated wireframes and enhanced geological interpretations led to improved grade estimations, with the indicated category grade rising from 1.8g/t to 3.0g/t Au. This technical refinement, made possible by incorporating stronger geological controls from recent drilling and surface mapping, has driven the project’s potential to explore both open pit and underground mining options. The project benefits from its placement within granted mining leases and proximity to five operational gold processing facilities within a 200km radius.
The update is supported by robust technical criteria, including block modelling with a parent block size of 5m by 1m by 1m, a cut-off grade of 0.5g/t Au for open pit resources above the 245m reduced level and 1.5g/t Au below that level for underground targets, and the use of Ordinary Kriging for grade interpolation. Historical mining at the Western Queen deposits has produced over 215,000oz, demonstrating both the project's long-standing production potential and the importance of its strategic geological setting.
The news carries a predominantly bullish sentiment. The upgraded resource estimates, improved grade profiles, and the commencement of an underground mining study underscore strong near-term development potential that could drive positive cash flow. On the technical front, the additional drilling campaigns and reclassification of resources pave the way for increased project economics and future exploration infill drilling to convert Inferred resources to the higher confidence Indicated category. However, there remain some bearish aspects given that the full economic viability will depend on comparing the open pit and underground mining options, and further detailed feasibility studies are needed to address capital requirements and operational risks.
