Rumble Resources Ltd
Rumble Resources Limited (ASX: RTR) recently presented to investors at the RIU Explorers Conference in Fremantle, outlining a compelling dual-track strategy that combines near-term gold production potential with significant exploration upside across multiple commodities. The presentation highlighted the company's evolution from explorer to potential producer, with Western Queen's upgraded gold resource of 370,000oz at the centre of a broader multi-asset portfolio.
The company's latest investor presentation reinforces its positioning as a near-term cash flow generator through the Western Queen project while maintaining substantial exploration leverage across gold, tungsten, zinc, lead, and silver assets in Western Australia's premier mining districts. This comprehensive approach forms the foundation of Rumble Resources growth strategy 2026, demonstrating the company's commitment to balanced value creation.
Western Queen Gold Project: From Resource Growth to Production Timeline
Resource Expansion Delivers Grade and Scale Improvements
Rumble's flagship Western Queen project has demonstrated exceptional resource growth, with the latest mineral resource estimate showing 3.72Mt @ 3.1g/t Au for 370,000oz – representing a 53% grade increase and 29% increase in contained gold ounces compared to previous estimates.
| Resource Milestone | Tonnage | Grade | Contained Gold |
|---|---|---|---|
| October 2024 | 3.6Mt | 2.5g/t | 287,000oz |
| July 2025 | 3.72Mt | 3.1g/t | 370,000oz |
| Improvement | +3% | +24% | +29% |
The project benefits from proven historical production of 880kt @ 7.6g/t Au for 215,000oz, providing confidence in the deposit's commercial viability and metallurgical characteristics.
Scoping Study Confirms Robust Economics
The Western Queen South Scoping Study, released in November 2025, validates the project's near-term production potential with compelling economics:
Key Financial Metrics:
- Production Target: 617kt @ 2.95g/t for 58,500oz Au
- Free Cash Flow: $133 million
- NPV (8%): $112 million
- IRR: 370%
- AISC: A$2,970/oz
- Upfront Capex: ~$10 million
- Timeline to Production: 6 months from portal to first ore
The study's conservative gold price assumption of A$5,540/oz provides significant upside potential given current spot prices of A$6,400/oz. Importantly, the production target utilises only 29% of Western Queen South resources and excludes the Western Queen Central deposit entirely, indicating substantial mine life extension potential.

Current Drilling Campaign: 20,000m Programme Targeting Resource Growth
Rumble has commenced an ambitious 20,000m diamond drilling programme designed to achieve multiple value-adding objectives:
Primary Drilling Objectives
- Resource Discovery: Targeting high-grade down-plunge extensions to WQ South and Central deposits
- Resource Classification: Converting Inferred to Indicated resources for mine planning
- Tungsten Expansion: Discovering additional tungsten resources for potential co-product revenue
- Geotechnical Assessment: Evaluating underground mining conditions
- Metallurgical Validation: Confirming +93% gold recovery rates
Recent Drilling Highlights
Western Queen South Extensions:
- 12.2m @ 5.13g/t from 456m including 2.2m @ 23.70g/t from 466m
- 22.7m @ 2.84g/t Au from 203.3m including 7.2m @ 6.00g/t Au from 213.8m
- 12m @ 3.40g/t Au from 283m including 3m @ 7.03g/t Au from 288m
Western Queen Central High-Grade Zone:
- 6.3m @ 24.88g/t from 305m
- 5.8m @ 30.72g/t from 314.6m
These results continue to validate the "Never Never analogy" – a comparison to Ramelius Resources' highly successful Never Never deposit, which hosts 7.76Mt @ 9.32g/t Au for 2.32Moz to 1,000m depth.
Understanding Mineral Resource Classification: Why Indicated Resources Matter
Mineral Resource Classification represents the confidence level in geological understanding and grade continuity. Resources are classified as Inferred, Indicated, or Measured based on drilling density and geological confidence.
Indicated Resources require closer-spaced drilling and demonstrate sufficient geological and grade continuity to support mine planning and economic evaluation. Converting Inferred to Indicated Resources is crucial for:
- Mine Planning Confidence: Enables detailed production scheduling
- Financing Requirements: Banks and investors prefer Indicated Resources for project funding
- Regulatory Approval: Mining permits often require Indicated Resource classification
- Risk Reduction: Lower geological uncertainty improves project economics
Rumble's current drilling programme specifically targets this classification upgrade, with 66% Indicated and 34% Inferred Resources already incorporated in the Western Queen South mining inventory.
Tungsten Opportunity: Maiden Resource with Expansion Potential
Maiden Tungsten Resource Establishes New Revenue Stream
In August 2025, Rumble announced its maiden tungsten resource of 13.2kt WO₃, adding a potential co-product revenue stream to the Western Queen operation. The resource demonstrates significant grades with zones containing:
- 4m @ 4.58% WO₃ including 2.05m @ 8.71% WO₃
- 26m @ 0.62% WO₃ over broader widths
- 11.5m @ 1.46% WO₃ in separate lodes
Strategic Tungsten Market Position
The tungsten resource positions Rumble in an attractive specialty metals market with strong supply-demand fundamentals. Tungsten's critical applications in aerospace, defence, and industrial tooling support robust long-term pricing, while the resource remains open for expansion through the current drilling programme.
| Rumble Western Queen | Benchmark Comparison |
|---|---|
| 13.2kt WO₃ (Maiden) | Almonty Sangdong: Multiple Resources |
| 1.44Mt @ 0.51% WO₃ | Industry Standard Grades |
| Expansion Potential | Established Producer Comparison |
Earaheedy Project: World-Class Base Metals Discovery
Globally Significant Zinc-Lead-Silver Resource
Rumble's Earaheedy project hosts one of the largest zinc sulphide discoveries globally over the past decade, with a maiden resource of:
- 2.2Mt Zinc
- 0.7Mt Lead
- 12.6Moz Silver
- Total Resource: 94Mt @ 3.1% Zn+Pb and 4.1g/t Ag
Development Partnership Strategy
The company is actively seeking a development partner for Earaheedy, recognising the project's large-scale, low-cost open pit mining potential. Metallurgical testwork has confirmed:
- High recoveries with +60% Zn+Pb concentrate grades
- HyroFloatâ„¢ technology compatibility reducing plant costs
- Bulk concentrate specifications suitable for industry smelters
The 41Mt higher-grade component (>3% Zn+Pb cut-off) provides optionality for staged development while less than 30% of the 70km host formation has been effectively tested, indicating exceptional resource growth potential.
