Strategic Optimization Underway for Western Queen Gold Mine
Rumble Resources Limited (ASX: RTR) is making significant progress towards developing its Western Queen Gold Project, with key advancements in mine planning, permitting, and potential revenue diversification. Managing Director Peter Harold confirmed the company is optimizing mining approaches while preparing to submit regulatory approvals for the open pit development.
The company is strategically positioning itself to maximize returns from the project through:
- Optimizing open pit mine plans to improve economics
- Exploring underground mining options as an alternative approach
- Advancing discussions with third-party processing facilities
- Investigating an additional revenue stream from tungsten mineralization
- Considering a royalty sale for upfront capital
"The Western Queen gold mine project is progressing towards development," stated Peter Harold, Managing Director and CEO. "Optimisation of the proposed open pits is underway and at the same time we are undertaking an underground proof of concept study to compare the working capital requirements and economics of the different mining methods."
Mining Studies: Balancing Capital Requirements and Returns
Open Pit Development Reconfiguration
Rumble's mine planning partner MEGA Resources has revised the preliminary open pit development plan following geotechnical assessment of the Western Queen South deposit. Key modifications include:
- Adjusted pit wall angles resulting in increased strip ratios
- Rescheduled sequencing of smaller pits (Duke, Cranes, Princess) to later in the development timeline
- Higher initial working capital requirements beyond the originally planned $35 million facility ($25M working capital + $10M cost overrun)
The company is now conducting re-optimization work to maximize free cash flow while determining the final upfront capital requirements to be provided by financing partner Bain Global Resources.
Underground Alternative Under Consideration
In response to higher capital demands for the open pit scenario, Rumble has initiated a "proof of concept" underground mining study for the Western Queen South deposit. This parallel assessment aims to:
- Compare capital efficiency between open pit and underground approaches
- Potentially reduce initial working capital requirements
- Determine if underground mining offers superior economic returns
If the preliminary underground evaluation proves favourable, the company will develop a more comprehensive underground mine plan.
| Mining Approach | Current Status | Key Considerations |
|---|---|---|
| Open Pit | Re-optimization in progress | Higher strip ratio, increased capital needs |
| Underground | Proof of concept study | Potential for lower upfront capital |
Processing Strategy and Regulatory Advancement
Multiple Processing Pathways Under Evaluation
Rumble continues discussions with owners of operational gold processing plants near Western Queen. The company has:
- Shared its updated open pit mining schedule (May 2025) with potential processing partners
- Received feedback from these operators on the proposed development
- Initiated discussions with owners of currently inactive processing plants that could be refurbished by 2026
This multi-faceted approach gives Rumble flexibility in determining the optimal processing solution once mining commences.
Permitting on Track for June Submission
The regulatory approval process is advancing steadily, with MEGA Resources preparing:
- Mining Proposal documentation
- Mine Closure Plan
- Works Approval application
- Additional ancillary permits required for open pit development
Rumble anticipates submitting these materials to relevant authorities in early June 2025, marking a significant milestone toward project development.
Unlocking Additional Value Streams
Tungsten Resource Potential
A particularly interesting development is Rumble's work to establish a tungsten resource at Western Queen South alongside the gold mineralization. Progress includes:
- Resource estimation utilizing 2024-2025 drilling data and historical core assays
- Maiden tungsten resource expected in Q3 2025
- Preliminary metallurgical testing indicating significant potential revenue
- Preparation of bulk samples for detailed recovery testing by mineral separation specialists
"Work continues on the resource estimation and the metallurgy of the tungsten mineralisation at Western Queen South to determine whether a tungsten revenue stream can be generated," noted Mr. Harold. "The maiden tungsten resource should be available during the September quarter."
Royalty Monetization Opportunity
Rumble is exploring an innovative financing option through the sale of an additional gold royalty:
- Current gold royalty on the project is minimal at just A$6-20 per ounce
- Opportunity to sell an additional 1-2% Net Smelter Return (NSR) royalty
- Non-binding indicative offer received from a specialty royalty company
- Would provide immediate working capital with minimal impact on future project cash flows
Understanding Net Smelter Return Royalties: A Key Mining Finance Tool
Net Smelter Return (NSR) royalties are a common financing mechanism in the mining industry that allows project owners to access immediate capital while maintaining operational control.
An NSR royalty gives the holder the right to receive a percentage of revenue from mineral production, calculated after deducting smelting, refining, and transportation costs. Unlike a gross royalty, it accounts for processing costs but is applied before operating costs and taxes.
For investors, NSR royalties are significant because:
- They provide exposure to project upside without operational risks
- They typically survive through the entire life of a mine, regardless of ownership changes
- They offer inflation protection as commodity prices rise
- They enable companies like Rumble to access non-dilutive financing
In Rumble's case, the existing gold royalty of A$6-20 per ounce is well below industry averages, creating an opportunity to monetize this gap while minimizing impact on future cash flows.
Cooperation Agreement Extension
The development partnership between Rumble, Bain Global Resources, and MEGA Resources continues to advance, though with adjusted timelines:
- Core cooperation agreement has been fully negotiated
- Supporting agreements (Primary Facility, Security Deed, Mining Services) in various drafting stages
- Execution timeline extended to September 30, 2025 to accommodate optimization studies
- All parties remain committed to maximizing project returns
This extension allows Rumble to incorporate findings from the ongoing optimization work, underground studies, tungsten metallurgical testing, and processing options assessment before finalizing the definitive agreements.
