The successful commencement of Rox Resources underground mining operations at the Youanmi Gold Project represents a defining moment for the company's transformation from explorer to near-producer. On November 8, 2025, Rox Resources (ASX: RXL) achieved a critical milestone by firing its first decline cut at the United North pit, officially launching underground development at its 100%-owned Youanmi Gold Project. This achievement coincides with renewed confidence from debt providers, who have reaffirmed their indicative credit commitments, signalling strong project bankability as the Definitive Feasibility Study (DFS) approaches completion.
Furthermore, the underground development is being executed by Byrnecut Australia, delivered precisely according to the mobilisation plan. Following the successful first blast, the team is now preparing the batch plant for fibrecreting operations, which will enable continuous mining to commence within the coming week.
Strong Financial Backing Reinforces Project Viability
The timing of this operational milestone coincides with renewed confidence from the financial sector. Key Australian and international banks have provided updated credit-endorsed indicative commitments following their appraisal of initial due diligence packages and site visits to Youanmi.
Debt Financing Progress includes:
- Multiple updated indicative term sheets received
- Commitment amounts align with expected funding requirements
- Competitive terms offered across multiple lenders
- Final credit approvals expected following DFS release
This strong response from debt providers reflects the exceptional bankability of the Youanmi Gold Project. The project hosts a global mineral resource of 12.1Mt at 5.6g/t for 2.2Moz of gold, positioning it among the highest-grade undeveloped gold projects in Western Australia.
"We have officially commenced underground mining operations at our Youanmi Gold Project, with the first cut fired at the United North pit, marking a major milestone in our pathway towards production." – Managing Director & CEO Phill Wilding
Understanding High-Grade Gold Mining: Why Grade Matters
For investors new to gold mining, the concept of "grade" represents the concentration of gold within the ore body, measured in grams per tonne (g/t). Youanmi's 5.6g/t average grade is exceptionally high compared to many operating gold mines globally, which often operate at grades between 1-3g/t.
Why This Matters to Investors:
- Higher grades mean more gold extracted per tonne of ore processed
- Reduced processing costs per ounce of gold produced
- Enhanced profit margins and project economics
- Lower environmental footprint due to less waste rock handling
This grade advantage is crucial for Youanmi's competitiveness, particularly given current gold prices and rising operational costs across the mining sector. Furthermore, high-grade deposits typically require less infrastructure investment per ounce of gold produced, creating more efficient capital utilisation.
Underground Mining Fundamentals
Underground mining involves creating access tunnels, called declines, that lead to the ore body beneath the surface. The decline provides a pathway for equipment, personnel, and ore transport.
Fibrecreting is a process where concrete mixed with steel fibres is sprayed onto tunnel walls to provide structural support. This ensures safe working conditions as mining progresses deeper underground.
Pathway to Production: Clear Milestones Ahead
Rox Resources has outlined a comprehensive development timeline extending through 2027, with key operational milestones clearly defined:
| Phase | Timeline | Key Activities |
|---|---|---|
| Current (Q4 2024 – Q1 2025) | Now | Underground development commenced, DFS completion, debt finalisation |
| Development (Q2-Q4 2025) | Mid-2025 | Final Investment Decision, detailed engineering, long-lead item orders |
| Construction (Q1-Q4 2026) | 2026 | Mill construction and commissioning, full underground access |
| Production (Q1 2027+) | Early 2027 | First gold production, ramp-up to steady state |
Immediate Next Steps include:
- Release of updated reserves with the DFS
- Continue dewatering Main Pit operations
- Progress detailed engineering on process plant design
- Advance permitting for processing infrastructure
- Finalise project financing arrangements
The systematic approach to development demonstrates management's commitment to controlled risk management whilst maintaining aggressive timelines. However, each phase builds upon the previous milestone, creating multiple value inflection points for investors.
Investment Thesis: Premium Gold Project in Tier-1 Jurisdiction
Several factors position Rox Resources as a compelling investment opportunity in the gold development space. The project benefits from Western Australia's established mining framework, providing regulatory certainty and access to skilled labour markets.
Resource Quality & Scale
The Rox Resources underground mining operations showcase impressive fundamentals:
- 2.2 million ounces of contained gold at industry-leading grades
- Proven mining jurisdiction in Western Australia
- Existing infrastructure reducing development costs
- Multiple ore bodies providing operational flexibility
Operational Advantages
Key advantages include:
- Experienced management team with proven track records
- Established mining contractor partnerships (Byrnecut Australia)
- Strategic location near existing mining infrastructure
- Advanced metallurgical understanding through extensive test work
Financial Position:
- Strong debt appetite from multiple lenders
- Competitive financing terms available
- Clear pathway to production financing
- Low sovereign risk in stable jurisdiction
The project's high-grade, high-margin profile differentiates it from many development-stage gold projects, offering potential for superior returns in the current gold price environment. Additionally, the company's focus on the Albion Process for metallurgical treatment represents an advanced approach to gold extraction that could enhance recovery rates.
Technical Development Progress
The underground development at United North represents more than symbolic progress. The successful initiation of decline development demonstrates several critical factors.
Operational Readiness
Key achievements include:
- Contractor mobilisation completed on schedule
- Equipment and personnel positioned effectively
- Safety protocols implemented according to industry standards
- Technical expertise validated through successful blast execution
Infrastructure Advancement
Progress includes:
- Batch plant preparation underway for continuous concrete supply
- Ventilation systems being established for underground safety
- Power and communication infrastructure being installed
- Materials handling systems being commissioned
The dewatering operations continue at both United North and Main pit locations. United North is now complete and Main pit is progressing according to schedule. This process removes groundwater from historical workings, allowing safe access to underground development areas.
