Rox Resources Youanmi Project Completion Accelerates with 24-Hour Mining

Rox Resources Accelerates Youanmi Operations with 24-Hour Mining and Infrastructure Completion

Rox Resources Limited (ASX: RXL) has reached a significant operational milestone at its flagship Youanmi Gold Project, transitioning to round-the-clock mining operations whilst completing critical infrastructure developments. The Rox Resources Youanmi project completion represents a major step forward for the Western Australian gold developer as it rapidly advances toward production at what is set to become one of the state's highest-grade new gold operations.

The company has successfully established portal support at United North, completed construction of its phase 1 camp expansion and site offices, whilst maintaining dewatering progress at the Main pit according to schedule. With 122 metres of advance completed to date and 60 new high-specification accommodation rooms now operational, Rox is demonstrating strong execution momentum as it approaches first gold production.

Mining Operations Scale to 24-Hour Operations

Following the first cut fired in November 2025, Rox has successfully transitioned United North mining operations to continuous day and night shifts. This operational upgrade has delivered immediate results, with approximately 122 metres of advance completed as crews maintain advance rates in line with project expectations.

The establishment of portal support marks a crucial infrastructure milestone, with ground conditions appearing as expected during the exploration decline development. Furthermore, the company's mining partner Byrnecut is well-positioned to commence the primary ventilation portal once the pad advances across the United North pit.

Key Mining Progress Indicators:

• Portal support: Fully established and operational
• Ground conditions: Meeting geological expectations
• Advance rates: Tracking to planned timeline
• Operational status: 24-hour mining cycles active
• Next phase: Primary ventilation portal commencement

"Mining operations at United North have rapidly accelerated over the past few weeks following the firing of the first cut in November, which marked the beginning of our journey as a gold producer." – Managing Director Phill Wilding

Infrastructure Development Reaches Key Milestones

Rox has completed construction of its 60-bed phase 1 camp expansion, bringing high-specification accommodation online to support the growing operational workforce. In addition, the company has committed to expanding total camp capacity to approximately 350 rooms with completion anticipated in the first half of 2026.

Site office construction has reached practical completion, with dedicated mining offices now ready for occupation by both Rox and contractor personnel. Moreover, underground workshop preparations are well advanced, with pad works completed and concrete works set to commence imminently.

Infrastructure Completion Status:

Dewatering Operations Progress on Schedule

Main pit dewatering continues according to plan, with pumping operations discharging to evaporation ponds and the Kathleen pit. Consequently, the company remains on schedule to complete dewatering activities in Q1 2026, with evaporators to be commissioned shortly via separate pump feed to maintain this critical timeline.

The successful dewatering progression is essential for exposing the Main and Pollard portal positions, enabling the next phase of underground development access. However, maintaining this schedule requires continued operational excellence across all dewatering systems.

Understanding Mining Development and Closure Proposals (MDCP)

A Mining Development and Closure Proposal is a comprehensive regulatory submission required in Western Australia that outlines how a mining operation will be developed, operated, and ultimately rehabilitated. The MDCP covers environmental impacts, safety protocols, community engagement, and post-mining land use.

For investors, MDCP approval represents a critical regulatory milestone that removes operational uncertainty and enables construction activities to commence. For instance, Rox's planned MDCP lodgement for processing plant and tailings infrastructure represents the final major permitting hurdle before full development can proceed.

What Does MDCP Cover?

• Environmental impact assessments and mitigation strategies
• Safety protocols and risk management frameworks
• Community consultation and stakeholder engagement plans
• Rehabilitation strategies and closure planning
• Water management and waste disposal protocols

Pathway to Production Maintains Timeline

The Rox Resources Youanmi project completion pathway remains on track following the Definitive Feasibility Study released in November 2025 and the ongoing equity funding component expected to complete in December 2025. Furthermore, the company is advancing multiple critical work streams simultaneously to maintain production timeline integrity.

Current Development Activities:

• Front End Engineering Works (FEED) underway for processing plant
• Tenders under review for fine grind mill, power supply, EPC pricing, and oxygen plant
• Owners Team embedded with preferred partner Increva
• Underground drilling tender under assessment
• Long lead item procurement actively progressing

Why Front End Engineering Works Matter

Front End Engineering Works represent the detailed design phase that bridges concept studies with construction execution. This critical phase ensures all technical specifications, cost estimates, and construction methodologies are thoroughly validated before Final Investment Decision.

Immediate Next Steps (Q4 2025 – Q1 2026):

• Finalise detailed mine planning and scheduling
• Award contracts for long lead items
• Continue United North exploration decline development
• Complete Main pit dewatering to expose portal positions
• Finalise FEED works and EPC contracts
• Progress debt financing discussions toward Final Investment Decision

Investment Thesis: High-Grade Gold Production Story

Rox Resources offers investors exposure to one of Western Australia's most compelling high-grade gold development stories. With a global mineral resource of 12.1Mt at 5.6g/t for 2.2Moz of gold, the Youanmi Gold Project represents exceptional grade quality in the current gold development landscape.

The company's execution momentum demonstrates management's ability to deliver on operational milestones whilst maintaining cost discipline. In addition, the transition to 24-hour mining operations, combined with completed infrastructure developments, validates the project's technical feasibility and operational readiness.

Key Investment Highlights:

What Makes Youanmi Project Exceptional?

The Rox Resources Youanmi project completion stands out in the current gold development landscape for several compelling reasons. The project's 5.6g/t gold grade places it among the highest-grade new gold developments in Western Australia, significantly above the typical 2-3g/t grades seen in many contemporary projects.

Geological Advantages

The Youanmi district has a rich mining history spanning over a century, with historical production exceeding 680,000 ounces of gold. However, this extensive geological understanding provides confidence in resource continuity and mining conditions.

Furthermore, the project benefits from established infrastructure including sealed road access, grid power availability, and proximity to established mining services in the region. Consequently, these advantages reduce development risk and support faster construction timelines.

Operational Excellence Indicators

• Proven mining contractor with Byrnecut partnership
• Strong safety performance during development phase
• Consistent delivery against planned milestones
• Effective cost control throughout development
• Robust project management frameworks
