West Wits Mining (ASX:WWI) - Qala Shallows Breakthrough Drives 70,000 oz Target Gold Production

Key Concepts

• Decline Development: The construction of inclined tunnels to access underground ore bodies.
• Stope/Stoping: The process of extracting the actual ore body from the surrounding rock.
• Dilution: The inclusion of waste rock in the extracted ore, which lowers the overall grade.
• Face Availability: The number of active mining fronts available, which dictates production flexibility and tonnage.
• All-In Sustaining Cost (AISC): A comprehensive metric for the total cost of producing gold.
• Reserve Conversion: The process of upgrading geological resources (inferred) to proven reserves through sampling and development.
• Mechanized Mining: Using heavy machinery for extraction, typically more cost-effective at depth compared to conventional methods.

1. Operational Milestones: The Level Two Breakthrough

The company has achieved a major operational milestone by completing a decline that provides access to the first reef drive level at the Kalashers project.

• Strategic Importance: This allows the mine to transition from development-heavy activities to active stoping in two directions.
• Impact on Grade: By moving away from large-scale development excavations (4.5m x 4.5m tunnels) toward targeted stoping, the company significantly reduces "dilution." This results in higher-grade ore delivery to the surface.
• Efficiency: The company is accessing previously unmined areas that were left behind historically due to lower gold prices and higher cut-off grade requirements.

2. Mining Methodology and Efficiency

The transition from development ore to stoping ore is the primary driver for improving the mine’s economic profile.

• Development vs. Stoping: Development ore is necessary for infrastructure but is highly diluted by waste rock. Stoping focuses on the ore body itself, yielding higher gold content per ton.
• Productivity Tracking: The company utilizes a daily reporting system to track:
  • Availability: Engine hours of equipment.
  • Utilization: The actual time machines are actively working.
• Equipment Fleet: The introduction of new Load-Haul-Dump (LHD) machines has improved maintenance scheduling and operational reliability, allowing for faster production cycles.

3. Scoping Studies and Future Growth

The company views the scoping study as a dynamic, phased process rather than a static document.

• Objective: The goal is to reach an "optimum plan" that balances mining methods, processing strategies, and economic trade-offs.
• Project 200: The company’s long-term aspiration is to increase production capacity significantly by leveraging existing resources.
• Processing Strategy: While owning a plant is the "first prize," the company is evaluating the use of third-party infrastructure in the region to save on capital expenditure, while also considering environmental factors like tailings deposition.
• Deep Mining: As the ore body becomes deeper and steeper, the company plans to shift from hybrid conventional stoping to 100% mechanized mining to maintain low unit costs.

4. Financial Outlook and Timeline

• Payback Period: By utilizing existing infrastructure and historical workings, the company has drastically reduced the time from project start to first ore production (achieved in weeks rather than years), which improves the project's internal rate of return (IRR).
• Break-even: The company estimates a 30-month timeline to reach the break-even point, with approximately nine months already elapsed.
• Funding: The company is finalizing a syndicate debt facility to fund the remaining project development to steady-state production, which is targeted for 2028 at 70,000 ounces.

5. Notable Quotes

• "A safe mine is a productive mine." — Rudy Deil, MD & CEO, emphasizing the link between operational discipline and safety.
• "The deeper we go, the higher the grades." — Highlighting the geological advantage of the Witwatersrand basin as the project progresses.

6. Synthesis and Conclusion

Vesvitz Limited is currently navigating a critical transition phase at the Kalashers project, moving from initial infrastructure development to consistent, high-grade stoping. By focusing on "face availability" and reducing dilution, the company is optimizing its mining profile to improve margins. The strategy is two-fold: achieving profitability at Kalashers while simultaneously preparing for broader growth in the Witwatersrand basin, including potential uranium and gold extraction at the Bird Reef Central project. The company’s focus remains on operational discipline, rigorous KPI tracking, and finalizing a definitive, optimized mine plan through its ongoing scoping studies.
