Andrada Mining Uis Mine Namibia Achieves Record Processing Performance

Processing Efficiency Breakthroughs in African Mining Operations

The African mining sector continues to evolve as technological advancement and operational optimisation reshape traditional extraction methods. Furthermore, the Andrada Mining Uis mine Namibia operation exemplifies how mining industry evolution integrates with processing excellence to achieve superior performance metrics. Understanding these developments requires examining the complex interplay between geological advantages, processing technologies, and market dynamics that define modern mining excellence.

Processing plant efficiency represents a critical benchmark for evaluating mining operation success, with throughput rates, recovery percentages, and operational consistency serving as key performance indicators. In addition, the integration of continuous improvement programs across African mining operations reveals sophisticated approaches to capacity optimisation that extend beyond conventional production metrics.

What Drives Superior Processing Performance in Namibian Tin Operations?

Advanced Processing Plant Optimisation Strategies

Namibian tin mining operations have achieved remarkable processing efficiency improvements through systematic implementation of continuous improvement methodologies. Recent performance data indicates processing rates reaching 146 tonnes per hour, representing a substantial 12% year-over-year improvement that demonstrates sustained operational enhancement rather than temporary productivity gains.

The technical achievement of maintaining processing rates above target levels while simultaneously conducting scheduled maintenance activities reflects sophisticated operational planning. Processing volumes of 259,396 tonnes during Q3 2025 represent an 8% year-over-year increase, indicating consistent capacity utilisation despite planned maintenance windows.

Key Processing Metrics:

• Processing rate: 146 t/h (+12% YoY improvement)
• Ore throughput: 259,396 tonnes (+8% YoY increase)
• Target processing rate: 140 t/h (exceeded by 4.3%)
• Operational consistency maintained during maintenance periods

The continuous improvement program implementation demonstrates measurable impact on operational efficiency, with processing plant performance described as stable and predictable by operational management. Consequently, this predictability enables strategic maintenance scheduling without compromising production commitments or market responsiveness.

Metallurgical Recovery Excellence and Technical Innovation

Tin recovery rates of 73% consistently exceed industry targets of 70%, representing the third consecutive quarter of superior metallurgical performance. However, while experiencing a minimal 1% year-over-year decline from the previous 74% recovery rate, operational performance remains well above strategic thresholds.

The maintenance of high recovery rates during crushing circuit upgrades indicates robust metallurgical processes capable of withstanding operational disruptions. Moreover, technical analysis reveals that processing 259,396 tonnes of ore while achieving 73% tin recovery demonstrates exceptional mineral liberation and concentration efficiency.

Recovery Performance Analysis:

The technical achievement of producing 429 tonnes of tin concentrate with 255 tonnes of contained tin yields an average contained tin percentage of approximately 59.4%. This indicates high-grade concentrate production suitable for premium market positioning.

How Do Production Metrics Position Uis Mine in Global Context?

Production Capacity and Annual Output Projections

Tin concentrate production of 429 tonnes during Q3 2025 represents a 14% year-over-year increase, significantly outpacing the 8% increase in ore throughput. For instance, this divergence indicates improving ore grades or enhanced metallurgical efficiency beyond simple capacity expansion.

Contained tin production of 255 tonnes reflects a 10% year-over-year improvement, providing substantial contribution to global tin supply. Furthermore, annualised production projections based on Q3 2025 performance suggest capacity for approximately 1,716 tonnes of tin concentrate annually, containing roughly 1,020 tonnes of tin metal.

Management emphasises that operational results provide positive indications of latent value within operations that the company aims to unlock, demonstrating confidence in the phenomenal geology at Uis.

The strategic timing of 15 quarterly tin shipments represents a 7% year-over-year increase and 25% quarter-over-quarter improvement. Additionally, this optimises revenue capture during favourable pricing conditions with tin prices exceeding $40,000 per tonne.

Strategic Shipment Optimisation During Market Cycles

Shipment frequency optimisation reflects sophisticated market timing strategies, with quarterly shipments increasing from approximately 12 in Q2 2026 to 15 in Q3 2025. This 25% quarter-over-quarter increase aligns with elevated tin pricing, demonstrating operational flexibility to capitalise on favourable market conditions.

The strategic emphasis on maximising value through optimal product mix reflects market-responsive production planning rather than fixed quota systems. In addition, production scheduling accommodates both maintenance requirements and market opportunity windows, indicating advanced operational planning capabilities.

Shipment Strategy Elements:

• Q3 2025 shipments: 15 total (+7% YoY, +25% QoQ)
• Revenue optimisation during $40,000/t tin pricing
• Flexible production scheduling around maintenance windows
• Market-responsive inventory management

What Technical Infrastructure Developments Enhance Operational Capabilities?

Jig Plant Commissioning and Processing Technology Integration

New jig plant commissioning progressed through phased implementation during Q3 2025, with systematic approach supporting progressive operational throughput during equipment integration. However, initial operational challenges related to fines build-up and shaking table configuration are being addressed through collaboration with equipment manufacturers.

The technical approach of utilising Uis ore for jig plant optimisation until third-party ore sources become available demonstrates prudent capacity management. Furthermore, this strategy maintains operational continuity while optimising new equipment performance parameters before external ore processing commitments.

Equipment manufacturer collaboration for troubleshooting demonstrates industry-standard approaches to complex metallurgical equipment integration. Technical solutions for fines management and shaking table optimisation require specialised expertise typically available through original equipment manufacturer support.

Third-Party Ore Processing and Regional Hub Development

High-grade ore supply agreements with Goantagab represent strategic diversification beyond internal ore sources. Moreover, management remains optimistic about reaching implementation agreements that enable expansion of processing capacity utilisation through external ore partnerships.

The commitment to building value-accretive third-party ore partnerships reflects regional hub development strategy, positioning the operation as a processing centre for multiple ore sources within Namibia's mining regions.
