As the year draws to a close, Andrada Mining Limited (AIM: ATM, OTCQB: ATMTF) has delivered a strong operational performance for the quarter ended 30 November 2025, reinforcing the Uis Mine’s role as a scalable production base at a time of tightening global tin supply and rising prices. The quarter highlights a business shifting from stabilisation to momentum, underpinned by operational efficiency, favourable markets and accelerating exploration across its broader Namibian portfolio.
Andrada’s Chief Executive Officer Anthony Viljoen said, “The quarter demonstrated visible momentum across the business with operational improvements beginning to unlock the latent value of the Uis asset. The combination of existing production, expanding exploration footprint and exposure to multiple high-demand minerals positions our company at the forefront of critical mineral development in Africa.”
At Uis, Andrada’s Continuous Improvement programme (CI2) continued to translate into measurable gains. Processing throughput rose 12% year-on-year to 146 tonnes per hour, while tin recovery remained stable at 73% above the Company’s 70% target for a third consecutive quarter. Higher throughput drove a 14% increase in tin concentrate production to 429 tonnes and a 10% rise in contained tin to 255 tonnes. Ore processed increased 8% year-on-year to 259,396 tonnes, demonstrating sustained plant reliability and predictability.
These gains were delivered into a sharply improving market backdrop. Tin prices rose approximately 40% year-to-date in calendar 2025, surpassing US$40,000 per tonne in early December. Andrada increased shipments to 15 during the quarter, up 25% quarter-on-quarter, aligning sales with elevated pricing in what management describes as a structurally tight market. As the only tin producer listed on AIM, the company is uniquely positioned to capitalise on this upswing.
Operationally, quarterly tin output was marginally lower than the prior quarter due to scheduled maintenance and CI2-related downtime on the crushing circuit, work considered essential to sustaining higher long-term throughput. Plant availability remained strong at 91%, with management maintaining a flexible production strategy across tin and tantalum to optimise value under prevailing market conditions.
Development work at Uis also progressed. Commissioning of the new jig processing plant advanced under a phased ramp-up strategy, with early commissioning issues being addressed alongside equipment manufacturers. The jig plant is expected to enhance recovery and processing flexibility once fully operational. In parallel, Andrada reiterated its confidence in the long-term potential of high-grade third-party ore supply from Goantagab, while continuing to pursue additional regional feedstock partnerships.
Beyond tin, Andrada’s critical minerals growth strategy continues to take shape. At Lithium Ridge, drilling accelerated under the joint venture with SQM, with a third rig deployed to fast-track exploration of spodumene-bearing pegmatites. Initial assay results are expected in the first half of calendar year 2026. At Uis, discussions with potential offtake partners for petalite are ongoing, supported by metallurgical testwork and evaluation of production pathways, with outcomes expected in the second half of 2026. Exploration success at Brandberg West further strengthens the company’s diversification narrative, with copper grades up to 2% and notable tungsten intersections reinforcing optionality across multiple critical minerals at a time of growing global supply constraints.
Looking ahead, Andrada is focused on completing jig plant commissioning, further optimising plant performance, advancing lithium integration studies, progressing exploration at Brandberg West, and evaluating third-party ore agreements. With a robust operational platform now established and strong commodity fundamentals in place, the Company enters the new year positioned for sustained growth across tin and its broader critical minerals portfolio.
