Andrada Mining Limited’s tin concentrate production increased by 15% to 1,740 tonnes, with contained tin output rising by 11% to 1,036 tonnes in the fourth quarter of the financial year ended February 2026.
The company said ore processed rose by 8% to 1.04 million tonnes during the period, while the processing rate increased by 7% to 146 tonnes per hour.
Quarterly results also reflected year-on-year gains. Ore processed increased by 5% to 255,320 tonnes, while the processing rate rose by 9% to 153 tonnes per hour. Tin concentrate production climbed by 20% to 453 tonnes, with contained tin output up 19% to 271 tonnes.
Chief Executive Officer Anthony Viljoen said the quarter marked a key step in the company’s long-term strategy.
“The fourth quarter has been a defining period for Andrada. We are delivering on our strategy of consolidating highly prospective historic mining assets and attracting world-class partners to accelerate their development, at a time of strong commodity prices and the growing strategic importance of critical minerals,” he said.
The company attributed the improved performance to enhanced plant stability, higher feed grades and improved recovery rates, which reached 73% during the quarter. It said the gains reflect ongoing optimisation initiatives at its operations.
During the period, Andrada prioritised tin production over tantalum recovery to take advantage of elevated tin prices, which reached approximately N$940,000 (US$55,000) per tonne towards the end of the financial year. The strategy, together with higher output and cost optimisation, supported positive cash flow.
The company also advanced several strategic initiatives aimed at supporting long-term growth and diversification.
At Brandberg West, Andrada secured a phased investment partnership with ACAM LP valued at N$871 million (US$51 million), with an initial N$107 million (US$10 million) already received. The funding will support feasibility studies, tailings recovery and pit optimisation. Historical drilling at the site has confirmed high-grade mineralisation, including up to 10.55% tin, 3.53% tungsten and 1.95% copper.
“The conclusion of the Brandberg West partnership with ACAM provides exposure to a high-grade tungsten project with associated tin and copper credits, at a time of strong tungsten prices,” Viljoen said.
At Lithium Ridge, initial drilling results confirmed high-grade lithium mineralisation of up to 3.02% Li₂O, alongside tin and tantalum. The project is being advanced in partnership with global lithium producer SQM, with early results indicating the potential for a large-scale, long-life polymetallic asset.
“The geological work undertaken this quarter at Lithium Ridge indicates that it could emerge as a significant lithium discovery. The accelerated drilling programme in partnership with SQM will support rapid advancement of the project,” Viljoen said.
At Uis, Andrada’s subsidiary, Uis Tin Mining Company, secured up to N$39 million (€2 million) in non-dilutive funding from the European Investment Bank. The funding will support a feasibility study to integrate lithium processing into the existing operation.
“Tin concentrate production increased by 20% year-on-year, reflecting continued operational improvements and supporting cash flow generation across the group. The extension of our partnership with our tin off-taker, Thaisarco, as well as funding from the European Investment Bank, adds further value as we scale production at Uis,” Viljoen said.
