AIM-listed Andrada Mining has reported a 13% year-on-year increase in contained tin production to 576 tonnes for the first half of its 2027 financial year, supported by higher feed grades and improved processing rates at its Uis tin mine in Namibia.

The company also secured N$98 million in funding to fully finance planned operational upgrades, including an ore-sorting circuit.

For the six months ended August 31, 2026, tin concentrate production rose 11% year-on-year to 955 tonnes. Quarterly contained tin production increased 6% to 290 tonnes, with concentrate production up by the same margin to 482 tonnes.

The average plant processing rate increased 7% year-on-year to 153 tonnes per hour. Ore processed rose 2% to about 539,000 tonnes, while the average feed grade increased 9% to 0.149% tin, compared with 0.137% tin in the first half of the previous financial year. Ore shipments rose to 36 during the half, compared with 25 in the same period a year earlier.

The N$98 million funding, secured by wholly owned subsidiary Uis Tin Mining Company from commercial bank Bank Windhoek and state-owned Development Bank of Namibia, covers the planned operational upgrades. Implementation has started, with long-lead equipment for the crushing component already ordered.

The ore-sorting circuit will reject lower-grade material before downstream processing, increasing the grade of material fed to the plant. Andrada expects the project to increase yearly tin concentrate production by 50% to 70%, to between 2,500 and 3,000 tonnes per year, translating to between 1,500 and 1,900 tonnes per year of contained tin. The company said higher concentrate production is also expected to reduce the applicable royalty rate, supporting improved operating margins and cash generation.

“This performance demonstrates the benefit of the operational improvements we have made at Uis and provides a stronger base from which to deliver the next phase of growth,” said CEO Anthony Viljoen. “The higher feed grades and processing rate supported the increased tin production, and the recently secured N$98-million bank funding package from Bank Windhoek and Development Bank of Namibia will enable us to implement the installation of the ore sorting circuit.”

Andrada will continue implementing the crushing and ore-sorting circuits during the second half of its financial year, alongside ongoing operational improvements at Uis.

The company will provide a broader update on its financial performance, portfolio development and outlook when it publishes its interim results.
