Andrada Mining, listed on both Aim and OTCQB, has posted a solid operational and financial performance for the six months ended 31 August 2025, driven by increased metal output, revenue growth and improved cost discipline.
The company credited the positive results to sustained capital investment and ongoing processing optimisation across its asset base. Ore processed rose 10% year-on-year to 527 583 t, up from 481 504 t in the first half of FY2025. Tin concentrate output climbed 14% to 858 t, while tantalum concentrate production increased 12% to 27 t.
Revenue for the period strengthened by 12% to £12.2-million. The operating loss narrowed to £900 000, compared with £1.5-million in the previous interim period, supported by a 26% reduction in administrative expenses following a corporate restructuring. The company also benefited from higher tin prices, which averaged $33 154/t — a 6% increase year-on-year.
Uis Mine Development Accelerates
Andrada confirmed that engineering enhancements over the past year have reinforced the foundation for accelerated growth across its core projects. The Uis mine development programme in Namibia aims to expand tin and tantalum production while introducing lithium concentrate from the same ore stream. The strategic focus remains on boosting throughput and lowering unit costs to strengthen future margins and cash flows.
The Uis ore sorter project — expected to lift tin and tantalum production by approximately 60% — has undergone a redesign that cuts capital costs by more than 20%. Long-lead items have arrived on site, with fabrication scheduled for the first half of 2026 and commissioning anticipated in the second half.
The Uis lithium expansion, which introduces a new beneficiation circuit integrated into the existing processing plant, has passed a technoeconomic evaluation. Andrada is progressing toward a definitive feasibility study and is engaging with prospective offtake and development partners.
During the period, exploration focused on 13 pegmatites within 3 km of the processing plant, as part of a broader drilling programme comprising 44 diamond and 177 reverse-circulation holes. Early intersections have been encouraging, including grades of 1.13% tin, 1.76% lithium oxide and 281 ppm tantalum, supporting the company’s target of expanding the resource base to 200-million tonnes.
Jig Plant Progress and Third-Party Agreements
Construction of the jig plant, developed with Birca Mining, was completed in August. However, commissioning has been delayed due to material flow challenges, which are currently under technical review.
A separate ore-supply and profit-sharing agreement with Goantagab Mining has experienced setbacks following a court ruling that halted major operations on the Goantagab claims. Andrada plans to feed the jig plant with ore from Uis until the third-party supply resumes.
Lithium Ridge Exploration Gains Momentum
At Lithium Ridge, the company’s partnership with SQM Australia advanced after receiving approval from the Namibian Competition Commission. A fully funded exploration programme commenced in August, featuring 14 000 m of diamond drilling across roughly 120 holes, aimed at testing depth extensions and mineralisation continuity.
CEO Outlook
“We are now transitioning from capacity build-up into a scaling phase. Our growth potential far exceeds our current operational footprint,” said CEO Anthony Viljoen.
“The period’s results highlight meaningful improvements in cost performance, cash discipline and operating leverage. With a portfolio of critical minerals — tin, tantalum, lithium, tungsten and copper — in an investment-friendly jurisdiction, we are positioning the group as a strategic supplier for the future.”
