Andrada accelerates growth of its tin production Chamwe Kaira  Andrada Mining Limited has completed construction of its second processing plant at the Uis mine in Erongo.  The jig plant was built on time and within budget, and commissioning is set to begin in the final week of August. The new plant is expected to boost tin output significantly by adding more processing capacity.  Chief executive officer Anthony Viljoen said the completion of the jig plant on time and within budget is a smart, low-cost upgrade that will immediately boost Uis tin production on the completion of commissioning.  “The plant is a key milestone towards doubling production and positions Andrada well to capture the benefits of a robust and strengthening tin market.” The jig plant sits next to the existing tin processing facility and has a modular design that allows for scalable expansion.  It operates independently, ensuring uninterrupted production at the primary plant. It is built for a nameplate capacity of 80 to 100 tonnes per hour, with the potential to process up to 40 000 tonnes of ore per month at a recovery rate of 70%.  Actual performance will be confirmed during commissioning. Initial feedstock will come from nearby pegmatites with tin grades between 0.14% and 0.3%, as well as from stockpiles.  Andrada has also signed an agreement with Goantagab Mining to supply up to 20 000 tonnes of ore at a grade of 1.5% tin. The company said the jig plant is an important step in improving tin output and overall cost efficiency.  All of Andrada’s assets are located in the Erongo region, which hosts deposits of base, technology, and precious metals, as well as nuclear fuels.  The company holds two mining licences, Uis (ML134) and Lithium Ridge (ML133), and one exploration licence, Brandberg West (EPL 5445).

Andrada reports strong first quarter gains Chamwe Kaira Andrada Mining continues to show strong operational progress at its Uis site in the Erongo Region, reinforcing its role in Namibia’s critical minerals sector. Chief Executive Officer Anthony Viljoen said the first quarter of 2025 saw solid performance improvements at the Uis operation. These gains were supported by upgrades made through the company’s continuous improvement programme, including modifications to the Dense Media Separation (DMS) circuit. He said these changes led to higher processing rates and increased tin production, showing improved operational efficiency and reliability. “Production of our increasingly valuable byproduct tantalum improved notably, reinforcing our multi-mineral offering,” said Viljoen. He added that operational cost performance improved due to proactive cost-reduction measures, including the completion of a group-wide corporate restructuring aimed at lowering the cost base and improving profitability. Construction of a new jig plant is also progressing. Viljoen said the front-end crushing circuit has been delivered to Uis and commissioned, while other components are either being fabricated or in transit. Civil works have been completed. “Initial production is targeted to commence in the second half of the 2025 calendar year, aligning with project timelines and supporting the company’s growth objectives,” he said. During the quarter, the company processed 254,745 tonnes of ore, a 7% year-on-year increase and a 4% rise from the previous quarter. Viljoen said this marks a significant milestone in the company’s tin expansion strategy. Tantalum output also increased, driven by higher feed grades and the reprocessing of off-spec material. About 12 tonnes of concentrate were produced, containing 1.4 tonnes of tantalum. “Of this, 10 tonnes of concentrate were shipped to Afrimet during the period, reflecting ongoing offtake execution and consistent production delivery,” he said. On lithium development, Viljoen said the work plan and budget for Stage 1 of Lithium Ridge have been finalised. This triggered the drawdown of a US$7 million funding facility to support exploration and drilling. Regarding the Lithium Pilot Plant, Viljoen said talks with potential off-takers are ongoing and commercial discussions are progressing, despite a challenging pricing environment.

Andrada announces Uis exploration drilling results CHAMWE KAIRA  Andrada Mining Limited has announced initial drill results from 13 proximal pegmatites located within the Uis Tin Mine licence area (ML134) in Namibia’s Erongo Region. The company said the results reaffirm the scale and quality of mineralisation across the site and support its goal of expanding the production of tin, lithium, and tantalum—minerals critical to the global energy transition. These pegmatites are within a 3km radius from the existing processing plant at the Uis Tin Mine and constitute part of a swarm comprising approximately 180 mineralised pegmatites identified to date within the license area. The ongoing programme covering the 13 pegmatites comprises 44 diamond and 177 reverse circulation drill holes. The results in this announcement are for 136 holes (61%) because the company is awaiting analysis of the remaining 85 drill holes. Andrada CEO Anthony Viljoen commented, “These strong drill results reaffirm the scale and quality of mineralisation across Uis’s extensive swarm of pegmatites. High-grade intersections such as 1.13% tin, 1.76% lithium oxide, and 281 ppm tantalum validate our strategy to grow the resource towards 200 million tonnes and support future reserve definition.” Viljoen said the findings highlight the potential to re-establish the Uis Tin Mine as a significant global producer, with added value from lithium and tantalum. “The polymetallic nature of the deposit significantly enhances Uis’s economics and aligns with growing demand for critical metals across global markets,” he said. Andrada is focused on building a portfolio of high-quality technology metal assets across the Damara Belt. It currently operates a mine and processing facility at Uis and plans to expand production to include petalite (lithium). Viljoen added that the company is committed to unlocking the full value of Uis through disciplined investment and a targeted production scale-up strategy. “With a 5km strike length and broad mineralised zones, we believe Uis has the potential to become a cornerstone asset in Andrada’s long-term growth strategy.” Tin iTantalum is valued for its multiple uses relevant to the transition, particularly for its application as a solder. Its demand is increasing and is likely to outstrip supply in the long term. TTalalum, a transition metal renowned for its high melting point and corrosion resistance, finds numerous applications in the renewable energy sector, such as capacitors in wind turbines, solar energy systems, energy storage systems, and corrosion-resistant coatings. Lithium is a crucial component of energy storage and has an important role to play as renewable energy is increasingly integrated into national grids. The requirements of the energy transition can indeed be translated into an economically beneficial outcome.
