Andrada Mining has finished building a second processing plant at its Uis mine in Namibia. It will begin commissioning in the final week of August, a move the company says will materially increase tin production and advance its plan to double output.
The “Jig Plant” was delivered on time and within budget, the company said, calling it a low-cost upgrade that adds immediate capacity alongside the existing concentrator.
Chief Executive Anthony Viljoen said the project is timed to capture a firming tin market and to push Uis toward a larger, more efficient operating base.
“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,” Viljoen said.
Built adjacent to the current processing facility, the new plant is modular and can run independently to avoid disrupting primary operations.
It has been designed for a nameplate capacity of 80 to 100 tonnes per hour and can process up to 40,000 tonnes of ore per month, with a targeted recovery of about 70%.
Final operating parameters will be confirmed during the commissioning process.
Initial feed will come from nearby Uis pegmatites grading between 0.14% and 0.30% tin, as well as existing stockpiles.
To supplement this, Andrada has secured an ore supply agreement with Goantagab Mining for up to 20,000 tonnes of ore at around 1.5% tin.
The jig plant follows project milestones flagged earlier this year and is central to Andrada’s growth strategy at Uis, the company’s flagship operation in Namibia.
By adding parallel processing capacity, Andrada aims to increase throughput, improve recoveries from lower-grade sources, and reduce unit costs, while maintaining steady operation of the primary plant throughout the ramp-up.
Commissioning will test the plant’s circuits, validate recoveries and throughput, and integrate the new stream with mine scheduling and logistics.
Once commissioned, the additional capacity is expected to translate quickly into higher concentrate shipments, with the company guiding to a significant increase in tin output over the coming quarters.
Andrada, listed on AIM and the OTCQB, describes the Uis expansion programme as a platform for broader growth across its portfolio of critical raw materials in Namibia.
With construction now complete and commissioning imminent, the company’s near-term focus is on safely ramping the jig plant to nameplate and locking in the production gains it has signalled for 2025.
