Andrada accelerates growth of its tin production

Andrada Mining Limited (AIM: ATM, OTCQB: ATMTF), a tin producer with a portfolio of critical raw materials mining and exploration assets in Namibia, is pleased to announce the completed construction of the second processing plant ("Jig Plant") at the Company's flagship Uis mine.

HIGHLIGHTS

• Construction of the Jig Plant has been completed on time and within budget.
• Commissioning of the Jig Plant to commence in the final week of August 2025.
• Tin output expected to significantly increase through additional processing capacity granted by the Jig Plant.

Anthony Viljoen, Chief Executive Officer, commented:

"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."

Jig Plant CONSTRUCTION update

Construction of the Jig Plant, located adjacent to the existing tin processing facility, has been completed, with commissioning scheduled for the last week of August 2025. (See announcements dated 12 February 2025 and 17 June 2025). The modular design allows for scalable expansion while operating independently, ensuring uninterrupted production at the primary processing plant. The Jig Plant is designed for a nameplate capacity of 80 to 100 tonnes per hour, with a potential to process up to 40 000 tonnes of ore per month at a potential recovery rate of 70%. Actual operating parameters will be confirmed during the commissioning process. Initial feedstock will be sourced from the Uis proximal pegmatites with grades of between 0.14% and 0.3% tin, and existing stockpiles. Andrada has also secured an ore supply agreement with Goantagab mining to provide up to 20 000 tonnes of ore at a grade of 1.5% tin. (See announcement dated 17 June 2025). The Jig Plant represents an important step in enhancing the Company's tin production output and overall cost efficiency.
