Namibia-based Andrada Mining, formerly AfriTin, has renewed its offtake agreements with AfriMet and Thaisarco for tantalum and tin concentrate, respectively, while also receiving new funding to increase capacity.
The offtake agreement with African commodity trading firm AfriMet is for 12 months, starting on 1 January 2024, and will absorb all the production from the recently commissioned tantalum circuit at the Uis mine in west-central Namibia.
"The renewal of the tantalum offtake agreement secures all the company's tantalum production and, despite the small tantalum concentrate volumes, the additional revenue will incrementally improve profitability," Andrada chief executive Anthony Viljoen said. "Producing tantalum adds the second technology metal to Andrada's portfolio of products and is a positive step towards participating in the green transition."
Renewal of the offtake agreement with Thaisarco — a Thailand-based manufacturer of tin, tin alloys and tin-related products — for a further three years will start on 1 December. It entails a minimum supply of 90 t/month of tin concentrate and potentially up to 100pc of the expanded production.
The Uis mine has surpassed its nameplate capacity of 1,000 t/yr of tin metal and has significant potential for lithium and tantalum as by-products.
The company produced 398t of tin concentrate in the second quarter of 2023, and 238t in contained tin metal. The second quarter also saw the company complete the commissioning of its tantalum circuit and produce 225kg.
Earlier this year, Andrada started initial test campaigns to produce a saleable grade of lithium concentrate, it said.
Meanwhile, Andrada Mining said today that it has secured $25mn funding, comprising shares and convertible loan notes as part of a funding package announced in August with investment firm Orion. The funding will be used to increase tin production at the Uis mine, targeting a rate of up to 2,000 t/yr, and accelerate the lithium and tantalum revenue streams.
