Name of the Project
Uis lithium expansion project.

Location
In the Erongo region of Namibia, on mining licence ML134. 

Project Owner/s
Critical raw materials producer Andrada Mining, through its subsidiary Uis Tin Mining Company (UTMC). 

Project Description
The Uis mine exploits a polymetallic pegmatite-hosted deposit containing tin, tantalum and lithium mineralisation. The mine currently produces tin and tantalum concentrates. 

Andrada intends to monetise the lithium contained in the run-of-mine by building a beneficiation circuit that is integrated into the tin and tantalum processing facility of the Uis mine. 

The additional integrated circuit will not increase the ore requirements from the mining operation but will rather reprocess the waste material from the tin and tantalum concentrator for lithium enrichment. 

Lithium mineralisation predominantly occurs as petalite. During the initial phase, petalite concentrate will be produced for the technical lithium market at an initial target of 50 000 t/y. 

Previous feasibility studies towards this initial phase have advanced the project to a prefeasibility level of confidence. Definitive feasibility study (DFS) work is expected during 2026. 

Andrada envisages a second phase of development to supply the lithium refining industry with concentrate for producing lithium chemicals for the fast-growing battery industry.

Latest Developments
On February 10, 2026, Andrada announced that UTMC had entered into a cooperation agreement with the European Investment Bank (EIB) to accelerate the feasibility study for the lithium expansion project. Under the agreement, the project will benefit from technical and project development assistance funded by the EU and valued at up to €2-million on a grant basis. The scope of work is intended to advance the project to bankable feasibility level, with a focus on metallurgical testing and related infrastructure studies. 

Andrada has also signed a cooperation agreement with the EIB to accelerate the feasibility study for the expansion, with EU-funded technical and project development assistance intended to advance the project to bankable feasibility. The company has said the partnership provides nondilutive support and is aimed at accelerating implementation of the project.
